Description

腔镜切割吻合器的切割刀 技术领域
本发明涉及到在腔镜外科手术中使用的腔镜切割吻合器的切割刀,特别涉及到在腹腔镜外科手术中使用的腔镜切割吻合器的切割刀,也特别涉及到在胸腔镜外科手术中使用的腔镜切割吻合器的切割刀,更特别涉及到手动的腔镜切割吻合器的切割刀,也更特别涉及到电动的腔镜切割吻合器的切割刀,还更特别涉及到手术机器人使用的腔镜切割吻合器的切割刀。
背景技术
在腹腔镜外科手术和胸腔镜外科手术中,各种手动的、电动的和手术机器人使用的腔镜切割吻合器通常被用于腹腔中、胸腔中和泌尿生殖系统中的切割和吻合手术,可以减少手术创伤,缩短手术时间,提高手术质量。
美国专利US20180126504A1和US20180310931A1中介绍的各种腔镜切割吻合器,其组成部分包括执行组件、延伸组件和操作组件。延伸组件连接操作组件和执行组件。执行组件中有钉仓组件和钉砧组件。操作组件中有驱动件。驱动件的前部有切割刀。操作组件控制驱动件在执行组件中前后移动。延伸组件上可以有关节组件,也可以没有关节组件。操作组件控制执行组件的动作。各种操作组件既可以是手动的操作组件,也可以是电动的操作组件,还可以是手术机器人的操作组件。
美国专利US20180126504A1的腔镜切割吻合器的切割刀被直接加工在驱动件的驱动头上。美国专利US20180310931A1的腔镜切割吻合器的切割刀被直接加工在驱动件上。上述两种腔镜切割吻合器的第一令人不满意处是,由于驱动件或驱动件的驱动头的形状比较复杂,因此在驱动件上或在驱动件的驱动头上直接加工的切割刀的加工过程复杂,加工成本也较高,刀刃的锋利度难以保证,带有切割刀的驱动件储存较困难。上述两种腔镜切割吻合器的第二令人不满意处是,由于直接加工在驱动件的驱动头上的切割刀或直接加工在驱动件上的切割刀是不可更换的,因此在腔镜切割吻合器使用中,如果发现驱动件上的切割刀被损伤,则要更换另一把腔镜切割吻合器,造成手术费用较高,使用也不方便。
由上述显然可以看出,现在已经设计了不同式样的腔镜切割吻合器的切割刀,并且新的腔镜切割吻合器的切割刀的研制工作仍在继续,以便对每年世界上大量使用的腔镜切割吻合器作进一步的改进,使得加工时更方便和手术费用更低。
发明内容
本发明的第一目的在于提出一种腔镜切割吻合器的切割刀,采用在带有刀刃的长条形的金属薄片的表面上加工有多个凹痕的技术特征;实现在凹痕的两侧弯折带有刀刃的长条形的金属薄片的凹痕,使得带有刀刃的长条形的金属薄片沿凹痕断裂,即可获得所需尺寸和形状的切割刀的技术方案。本发明的腔镜切割吻合器的切割刀达到加工过程简单、方便、快速、刀刃锋利和便于储存的技术效果;达到大幅度降低腔镜切割吻合器的切割刀加工费用的技术效果;达到在生产过程中或腔镜外科手术中依次在各个凹痕的两侧弯折带有刀刃的长条形的金属薄片的凹痕,使得带有刀刃的长条形的金属薄片沿凹痕断裂,即可获得多个所需尺寸和形状的切割刀的技术效果。
本发明的第二目的在于提出一种腔镜切割吻合器的切割刀,采用驱动件的前部有开口的切割刀镶嵌槽的技术特征;实现切割刀插入切割刀镶嵌槽内时,切割刀被安装在驱动件上,此时切割刀的刀刃位于切割刀镶嵌槽的开口处的技术方案;实现在切割刀移出切割刀镶嵌槽内时切割刀即被移出驱动件的技术方案。本发明的腔镜切割吻合器的切割刀达到可以采用与驱动件不同的材料分别制造,使得切割刀和驱动件的加工都更方便,加工质量都更高和加工成本都更低的技术效果。
本发明的第三目的在于提出一种腔镜切割吻合器的切割刀,采用切割刀被安装在驱动件的切割刀镶嵌槽内的技术特征;实现操作组件控制驱动件上的切割刀向前移动,直至切割刀伸出执行件座,将切割刀从切割刀镶嵌槽内取出,即可将切割刀移出驱动件后再安装另一切割刀的技术方案。本发明的腔镜切割吻合器的切割刀达到更换切割刀的过程简单、方便、快速和安全的技术效果,达到降低腔镜外科手术费用和提高手术质量的技术效果。
