Abstract

The invention provides a preparation tool for a single-ankle joint replacement bone. The preparation tool comprises a position-limiting depth-limiting adjustable bidirectional reciprocating saw, a dual-fin keel wing preparing machine and an auxiliary infiltrating plate, wherein the structures are sequentially applied, preparation of far end of a shin bone and the bone surface of one end close to the bone can be accurately performed, and comprises osteotomy and preparation of keel, and correct transplanting of a single-ankle joint prosthesis is facilitated. The preparation tool disclosed by theinvention is succinct in operation steps, convenient to use, and accurate in bone bed preparation, and can complete the bone bed preparation within a short time.

Description

technical field [0001] The invention belongs to the technical field of bone surface preparation of the distal end of the tibia and the proximal end of the talus in a single ankle joint replacement operation, in particular to a bone preparation tool for single ankle joint replacement and a method for using the same. Background technique [0002] At present, ankle arthrodesis and artificial total ankle arthroplasty are the mainstream operations for the treatment of end-stage ankle joint diseases, such as traumatic arthritis, osteoarthritis, rheumatoid arthritis and other diseases. The joint function is poor, so total ankle arthroplasty has become a popular treatment method, and its application is gradually increasing. The artificial ankle joints currently used clinically are total ankle joint replacements, that is, the articular surfaces of the distal tibia and the proximal talus are all replaced, but many patients suffer from ankle joint degeneration, cartilage defect or inju...
