| Formation of an assemblage of electrically conductive components for a new electrosurgical pencil is disclosed, and assembly of those components in a method for automating the manufacture and combination of current carrying metal circuitry and operable switching components in “electrosurgical pencils” which supply current to an active terminal, for application of high frequency or high power electrical current to a surgical site, and control of such current through coaction of the elements of the switch. In manufacture, the design of the switch components allows start-to-finish automated assembly of the switch, in an industry which knows only partially automated assembly, and partial assembly by hand, to create an improved tool for surgical cutting, coagulation, and cauterizing. | ||||||

| A mechanical limiter switch for use in a medical or surgical device has a substantially cylindrically shaped housing with a perimeter and an opening in an axial direction. The housing has a pattern along the perimeter. A spring is mounted in the opening along the axial direction, and is pre-stressed for movement in a radial direction and pre-stressed for movement in the axial direction.

| A foot switch for use in the control of medical apparatus comprises a pedal that is connected to and movably seated on a floor plate of a joint connection, a sensor linked to a switch element, and a repositioning device disposed between the floor plate and the pedal. The repositioning device ensures that an operating force must be applied to the upper surface of the pedal to produce a tilting movement of the pedal out of an initial position into an operating position in which a smaller angle is defined between the floor plate and the pedal than in the initial position and in which the sensor is activated to trigger the output of a switch pulse from the switch element. The improvement of the present invention consists of the combination of the repositioning device and the joint into an elastic joint device. The simplified foot switch is easily disinfected. | ||||||

| An bipolar electrosurgical tool (10) for cauterizing or ablating tissue. The tool has a nose cone (12) which serves as a handle. A conductive shaft (14) extends from the nose cone. A tip assembly (18) with an active electrode (20) is mounted to the shaft. A circuit board (78) is mounted in the nose cone. Conductive traces that forming contact pads (96, 102) are formed on the circuit board. A web (108) formed from a single piece of elastomeric material is seated over the opening in which the printed circuit board is mounted to seal the opening shut. Integrally formed with the web are buttons (116, 118) that are in registration over the contact pads. The buttons can be depressed downwardly towards the contact pads. When a button is so depressed, a conductive landing pad (120) integral with the button closes the connection between the traces that form the contact pad. Thus, the tool of this invention is provided with switches. The circuit board also has two conductive traces (92, 104a) that run in parallel. If there is a leak into the nose cone, a connection is established across these traces and shorts out a resistor (105). The shorting out of this resistor provides a control console (22) with an indication that there is a leak. The electrode is formed from a single piece of tantalum. The electrode has a head formed with a hole (172) trough which fluid flows. The electrode is seated in a sleeve (136b) provided with a through bore (177) in registration with the electrode hole. | ||||||

| An electrosurgical device is provided having at least one elastomeric seal capable of providing bio-contamination and dielectric protection by inhibiting the ingress of fluids and contaminants through the nose and actuator areas. The elastomeric seal is manufactured from a thermoplastic elastomer or resin which while in liquid form is placed within a mold. A housing section having the main circuit components and mechanisms of the electrosurgical device is then placed within the mold. Once the elastomer cures, the elastomeric seal seals the components and mechanisms within the housing partial-section. The elastomeric seal defines a flexible first opening at a distal end of the electrosurgical device to accommodate varying diameters of electrodes or blades connected to the nose area of the electrosurgical device. An actuator seal is also provided on the actuator area of the electrosurgical device to prevent fluids and contaminants from entering the electrosurgical device through the actuator area. Two buttons are insert molded within the actuator seal and are operatively associated with a self-cleaning switching mechanism within the housing section to operate the electrosurgical device between a cutting and coagulating mode. The actuator seal is also manufactured from a thermoplastic elastomer or resin. | ||||||
