Electrosurgical Instrument Having a Thumb Lever and Related System and Method of Use
First Claim
1. An electrosurgical instrument, comprising:
- a housing having a movable thumb handle rotatable about a first axis;
a driveshaft having a first end and a second end, the driveshaft coupled at a first end thereof to the thumb handle and longitudinally rotatable about the first axis;
a shaft coupled to the housing, the shaft rotatable about a second axis defined longitudinally therethrough and having an end effector disposed at a distal end thereof; and
a drive assembly configured to couple a second end of the driveshaft and a proximal end of the rotatable shaft, wherein a rotation of the driveshaft is translated into a rotation of the rotatable shaft.

Abstract
An electrosurgical instrument and system and method for performing electrosurgery therewith is disclosed. The electrosurgical system includes an electrosurgical generator adapted to supply electrosurgical energy to tissue. The electrosurgical system includes an electrosurgical instrument that provides a shaft, such as a laparoscopic shaft, having at the distal end thereof an end effector. The end effector may include without limitation a pair of movable jaws adapted to perform tissue fusion and/or vessel sealing. The electrosurgical instrument includes a movable thumb lever in operable communication with the shaft to enable the surgeon to rotate the shaft in an ergonomic, single-handed manner.

17. A method of performing electrosurgery, comprising the steps of:
-
providing an electrosurgical module configured to generate electrosurgical energy; providing an electrosurgical instrument comprising; a housing having a movable thumb handle rotatable about a first axis; a driveshaft having a first end and a second end, the driveshaft coupled at a first end thereof to the thumb handle and longitudinally rotatable about the first axis; a shaft coupled to the housing, the shaft rotatable about a second axis defined longitudinally therethrough and having an end effector disposed at a distal end thereof, wherein the end effector is configured to deliver electrosurgical energy to tissue; and a drive assembly configured to couple a second end of the driveshaft and a proximal end of the rotatable shaft, wherein a rotation of the driveshaft is translated into a rotation of the rotatable shaft; providing a cable assembly configured to operably couple the electrosurgical module and the electrosurgical instrument; actuating the movable thumb handle to rotate the end effector; and applying electrosurgical energy to tissue. - View Dependent Claims (18, 19)
