Abstract: An electrosurgical tip (10) for the application of electromagnetic energy in either a monopolar or a bipolar circuit through the tissue and the bodily fluids of an animal or human (13) has a metallic electrically and thermally conductive electrode for connection to an electrosurgical generator proximally and for transmission of the electromagnetic electrosurgical energy (12) to the tissue and the bodily fluids of the animal or human (13) distally. A sheath (18) of heat shrinkable fluorinated polymeric substance is an electrical and thermal insulator (14) held about the electrode for preventing the flow of electromagnetic and thermal energy from the metallic electrically and thermally conductive electrode to the tissue and the bodily fluids. A smooth surface of the sheath (18) contacts the tissue and the bodily fluids and has a low surface free energy. Openings (16) through the sheath (18) extend from the electrode to the surface (15) for permitting the passage of energy. A wall (17) of the sheath (18) is of a thickness adequate to space the electrode from substantially any contact with the tissue and isolate heat due to the arcs. A ceramic substance (19) is an electrical and thermal insulator (14) about the conductive electrode for preventing the energy flow. A method of making the tip includes covering the electrode with the insulator, isolating physically the heat generated due to the passage of energy. A method of using the tip places the surface (15) in close proximity to the tissue and the bodily fluids, transmits the electromagnetic energy through the openings (16), allows cleaning tissue and bodily fluids from the surface (15). The use includes first passing energy through openings (16) in a wall (17) of electrical and thermal insulation and application of electromagnetic energy by either a monopolar or a bipolar circuit relative to the tissue and the bodily fluids of an animal or human (13).

Abstract: A device (10) for retrograde hole opening through tissue has a member (11) elongate on an axis with a cross section shaped to insert axially through external tissue. A distal and a proximal end (13) of the member (11) respectively enter the tissue during placement and remain outside the tissue for control (26). A tip (14) at the distal end (12) has a deployable tissue divider (16) with one or more tissue parting elements (17) and each has a splitter (18). The tissue parting elements (17) are located within the cross-sectional dimensions of the member (11) in a storage position and are movable relative to the tip (14) for placement in an exposed position relative to the tip (14) when shifted from storage so that the splitter (18) thereof splits tissue during retrograde extraction along the axis and contact with tissue. Linkage (19) between the proximal end (13) and the deployable tissue divider (16) retains each of the tissue parting elements (17) with its splitter (18) exposed. The deployable tissue divider (16) has an electrode (23) for transmitting radio frequency energy received from the proximal end (13) to at least each splitter (18). A return path (27) completes the circuit to provide an electrosurgical effect during the retrograde extraction. A method of placing the device (10) for retrograde hole opening aligns the axis of the elongate member (11) normal to the outside abdominal wall of the body, places the distal end (12) through the tissue and leaving the proximal end (13) outside of the tissue, deploys the tissue divider (16) having one or more tissue parting elements (17) that are first located in a storage position within the cross section to an exposed position with the splitter (18) of each element positioned to split tissue, moves each element axially while exposed and fixed and splits tissue during extraction from the body cavity.

Abstract: A clamping force mechanism (10) and its method of use with electrosurgery allow a user to seal and/or joint patient's particular vascular tissue; the mechanism is elongate with user and patient ends (14). An actuator (15) is at the user end (13) and the effectors are at the patient end (14). Each effector has a face of an area to contact the particular vascular tissue. A lost motion connection (18) transfers user actuation to the effectors to hold a predetermined clamping force during electrosurgical tissue sealing. A yielding member (19) in the loss motion connection clamps the particular tissue between the faces with a predetermined force. The yielding member (19) is a spring (20), slip clutch (36) or hydraulic coupling possibly near the actuator (15). An active electrode is carried on one end effector and a return electrode (24) contacts the tissue so an electrosurgical energy supply (25) connected thereacross delivers energy therebetween. A feedback circuit (27) responds to parameters of energy delivered to tissue. A temperature sensor (28) on one face and an impedance monitor (29) respond to energy delivered. A control (30) applies energy to held tissue to seal and/or join it. The method transfers user actuation of the effectors with the lost motion connection (18), maintains clamping force while sealing and applying electrosurgical energy to seal and/or join held tissue. Energy is applied to a temperature or an impedance. The method shifts the yielding member (19) so the opposing faces (17) clamp the particular tissue therebetween with the force from the spring (20), via a transfer rod or by the hydraulic coupling or the slip clutch (36) for a range of pressure.

Abstract: A method and assembly for electrically and mechanically connecting one or more flexible conductive members (11), with one or more insulated wires (12) using one or more insulation piercing terminals (13). The flexible conductive member (11) may have one or more electrically conductive layers (14) attached to a pliable backing (15). The insulated wire (12) may have one or more conductors (16). The insulation piercing terminal (13) provides a low impedance electrical connection between the flexible conductive member (11) and the insulated wire (12), while also providing a mechanical connection between the flexible conductive member (11) and the insulated wire (12) which minimizes movement of the insulated wire (12) due to any axial and/or longitudinal forces that may be applied to the insulated wire (12) or the flexible member (11) during manufacturing and use. The insulation piercing terminal (13) combines one or more piercing members (17) with an integral mechanical securing means and an electrical contact for engaging the flexible conductive member (11). The insulation piercing terminals (13), used in this method and assembly, eliminate the need to prepare either the flexible conductive member (11) or the insulated wire (12) prior to assembly. The method and assembly are of particular advantage to medical equipment manufacturers involved in designing and manufacturing flexible electrode type circuits, such as the return electrodes for use with electrosurgical generators or other electrodes or sensors associated with patient monitoring procedures and devices.

