本发明涉及用于对生物体组织进行处理的处理器具及该处理器具用的手柄。
背景技术
例如在美国专利第7,156,846号说明书中公开了一种具有在将生物体组织保持于一对钳构件之间的状态下切断该保持着的生物体组织的结构的处理器具。为了减轻使用者的负担该处理器具具有用于维持相对闭合了一对钳构件的状态的机构。
而且，例如在连续地对膜组织、实质组织进行处理的情况下，重复以下这样的处理：解除闭合了一对钳构件的状态并在刚使一对钳构件前进到前方之后就闭合一对钳构件并切断生物体组织。
在该情况下，在相对打开一对钳构件的情况下，需要解除维持闭合的状态的机构。因此，在进行这种连续的重复操作的情况下，存在成为使用者的负担的忧虑。
因而，期望在进行连续地切开生物体组织等重复操作的情况下能够减轻负担的处理器具及处理器具用手柄。

具体实施方式
以下，参照附图说明用于实施本发明的方式。
参照图1A～图5D说明第1实施方式。
如图1A所示，该实施方式的治疗处理系统10包括处理器具(治疗用处理器具)12和能量源(控制部)14。在此，作为处理器具12，以例如用于穿过腹壁进行处理的、牵引线型的外科用处理器具为例进行说明。在能量源14上，利用线缆18b连接有具有踏板16a的脚踏开关(也可以是手动开关)16。另外，处理器具12与能量源14利用线缆18a相连接。
如图1A～图2B所示，处理器具12包括由操作者支承的手柄(处理器具用手柄)20、从手柄20沿着中心轴线C(长度轴线L)延伸出的轴24、第1末端执行器26以及第2末端执行器28。而且，通过手术者操作脚踏开关16的踏板16a，从而在该实施方式中，切换能量从能量源14向处理器具12的第1末端执行器26(具体地说为后述的第1量输出部44及第2能量输出部54)的供给的接通/断开。当按压着踏板16a时，根据适当地设定了能量源14后的状态(控制了能量输出量、能量输出时机等的状态)从能量源14输出能量。若解除踏板16a的按压，则强制使能量的输出停止。
如图2A和图2B所示，轴24包括内筒32和以能够滑动的方式配置于该内筒32的外侧的外筒34。如图3A和图3B所示，内筒32利用其基端部固定于手柄20。外筒34能够沿着内筒32的轴向滑动。
如图1A、图2A以及图2B所示，第1末端执行器26配置于轴24的顶端。第1末端执行器26具有第1把持部26a和第2把持部26b。第1把持部26a包括第1钳构件42、具有第1把持面44a的第1能量输出部44以及由第1钳构件42和第1能量输出部44形成并引导后述的刀具(移动体)62、即第2末端执行器28的引导槽(第2末端执行器配置部)46。第2把持部26b包括第2钳构件52、具有第2把持面54a的第2能量输出部54以及由第2钳构件52和第2能量输出部54形成并引导后述的刀具62、即第2末端执行器28的引导槽(第2末端执行器配置部)56。第1钳构件42及第2钳构件52能够相对接近及远离。第1能量输出部44设于第1钳构件42，第2能量输出部54设于第2钳构件52，第1量输出部44及第2能量输出部54的把持面44a、54a彼此相对。第2钳构件52和第2能量输出部54能够在相对于第1钳构件42和第1能量输出部44远离的打开状态与相对于第1钳构件42和第1能量输出部44接近的闭合状态之间相对开闭。优选的是，第1钳构件42及第2钳构件52分别整体具有绝缘性。第1量输出部44及第2能量输出部54分别使用了例如高频电极、加热器等并连接于能量源14。因此，利用热能对配置于第1量输出部44及第2能量输出部54的把持面44a、54a之间的生物体组织进行处理。
