Abstract
Systems and methods here include a meniscal allograft with a bone block and a technique for making a desired shape in the bone block to be used to implant in a patient. A clamp and/or jig arrangement are disclosed that are able to secure the tissue and allow three corresponding cuts to the tissue using the clamp as a guide to a saw to obtain the desired shape.
Claims14
A system for preparing a meniscal tissue for implant, comprising:
- a jig with a base, two lower jig arms, and two upper jig arms;
- a clamp with a first block having a first slot and a second block having a second slot, the first block and the second block connected by a threaded screw rod that allows the first block and the second block to be moved closer or farther from one another through corresponding screw threads;
- the jig having three pairs of posts, a first pair of posts located on a top of the two upper jig arms, a second pair of posts located on a middle of the two upper jig arms, and a third pair of posts located on a top of the two lower jig arms,
- wherein the first block and the second block are configured to mount on each of the three pairs of posts by the first slot and the second slot in each of the respective first and second blocks, wherein when the clamp is mounted to one of the three pairs of posts the jig and clamp are configured to guide sawing a meniscal tissue bone block secured in the clamp to obtain a shape that is generally of the same shape as the clamp first block and the second block;
- and
- wherein each of the first block and the second block are configured to secure a bone block and meniscal tissue.
3 more elements
A system for preparing a meniscal tissue for implant, comprising
- a jig and a clamp combination, configured such that the clamp includes two clamp mounting surfaces on each of a first block and a second block, and the jig includes three jig mounting surface post pairs on an upper pair of arms and a lower pair of arms, the two clamp mounting surfaces and the three jig mounting surface post pairs are configured to mate to secure the clamp in each of three positions on the three jig mounting surface post pairs;
- wherein the first block and the second block are connected by a threaded screw, wherein the first block is configured to mount to one of the three jig mounting surface post pairs and the second block is configured to mount to one of the three jig mounting surface post pairs, and wherein the first block and the second block are configured to secure a tissue sample between the first block and the second block.
