A department of orthopedics reduction forceps adjustable locking function, including two pliers handle and a rotating shaft, the clamp handle is connected with the middle shaft to rotate through, the clamp handle are fixedly connected with the lower end of the hand ring, the ring on the middle finger is provided with a through hole, the through hole on the side of the hand ring groove is arranged on the open set mouth down, the groove top is fixedly connected with a reset spring, a reset spring is fixed on the lower end is connected with a vertical rod. The beneficial effect of the utility model is in use, the finger rest to clamp the finger in the action of a return spring pressure, so it can adapt to different thickness of the fingers, can also increase the friction between the finger and the finger support in the process of using, the clamp is not easy to slip, improve the safety of the operation; when the clamping the bone plate is clamped, in order to make bones without slipping, using connection limit hole and screw spacing groove locking screw, the clamp handle not to rotate around the rotating shaft, to ensure the stability of bone holding.

技术介绍
骨科是各大医院最常见的科室之一,主要研究骨骼肌肉系统的解剖、生理与病理,运用药物、手术及物理方法保持和发展这一系统的正常形态与功能。随着时代和社会的变更,骨科伤病谱有了明显的变化,例如,骨关节结核、骨髓炎、小儿麻痹症等疾病明显减少,交通事故引起的创伤明显增多。常见骨科病:髌骨骨折、尺神经损伤、先天性髋内翻、断指再植、趾间神经痛、距骨后外结节骨折、拇指再造、先天性胫骨缺如、僵鉧、感染性肋软骨炎、颞下颌关节强直、风湿热、眼眶击出性骨折、腘肌肌腱炎、跖趾关节痛、胫后神经痛、跟腱前囊炎、纤维肌痛症、滑囊炎、感染性关节炎、足舟状骨骨软骨病、姿态性腰腿痛、赖特综合征、灼性神经痛、纤维肌痛综合症等。骨折后一般需采用复位钳将断骨进行复位,并通过钢板、螺钉等进行固定。在现有技术中,医护人员利用复位钳将断骨夹住,然后移动进行复位,但是却没有锁紧功能,容易造成断骨的掉落,从而影响手术的操作;同时,现有复位钳的手指环大小相同,而不同医护人员手指的粗细不一,因此其适用范围较小。技 ...
