Description

具有开关锁止联动机构的吻合器
本申请要求于2022年11月21日提交到国家知识产权局、申请号为202211452209.2、发明名称为“具有开关锁止联动机构的吻合器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及电动吻合器技术领域，具体地涉及一种具有开关锁止联动机构的吻合器。
背景技术
在微创手术治疗中，电动吻合器常被用于完成组织的切割闭合功能。腔镜吻合器是通过钉仓组件夹持在病灶部位，进行切除，切除的同时将病灶进行缝合的医疗器械。
如公开号为CN107714122A的专利申请所揭示的，现有的电动腔镜切割吻合器和手动切割吻合器的末端执行器的旋转大多是通过手动旋转旋钮来实现的，在实际操作过程中，医生常需要手动旋转吻合器钉匣组件确定合适位置靠近切割组织，在切割与闭合组织过程中要求吻合器切割组件位置相对固定，以减少切割与闭合组织过程中头端位置的拉拽。由于手动控制的精准性有限，尤其在长时间手术中手部产生疲劳，影响对旋钮控制的精准度，从而进一步影响吻合器的末端执行器中切割组件的位置精准度，使得切割组件的位置发生偏移，影响吻合口的成钉效果，导致产生成钉不全或过度挤压等问题，进而导致吻合口的潜在渗漏和不规则狭窄，这样会极大影响手术效果，并不利于病人的术后恢复。
因此，如何提高吻合器的使用稳定性和便捷性是目前急需解决的问题。
发明内容
本发明的目的是克服现有技术存在的不足，提供一种具有开关锁止联动机构的吻合器。
本发明的目的通过以下技术方案来实现：
具有开关锁止联动机构的吻合器，包括壳体、设置于壳体前端的旋钮、以及由旋钮驱动的至少具有可轴向自转的执行件、设置在壳体内的驱动执行件完成吻合的驱动电机、丝杆、穿设于壳体上且其至少有一端外凸于壳体的击发锁定推钮，击发锁定推钮触发击发开关给驱动电机提供电信号，击发锁定推钮的前端具有一驱动部，驱动部的底部固设有与击发开关的检测模块相匹配的触发块，壳体内置有一与丝杆平行设置的推杆，推杆具有第一端和第二端，第一端始终与驱动部抵接，击发锁定推钮通过径向移动来带动驱动部同步驱动推杆相对旋钮做轴向移动，进而使推杆的第二端插入旋钮内锁止旋钮；与此同时，触发块离开检测模块的光路以触发击发开关。
在一些实施例中，驱动部的前端面中心处形成有内凹的过度槽，过度槽的槽底为第一台阶面，驱动部的前端面相对过度槽对称分布形成第二台阶面，第一台阶面、第二台阶面和推杆的第一端的端面均为平面，在初始状态下，推杆的第一端与第一台阶面抵接，其第二端与旋钮分离；在第二状态下，推杆的第一端与第二台阶面抵接，其第二端与旋钮插接。
在一些实施例中，过度槽的槽壁与第一端的端面为相匹配的斜面或弧面。
在一些实施例中，第二端具有一外凸的卡块，旋钮的内侧壁均布有一组与卡块相匹配的 卡槽。
在一些实施例中，推杆上固设有一固定块，且推杆上套设有一弹簧，弹簧的两端分别与固定块、壳体抵接，以通过其弹力来推动推杆的第一端始终与驱动部垂直抵接。
在一些实施例中，击发锁定推钮的上方设置有一可旋转的复位键，击发锁定推钮的顶部具有与复位键相匹配的卡口，复位键为杆状，其末端通过旋转与卡口的内壁抵接并驱动击发锁定推钮复位。
在一些实施例中，复位键包括用于枢转连接的连接座和相对连接座上下两侧设置的第一杆部和第二杆部，第一杆部的宽度大于第二杆部，第二杆部的末端与卡口抵接。
在一些实施例中，卡口的前后端均形成有开口，且其后端开口直径逐渐向其前端开口缩小，形成V字形；第二杆部的末端可穿过前端开口。
