The utility model discloses a three in one pull hook for hip joint replacement, which comprises a handle, a pull hook body and a pull hook. The pull hook body is arranged at the front end of the handle. The pull hook includes a main hook arranged at the front end of the pull hook body, a lateral auxiliary hook arranged at the outer side of the pull hook body, a medial auxiliary hook arranged at the inner side of the pull hook body. The medial auxiliary hook and the lateral auxiliary hook are relatively arranged, Hook from the inside and outside of the hook to the upper side of the hook body. The utility model relates to a three in one pull hook for hip joint replacement. Through the innovative structural design, one pull hook has the function of the previous three pull hooks, and the elastic parts of the internal and external soft tissues are mutually offset, and the pull hook does not slide out, so as to fully expose the proximal end of the femur, so as to achieve the effect that only one hand is required to grasp the handle of the three in one pull hook during the operation, which has the saving effect Human time, no need to insert the hook repeatedly, and improve the efficiency of the operation.
【技术实现步骤摘要】
一种髋关节置换用股骨三合一拉钩
本技术涉及医疗器械
,具体地,涉及一种髋关节置换用股骨三合一拉钩。
技术介绍
人工髋关节置换术是用股骨头假体和髋臼假体置换被疾病或损伤所破坏的关节面的手术。髋关节与股骨头的连接处为髋臼,置换前需要把髋臼处的关节囊清除。目前,在人工髋关节置换术中基本手术器械都是创伤骨科器械,缺乏髋关节置换专用器械,是造成人工髋关节置换暴露困难、手术时间相对较长的主要原因。目前在人工全髋关节置换术中处理股骨时,一般使用2-3把髋臼拉钩,其中一把髋臼拉钩用于撬起股骨近端(股骨颈截骨残端),使其离开髋臼(即组织深处),另一把髋臼拉钩用于牵开小粗隆侧组织(包括局部筋膜、肌肉等)。有时还需一把髋臼拉钩拉开臀中肌,如此才能充分暴露截骨后的股骨近端。这样暴露股骨近端需要三把拉钩和三只手,耗费较多人力。
技术实现思路
本技术的目的在于提供一种髋关节置换用股骨三合一拉钩,以解决上述
技术介绍
中提出的问题。为实现上述目的,本技术提供如下技术方案:一种髋关节置换用股骨三合一拉钩,包括手柄、拉钩本体、拉钩,所述拉钩本体设于所述手柄前端,所述拉钩包括设于所述拉钩本体前端的主钩、设于拉钩本体外侧的外侧副钩、设于拉钩本体内侧的内侧副钩,所述内侧副钩、外侧副钩相对设置,分别从拉钩本体内、外两侧向拉钩本体上侧上钩。这里,所述主钩可以撬起股骨近端(股骨颈截骨残端),内侧副钩可以阻挡内侧(小粗隆一侧)软组织(臀大肌及其筋膜),外侧副钩可以阻挡外侧(大粗隆一侧)软组织(臀大肌、臀中肌及筋膜)。优 ...
