result in danger or failure and may void any warranty that may apply.

CAUTION: The AutoSonix™ ULTRA SHEARS™ instruments, Ball Probe and Hook Probe single use instruments are provided STERILE and

are intended for use in a SINGLE procedure only. DISCARD AFTER USE. DO NOT RESTERILIZE.

WARNING: DO NOT ENCLOSE THE GENERATOR HOUSING IN A BAG, OR DRAPE COVERING OVER it WHILE IN OPERATION. AIRFLOW

MUST CIRCULATE THROUGH UNIT DURING USE IN ORDER FOR PROPER COOLING OF ELECTRONIC COMPONENTS.

CAUTION: Do not place generator on towel, foam or other soft surface since the material may block air vents located on the bottom of

the generator. Blocking these vents may cause generator to overheat and malfunction or create a shock hazard.

WARNING: PLUGGING GENERATOR UNIT INTO SOCKET WHICH SUPPLIES IMPROPER VOLTAGE MAY CAUSE GENERATOR TO

MALFUNCTION OR TO CREATE A SHOCK OR FIRE HAZARD. BE CERTAIN LINE INPUT VOLTAGE SELECTOR SWITCH IS

PROPERLY ADJUSTED.

WARNING: PROPER SYSTEM GROUNDING CANNOT BE ENSURED UNLESS UNIT IS CONNECTED TO PROPERLY WIRED HOSPITAL

GRADE OUTLET.

CAUTION: The generator should not be turned on until the patient cable has been connected to both the generator and transducer.

Otherwise, damage to the generator may result.

CAUTION: Ensure all connections and mating surfaces are clean and dry before assembly.

WARNING: CARE MUST BE TAKEN NOT TO DAMAGE THE PROBE. DO NOT GOUGE, NICK, SCRATCH, BEND OR KINK PROBES DURING

USE. DISCARD ANY PROBES WHICH SHOW SIGNS OF SUCH DAMAGE.

CAUTION: Do not hold the probe tightly while the power is on. Clamping the probe restricts the longitudinal motion, causing the probe

to heat at that point. Prolonged restriction may cause the probe to break. Restriction may also cause a mechanical limit

condition, causing ultrasonic energy to be inhibited. Undue bending of the probe may do the same. If both these conditions

are relieved, the mechanical limit condition will be cleared.

2 General Information

System Overview

Description of the System (refer to Figure 1)

The AutoSonix™ System is a system of electromechanical components designed to ultrasonically transect and coagulate a broad range of soft

tissue. The system includes a Generator that produces a 55.5 kHz electrical signal and feeds that signal via the patient cable to a piezoelectric

crystal stack mounted in the autoclavable transducer. The crystal stack converts the electrical signal to mechanical vibration at that same

frequency. This ultrasonic vibration is amplified as it traverses the length of the titanium probe within the disposable instrument to levels

which will permit tissue ablation, cauterization or cutting.

Concept and Principles of Operation (refer to Figure 2)

The AutoSonix™ System uses ultrasound, or sound waves, for fragmentation of soft tissues. Unlike standard cutting or electrosurgical

systems, the AutoSonix™ System offers precise control of tissue ablation due to the controlled ultrasonic field generated. This precise control

allows the surgeon to perform traumatic transection and coagulation with minimal disturbance to surrounding tissue structure.

The Generator unit (Power Supply) feeds a 55.5 kHz (55,500 cycles per second) electrical signal to piezoelectric crystals mounted in the

transducer. The active elements of the transducer then vibrate at that same 55.5 kHz frequency. When placed in a liquid, the vibrating ball tip

causes microscopic bubbles to grow and then collapse with great energy intensity, thus causing the tissue directly in front of the Probe to

be liquefied or fragmented. The blade tip allows cutting and coagulation of tissue by causing shearing forces to be developed in the tissue.

These shearing forces separate tissue and heat the surrounding tissue to a level which permits coagulation and sealing of blood vessels,

without the burning associated with electrocautery.

Functional Components of the System (refer to Figures 1 and 2)

Generator (refer to Figure 1)

The Generator supplies a 55.5 kHz electrical signal to the transducer. A feedback circuit tracks frequency changes in the Probe caused by load

and temperature changes, and maintains maximum electrical efficiency at all times.

In addition, the Generator incorporates an automatic gain control which maintains the amplitude selected by the user. As the Probe contacts

an obstruction, the Generator will automatically supply greater power (wattage) to the transducer, thereby keeping the amplitude constant.

Amplitude, which is the distance the Probe moves out from rest and back in each cycle, determines the extent of tissue disruption. The

Generator has a self-limiting feature which prevents damaging overload.

Main power is controlled by the Main Power switch at the back panel of the Generator. Amplitude is controlled by the Amplitude Control

Knob on the front panel of the Generator (with a setting range from 0-5). A Digital Display is provided to allow the clinician to see the

amplitude set from a distance.