第1钳构件42的基部42a固定于轴24的内筒32的顶端。另一方面，第2钳构件52的基部52a利用配置在与轴24的轴向正交的方向上的支承销36以能够转动的方式支承于轴24的内筒32的顶端。第2钳构件52通过绕支承销36转动而能够相对于第1钳构件42开闭。而且，该第2钳构件52例如被板簧等弹性构件38施力以相对于第1钳构件42打开。
而且，使外筒34相对于内筒32滑动，能够利用外筒34的顶端覆盖第1钳构件42及第2钳构件52的基部42a、52a。在该状态下，如图2A和图2B所示，克服弹性构件38的作用力而相对于第1钳构件42闭合第2钳构件52。另一方面，若从利用外筒34的顶端覆盖了第1钳构件42及第2钳构件52的基部42a、52a的状态使外筒34向内筒32的基端侧滑动，则如图2A所示，在弹性构件38的作用力的作用下，第2钳构件52相对于第1钳构件42打开。
第2末端执行器28具有薄板状的刀具(治疗辅助器具)62。在轴24的内筒32的内侧，以能够沿着其轴向移动的方式配置有驱动杆64。
刀具62在其顶端形成有刃62a，在基端固定有驱动杆64的顶端。在该刀具62的顶端与基端之间形成有长槽62b。在该长槽62b内，向与轴24的轴向正交的方向延伸的移动限制销66固定于轴24的内筒32。在刀具62的长槽62b的一端、另一端以及一端与另一端之间的至少3个部位形成有用于卡定移动限制销66、并控制刀具62的移动的卡定部62c。因此，若操作后述的驱动杆82，则刀具62借助驱动杆64沿着移动限制销66移动。此时，刀具62笔直地移动，并配置于引导槽46、56。
另外，为了将刀具62配置于引导槽46、56，长槽62b和移动限制销66未必是必需的。
手柄20具有手柄主体20a，并形成为手术者易于握持的形状，例如在本实施方式中形成为大致L字状。手柄主体20a具有供轴24的基端配置的一端(顶端)22a和作为由手术者握持的握持部的另一端22b。在手柄主体20a的一端(顶端)22a配置有轴24的基端。例如从手柄主体20a的与该轴24大致同轴上的基端延伸出有上述线缆18a。
手柄主体20a的另一端22b是由手术者握持的握持部。在手柄主体20a上，在一端22a与另一端22b之间，以与该另一端22b排列设置的方式配置有处理部开闭杆(第1操作输入体)72。在本实施方式中，在手柄主体20a的另一端22b的前侧配置有处理部开闭杆72。向开闭杆72中输入操作以使得第1末端执行器26相对于处理对象的生物体组织进行动作。即，该开闭杆72用于使第1末端执行器26进行动作。
处理部开闭杆72在手柄主体20a的大致中央连结于轴24的外筒34(参照图2A和图2B)的基端。若使该处理部开闭杆72相对于手柄主体20a的另一端22b接近及远离，则外筒34沿着其轴向移动。
处理部开闭杆72具有枢支轴74、操作部76以及一对爪部78。处理部开闭杆72在手柄主体20a的内部能够利用枢支轴74向图3A所示的第1方向α(相对于手柄主体20a的另一端22b接近的接近方向)和第2方向β(相对于手柄主体20a的另一端22b远离的远离方向)转动。操作部76从手柄主体20a的下端向外侧突出，并配置于手柄主体20a的另一端22b的前侧。因此，能够使操作部76相对于手柄主体20a的另一端22b远离(参照图3A)及接近(参照图3B)。
一对爪部78位于处理部开闭杆72的上端并以支承外筒34的基端的方式形成为大致Y字状，该一对爪部78在手柄主体20a的内部与配置于轴24的外筒34的基端的销34a相卡合。销34a相对于外筒34的外周面向与中心轴线C正交的外方延伸出来。因此，配置于外筒34的基端的销34a以能够相对于处理部开闭杆72的上端的爪部78移动的方式支承于处理部开闭杆72的上端的爪部78。因此，外筒34利用处理部开闭杆72的操作部76的操作而能够相对于手柄主体20a和内筒32移动。