Abstract: A laser and electrosurgical system (10) has a handpiece (12) with a proximal and distal end (13) and (14) from which laser radiation (17) and/or electrosurgical energy (18) is selectively or concurrently directed. The ends are along an axis; an electrode extends distally along the axis. Sources of laser and electrosurgical energy (18) are available and controlled. An initiation circuit (25) for the laser selectively delivers it before electrosurgery. Prior delivery to target tissue, the laser creates an ionized conductive pathway for electrosurgery. The combined concurrent application of laser and electrosurgery has a mechanism (27) to selectively distribute energy about the axis. A laser deflecting surface (28) or a beam deflector vibrate relative to the axis. A power switch (30) has levels for laser cut and ionization and/or a delay therebetween for electrosurgical coagulation. A wave guide (34) or an array thereof deliver radiation along the axis. A method has steps of directing selectively and concurrently laser and electrosurgery by aiming the axis, controlling laser and electrosurgical energy (18), delivering laser before electrosurgery, forming an ionized conductive pathway for the electrosurgery, distributing the laser about the axis in a predetermined pattern by deflecting the laser in a predetermined pattern generally along but slightly displaced from the axis to direct electrosurgical energy (18) in a predefined pattern on the patient's (11) target tissue. In another possible approach, there are additional steps of delivering the laser radition (17) as a beam and varying an ionized conductive pathway by refracting or diffracting the laser radiation (17) beam with the mechanism (27) having a beam pattern deflector.

Abstract: An ultrasonic surgical handpiece (10) for surgery on a patient has a handpiece with distal and proximal ends (12) on a housing (13) thereof for manipulation by a surgeon. A vibrator (19) is carried within a hollow (15) inside of the housing (13). A tool (16) extends from the vibrator (19) at the distal end (21) to the distal tip (22) and is tubular with a bore (17) along its axis so axial vibrations at high frequency are transmitted to the distal tip (22). Fluid (27) flows from the distal tip (22) to the vibrator (19), cools the vibrator (19) and connects to a source of suction (24) at the proximal end (12). A flue (25) carried cantilever on the distal end (21) extends about the tool (16) so a space is between the tool (16) and the flue (25) for guiding fluid (27) from the distal end (21) to the distal tip (22). A port located through the tool (16) connects between the space and the bore (17) and is axially positioned near the distal end (21) to collect fluid (27). An inlet (26) on the flue (25) is near the distal end (21) for fluid (27) provided by a supply. The inlet (26) is axial distal of the port and/or may meter fluid (27) to a preset range. The port may be at, near or toward a low stress region of the tool (16). The vibrator (19) is piezo. The port can be diametrically opposed to the inlet (26). Holes (29) may be located through the tool (16) near the distal tip (22) to prevent misting, clogging or dripping of fluid (27). A method of cooling the ultrasonic surgical handpiece (10) has steps that circulate fluid (27) from the inlet (26) to the space and port and pass cooling fluid (27) about the vibrator (19) and to the source of suction (24). A method of making the ultrasonic tool (16) may include having one or more ports (30) through the tool (16) to the bore (17) wherein the ports (30) are at, near or toward low stress regions and allow fluid (27) flow from the space to the bore (17).

Abstract: A monitoring circuit (10) for an electrosurgical generator (11) has active and return output conductors. Voltage, current (24) and the inverse of current (24) picked up inductively are provided to adder circuits for summing the picked up voltage (20) and current (24) and computing the difference of the picked up voltage (20) and the current (24). Root mean square to direct current converters (26 and 28) signal RMS average values of the sum and difference. A microprocessor squares the values and applies them to a formula wherein the sum signals (22) have subtracted therefrom the difference signals (25); the results are divided by four to provide the root mean square of the power applied to the load (12). During desiccation the output is regulated in response to impedance to shut off output. A diagnostic circuit relates impedance load and output response during operation to a look up table or a microprocessor algorithm to calibrate. Feedback modifies the output when the adders determine the power applied to the load (12) in real time. A method has generator output to active and return conductors (14 and 15) and to inductive pick ups (16 and 17) for voltage and current (24), computes sum and differential values (25), changes root mean square to direct currents (24), squares the values and subtracts the differential from the summation, then divides the result finding the root mean square value of the power.

Abstract: An ultrasonic oscillator (46) drives a tool at a set frequency. An amplitude control runs the oscillator (46) to set the vibration level. A frequency regulator joins the amplitude and the oscillator (46). A control feedback loop (49), in the frequency regulator, keeps handpiece linear dynamics. An operational transconductance amplifier (52), in the oscillator (46), governs gain of the loop (49). A circuit (55) connects to the control to retard the rate of current application over time to the amplifier (52). The circuit (55) has switching to either retard the rate or reset for start up. The amplifier (54) is a current output device with current directly proportional to the bias current and input voltage with bias as gain change for the loop (49). The circuit (55) limits the bias to the amplifier (54) to modify frequency response and output current. A capacitor delays application of the bias to the amplifier (54). Replaceable tools of various lengths or shapes positioned along an axis vibrate for surgery at the frequency and a wave length. Tools longer than one wavelength and of configurations tuned to oscillate around the frequency resonate as a function of their material, length and configuration. A flue (17) surrounds the tool and has a hollow elongate semi rigid central body (28) about an axis with a funnel (29), at one end thereof and a nozzle (30), at the other to direct annular irrigant/coolant flow therethrough. The funnel (29) and nozzle (30) are resilient. Reinforcing ridges (32), inside the nozzle (30), act to maintain concentricity between the flue (17) and nozzle tip and channel irrigant thereabout.
