SECTION 1 1. DESCRIPTION

1.1 GENERAL This section contains the purpose, use, and capabilities of the PerFect TCS II (Tissue Contouring System) and attachments. Descriptions and illustrations of the unit's physical characteristics, including control and indicator functions and locations, are provided. Equipment performance specifications are also included.

1.2 INTRODUCTION The PerFect TCS II (Figure 1-1) is a monopolar electrosurgical unit designed to cut tissue and seal small blood vessels in dental procedures. The unit's solid state circuitry generates a high frequency alternating current which is applied to tissue in the operating field by a sheathed electrode (handpiece). The resultant heat generated performs the desired clinical function. The PerFect TCS II provides two different operating modes. Cut mode and Coag mode, with variable intensity level settings for each. Activation of the electrode sheath is accomplished by use of the unit's footswitch. PerFect TCS II Catalog No. S8230CE operates from 230VAC and has a continental European pattern AC plug. PerFect TCS II catalog numbers S8230UK and S8230CT are identical with the exception of the AC plugs which have UK and Chinese designs respectively. PerFect TCS II catalog number S8115 operates from a 115VAC main and is provided with a cord and plug for the US. PerFect TCS II catalog number S8100 operates from a 100VAC main and is provided with a cord and plug for Japan. PerFect TCS II Catalog No. S8240 operates from a 240VAC main and is provided with a cord and plug for Australia.

1.3 DESCRIPTION (See Figure 1-1)

A Physical The PerFect TCS II is a lightweight portable unit consisting of a main body and attached footswitch, as well as the PerFect TCS II Handpiece System and a dispersive electrode. The chassis is housed in the main body and supports the unit's PC board, transformer, and fuse assemblies. The main body front cover provides the POWER, ALARM, CUT and COAG indicator lights and the CUT/COAG intensity control. Located at the rear of the main body alongside the IEC power connector is the power on/off switch. At the right-hand side of the main body are the PerFect TCS II

1-5

Handpiece System connector and dispersive electrode connector. At the left-hand side of the main body is the footswitch cable. At the rear of the main body is the IEC-320 AC power inlet connector.

B Attachments (1) PerFect TCS II Handpiece System - The PerFect Handpiece

System consists of a Cord Assembly, S6008CE, and assorted electrode sheaths, which are used to perform the actual clinical procedures. The Cord Assembly connecting plug mates with a connector on the right side of the main body. The PerFect TCS II is supplied with three assorted PerFect TCS II Electrode Sheaths (additional electrode sheaths are also available). The tip of each electrode sheath is designed to perform a specific clinical function. Instructions for assembly of electrode sheath to cord assembly are provided in the PerFect TCS II Handpiece System packaging.

1-6

Catalog numbers and descriptions of PerFect TCS II Electrode Sheaths are as follows:

Supplied:

S-6011A - 45 Degree Coagulate Ball S-6012A - 45 Degree Straight Knife S-6015A - 45 Degree Long Loop

Optional:

S-6013A - 45 Degree Tapered Knife S-6014A - Straight Round Loop S-6016A - Straight Long Loop S-6017A 90 Diamond Loop S-6018A - AP 1

(2) Dispersive Electrode (indifferent plate, return electrode, neutral electrode) Catalog number S213 The dispersive electrode provides an RF return path for electrosurge current. This reduces the environmental paths of close-by grounded metal (such as power lines, plumbing, or structural steel). The dispersive electrode is capacitively coupled to the subject by placement preferably against the clothed patient's upper back, contacting the maximum possible area. The dispersive electrode plate is electrically insulated and is equipped with a cable and connecting plug which mates with a connector on the right side of the main body. The dispersive electrode is interlocked to the unit such that if it is disconnected or defective the unit will not generate an RF output and will indicate an alarm.

(3) Footswitch The footswitch is designed for floor placement and is waterproof

to IP68. Pressing the footswitch activates the unit. Releasing the footswitch will deactivate the unit. The footswitch is equipped with a cable attached to the left-hand side of the main body.

C Controls and Indicators (See Figure 1-2)

(1) Power On/Off Switch Power is applied to the PerFect TCS II when the power switch is set to the I position. To turn power off, set the power switch to the 0 position.

