具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。
将理解，当一个元件或层被称为在另一元件或层“上”、“连接到”或“耦接到”另一元件或层时，它可以直接在另一元件或层上、直接连接到或耦接到另一元件或层，或者可以存在居间元件或层。相反，当一个元件被称为“直接在”另一元件或层上、“直接连接到”或“直接耦接到”另一元件或层时，不存在居间元件或层。相同的符合标记始终指代相同的元件。在此所用时，术语“和/或”包括一个或多个相关列举项目的任何及所有组合。
将理解，虽然这里可以使用术语第一、第二等描述各种元件、组件、区域、层和/或部分，但这些元件、组件、区域、层和/或部分不应受到这些术语限制。这些术语仅用于将一个元件、组件、区域、层或部分与另一元件、组件、区域、层或部分区别开。因此，以下讨论的第一元件、组件、区域、层或部分可以被称为第二元件、组件、区域、层或部分而不背离本发明的教导。
为便于描述，这里可以使用诸如“在…之下”、“在…下面”、“下”、 “在…之上”、“上”等空间相对性术语来描述如图中所示的一个元件或特征与另一个(些)元件或特征的关系。将理解，空间相对性术语旨在涵盖除图中示出的取向之外，器件在使用或操作中的不同取向。例如，如果附图中的器件被翻转，则被描述为“在”其他元件或特征“之下”或“下面”的元件将会在其他元件或特征“上方”。因此，示例性术语“在…下面”可以涵盖之上和之下两种取向。器件可以以别的方式取向(旋转90度或其他取向)，这里所用的空间相对性描述符被相应地解释。
这里所用的术语仅是为了描述特定实施例，并非要限制本发明。在这里使用时，除非上下文另有明确表述，否则单数形式“一”和“该”也旨在包括复数形式。将进一步理解，当在本说明书中使用时，术语“包括”和/或“包含”表明所述特征、整体、步骤、操作、元件和/或组件的存在，但不排除一个或多个其他特征、整体、步骤、操作、元件、组件和/或其组合的存在或增加。
除非另行定义，这里使用的所有术语(包括技术术语和科学术语)都具有本发明所属领域内的普通技术人员所通常理解的相同含义。将进一步理解，诸如通用词典中所定义的术语，否则应当被解释为具有与它们在相关领域的语境中的含义相一致的含义，而不应被解释为理想化或过度形式化的意义，除非在此明确地如此定义。
本发明的各种实施例提供一种超声外科手术装置，其可连接到超声发生器，从而获取电信号来对组织进行切割和/或止血。超声外科手术装置可包括壳体、换能器组件、导电座及刀头组件。壳体具有分别形成在其近端和远端的近侧开口和远侧开口，近侧开口和远侧开口限定超声外科手术装置的纵向轴线。这里所说的近侧和远侧是以距离超声外科手术装置的操作者的距离来确定的，近侧朝向操作者，而远侧远离操作者。由以下的描述可知，刀头组件穿过远侧开口，而换能器组件穿过近侧开口。导电座设置于壳体内，且导电座可拆卸地连接至换能器组件，刀头组件的第一端穿过远侧开口与换能器组件同轴连接。壳体包括自纵向轴线向下延伸的握持部，该握持部可供操作者握持该手术装置。本发明的超声外科手术装置的握持部设置有一可供超声发生器的输出信号线穿过的通孔。输出信号线穿过该通孔接入壳体内部后，可进一步连接到导电座，从而通过导电座将电信号最终传输到换能器组件。本发明通过壳体介导的走线方式，可克服传统的换能器末端连接电缆时所带来的线缆缠绕的问题， 不仅提高操作便捷度，也有利于延长线缆使用寿命和提高系统连接牢固度。
壳体的握持部可包括底壁和周壁。供输出信号线穿过的通孔可在握持部上灵活设置，例如其可设置在底壁上，或可设置在周壁上朝向操作者的一端。以下具体实施方式中虽然均将通孔设置在底壁上，但本发明并不受限于此。具体设置位置可根据握持部的形状、操作者的操作习惯、壳体内部走线方式等来确定。
请参阅图1至图3，本发明第一方案第一较佳实施方式提供一种超声外科手术装置100。超声外科手术装置100用于连接超声发生器200，以获取电信号来对组织进行切割和/或止血。超声外科手术装置100包括壳体10、换能器组件20、导电座30及刀头组件60。壳体10包括顶壁11、底壁12及连接顶壁11及底壁12的周壁13。周壁13用于握持。导电座30设置于壳体10内，且导电座30可拆卸地连接至换能器组件20。壳体10的周壁13上开设有第一通孔131，刀头组件60的第一端穿过第一通孔131与换能器组件20同轴连接。壳体10的底壁12上开设有第二通孔122，超声发生器200的输出信号线210穿过第二通孔122连接至导电座30，以通过导电座30将电信号传输至换能器组件20。换能器组件20用于将电信号转换成振动信号来带动刀头组件60振动。
