技术领域Technical Field
本发明涉及吻合器技术领域，尤其涉及一种摆头角度手动复位机构及其电动腔镜吻合器。The present invention relates to the technical field of staplers, and in particular to a manual resetting mechanism for a swing head angle and an electric laparoscopic stapler thereof.
背景技术Background Art
电动腔镜吻合器一般包括器身本体及设置在器身前端的钉仓组件，且两者之间设有摆头以在控制机构的驱动下带动钉仓组件转向从而到达病灶部位并进行切割及缝合，初始进入腹腔时钉仓组件与器身本体为同轴设置，进入腹腔之后为了到达病灶部位，钉仓组件需进行转向，此时钉仓组件与器身本体并非同轴，而当手术结束后需将钉仓组件复位使其与器身本体同轴后方可取出。An electric laparoscopic stapler generally includes a main body of the device and a stapler assembly arranged at the front end of the device body, and a swing head is provided between the two to drive the stapler assembly to turn under the drive of a control mechanism so as to reach the lesion site and perform cutting and suturing. When initially entering the abdominal cavity, the stapler assembly and the main body of the device are coaxially arranged. After entering the abdominal cavity, in order to reach the lesion site, the stapler assembly needs to be turned. At this time, the stapler assembly and the main body of the device are not coaxial. When the operation is completed, the stapler assembly needs to be reset so that it is coaxial with the main body of the device before it can be removed.
现有技术中的电动腔镜吻合器均通过电动控制钉仓组件的转向及复位，其不具备手动复位功能，而电路结构可靠性不高，经常会出现故障，当钉仓组件转向后电动腔镜吻合器出现故障，此时钉仓组件无法复位而难以取出，需要破坏吻合器，强行拉动割刀传动机构来使钉仓组件复位，若割刀传动机构无法拉动则需要另外进行手术来将钉仓组件取出。The electric laparoscopic staplers in the prior art all electrically control the steering and resetting of the staple magazine assembly, and do not have a manual resetting function. The circuit structure is not reliable and often fails. When the electric laparoscopic stapler fails after the staple magazine assembly is turned, the staple magazine assembly cannot be reset and is difficult to remove. The stapler needs to be destroyed and the cutter transmission mechanism needs to be forcibly pulled to reset the staple magazine assembly. If the cutter transmission mechanism cannot be pulled, another operation is required to remove the staple magazine assembly.

复位件5，其为手动驱动且与拉钩组件4后端连接用于带动拉钩组件4前后移动，且拉钩组件4后端连接有驱动杆8，驱动杆8为电动控制，其用于电动控制拉钩组件4前后移动以带动摆头3转向或复位，当驱动杆8的电控结构出现故障而无法将摆头3复位后，手动拉动复位件5向前或向后启动，从而带动拉钩组件4前后移动，拉钩组件4带动摆头3转动复位。The reset member 5 is manually driven and connected to the rear end of the hook assembly 4 to drive the hook assembly 4 to move forward and backward, and the rear end of the hook assembly 4 is connected to a driving rod 8, which is electrically controlled and used to electrically control the hook assembly 4 to move forward and backward to drive the swing head 3 to turn or reset. When the electrical control structure of the driving rod 8 fails and the swing head 3 cannot be reset, the reset member 5 is manually pulled forward or backward to start, thereby driving the hook assembly 4 to move forward and backward, and the hook assembly 4 drives the swing head 3 to rotate and reset.
在一些示例中，所述复位件5外部罩设有罩盖6，所述罩盖6两侧凸出形成有凸出部601，所述器身本体1的主壳体101上开设有供凸出部601滑动插入的插槽1011从而实现罩盖6与主壳体101的滑动连接，当需要手动复位时，滑动罩盖6使其与主壳体101脱离，此时复位件5外露可供手动操作。In some examples, the external cover of the reset member 5 is provided with a cover 6, and protrusions 601 are formed on both sides of the cover 6. A slot 1011 is provided on the main shell 101 of the device body 1 for the protrusion 601 to be slidably inserted, thereby realizing a sliding connection between the cover 6 and the main shell 101. When manual reset is required, the sliding cover 6 is separated from the main shell 101, and the reset member 5 is exposed for manual operation.
