Thighbone osteotomy device and thighbone osteotomy guide plate assembly

Abstract

The invention relates to the technical field of medical instruments, and provides a thighbone osteotomy device and a thighbone osteotomy guide plate assembly. The thighbone osteotomy device comprises an osteotomy device body, an osteotomy groove is formed in the osteotomy device body, an osteotomy tool can be inserted into the osteotomy groove to conduct osteotomy on the thighbone, a plurality of positioning holes which are sequentially formed at intervals are formed in the osteotomy device body, and the positioning holes are suitable for being matched with threaded nails to adjust the osteotomy amount of the thighbone. When the osteotomy amount needs to be adjusted, the threaded nails penetrate through the corresponding positioning holes in a matched mode, and the osteotomy amount can be adjusted according to needs. By the adoption of the thighbone osteotomy device, the multiple positioning holes are formed in the different positions of the osteotomy device body, the osteotomy amount can be correspondingly adjusted, and therefore the osteotomy effect is improved. The invention further provides a thighbone osteotomy guide plate assembly. A thighbone osteotomy guide plate and the thighbone osteotomy device are combined, and the thighbone osteotomy guide plate and the thighbone osteotomy device are matched and positioned through threaded nails.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a femoral osteotomy device and a femoral osteotomy guide plate assembly. Background technique [0002] Knee replacement osteotomy guide is a surgical auxiliary tool. Using the guide, it does not require pulp opening, reduces surgical trauma, simplifies the tools used in surgery, improves surgical efficiency, and shortens the learning curve for doctors to ensure surgical efficiency. Moreover, the guide plate is customized according to the bone quality of the patient, which greatly improves the accuracy of the operation. [0003] At present, most of the guide plates are designed as a whole, and are 3D printed with nylon material, resin material or polylactic acid material as a whole. The materials for producing guide plates using 3D printing technology need to meet multiple requirements such as biological and mechanical properties and be suitable for 3D printing processes,...

AI Technical Summary

Problems solved by technology

[0007] The invention provides a femoral osteotomy device and a femoral osteotomy guide plate assembly, which is used to solve the problem that the osteotomy guide plate in the related art cannot be added or subtracted, the practicability is low, the matching position of the guide plate is prone to deviation during the installation process, and there are also problems during the installation process. A certain installation error will seriously affect the effect of osteotomy. By setting multiple positioning holes at different positions of the osteotomy, the amount of osteotomy can be adjusted accordingly, which can assist the operator to perform precise osteotomy and improve the effect of osteotomy.
