Problems solved by technology

[0005] But this operation still has following deficiency at present: the one, the metal screw that internal fixation is used, will carry out secondary operation after the operation to be taken out, thus increased the misery of patient; There are various forms of fixation, and patients need to stay in bed for 3-4 months after operation; after using external fixation brackets and bone circular needles, the patient will have inconvenience in dressing and wearing shoes, and cannot get out of bed, which will bring new life to life. so much inconvenience

Embodiment Construction

[0016] Such as figure 1 As shown, the ankle joint fusion device of the present invention includes a hollow pile frame 1 and a shoulder frame 2 plugged with the pile frame 1 . The pile frame 1 is in the shape of a quadrangular prism, and square bone graft contact holes are respectively opened on its top and bottom surfaces; strip-shaped bone graft contact holes 3 are opened on each side surface of the pile frame 1, and the bone graft contact holes 3 are formed on each side surface of the pile frame 1. A circular nourishing hole 4 is respectively opened on both sides of the hole 3 . The shoulder frame 2 is a bridge-shaped structure, the middle part is flat and has an insertion opening, which is used to insert the pile frame 1; the two ends of the shoulder frame are two wings, one large and one small, which are bent downwards, corresponding to the physiology of the medial malleolus and lateral malleolus. Bend, that is, the small wing end is placed in the ankle space on the media...

Abstract

The invention relates to an absorbable ankle fusion device, which comprises a prismatic hollow pile frame made from polymer materials capable of being absorbed by the human body, and a shoulder frame matched with the pile frame and made from polymer materials capable of being absorbed by the human body; wherein the lateral surface of the pile frame is provided with a bone graft contact hole and anutrient foramen; a penetrating hole spliced with the pile frame is arranged in the middle of the shoulder frame, the two ends of the shoulder frame are respectively provided with two wings which bend downwards and are respectively arranged in gaps between a malleolus medialis and an ankle bone and between a lateral malleolus and the ankle bone, and two wings of the shoulder frame are respectively provided with bone graft contact holes and nutrient foramens. The absorbable ankle fusion device has the advantages of simple structure, convenience for operation and use safety, can realize the interior fixation between a tibia and the ankle bone and enable a grafted autologous bone to fully contact a surface of a new bone wound, which is beneficial to the formation of bone fusion.

Description

technical field [0001] The invention relates to an ankle joint treatment device, in particular to an absorbable ankle joint fusion device. Background technique [0002] Cartilage tissue wear is prone to occur after ankle trauma, resulting in the uneven cartilage surface of the ankle joint, which eventually leads to traumatic arthritis of the ankle joint. The main symptoms of traumatic arthritis are pain and limited mobility. [0003] Currently, there are two main treatment methods for ankle traumatic arthritis: one is ankle arthroplasty and the other is ankle arthrodesis. In view of the poor long-term treatment effect of the former, relatively high surgical costs, and many complications, most patients prefer to choose ankle arthrodesis for treatment. [0004] Ankle fusion is to implant autogenous bone between the tibia and fibula of the patient's calf and the talus of the foot (that is, at the ankle joint position), so that the two can be integrated into one body, so that t...
