[0039] Reference Figures 1 to 8As shown, a stapler beak device according to an embodiment of the utility model comprises: a beak body 100, an anvil seat 200, a movable pin 300, and an elastic member 400. The material of the beak body 100 is a flexible material such as plastic or rubber. The front end of the beak body 100 is narrowed and arranged in an arc shape. A mounting cavity 110 is provided at the rear end of the beak body 100, and a mounting hole 120 extending in the left and right directions is provided on the beak body 100. The front end of the anvil seat 200 is embedded in the mounting cavity 110, and a hollow guide groove 210 is provided inside the anvil seat 200. A cover plate for closing the hollow guide groove 210 is connected to the lower end of the anvil seat 200. The anvil seat 200 is slidably connected to a blade 201, and the blade 201 is used to cut the tissue above the anvil seat 200. The specific structure of the hollow guide groove 210 and the blade 201 is prior art, so it will not be described in detail. The blade 201 can move along the hollow guide groove 210. A guide block is provided at the lower end of the blade 201. The size of the guide block matches the size of the hollow guide groove 210, and the guide block can slide in the hollow guide groove 210. A guide hole 220 extending in the left-right direction is provided on the side wall of the anvil seat 200. The guide hole 220 is connected to the hollow guide groove 210. The movable pin 300 is penetrated in the guide hole 220 and can move along the guide hole 220. The length of the movable pin 300 is greater than the length of the guide hole 220. The movable pin 300 has a first position extending out of the guide hole 220 and inserted into the mounting hole 120. When the movable pin 300 is in the first position, it is inserted into the mounting hole 120 to fix the hawk's beak in the front-to-back direction. The movable pin 300 has a second position retracted in the guide hole 220. When the movable pin 300 is in the second position, it does not extend out of the outer side wall of the anvil seat 200, and the fixation of the hawk's beak body 100 is cancelled. The elastic member 400 is arranged at the front end of the hollow guide groove 210, and the elastic member 400 is connected to the movable pin 300. The elastic member 400 is used to drive the movable pin 300 to remain in the first position. When the blade 201 moves to the front end of the stroke along the hollow guide groove 210, it can push the elastic member 400 to deform, and the elastic member 400 drives the movable pin 300 to move to the second position.

[0040] Reference Figures 1 to 8As shown, it can be understood that the inner wall of the installation cavity 110 is provided with a boss 500, and the boss 500 is formed integrally with the installation cavity 110, and a positioning groove 600 for accommodating the boss 500 is provided on the dowel seat 200. When the boss 500 is embedded in the positioning groove 600, the guide hole 220 and the installation hole 120 are aligned to facilitate the movable pin 300 to pass through the installation hole 120, which plays a role in auxiliary positioning and facilitates installation. The size of the boss 500 matches the size of the positioning groove 600, and the additional connection method of the buckle without reverse locking only plays a role in auxiliary positioning, and does not increase. The boss 500 is provided with a chamfer to facilitate entry and exit of the positioning groove 600. It is foreseeable that positioning can also be performed by a positioning bead plus a groove. During the operation, when performing anastomosis, the blade 201 will move to the front end of the stroke and then return, and the fixation of the olecranon body 100 will be cancelled within a few seconds. At this time, the olecranon body 100 relies on the cooperation of the boss 500 and the positioning groove 600 to prevent the olecranon body 100 from falling off the front end of the dowel seat 200.

[0041] Reference Figures 1 to 8 As shown, it can be understood that both the boss 500 and the positioning groove 600 are cross-shaped. The cross-shaped boss 500 and the positioning groove 600 are used to cooperate with each other, which is conducive to improving the stability of positioning and preventing the boss 500 from shaking in the positioning groove 600.

[0042] Reference Figures 1 to 6 As shown, it can be understood that there are two groups of symmetrical bosses 500 and positioning grooves 600. Providing two groups of bosses 500 and positioning grooves 600 is conducive to improving the stability of positioning and preventing the hawk beak body 100 from shaking after being sleeved on the front end of the shaking nail seat 200.

