Technical Field
The invention relates to a fixing nail, in particular to an ankle joint peripheral ligament repair fixing nail, and belongs to the technical field of medical instruments.
Background
Ankle sprains are the most common injuries in athletic activities. Although nearly 80% of ankle sprains are fully recovered, 20% of sprains can develop conditions of mechanical or functional instability and can produce conditions of chronic ankle instability. Chronic ankle instability can lead to persistent pain, decreased recreational activities, and possibly degenerative changes in the early ankle. The majority of ankle injuries involve the lateral ankle ligament complex, which includes the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL)) and the posterior talofibular ligament (PTFL). Most of the injuries of the lateral ligaments are plantar flexion due to external force and ankle inversion due to unstable center of gravity of the body. ATFL is the weakest part of the lateral ankle ligament; therefore, it will be torn often. In fact, in multiple sprained ankle surgeries, two-thirds of the ratio is ATFL tears and one-third involves combined ATFL and CFL tears. Use apart from anterior fibula ligament (ATFL) fracture as an example, staple among the prior art is a screw formula structure, drill hole at the fibula in advance, provide into the way passageway for the staple, then implant screw formula staple from the passageway of going into the way, the screw thread that utilizes the staple periphery wall combines with the fibula, realize the fixed of staple, and rope on the staple is as an organic whole apart from anterior fibula ligament knot with the fracture, accomplish apart from the restoration of anterior fibula ligament, this kind of screw formula staple only relies on self screw thread and fibula combination, because the contact surface between the two is little, and then make the grip strength of staple also receive the limitation, in patient's recovered process, it is not firm to appear that the staple is fixed easily, have the risk that drops easily.
