    6. PRINCIPLES OF OPERATION 6.1 INTRODUCTION The OPTIKON ASSISTANT is a state of the art system designed for both cataract extraction and retinal surgery. The use of a multiple microprocessor architecture combined with some Large Scale Integration circuits (LSI), allows concentrating high technology and top performances in a small and compact unit.
  • Page 32 Assistant Service Manual OPTIKON 2000 analogical inputs go to the microprocessor (which is capable of up to eight analog inputs and over forty digital I/O lines) and all the digital and analog control outputs are generated by the same microprocessor. Software establishes the links.

    2. Sheet 3/5 contains a series of optocouplers designed to electrically separate the signal circuitry of the microprocessor from the power Darlington transistors that drive the various valves of the ASSISTANT. Sheet 4/5 contains: - The electronic driver of the peristaltic pump. The pump is driven by a 12Vdc motor connected to J12.

  • Page 36: Graphic User Interface

    - A watch dog circuit to monitor the microprocessor activity. In case of microprocessor failure, this watch dog disables outputs of U6 and U16 TTL latches that control system outputs, putting the ASSISTANT in a safe state. - A serial DAC (MAX5250) that generates the dc voltages to control the pressure preset of the air injection tamponade system and the preset of Ultrasound power.
  • Page 37 Assistant Service Manual OPTIKON 2000 The relevant connector is J7. The Control Board and the GUI exchanges data using a proprietary eight bit protocol. The correctness of data flow is continuously monitored by both the Control Board software and the GUI software, a rotating logo in the lower part of the user screen ensures that the two software are communicating properly.

The board contains both the U/S driver and the Diathermy driver, they share the same adjustable power supply and they are both controlled by the same microprocessor (NEC’s 78F0078).
  • Page 45 Assistant Service Manual OPTIKON 2000 controls the VCO, to dynamically correct possible changes, due to changes in the load, of the handpiece resonating frequency. Piezo handpiece is connected to J1 card connector and is driven by a sinusoidal voltage of variable frequency and amplitude. The frequency of the voltage supplied to the handpiece is automatically adjusted by the control circuit in order to match the resonating frequency of the acoustic vibrator.
  • Page 46 Assistant Service Manual OPTIKON 2000 U/S Amplifier Section The sinusoidal voltage supplied to the handpiece is picked up at the secondary winding of L1 transformer and filtered through L3 and C9. L1 primary winding is the load of the U/S amplifier, consisting of the two power MOSFET (Q2 and Q3), operated by the U5 driver.
  • Page 47 Assistant Service Manual OPTIKON 2000 Amplitude control section and Minimal Stress circuitry Amplitude of sinusoidal signal applied to handpiece is proportional to the direct voltage present at the central tap of primary winding of L1 transformer. It is the output of switching regulator made up by U18,CR2,L2,C4.
  • Page 48 Assistant Service Manual OPTIKON 2000 Diathermy driver section (Sheet 2/2) Bipolar diathermy driver generates a voltage of an approximately sinusoidal form, at a fixed frequency of 2 MHz. The maximum output power is 7W on 450 Ohm load. The output of diathermy if floating (insulated from any other voltage or ground), current can flow only between the two opposite poles.
  • Page 49 Assistant Service Manual OPTIKON 2000 If a malfunction is detected (i.e. U/S or Diathermy are emitted when not required or a wrong power level), The Control Board stops any power emission driving U/S_SIG and DIA_SIG to a low level. These signal lines are connected to J5.

A window pops up in the middle of the LCD giving full explanation of the warning or error, if operation can continue, an OK button appears on the window.
  • Page 87 Err 02: Low input pressure This message is generated by the closure of the pressure switch (Fig.4a, ref.5). The ASSISTANT should be supplied with a pressure in the 5-8 bar range (72.5-116PSI). If the input pressure goes outside this range (less than 4.5 or more than 9bar, 65.29-130.6PSI)), Err 2 is delivered.
  • Page 88 Err 26: Diath enable/reading failure, Err 27: Diathermy enable failure The ASSISTANT tests its capability to start/stop diathermy emission both with the standard software enable/disable and with the safety hardware disable. If a malfunction is found Err26 or Err27 are generated.