在一些实施例中，丝杆上设置有一沿其移动的螺母，螺母的侧壁上设置有一凸块，第一杆部位于凸块的移动轨迹上，使得螺母可通过前移使得凸块驱动复位键顺时针旋转来与卡口分离，螺母可通过后移使得凸块驱动复位键逆时针旋转以与卡口的内壁抵接。
在一些实施例中，检测模块为击发开关探测器、位移传感器、压力探测器中的一种。
本发明的有益效果主要体现在：
1、设置击发锁定推钮和推杆、检测模块之间形成联动结构，使得通过击发锁定推钮的径向移动同时完成对检测模块的触发和对旋钮的锁止，通过锁止旋钮来限定由旋钮控制的切割组件的位置，使得驱动机构在可击发状态下时，切割组件的位置相对固定，保证吻合过程中的使用稳定性，避免旋钮发生转动影响执行的吻合效果，使用机械结构替代手动控制，提高了吻合器的使用便捷性；
2、设置由螺母驱动旋转的复位键，使得在使用完成后，螺母回退的同时驱动复位键驱动击发锁定推钮同步复位，无需手动控制击发锁定推钮的复位，方便快捷，提高使用的流畅性和连贯性，节约医生的操作时间，提高吻合器的操作效率；
3、击发锁定推钮的两端均外凸于壳体，且驱动部、卡口均为对称结构，使得击发锁定推钮可以从任意一侧进行径向移动，来进行对旋钮的锁止或解锁、对击发开关的开闭，同时满足左、右撇子的操作习惯，进一步提高使用便捷性。

如图1至图9所示，本发明揭示了一种具有开关锁止联动机构的吻合器，包括壳体1、设置于壳体1前端的旋钮2、以及由旋钮2驱动的至少具有可轴向自转的执行件、设置在壳体1内的驱动执行件完成吻合的驱动电机、丝杆7、穿设于壳体1上且其至少有一端外凸于壳体1的击发锁定推钮3，击发锁定推钮3触发击发开关给驱动电机提供电信号，击发锁定推钮3的前端具有一驱动部301，驱动部301的底部固设有与击发开关的检测模块6相匹配的触发块302，壳体1内置有一与丝杆7平行设置的推杆4，推杆4具有第一端401和第二端402，第一端401始终与驱动部301抵接，击发锁定推钮3通过径向移动来带动驱动部301同步驱动推杆4相对旋钮2做轴向移动，进而使推杆4的第二端402插入旋钮2内锁止旋钮2；与此同时，触发块302离开检测模块6的光路以触发击发开关。
在一些可行实施例中，检测模块6可以为击发开关探测器、位移传感器、压力探测器中的一种。在其他可行的实施例中，检测模块6可为任意可以检测到触发块302位移的检测模块，检测模块6来通过检测触发块302的位移给击发开关发出击发信号或关闭信号。
本发明中将击发锁定推钮3和推杆4、击发开关的检测模块6之间形成联动结构，使得通过击发锁定推钮3的径向移动同时完成对击发开关的触发和对旋钮2的锁止，使得驱动机构在可击发状态下时，旋钮2保持锁止状态，避免旋钮2在击发时发生转动影响执行件的吻合效果，保证手术效果；另一方面使得旋钮2无需保持手动控制，解放医生的手，缓解医生的手部疲劳，使得医生可以双手交替握持，来提高使用便捷性和稳定性。
具体的如图2-图4所示，驱动部301为固设于击发锁定推钮3前端的凸部，驱动部301的前端面中心处形成有内凹的过度槽303，过度槽303的槽底为第一台阶面，驱动部301的前端面相对过度槽303对称分布形成第二台阶面，第一台阶面、第二台阶面和推杆4的第一端401的端面均为平面，在初始状态下，推杆4的第一端401与第一台阶面抵接，其第二端402与旋钮2分离；在第二状态下，推杆4的第一端401与第二台阶面抵接，其第二端402与旋钮2插接。