该处理部开闭杆72在手柄主体20a的大致中央的部分连结于轴24的后述的外筒34的基端。因此，若使处理部开闭杆72接近手柄主体20a的另一端22b，则相对于手柄主体20a使轴24的后述的外筒34沿着其轴向前进。另一方面，若使处理部开闭杆72远离手柄主体20a的另一端22b，则相对于手柄主体20a使外筒34沿着其轴向后退。
如图1A、图3A以及图3B所示，在手柄主体20a上，在处理部开闭杆(第1操作输入体)72的前侧(比处理部开闭杆72接近第1末端执行器26的位置)配置有使作为第2末端执行器28的刀具62移动的驱动杆(第2操作输入体)82。即，驱动杆82支承在比开闭杆72接近手柄主体20a的一端22a的位置。
刀具驱动杆82在手柄主体20a的大致中央与配置于轴24的内侧的驱动杆64的基端相连结。若使该刀具驱动杆82相对于手柄20的另一端22b接近及远离，则驱动杆64和刀具62沿着其轴向移动。而且，向驱动杆82中输入操作以使得与第1末端执行器26不同的第2末端执行器28相对于生物体组织进行动作并且解除卡合于手柄主体20a的后述的连动体112的卡合。即，该驱动杆82用于使第2末端执行器28进行动作。
如图3A～图4C所示，驱动杆82具有枢支轴84、供食指或中指勾挂的操作部86、抵接于开闭杆72的一对抵接面(第1抵接部)88、抵接于后述的连动体112的突起112a的突起(第2抵接部)90以及爪部92。驱动杆82能够利用配置于手柄主体20a的内部的枢支轴84向图3A所示的第1方向γ(相对于手柄主体20a的另一端22b接近的接近方向)和第2方向δ(相对于手柄主体20a的另一端22b远离的远离方向)转动。驱动杆82的操作部86从手柄主体20a的下端向外侧突出，并配置于手柄主体20a的另一端22b的前侧。因此，能够使驱动杆82的操作部86相对于手柄主体20a的另一端22b接近(参照图3B中的虚线)及远离(参照图3B中的实线)。另外，爪部92位于驱动杆82的上端，在手柄主体20a的内部与配置在固定于驱动杆64的基端的连结构件94上的销98a相卡合。
如图4B所示，连结构件94包括：具有配置于驱动杆64的基端的贯穿孔96a的主体96、和向与贯穿孔96a的中心轴线C正交的外侧方向延伸出的销98。连结构件94固定于驱动杆64的基端。如图4A所示，销98向与刀具62的平面正交的方向延伸出来，并与位于驱动杆82的上端的爪部92相卡合。
因此，能够使驱动杆82的操作部86相对于手柄20的另一端22b接近及远离。操作驱动杆82的操作部86，若借助连结构件94使驱动杆64前进，则刀具62、即第2末端执行器28前进，若借助连结构件94使驱动杆64后退，则刀具62、即第2末端执行器28后退。此时，刀具62、即第2末端执行器28沿着第1引导槽及第2引导槽(流路、流体喷出槽)46、56移动。特别是当刀具62的顶端前进至极限时，刀具62的顶端(刃62a)位于比引导槽46、56的顶端稍微靠基端侧的位置。当刀具62的顶端后退至极限时，刀具62的顶端设定为配置于内筒32的顶端的内侧或引导槽46、56的基端的位置且不与生物体组织相接触。
如图5A～图5D所示，手柄主体20a具有支承部104，该支承部104具有供后述的连动体112的嵌合部(卡合部)116载置而嵌合或卡合的嵌合座部(卡合座部)102。嵌合座部102的纵截面形成为大致L字状。嵌合座部102的手柄主体20a的内部侧形成为凹状，下端侧(外侧)形成为凸状。
