技术领域technical field
本发明涉及骨科内固定医疗器具，尤其涉及一种可调节持骨复位钳。The invention relates to an orthopedic internal fixation medical appliance, in particular to an adjustable bone-holding reduction forceps.
技术背景technical background
骨折手术中复位及临时固定是极其关键的一步，通常在这一步耗费的时间最长，尤其对于粉碎性骨折也是最难处理的一步，若能尽快实现理想的复位，手术时间将大大缩短，手术效果也将更为满意。Reduction and temporary fixation are extremely critical steps in fracture surgery. Usually, this step takes the longest time, especially for comminuted fractures. It is also the most difficult step to deal with. If the ideal reduction can be achieved as soon as possible, the operation time will be greatly shortened. The effect will also be more satisfactory.
目前，现有的骨折复位钳功能单一，复位效果不甚理想，最关键的是复位后不能同时插板固定，而能实现复位的同时即可进行固定的复位钳尚无实际应用产品，申请公布号为CN 105011992 A的中国发明专利公开了一种“无遮挡骨折复位钳”，该专利比较合理的实现了在骨折复位同时的固定，但该专利仅适用于简单骨折，且钢板上螺钉时容易受到阻挡，仍存在一定缺陷。At present, the existing fracture reduction forceps have a single function, and the reduction effect is not ideal. The most important thing is that the plate cannot be inserted and fixed at the same time after reduction, and there is no practical application product for the reduction forceps that can be fixed at the same time as the reduction. The Chinese invention patent No. CN 105011992 A discloses a "unshielded fracture reduction forceps". This patent reasonably realizes the fixation while the fracture is reduced, but this patent is only applicable to simple fractures, and it is easy to install screws on the steel plate. Be hindered, still have certain defect.
发明内容Contents of the invention
为了克服现有骨折复位钳复位效率低、不能实现复位后即时固定的设计缺陷，本发明提供了一种“可调节持骨复位钳”，其钳嘴可固定及更换不同型号的挡片，且挡片可根据需要调节前后位置，通过上下复位挡片的相互挤压来实现骨折复位并临时固定，同时留有足够空间可实现钢板的固定，复位后可将钳体左右折弯，不影响操作。In order to overcome the design defects of low reduction efficiency of existing fracture reduction forceps and the inability to achieve immediate fixation after reduction, the present invention provides an "adjustable bone-holding reduction forceps", the jaws of which can be fixed and replace different types of stoppers, and The front and rear positions of the stopper can be adjusted according to the needs. The fracture can be reset and temporarily fixed by pressing the upper and lower return stoppers. At the same time, there is enough space to realize the fixation of the steel plate. After the reset, the clamp body can be bent left and right without affecting the operation. .
为了解决上述技术问题，本发明采用的技术方案是：一种可调节持骨复位钳，包括上、下钳体，上、下钳体通过销钉铆接，钳体通过铰链关节与钳口前部相连，钳口前部与钳嘴连为一体，钳嘴扁平，钳嘴上有钳嘴螺孔，钳嘴则通过螺钉与挡片连接，挡片中部有两条纵行凹槽与钳嘴螺孔位置对应，挡片与钳嘴之间有一垫片。In order to solve the above technical problems, the technical solution adopted in the present invention is: an adjustable bone-holding reduction forceps, including upper and lower forceps bodies, the upper and lower forceps bodies are riveted by pins, and the forceps bodies are connected to the front of the jaws through hinge joints , the front part of the jaw is connected with the pliers mouth, the pliers mouth is flat, there are pliers mouth screw holes, the pliers mouth is connected with the block by screws, there are two longitudinal grooves in the middle of the block and the pliers mouth screw holes Corresponding positions, there is a spacer between the blocking plate and the pliers mouth.
所述的上、下钳体其后段内侧各有一咬合齿条，二者靠拢后可相互咬合。The inner sides of the rear sections of the upper and lower pliers bodies each have an engaging rack, which can be engaged with each other after they get close.
所述的钳嘴为一长方体，其四角位置各有一钳嘴螺孔，钳嘴螺孔具有内丝。The pliers mouth is a cuboid, and each of its four corners has a pliers mouth screw hole, and the pliers mouth screw hole has inner wires.
所述的挡片设计有不同大小及弧度，每一挡片均有一与之配套的垫片。The baffles are designed with different sizes and radians, and each baffle has a matching gasket.
所述的垫片具有共同特征：其大小与钳嘴相同，垫片背面为平面，腹面具有弧度，该弧度与挡片背面弧度一致，垫片四角也各有一垫片螺孔，垫片螺孔位置与钳嘴螺孔位置相同，垫片螺孔不具有内丝。The gaskets have common features: the size is the same as that of the pliers mouth, the back of the gasket is flat, and the ventral surface has a radian, which is consistent with the radian of the back of the retaining piece. The position is the same as that of the jaw screw hole, and the spacer screw hole does not have an inner wire.
所述的挡片其腹面具有既定数量的锥型凸起，挡片中部的两条纵行滑槽其宽度与钳嘴横向位置的钳嘴螺孔等距。The ventral surface of the baffle has a predetermined number of conical protrusions, and the width of the two longitudinal chutes in the middle of the baffle is equidistant from the screw holes in the lateral position of the pliers mouth.
与现有技术相比，本发明的有益效果是：首先，采用复位挡片可较传统复位钳大大增加与骨的接触面积，有利于快速复位；其次，可根据不同粗细的骨骼选用不同型号的挡片，具有更好的适配性；再者，挡片的位置可调节，根据拟选用的钢板宽度可确定挡片可调节的最大区域，这样可适应不同型号的钢板；另外，复位钳可逐步锁紧，有利于复位过程中的不断调整；最后，复位完成后可将上下钳体向侧方折弯，不影响内固定操作的进行。Compared with the prior art, the beneficial effects of the present invention are as follows: firstly, the use of the reset block can greatly increase the contact area with the bone compared with the traditional reset forceps, which is conducive to rapid reset; secondly, different types of clamps can be selected according to different thicknesses of bones. The stopper has better adaptability; moreover, the position of the stopper can be adjusted, and the maximum adjustable area of the stopper can be determined according to the width of the steel plate to be selected, so that it can adapt to different types of steel plates; in addition, the reset pliers can be Gradual locking is conducive to continuous adjustment during the reset process; finally, after the reset is completed, the upper and lower clamp bodies can be bent sideways without affecting the internal fixation operation.
