Abstract
Electrosurgical devices and methods associated therewith are provided. The electrosurgical devices include a proximal end, a shaft extending distally from the proximal end, and an end effector operatively coupled to a distal end of the shaft. The shaft consists of a monolithic outer tube, and a single inner guide disposed within the monolithic outer tube and extending a length thereof. The end effector includes a pair of jaws configured to grasp tissue and to receive a blade from the shaft to transect the grasped tissue.
Claims18
An electrosurgical device, comprising:
- a proximal end;
- a shaft extending distally from the proximal end, the shaft consisting of:
- a monolithic outer tube, and
- a single inner guide disposed within the monolithic outer tube and extending a length thereof;
- an outer guide coupled to the shaft and the proximal end, the outer guide being configured to minimize unwanted motion between the proximal end and the shaft;
- and
- an end effector operatively coupled to a distal end of the shaft, the end effector comprising a pair of jaws configured to grasp tissue and to receive a blade from the shaft to transect the grasped tissue.
An electrosurgical device, comprising:
- a proximal end;
- a shaft extending distally from the proximal end and being secured to the proximal end via an outer guide including an outer guide base, an outer cover, and an outer guide clip configured to couple the outer guide to the shaft, the shaft consisting of:
- a monolithic outer tube, and
- a single inner guide disposed within the outer tube;
- and
- an end effector operatively coupled to a distal end of the shaft, the end effector comprising a pair of jaws configured to grasp tissue,
- wherein the outer guide is configured to minimize user independent motion between the proximal end and the shaft.
