Electrosurgical Handpiece

摘要

An electrosurgical tool includes an electrically powered handpiece with a detachable electrode at one end and a power connection at the other. A mechanism for connecting the detachable electrode to the handpiece includes a keyed electrical connection to power the electrode. The handpiece includes a feedback controller incorporated in the tool to adjust operational characteristics of the electrosurgical tool.

主权项

1. A device for conducting surgical procedures, comprising:
a handpiece main body; an electrical conduit passing through the handpiece main body; an electrode attachment detachably connected to the handpiece main body; a second electrical conduit passing through the electrode attachment that electrically connects to the electrical conduit when the electrode attachment is attached to the handpiece main body, wherein the electrical conduit and second electrical conduit provide an electrical path for passing electrical current to a surgical operative field; a feedback mechanism positioned within the handpiece main body; a feedback electrical path between the electrode attachment and the feedback mechanism; and a key interface connecting the electrode attachment and the handpiece main body, wherein the key interface further comprises a first electrical contact on the handpiece main body and a second electrical contact on the electrode attachment; wherein the key interface aligns the first electrical contact and the second electrical contact to transmit an electrical signal to the feedback mechanism to adjust the operational parameters of the device.
