Wireless force sensor on a distal portion of a surgical instrument and method
First Claim
1. An apparatus comprising:
- a surgical instrument comprising;
a distal end including a jaw portion, the jaw portion having an external surface including a contact surface and a non-contact surface, the contact surface extending between a first lengthwise edge and a second lengthwise edge, the non-contact surface extending around the jaw portion from the first lengthwise edge to the second lengthwise edge, the non-contact surface having a recess extending from the non-contact surface into the jaw portion anda force sensor mounted in the recess of the non-contact surface, the force sensor comprising;
a wireless package comprising a surface acoustic wave strain sensor and a folded antenna, the folded antenna being electrically coupled to the surface acoustic wave strain sensor, the surface acoustic wave strain sensor including identification information of said surgical instrument.

Abstract
A surgical instrument includes a distal portion. A force sensor is operatively mounted on the distal portion. The force sensor includes a wireless package, which wirelessly provides (1) identification information of the surgical instrument and (2) strain data related to the distal portion. A surgical end effector includes a jaw and the distal portion is on a non-contact portion of the jaw. The wireless package includes a surface acoustic wave strain sensor with identification information. The wireless package also includes a small folded antenna electrically coupled to the surface acoustic wave strain sensor with identification information. The identification information includes an identification of a type of surgical instrument and unique identification of the specific surgical instrument in the type of surgical instrument.