1-7

(2) POWER Indicator The green POWER indicator illuminates when the power on/off switch is set to the on position with the unit attached to the AC power mains.

(3) CUT ACTIVE Indicator The yellow ACTIVE indicator illuminates when power is on, the intensity control is set to greater than 1 toward the right (CUT) and the footswitch is pressed.

(4) COAG ACTIVE Indicator The blue ACTIVE indicator illuminates when power is on, the intensity control is set to greater than 1 toward the left (COAG) and the footswitch is pressed.

(5) ALARM Indicator The red ALARM indicator illuminates when power is on and the dispersive electrode is not connected or is defective.

(6) Audible indicator A speaker on the left side of the unit produces a tone when the footswitch is pressed. If the dispersive electrode is not connected or is defective, the tone will be a warbling sound indicating an alarm. In this condition no output will be generated.

(7) CUT/COAG Intensity Control This control is used to select the Cut or Coagulate mode, and the intensity level of the selected mode. The control is in a minimum power position when aligned with number "1," The clinical functions performed by each mode are as follows:

a) CUT Cutting Tissue. Rotating the control knob to the right of the center ("0") position activates the CUT mode, The intensity level increases as the control knob is moved further to the right.

b) COAG Sealing tissue and controlling bleeding. Rotating the control knob to the left of the center ("0") position activates the COAG mode. The intensity level increases as the control knob is moved further to the left.

SECTION 3 3. MAINTENANCE

3.1 GENERAL This section provides both block diagram and detailed schematic descriptions of the PerFect TCS II circuit operation. Test procedures, a troubleshooting chart, disassembly, and assembly instructions are also provided. Refer to the PerFect TCS II Owners Guide for instructions for use.

3.2 BLOCK DIAGRAM DISCUSSION The PerFect TCS II consists of seven functional circuits; power supply, high power regulator, modulator, keying circuit, oscillator/driver, output stage and audio generator (see Figure 3-1). The power supply circuit provides +40 volt full-wave rectified DC power to the high power regulator circuit and +12 volts and +5V DC regulated power to each low power circuit. The high power regulator provides regulation of the +40 volt DC output of the power supply circuit. The output of the regulator circuit consists of a DC level of from 19 to 24 volts, which is used to power the output stage. The modulator circuit provides square-wave modulation to the keying circuit when the CUT/COAG intensity control is placed in the COAG position. When the footswitch is pressed while in the COAG mode, the keying circuit provides the COAG drive modulated signal to the driver section of the oscillator/driver function. When the footswitch is pressed with the CUT/COAG intensity control in the CUT position, the keying circuit routes the CUT drive unmodulated signal to the driver circuit. The oscillator generates the 3.68 MHz nominal frequency for both CUT and COAG modes. The output stage provides the drive and impedance matching to the handpiece. The audio generator produces the output activation tone and alarm.

(1) Step-down isolation power transformer T3 supplies approximately 28 volts RMS to bridge rectifier BR1 and filter capacitor C1. This circuit provides +40 volts DC filtered power to the high power regulator section comprised of Q4, Q6, and U6(B).

(2) The secondary windings of transformer T3 are configured as center-tapped to provide current for the low power +12 volt regulator, U2. The +12 volt supply is used for low voltage/low power circuitry and is also used as a voltage reference in the regulatory section. An additional supply voltage of +5 volts is provided by regulator U11 and C52 for the oscillator and frequency divider circuits.

B High Power Regulator The high power regulator circuit consists of Q4, Q6, U6B, R5, R30, and associated components. The junction of R5 and R30 provides a fixed reference voltage of approximately +7 volts DC for the non-inverting input (pin 6) of open-collector comparator U6B.

Feedback action through R8 adjusts operation so that the inverting input of U6B at pin 5 matches the reference voltage at pin 6.

CUT/COAG intensity control RCONTROL is a variable potentiometer that is configured so that maximum resistance to ground occurs when the control is at the center detent position ("0" position on the front panel). Conversely, minimum resistance is obtained when intensity knob is either at full left (COAG) or full right (CUT) positions.

Integrated circuit U6B switches current source transistor Q6 off when the output voltage at Q4 collector is greater than required, thereby reducing conductivity of pass transistor Q4. Conversely, U6B switches current source transistor Q6 on when the output voltage is lower than required, increasing the conductivity of Q4 in order in increase the output voltage.

