As shown in fig. 1, the present embodiment includes a stapler body 1, a push rod assembly and a magazine assembly 6, the stapler body 1 includes a clamping portion and a working portion, and when in operation, the clamping portion is held by hand, the working portion is extended into tissue, the magazine assembly 6 is provided at the end of the working portion, and staples are pushed out for stapling. The push rod assembly in the anastomat body 1 is used for pushing the anastomat in the nail box assembly 6 to stitch, the bottom of the clamping part is fixedly connected with a handle 11 and a handle 12, the handle 11 is used for holding, in this example, a handle 12 is arranged, and the handle 12 is used for pressing to realize the closing of a nail seat and a cover plate in the nail box assembly 6.

As shown in fig. 3, the push rod assembly includes a push rod body 21 and a first gear 22 disposed on the push rod body 21, at least part of the push rod body 21 is provided with a spiral structure 27, the first gear 22 is sleeved outside the spiral structure 27, a thread matched with the spiral structure 27 is disposed in an inner cavity of the first gear 22, a second gear 23 meshed with the first gear 22 is disposed below the first gear 22, the second gear 23 is sleeved on a rotating rod 26 and linked with the rotating rod 26, a knob 3 is disposed at the other end of the rotating rod 26, when the knob 3 is screwed, the rotating rod 26 rotates to drive the second gear 23 to rotate, when the second gear 23 rotates, the first gear 22 meshed with the second gear rotates, due to cooperation between the spiral structure 27 and the thread, the first gear 22 drives the push rod to advance, and when the push rod advances, the staples in the staple cartridge assembly 6 are pushed to stitch, so as to achieve the purpose of anastomosis.

The knob 3 is arranged at the top of the clamping part, the knob 3 is provided with a protrusion 31 with symmetrical structure, and a plurality of anti-skid grooves 32 are annularly distributed on the outer peripheral surface. The protruding 31 has a force-borrowing mechanism before rotation, and can realize rapid rotation by pressing the protruding 31, so that the anti-slip groove 32 is used for preventing slipping in the rotation process, and the phenomenon of suture blocking caused by the problem of rotation blocking is avoided. The knob 3 is arranged so that the rotation is continuously performed, and the push rod body 21 is continuously pushed.

The first shaft sleeve 24 and the second shaft sleeve 25 are respectively arranged on two sides of the first gear 22 and the second gear 23, the first shaft sleeve 24 and the second shaft sleeve 25 are respectively clung to two sides of the first gear 22 and the second gear 23 and are of an integral structure, the purpose of the shaft sleeve is to improve the contact area between the first gear 22 and the second gear 23 and the push rod body 21 and the rotating rod 26 respectively, so that the first gear 22 and the second gear 23 are better linked, threads are also arranged in the inner ring of the first shaft sleeve 24, and the first shaft sleeve is also matched with the spiral structure 27.

As shown in fig. 2, fig. 4 and fig. 5, a limiting frame is further disposed above the first gear 22, the limiting frame includes a left bracket 41, a right bracket 42 and a transverse connection plate 43, two ends of the transverse connection plate 43 are respectively connected to the left bracket 41 and the right bracket 42 and located above the first gear 22, the left bracket 41 and the right bracket 42 are respectively located at two ends of the first gear 22 and the second gear 23, one ends of the left bracket 41 and the right bracket 42 are respectively connected to the same rotating shaft 44, the limiting frame can rotate around the rotating shaft 44, a hook 45 is disposed on the rotating shaft 44, a linkage rod 47 is further disposed between the hook 45 and the limiting frame, the hook 45 extends to the lower end of the spiral structure 27 and abuts against the spiral structure 27 in a normal state of the limiting frame, so that even if the push rod is in a locked state, the push rod does not advance, and when only the other end of the limiting frame rotates to enable the push rod to move anticlockwise around the rotating shaft 44, the hook 45 is driven to rotate anticlockwise through the linkage rod 47, so that the hook 45 leaves the spiral structure 27, and unlocking of the push rod body 21 is achieved.

The bottom of one end of the left bracket 41 is provided with a limiting block 46, one side of the limiting block 46 is provided with a rotatable limiting plate 5, the limiting block 46 is located in a moving path of the limiting plate 5, one end of the limiting plate 5 away from the limiting block 46 is rotationally connected inside the anastomat body 1, and the limiting plate 5 is limited to rotate clockwise only in a certain range, so that when the limiting plate 5 rotates, one end, close to the limiting block 46, pushes the limiting block 46 and the left bracket 41 downwards, and accordingly the whole limiting frame is driven to rotate anticlockwise, and the clamping hooks 45 leave the spiral structures 27. At the time of resetting, the left bracket 41 is upward

The terminal surface that stopper 46 is close to limiting plate 5 is first arcwall face, and the terminal surface that limiting plate 5 is close to stopper 46 is also the second arcwall face, and first arcwall face and second arcwall face are evagination arcwall face and indent looks arcwall face respectively, and when the first arcwall face of limiting plate 5 moved clockwise, can contradict each other with the second arcwall face of stopper 46, and the setting of arcwall face makes the conflict more smooth and easy, can not scratch each other.

The one end of left socle 41 still is provided with extension board 48, and extension board 48 one end extends to the back of limiting plate 5, and the back of limiting plate 5 is provided with the recess, and the tip of extension board 48 extends to in the recess, like this when limiting plate 5 moves down, can make the tip of extension board 48 inconsistent with recess top inner wall, like this can drive extension board 48 and spacing frame downward movement equally, realizes the departure of trip 45. The arrangement of the extension rod realizes double control, and ensures that the limiting plate 5 can drive the limiting frame to rotate anticlockwise when rotating clockwise.

The button 51 is arranged at the center of the limiting plate 5, the button 51 extends out of the shell 13 of the anastomat body 1, the through hole 131 is arranged on the shell 13, the button 51 extends into the through hole 131, under the normal state, the button 51 is positioned at the uppermost end of the through hole 131, so that the button 51 can only be downwards moved, the limiting plate 5 can be rotated clockwise when the button 51 is moved downwards, the positioning structure is arranged at the bottom end of the limiting plate 5, when the button 51 is pulled to the lowest end, the fixing structure of the limiting plate 5 is connected with the connecting piece in the anastomat body 1, the temporary fixing of the limiting plate 5 is realized, the smooth unlocking of the spiral structure 27 is ensured, when the button 51 is pulled upwards, the fixing structure is separated from the connecting piece (the fixing structure and the elastic piece are not the description focus of the example and are the existing structures, and are not repeated here.) the limiting plate 5 is reset, the limiting frame and the hook 45 is reset, and the dragging rod body is continuously locked.

When the push rod is specifically used, a working part extends into tissues, then the button 51 is pressed, so that the push rod body 21 is unlocked, then the rotary knob 3 is pushed to advance the push rod body 21, then the stapling nail is pushed to act, after the stapling nail is completed, the knob 3 is reversed to reset the push rod body 21, and then the button 51 is pushed up, so that the push rod body 21 is locked.

The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the present invention and to implement the same, but are not intended to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
