Translated fromChinese技术领域technical field
本发明涉及医疗器械领域，进一步涉及电动吻合器，特别涉及用于电动吻合器的击发与弯转切换装置及其电动吻合器。The invention relates to the field of medical instruments, further relates to an electric stapler, in particular to a firing and turning switching device for the electric stapler and the electric stapler thereof.
背景技术Background technique
切割吻合器包括操作手柄、轴组件和末端执行器，其中末端执行器用于在操作手柄的控制下对人体内腔的组织进行切割缝合。现有电动腔镜切割吻合器和手动切割吻合器的末端执行器的弯转大多是通过手动旋转旋钮来实现的，在操作过程中，临床医生需要用一只手操作切割吻合器的柄部，用另一只手通过旋转旋钮来控制末端执行器的弯转。The cutting and stapler includes an operating handle, a shaft assembly and an end effector, wherein the end effector is used for cutting and suturing the tissue in the human body cavity under the control of the operating handle. The bending of the end effector of the existing electric endoscopic cutting stapler and manual cutting stapler is mostly realized by manually rotating the knob. During the operation, the clinician needs to operate the handle of the cutting stapler with one hand. Use the other hand to control the end effector bend by turning the knob.
这种技术的缺陷在于无法实现单手操作，且通过旋转旋钮操作时比较费力增加了临床医生的疲劳强度，同时只能实现固定的弯转角度。The disadvantage of this technology is that it cannot be operated with one hand, and it is laborious to operate by rotating the knob, which increases the fatigue strength of the clinician, and can only achieve a fixed bending angle.
在电动吻合器的操作过程中，如果在不正确的使用环境下触碰电动吻合器的操作开关如在钳口闭合的情况下，触碰电动弯转开关，会使器械钳口偏转，对人体组织造成创伤，造成医疗事故。而在钳口打开的情况下，如果勿触碰电动击发开关，会使器械产生损坏。因此设计一种电动击发与电动弯转的切换装置，在错误操作电动吻合器的电动击发和电动弯转开关时，避免电动击发和电动弯转系统执行动作错误则显得尤为重要。During the operation of the electric stapler, if the operation switch of the electric stapler is touched in an incorrect use environment, such as touching the electric bending switch when the jaws are closed, the jaws of the instrument will be deflected, which is harmful to the human body. Tissue causes trauma, causing medical malpractice. With the jaws open, if you do not touch the electric firing switch, it will cause damage to the instrument. Therefore, it is particularly important to design a switching device for electric firing and electric bending, when the electric firing and electric bending switches of the electric stapler are operated incorrectly, and it is particularly important to avoid the wrong execution of the electric firing and electric bending system.

示例性方法Exemplary method
具体工作原理如下：The specific working principle is as follows:
电动击发与电动弯转切换装置包括电动击发系统、电动弯转系统、手柄、钳口打开扳钮、切换电路和电源，其中切换电路包括电路切换开关，手柄存在闭合和打开两种状态。The electric firing and electric turning switching device includes an electric firing system, an electric turning system, a handle, a jaw opening toggle, a switching circuit and a power supply, wherein the switching circuit includes a circuit switching switch, and the handle has two states of closed and open.
当手柄处于打开状态时，前端钳口打开，此时钳口打开扳钮在手柄作用下处于不触发电动切换开关的位置，电路切换开关处于断开状态，切换电路此时控制电源只向电动弯转系统进行供电，断开电动击发系统的供电，此时操作电动击发开关，电动击发系统不执行动作，避免了在钳口打开状态时，电动击发系统中切割刀的移动。When the handle is in the open state, the front jaw is opened. At this time, the jaw opening toggle is in a position that does not trigger the electric switch under the action of the handle, and the circuit switch is in the off state. Turn the system for power supply and disconnect the power supply of the electric firing system. At this time, the electric firing switch is operated, and the electric firing system does not perform any action, which avoids the movement of the cutting knife in the electric firing system when the jaws are open.
当手柄处于闭合状态时，前端钳口闭合，此时钳口打开扳钮在手柄作用下处于触发电动切换开关的位置，使电路切换开关处于闭合状态，切换电路此时控制电源断开向电动弯转系统的供电，只对电动击发系统进行供电，此时操作电动弯转开关，电动弯转系统不执行动作，避免了前端钳口闭合组织后，误触发电动弯转开关，而造成钳口左右弯转对组织的损伤。When the handle is in the closed state, the front jaw is closed. At this time, the jaw opening toggle is in the position to trigger the electric switch under the action of the handle, so that the circuit switch is in a closed state, and the switch circuit controls the power supply to disconnect to the electric bend. The power supply of the turning system only supplies power to the electric firing system. At this time, the electric turning switch is operated, and the electric turning system does not perform any action, which avoids the accidental triggering of the electric turning switch after the front jaws close the tissue, causing the jaws to be left and right. Tissue damage from bending.
当手柄处于打开状态时，钳口打开扳钮在手柄作用下处于触发电动切换开关的位置，使电路切换开关处于闭合状态，切换电路此时控制电源只向电动弯转系统进行供电，断开电动击发系统的供电。When the handle is in the open state, the jaw opening toggle is in the position to trigger the electric switch under the action of the handle, so that the circuit switch is in a closed state. Power supply to the firing system.
当手柄处于闭合状态时，钳口打开扳钮在手柄作用下处于不触发电动切换开关的位置，使电路切换开关处于断开状态，切换电路此时控制电源断开向电动弯转系统的供电，只对电动击发系统进行供电。When the handle is in the closed state, the jaw opening button is in a position that does not trigger the electric switch under the action of the handle, so that the circuit switch is in an open state, and the switch circuit controls the power supply to disconnect the power supply to the electric steering system at this time. Only power the electric firing system.