在开闭操作杆72上，利用旋转轴114支承有连动地运动的连动体112。旋转轴114支承于连动体112的基端。连动体112能够利用旋转轴114向第1方向ε和第2方向δ转动。连动体112伴随着向开闭杆(第1操作输入体)72输入操作而连动地运动，若开闭杆72向第1方向α转动，则在连动体112向第1方向ε或第2方向δ转动而卡合于手柄主体20a时限制开闭杆72向第2方向β转动。
连动体112在其顶端具有能够嵌合于手柄主体20a的嵌合座部102的嵌合部116。在开闭操作杆72与连动体112之间配置有朝向手柄主体20a的嵌合座部102对连动体112的嵌合部116施力的弹性体118。
如图5A～图5C所示，连动体112具有朝向手柄主体20a的下端突出的突起112a。换言之，连动体112具有以抵接于驱动杆(第2操作输入体)82的突起90的方式朝向驱动杆82突出的突起112a。
如图5A～图5D所示，驱动杆82的突起90位于比一对抵接面88的基端侧边缘部接近操作部86的位置，并形成于一对抵接面88之间。因此，在突起90与抵接面88之间形成有空间88a。另外，如图5C所示，连动体112未抵接于驱动杆82的一对抵接面88，刀具驱动杆82的突起90与连动体112的突起112a相抵接。而且，当在连动体112嵌合于手柄主体20a的状态下使驱动杆82向第1方向γ转动后，驱动杆82比抵接于开闭杆72先抵接于连动体112。抵接面88形成为例如平面凸轮。对图5A所示的驱动杆82的抵接面88与开闭杆72的操作部76之间相接触的情况与图5C所示的驱动杆82的抵接面88与开闭杆72的操作部76之间相接触的情况进行比较，前者的情况下开闭杆72的操作部76与驱动杆82的枢支轴84之间的距离小。而且，形成为平面凸轮的抵接面88在使图5C所示的位置的开闭杆72向图5A所示的位置返回时调整为能够一边尽量维持闭合了第1把持部26a及第2把持部26b的状态、一边使刀具62的刃62a向轴24的内侧移动。因此，能够防止在未把持生物体组织的状态下刀具62配置于生物体组织之间。即，通过适当地设定抵接面88的形状，能够适当地调整第1末端执行器26与第2末端执行器28之间的位置关系。
接着，使用图5A～图5C说明本实施方式的治疗处理系统10的作用。
从开闭杆72和刀具驱动杆82位于图5A所示的位置的状态开始进行操作，以使开闭杆72的操作部76向第1方向α转动，使开闭杆72的操作部76接近手柄主体20a的另一端22b。此时，连动体112被弹性体118向手柄主体20a的支承部104施力。因此，连动体112的嵌合部116一边抵接于手柄主体20a的支承部104一边接近支承部104的嵌合座部102。即，伴随着开闭杆72的移动，支承于旋转轴114的连动体112的嵌合部116接近手柄主体20a的嵌合座部102。此时，连动体112能够利用旋转轴114相对于开闭杆72向第2方向δ移动。然后，如图5B所示，连动体112的嵌合部116嵌合或卡合于手柄主体20a的嵌合座部102。此时，连动体112利用旋转轴114相对于开闭杆72向第1方向ε转动。
在此，为了维持连动体112的嵌合部116嵌合于嵌合座部102的状态，弹性体118对连动体112施加了作用力。因此，限制了使开闭杆72向第2方向β转动。
当开闭杆72向第1方向α转动后，外筒34相对于内筒32前进，第2钳构件52相对于第1钳构件42闭合。即，当开闭杆72向第1方向α转动后，能够使第1末端执行器26进行动作。因此，能够利用能量输出部44、54的把持面44a、54a把持生物体组织。若在该状态下按压脚踏开关16的踏板16a，则如图1B所示，利用来自能量输出部44、54的热能对能量输出部44、54之间的生物体组织进行处理。