With the current and voltage at the CUT/COAG intensity control calculated for maximum and minimum resistance, a maximum stabilized output voltage of +25 volts DC is possible at the drain of Q4, and a minimum stabilized voltage of + 18 volts DC will be maintained.

3-25

Transistor Q3 is normally ON to provide keying voltage at the R21 and R22 junction. If regulator transistor Q4 should become shorted, the power output will be higher than expected. To prevent this undesirable condition, transistor Q3 will lose forward bias and keying voltage will not be available due to a lack of Q3 collector current in R21 and R22.

This regulator stabilizes the RF output power against line voltage variations and provides variable output power by use of the CUT/COAG intensity control, RCONTROL.

C Modulator Integrated circuit U1B is a comparator with an open-collector transistor output. The output switches from a low resistance to a high resistance state when the + (non-inverting) input becomes more positive than the - (inverting) input. This occurs when CUT/COAG intensity control RCONTROL is moved away from the center position towards the left (COAG) position. When U1B goes to a high resistance state, Schmitt Trigger U5F which is configured as an astable multivibrator, provides a pulsed output (at pin 12) with a time constant determined by R13, R16, C2, and C31.

(1) Cut Mode When CUT/COAG intensity control RCONTROL is placed in the CUT region, the output of U1B at pin 7 goes to a logic low, discharging capacitors C2 and C31. When the discharging voltage at capacitor C31 reaches the low level trip point input to U5F, the output at pin 12 goes to a logic high. Astable multivibrator U5F is disabled and with diode D3 back-biased while in the Cut Mode, no modulation (i.e. Coag) is possible (refer to the keying circuit description for more details).

(2) Coag Mode When CUT/COAG intensity control RCONTROL is in the COAG region, the output of U1B goes to a high resistance state, permitting the charging of capacitors C2 and C31 with the current from U5F via R16 and R13. When the charging voltage reaches the high level trip point input to U5F, the output of U5F goes to a logic low state. When this occurs, capacitors C2 and C31 are discharged through resistors R16 and R13. When the voltage at capacitor C31 reaches the low level trip point input to U5F, the output of U5F goes to a logic high level. This pulsed output will continue to occur as long as the CUT/COAG intensity control is in the COAG region (refer to the keying circuit description for further details).

3-26

Comparator U1B is used to detect which mode CUT/COAG intensity control RCONTROL is in. This is performed by comparing the relative polarity of the input at pin 5 with the input at pin 6. Diode D3 prevents a logic high at U5F pin 12 from switching on keying transistor Q10 and makes U5F an active-low output function. Since the oscillating action at U5F pin 12 provides both logic high and low levels when the CUT/COAG intensity control is in the COAG region, the modulating frequency will be impressed on the gate of keying transistor Q10.

D Keying Circuit Driver transistors Q7 and Q8 are enabled when their common sources are grounded by Q10 switching on. Q10 is the keying transistor and is operated from the gate formed by diodes D3, D4, D5, and D6. Transistor Q10 is switched ON when all four diodes are non-conducting. If any one diode is in a conductive state, Q10 is switched OFF. There are two possible keying modes of operation. The first is with CUT/COAG intensity control RCONTROL in the CUT region. The second keying condition is with the control in the COAG region. The keying of each mode is controlled by activation of the footswitch. Comparator U6A (pin 1) serves to disable keying when the control is rotated to the "0" marking when in Cut or Coag Mode. U6A (pin 1) goes low when the control is positioned at the "0" marking and diverts keying voltage from Q10 gate. This action makes the R.F. output zero when the control is in this region. When the control is at a setting of "1" or higher, U6 (pin 1) goes to an open-collector condition and D6 cannot divert keying voltage enabling CUT or COAG.

