Description

Adjustable flexible bone-to-bone fixing device and implantation mechanism Technical Field The invention relates to the technical field of medical instruments, in particular to an adjustable flexible bone-to-bone fixing device and an implantation mechanism. Background The tibiofibular and ulna combination is a combination of support and connection commonly found in the human body, for example, the tibiofibular inferior tibiofibular joint is composed of a distal tibiofibular joint and an inferior tibiofibular ligament complex, and the surgical treatment method for tibiofibular joint ligament injury is often to stabilize the fibula and tibia in a relatively proper position so that the ligament is gradually restored, and the currently common method is to drive the tibia through the fibula by one or more cortical screws to obtain a relatively stable rigid fixation mode, but the shearing movement and rotation of the fibula relative to the tibia are prevented by adopting the cortical screws for rigid fixation, and the screw driving position is not well controlled in actual operation, and the risk of post-operation screw fatigue fracture is large. The prior art discloses a device, which is characterized in that a belt loop titanium plate is respectively placed on the outer side of a fibula and the inner side of a tibia, and a suture is used as a flexible fixing mode of a fixture before the tibiofibular joint ligament is restored. However, in the above-described manner, although the method of fixing with two belt loops of titanium plate solves most of the problems of rigid fixation, it is required to penetrate the tibia and fibula so that the removal amount of bone increases. Disclosure of Invention The invention aims to provide an adjustable flexible bone-to-bone fixing device and an implantation mechanism, and aims to solve the problem of large bone removal caused by the fact that a fibula and a tibia are fixed by two belt loop titanium plates in the prior art.