在一些可行实施例中，驱动部301可以与击发锁定推钮3一体成型，在其他可行的实施例，驱动部301也可以是其他具有间距的抵接面的驱动结构，例如连续的波浪状、齿状等，此处不做限定。第一台阶面、第二台阶面和推杆4的第一端401的端面作为抵接面，均为平面的结构可以增大第一端401与第一台阶面、第二台阶面之间抵接的面积，来便于达到抵接的目的，并在抵接的过程中减少抵接面的磨损。当然，在其他可行的实施例中，第一端401与第一台阶面、第二台阶面之间的抵接面也可以不是平面。
过度槽303的设置使得驱动部301的前端面形成具有落差的第一台阶面和第二台阶面，进而驱动推杆4进行移动。过度槽303的槽壁用于第一台阶面和第二台阶面之间的流畅过度，过度槽303的槽壁与第一端401的端面为相匹配的斜面或弧面。在一些可行实施例中，过度 槽303的槽壁为倾斜延伸的斜面，并对称形成V字型，过度槽303的侧壁倾斜的结构可以在击发锁定推钮3径向移动时，便于推杆4的第一端401沿过度槽303的侧壁移动至第二台阶面上，来提高推杆4轴向移动的流畅性。进一步的，第一端401的端面两侧形成与过度槽303的侧壁相匹配的斜面，使得第一端401可以更流畅地沿过度槽303移动，在第一台阶面和第二台阶面之间快速切换。在其他可行的实施例中，过度槽303的槽壁可为光滑的弧面，第一端401为与之相匹配的弧形，来使得第一端401可以沿过度槽303移动以对旋钮2起到锁止及复位的作用。
如图5-图8所示，第二端402具有一外凸的卡块403，旋钮2的内侧壁均布有一组与卡块403相匹配的卡槽201。卡块403与卡槽201卡接，使得推杆4对旋钮2起到锁止作用，避免旋钮2在击发状态下旋转来改变执行件的角度，保证手术的稳定性和精准性。
进一步的，推杆4上固设有一固定块405，且推杆4上套设有一弹簧404，弹簧404的两端分别与固定块405、壳体1抵接，以通过其弹力来推动推杆4的第一端401始终与驱动部301垂直抵接。弹簧404具有预缩量来保证其对推杆4施加足够的驱动力来使得推杆4的第一端401与驱动部301保持抵接。在其他可行的实施例中，推杆4也可以通过其他施力机构来驱动其做轴向移动。如图9所示，壳体1的内壁上设置限位块102来与弹簧404的端部抵接，实现与壳体1的间接连接。在其他可行的实施例中，壳体1的内壁上也可以设置其他可与弹簧404的端部抵接或固接的结构，使得弹簧404的另一端与壳体1直接抵接，此处不做限制。
如图2、图3、图4、图5、图7所示，击发锁定推钮3的上方设置有一可旋转的复位键5，击发锁定推钮3的顶部具有与复位键5相匹配的卡口304，复位键5为杆状，其末端通过旋转与卡口304的内壁抵接并驱动击发锁定推钮3复位。
具体的，复位键5包括用于枢转连接的连接座501和相对连接座501上下两侧设置的第一杆部502和第二杆部503，第一杆部502的宽度大于第二杆部503，第二杆部503的末端与卡口304抵接。壳体1内设置有用于连接的连接板101，连接座501与连接板101枢轴连接，使得复位键5可以实现旋转。
卡口304的前后端均形成有开口，且其后端开口直径逐渐向其前端开口缩小，形成V字形；第二杆部503的末端可穿过前端开口。卡口304V字形的结构使得卡口304形成倾斜的内壁，第二杆部503与卡口304的内壁抵接后，第二杆部503的末端随着第二杆部503的旋转可以沿卡口304的内壁移动，来推动卡口304做径向移动。
