2. SAFETY INSTRUCTIONS

! Any serious incident that occurs in relation to this medical device should be reported to

STERIS and the competent authority of the member state in which the user and/or patient

is established.

! warning The modiﬁcation of medical device without manufacturer authorisation is prohibited.

Pinch points

! During patient positioning, moving dierent sections of the tabletop and using extensions and

accessories can cause pinch points to appear, which can injure the patient or the surgical

team. Typical pinch points are shown below:.

! During Trendelenburg and right tilt movements, take care to check that the connections

(charger, hand control or foot pedal) are plugged into the interface to prevent damage to the

cables or connectors.

Precaution during the movements

! Before any movement activation, be sure that there is no risk of contact or collision with an

object, on equipment or a person.

! Do not place any objects on the base of the column because they could become jammed when

the sliding covers on the column are lowered.

Stability

! Once the GMAXTR column is on the ﬂoor, ensure that it is stable. If not, move it if necessary to

ﬁnd a ﬂatter ﬂoor surface, or use the adjustable foot of the base.

Moving with a patient

! When moving the tabletop with a patient on it, the patient must be centred more or less over

the trolley attachment.

It is strongly recommended that you use barriers or another system to hold the patient in place.

! The trolley is not intented to cross threshold, to ascend or to descend step. Always move the

trolley very carefully.

! Before going anywhere, ensure that there are no obstacles along the way you wish to use.

When you set o, move the trolley very carefully. Adapt your speed to the environment (i.e.

corridor width, corner angles, doors, etc.).

Switching the table on

! Every time you turn the table on, check that the pre-selected patient orientation corresponds to

what you want to do. When you switch o the table, the automatic patient orientation pre-

selection is memorized, but the manual selection is not.

If the main hand control and the optional pedal are used at the same time, the hand control

overrides the pedal.

Switching the table o

! The STOP keys on the main hand control and on the backup system allow you to stop all table

movements.

They deactivate the optional pedal and other external control mechanisms.

Handling the surgical table

! Avoid handling the surgical table roughly during the operation or transfer. Do not exert excessive

lateral loads on it, do not pull or push the surgical table with the accessories or with the rails.

! Avoid rough handling of the hand control and the backup system. Do not press the keys with

too much force or using unsuitable objects. Protect the hand control from colliding with the

table.

! Do not sit on one of the two ends of the table, especially when the tabletop is not centered, as

this can cause the table to tilt.

! Avoid handling the cables roughly when connecting or disconnecting the hand control, the foot

pedal or the power cord set.

! When power cord is connected to the surgical table, and therefore is lying on the ﬂoor, pay

attention to this power cord when moving around the surgical table and remove the cable

before moving the table.

Load limits

! Do not exceed a patient+accessory weight of 250kg for the standard described positions and

respect the indications and warnings signaled.

! The use of certain extensions may decrease this patient + accessories weight. When

extensions are installed on Gmax™ tables, the user manuals of these extensions should also

be consulted to ﬁnd out the possible weight restrictions related to the use of these extensions.

! It is possible to reach 360kg patient+accessory weight only for the bariatric described

positions.

! In positions where the tabletop will be signiﬁcantly slide away from the column, ensure that

there is sucient stability for the type of surgical procedure requirements.

! For all other uses, please contact our network for advice. If you are working intensively on the

patient’s chest, we recommend that you bring the tabletop back to a centered position on the

column.

Positioning the patient

! The positions described in this manual are given purely as examples. The required accessories

are not always shown. Under no circumstances should these instructions replace the

instructions given by the surgical team in charge of the patient.

! Ensure the stability of the patient and the table when making combined position.

! Secure the patient properly (ex. using straps), especially when the table has a strongt tilt

inclination.

! Long surgical procedures can cause compression points on patients and have post operative

consequences. Monitor patient during surgical procedures and use gel cushions for extented

procedures.

! During table movements (rev. Trend/Trend, up/down, left/right tilt), a minimum distance should

be left between the c-arm and the patient, to avoid any contact between them during handling.

Autonomy

! A lithium-ion battery is integrated into both the column and the hand control, meaning they can

function with being plugged in. Before using the table, check that the batteries are suciently

charged.

Connections

! The sockets are equipped with locks: do not pull on the hand control or pedal cables to

disconnect them. The internal E-Serve connection is only to be used by technician sta and

with equipment approved by STERIS

! Always use the power cord provided by STERIS.

! The operator should never touch the patient when the operator is plugging or unplugging

the hand control or the the pedal, or when the operator is handling the connectors of these

devices.

