Description
本創作係關於一種股骨固定裝置，特別指組裝式之股骨固定裝置。This creation is directed to a femoral fixation device, particularly an assembled femoral fixation device.
人體各部位的骨骼形狀不盡相同且構造複雜，若發生骨折等傷害，在醫學上提供治療與復健的方式通常需依據受傷部位的骨骼結構而給予適當的治療，當骨折的部位靠近關節處時，較不適合使用石膏固定，則通常會採取骨板以及骨釘做為治療骨折的固定物。The bone shape of each part of the human body is different and the structure is complex. If a fracture or the like occurs, the medical treatment and rehabilitation method usually requires appropriate treatment according to the bone structure of the injured part. When the fracture is near the joint When it is less suitable for plaster fixation, bone plates and bone nails are usually used as fixes for the treatment of fractures.
以股骨骨折來說，當骨折處靠近股骨頂端之股骨頭時，治療方式是採用一種一體成型之骨板將股骨固定，該骨板係呈一長形板體，該板體之形狀、以及表面弧度係需對應患者股骨之形狀、長度以及表面弧度進行設計，該板體具有複數穿刺塊與複數骨釘孔，該等穿刺塊係突伸成形於該板體之一內壁，該等骨釘孔係穿設於該板體；治療時係透過該等穿刺塊將該骨板固定於股骨頂端並將板體貼靠於股骨，接著再將骨釘穿過該等骨釘孔釘入股骨中以固定股骨而達到治療骨折之效果。In the case of femoral fractures, when the fracture is near the femoral head at the tip of the femur, the treatment is to fix the femur with an integrally formed bone plate, which is an elongated plate, the shape and surface of the plate. The curvature system is designed according to the shape, the length and the surface curvature of the patient's femur. The plate body has a plurality of piercing blocks and a plurality of bone nail holes, and the piercing blocks are protruded and formed on one inner wall of the plate body, and the bone nails are formed. The hole is threaded through the plate body; the bone plate is fixed to the top of the femur through the piercing block and the plate body is abutted against the femur, and then the bone nail is inserted into the femur through the bone nail hole. Fix the femur to achieve the effect of treating fractures.
然而，雖然通常不同患者間股骨中段的差異不大，但是股骨頂端的形狀以及彎曲度的差異極大，因此對於不同的患者就必須要開設不同模板之骨板並重新製做整個骨板，造成製造成本上的增加，而成本的增加也將轉嫁到患者的身上，增加患者醫療費用方面的負擔。However, although the difference in the mid-femoral section between different patients is usually small, the shape and curvature of the femoral tip are extremely different. Therefore, it is necessary for different patients to open bone plates of different templates and re-build the whole bone plate, resulting in manufacturing. The increase in cost, and the increase in cost will also be passed on to the patient, increasing the burden on the patient's medical expenses.
為了改善前述之缺點，本創作提供一種股骨固定裝置，其包含：一上骨板、一下骨板與一固定組件，該上骨板係具有一上結合部與複數穿刺塊，該上結合部係設置於該上骨板底端，該等穿刺塊係突伸成型於該上骨板之一內面；該下骨板具有一下結合部，該下結合部係設置於該下骨板頂端；該固定組件包含一固定單元，該固定單元係分別與該上骨板之上結合部以及該下骨板之下結合部可分離地相連接。In order to improve the aforementioned disadvantages, the present invention provides a femoral fixation device comprising: an upper bone plate, a lower bone plate and a fixing component, the upper bone plate having an upper joint portion and a plurality of piercing blocks, the upper joint portion The bottom of the upper bone plate is formed on the inner surface of the upper bone plate; the lower bone plate has a lower joint portion, and the lower joint portion is disposed at the top end of the lower bone plate; The fixing component comprises a fixing unit which is detachably connected to the upper upper plate joint portion and the lower bone plate lower joint portion, respectively.