在这种处理之后，使驱动杆82向第1方向γ转动而朝向开闭杆72接近。此时，如图5C所示，刀具驱动杆82比抵接于开闭杆72先抵接于连动体112。具体地说，驱动杆82的突起90抵接于连动体112的突起112a。然后，克服弹性体118的作用力使连动体112向绕旋转轴114的第2方向δ弹起，解除嵌合部116嵌合或卡合于嵌合座部102的状态。然后，驱动杆82的一对抵接部88抵接于开闭杆72。
即，在驱动杆82的一对抵接部88抵接于开闭杆72时，已经使连动体112向绕旋转轴114的第2方向δ转动而解除并结束了嵌合部116嵌合或卡合于嵌合座部102的状态。
若使驱动杆82向第1方向γ转动，则如图4A所示，刀具62、即第2末端执行器28借助驱动杆64前进。因此，能够利用刀具62的刃62a将使用热能处理后的生物体组织切断。
在此，由于利用驱动杆82使连动体112朝向手柄主体20a的内部向绕旋转轴114的第2方向δ弹起，因此连动体112的嵌合部116是未嵌合于手柄主体20a的嵌合座部102的状态。因此，能够使开闭杆72向第2方向β转动。而且，若使开闭杆72向第2方向β转动，则抵接于开闭杆72的驱动杆82也向第2方向δ转动。而且，与开闭杆72连动的连动体112的嵌合部116相对于手柄主体20a的支承部104的嵌合座部102远离。
因而，相对于生物体组织抽拔并去除刀具62的刃62a，并且第2钳构件52相对于第1钳构件42打开。即，第2末端执行器28进行动作，并且第1末端执行器26也进行动作。
使打开状态的第1钳构件42及第2钳构件52相对于生物体组织向前方前进，使开闭杆72接近手柄主体20a的另一端22b而闭合第1钳构件42及第2钳构件52，踩下脚踏开关16的踏板16a而利用热能对生物体组织进行处理。之后，操作驱动杆82而利用刀具62切断生物体组织。再之后，一边使开闭杆72朝向第2方向β转动一边将刀具62拉入轴24的内部。依次重复这种操作，不仅是能量输出部44、54之间的生物体组织，还能够连续地接合、切断位于其前方的生物体组织。
简要说明上述手柄20的动作。首先，相对于由操作者保持的手柄主体20a，使能够向第1方向α及第2方向β转动的第1操作输入体72向第1方向α转动而使第1末端执行器26进行动作从而对生物体组织发挥第1末端执行器26所具有的功能。接着，伴随着使第1操作输入体72转动而连动地使能够向第3方向ε及第4方向δ转动的连动体112适当地转动而卡合于手柄主体20a，维持使第1末端执行器26进行动作而对生物体组织发挥功能的状态。这样，在维持着使第1末端执行器26进行了动作的状态的状态下，使能够向第5方向γ及第6方向δ转动的第2操作输入体82向第5方向γ转动而使第2末端执行器28进行动作从而对生物体组织发挥第2末端执行器28所具有的功能。然后，伴随着使第2操作输入体82向第5方向γ转动而使连动体112向第4方向δ转动，解除连动体112相对于手柄主体20a的卡合。最后，伴随着使第1操作输入体72向第2方向β转动而停止发挥第1末端执行器26所具有的功能，并且使第2操作输入体82向第6方向δ转动，停止发挥第2末端执行器28所具有的功能。
如以上所说明，根据该实施方式，可以说起到以下效果。
在使以能够相对于手柄主体20a转动的方式支承于手柄主体20a的开闭杆72向第1方向α转动而利用第1把持部26a及第2把持部26b保持着生物体组织之后，踩下脚踏开关16的踏板16a，能够进行对把持在能量输出部44、54之间的生物体组织施加热能的处理。通过在该状态下操作驱动杆82，从而能够解除与开闭杆72连动的连动体112卡合于手柄主体20a的状态，并且能够利用刀具62切断生物体组织。
