Abstract
An electrosurgical forceps includes first and second shaft members pivotably coupled to one another such that pivoting of the first and second shaft members between spaced-apart and approximated positions pivots jaw members thereof between open and closed positions. A handle of the first shaft member may be moved against a resilient bias of a spring element.

An electrosurgical forceps, comprising:
- a first shaft member having a first jaw member secured to and extending distally from the first shaft member, the first shaft member having a proximal end portion supporting a handle;
- a second shaft member pivotably coupled to the first shaft member and having a second jaw member secured to and extending distally from the second shaft member, the second shaft member having a proximal end portion supporting an activation switch;
- and
- an elongated spring element supported in the proximal end portion of the first shaft member, wherein the handle is configured to flex the elongated spring element and urge the proximal end portion of the first shaft member into engagement with the activation switch, wherein the elongated spring element has a proximal end and a distal end, at least one of the proximal end or the distal end of the elongated spring element is fixed to the first shaft member;
- a first capture member operably engaged to an inner wall of the proximal end portion of the first shaft member, the proximal end of the elongated spring element supported by the capture member;
