本发明涉及医用外科手术器械，具体涉及一种单电机电动手术器械手持组件，以及使用该手持组件的单电机电动手术器械。
背景技术
外科手术中通常使用吻合器实现对组织的切除和创面的封闭。吻合器包括直线切割吻合器、管型吻合器、腔镜下直线切割吻合器等。这些吻合器可以用于切除肺、肠、胃的病变组织，同时对创面进行封闭。在手术过程中，吻合器的末端执行器对组织进行夹持和挤压，然后利用切割刀切割组织，对于产生的创面，则利用吻合钉进行快速的缝合。吻合器的使用缩短了手术时间，提高了手术的成功率，而且术后恢复快。
目前使用的吻合器主要通过有手动操作和电动操作两种。手术过程中，须用吻合器前端夹持住待切割组织，做好击发前的准备。对于手动操作的吻合器，在击发吻合器的过程中，医生须在悬空握持住吻合器的同时按动手柄，完成击发。整个击发过程中，手部提供支撑和按压两种力量，容易出现手部的抖动导致的吻合器抖动。同时，手动击发施力不够稳定和均匀，尤其是对于直线切割吻合器，击发时需要多次按压手柄才能完成整个击发过程，在每次按压手柄动作后，须要松开手柄再进行下一次手柄的按压，这个松开手柄的过程使得切割刀停止前进，而且推钉片也停止运动，对于吻合钉的推力也迅速下降至零。导致在吻合钉成型存在缺陷，且切割刀的切割创面不平顺，尤其是放松手柄的位置上述问题更加明显。
而对于电动吻合器来说，医生只需稳定握持住吻合器，通过按钮使切割刀和吻合钉运动，能够实现切割刀的平稳运动以及吻合钉的平稳连续缝合，从而有效保证了切割效果。有对比研究表明：相对于使用手动吻合器，使用电动吻合器的出血并发症减少近一半，同时患者所支付的住院费用降低了近10％，出院时间提前了一天(Impact of Powered and Tissue-Specific Endoscopic Stapling Technology on Clinical and Economic Outcomes of Video-Assisted Thoracic Surgery Lobectomy Procedures:A Retrospective,Observational Study，Daniel L.Miller等,Advances in Therapy，(2018)35:707–723)。电动吻合器的操作动作包括钉仓组件的闭合和击发、钉仓组件的摆头运动和钉仓组件绕自身轴的旋转，钉仓组件运动形 式多，因而现有的电动吻合器通常采用带有多个电机的动力源来分别控制各个动作，吻合器中还需要配套设置对应的动力传递系统，导致的电动吻合器成本高昂，重量大、结构复杂。
