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

摘要： A method of making a return pad for an electrosurgical system comprises the following steps. A first step includes die cutting an electrically conductive foil on a backing using a rotary press to create a foil blank. A second step includes peeling the conductive foil from around the blank, and leaving the blank on its backing. A third step includes layering electrically conductive gel together with the die cut foil to form a layered sheet. A fourth step includes blanking the return pad from the layered sheet using a rotary die. The rotary die has cutting edges and a die packing material adjacent to at least a portion of the edges. The die packing material compresses the gel prior to cutting. The compression is preferably sufficient to cause elastic deformation in the gel so that the gel retracts after being cut. The retraction of the gel leaves a border around the edge of the pad. The border region helps prevent the possibility of the gel coming into electrical contact with an unintended object. One of the advantages of the method of manufacturing disclosed herein is that a continuous rotary process can be used to manufacture electrosurgical return pads. The continuous nature of the process increases the efficiency of the manufacturing operation. The apparatus for using the method is also disclosed.

摘要： An apparatus and method for igniting plasma in a surgical system is disclosed. A corona discharge is generated on a surgical handpiece which is used to ignite a plasma arc for surgical operations. The advantages include greater reliability and repeatability of plasma arc ignition. The apparatus comprises a handpiece incorporating an active electrode, a passage for ionizable gas, and a corona return electrode. The corona return electrode has a terminus on the holder and near the distal end of the holder. The corona return electrode is electrically connected to the return path of the electrosurgical generator. A non-uniform electric field is generated between the active electrode and the corona return electrode of sufficient strength so that a corona is formed near the active electrode. A separate return electrode may be on the patient, or the apparatus may be configured for bipolar electrosurgical operation by carrying the return electrode on the handpiece. A dielectric material separates the active electrode and the corona return electrode. There is substantially capacitive coupling between the active electrode and the corona return electrode. There is substantially resistive coupling between the active electrode and the return electrode.

摘要： An insulating switch base with a top, bottom and an edge has openings through the top and one edge for a conductor. A conductive switch lead frame has proximal ends with insulation displacement connectors bent in the openings. A resilient member on the frame has a moveable contact and is conductively associated with a connector. A contoured arm on the frame is distal of, but conductive with, another connector. The arm is spaced from the resilient member as an open contact capable of momentary engagement. A frangible area on each frame is between the resilient member and the arm. Recesses in the top support retain the frame. A slot and barbs on each connector receive one conductor securely in an opening after aligned installation in an opening, seating of the frame in its recess and severing the area over a passage in the base. A membrane attaches over the frame and a molding is applied about the membrane leaving the resilient member open.

摘要： A flow monitor including an optical sensing chamber and an electronic controller which allows determination of exact drop volumes and flow rates. In one embodiment, the flow monitor forms part of a gravity fed volumetric controller in an IV system. In another embodiment, the flow monitor takes the form of a urinary output monitor in a urine collection system. Basically, the flow monitor comprises a microcontroller which responds to parametric information fed into the system through a keyboard and variable information detected by a novel drop diameter detector. The electronic controller, in response to the parametric and variable information being fed into it, is able to determine the precise volume of IV solution or urine passing through the respective systems. In the volumetric controller, the microcontroller causes a linear actuator to control the diameter of a flexible pinch tube found in the IV system. Under one mode of operation, the diameter of the pinch tube is regulated to control drop size. In another mode of operation, the diameter of the tube is regulated to control the time interval between drops. By selectively combining the two modes of operation, a precise volume of IV fluid may be administered to a patient. Also forming part of the system are audible and visual alarms to alert the user to any malfunctions in need of correction.