同时，本发明的一些可行的实施例中，壳体1的两侧均具有使得击发锁定推钮3的端部外凸的通孔，击发锁定推钮3可以从任意一侧按压进行径向移动，卡口304的V字形结构使得卡口304具有对称性，使得击发锁定推钮3从其任意一端做径向移动，卡口304均可以受复位键5的第二杆部503驱动进行反向径向移动，来使得击发锁定推钮3完成复位。同理，驱动部301也为对称结构，使得击发锁定推钮3可以从任意一侧进行径向移动，来切换第一台阶面和第二台阶面，来进行对旋钮的锁止或解锁、对击发开关的开闭，这样的结构可以同时满足左、右撇子的操作习惯，进一步提高使用便捷性。
本方案中的复位键5由驱动机构驱动旋转，具体的如图2、图3、图5、图7所示。丝杆7上设置有一沿其移动的螺母8，驱动电机(图中未示出)驱动丝杆7自转，丝杆7与螺母8螺接并通过自转来驱动螺母8沿其移动，螺母8的侧壁上设置有一凸块801，第一杆部502位于凸块801的移动轨迹上，使得螺母8可通过前移使得凸块801驱动复位键5顺时针旋转 来与卡口304分离；螺母8可通过后移使得凸块801驱动复位键5逆时针旋转以与卡口304的内壁抵接。这样的结构使得在使用完成后，螺母8回退的同时会带动复位键5驱动击发锁定推钮3同步完成复位，无需手动控制击发锁定推钮3进行复位，实现结束击发状态、解锁旋钮2、使驱动电机处于不可启动状态的自动化同步动作，使得吻合器快速恢复初始状态，方便快捷，提高使用的流畅性和连贯性，节约医生的操作时间，提高吻合器的操作效率。
由于第一杆部502的宽度大于第二杆部503，可以增强第一杆部502的强度，在一些可行的实施例中，第一杆部502与凸块801相对的侧部可以为平面，来增大其与凸部801的接触面积，减小凸部801对第一杆部502的冲击，提高复位键5的使用寿命。
此外，执行件包括钳口、钉仓座、抵钉座、转向拉片、刀片、执行套管等用于完成切割、吻合动作的部件，此为现有技术，不是本发明的重点，此处不做赘述。
本方案的工作流程为：
首先，握持壳体1，使执行件前端的钳口移动至待操作部位，并通过旋转旋钮2来调节钳口的角度，使得钳口对准需吻合的待操作部位，此时击发锁定推钮3处于如图2所示的初始状态，推杆4的第一端401与第一台阶面抵接，其第二端402与旋钮2内的卡槽201分离。
然后，径向按压击发锁定推钮3，使得击发锁定推钮3处于如图4所示的第二状态，此时推杆4的第一端401与第二台阶面抵接，其第二端402与旋钮2内的卡槽201插接，以锁止旋钮2，此时触发块302离开检测模块6的光路，以使驱动电机处于可启动状态。
接着，按压击发开关启动驱动电机，驱动电机驱动丝杆7自转，丝杆7的自转驱动螺母8沿其移动，螺母8上固接有一驱动杆(图中未示出)，驱动杆的远端与执行件连接，螺母8带动驱动杆同步轴向移动，以使得驱动杆通过轴向移动控制执行件进行击发吻合(此为现有技术，此处不作赘述)。
最后，执行件击发吻合完成，再次按压击发开关控制驱动电机反转，使得丝杆7反向自转，进而使得螺母8向丝杆7的近端移动，附图3、图5为螺母8向丝杆7近端移动的过程，在此过程中，螺母8的回退会驱动复位键5逆时针旋转，进而使得第二杆部503的末端推动卡口304做径向移动，使得击发锁定推钮3由第二状态恢复至初始状态，推杆4的第一端401由第二台阶面切换至第一台阶面，推杆4的第二端402与旋钮2内的卡槽201分离，以解除对旋钮2的锁止，触发块302再次卡设于检测模块6内以遮挡检测模块6的光路，使得驱动电机处于不可启动状态。