[0043] Reference Figures 1 to 6 As shown, it can be understood that the two positioning grooves 600 are respectively arranged on the upper and lower surfaces of the dowel seat 200.

[0044] Reference Figures 1 to 6 As shown, it can be understood that there are two groups of movable pins 300 and mounting holes 120 symmetrically arranged. The two groups of movable pins 300 and mounting holes 120 can make the fixation of the hawkbill body 100 and the dowel seat 200 more reliable.

[0045] Reference Figures 5 to 8As shown, it can be understood that the elastic member 400 includes a U-shaped spring 410 and a V-shaped spring 420, and the V-shaped spring 420 is embedded in the opening of the U-shaped spring 410. The two ends of the U-shaped spring 410 and the two ends of the V-shaped spring 420 are respectively welded and fixedly connected, and the openings of the U-shaped spring 410 and the V-shaped spring 420 are both set backward, and the front-to-back direction size of the V-shaped spring 420 is smaller than the front-to-back direction size of the U-shaped spring 410, and the left and right sides of the U-shaped spring 410 are respectively connected to the movable pin 300 by welding. The blade 201 can push the V-shaped spring 420 to deform forward, pull the opening of the U-shaped spring 410 to close, and thus drive the movable pin 300 to retract into the mounting hole 120. The spring is used to realize the transmission of the front-to-back movement of the blade 201 to the left-right movement of the movable pin 300, saving manufacturing costs. And there is no need to make too many changes to the production process of the existing anvil seat 200, and only two punching processes need to be added to the existing production process.

[0046] Reference Figures 6 to 8 As shown, it can be understood that a push rod 202 is welded at the front end of the blade 201, and the length of the push rod 202 matches the stroke of the blade 201, so that the push rod 202 can push the V-shaped spring 420 and move the movable pin 300 to the second position. The size of the guide block connected to the lower end of the existing blade 201 matches the hollow guide groove 210, which is not suitable for directly pushing the V-shaped spring 420, so a push rod 202 is welded to push the V-shaped spring 420 to drive the U-shaped spring 410 to deform. The advantage is that there is no need to change the existing blade 201, and only a push rod 202 needs to be welded on the slider below the existing blade 201, saving manufacturing costs.

[0047] Reference Figures 1 to 6 As shown, it can be understood that the side of the anvil seat 200 body and the side of the olecranon body 100 are set as arc surfaces. The arc surfaces are set to prevent sharp edges from damaging tissues during surgery.

[0048] Reference Figures 1 to 8 As shown, it can be understood that the shape of the installation cavity 110 matches the shape of the front end of the anvil 200. The front end of the anvil 200 is generally a narrowed arc shape, so the shape of the installation cavity 110 is also set to a concave arc shape.

[0049] Working principle: When installing the hawk beak body 100, first push the blade 201 to the front end of the blade 201 stroke without installing the nail magazine. At this time, the push rod 202 pushes the V-shaped spring 420 forward and drives the U-shaped spring 410 to deform, and the movable pin 300 moves to the second position. Then the hawk beak body 100 is sleeved to the front end of the nail support 200, and the boss 500 is embedded in the positioning groove 600 to position the hawk beak. Then the blade 201 is moved backward, and the movable pin 300 is pushed out of the side of the nail support 200 by the U-shaped spring 410. After the movable pin 300 enters the installation hole 120, it can position the hawk beak body 100 in the front and rear directions, and the installation is completed.

[0050] When disassembling the hawk beak body 100, the blade 201 is pushed to the front end of the blade 201 stroke, the push rod 202 pushes the V-shaped spring 420 forward and drives the U-shaped spring 410 to deform, the movable pin 300 moves to the second position, the front and rear direction fixation of the hawk beak body 100 is cancelled, and the hawk beak body 100 is removed.

[0051] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