A Mechanical Limit Detector detects breakage along the Probe, Transducer failure, or system overload. These faults will activate an indicator

light and an audible alarm.

An Electrical Fault Detector detects a disconnected transducer cable and a short or break in an output circuit. These faults will activate an

indicator light as well as an audible alarm. Both fault alarms will deactivate the ultrasonic output of the generator.

Foot Switch (refer to Figure 1)

Ultrasonic power is controlled by the Ready/Standby switch on the front panel and by a dual Footswitch connected to the rear panel of

the generator. The left Footswitch pedal control turns on the Ultrasonic output to the level set by the front panel control described above.

The right Footswitch pedal turns on the Ultrasonic Output to maximum. This feature allows the clinician to choose rapidly from a cutting or

sealing mode to coagulation mode.

Transducer (refer to Figure 3)

The handle section of the Transducer houses the piezoelectric crystals which transform the electrical energy from the Generator into

mechanical vibration. The Front Driver transmits and amplifies the vibration out of the transducer casing. A Probe is attached to the Front

Driver by an integral mounting stud. This Probe amplifies the motion and provides the debriding surface of the device. As applications

require, various Probe configurations will be used to extend the working length, to provide increased amplification of vibration, or to provide

a cutting surface for fast removal of tissue. The Transducer is attached to the Generator by a 12 foot (3.66 meters) autoclavable patient cable.

Transducer Cable (refer to Figure 1)

The transducer is attached to the generator by a 12 ft (3.66 meters) autoclavable cable. The cable is supplied with the transducer, and utilizes

keyed connectors at both ends. Either end will fit into the transducer or generator. The transducer cable should be replaced at the same

intervals as the transducer.

Cart

An optional rolling cart is available for storage and transport of the AutoSonix™ generator. The cart is supplied fully assembled.

System Components Preparation

CAUTION: The AutoSonix™ ULTRA SHEARS™ instruments, Ball Probe and Hook Probe single use instruments are provided STERILE and

are intended for use in a SINGLE procedure only. DISCARD AFTER USE. DO NOT RESTERILIZE.

NOTE: The AutoSonix™ transducer and single use instruments together are compatible with generators that produce a continuous wave,

series resonance at a frequency between 55kHz and 60kHz, and utilize phase lock loop / VCO frequency control.

The following reusable items must be cleaned and sterilized prior to the procedure in accordance with appropriate protocols as suggested

herein or such other guidelines as may be directed.

Transducer

The transducer and patient cable can be steam sterilized. It is also possible to cover the transducer and patient cable with a sterile plastic bag

during the procedure rather than sterilizing beforehand.

The front panels of the Generator may also be covered with clear sterile plastic covers during the procedure.

WARNING: DO NOT ENCLOSE THE GENERATOR HOUSING IN A BAG, OR DRAPE COVERING OVER it WHILE IN OPERATION. AIRFLOW

MUST CIRCULATE THROUGH UNIT DURING USE IN ORDER FOR PROPER COOLING OF ELECTRONIC COMPONENTS.

Cleaning and Sterilization

Refer to Section 7, Maintenance, for cleaning and sterilization instructions.

System Assembly

Refer to Section 2, General Information, Figures 1 and 3

NOTE: It is recommended that the Generator be positioned on a cart or table outside the sterile field of the Operating Theater. The Generator

must be placed on a smooth, hard surface.

CAUTION: Do not place generator on towel, foam or other soft surface since the material may block air vents located on the bottom of

the generator. Blocking these vents may cause generator to overheat and malfunction or create a shock hazard.

Verify Settings

Verify that the Main Power Switch on the rear panel of the Generator and the Ready/Standby Switch on the front panel of the Generator are

in the OFF position and that the Amplitude Control Knob on the front panel is set at zero (0). Verify that the Line Input Voltage Selector on

rear panel of generator is set to the proper setting for the line voltage to be supplied by the outlet. Plug the female end of the line cord into

the rear of the Generator. Plug other end of line cord into Hospital grade socket receptacle.

WARNING: PLUGGING GENERATOR UNIT INTO SOCKET WHICH SUPPLIES IMPROPER VOLTAGE MAY CAUSE GENERATOR TO MALFUNCTION

OR TO CREATE A SHOCK OR FIRE HAZARD. BE CERTAIN LINE INPUT VOLTAGE SELECTOR SWITCH IS PROPERLY ADJUSTED.

WARNING: PROPER SYSTEM GROUNDING CANNOT BE eNSURED UNLESS UNIT IS CONNECTED TO PROPERLY WIRED HOSPITAL

GRADE OUTLET.

CAUTION: The generator should not be turned on until the patient cable has been connected to both the generator and transducer.

Otherwise, damage to the generator may result.

Footswitch

Attach the plug from the Footswitch into the connector on the rear panel of the Generator. Make certain that connector is fully inserted. Turn

the collar fully clockwise. Position Footswitch on floor in area easily accessible during procedure.