Installation (for CPS02G and GMAX ST)

! The ﬁxed components should not be installed in areas where there is a risk of explosion

(presence of ﬂammable anaesthetic gas)

! Installation operations should only be assigned to STERIS technicians or technicians certiﬁed by

STERIS, and should be carried out according to the installation instructions prepared by STERIS.

Contact the STERIS installation department

! Disconnect all equipment before installing the table. Do not install the GMAX™ unless all

elements of the GMAX™ System have been properly locked.

Transfer System - GMAX™

[5]

Potential equalisation

! Connect potential equalisation conductors to prevent the problem of diering potentials in

networks.

! Originally intended for cardiac areas, it protects the patient from electric shock during

procedures where even small potentials may cause harm.

! When a potential equalisation conductor is connected, the table MUST NOT be used with a

deﬁbrillator

! When the use of the potential equalisation conductor allows an medical electrical system to be

created, then this system must meet the requirements of IEC 60601-1.

Antistatic link

! If antistatic connection is necessary, we recommend that you use only the pads that have been

specially developed for this product. Put the patient in direct contact with them and use the

table on an antistatic ﬂoor, or connect it to an equipotential cable using the socket designed

for this.

Electrical safety

! Warning: To prevent any risk of electric shock, this appliance should only

be connected to a grounded power supply.

! The Gmax™ table must always be positioned so that the power cord can be disconnected

easily when connected to the table with mobile power supply CPS01G.

! The power cord with its mains plug is thus the device used to isolate the transportable column

GMAXTR from supply mains.

! The mains supply switch “0 / I” on the front of wall-mounted power supply CPS02G, is used to

isolate the GMAX ST stationary column from the mains supply.

! It is preferable to use the batteries instead of the mains if you have doubts about the protective

ground in the operating room.

! The use of high-frequency surgical equipment, cardiac deﬁbrillators, and cardiac deﬁbrillator

monitors in association with the Gmax™ table creates a risk of burns, explosion, or electrical

shock. The user must be aware of this.

! Comply strictly with the manufacturer’s instructions.

Accessories

! If accessories made by other manufacturers are used, it is the user’s responsibility to check

that they are compatible with Gmax™ and that they do not endanger the patient and the

surgical team

! Before connecting accessories to the surgical table, check the general state of them to ensure

that they are not degraded and that the connection system is not damaged.

! The end user should ensure in particular that the intended use and the conditions of use

(including the maximum patient weight) of accessories made by other manufacturers are

compatible with the claims of the Gmax™ surgical table.

Electro-Magnetic Compatibility

! If the table is used close to other electrical equipment, ensure that the latter complies with the

regulations in force regarding electromagnetic compatibility. If high frequency equipment (such

as a deﬁbrillator) is used, ensure the manufacturer’s instructions are followed closely.

Emergency mode

! When the backup system is used, the other control systems, including the main hand control,

are automatically switched o. The ALS sensors can also be disabled, so when you move the

tabletop you will need to ensure that you look out for potential conﬂicts between the sections.

The pre-selected patient orientation set as default is the normal orientation.

Cleaning

! Do not use any chlorine-based products or chlorine derivatives due to the risk of corrosion.

Ensure that the socket protection ﬂaps correctly cover the plugs so that ﬂuids do not get in.

Before cleaning the column, ensure that it is switched o and disconnect the hand control. Put

on the socket cover.

! Do not immerse the hand control and do not spray cleaning products directly onto the sockets.

! After cleaning, ensure no residual water remains near the mains plug.

Hand control storage

! When the hand control is not in use, we recommend hanging it on a table rail or placing it on

the charger unit to prevent any keys being pressed accidentally. Handle the hand control and

its cable with care.

Environmental conditions

• Transport / storage: temperature 0°C-65°C, humidity 10-85% Pressure non-condensed 500-

1060 hPa, battery fuses removed.

• Use: temperature 10°C-40°C, humidity 10-75% non-condensing, pressure 800-1060 hPa

nota: at 40°C, temperature at the pads are equal to 42°C

• Local pressure to the ﬂoor: 0,2kg/cm2 under the base

! When the RCT01G is used with trolleys and the GTOPGX, the temperature for use should not

exceed 25°C.

! Do not use the table in the presence of ﬂammable anesthetic gas, or in areas subject to

explosive risks.

! Gmax™ must not be used in the vicinity of strong magnetic ﬁelds (MRI environment)

! Gmax™ is not intented to operate in an oxygen rich environment

! GMAX™ is not intented for outdoor use, and shall not be exposed to high humidity for extented

periods.

