Abstract
The invention discloses a kind of for ligament or the fixation device of tendon, which includes: cylindrical column core and the epitheca that is nested in outside the column core；The top of the column core is equipped with groove, and the bottom end of the column core is equipped with square groove, and the cylinder is equipped with multiple open cell channels along the column core arrangement substantially symmetrical about its central axis, is equipped with slideway on the outer surface at every two adjacent open cell channels interval；The bottom end of the epitheca is equipped with circular pedestal, and the upper surface of the pedestal is equipped with the branched structure that setting is matched with the slideway.The invention has the benefit that the rubbing crack of implantation of ligament object can be effectively reduced, and knuckle synovia is effectively prevent to penetrate into osseous tunnel, to promote the circumferential healing of graft/osseous tunnel contact position.With certain osteoconductive and/or osteoinductive, it can make in the implantation material degradation in vivo absorption process, bone tissue regeneration substitution ultimately forms complete ligament-knitting.
Description
Technical field
The present invention relates to medical implantation instrument field, in particular to a kind of for ligament or the fixation device of tendon
And fixing means.
Background technique
The anatomical position as locating for anterior cruciate ligament (ACL) will likely be held in sports or other activities
By high active force.With the raising of sports level and the complication of acrobatics and tumblings, the fracture of ACL have become it is most commonly seen and
Ligament injury the most serious, it is commonplace that ACL fracture occurs for player.
A variety of method for reconstructing have been had been developed that for ACL damage at present, including autologous reconstitution, allosome are rebuild and people
There is inevitable drawback in work ligament reconstructive, these method for reconstructing, such as pain, transmission, immune response, ligament
Loose and mechanical mismatches etc..The long-time stability in the joint after reconstruction depend heavily on graft fixed form whether
It is capable of providing permanently effective fixed effect.Common fixed form such as extrusion screw, suspention steel plate etc. usually cannot be in bone roads
Nearly articular side is formed effective fixed and is blocked, so as to cause " rain brush effect ", " bungee jumping effect " and lead to the abrasion of graft
Expansion and joint fluid with bone road directly pour into bone road cause it is slow at graft-knitting, therefore bring ACL repair the phase
Long-term effect is bad or even rebuilds the consequence of failure.
Summary of the invention
To solve the above problems, the purpose of the present invention is to provide a kind of fixation devices and fixation for ligament or tendon
Method, can mitigate the pain of tendon or implantation of ligament, and the stability of flexible implant displacement can be improved.
