Description

用于人工膝关节置换手术的腕锤
技术领域
本发明涉及医疗设备技术领域，具体涉及一种用于人工膝关节置换手术的腕锤。
背景技术
人体膝关节是由大腿骨或叫股骨、小腿骨的胫骨和腓骨、髌骨构成的。在股骨和胫骨之间有软骨盘，分别称为内侧半月板和外侧半月板。股骨前下端有槽合适安放髌骨，这些关节的表面覆盖软骨，能吸收震动承受压力。软骨特别是半月板在运动时是人体最易受伤的部分，一旦关节受损，就会造成关节疼痛、功能障碍，人工关节置换能有效的重建关节功能，提高患者的生活质量。
膝关节置换包括单髁置换、膝关节表面置换和铰链式全膝关节置换。对于单纯的内侧或外侧间隔的病变，理论上可以选择单髁置换。铰链式全膝关节可应用于膝关节肿瘤截除术后以及膝关节稳定性丧失的全膝翻修术。根据患者情况，可订做不同长度的假体，产品分为单纯铰链膝关节、股骨铰链膝关节、胫骨铰链膝关节、股胫骨铰链膝关节。
传统观人工膝关节置换手术中要反复多次用锤子向骨内打入钉子，每用一次都需要器械护士递一次钉子和锤子，重复数十次，费时费力。
发明内容
针对现有技术的不足，本发明公开一种用于人工膝关节置换手术的腕锤，能够解决现有人工膝关节置换手术中锤子使用费时费力的问题。
为实现以上目的，本发明通过以下技术方案予以实现：
一种用于人工膝关节置换手术的腕锤，包括锤头、腕带和钉子，所述锤头包括敲击部、贮存部和缓冲部，所述敲击部、贮存部和缓冲部依次固连为一体，所述贮存部具有贮存孔，所述钉子设置在贮存孔中，所述腕带通过铰链连接在贮存部外壁。
优选的，所述敲击部截面为梯形。
优选的，所述贮存孔内壁设有一层橡胶。
优选的，所述缓冲部材质为海绵。
优选的，所述腕带包括锁头、带体和锁孔，所述锁头与带体铰接，所述锁孔设置在带体上。
本发明公开一种用于人工膝关节置换手术的腕锤，本腕锤像手表一样戴在手腕上，省去器械护士的劳动，省时省力，提高手术效率。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明的俯视结构示意图；
图2是本发明中锁头的结构示意图。
图中1、腕带，2、锤头，3、钉子，101、锁头，102、带体，103、锁孔，201、敲击部，202、贮存部，203、橡胶，204、贮存孔，205、缓冲部。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1至图2所示，本发明实施例所述一种用于人工膝关节置换手术的腕锤，包括锤头、腕带和钉子，所述锤头包括敲击部、贮存部和缓冲部，所述敲击部、贮存部和缓冲部依次固连为一体，所述贮存部具有贮存孔，所述钉子设置在贮存孔中，所述腕带通过铰链连接在贮存部外壁。
所述敲击部截面为梯形，实际击打面积小于锤头实际面积，能够在使用时保证视野，避免触碰其他物件。所述贮存孔内壁设有一层橡胶，能够增加摩擦力，有效将钉子锁住，防止钉子脱落。所述缓冲部材质为海绵，置于锁头与使用者手腕之间，能够有效保证击打时手腕的舒适度。所述腕带包括锁头、带体和锁孔，所述锁头与带体铰接，所述锁孔设置在带体上，能够将腕锤牢牢绑在手腕上，防止脱落，保证了手术的安全。
综上所述本发明公开一种用于人工膝关节置换手术的腕锤，本腕锤像手表一样戴在手腕上，省去器械护士的劳动，省时省力，提高手术效率。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
