Abstract
A bipolar endoscopic device is provided having a detachable power cord with a plug capable of forming a sealed connection with the endoscopic device. The plug is connected at a back face of a movable guide member of the endoscopic device and can be oriented in different orientations to accommodate different operators. The detachable plug forms a sealed connection with the endoscopic device so that the electrosurgical connection cannot be short-circuited by the outside environment such as a saline irrigation fluid.
Claims29
An electrosurgical instrument, comprising:
- an electrode assembly extending along an axis having a working end and a proximal end, and
- a guide block mounted on the electrosurgical instrument and connected to the electrode assembly for movement along the axis, the guide block having a first opening through which the electrode assembly extends and a second opening coaxial with the first opening for receiving a portion of an electrical connector to establish electrical contact with the electrode assembly.
An electrosurgical instrument assembly, comprising;
- an electrode assembly extending along an axis having a working end and a proximal end,
- a guide block mounted on the electrosurgical instrument and connected to the electrode assembly for movement along the axis having an opening coaxial with the electrode assembly, and
- a detachable electrical connector connected to the guide block through the opening therein to establish electrical contact with the electrode assembly.
An electrosurgical instrument, comprising:
- a working element having a guide block for receiving an end of an electrical assembly through a first opening in a front face and for receiving an electrical plug through a second opening in a back face, the second opening being substantially coaxial with the first opening.
An electrosurgical instrument assembly, comprising;
- a working element having a guide block having a first opening in a front face for receiving an end of an electrical assembly and a second opening in a back face for receiving an electrical connector, the second opening being substantially coaxial with the first opening, and
- a detachable electrical connector connected to the guide block through the second opening, the second opening being constructed and arranged to receive the electrical connector in plural positions.
A method of manufacturing an electrosurgical instrument, comprising the steps of:
- providing an electrode assembly extending along an axis having a working end and a proximal end,
- providing a guide block mounted on the electrosurgical instrument and connected to the electrode assembly for movement along the axis having an opening and a channel to accept the proximal end of the electrode assembly, and
- providing a detachable electrical connector connected to the guide block through the opening therein to establish electrical contact with the electrode assembly.
A method of using an electrosurgical instrument, comprising the steps of:
- providing an electrode assembly extending along an axis having a working end and a proximal end,
- providing a guide block mounted on the electrosurgical instrument and connected to the electrode assembly for movement along the axis having an opening and a channel to accept the proximal end of the electrode assembly, and
- providing a detachable electrical connector connected to the guide block through the opening therein to establish electrical contact with the electrode assembly.
