请参阅图1至图3,本发明第一实施例提供一种超声外科手术装置100。超声外科手术装置100用于对组织进行处理。超声外科手术装置100包括设置于超声外科手术装置100远端的刀尖10及第一夹持臂20。刀尖10和夹持臂可统称为端部执行器。刀尖10包括相对设置的顶面11及底面12、及位于顶面11及底面12之间且相对设置的第一侧面13及第二侧面14。顶面11包括第一咬合面111及第二咬合面112。第一咬合面111与第二咬合面112连接,并在第一咬合面111及第二咬合面112之间形成第一边缘113。第一咬合面111连接第二侧面14。第二咬合面112连接第一侧面13。底面12包括第三咬合面121及第四咬合面122。第三咬合面121与第四咬合面122连接,并在第三咬合面121及第四咬合面122之间形成第二边缘123。第四咬合面122还连接至第一侧面13。第三咬合面121连接至第二侧面14。其中,第二咬合面111在第一边缘处113的切线与第一咬合面111的切线之间形成第一角度a。第三咬合面122在第二边缘123处的切线与第四咬合面121的切线之间形成第二角度b。第一角度a与第二角度b不同。刀尖10与第一夹持臂20可相对转动设置,以使第一夹持臂20可开合地配合顶面11或底面12来对组织进行处理。
需要说明的是,当对组织进行处理(如切割和止血)时,只需要使用顶面11或底面12配合第一夹持臂20配合。其中,第一及第二角度a及b的大小 直接决定顶面11及底面12的切割及止血效果。顶面11可以为钝面。底面12可以为锐面。其中,锐面切割效果要优于钝面的切割效果。但是钝面的止血效果要优于锐面的止血效果。
在本实施例中,刀尖10包括相对设置的顶面11及底面12、及位于顶面11及底面12之间且相对设置的第一侧面13及第二侧面14。顶面11包括第一咬合面111及第二咬合面112。第一咬合面111与第二咬合面112连接,并在第一咬合面111及第二咬合面112之间形成第一边缘113。第一咬合面111连接第二侧面14。第二咬合面112连接第一侧面13。底面12包括第三咬合面121及第四咬合面122。第三咬合面121与第四咬合面122连接,并在第三咬合面121及第四咬合面122之间形成第二边缘123。第四咬合面122还连接至第一侧面13。第三咬合面121连接至第二侧面14。其中,第二咬合面112在第一边缘处113的切线与第一咬合面111的切线之间形成第一角度a。第三咬合面121在第二边缘123处的切线与第四咬合面122的切线之间形成第二角度b。第一角度a与第二角度b不同。刀尖10与第一加持臂20可相对转动设置,以使第一夹持臂20可开合地配合顶面11或底面12来对组织进行处理。因此,本实施例中具有两种切割和止血效果不同的顶面11和底面12,可以满足不同外科手术的不同需求,从而扩大了超声外科手术装置100的使用范围。
第一、第二、第三和第四咬合面111-114可选择性地为曲面或平面。对于本发明的超声外科手术装置而言,曲面构造的咬合面通常具有较佳的切割效果,而平面构造的咬合面则可显著降低刀尖的加工成本。实际应用中,各个咬合面选择为曲面或平面可结合具体设计要求来合理设定。在本实施例中,第一、第三和第四咬合面均为曲面。另外,超声外科手术装置的刀尖包括从其远端延伸到近端的中心轴线。相对于该中心轴线,上述各咬合面可采用内凹曲面或外凸曲面。在非限制性实施例中,内凹曲面通常有利于获得锐面的切割效果,而外凸曲面通常有利于获得钝面的止血效果。
进一步地,刀尖10可转动地设置在超声外科手术装置100的远端,以使顶面11或底面12分别配合第一夹持臂20来对组织进行处理。
具体地,当需要顶面11与第一夹持臂20配合来对组织进行处理时,通过转动刀尖10,使顶面11对应第一夹持臂20即可。同理,当需要底面12与第 一夹持臂20配合来对组织进行处理时,通过转动刀尖10,使底面12对应第一夹持臂20即可。
请继续参阅图4及图1,超声外科手术装置100还包括超声发生器30、手柄40及刀体50。超声发生器30通过导线60连接至手柄40,以输出电信号至手柄40。手柄40可拆卸地连接至刀体50。刀体50包括换能器(未示出)、第一连接杆51、第二连接杆52、旋转件53及扳机54。换能器连接至手柄40,以接收电信号,用于将电信号转换成纵向振动的机械能。第一连接杆51套设在第二连接杆52内。第一连接杆51的第一端作为超声外科手术装置100的远端设置有刀尖10。换能器还连接至第一连接杆51的第二端,以驱动第一连接杆51纵向振动,从而带动刀尖10纵向振动。第二连接杆52的第一端对应第一连接杆51的第一端,且作为超声外科手术装置100的远端设置有第一夹持臂20。扳机54连接第一夹持臂20,以通过触发扳机54来控制第一夹持臂20的开合。旋转件53连接至第一连接杆51的第二端,以通过转动旋转件53来转动第一连接杆51及刀尖10,从而使得顶面11或底面12分别配合第一夹持臂20来对组织进行处理。
在本实施例中,手柄40与刀体50螺纹连接。在其他实施例中,手柄40也可以通过其他方式与刀体50可拆卸连接。
进一步地,刀头50还包括第三连接杆55。第三连接杆55套设于第二连接杆52的外部。扳机54通过第二连接杆52连接至第一夹持臂20。通过触发扳机54来带动第二连接杆52沿第二连接杆52的轴向移动,从而带动第一夹持臂20沿着第二连接杆52的轴向移动来抵顶第三连接杆55,进而改变第一夹持臂20的开合状态。
