Abstract
Abstract A handle for high frequency electrodes, particularly for use in high frequency surgery has built-in switches for operating a high frequency generator so as to change its outgoing energy, frequency etc. The device is particularly characterized in that contact elements depending from a magnetic field are used as the operating switches and that a permanent magnet is located in the handle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
100 words
For use with a high frequency surgery generator, high frequency surgery electrodes, a handle for said electrodes, said handle 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.
Claim 2
Dependent Claim
100 words
For use with a high frequency surgery generator, high frequency surgery electrodes, a handle for said electrodes, said handle 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.
Claim 3
Dependent Claim
100 words
For use with a high frequency surgery generator, high frequency surgery electrodes, a handle for said electrodes, said handle 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.
Claim 4
Dependent Claim
100 words