Transducer and Disposables

Transducer and disposables should be assembled on a table top covered with a sterile drape. Only persons authorized to be in sterile field

should assemble these components.

Page 20

High Frequency Patient Cable

Attach one end of high frequency patient cable to output connector on Generator front panel. Line up the dot on the cable connector with

the corresponding dot on the front panel connector. Push the cable connector into place. Assure that the connection snaps into place.

Patient Cable and Transducer

Connect other end of patient cable to the connector at rear of Transducer, using the same procedure as above. Assure that the connection

snaps into place.

CAUTION: Do not hold the probe tightly while the power is on. Clamping the probe restricts the longitudinal motion, causing the probe

to heat at that point. Prolonged restriction may cause the probe to break. Restriction may also cause a mechanical

limit condition, causing ultrasonic energy to be inhibited. Undue bending of the probe may do the same. If both

these conditions are relieved, the mechanical limit condition will be cleared.

The AutoSonix™ System is now ready for system test.

with no visual or audible alarms activated. Running unit for 15 seconds checks Probe for defects and confirms all electrical and mechanical

connections.

Temperature Test

Release Pedal. Gently feel tip of Probe. Probe temperature should not be significantly above ambient temperature, regardless of how long it

was operating. If Probe feels hot at the junction of the Transducer and Probe, retighten with wrenches supplied and retest. If Probe feels hot

at any point along its length, replace Probe and retest.

WARNING: IF PROBE IS CRACKED OR DAMAGED, SURFACE TEMPERATURE CAN BECOME VERY HOT, AND PROBE MAY PRESENT A

BURN HAZARD TO PATIENT OR CLINICIAN IF TOUCHED. EXERCISE CARE IN TESTING AND HANDLING OF PROBES AT ALL

TIMES. PROBES SHOULD BE TESTED FOR TEMPERATURE RISE AT VARIOUS INTERVALS DURING PROCEDURE TO PREVENT

BURNING OF PATIENT DUE TO DAMAGED OR CRACKED PROBE.

WARNING: DO NOT TOUCH PROBE WHILE IT IS ACTIVATED.

Warning: if the probe has been used in a surgical site, do not activate the ultrasonics with the probe in open air

without first wiping the probe length with a sterile wipe to remove any fluids.

AutoSonix™ System is now ready for use.

Causes

Possible causes are: Loose Probe to Transducer connection, Cracked or Damaged Probes, Defective Transducer or Overload condition at

Probe tip.

Reset

To reset Mechanical Limit Alarm, release Footswitch. Depress Footswitch again. If Mechanical Limit Light and Audible Alarm sounds, refer to

Troubleshooting Chart.

CAUTION: Ultrasonic energy is inhibited if excessive physical force is applied to the probe; use only enough force to guide the probe to

the removal site and to advance the probe through the tissue. Do not force the probe; allow the ultrasonic action to

do all tissue cutting or coagulation.

Electrical Fault

Electrical fault light illuminated and steady audible alarm activated.

Causes

Possible causes are: Patient Cable or Transducer disconnected, Faulty Transducer, Cable or Generator, or overheated Probe.

WARNING: IF ELECTRICAL FAULT INDICATOR ILLUMINATES and/or electrical fault alarm sounds, IMMEDIATELY turn power

switch (rear panel of generator) to the off position. REMOVE PROBE FROM surgical site. DO NOT TOUCH

METALLIC PARTS OF Transducer, PROBE OR GENERATOR while fault is indicated.

Cleaning

Cleaning Transducer and Cable

Brushing should be done with antimicrobial and antiviral soap and warm running water. A standard soft bristle cleaning brush may be used

to scrub exterior surfaces of transducer and cable. Rinse all soap residue from interior and exterior of unit under warm running water for a

minimum of 1 minute. Care must be taken to ensure connections are dry prior to use.

CAUTION: Be certain to clear debris from all surfaces by brushing. Failure to do so may hinder sterilization of units.

CAUTION: Do not use ultrasonic cleaners to clean Transducer or probes. Use manual cleaning techniques only.

Drying Components

Dry all components with absorbent towel or paper. Dispose of cloth or paper in accordance with Hospital or Clinic practices for contaminated

wastes.

Cleaning the Generator

With a cloth or absorbent paper moistened with an antimicrobial and antiviral cleaning agent, wipe down the Generator. Clean all surfaces of

bloodstains and obvious signs of contamination. Dispose of cloth or paper with contaminated wastes.

Warning: Examine the transducer and patient cable for obvious signs of damage (cracks, gouges, cuts in cable,

etc.). Remove any items which show signs of damage from service after cleaning and sterilizing. Mark

damaged items clearly to prevent future use before disposal.

CAUTION: Do not immerse the generator. The unit is not sealed against liquids and damage to equipment may result.
