ELECTROSURGICAL PENCIL

摘要

An electrosurgical pencil adapted to receive an electrode controllable by an electrical signal for performing surgical operations. This pencil includes a housing, a circuit, and switch that is activatable from outside the housing for closing the circuit. The housing receives the electrode. The circuit is a flexible circuit and is positioned such that it is in direct contact with the electrode when the electrode is received in the housing.

主权项

1. An electrosurgical pencil having an electrode controllable by an electrical signal for performing surgical operations, comprising:
a housing that includes receiving means for receiving an electrode, a suction channel extending along the length of the housing, a circuit for providing an electrical connection to the electrode, switching means adapted to be activated from outside the housing for closing the circuit to operate the electrode, and at least one extension piece adapted to be positioned onto the housing for extending the electrode that is received in the receiving means, the extension piece comprising conducting means in electrical association between the circuit and the electrode, wherein the extension piece comprises a tubular member surrounding the conducting means and is adapted to be positioned onto the housing or onto another extension piece.
