胫骨近端骨板proximal tibial plate

技术领域technical field

本实用新型是关于一种骨板，特别是一种适用于胫骨近端后侧处的胫骨近端骨板。The utility model relates to a bone plate, in particular to a proximal tibial bone plate suitable for the rear side of the proximal tibia.

背景技术Background technique

目前用于处理近关节处骨折的通用型T形骨板（T-plate），多为平板形态的T形结构；使用时，由医疗人员按照患者骨骼的外表形状，通过弯折工具扳折该现有的T形骨板，使该T形骨板各部位，特别是该T形骨板的头部以及头部与身部的连接处，形成贴近患者骨骼外形的曲面，再搭配数个骨钉将该T形骨板锁合固定于患部。At present, the general-purpose T-shaped bone plate (T-plate) used to treat fractures near the joint is mostly a T-shaped structure in the shape of a flat plate; when in use, the medical staff uses a bending tool to bend the bone plate according to the shape of the patient's bone. In the existing T-shaped bone plate, each part of the T-shaped bone plate, especially the head of the T-shaped bone plate and the joint between the head and the body, forms a curved surface close to the shape of the patient's bone, and then several bone plates are matched. The nails lock and fix the T-shaped bone plate to the affected part.

然而，于手术时才扳折该T形骨板，将大幅地增加手术时间，无形中造成了大量的医疗资源浪费。此外，该现有的T形骨板具有十分优良的结构强度，使得扳折改变该T形骨板的弧度相当不容易，因此扳折该T形骨板时，多会从结构强度较弱处─该T形骨板上供骨钉穿设的各穿孔进行扳折；但是如此，却易造成各穿孔的变形，导致骨钉与该T形骨板之间锁固的密合度降低，使得术后容易产生该T形骨板松脱或摇晃的状况。However, only pulling the T-shaped bone plate during the operation will greatly increase the operation time and virtually cause a lot of waste of medical resources. In addition, the existing T-shaped bone plate has very good structural strength, so it is not easy to change the curvature of the T-shaped bone plate. ─Break the perforations on the T-shaped bone plate for the bone nails to pass through; however, it is easy to cause the deformation of each perforation, resulting in a decrease in the tightness of the locking between the bone nails and the T-shaped bone plate, making the operation Afterwards, the T-shaped bone plate is easy to loosen or shake.

另，胫骨（tibia）近端处是经常使用到骨板的部位，凡是退化性关节炎所适用的胫骨高位切骨术，或是一般骨折复位的定位等情况，都会将骨板施用于胫骨近端处。因此，有必要针对胫骨近端处，提供一种可贴合于胫骨近端后侧处的骨板。In addition, the proximal end of the tibia is the place where the bone plate is often used. For high tibial osteotomy for degenerative arthritis, or general fracture reduction positioning, the bone plate will be applied to the proximal tibia. at the end. Therefore, it is necessary to provide a bone plate that can fit on the posterior side of the proximal tibia for the proximal tibia.
