Load sensor for bone graft
First Claim
Patent Images
1. A load sensor adapted to be inserted between two bones of a mammal system for sensing a stress exerted on said load sensor comprising:
- a body;
a load transducer mounted in said body for transducing a strain occurring thereon when said body is subjected to said stress into an electronic signal adapted to be transmitted to an analyzer for analyzing said stress exerted on said load sensor; and
a length-adjusting means mounted on one end of said body for adjusting a length of said load sensor to make said load sensor firmly fixed between said two bones.

Abstract
A load sensor inserted between two bones for sensing a stress exerted on the load sensor includes a body, and a load transducer mounted in the body for transducing a strain thereof resulting from the stress into an electronic signal. Such load sensor can detect a stress exerted on a bone graft bone and/or the interaction of the bone graft and spine implant to improve curative effects and increase the successful rate of a bone graft operation.
