INTRODUCTION

SECTION 1

Gyrus Medical Ltd, Gyrus Medical Inc and Gyrus ACMI Inc are referred to as Gyrus ACMI in this user manual. This user’s manual will familiarise you with the controls and output functions available from your Superpulse System and instruct you on its proper use. 1A.

Overview of the SuperPulse System An endoscope is an instrument routinely employed to visualise and access the interior of various body cavities for the purposes of both diagnostic and surgical procedures. The endoscope is inserted through a natural body opening, such as the cervical canal or urethra. The instrument commonly includes one or more integral working channels for the passage of surgical instruments, as well as conduits for the passage of gas or liquid required to distend the body cavity. Commonly referred to as ‘underwater surgery’, liquid distension is usually the preferred method in urological endoscopy. Electrosurgery is a familiar tool widely employed in urological endoscopy to perform transurethral prostatectomy (TURP), resection of bladder tumours and cystodiathermy. Based on similar principles, the PlasmaKinetic technology exploits the electrical conductive properties of fluid used to distend the operative site, requiring the standard non-electrolyte irrigation fluids used during conventional TURP to be replaced by normal saline. By adjusting power in microseconds two tissue effect modes can be produced. In the first mode, an ionised plasma corona is created over the active zone of a tissue treatment electrode. Tissue entering the intense kinetic energy of the corona is instantly reduced to its constituent elements and simply washed away in the irrigation fluid. The low thermal mass of the plasma prevents collateral tissue damage adjacent to the application site. In the second mode, rapid, predictable and controlled elevations in tissue temperature can be produced to ablate tissue or seal blood vessels. The SuperPulse mode of operation enables very rapid formation of the plasma enabling easier and more rapid resection of tissue.

1B.

Comparison with Conventional Electrosurgery Conventional bipolar electrosurgery requires that both ‘poles’ of the electrode contact tissue to complete the electrical circuit and produce a tissue effect. Typically, these electrodes do not operate effectively while immersed in a conductive irrigating solution such as normal saline. The Gyrus ACMI SuperPulse Endourology System utilises the fact that saline is electrically conductive to control an ionised plasma around the active tip when electrosurgical current is applied. Essential to this design is the proximity of the return electrode to the active electrode in an AxipolarTM configuration. The fact that the two poles of the circuit are only a few millimetres apart means that current flows only through the irrigant or through the tissue to be vaporised. This localised current flow preserves the recognised safety features of conventional bipolar electrosurgery. Similarly, this arrangement avoids many of the problems commonly encountered when using bipolar electrosurgery: orientation of the electrode to tissue, visualisation of the working tip, tissue sticking and limited power delivery. The intense concentration of electrosurgical energy delivered by the technology offers instantaneous vaporisation of tissue. This effect can be achieved with monopolar electrosurgery but at very high power levels and only in the presence of a non-electrolyte irrigating solution, both aspects of which have recognised complications and safety concerns. Furthermore, the deep tissue heating of monopolar arrangements which occurs during tissue vaporisation causes a progressive deterioration in efficiency over the period of the procedure. The PlasmaKinetic technology overcomes this problem and provides a repeatable tissue effect throughout the procedure. In order for the system to produce this effect, the SuperPulse Generator has integral feedback systems to both initiate and sustain the plasma corona around the active electrode.

INTRODUCTION

SECTION 1

The instruments can only operate within a saline medium. The size of the working tip geometry determines the amount of power needed to ensure optimal performance. To simplify set-up the SuperPulse Generator will automatically select a default power and mode setting according to the instrument type. Power and mode adjustments can be performed by the front panel buttons with the selected output shown on the user display. Instruments are supplied in a sterile, single use format and connect to the SuperPulse Generator via a limited re-use connector cable. Activation of the electrosurgical current is by means of a footswitch, attached via the back panel. Activation is inhibited by safety circuitry until both instrument and connector cable have been properly coupled to the SuperPulse Generator. An audible alarm will sound whenever electrosurgical energy is being output. Diagnostic circuits within the SuperPulse Generator continuously monitor system performance. Any detected faults are indicated as symbols on the user display in conjunction with the illumination of the front panel warning symbol. 1C.

