[0041] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0042] In order to be able to control the automatic forward movement of the firing rack, which helps to improve the working efficiency of the endoscope anastomat, the embodiment provides an endoscope anastomat, which is described below in combination with Figures 1 to 9 The specific content of the embodiment is described in detail.

[0043] The endoscope anastomat in the embodiment comprises a mounting body 1, a firing rack 2, a motor 3, a trigger 5, a hand pushing piece 6, an elastic piece 7 and a circuit board 4 with a trigger switch 401, the motor 3 and the circuit board 4 are both arranged on the mounting body 1 and electrically connected with each other, the firing rack 2 is arranged in the mounting body 1 and in transmission connection with the motor 3, and the mounting body 1 is provided with a first mounting shaft 101 and a second mounting shaft 102. The trigger 5 is in rotational connection with the first mounting shaft 101, and the trigger 5 comprises a first arc-shaped wall 501 and a second arc-shaped wall 502 connected with each other, and the outer wall surface of the first arc-shaped wall 501 can abut against or separate from the trigger switch 401. The hand pushing piece 6 is in rotational connection with the second mounting shaft 102, and the hand pushing piece 6 is provided with a push rod 601, and the push rod 601 abuts against the outer wall surface of the second arc-shaped wall 502. The two ends of the elastic piece 7 are connected with the hand pushing piece 6 and the mounting body 1 respectively, and the elastic piece 7 is used to make the hand pushing piece 6 always have a tendency to push the trigger 5 to abut against the trigger switch 401.

[0044] In summary, the laparoscopic anastomosis device provided by this invention assembles a motor 3 and a circuit board 4 onto a mounting body 1. Pressing the trigger switch 401 on the circuit board 4 causes the motor 3 to rotate, thereby pushing the firing rack 2 forward for firing the staple cartridge assembly. A trigger 5 is assembled onto the first mounting shaft 101 of the mounting body 1, and a pusher 6 is assembled onto the second mounting shaft 102 of the mounting body 1. When the pusher 6 is not subjected to external force, the lever 601 of the pusher 6 abuts against the outer wall of the second arc-shaped wall 502 of the trigger 5 under the action of the elastic member 7, causing the trigger 5 to rotate to the position abutting against the trigger switch 401, and the motor 3 starts working. When the pusher 6 is subjected to external force, the elastic member 7 is compressed and shortened, the lever 601 of the pusher 6 separates from the second arc-shaped wall 502 of the trigger 5, the trigger 5 rotates in the opposite direction under its own gravity, the trigger 5 separates from the trigger switch 401, and the motor 3 stops working. The linkage between the pusher 6 and the elastic element 7 enables the trigger 5 to trigger the trigger switch 401 on the circuit board 4, causing the firing rack 2 to move forward automatically, thus improving the working efficiency of the endoscopic stapler.

[0045] Furthermore, the elastic element 7 is a helical spring, the pusher 6 is provided with a first limiting post 602, and the mounting body 1 is provided with a second limiting post 103. One end of the elastic element 7 is sleeved on the first limiting post 602, and the other end of the elastic element 7 is sleeved on the second limiting post 103. By sleeved on the first limiting post 602 and the second limiting post 103 respectively, the installation position of the elastic element 7 is limited.

[0046] Furthermore, the outer wall surface of the first limiting post 602 is circumferentially provided with a plurality of first limiting protrusions 6021, which are inserted into the inner ring of the elastic member 7, and / or the outer wall surface of the second limiting post 103 is circumferentially provided with a plurality of second limiting protrusions (not shown in the figure), which are inserted into the inner ring of the second elastic member 7. The plurality of first limiting protrusions 6021 circumferentially spaced on the outer wall of the first limiting post 602 are used to increase the insertion force between the first limiting post 602 and the inner ring of the elastic member 7. Similarly, the plurality of second limiting protrusions circumferentially spaced on the outer wall of the second limiting post 103 are used to increase the insertion force between the second limiting post 103 and the inner ring of the elastic member 7, which helps to improve the assembly firmness of the elastic member 7.

[0047] Furthermore, push ears 603 are provided on both sides of the pusher 6. By adding push ears 603, it is convenient for a person to hold the pusher 6 and push the ears 603 forward, so that the pusher 6 rotates in the opposite direction.

[0048] Furthermore, a reinforcing rib 604 is provided between the push lug 603 and the pusher 6. By adding the reinforcing rib 604, the overall structural strength of the pusher 6 can be improved.

[0049] Further, the surface of the push ear part 603 is provided with an anti-skid structure. The anti-skid structure in this embodiment can be, but is not limited to, an anti-skid protrusion, an anti-skid groove, or an anti-skid pattern, which is not limited here.

[0050] Further, a plurality of first connecting holes 402 are arranged on the circuit board 4, and a plurality of second connecting holes 104 are arranged on the mounting body 1. The fasteners pass through the first connecting holes 402 and the second connecting holes 104 to connect them, thereby ensuring the mounting stability of the circuit board 4 on the mounting body 1. The fasteners can be, but are not limited to, bolts or screws.

[0051] Further, a plurality of positioning columns 105 are arranged on the mounting body 1, and a plurality of positioning holes 403 are arranged on the circuit board 4. The positioning columns 105 are inserted into the positioning holes 403. By adding the positioning columns 105 and the positioning holes 403, the mounting precision of the circuit board 4 on the mounting body 1 can be improved.

[0052] Further, a limiting arm 605 is arranged on the hand pushing part 6, and a third mounting column 106 is arranged on the mounting body 1. The handle 8 further comprises an arc-shaped blocking arm 801. The handle 8 is rotationally connected to the third mounting column 106, and the limiting arm 605 is stopped by the arc-shaped blocking arm 801. Figure 1 When the handle 8 is in an open state, the hand pushing part 6 is rotated under the action of the elastic part 7, as shown in FIG. 8B. Because the arc-shaped blocking arm 801 clamps the limiting arm 605, the lever 601 of the hand pushing part 6 cannot push the trigger part 5 to rotate counterclockwise. The trigger part 5 does not contact the trigger switch 401 of the circuit board 4, as shown in FIG. 8C. In this state, the motor 3 is in a power-off state and cannot be fired. Figure 8 When the handle 8 is in a clamping state, as shown in FIG. 8D, the arc-shaped blocking arm 801 does not clamp the limiting arm 605 of the hand pushing part 6. The hand pushing part 6 rotates and pushes the trigger part 5. The first arc-shaped wall 501 of the trigger part 5 presses the trigger switch 401, as shown in FIG. 8E. In this state, the motor 3 is in a power-on state and can be fired. Figure 2 When the handle 8 is in a clamping state, as shown in FIG. 8D, the arc-shaped blocking arm 801 does not clamp the limiting arm 605 of the hand pushing part 6. The hand pushing part 6 rotates and pushes the trigger part 5. The first arc-shaped wall 501 of the trigger part 5 presses the trigger switch 401, as shown in FIG. 8E. In this state, the motor 3 is in a power-on state and can be fired. Figure 9 When the handle 8 is in a clamping state, as shown in FIG. 8D, the arc-shaped blocking arm 801 does not clamp the limiting arm 605 of the hand pushing part 6. The hand pushing part 6 rotates and pushes the trigger part 5. The first arc-shaped wall 501 of the trigger part 5 presses the trigger switch 401, as shown in FIG. 8E. In this state, the motor 3 is in a power-on state and can be fired.

[0053] Further, the arc-shaped blocking arm 801 is provided with a weight-reducing hole 8011. By adding the weight-reducing hole 8011, the weight of the arc-shaped blocking arm 801 can be reduced.