在一些示例中，所述拉钩组件4后端弯折形成有卡接部401，所述复位件5开设有供卡接部401卡入的卡接槽501，卡接部401卡入卡接槽501从而实现拉钩组件4与复位件5的固定。In some examples, the rear end of the hook assembly 4 is bent to form a snap-fit portion 401 , and the reset member 5 is provided with a snap-fit groove 501 for the snap-fit portion 401 to be snapped into. The snap-fit portion 401 is snapped into the snap-fit groove 501 to fix the hook assembly 4 and the reset member 5 .
在一些示例中，所述器身本体1包括操控组件及位于操控组件前端的套管组件，所述套管组件包括前套管102与后套管103，所述拉钩组件4包括沿轴向穿设在前套管102内部的前拉钩402与沿轴向穿设在后套管103内部的后拉钩403，且所述前套管102开设有供前拉钩402滑动的前滑槽，后套管103开设有供后拉钩403滑动的后滑槽，所述前拉钩402与后拉钩403相互钩连。In some examples, the device body 1 includes a control component and a sleeve component located at the front end of the control component, the sleeve component includes a front sleeve 102 and a rear sleeve 103, the hook assembly 4 includes a front hook 402 axially arranged inside the front sleeve 102 and a rear hook 403 axially arranged inside the rear sleeve 103, and the front sleeve 102 is provided with a front sliding groove for the front hook 402 to slide, and the rear sleeve 103 is provided with a rear sliding groove for the rear hook 403 to slide, and the front hook 402 and the rear hook 403 are hooked with each other.
在一些示例中，所述罩盖6内侧前端设有用于与主壳体101抵接的前限位部602，后端设有与主壳体101抵接的后限位部603，通过前限位部602与后限位部603可限制罩盖6后移的自由度。In some examples, the front inner front end of the cover 6 is provided with a front limit portion 602 for abutting against the main shell 101, and the rear end is provided with a rear limit portion 603 abutting against the main shell 101. The front limit portion 602 and the rear limit portion 603 can limit the freedom of the cover 6 to move backward.
在一些示例中，所述罩盖6前端设有用于对其限位的限位套7，其旋转固定在所述主壳体101上，通过限位套7可限制罩盖6前移的自由度。In some examples, a limiting sleeve 7 for limiting the position of the cover 6 is provided at the front end thereof, and is rotatably fixed to the main housing 101 . The limiting sleeve 7 can limit the freedom of the cover 6 to move forward.
在一些示例中，所述限位套7的内周壁凸出形成有锁定部701，所述主壳体101外周壁凹陷形成有与锁定部701配合的锁定槽1012与解锁槽1013，所述锁定槽1012与解锁槽1013相邻设置且两者均位于锁定部701的旋转轨迹上，解锁槽1013的前端具有供锁定部701进出的开口1014；首先将限位套7沿轴向套设在主壳体101上，并使锁定部701自开口1014进入解锁槽1013，然后旋转限位套7使锁定部701自解锁槽1013进入锁定槽1012从而将限位套7与主壳体101锁定进而对罩盖6进行限位。In some examples, the inner peripheral wall of the limiting sleeve 7 is protruded to form a locking portion 701, and the outer peripheral wall of the main shell 101 is recessed to form a locking groove 1012 and an unlocking groove 1013 that cooperate with the locking portion 701. The locking groove 1012 and the unlocking groove 1013 are arranged adjacent to each other and both are located on the rotation trajectory of the locking portion 701. The front end of the unlocking groove 1013 has an opening 1014 for the locking portion 701 to enter and exit; first, the limiting sleeve 7 is axially sleeved on the main shell 101, and the locking portion 701 enters the unlocking groove 1013 from the opening 1014, and then the limiting sleeve 7 is rotated to make the locking portion 701 enter the locking groove 1012 from the unlocking groove 1013, thereby locking the limiting sleeve 7 and the main shell 101 and limiting the cover 6.
在一些示例中，所述限位套7的外周壁凸出设置有手柄702，通过手柄702可便于对限位套7进行旋转、移动等操作。In some examples, a handle 702 is protruding from the outer wall of the limiting sleeve 7 , and the handle 702 can be used to facilitate operations such as rotating and moving the limiting sleeve 7 .