Indications for Use The SuperPulse Endourology System is an electrosurgical system used in conjunction with the PlasmaKinetic Resectoscope or urological endoscopes with 5Fr. or larger working channels, for correction of soft tissue pathologies encountered during endoscopic surgery performed on the lower urinary tract.

1D.

Contraindications for Use The use of this device is contraindicated in patients with the following conditions:   

Carcinoma of the bladder or prostate without tissue diagnosis. Patients with urinary tract infection. Patients with incipient renal failure.

It is advisable to monitor the input and output volumes of the irrigation fluid in all patients but especially those with cardiovascular insufficiency or poor renal function. Patients with Pacemakers Use with caution in the presence of internal or external pacemakers. Interference from an electrosurgical current can cause a pacemaker to enter an asynchronous mode or can block the pacemaker effect entirely. For further information, consult the pacemaker manufacturer or hospital Cardiology Department. 1E.

System Description The SuperPulse Endourology System (figure 1.1) is designed for resectoscopic and endoscopic urological procedures performed on the lower urinary tract. A typical system comprises the following items:   

A SuperPulse Generator A footswitch Re-usable 3m connector cable

When used with a PlasmaKinetic Resectoscope  A PlasmaKinetic PK Plasma-V or PK Plasma-Sect or PK SuperSect/Loop instrument (figure1.2) When used with a suitable urological endoscope (e.g. a cystoscope)  A PlasmaKinetic PK Plasma-Cise or PK Plasma-Cut instrument (figure 1.3)

Intermittent Sheath)

Fig 1.1 The instruments are available in two forms. The Resectoscope Instruments (figure 1.2) are designed to be used in conjunction with the PlasmaKinetic Resectoscope. This resectoscope is uniquely designed to accept the instrument which is connected directly to the connector cable rather than to the resectoscope. Typical use of these types of instruments would be in the surgical treatment of benign prostatic hyperplasia. The cystoscope Instruments (figure 1.3) are intended for insertion through the working channel of any standard, commercially available urological endoscope with a 5Fr. or larger working channel. Typical use of these instruments would be for the desiccation and vaporisation of recurrent bladder tumours. Instruments are designed to provide either vaporisation or desiccation of tissue, using the yellow and blue pedals respectively, of the dual footswitch. The vaporization is achieved with “SuperPulse” (SP) mode or “PlasmaKinetic” (PK) modes, depending on instrument type. Desiccation uses the Desiccated (DES) mode. A third mode is also available, the ThermoKineticTM mode (TS or T).

PATIENT AND OPERATING ROOM SAFETY

SECTION 2

For the purposes of safety procedures and despite the absence of a conventional return pad, the Gyrus ACMI SuperPulse Endourology System should still be treated as a high power electrosurgical device. The safe and effective use of electrosurgery depends to a large degree upon factors and variables solely under the control of the operator. There is no substitute for good surgical technique and properly trained operating room staff. It is important that the operating instructions supplied with this or any electrosurgical equipment be read, and understood, and followed. Electrosurgery has been employed safely in numerous procedures. Before starting any surgical procedure the physician should be familiar with the medical literature, complications and hazards of electrosurgery in that procedure. 2A.

WARNING

Do not wrap accessory cords around metal objects. This may induce currents that could lead to injury to the patient or surgical personnel.

WARNING

Fire Hazard: Do not place active accessories near or in contact with flammable materials (such as gauze or surgical drapes). Electrosurgical accessories which are activated or hot from use can cause a fire.

Endoscopic Procedures WARNING

As visualisation may be impaired during endoscopy for a number of reasons, be particularly alert to these potential hazards: 

Ensure the tip of the instrument is visible before activation.



The instrument tip may remain hot enough to cause burns after the electrosurgical current is deactivated.



Inadvertent activation or movement of activated instruments outside of the field of vision may result in injury to the patient.