具体地，壳体10可由第一壳体101和第二壳体102卡合连接而成。第一壳体101的底壁和第二壳体102的底壁上设有相对应的第一缺口和第二缺口。当第一壳体101和第二壳体102卡合固定后，第一缺口和第二缺口围合形成第二通孔122。
在本实施方式中，壳体10的底壁12上开设有第二通孔122。超声发生器200的输出信号线210穿过第二通孔122连接至导电座30，以输出电信号至导电座30。即超声发生器200的输出信号线210在壳体10的底部伸入至壳体10内，当使用超声外科手术装置100时，使用者握持壳体10的周壁13，而不会发生使用者手臂与输出信号线210接触或者缠绕的可能，不会干扰使用者的操作。另外，超声发生器200的输出信号线210在壳体10的底部伸入至壳体10内，且连接至导电座30，以通过导电座30将电信号传输至换能器组件20，使得换能器组件20将电信号转换成振动信号来带动刀头组件60振动。导电座30固定设置在壳体10内，因此，换能器组件20及刀头组件60的转动不会带 动信号输出线210转动，因此，不会影响刀头组件60转动的顺畅性，也不存在线缆因长期扭转而出现的内部线缆松动的情况，从而缩短了外科手术的手术时间，提高了外科手术的手术效率。
进一步地，超声外科手术装置100还包括手柄70。壳体10的周壁13还设有第三通孔132。换能器组件20套设于手柄70内，且换能器组件20的连接端部伸出手柄70的第一端。手柄70的第一端穿过第三通孔132，以使换能器组件20的连接端部可拆卸地连接至导电座30。手柄70的相对于第一端的第二端位于壳体10的周壁13外部。其中，第三通孔132与第一通孔131相对设置。
需要说明的是，通过转动手柄70，可方便地将换能器组件20安装至导电座30，或将换能器组件20从导电座30上拆卸下来，以对换能器组件20进行更换。当然，手柄70也可以进行握持。
进一步地，换能器组件20包括导电环21及换能器22。导电环21及换能器22的第一端作为换能器组件20的连接端部可旋转拆卸地连接至导电座30。换能器22的第二端收容于手柄70内。
进一步地，超声外科手术装置100还包括连接件50。连接件50包括输入端51及第一输出端52。输入端51连接至输出信号线210，以接收电信号。第一输出端52连接至导电座30，以将电信号输出至导电座30。
需要说明的是，超声外科手术装置100的该连接件还可用于实现输出信号线的循环/重复使用，即连接件的输入端可与超声发生器的输出信号线可拆卸连接。当需要更换超声外科手术装置100时，可以通过将输出信号线210从连接件50的输入端51拆出即可进行更换。该连接件50可如图所示，设置在壳体10内，也可设置在第二通孔120处。超声外科手术装置的刀头组件是更换较为频繁的部件，而超声发生器及其输出信号线并没有必要经常更换。输出信号线与连接件之间的可拆卸连接方式，可以在需要更换刀头组件时将输出信号线拆下，随后再连接到另一连接件上，重复使用。连接件设置在第二通孔处只是出于拆卸便捷性的考虑，事实上，将连接件设置在壳体内，或是由壳体内引出一根固定设置的信号线，再在该信号线末端设置连接件，均可实现重复利用超声发生器的输出信号线的目的。
具体地，输出信号线210的末端可设有接线端子。接线端子与连接件的输 入端可拆卸连接。接线端子与输入端连接时，连通从超声发生器200到换能器组件20的电信号传导通路。输出信号线210通过导电座30将电信号传输至换能器组件20。
进一步地，超声外科手术装置100还包括第一开关40。连接件50还包括第二输出端53。第一开关40连接至第二输出端53，以通过第二输出端53输出第一触发信号至超声发生器200的控制器。当控制器接收到第一触发信号时，输出具有第一功率的电信号至换能器组件20，换能器组件20在第一功率的电信号下带动刀头组件60以第一振幅振动。
需要说明的是，当控制器接收到第一触发信号时，输出具有第一功率的电信号至换能器组件20。具有第一功率的电信号通过导电座30传输至换能器组件20，使得换能器组件20将具有第一功率的电信号转换成振动信号来带动刀头组件60以第一振幅来振动。