(1) Cut Mode When CUT/COAG intensity control RCONTROL is in the CUT region, modulator U5F is disabled and its output is at logic high, which back-biases D3. No modulation is possible in the CUT mode. With the footswitch not activated, current does not flow through the LED input of optical isolator U10. The inputs to U5A are then at a logic high level (via pull-up resistor R26). This drives the output of U5A to a low level. Diode D5 diversion of the keying voltage dominates Q10 gate. No keying is possible, even though D6 is back-biased and D3 is back-biased when the control is in the CUT position. When the footswitch is activated, current flows through the LED input of U10. A ground potential is then placed at the

3-27

input of U5A through the optical isolator, U10, driving the output of U5A to a logic high. This logic high voltage back-biases D5, removing the diversion of keying voltage from the gate of Q10. Transistor Q10 is now ON and Q7 and Q8 driver current can flow to produce excitation for CUT MODE R.F. output.

(2) Coag Mode When CUT/COAG intensity control RCONTROL is in the COAG position and the footswitch is pressed, D5 is back-biased while D3 is alternating ON/OFF with the modulation frequency of U5F. Q10 switches LOW/HIGH at the astable multivibrator rate, thus modulating driver transistors Q7 and Q8 to produce excitation for COAG MODE R.F. output.

E Oscillator/Driver/Output Stage Crystal oscillator, U12, generates a digital 5V signal at 7.3728 MHz applied to the clock input of U4. Dual 'D' type flip-flop U4 is configured as a binary divider, resulting in a 3.68 MHz output frequency. The two phases of the 3.68 MHz output of the divider are buffered by the two sections of U3. This signal is constantly present at driver gates Q7 and Q8, however, driver current cannot flow until the common sources are grounded by keying transistor Q10. Both the driver and output stages operate as class C, push-pull circuits. Output current flows only when the driver is enabled by footswitch activation. Output transformer T2 provides impedance matching to the handpiece output circuit components, including the handpiece cable capacitance.

F Indicators The PerFect TCS II incorporates visual and audible indicators. The visual indicators are a green POWER LED controlled by R37. It is lighted anytime +12VDC is available which is when AC power is on. A yellow CUT LED indicator is controlled by U1A which senses cut mode and drives the Q2 switch through the U5B inverter and by Q10 which gates output power. The yellow LED is lighted when cut mode output is active. A blue COAG LED indicator is controlled by U1A which senses coagulate mode and drives the Q1 switch and by Q10 which gates output power. The blue LED is lighted when coagulate mode is active. A red ALARM LED indicator will light if the dispersive electrode is not connected or if it is defective. The red LED is driven by Q5 which is controlled by the U9 optical

3-28

isolator through the U5C inverter. The U9 optical isolator senses continuity in the dispersive electrode circuit. An audible indicator generates a 400Hz tone when the footswitch is pressed. An alarm tone will sound if the dispersive electrode is not connected or if it is defective. The tone signal is generated by U7B and amplified by speaker driver U8. When an alarm signal is required, U7A causes the tone to warble.

G Dispersive Electrode Interlock The dispersive electrode integrity is tested by running a small current through it and verifying continuity. An isolated power supply PW1 generates 5VDC which produces a current through the dispersive electrode and through the LED of optical isolator U9. When U9 fails to sense the current through the dispersive electrode, inverter U5C enables the red LED. It also switches Q14 off enabling U7A to generate the frequency switching signal to U7B through Q12 and C41. This results in a warbling tone from U7B.

dispersive electrode and line cord as shown in Figure 3.3. (2) Set line input voltage to the nominal value of AC appropriate for

the model being tested. (3) Switch the power switch to on (|). Verify the green POWER

indicator illuminates. (4) With the output control knob set to 0 press the footswitch and

adjust the sound level by adjusting R38 to read 4.5Vp-p across the speaker terminals on J4.

(5) Disconnect the Dispersive Electrode. Verify the red ALARM indicator illuminates.

Dispersive Electrode and line cord as shown in Figure 3.3. (2) Set line input voltage to the nominal value of AC appropriate for

the model being tested. (3) Turn on power to the unit. Verify the green POWER indicator

3-31

D Tuning Adjustment (1) Connect unit under test as shown in Figure 3.6. Ensure line

voltage is set to the nominal AC value appropriate for the model being tested. Be sure the oscilloscope probe is properly compensated to obtain correct readings. Apply power.


(3) Press footswitch and verify that oscilloscope reading is 513 25 volts p-p or that the ammeter reading is 303 13 mA.

(4) If the reading is out of tolerance, adjust ferrite tuning screw in L2 with a non-metallic tool to obtain the required reading.
