Abstract: An electrosurgical tubular trocar system (10) has a hollow tube (13) substantially longer than its diameter. The tube (13) is shaped for insertion in a direction generally along its axis through tissue of a human or animal body. Distal and proximal ends (17 and 18) on the tube (13) enter and remain outside the tissue, respectively. A tip (19) on the distal end (17) punctures tissue of a human or animal. An insulating portion (20) of high dielectric material extends along the tube (13) between the distal and proximal ends (17 and 18). An electrode (14) on the insulating portion (20) extends from the proximal end (18) to the tip (19) to transmit radio frequency energy. A tip point (19) at an acute angle to the axis lessens the initial force necessary for entry of the tube (13). The return path (16) is a conductor (23) on the insulating portion (20) for bipolar cutting across a gap (25). An alternate system may have the return path (16) as a conductive pad (15) in contact with the tissue as a monopolar circuit. The tube (13) may be in fluid communication for flow.

Abstract: An electrosurgical generator (10) is disclosed that includes an exit spark control system. Exit sparking occurs when energy arcs to the patient (13) as the active electrode (12) is withdrawn from the patient (13). A basis for controlling the exit spark is to automatically change the frequency at which the final amplifier is driven whenever the conditions for an exit spark are detected. The change in frequency acts to lower the gain and efficiency in the final amplifier and dissipate energy as heat. The exit spark control system includes a frequency adjustable waveform generator (14) and a logic capability for determining the conditions when exit sparking is likely to occur. Sensors and an algorithm in a microcontroller (16) are preferably required to detect the conditions preceding exit sparking occurrence. It is further preferred that, the algorithm also controls the sequencing of events: first stopping the electrosurgical output to prevent an arc from initiating and then changing the driving frequency appropriately to dissipate excess stored energy. The output waveform may be stopped for only a short time or the surgeon will detect drag while cutting through tissue.

Abstract: A connection of first and second members (11 and 12) wherein each has a body and a connecting end with an inner surface (17) so the second connecting end (19) has an outer surface (20) shaped for telescoping into the inner surface (17) of the first connecting end (16). A shoulder (21) is located on the second member (12) and a groove (22) is in the outer surface (20) of the second connecting end (19). A raised nub (23) on the inner surface (17) of the first connecting end (16) is radially inward to engage the groove (22). An elastomeric gasket (13) is positioned to bear against the shoulder (21) and be compressed between the first and second bodies. An engaging trough (24) in the groove (22) holds the first connecting end (16) against the shoulder (21) with the nub against the groove (22) by the compression force of the gasket (13). An indexing trough (25) in the groove (22) positioned along the groove (22) beyond the engaging trough (24) allows the nub to follow therethrough and slightly compress the gasket (13) thus giving the user a tactile indication that it has been rotated beyond the engaging trough (24). A method for fluid tight attachment of members (11 and 12) of a medical device has steps including the connection of the first and second members (11 and 12) with ends by telescoping the ends. Locating a groove (22) for operating the groove (22) as a cam (14) and locating a raised nub (23) of material on the inner surface (17) of the first connecting end (16) for positioning the raised nub (23) to engage the groove (22) for operating the raised nub (23) as a follower of the cam (14) are steps. Compressing a gasket (13) seal between the first connecting end (16) and the shoulder (21) while making the gasket (13) seal from an elastomeric material is a step. Positioning an engaging trough (24) in the groove (22) to hold the first and second connecting ends (19) against each other is a step. Positioning an indexing trough (25) in the groove (22) so when the nub is rotatably forced past the engaging trough (24) it will further compress the first end against the gasket (13) is a step.

Abstract: In an ESV a control system responds to impedance and temperature as sensed between and at the electrodes (13) during desiccation each of such electrodes being provided separately and independently through a suitable multiplexer with a specifically controlled RF power. An instantaneous impedance monitor senses impedance variations and controls by means of specific derivative sensitive algorithm part of a feedback loop, the output power delivered through each electrode. A further temperature dependent feedback loop power control system is operative in a multiplexed mode in pair with the above impedance feedback system. Such second system uses an array of temperature sensors placed in the immediate proximity of the each tissue contacting electrode, and an appropriate derivative sensitive algorithm. Both systems are operated in a multiplex mode through a first multiplexer. A second multiplexer shifts the output power to the various electrodes independently and separately.

The ultrasonic surgical apparatus (10) is comprised of a handpiece (11) which incorporates a transducer (14) and a surgical tool (16), a source of electrical energy (17), a controller (18), and a switch (19). The apparatus may be operated at two frequencies within the ultrasonic spectrum, where the first frequency (22) is selected at the low end of the spectrum for enhanced tissue cutting performance, and the second frequency (23) is approximately three times higher for enhanced tissue coagulation performance. The two frequencies may be operated selectively or concurrently, and may be independently adjustable as to amplitude. The transducer (14) may be composed of magnetostrictive or piezoelectric elements (20 or 21). The surgeon to set the desired amplitude of the mechanical vibrations. The transducer (14) is mounted within the handpiece (11) at a location that corresponds to a vibration node common to both the first frequency (22) and the second frequency (23). Also claimed is a method for use, including the steps of: developing an ultrasonic resonance at a first frequency (22); developing an ultrasonic resonance at a second frequency (23) which is approximately three times greater than the first frequency (22); resonating an ultrasonic transducer (14) at the first frequency (22) concurrently with the second frequency (23); and supporting the transducer (14) where the nodes of vibration at the first frequency (22) are substantially coincident with the nodes of vibration at the second frequency (23).

Abstract: A constant power control circuit (107) for an electrosurgical generator (101) and a method for maintaining the electrical power output of an electrosurgical generator (101) at a generally constant value throughout a given tissue impedance range are disclosed. The constant power control circuit (107) and the method recognize and use the unique and simple linear characteristics associated with certain electrosurgical generator (101) designs to monitor and control the electrical power output without having to calculate or monitor the actual output power. The constant power control circuit (107) includes a current sampling circuit (115), a linear conversion circuit (117), and a feedback correction circuit (119). The constant power control circuit (107) may also include protection circuitry that prevents the electrosurgical generator (101) from being over-driven during high and/or low impedance loading (121), and reduces the severity of exit sparking by providing a quick response to high impedance indications while nonetheless maintaining increased power levels throughout a preset, nominal impedance range. The constant power control circuit (107) and method may be included as an integral part of the overall electrosurgical generator's (101) circuitry, or may be embodied as a separate unit that connects to, and controls, an electrosurgical generator (101). The constant power control circuit (107) and method may be embodied through a variety of analog and/or digital circuit components or arrangements, including software running on computational and memory circuitry.
