Abstract
An electrosurgical forceps includes a first shaft member including a first inner frame. A first jaw member extends distally from the first inner frame. A first outer housing is supported by the first inner frame. The first inner frame includes a first member stamped from sheet metal. A second shaft member includes a second inner frame. A second jaw member extends distally from the second inner frame. A second outer housing is supported by the second inner frame. The second inner frame includes a second member stamped from sheet metal and a rigid filler member disposed on the second member.
Claims17
A forceps, comprising:
- a first shaft member including a first inner frame;
- a second shaft member including a second inner frame and an outer housing surrounding at least a portion of the second inner frame, the second inner frame including a first overhang member extending from an upper end of the second inner frame and a second overhang member extending from a bottom end of the second inner frame, wherein the second shaft member is pivotably connected to the first shaft member at a pivot member;
- a first jaw member positioned distally of the pivot member;
- a second jaw member positioned distally of the pivot member;
- a filler member coupled to the second inner frame between the first and second overhang members such that the first and second overhang members inhibit vertical movement of the filler member;
- and
- a strap member secured to the first and second overhang members to secure the filler member between the strap member and the second inner frame and inhibit lateral movement of the filler member, wherein the first overhang member, the second overhang member, the filler member, and the strap member are at least partially positioned proximally of the pivot member.
A forceps, comprising:
- a first shaft member including a first inner frame;
- a second shaft member including a second inner frame and an outer housing surrounding at least a portion of the second inner frame, the second inner frame including a first overhang member extending from an upper end of the second inner frame and a second overhang member extending from a bottom end of the second inner frame;
- a pivot member pivotably coupling the first and second inner frames to each other, wherein the first overhang member and the second overhang member are positioned proximally of the pivot member;
- a first jaw member positioned distally of the pivot member;
- a second jaw member positioned distally of the pivot member;
- and
- a filler member coupled to the second inner frame between the first and second overhang members and extending from a proximal end disposed on the second inner frame proximal to the pivot member to a distal end disposed distal to the pivot member, wherein the filler member dissipates heat away from the distal end of the filler member toward the proximal end of the filler member.
A forceps, comprising:
- a first shaft member including a first inner frame and a first jaw member extending distally from the first inner frame;
- a second shaft member pivotably coupled to the first shaft member at a pivot member and including a second inner frame, an outer housing surrounding at least a portion of the second inner frame, and a second jaw member extending distally from the second inner frame, the second inner frame including a first overhang member extending laterally from an upper end of the second inner frame and a second overhang member extending laterally from a bottom end of the second inner frame, wherein the first jaw member and the second jaw member are positioned distally of the pivot member and the first overhang member and the second overhang member are positioned proximally of the pivot member;
- a filler member disposed between the first and second overhang members, the filler member configured to dissipate heat away from a distal end portion of the second shaft member toward a proximal end of the filler member;
- and
- a strap member secured to the second inner frame to secure the filler member between the strap member and the second inner frame to inhibit lateral movement of the filler member.
