Problems solved by technology

However, bone knives and hammers are not special tools after all, which makes the above-mentioned traditional bone extraction methods easy to cause irregularities in the bone body, often resulting in poor matching between the bone body and the pre-opened counterbore hole at the site to be transpl

Embodiment Construction

[0030] For ease of understanding, combined here Figure 1-7 , the concrete structure and working mode of the present invention are further described as follows:

[0031] The main structure of the present invention is as Figure 1-3 and Figure 5-7 As shown, it includes a sampling tube 10 and an annular edge 20 arranged at the bottom end of the sampling tube 10 . During work, the annular blade 20 is responsible for cutting the bone body a2, and the placement cavity formed by the sampling tube 10 and the annular blade 20 is used to accommodate the cut bone body a2, while the groove 11 at one side of the sampling tube 10 is The tendon a1 on the bone body a2 is drawn out to protect the tendon a1.

[0032] In actual operation, after selecting the tendon-bone position to be taken, first dissect the width and length of the tendon a1 to be transplanted, and then pass the tendon a1 through the bottom of the annular blade 20 and pull it out from the groove 11. When the annular blade...

Abstract

The invention belongs to the field of auxiliary tools for orthopedic surgery, and particularly relates to a tendon-bone transplantation assist device. The device comprises a sampling tube, an annular blade for cutting a bone body is coaxially arranged at a bottom tube opening of the sampling tube, and an annular cavity of the annular blade and a tube cavity of the sampling tube are communicated with each other to jointly form a placement cavity for temporarily storing the bone body; a groove communicated with the placing cavity is radially formed in the pipe wall of the sampling pipe in a penetrating manner; and the groove length direction of the groove extends upwards along the axial direction of the sampling pipe so as to form an empty groove area for a tendon on a bone body to pass through. The device can realize a rapid bone taking function, so that the operation efficiency is effectively improved, and the healing time and the healing effect of a tendon-bone connection point are ensured.

Description

technical field [0001] The invention belongs to the field of orthopedic operation aids, in particular to a tendon-bone transplantation aid. Background technique [0002] Tendon and ligament injuries usually involve the tendon-bone junction, and the healing time and healing effect of the tendon-bone junction are key factors affecting the surgical repair and reconstruction of tendon and ligament. The promotion of tendon-bone healing is mainly accomplished in two ways. One is to change the local environment between tendon-bone, increase the connection between the two, promote the migration of cells in bone to the graft, and provide a more active tissue for tendon-bone healing. The second is to promote the healing of the affected area by adding tissues with high osseointegration activity, such as tendon-bone grafting, to the affected area. When performing tendon-bone transplantation, the transplant target is given priority to other intact parts of the patient, and the composite...
