技术领域Technical Field
本实用新型属于医疗器械技术领域，具体涉及一种钢板固定复位钳。The utility model belongs to the technical field of medical instruments, and in particular relates to a steel plate fixing and reduction forceps.
背景技术Background Art
持骨钳是骨科手术中用于夹持骨骼的钳子，起到对骨头固定、复位的作用，通常由钳体以及连接轴组成，整体一般采用不锈钢材质制成。Bone forceps are pliers used to clamp bones in orthopedic surgery. They play the role of fixing and repositioning bones. They are usually composed of a pliers body and a connecting shaft, and the whole body is generally made of stainless steel.
在骨折复位手术过程中，对于需要植入钢板对断裂的骨头之间固定时，需要先将骨头复位对齐，再植入钢板，最后使用钢钉将钢板固定在骨头上，这一过程中，若是钢板没有进行初步固定，在安装钢钉之前，钢板极易发生移位，导致钢板的安装位置不准确，因此，在安装钢钉之前，需要先对钢板进行初步辅助固定，而现有的持骨钳只能用于夹持骨骼，用于拉动骨骼复位，无法用于植入钢板的辅助固定。During the fracture reduction surgery, when a steel plate needs to be implanted to fix the broken bones, the bones need to be repositioned and aligned first, then the steel plate is implanted, and finally the steel plate is fixed to the bones with steel nails. During this process, if the steel plate is not initially fixed, it is very easy to shift before the steel nails are installed, resulting in inaccurate installation position of the steel plate. Therefore, before installing the steel nails, the steel plate needs to be initially fixed with auxiliary fixation. The existing bone clamp can only be used to clamp bones and pull bones to reduce their position, and cannot be used for auxiliary fixation of implanted steel plates.

本实用新型的使用原理如下：The operating principle of the utility model is as follows:
使用持骨钳将骨骼夹持住，并拉动骨骼复位，将植入钢板置于骨折位置，驱动纵向调节杆7绕着横向调节杆4的中心线转动，使纵向调节杆7朝向植入钢板，再旋紧紧固螺栓5，对横向调节杆4进行固定；按下按钮10，使压块8与纵向调节杆7分离，此时能够对纵向调节杆7沿着导向套6进行快速调节，当纵向调节杆7下端的压紧块13靠近钢板时，松开按钮10，在弹性件9的作用下，压块8会压紧在纵向调节杆7上，使压块8上的内螺纹重新与纵向调节杆7上的外螺纹螺接，此时可通过转动纵向调节杆7来调整纵向调节杆7的纵向位置，使压紧块13上的插接部15插入植入钢板上的孔内，并使连接部14上的台阶面16轻压在植入钢板上，此时若是需要调整植入钢板的沿着骨骼的横向位置，可松开紧固螺栓5，推动或拉动横向调节杆4，通过观察横向调节杆4上的刻度线来控制植入钢板的移动距离，调整完成后旋紧紧固螺栓5，在转动纵向调节杆7使压紧块13压紧在植入钢板上，对植入钢板实现辅助固定，接着就能使用钢钉将植入钢板固定在骨骼上即可。若是不需要使用本实用新型对植入钢板的辅助固定功能，可使导向套6和横向调节杆4相对转动，使横向调节杆4与导向套6分离，就能将横向调节杆4与导向套6等部件从持骨钳上拆下，此时本实用新型可作为普通的持骨钳使用，十分方便。Use bone holding forceps to clamp the bone and pull the bone to reset, place the implanted steel plate in the fracture position, drive the longitudinal adjustment rod 7 to rotate around the center line of the transverse adjustment rod 4, so that the longitudinal adjustment rod 7 faces the implanted steel plate, and then tighten the fastening bolt 5 to fix the transverse adjustment rod 4; press the button 10 to separate the pressure block 8 from the longitudinal adjustment rod 7. At this time, the longitudinal adjustment rod 7 can be quickly adjusted along the guide sleeve 6. When the pressure block 13 at the lower end of the longitudinal adjustment rod 7 approaches the steel plate, release the button 10. Under the action of the elastic member 9, the pressure block 8 will be pressed on the longitudinal adjustment rod 7, so that the internal thread on the pressure block 8 is screwed with the external thread on the longitudinal adjustment rod 7 again. At this time, The longitudinal position of the longitudinal adjustment rod 7 can be adjusted by rotating the longitudinal adjustment rod 7, so that the plug-in portion 15 on the clamping block 13 is inserted into the hole on the implant steel plate, and the step surface 16 on the connecting portion 14 is lightly pressed on the implant steel plate. At this time, if it is necessary to adjust the lateral position of the implant steel plate along the bone, the fastening bolt 5 can be loosened, and the lateral adjustment rod 4 can be pushed or pulled. The moving distance of the implant steel plate can be controlled by observing the scale line on the lateral adjustment rod 4. After the adjustment is completed, the fastening bolt 5 is tightened, and the longitudinal adjustment rod 7 is rotated to make the clamping block 13 clamped on the implant steel plate to achieve auxiliary fixation of the implant steel plate. Then, the implant steel plate can be fixed on the bone with steel nails. If the auxiliary fixation function of the implant steel plate of the utility model is not needed, the guide sleeve 6 and the lateral adjustment rod 4 can be relatively rotated to separate the lateral adjustment rod 4 from the guide sleeve 6, and the lateral adjustment rod 4 and the guide sleeve 6 and other components can be removed from the bone holding forceps. At this time, the utility model can be used as an ordinary bone holding forceps, which is very convenient.
