Bending tool for cartilage cone under microscope in ankle joint operation of sports medicine

Abstract

The invention discloses a bending tool for a cartilage cone under a microscope in an ankle joint operation of sports medicine. The bending tool comprises a limiting main body, a positioning main body,a limiting pin used for being inserted into the thick section of a cartilage cone to position the cartilage cone, a first contour assembly, a second contour assembly and a bending operation assembly,wherein the bending operation assembly is rotationally connected with the first contour assembly and the second contour assembly to conduct secondary bending on the thin section of the cartilage cone. The positioning main body is mounted to the limiting main body; the first contour assembly and the second contour assembly are detachably installed on the positioning main body; the limiting main body is provided with a first fixing groove allowing the thick section of the cartilage cone to be embedded therein and a pin limiting groove allowing the limiting pin to be embedded therein so as to position the limiting pin; and the bending operation assembly comprises a long rotating plate, a short rotating plate, a rolling wheel and a rotating shaft pin serving as a rotating shaft of the bendingoperation assembly. The bending tool has the beneficial effects that the cartilage cone with a variable cross section is bent twice through one-time clamping, the cost is low, and the machining precision is high.

Description

technical field [0001] The invention relates to a bending tool for cartilage cones under the microscope in ankle joint surgery in sports medicine. Background technique [0002] The bending process of the cartilage cone is mainly based on the bending machine and the bending die. The operation of the bending machine is cumbersome, the structure is complicated, and the cost is high. Generally, bending molds have higher requirements for bending products. For example, the outer diameter of the product is required to be uniform. For products with variable cross-section and double bending requirements, 2 sets of molds are required for bending. The cost of the mold is high and the secondary clamping will also be difficult. Affect the processing accuracy of the product. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a bending tool for the endoscopic cartilage cone in ankle joint surgery in sports medicine. Th...