本发明的目的是通过下述技术方案实现的:
本发明的腔镜切割吻合器包括执行组件、延伸组件和操作组件。延伸组件连接操作组件和执行组件。执行组件中有钉仓组件和钉砧组件。操作组件中有驱动件。操作组件控制驱动件在执行组件中前后移动。延伸组件上可以有关节组件,也可以没有关节组件。操作组件可以是手动的操作组件或电动的操作组件、也可以是手术机器人使用的操作组件。
驱动件的前部有切割刀镶嵌槽和切割刀。切割刀的刀刃既可以位于切割刀的单面,也可以位于切割刀的双面。切割刀的不带刀刃的角上可以有倒角,带刀刃的前下角上也可以有倒角。切割刀上的倒角可以是倒直角,也可以是倒圆角。切割刀镶嵌槽的前部有开口。在切割刀插入切割刀镶嵌槽内后,切割刀被安装在驱动件上;此时切割刀的刀刃位于切割刀镶嵌槽的开口处。在切割刀移出切割刀镶嵌槽内时,切割刀即被移出驱动件。当钉仓组件和钉砧组件处于闭合状态时,切割刀镶嵌槽的开口处位于钉仓组件的组织接触面和钉砧组件的组织接触面之间的缝隙处。
本发明的腔镜切割吻合器的切割刀在使用前为长条形的金属薄片。长条形的金属薄片在长边上有刀刃、在表面上有与刀刃成角度的多个凹痕。凹痕之间可以相互平行,也可以相互不平行。在切割刀被安装在驱动件上的过程中,第一步,在最靠近带有刀刃的长条形的金属薄片的短边的凹痕的两侧弯折带有刀刃的长条形的金属薄片的凹痕,使得带有刀刃 的长条形的金属薄片沿凹痕断裂,即可获得所需尺寸和形状的切割刀;第二步,将切割刀安装在驱动件上。此后,依次在各个凹痕的两侧弯折带有刀刃的长条形的金属薄片的凹痕,即可获得多个切割刀。
带有刀刃的长条形的金属薄片的一端上可以有孔。在凹痕的两侧弯折带有刀刃的长条形的金属薄片的凹痕时,控制孔的位置,可以对带有刀刃的长条形的金属薄片起到移动和约束的作用。
长条形的金属薄片的长边上可以有双面刀刃。在凹痕的两侧弯折带有双面刀刃的长条形的金属薄片的凹痕时,获得带有双面刀刃的切割刀。长条形的金属薄片的长边上也可以有单面刀刃。在凹痕的两侧弯折带有单面刀刃的长条形的金属薄片的凹痕时,获得带有单面刀刃的切割刀。
在带有刀刃的长条形的金属薄片的不带刀刃的凹痕处可以有角形槽。在凹痕的两侧弯折带有刀刃的长条形的金属薄片的凹痕,获得的切割刀在不带刀刃的角上有倒角。
在带有刀刃的长条形的金属薄片的凹痕的两侧可以有角形槽。在凹痕的两侧弯折带有刀刃的长条形的金属薄片的凹痕,获得的切割刀的角上带有倒角。
在带有刀刃的长条形的金属薄片的相邻凹痕之间可以带有孔,使得在凹痕的两侧弯折带有刀刃的长条形的金属薄片的凹痕后,获得的切割刀的中部带有约束缺口。在带有刀刃的长条形的金属薄片的凹痕上也可以带有孔、一端的短边上可以带有凹槽,使得在凹痕的两侧弯折带有刀刃的长条形的金属薄片的凹痕后,获得的切割刀的上部和下部分别带有上约束缺口和下约束缺口。
本发明的腔镜切割吻合器的切割刀镶嵌槽的前部有带有开口的约束边。在切割刀插入切割刀镶嵌槽内时,切割刀镶嵌槽上的约束边阻挡切割刀向前移动。
切割刀镶嵌槽的约束边的两侧可以有交错分布的左约束凸块和右约束凸块。先将切割刀的刀刃插入切割刀镶嵌槽的左约束凸块和右约束凸块内,再将切割刀的刀刃绕约束边转动,使得切割刀转入切割刀镶嵌槽内,即可将切割刀安装在驱动件上;此时,切割刀镶嵌槽上的左约束凸块和右约束凸块将切割刀的刀刃约束在切割刀镶嵌槽内。再将切割刀的刀刃绕约束边转动,使得切割刀移出切割刀镶嵌槽,即可将切割刀移出驱动件。
本发明的腔镜切割吻合器的切割刀镶嵌槽上有约束凸块。切割刀上有约束缺口。当切割刀的约束缺口插在切割刀镶嵌槽的约束凸块上时,切割刀镶嵌槽阻挡切割刀前后移动。当切割刀的约束缺口移出切割刀镶嵌槽的约束凸块时,切割刀即被移出驱动件。
本发明的腔镜切割吻合器的切割刀镶嵌槽贯穿驱动件的左右两侧。当带有双面刀刃的切割刀安装在切割刀镶嵌槽内时,切割刀的刀刃位于切割刀镶嵌槽的左右两侧的中间。
