Description

Technical Field

[0001] The invention relates to the technical field of medical rehabilitation and physical therapy, and in particular to a physical therapy device for post-operative ankle ligament repair. Background Art

[0002] The ankle ligaments can be divided into three groups according to their anatomical position: the lateral collateral ligament, the medial collateral ligament (deltoid ligament) and the syndesmotic ligament; the lateral collateral ligament complex includes: the anterior talofibular ligament, the calcaneofibular ligament, and the posterior talofibular ligament; the deltoid ligament is a complex ligament with a fan-shaped structure, consisting of a superficial layer and a deep layer. The deltoid ligament and other ankle structures work together to maintain the stability of the ankle joint; the distal syndesmotic ligament consists of four ligaments, including: the interosseous ligament, the anterior tibiofibular ligament, the posterior tibiofibular ligament, and the inferior transverse ligament. Injury to the lateral ligament of the ankle joint is very common, among which inversion sprain is the most common, accounting for 85%; among sports injuries of basketball players, 53% are injuries to the lateral collateral ligament of the ankle joint; among sports injuries of football players, 21% are injuries to the lateral collateral ligament of the ankle joint. Injury to the deltoid ligament can be caused by direct or indirect violence, and most are caused by direct violence, that is, crushing, collision, and hitting. The mechanism of syndesmotic ligament injury is usually external rotation and excessive dorsiflexion of the ankle joint. Sports that can cause syndesmotic injury include sports (such as football), low-energy trauma, etc.; external rotation injuries usually occur in the pronation or supination position of the ankle joint. Syndesmotic ligament injury can be a single injury or combined with fracture.

[0003] When the ankle ligament injury is mild, braking should be performed in time to achieve the purpose of self-healing through the body's self-repair function. When the ligament injury is serious, surgery should be performed in time to reconstruct the ligament to restore the ankle joint. After the ankle ligament injury surgery, rehabilitation exercises and physical therapy activities should be performed in time to prevent ankle joint stiffness and ligament adhesion and contracture.

[0004] At present, due to the lack of dedicated postoperative physiotherapy equipment for ankle ligament exercise, most rehabilitation equipment used for postoperative ankle ligament exercise uses ankle pump exercisers, which can perform plantar flexion and dorsiflexion exercises on the patient's ankle joint. This exercise method has a good stretching effect on the Achilles tendon. However, the current ankle pump exercisers have the following defects: 1. The patient needs to use it in a supine position, and it is impossible to apply a certain weight to the patient in a sitting position to further improve the exercise effect of plantar flexion and dorsiflexion; 2. It is impossible to perform internal and external rotation of the ankle joint under the condition of applying weight to exercise the lateral ligament; 3. It is impossible to massage the corresponding acupoints on the sole of the foot to improve the blood circulation of the patient's sole to improve the comfort and satisfaction of the exercise; 4. It is impossible to massage and relieve the Achilles tendon ligament to prevent the contracture of the Achilles tendon ligament. Summary of the invention

[0024] A specific application of the device is: when using it, the patient puts his feet into the physiotherapy basin, the patient's forefoot is placed on the forefoot support plate 6, the heel is placed on the heel support plate 5, and the heel is against the heel embrace plate of the Achilles tendon ligament massage mechanism 13. A certain stepping force is applied to the forefoot support plate and the heel support plate to apply weight to the ankle joint. Under this weight, the switch and operation time of plantar flexion, dorsiflexion, internal rotation, external rotation, arch massage and Achilles tendon ligament massage can be controlled by operating the button 4. The operation principles of various actions are as follows: (1) Plantar flexion movement: The controller 11 controls the heel lift electric push rod 15 to rise through the relay module. At this time, the heel lift electric push rod 15 will push the heel support plate 5 to move upward through the anti-roll arc support plate 161, and the heel support plate 5 will push the heel upward to achieve plantar flexion movement; (2) Dorsiflexion: The controller 11 controls the heel lift electric push rod 15 to descend to the initial height through the relay module, and then controls the forefoot lift electric push rod 16 to rise through the relay module. The forefoot lift electric push rod 16 pushes the forefoot support plate 6 upward through the anti-roll arc support plate 161, and the forefoot support plate 6 pushes the forefoot upward to achieve dorsiflexion; (3) Internal rotation and external rotation movement: The controller 11 controls the internal and external rotation driving motor 101 to rotate forward or reverse through the relay module. At this time, the gear shaft 102 will rotate forward or reverse accordingly, and the forefoot support plate 6 meshing with the gear shaft 102 will rotate accordingly. The forefoot support plate 6 drives the heel support plate to rotate through the connecting rod mechanism 7, and the heel support plate rotates around the internal and external rotation support rod 12 as the axis, thereby exercising the lateral ligament; (4) Foot arch massage: The controller 11 controls the horizontal drive motor 81 to rotate forward or reverse through the relay module, and the lead screw also rotates forward or reverse accordingly. The slider threadedly connected to the lead screw moves left or right along the lead screw under the constraint of the limit plate, and the massage ball head 87 and the column 86 move left or right along with the slider, and the massage ball head 87 performs reciprocating massage on the bottom of the foot arch; (5) Massage of the Achilles tendon ligament: Rotate and adjust the primary extension rod 136 and the secondary extension rod 137 so that the clamping massage ball heads 138 on both sides are gently clamped on the skin on both sides of the Achilles tendon ligament. The controller controls the height adjustment drive motor 134 to rotate forward or reverse through the relay module, and the lead screw also rotates forward or reverse accordingly. The lifting adjustment slider threadedly connected to the lead screw moves upward or downward along the lifting slide slot, so that the clamping massage ball head massages the heel ligament. The above operations can be performed singly or in combination, and each operation is performed under weight-bearing conditions to improve the exercise effect of the ankle ligaments after surgery.
