The invention relates to a tunable with
posterior cruciate ligament reconstruction
tibia positioning device on a
dissection force line axis extension cord. The tunable
posterior cruciate ligament reconstruction
tibia positioning device includes a positioning arm and a
handle, the rear end of the positioning arm is fixedly connected with the front end of the
handle, a sliding block is arranged on the
handle, a locking device for locking the sliding block is arranged on the sliding block, one end of a support rod is fixedly connected with the sliding block, the other end of the support rod is fixedly connected with a guide block, and a guide hole is formed in the guide block; a positioning tip at the front end of the positioning arm inclines to the left or the right, and the axis of the guide hole penetrates through the positioning tip. According to the tunable
posterior cruciate ligament reconstruction
tibia positioning device on the
dissection force line axis extension cord, the positioning tip inclines to the exterior, and therefore the positioning tip can be located on a slope groove on the posterior
cruciate ligament dissection force line axis extension cord behind the proximaltibia; meanwhile, the positioning tip deforms along the slope groove, passes through a posterior
cruciate ligament stop and arrives at the inner side of the fossa intercondyloidea, an
acute angle formed by a transplant and a tibia tunnel is successfully converted into two obtuse angles, pressure on the tibia tunnel and pressure on part of the transplant are reduced, abrasion caused by the edge ofthe tibia tunnel to the transplant is reduced, and a killer turn effect is reduced.
