Problems solved by technology

[0002] For patients with early unicompartmental degeneration of the knee joint caused by meniscectomy, meniscus allograft transplantation is an alternative treatment method, and it is also the only meniscus reconstruction technique currently used in clinical practice. , especially arthroscopic minimally invasive surgery technology still lacks arthroscopic minimally invasive surgical instruments, therefore, seriously hindering the development and popularization of this technology
[0003] At present, most bone bridge fixation techniques in meniscus transplantation are open surgery or small incision surgery. The surgical trauma is heavy, the operation is difficult, and the technology lacks standardization. So far, the minimally invasive technique of total arthroscopic meniscus transplantation exists One of the difficulties is that there are no standardized surgical instruments for most surgical operations. Doctors can only rely on bare hands and naked eyes to make the shape of the bone groove and the shape of the bone bridge. The size of the two can only be estimated by the naked eye. There is no standardized operation. With the help of instruments, the size and shape of the bone groove and the bone bridge often do not match, so the quality of the mosaic fixation of the two is poor, which not only prolongs the operation time, but also makes it difficult to achieve the best stability of the bone bridge fixation

Embodiment Construction

[0039] The present invention will be further described below in conjunction with accompanying drawing.

[0040] 1. To make a bone bridge on the allogeneic meniscus: First, close to the anterior and posterior corners of the meniscus and use a thin bone knife to remove the excess bone on the side of the meniscus (the outer meniscus should first be close to the anterior and posterior corners of the meniscus to remove the outer bone, and the inner meniscus should be removed first. inner bone). Put the allogeneic meniscus upside down and put it into the meniscus fixation table (1), align the side of the resected bone with the edge of the mold of the bone knife, and use the clamp to firmly fix the bone block connected between the front and rear corners of the allogeneic meniscus from the up, down, left, and right directions. Use a semicircular bone knife (14) with bilateral unequal heights to cut the bone block through the bone knife mold to complete the production of the bone bridg...

Abstract

The invention relates to a meniscus transplanting bone bridge inlaying technology and device and belongs to the field of medical devices. The meniscus transplanting bone bridge inlaying device is composed of a meniscus fixing table (1), a sighting device (2), a guide pin (3), a guide pin sleeve pipe (4), a drill bit sleeve pipe (5), a hollow drill (6), a semicircular bone chisel (7), a socket wrench (8), a drill bit (9) and an allen wrench (10). The meniscus transplanting bone bridge inlaying device is characterized in that a cutting edge is arranged at the left end of the hollow drill (6), a quick change interface is arranged at the right end of the hollow drill (6) and can be connected with a universal quick change handle, the center of the semicircular bone chisel (7) is provided with a through hole, a knife body is semicircular, the head of the semicircular bone chisel (7) is provided with a cutting edge, and the head of the socket wrench (8) is provided with the allen wrench. Under monitoring of an arthroscope, a bone bridge is manufactured, and a bone bridge inlaying operation is performed through small incision of the skin.
