Description

Technical Field

[0001] The utility model relates to the technical field of medical rehabilitation equipment, in particular to a rehabilitation device for reconstruction of foot and ankle joint ligaments. Background Art

[0002] The ankle ligaments mainly include the ligaments between the distal end of the fibula and the distal end of the tibia, mainly the anterior tibiofibular ligament and the posterior tibiofibular ligament. On the inner side of the ankle joint are the tibial ligaments, tibial root ligaments, and tibiotalar ligaments between the tibia, navicular bone, talus, and calcaneus, which together form a roughly triangular structure, also known as the triangular ligament. The ruptured ligament can be rehabilitated through rehabilitation training and slowly restored to its pre-injury state.

[0003] The existing patent CN218529673U, a foot and ankle joint ligament reconstruction rehabilitation device, is provided with a sliding column, a triangular plate, and a second stopper, so that when we use it, we can control the mounting seat to move to the end closest to ourselves. At this time, the sliding column is squeezed and moved upward in contact with the triangular plate, so that its upper end lifts the second stopper to drive the rotating shaft to rotate, and drives the two foot pedals to rotate to a horizontal state, which is convenient for patients to put their feet in without manually straightening the foot pedals, further facilitating the patient's use. However, the seat in this patent adopts a fixed height and cannot be adjusted. This will cause patients who are too tall to be unable to stretch their legs well, which is not conducive to the patient's rehabilitation. Utility Model Content

[0019] 2. The foot and ankle joint ligament reconstruction rehabilitation device is implemented by inserting the telescopic belt into the groove provided on the first strap. At this time, the plastic buckle provided on the telescopic belt hits the inner wall of the groove and contracts under the force. At the same time, the plastic buckle applies pressure to the spring fixedly connected to the front surface. The spring contracts under the force. At the same time, the plastic buckle slides forward and contracts into the spring groove. The telescopic belt is continuously inserted into the groove. At this time, the plastic buckle passes through the clamping hole. At this time, the plastic buckle is no longer subjected to the pressure applied by the inner wall of the first strap. At the same time, the spring is no longer subjected to the force. At this time, the spring expands and applies a backward thrust to the plastic buckle fixedly connected to the rear surface, so that it moves backward and is clamped into the clamping hole for fixation. The foot and ankle joint ligament reconstruction rehabilitation device can be used to fix patients with different foot sizes, and when it is adjustable, the patient can get a comfortable fixation when fixing the foot, which is more convenient and practical.