Localised burns to the patient or physician may result from electrical currents carried through conductive objects. Electrical current may be generated in conductive objects by direct contact with the active instrument, or by the active or return instrument being in close proximity to the conductive object whilst activated.



Carefully insert and withdraw active instruments from sheaths and working channels to avoid the possibility of damage to the devices and/or injury to the patient.



Only activate during intermittent or preferably continuous flow irrigation to ensure good visualisation and cooling of the instrument tip between activations.

NOTE

Output mode selection can only be performed with an instrument and connector cable attached to the generator. The range of modes available will depend on the type of Gyrus ACMI PK instrument being used.

NOTE

If the Mode / Menu button is quickly pressed and released the generator enters a menu based configuration state, pressing and holding the Mode / Menu button at any time exits this state.

NOTE

The PK output is not available for some PK instruments. The lower left hand portion of the display remains blank in this case.

Mode Selection using Gyrus ACMI PK/SP Instruments - There are three PlasmaKinetic Modes shown as PK1, PK2 and PK3, which produce a tissue effect increasing from PK1 to PK3 (PK3 delivers power more effectively to higher impedance tissue than PK1). Two of the ThermoKinetic outputs available, shown as T1 and T2, continuously switch between a PlasmaKinetic and Desiccate output during activation. These ThermoKinetic outputs will provide a greater degree of hemostasis during tissue cutting compared to a PK setting. Three VP mode levels and the desiccate (DES) are available. VP1 is optimal for low impedance tissue, VP2 for intermediate impedance tissue and VP3 for higher impedance tissue or larger diameter instruments. The frequency of pulses in VP mode will also vary depending on the type of instrument attached: generally, the larger the tissue contact area, the slower the pulses. DES provides a conventional continuous bipolar output. For instruments that support the SuperPulse waveform the PK modes are replaced by SP modes SP1, SP2, and SP3, producing an increasing tissue effect from SP1 to SP3. The SuperPulse modes provide high-energy pulses promoting rapid generation of the plasma corona around the active electrode. Once the plasma corona is established the output reverts to a continuous wave. The SP equivalents of the T1 and T2 ThermoKinetic outputs, TS1 and TS2 rely on selective modulation of the SP2 SuperPulse waveform, to provide a higher crest factor and therefore increased hemostasis. The waveforms associated with the blue and yellow pedals can be individually assigned. To change the waveform press the Mode / Menu button until the option to change the waveform required is seen on the display (yellow pedal waveforms appear on the LHS and blue pedal waveforms on the RHS).

Only one socket can deliver RF at any one time. When the generator is switched on from the Standby state, it initially operates an automatic socket selection mechanism, and assists primary connection by activating whichever socket first has an instrument attached. The instrument connected to the active socket is indicated on the display. Thereafter socket selection can only be altered manually, by pressing the black mode footswitch, ensuring that the surgeon always has control over which instrument is activated.

GENERAL INFORMATION

SECTION 4 Generator Switch On/Off

The mains power On/Off rocker switch is located on the top left of the rear panel (viewed from front). The Generator is switched on by pressing the side marked l. The generator will display the Serial number of the generator, then the internal tests are performed then the green LED below the Mode / Menu button will come on continuously, and then flash after a short time. The generator is then in Idle state. The generator display will dim after a period of 30 minutes of not being used and will automatically enter Standby state if it is not used for a period of four hours. It is advisable to switch off the Generator whenever it is not in use for any extended period, by using the rear panel switch. The side marked “0” should be pressed to do this. To enable use of the generator the Standby / On button must be pressed and the generator will then enter the Idle state if no instrument is fitted, or the Ready state if an instrument is fitted. If an instrument is present at switch on then the user has to accept the default powers, by pressing the Mode / Menu button when prompted. 4C.

SuperPulse Generator Indicators, Set-up and Malfunction Displays Volume Adjustment - The activation tone volume can be adjusted between minimum and maximum using the up control of the desiccate (blue) power control. Depress and release the Mode / Menu button until the symbol “SELECT VOLUME” appears (Fig. 4.6). Press and release the Mode / Menu button once more to accept the setting.
