Definitions

  • This invention relates to a handle for high frequency electrodes, particularly for use in high frequency surgery which is provided with built-in switches for operating a high frequency generator so as to change its outgoing energy, its frequency and the like.
  • Handles have mechanical switch contacts which are actuated by push bottoms or tumbler switches. Handles are also known wherein the rotation of a mounted sleeve with inserted slip rings provides the operation of the generator.
  • An object of the present invention is to eliminate these drawbacks and to provide a device of the described type of simplified construction and yet of higher operational efficiency.
  • magneton or in a handle portion constructed as a slide It is also advantageous to apply controlling springs to the slide in such manner that it can be shifted linearly from a predetermined zero position to the operating positions and to arrange the operation of the high frequency generator so that when the magnet is shifted over the contact elements the generator can be switched on at the same time.
  • operating switches are preferably used contact elements embedded in protective mass, so-called reed contacts.
  • FIG. I is a side view of a handle constructed in accordance with the present invention, parts being shown in section.
  • FIG. 2 is a sectional plan view.
  • the drawing shows a handle having a casing l and a high frequency conductor having the shape of a thin narrow strip 2.
  • the conductor is located in the casing and it connects a high frequency cable 3 with a high frequency electrode 5 partially enclosed in a metal box 4.
  • a plastic protecting plate 6 is firmly connected with the casing land is connected directly over the high frequency conductor 2.
  • Two shifted reed contacts 7 and 8 are cast into the plastic plate 6.
  • the contacts 7 and 8 actuate the high frequency generator through the actuating lines 9 and 10 as well as the high frequency cable 2 serving as the common return conduit for the lines, in such manner that when the contact 7 is closed the high frequency generator is switched, for example,
  • the selection between the cutting operation and the coagulation operation takes place by a permanent magnet 12 mounted in a slide 11.
  • the slide 11 is moved in the direction of the arrow 13 up to a stop 14 of a guide 15 against the force of a spring 16, then the permanent magnet 12 will be placed directly over the contact 8 and will close this contact.
  • a handle for said electrodes comprising a casing having a box for retaining said electrodes, high frequency conducting means connecting said electrodes with said generator, switching means, and actuating lines connecting said switching means with said generator for changing its output values, said switching means comprising two reed contacts for separately switching said generator to different output values and a slide actuated magnet biased to assume a zero position between said reed contacts and movable from said zero position to actuate any one of said contacts.
  • a handle in accordance with claim 1, comprising a protecting plate carried by said casing, said reed con tacts being embedded in said protecting plate.
  • said high frequency conducting means comprise a common electrical return conduit for said actuating lines.
