具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
本发明提供一种手术器械，包括操作部以及依次相连的探杆1、转动部5和执行器17；操作部与转动部5相连，操作部与执行器17相连；操作部设置为能够控制转动部5带动执行器17相对于探杆1转动并能够控制执行器17执行操作，转动部5与探杆1之间通过转动销11铰连接。
本发明所述的手术器械，在手术时候，探杆1可以带着转动部5和执行器17探入病灶内部的大概位置。通过转动销11实现执行器17相对于探杆1的转动，以此来寻找需要手术的具体的部位以进行手术，因为旋转动作仅仅依靠转动销11的铰接实现，所以转动部5的长短决定了旋转半径；转动5小就可以减小旋转半径；在探入病灶的通道狭窄且进入病灶的路径与探杆1所呈的角度较大时，只有转弯半径较小的手术器械才可探入病灶 进行手术。本发明所述的手术器械，利用转动部和探杆之间的铰连接以使得转动部可以在转动部较短的情况下带动执行器进行一定角度的弯曲，缩小了转弯半径；该手术器械扩大了手术可操作的范围，对于临床治疗具有积极的意义。
为了实现操作部对转动部5的控制，本发明提供一种操作部控制转动部5的方式，如图2和图3所示，操作部可包括能够沿着探杆1的长度方向滑动的第一操作器2；第一操作器2可通过连杆4与转动部5相连，连杆4的两端可分别铰接第一操作器2和转动部5，以使得第一操作器2通过推拉连杆4而带动转动部5以及执行器17相对于探杆1转动。
在本方案中，连杆4与第一操作器2可通过第一连接销9进行铰接，连杆4与转动部5可通过第二连接销10进行铰接；本方案利用了曲柄滑块的结构，实现通过操纵第一操作器2而实现对转动部5旋转的反向控制。本方案所用的结构简单，可利用较低的成本获得。
如图3中所示，探杆1可为中空件，第一操作器2可设置在探杆1的内部，连杆4可设置在第一操作器2的端部。本发明所述的结构用于手术器械，活动范围位于病体内，第一操作器2可在探杆1内部滑动，使得病体不因第一操作器2的运动而造成二次损伤。
探杆1可为圆杆，第一操作器2可设置为外侧能够与探杆1的内侧相贴合滑动的滑杆。中空探杆1的内侧轮廓可与第一操作器2的外侧轮廓大致相同以形成用于第一操作器2滑动的滑道，这样，充分利用手术器械本身的结构特点，简化结构和制造工艺，减少制造成本。
为了实现操作部对转动部5的控制，本发明提供另一种操作部控制转动部5的方式，如图4和图5中所示，操作部可包括设置有凸轮状滑道的转轮204，转轮204可通过轴承设置在中空的探杆1与转动部5相连的一端的端部，转动部5上可设置有与凸轮状滑道相嵌合的配合端206以使得转轮204转动而带动配合端206沿着凸轮状滑道滑动，从而使得配合端206 摆动，进而使得转动部5沿着所述转动销11相对于探杆1转动。凸轮状的滑道可使得配合端206随着转轮204的转动严格按照滑道变化轨迹进行上下摆动，因此，在实现转动部5旋转的同时，具有较高的精确性。
如图5中所示，操作部可包括设置在直状中空的探杆1的内部的用于转动转轮204的第三操作器202，第三操作器202可为与转轮204相连的直杆。通过转动第三操作器202，即可实现对转轮204进行相同角度的旋转，进而精确控制转动部5的旋转角度，由此传动直接且精确，并易于控制操作。
根据上述两种操作部控制转动部5的方式，如图3或图5所示，操作部可包括设置在转动部5内且能够沿转动部5的轴向滑动的滑动块12和设置在中空的探杆1的内部的钢丝绳3；钢丝绳3可通过滑动块12与用于控制执行器17执行操作的滑动销8相连，以使得通过拉紧或者松开钢丝绳3控制滑动块12滑动进而控制滑动销8的滑动从而控制执行器17执行操作。转动部5的轴向即为执行器17相对于转动部5设置的方向。
钢丝绳3是多个钢丝股相互绞合而成的条状物，具有较高的强度和刚度，在拉伸弯折过程中不易损坏，且原料易得，造价较低，容易实现大量生产；另外，也可使用钛合金丝拧成的绳体，但是造价较高；同时棉麻丝拧成的绳状物强度较低，在长期手术使用中容易断裂，易于造成不可预估的后果。
执行器17可包括第一执行器6和第二执行器7，第一执行器6和第二执行器7上均可设置有用于装设钳口销13的钳口孔14，第一执行器6和第二执行器7上可分别设置有滑槽15以使得滑动销8在滑槽15内滑动而带动第一执行器6和第二执行器7的开闭。
本方案所述的执行器17用于夹取物体，在钢丝绳3松开的时候，第一执行器6和第二执行器7会因为重力原因分开，在夹取的时候，钢丝绳3拉紧，进而使得滑动销8滑动，以实现执行器17的闭合，整个装置结构简 单，在降低成本的同时也容易实现整个装置的制造的精确度。
第一执行器6和第二执行器7的结合端可插入转动部5内，转动部5上可设置有用于滑动销8滑动的滑道。第一执行器6和第二执行器7的端部可插入转动部5的内部，以实现执行器17的稳定运行，而转动部5上设置的滑道可便于滑动销8的稳定滑动，以实现执行器17的稳定操作。
手术器械可包括用于操控操作部的操作机构。现有的手术一般通过医生操刀而实现对执行器的控制，也就是说，医生通过控制便于手持的操作机构来控制操作部，进而控制执行器17；而另外一些手术需要的精度极高，需要电脑的精确操控，电脑通过控制操作机构来控制操作部，进而控制执行器17进行手术。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于此。在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型。包括各个具体技术特征以任何合适的方式进行组合。为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。但这些简单变型和组合同样应当视为本发明所公开的内容，均属于本发明的保护范围。
