Improved guide plate

Abstract

The invention discloses an improved guide plate for osteotomy. The guide plate comprises a flat plate, two symmetric sides of the flat plate are belt toward the same direction to form a connecting section for connecting with a first metatarsal bone, a notch is formed in the flat plate and comprises a long edge and a short edge, the long edge of the notch is parallel to the length direction of the connecting section, a 45-degree angle is formed between the long edge and the short edge of the notch, a plurality of rectangular holes communicated with the notch are formed in the long edge of the notch of the flat plate, two long edges of each rectangular hole are parallel to the short edge of the notch, the rectangular holes are parallelly formed in an equally spaced manner, and a connecting hole is formed in the connecting section. According to the guide plate, bone cutting distances can be adjusted according to surgery requirements, an expected Z-shaped groove is sawn on a diaphysis of the first metatarsal bone along a z shape by the aid of the z shape formed by the rectangular holes and the notch, so that deviation of the sawn z-shaped groove is avoided, better surgery effect can be achieved by the guide plate, and osteotomy accuracy can be improved.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to an improved guide plate for osteotomy surgery. Background technique [0002] In the existing orthopedic medical treatment methods, the bone deformity can be corrected and treated by osteotomy, the excess bone tissue can be removed, or the bone can be cut to fill a section of prosthesis. The final result is to make the bone length and The shape meets the predetermined requirements. [0003] Many operations involving the foot and ankle require osteotomy, such as valgus osteotomy, which requires soft tissue lysis combined with metatarsal osteotomy and internal displacement and screw fixation to achieve the purpose of orthopedics and fusion. Most bones are based on the doctor’s personal experience. Inaccurate and improper osteotomy often occur. In addition, the foot bones are relatively small, which requires relatively high osteotomy accuracy. Therefore, it is necessary to design a...

AI Technical Summary

Problems solved by technology

[0003] However, many operations involving the ankle require osteotomy, such as valgus valgus osteotomy, which requires soft tissue release combined with metatarsal osteotomy and medial movement and screw fixation to achieve the purpose of orthopedic and fusion. Osteotomy is based on the doctor's personal experience, and the osteotomy is often inaccurate and not in place. In addition, the bones of the foot are relatively small, which requires relatively high accuracy of osteotomy. Therefore, it is necessary to design a targeted guide plate to prevent the doctor from The uncontrollability of freehand operation, and the selectivity of cutting size and angle

At present, there are some guide plates used for the osteotomy of the distal end of the first metatarsal and the diaphysis, but there are some problems with the current guide plates. For example, the existing guide plates do not fully meet the clinical application. Single, unable to adjust the osteotomy distance and cutting angle, etc.
