本实施例中，医用手柄20设有线缆10，线缆10主要用于实现医用手柄20的驱动组件供电和通信等，在一个实施例中，线缆10连接在医用手柄20的一端，第一导线50和第二导线60也设置在线缆10中，从线缆10中接入医用手柄20的内部，减少医用手柄20的线路结构，避免出现线路缠绕的问题，并且方便用户手持医用手柄20进行手术操作。
在一实施例中，电连接件30设于医用手柄20靠近线缆10的一端，第一接收电极40设于医用手柄20远离线缆10的一端。
本实施例中，为了防止线缆10干扰手术操作，医用刀具的刀头和线缆10可以分别位于医用手柄20的两端，将第一接收电极40设置在医用手柄20远离线缆10的一端，使得第一接收电极40靠近医用刀具，有利于接收来自医用刀具释放的经空间磁场耦合的电流，而将电连接件30设置在医用手柄20远离线缆10的一端，可以使得电连接件30和第一接收电极40相隔的距离较远，保证高频发生器经电连接件30至医用刀具这一线路和第一接收电极40至高频发生器这一线路二者相互独立，避免出现相互干扰或短路的情况。
在一个实施例中，第一接收电极40设于医用手柄20的内腔或外壳上。
本实施例中，第一接收电极40可以设置在医用手柄20的内腔中，降低第一接收电极40受损的可能性，保护高压电流伤害操作者，第一接收电极40也可以设置在医用手柄20的外壳上，制作更加简单。
在一个实施例中，电切/电凝医用设备还包括医用刀具，医用刀具与医用手柄连接，且与电连接件30电连接。
本实施例中，电切/电凝医用设备还包括医用刀具，医用刀具的具体类型 可以根据手术类型选择，医用刀具与电连接件30电连接，使得医用刀具可以直接释放高频电流，结构简单，易于实现。
在一个实施例中，医用刀具设置有释放电极，释放电极与电连接件30电连接。
本实施例中，在医用刀具上设有释放电极，医用刀具通过释放电极释放高频电流，高频电流在释放电极附近释放而不用经过整个医用刀具，可以减少对医用刀具的损伤，延长医用刀具的使用寿命，也可以降低高频电流伤害操作者的可能性。
在一个实施例中，释放电极设置在医用刀具的刀头部。
本实施例中，医用刀具主要利用刀头部进行切割、穿刺等操作，将释放电极设置在医用刀具的刀头部，可以充分利用高频电流的特性，显著提高刀头部的切割和穿刺能力，同时降低手术时的出血量。
在一个实施例中，医用手柄20包括驱动组件，驱动组件用于驱动医用刀具，从而可以借助医用手柄20高效灵活地驱动医用道具，示例性地，驱动组件可以是电机或减速机或电机与相关零部件的结合等。
在一个实施例中，医用手柄包括柄体21，柄体21设有收容腔，电连接件设置在柄体21的收容腔中，电连接件30与柄体21之间可以通过卡接或螺接等方式固定，能够有效对电连接件进行收纳、遮蔽，避免电连接件在操作过程中沾染污染物或被用户接触，减少异常情况发生的可能。
在一个实施例中，第一接收电极40设置在收容腔的内部时，也可以避免第一接收电极在操作过程中沾染污染物或被用户接触，减少异常情况发生的可能，第一接收电极40与柄体21之间同样可以通过卡接或螺接等方式固定，提升第一接收电极40与柄体21之间的连接稳定性。
在一个实施例中，柄体21采用绝缘材料，可以是塑料或橡胶等，绝缘材料制成的柄体21不会导电，操作者在进行手术的过程中，若由于线路损坏等原因导致漏电，很容易对持握着医用手柄20的操作者造成伤害，而柄体21采用绝缘材料，可以更好地保护操作者，降低操作者受到伤害的可能性。
以电切/电凝活检设备为例具体说明上述电切/电凝活检设备，医用刀具为活检针，用于对组织进行活检取样，高频发生器产生的高频电流经第一导线50传输至电连接件30，自电连接件30传输至与医用手柄20驱动连接的活检 针，从活检针释放至与活检针接触的组织，实现电切/电凝的功能，再从组织中通过空间磁场耦合至接收电极。当接收电极是设置医用手柄20上的第一接收电极40时，高频电流通过第一接收电极40传输回高频发生器；当接收电极设置在高频发生器的电源地上时，高频电流通过高频发生器的电源地回到高频发生器。提高了活检针的切割和穿刺能力，同时降低活检取样时的出血量，有利于活检取样手术的术后愈合。
以上所述仅为本申请的示例性实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