因而，用手术者的一只手仅靠开闭操作杆72和驱动杆82的操作就能够完成如下一连串(1个循环)的动作，即，能够不必进行多余的操作地来进行这一连串动作：将生物体组织把持在一对把持部26a、26b之间并从能量输出部44、54向把持着的生物体组织输出能量而进行处理(利用第1末端执行器26进行处理)，进行利用刀具62切断处理后的生物体组织的处理(利用第2末端执行器28进行处理)，一边解除一对把持部26a、26b之间的生物体组织的把持一边拉入刀具62。
而且，由于能够利用驱动杆82的操作来解除嵌合于手柄主体20a的状态的连动体112嵌合，因此在该实施方式中，能够使连动体112不仅与开闭杆72连动，还与驱动杆82连动。因而，例如能够省去在使驱动杆82前进而切断生物体组织并后退之后解除开闭杆72嵌合于手柄主体20a的状态这样的工夫。因此，能够高效地进行针对生物体组织的使用了能量的处理及该生物体组织的切断这样的一连串的操作，能够较大地提高对位于处理、切断的生物体组织的前方的生物体组织同样地进行处理及切断时的操作的效率性。
另外，当在连动体112嵌合于手柄主体20a的状态下使驱动杆82向第1方向γ转动后，只要比使驱动杆82抵接于开闭杆72先使连动体112抵接于刀具驱动杆82，就不必需要突起90、112a两者或一者。
图6A所示的例子是在驱动杆82上形成有突起90、在连动体112上不存在突起的例子。
图6B所示的例子是在驱动杆82上不存在突起、在连动体112上形成有突起112a的例子。
图6C所示的例子是在驱动杆82和连动体112两者上不存在突起的例子。
而且，在图6A～图6C中，示出了在处理部开闭杆72与连动体112之间并非必须需要上述弹性体118(参照图5A－图5C)。
接着，使用图7A～图7C说明第2实施方式。该实施方式是第1实施方式的变形例，对与第1实施方式中说明的构件相同的构件或具有相同的功能的构件标注相同的附图标记，并省略详细的说明。
如图7A和图7B所示，该实施方式的第1末端执行器26的把持部26a、26b这两者运动。另外，取代刀具(冷切刀具)62，作为第2末端执行器28使用另外的刀具(移动体)162。虽未图示，但是在刀具162的内部配置有若流入电流则转换为热量的作为加热电阻体发挥作用的传热线162a。传热线162a经由驱动杆64的内部的管路64a连接于能量源14。若电流从能量源14向刀具(热切刀具)162的传热线162a流动，则能够比第1实施方式中说明的刀具(冷切刀具)62容易地利用该热能切断生物体组织。
第1钳构件42及第2钳构件52的基部42a、52a均在与轴24的轴向正交的方向上利用配置于内筒32的顶端部的支承销36a、36b以能够转动的方式支承于轴24的内筒32的顶端部。这些支承销36a、36b彼此平行地配置于内筒32的顶端部。通过使基部42a、52a绕支承销36a、36b转动，从而第1钳构件42及第2钳构件52能够使钳构件42、52彼此开闭。如图7A和图7B所示，在配置于内筒32的顶端部的支承销36a、36b的外周上配置有弹性构件38a、38b。因此，第1钳构件42及第2钳构件52分别被向打开的方向施力。
因此，若操作开闭杆72而使外筒34的顶端从手术者向远位侧移动(前进)，则利用外筒34的顶端施加有力以使得基部42a、52a闭合。这样的话，克服弹性构件38a、38b的作用力使第1钳构件42及第2钳构件52闭合。另一方面，若操作开闭杆72而使外筒34的顶端相对于手术者向近位侧移动(后退)，则由外筒34的顶端闭合基部42a、52a的力丧失，即，在弹性构件38a、38b的作用力的作用下，第1钳构件42及第2钳构件52打开。
另外，在本实施方式中，第1实施方式中说明的驱动杆82为了使刀具162移动而发挥作用。
