Removable switch electrocautery instruments
First Claim
1. An electrocautery instrument, comprising:
- a conductive member adapted to come into contact with tissue for electrocauterization;
a handle on said conductive member enabling said conductive member to be positioned by surgical personnel;
means for electrically insulating said conductive member from said surgical personnel, said electrical insulating means including enabling means for enabling an electrical connection to said conductive member; and
switch means including at least one electrically conductive spring clamp member releasably attaching said switch means to said handle, said switch means having at least one releasable electrical connection to said conductive member via said spring clamp member and said enabling means, and said switch means including means for electrically connecting said spring clamp member to a source of electrical energy, whereby said switch means may be readily removed from and replaced on said electrocautery instrument.

Abstract
A family of removable switch electrocautery instruments is provided by springably releasably mounting a switch means to an instrument provided with a conductive member adapted to come into contact with living tissue and a handle member. The handle member may be formed of conductive material covered with an insulative layer or the handle member may be comprised of an insulative material. Means are provided on the switch means for making an electrical connection with the conductive member which was adapted to come into contact with the living tissue. Electrical connection between the switch means may be made through one of the springably releasable attachments or it may be made by means of a separate connector element.
