Abstract
Technologies for securing a tissue pad to a jaw clamp of an energy-based surgical instrument includes a surgical instrument having an end effector. The end effector includes an ultrasonic blade and a jaw clamp. The jaw clamp includes a metallic frame and a tissue pad attached to the metallic frame. The tissue pad of the jaw clamp has a minimum width that is greater than width of the ultrasonic blade. Additionally, the sidewalls of the tissue pad and the metallic frame may be beveled so as to retain the tissue pad in the metallic frame.
Claims20
An end effector of a surgical instrument, the end effector comprising:
- a jaw clamp including a metallic frame and a tissue pad attached to the
- metallic frame, wherein the tissue pad comprises a polytetrafluoroethylene (PTFE) substrate;
- and
- an ultrasonic blade configured to contact the tissue pad of the jaw clamp when the end effector is in a closed position,
- wherein the metallic frame of the jaw clamp includes a pair of metallic sidewalls and each metallic sidewall includes a tab extending longitudinally along the corresponding metallic sidewall, and
- wherein the tissue pad includes a pair of sidewalls and each sidewall includes a slot extending longitudinally along the corresponding sidewall, wherein a minimum width of the tissue pad is defined between the slots of the pair of sidewalls and the minimum width of the tissue pad is greater than a width of the ultrasonic blade.
An end effector of a surgical instrument, the end effector comprising:
- a jaw clamp including a metallic frame;
- and
- tissue pad attached to the metallic frame, wherein the tissue pad comprises a polytetrafluoroethylene (PTFE) substrate;
- and
- wherein the metallic frame of the jaw clamp includes a pair of beveled metallic sidewalls, and
- wherein the tissue pad includes a pair of beveled sidewalls configured to mate with the beveled sidewalls of the metallic frame to retain the tissue pad in the metallic frame.
A surgical instrument comprising:
- and end effector having a jaw clamp and an ultrasonic blade,
- wherein the jaw clamp includes a metallic frame and a tissue pad attached to the metallic frame, and
- wherein the tissue pad of the jaw clamp has a minimum width that is greater than a width of the ultrasonic blade.