另外，在该实施方式中，切换能量从能量源14向处理器具12的第1末端执行器26(具体地说为后述的第1量输出部44及第2能量输出部54)的供给的接通/断开，并且切换用于向第2末端执行器28(具体地说为刀具162)流入电流的能量的供给的接通/断开。
简单地说明本实施方式的治疗处理系统10的作用。对于第1实施方式中说明的内容，适当地省略记载。
若使开闭杆72的操作部76接近手柄主体20a的另一端22b，则如图5B所示，连动体112的嵌合部116嵌合于手柄主体20a的嵌合座部102。此时，限制了开闭杆72向第2方向β转动。
当开闭杆72向第1方向α转动后，外筒34相对于内筒32前进，第1把持部26a及第2把持部26b闭合。即，当开闭杆72向第1方向α转动后，第1末端执行器26进行动作。因此，能够利用能量输出部44、54的把持面44a、54a把持生物体组织。若在该状态下按压脚踏开关16的踏板16a，则利用热能对能量输出部44、54之间的生物体组织进行处理。
在这种处理之后，使驱动杆82向第1方向γ转动而接近开闭杆72，解除连动体112的嵌合部116嵌合于手柄主体20a的嵌合座部102的状态。然后，驱动杆82的一对抵接部88抵接于开闭杆72。
若使驱动杆82向第1方向γ转动，则如图4A所示，刀具162前进。即，当驱动杆82向第1方向γ转动后，第2末端执行器28进行动作。因此，能够利用刀具162进一步使用热能对使用热能处理后的生物体组织进行凝固、切开等处理。
而且，若使开闭杆72向第2方向β转动，则抵接于开闭杆72的驱动杆82也向第2方向δ转动。而且，与开闭杆72连动的连动体112的嵌合部116相对于手柄主体20a的嵌合座部102远离。
因而，相对于生物体组织抽拔并去除刀具162，并且第1把持部26a及第2把持部26b打开。使打开状态的第1把持部26a及第2把持部26b相对于生物体组织向前方前进，使开闭杆72接近手柄主体20a的另一端22b并踩下脚踏开关16的踏板16a，之后，操作驱动杆82并利用超声波能量对生物体组织进行处理。再之后，一边使开闭杆72朝向第2方向β转动一边将刀具162拉入轴24的内部。依次重复这种操作，不仅是能量输出部44、54之间的生物体组织，还能够连续地接合、切断位于其前方的生物体组织。
如图8A和图8B所示，也优选的是，多个加热器166配置于刀具164。即，优选的是，第2末端执行器28具有刀具164和加热器166。另外，加热器166既可以沿长度方向适当地分割，也可以成一体。加热器166经由通电线166a连接于能量源14。若从能量源14经由配置于驱动杆64的内部的管路64a的内侧的通电线166a向加热器166供给电力，则加热器166发热，将其热量向刀具164传递。若电流从能量源14向刀具(热切刀具)164的通电线166a流动，则能够比第1实施方式中说明的刀具(冷切刀具)62容易地利用该热能切断生物体组织。另外，刀具164与刀具162相同地进行动作。
在该实施方式中，说明了作为第2末端执行器28使用刀具(热切刀具)162、164的例子，但是如图9A～图9C所示，也可以取代刀具162、164而使用被传递超声波振动的探头172。在探头172的基端或驱动杆64的基端配置有未图示的超声波振子，能够将来自能量源14的电能转换为超声波振动。因此，能够使用超声波振动能量并利用探头172对使用热能处理后的生物体组织进一步进行凝固、切开等处理。
即，该实施方式的第2末端执行器28能够进一步使用其他能量对使用热能处理后的生物体组织进行生物体组织的切开等处理。
接着，使用图10A～图10C说明第3实施方式。该实施方式是第1实施方式及第2实施方式的变形例，对与第1实施方式及第2实施方式中说明的构件相同的构件或具有相同的功能的构件标注相同的附图标记，并省略详细的说明。