具体地,当扳机54未被触动时,第一夹持臂20处于张开状态,第一夹持臂20与刀尖10之间具有夹持空间70。当触动扳机54时,扳机54带动第二连接杆52朝向手柄40的方向沿着第二连接杆52的轴向移动,从而带动第一夹持臂20朝向手柄40的方向沿着第二连接杆52的轴向移动。第一夹持臂20会抵顶至第三连接杆55的第一端(第三连接杆55的第一端对应第二连接杆52的第一端)。第一夹持臂20处于向刀尖10闭合状态。第一夹持臂20与刀尖10之间的夹持空间70逐渐减小,直至第一夹持臂20与刀尖10贴合。从而 可以实现对组织进行处理的操作。
进一步地,刀头50还包括壳体56。壳体56包括相对设置的第一侧壁561及第二侧壁562。换能器设置于壳体56内。扳机54设置于第二侧壁562上。第一侧壁561形成有第一通孔,收容手柄40的第一端,使手柄40的第一端可拆卸地与换能器连接。第二侧壁562上设有带有第二通孔(未示出)的固定件563。第一连接杆51的第二端穿过第二通孔连接至换能器。第二连接杆52的第二端穿过第二通孔连接至扳机54。第三连接杆55的第二端穿过第二通孔固定于壳体56内。
请继续参阅图5,本发明第二实施例提供了一种超声外科手术装置200。第二实施例提供的超声外科手术装置200与第一实施例提供的超声外科手术装置100相似,两者的区别在于:在第二实施例中,超声外科手术装置200还包括第二夹持臂210。第一夹持臂20对应顶面11设置,并可开合地与顶面11配合来对组织进行处理。第二夹持臂210对应底面12设置,并可开合地与底面12配合来对组织进行处理。
需要说明的是,在本实施例中,第一夹持臂20对应顶面11,并可开合地与顶面11配合利用第二咬合面112来对组织进行处理。第二夹持臂210对应底面12,并可开合地与底面12配合利用第三咬合面121来对组织进行处理。因此,本实施例中具有两种处理效果(如切割和止血效果)不同的顶面11和底面12,可以满足不同外科手术的不同需求,从而扩大了超声外科手术装置200的使用范围。
当然,当超声外科手术装置200包括第一夹持臂20及第二夹持臂210时,刀尖10与第一夹持臂20可以不相对转动地设置,只需要第一夹持臂20对应顶面11设置,并可开合地与顶面11配合来对组织进行处理。第二夹持臂210对应底面12设置,并可开合地与第底面12配合来对组织进行处理。
其中,第一及第二夹持臂20及210可相对于刀尖10可开合的偏转。第一及第二夹持臂20及210相对于刀尖10可开合的偏转角度范围为0-180度。
需要说明的是,当需要利用超声外科手术装置200对组织进行处理,且根据实际需要选择了顶面11与第一夹持臂20配合时,可以将第二夹持臂210相对刀尖10偏转,使第二夹持臂210相对于刀尖10开合的偏转角度为180度。 即当需要利用第一夹持臂20与顶面11配合时,保持第二夹持臂210与刀尖10基本在同一平面上,从而可以防止第二夹持臂210与刀尖10之间具有锐角或钝角(即第二夹持臂210与刀尖10不再同一平面)而造成在第一夹持臂20与顶面11配合对组织进行处理时给周边组织带来误损伤。
同理,当需要利用超声外科手术装置200对组织进行处理,且根据实际需要选择了底面12与第二夹持臂210配合时,可以将第一夹持臂20相对刀尖10偏转,使第一夹持臂20相对于刀尖10可开合的偏转角度为180度。即当需要利用第二夹持臂210与底面12配合时,保持第一夹持臂20与刀尖10基本在同一平面上,从而可以防止第一夹持臂20与刀尖10之间具有锐角或钝角(即第一夹持臂20与刀尖10不再同一平面)而造成在第二夹持臂210与底面12配合对组织进行处理时给周边组织带来误损伤。
在另一实施方式中,该超声外科手术装置200具有壳体、以及从自壳体开始向远端(远离操作者握持端)延伸的外套管。第一夹持臂20和/或第二夹持臂210设置在外套管远离壳体的远端。其中,第一夹持臂20和/或第二夹持臂210可至少部分地收缩到外套管中,从而降低使用其中一个夹持臂时另一夹持臂对夹持动作的干扰或对周边组织造成的损失,同时缩回其中一个夹持臂也可使手术所需的开口尺寸尽可能减小。例如,在根据需要选择了使用顶面与第一夹持臂20配合时,可将第二夹持臂210缩回到外套管中,从而尽量减少第二夹持臂210可能对周边组织带来误伤。
进一步地,超声外科手术装置200还包括切换器(未示出)。切换器连接至扳机54及第一和第二夹持臂20及210。切换器用于选择性地将扳机54连接至第一夹持臂20或第二夹持臂210。
需要说明的是,当需要第一夹持臂20与顶面11配合来对组织进行处理时,只需启动切换器,使得第一夹持臂20连接至扳机54。通过启动扳机54即可实现第一夹持臂20与顶面11进行夹合。同理,当需要第二夹持臂210与底面12配合来对组织进行处理时,只需启动切换器,使得第二夹持臂210连接至扳机54。通过启动扳机54即可实现第二夹持臂210与底面12进行夹合。因此,本实施例中,第一连接杆51可以无需进行转动。
以上所述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。
