1. Overview
1.1 General description of the Arco-units, MBC-units
The RF-surgery equipment makes the following applications available to the user.
- Cutting in steps 1-54
- Cutting with Blend-function in steps 1-54
- Coagulation modes - Soft4- Force4- Spray4
- Argon inertgas1
- Bipolar Coagulation2,4 - Bipolar Cutting2,3,4
The desired mode is roughly selected on the front panel by 5 pre-select buttons and can
then be fine adjusted by arrow buttons. The desired mode can be activated by footswitch
or fingerswitch at the handpiece.
Application of function fields monopolar4and bipolar2,4 is as follows:
a) If monopolar4-handpieces with fingerswitches are used, an activation of the
bipolar2,4 functions Cutting and Coagulation is possible by means of a double
footswitch. Both function fields are thereby useable. In this case both indicator
fields are active.
b) If monopolar4-handpieces without fingerswitches are used, only one of the function
fields can be activated. The use of both functions with one footswitch is possible,
but in order to switch from one function to the other a manual selection at the
equipment is necessary.
For more detailed description of the control- and indicator-elements see instruction
manual.
The Arco -respectively MBC-units were only meant for the use in general surgery and
gastroentorology. Operations on the heart, eyes and in the brain (neuro-surgery) are not
admissible!!!
This equipment has not been developed for continual operation (constant power-supply
for a longer period). The period for use fulfills the minimum demands for operation of the
EN60601-2-2 (10s load, 30s break).
Before starting operation the supplies of the appropriate handpieces must always be
checked for external damages. Only accessories from the Söring Accessories Order List
are allowed to be applied to the unit. We take no liability for accessories of other
manufacturers.

1.2 Co-operation of units
The equipment contains the following units:
- Electrical components
-Primary power supply unit: transformer, line-filter, power switch and parts
of mains board
-mains board with low-voltage power supply, mains relays and voltage
selector switch
-High-power supply
-Cut -module incl. Interface
-Coagulator-module incl. Interface
-RF-output module incl. Handpiece allocation, PE-monitoring and bipolar
recognition 2,3,4
-Handpiece recognition
-Gas control1
-Synchronization board1
-Front panel (modular design)
-Micro controller (CPU)
-Mechanical components
-Gas system1
The wiring of the modules and their cooperation is shown on the following block diagram
and the voltage-supply plans. Power is connected to the mains power socket, which
contains the mains fuses and a parasitic suppresser filter. Via the mains switch the power
goes to the mains board. This contains a voltage selector and an inrush current limiter (a
resistor, which is short-circuited after approximately 1 second). The mains voltage goes
to the primary winding of the transformer. It feeds the low-voltage power supply and via a
separate rectifier bridge and smoothing capacitors the high power supply. These two
units are also placed on the mains board together with a low voltage power supply.
The power supply of the other modules is provided by two different power supplies. The
low-voltage power supply (on mains board) feeds front panel, microprocessor, handpiece
recognition and RF-output module. The high-power part, consisting of coagulator- and
cut-module, is fed by the high-power supply.
The power modules deliver RF-signals to the RF-output module (HFO). Here the RF-
signal first passes through a power measuring device, is then converted to the necessary
output voltage by means of an output transformer and is finally switched to the desired
handpiece by the allocation relay. Furthermore the RF-output module contains checking
circuits for the PE-contact check and a tissue contact detection for the bipolar output.
The handpiece recognition (HSE) delivers information regarding type of connected
handpiece respectively its switch functions to the CPU via the handpiece bus. The
sensing of footswitches is also performed by this module.
The CPU-board (microprocessor) controls the complete sequence of the equipment. It
gets information about the desired mode from the front panel modules via an I2C-bus.The
power modules (high-power supply, cut- and coagulator module) are controlled by a
parallel module control bus. The check of actual voltage of the high-power supply as well
as the status of the power modules is done via the module status bus, which connects
the power modules with the RF-output. This information is transferred from the RF-output
module to the CPU via the status bus.
The relay control, check of delivered output power, status of PE-electrode and tissue
contact recognition on the RF-output module is done via the I2C-bus.
In order to protect the software functions the CPU-board is connected to a
microprocessor watchdog and a voltage monitor on the power supply board.
The control of argon gas flow supplied to the handpiece is performed by the gas control
board located at the CPU-board. Gas control is carried out by the CPU via the I2C-bus.