如图10A～图10C所示，在该实施方式中，作为第2末端执行器28，使用作为大致U字状的针的外科缝合器180。优选的是，外科缝合器180例如由生物体吸收性材料形成。
如图10A和图10C所示，在第2钳构件52与能量输出部54的背面之间的盒(第2末端执行器配置部)178内配置有多个缝合器180。
如图10C所示，在第2钳构件52的、用于放出外科缝合器(吸收性构件)180的盒178内，以进退自如的方式收纳有具有倾斜面182a的推杆182。另外，该实施方式的推杆182配置于第1实施方式中说明的驱动杆64的顶端。
在盒178内，以使腿部180a朝向配置于第1钳构件42的能量输出部44、并且能够向第1钳构件42的能量输出部44的表面的方向突出的方式收纳有具有一对腿部180a和连结腿部180a彼此的臂180b的缝合器180。在能量输出部54内，与推杆182相对地形成有引导槽(开口)184。在引导槽184内，以能够相对于引导槽184滑动的方式配置有缝合器推动件186，该缝合器推动件186具有与推杆182的倾斜面182a相同地倾斜的倾斜面186a。
如图10B和图10C所示，在配置于第1钳构件42的能量输出部44的把持面(表面)44a上形成有多个缝合器变形槽192。各个缝合器变形槽192为了能够使缝合器180的一对腿部180a(参照图10C)分别向内侧弯折变形而将底面形成为例如大致圆弧状。因而，配置于第1钳构件42的能量输出部44的表面也具有作为缝合器180的砧座的功能。
图10A所示的引导槽184和图10B所示的缝合器变形槽192分别形成在相对的位置。
另外，在本实施方式中，第1实施方式中说明的驱动杆82为了使推杆182移动而发挥作用。另外，在该实施方式中，优选的是，第1量输出部44及第2能量输出部54使用加热器等。
简单地说明该实施方式的治疗处理系统10的作用。对于第1实施方式中说明的内容，适当地省略记载。
若使开闭杆72的操作部76接近手柄主体20a的另一端22b，则如图5B所示，连动体112的嵌合部116嵌合于手柄主体20a的嵌合座部102。此时，限制了开闭杆72向第2方向β转动。
当开闭杆72向第1方向α转动后，外筒34相对于内筒32前进，第2把持部26b相对于第1把持部26a闭合。因此，能够利用能量输出部44、54的把持面44a、54a把持生物体组织。即，当使开闭杆72向第1方向α转动后，第1末端执行器26进行动作。因此，能够利用能量输出部44、54的把持面44a、54a把持生物体组织。若在该状态下按压脚踏开关16的踏板16a，则利用热能对能量输出部44、54之间的生物体组织进行处理。
在这种处理之后，使驱动杆82向第1方向γ转动而接近开闭杆72，解除连动体112的嵌合部116嵌合于手柄主体20a的嵌合座部102的状态。而且，驱动杆82的一对抵接面88抵接于开闭杆72。
若使驱动杆82向第1方向γ转动，则推杆182前进。即，当驱动杆82向第1方向γ转动后，第2末端执行器28进行动作。因此，在经由引导槽184利用缝合器180的一对腿部180a刚贯穿了生物体组织之后，能够在用缝合器变形槽192内使缝合器180的一对腿部180a以彼此相对的方式向使用热能处理后的生物体组织折入而将缝合器180固定于生物体组织。
然后，若使开闭杆72向第2方向β转动，则抵接于开闭杆72的驱动杆82也向第2方向δ转动。而且，与开闭杆72连动的连动体112的嵌合部116相对于手柄主体20a的嵌合座部102远离。
因而，能够打开第1把持部26a及第2把持部26b，并且将盒178内的推杆182拉入轴24的内侧。
至此，参照附图具体说明了几个实施方式，但是本发明并不限定于上述实施方式，包括在不脱离其主旨的范围内进行的所有实施。