X-Ray radiation

! The GTOPGX tabletop should not be considered to be a patient support system for radiology

procedures. The Gmax™ transfer system does not consist of associated equipment for a

radiological set-up. This means that if the operating table materials are exposed to an x-ray

beam, it does not have optimal radiolucent performance and this may lead to interference with

the information, potentially resulting in harm to users. Radiological protection devices should

therefore be worn by users when using radiology equipment with the Gmax™ transfer system.

Maintenance

! The safety, reliability and proper operation of the surgical table can only be ascertained and

granted by STERIS. Repair and adjustments should only be assigned to STERIS technicians or

approved technicians.

! Observe the maintenance schedule set out by STERIS and described in this document.

! Never try to adjust or repair the surgical table yourself.

! No interventions may be undertaken on the GMAX™ transfer system before all electrical power

is switched o and made safe.

! During maintenance and repair, only original parts must be used.

! While the surgical table is in use with a patient, no software update should take place and no

part of the operating table should be serviced or maintained.

Main characteristics

The Gmax™ Transfer System has been designed to respond to the latest expectations in surgery in the easiest and safest way. Each transfer system is made of multi-

section operating tabletops, columns and bases, a trolley to transfer the operating tabletop and a colour touch screen hand control. It has been designed to optimize

operating theatre procedures and guarantee ﬂexibility, versatility, and intuitive use.

Because it is highly modular and adaptable and makes use of speciﬁc tabletops and accessories, the operating table can satisfy all the needs of the dierent surgical

specialties.

The movements allow the user to automatically conﬁgure the operating table for dierent surgeries and surgical approaches without the need to manually move the

section.

The tabletop adjusts to the patient, rather than the patient to the tabletop. The capacity of the Gmax™ Transfer System is 360 kg in the bariatric position.

The Gmax™ Transfer System is made up of the following elements, at minimum:

• 1 operating table column (mobile or ﬁxed) and charger

• 1 interchangeable operating tabletop (made up of multiple sections)

• 1 trolley (ﬁxed or with variable height and Rev. Trend/Trendelenburg)

• 1 hand control with Bluetooth connection and cable

The almost unlimited possible combinations of the sections are matched with automatic detection of the different sections. This makes the table much

easier and safer to use: any changes in the orientation of the head and leg sections are automatically recognized by the system and managed safely.

The transfer trolley can be inserted around the column from the head or foot end within a 100-degree angle range, allowing the trolley to be steered around equipment and

obstacles in the operating theatre. In addition, with the same trolley, you can transfer the tabletop only or move the tabletop and the column together.

Inserting and removing the battery fuse:

For reasons of safety during transport, the battery fuse is packed

separately.

1. Insert the fuse into the separately provided fuse holder.

2. Push and turn in order to lock the fuse holder.

If the table is not used for a long period of time (>1 month), remove the fuse to

limit loss of battery charge and maintain battery functionality.

CPS01G

All columns are equipped with latest generation lithium-ion batteries, meaning

the table can be used without being plugged in for long durations. The battery

status is displayed on the hand control as shown in the table opposite.

To extend the working life of the batteries, we recommend the following:

•

Do not leave them permanently charging (connected)

•

Charge batteries systematically when the indicator on the screen of the hand

control is red

•

Avoid the deep discharge to prevent degradation of battery life time

•

Carry out a preventive maintenance (a control of batteries each year)

When charge is less than 8%, all movements are prohibited. A full screen red

battery is displayed.

When you connect the charger, you immediately recover normal functioning.

Connecting the table to the mobile charger:

1. Lift up the protection cover of the charger socket and connect

the CPS01G.

2. Connect the power cord to a mains socket.

Note:

For a fixed column equipped with a wall charger, the

connection can be made directly in the floor; in this case no additional connection

is required

6.2 Bluetooth wireless mode

IMPORTANT:

The Bluetooth protocol is a mode currently commonly used for remote communication between electronic devices. However, as European

legislation is not harmonized, it is the responsibility of the hospital to authorise (or not) the use of this mode of communication. Therefore,

please check the internal rules at your facility before using this mode.

When a column is in wired mode (see 6.1), the hand control memorizes its identification so that it can control this column (and any associated tabletop), and only

this column, in Bluetooth mode. If another hand control is connected to this column in wired mode, the table will take its ID and disable recognition of the previous

hand control.

To switch from wired mode to Bluetooth wireless mode, you simply disconnect

the spiral cable from the hand control: the hand control will then operate

autonomously on its internal battery.

Bluetooth mode can be identiﬁed by:

internal battery charge status

Internal battery discharged:

When the internal battery is out of charge, a red pictogram appears on the

screen.

The hand control then needs to be recharged by connecting it to the table

using the spiral cable (wired mode) or to one of the chargers. When the

battery is completely recharged, the pictogram disappears.

