Description

髓腔锉手柄 Canal file handle

技术领域 FIELD

[0001] 本发明涉及人工关节技术领域,具体而言,涉及一种髓腔锉手柄。 [0001] The present invention relates to artificial joints technical field, particularly, to a canal file handle.

背景技术 Background technique

[0002] 髋关节置换术已经出现很长时间了,其主要是通过手术工具清除关节位置病灶后植入人工髋关节假体的方法,来改善病患的生活品质,消除疼痛。 [0002] Hip replacement surgery has been around for a long time, the main method is to remove the implantation of artificial hip prosthesis after the joint position of lesions by surgical tools, to improve the quality of life of patients and eliminate the pain. 在装入髋关节假体之前, 需要使用专用的髓腔锉将髓腔内的松质骨去掉,为假体安装提供位置。 Before loading hip prosthesis, requires a special file cancellous bone canal in the medullary cavity is removed, to provide the prosthesis mounting position. 由于去除骨质需要外力的敲击,而又不能在术中敲击髓腔锉本体,所以需要髓腔锉打拔器用来将髓腔锉击入或拔出患者髓腔。 Because of the need to remove bone tap external forces, but could not knock canal file body during surgery, so it is necessary to fight canal file puller is used to pull out or hit into the canal filing patient canal.

[0003] 现有技术中,由于要将髓腔锉与髓腔锉打拔器紧紧连接,不能产生晃动,所以通常采用两种方式连接。 [0003] In the prior art, since the canal file you want to play with the canal file puller firmly connected, can rattle, it is usually connected in two ways. 第一种为螺纹连接,安装时将髓腔锉与髓腔锉打拔器通过螺纹连接在一起,但是经过长时间的敲击后,螺纹精度受影响,会造成连接不稳,导致拔出时将髓腔锉留在髓腔内,延长手术时间,影响手术。 A first threaded connection, when installed intramedullary canal file and pulling a file connected together by a screw, but after a long tap, thread accuracy is influenced, may cause unstable connection, resulting in pulled out He will remain in the intramedullary canal file, extend the operation time, affect the operation. 第二种为弹簧夹连接,在打拔器器体的尾部有一可做回转运动的弹簧夹,在使用时将弹簧夹夹紧,前段同时将髓腔锉夹紧,但是使用过程中需要操作者双手施以很大的力量才可将弹簧夹夹紧或松开,虽然连接稳定但操作复杂、费力, 髋关节手术出血量较大,手术时间的延长会对造成损伤。 The second spring clip connector with a spring clip do rotary motion at the end of playing the puller body, to clamp the wire during use, while the anterior clamping canal file, but the process requires the use of an operator hands impose great power before the spring clip clamp or release, although the connection is stable but complex operation, laborious, hip joint surgery large amount of bleeding, prolonged surgery time will cause damage.