请继续参阅图4，本发明第一方案第二较佳实施方式还提供一种超声外科手术装置400。第二较佳实施方式提供的超声外科手术装置400与第一较佳实施方式提供的超声外科手术装置100相似，两者的区别在于：在第二较佳实施方式中，超声外科手术装置400还包括第二开关410。第二开关410连接至第二输出端53，以通过第二输出端53输出第二触发信号至控制器。当控制器接收到第二触发信号时，输出具有第二功率的电信号至换能器组件20，换能器组件20在第二功率的电信号下带动刀头组件60以第二振幅振动。
需要说明的是，当控制器接收到第二触发信号时，输出具有第二功率的电信号至换能器组件20。具有第二功率的电信号通过导电座30传输至换能器组件20，使得换能器组件20将具有第二功率的电信号转换成振动信号来带动刀头组件60以第二振幅来振动。其中，第一开关40及第二开关410在同一时刻只有一个处于闭合状态，即控制器在同一时刻只能接收到第一及第二触发信号中的一个，来使刀头组件60以第一或第二振幅振动。
在本实施方式中，第一开关40与第二开关410分别对应具有第一功率的电信号及具有第二功率的电信号。当第一开关40被启动时，控制器220接收到第一触发信号，控制器220输出具有第一功率的电信号至换能器组件20，使得换能器组件20带动刀头组件60以第一振幅振动。同理，当第二开关410被启动时，控制器220接收到第二触发信号，控制器220输出具有第二功率的 电信号至换能器组件20，使得换能器组件20带动刀头组件60以第二振幅振动。因此，本发明还具有调节刀头组件60的振动幅度的功能。
在本实施方式中，第二开关410可以设置于壳体10上。第二开关410连接至第二输出端53，使第二开关40通过连接件50及输出信号线210输出第二触发信号至超声发生器200的控制器。
在其他的实施方式中，外科手术装置100也可以不包括连接件50。则输出信号线210包括第一信号线、第二信号线及第三信号线。导电座30通过第一信号线连接至超声发生器210，以接收电信号。第一开关40通过第二信号线连接至控制器，以输出第一触发信号至控制器。第二开关410通过第三信号连接至控制器，以输出第二触发信号至控制器。
在另一实施方式中，壳体10内还可设置有电池组件及切换电路。切换电路可连接在电池组件和连接件的输出端、导电座30之间，用于将电池组件与连接件的输出端接通或将电池组件与导电座30接通。本发明的超声外科手术装置在设置有电池组件后，当在手术过程中因线缆不利于走位或线缆牵拉过长导致不便时，可直接将输出信号线210从壳体10上拆下，依靠电池组件提供短期内的信号输出，进一步提高操作灵活性。
请参阅图5，本发明第二方案较佳实施方式提供一种超声外科手术系统500。超声外科手术系统500包括超声发生器200及超声外科手术装置。超声外科手术装置连接至超声发生器200，以获取电信号来对组织进行切割及止血。其中，在本实施方式中，超声外科手术装置为上述第一方案中的第一较佳实施方式提供的超声外科手术装置100。当然，超声外科手术装置也可以为上述第一方案中的第二较佳实施方式提供的超声外科手术装置400。超声手术装置100或400与超声发生器200的连接关系及相互作用关系，以及超声外科手术装置100或400的具体结构已在上述第一方案中进行了详细的描述，在此不再赘述。
在本实施方式中，超声外科手术系统500包括超声外科手术装置100。超声外科手术装置100包括壳体10。其中，壳体10的底部12上开设有第二通孔122。超声发生器200的输出信号线210穿过第二通孔122连接至导电座30，以输出电信号至导电座30。即超声发生器200的输出信号线210在壳体10的底部伸入至壳体10内，当使用超声外科手术装置时，使用者握持壳体10的周 壁13，而不会发生使用者手臂与输出信号线210接触或者缠绕的可能，不会干扰使用者的操作。另外，超声发生器200的输出信号线210在壳体10的底部伸入至壳体10内，且连接至导电座30，以通过导电座30将电信号传输至换能器组件20，使得换能器组件20将电信号转换成振动信号来带动刀头组件60振动。因此，换能器组件20的转动不会带动信号输出线210转动，因此，不会影响刀头组件60转动的顺畅性。
以上是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