No column detected display:

If the Bluetooth connection is lost, or if the table is switched off by mistake (using

the STOP button), the hand control switches off. Check that the blue Bluetooth

LED is lit on the column. If it is not, restart the table using the Bluetooth button

on the backup keyboard

As the Gmax™ Transfer System is a modular design, the head and leg sections can be attached in reverse

in relation to the seat and back sections. The patient can then be in a normal or reverse position on the table.

Although the orientation is automatically recognized by the sections mounted on the table, it is always possible to manually

select it with the patient orientation button which reverse the orientation to keep the right selected movement.

Every time the table is reconfigured, ensure that it corresponds to the selected patient orientation.

IMPORTANT:

The use of a pre-programmed cycle requires careful monitoring of the table movements during the movement of the various sections.

For this reason, it is recommended that you use this function during the initial set-up without a patient on the table to save time.

The user memories may have been erased or changed by somebody else, so it is the user’s responsibility to ensure that the desired position

is in fact that shown on the screen before using the function

6.5 ALS (Auto Limit Sensors)

Special case of ALS operation split legs section

Split leg mode is set as the default and takes into account the most restrictive cases.

Thus, it is possible to disable the ALS using “STOP ALS” to continue the movement of one motorized articulation of a leg rest.

Right leg lowered

IMPORTANT:

When the ALS mode is disabled,

the user must look out for

potential collisions between

the sections. ALS mode will be

automatically reactivated when

the configuration of the table is

back to normal.

The electronic sensors and associated software help to avoid the motorized sections colliding with each other or the floor. When a

potential collision is detected during a movement, the movement is stopped, the hand control vibrates and the screen displays the

potential collision in red. It is therefore necessary to correct the position following the screen display, to reach the final position required.

As some parts of the leg and head sections are moved manually, their positions are not detected by the sensors: they must be carefully monitored during movements.

1. Push the 2 lock buttons, which will stay unlocked;

the side indicators will be on red position.

2. Tilt the headrest up 20° to be able to unlock

the 2 hooks

3. Lift the headrest and remove from the hooks

Operating the tabletop (Mounting / demounting extensions)

The tabletop is equipped with a G-LOCK locking system. It is compact, easy to use and secure. With G-LOCK, an extension is automatically locked in when it is

inserted. To remove the extension, simply press the buttons under the articulations.

For convenience, it is preferable to attach and remove the extensions when the table is in horizontal position with the pads removed.

8. TRANSFER FUNCTION

8.1 General information

A Gmax™ transfer system consists of a column, transfer trolley, removable

tabletop and specialized extensions with mechanical articulations that can

be mounted on either side of the tabletop depending on the desired surgical

position.

This multiplicity of possible conﬁgurations should not mean that the essential

rule for transfer in and out is forgotten: the patient must be centred over

the column. Although the tabletop/column and tabletop/trolley “V” interface

is very tolerant in position, it is always better to get as close as possible.

A basic approach to locating the centre of gravity “G” of a patient lying in a

supine position is to ﬁnd his or her navel

Trolley “V” interface

Tabletop “V” interface

with control

Patient’s navel Column “V” interface

Two trolleys are available to move the tabletops of the Gmax™ Transfer

System: the GCARFX, without position adjustment, and the GCARHT, with

Trend and height adjustment. Both trolleys have superb manoeuvrability and

can be inserted around the column from either side with a free access of

100°.

For the transfer, the GCARHT trolley must be adjusted to the right height and

must be horizontal. This can be checked easily by pressing the button on the

trolley: green=OK, red=horizontal positioning to be corrected.

The 4 red pins for moving the tabletop + column assembly must be pushed

in.

100°

IMPORTANT:

The transfer trolleys are used to carry patients but also

to move the transportable columns with the tabletop.

The 4 red pins should only be removed when the trolley is empty,

meaning the tabletop is already on the column.

When a trolley is introduced around the column, this limits all trolley and

tabletop movements to avoid collisions between them.

The up/down buttons on the hand control are neutralized

On the Gmax hand control, the functions of the “bring to horizontal” and

Automatic Transfer keys are identiﬁed:

• The “bring to horizontal” function consists of levelling without sliding or

raising the tabletop and its extensions

• The Automatic Transfer feature consists of moving the tabletop into a

position compatible with transferring the patient, since a patient may, for

example, be transferred into a seated position (max. 30° for the backrest

and -10° for the leg sections). This feature includes slide and height but not

bringing the tabletop to horizontal.

So, in order to transfer ﬂat, the two functions will need to be used sequentially.
