Connected, the blind hole 23 is opened on the connecting rod 1 rear side, and the rear end of the connecting rod 1 is provided with a deflection hole 24 that communicates with the blind hole 23, the deflection hole 24 is slidably connected with an elastic rod 25, and the right end of the elastic rod 25 penetrates the connecting rod 1 and is arranged inside the casing 17 , a miniature camera 26 is installed on the left end of the elastic rod 25 .

Working principle: When using the minimally invasive endoscopic stapler for easy positioning, first insert the connecting plate 9 into the groove 18, at this time the first sliding rod 4 penetrates through the casing 17 and is engaged with the first driving device 19, and the first sliding rod 4 is engaged with the first driving device 19. The second sliding rod 7 penetrates through the casing 17 and is engaged with the second driving device 20, while the worm 22 is engaged with the second coil 13, the connecting rod 1 of the endoscopic stapler is inserted into the puncture tube, the elastic rod 25 is pushed, and the elastic force The rod 25 pushes the micro camera 26 to move to the left along the blind hole 23. At this time, the left end of the elastic rod 25 is deformed and pushes the micro camera 26 to leave the connecting rod 1 through the deflection hole 24, and then the micro camera 26 captures the image around the endoscopic stapler. The image is sent to the doctor. The micro camera 26 is close to the endoscopic trocar, so that the doctor can quickly and accurately understand the environment around the endoscopic stapler. The leftmost end fits the leftmost end of the opening, the external power supply is turned on, the first driving device 19 is activated, the first driving device 19 pushes the first sliding rod 4 to slide, and the first sliding rod 4 pulls the upper collet 3 so that the The connecting rod 1 cooperates with the diseased tissue in the clamping opening 2, and activates the second driving device 20. The second driving device 20 pulls the cutting knife 6 through the second sliding rod 7 to move to the right along the first knife groove 5, while the cutting knife 6 on the cutting knife 6 moves to the right. The nail pressing bar 28 squeezes the nail plate 15 glued on the guide rope 11, so that the nail plate 15 moves upward and is separated from the connecting rod 1 through the nail outlet 27, and the staples 16 on the nail plate 15 are matched with the nail anvil seat 29. Suture the diseased tissue, then the cutting knife 6 slides along the second knife groove 8 to complete the cutting of the diseased tissue, the upper side of the cutting knife 6 slides into the second knife groove 8, and the second knife groove 8 cooperates with the cutting knife 6 The position of the upper collet 3 is limited, so that the clamping between the upper collet 3 and the connecting rod 1 is more tightened, until the cutting knife 6 moves to the rightmost end of the diseased tissue, and then the second driving device 20 runs in the reverse direction to make the cutting knife 6 move in the opposite direction. 6. Reset, through the above operations, the suture distance and the cutting distance can be rotated according to the length of the diseased tissue, so as to avoid useless staples 16 scattered in the abdominal cavity of the patient, and it is safer to use. After completing one anastomosis, start the driving motor 21 and the driving motor 21 The second spool 13 is driven to rotate by the worm 22 , the second spool 13 rewinds the guide rope 11 , and the guide shaft 14 guides the movement track of the guide rope 11 , so that the leftmost nail plate 15 on the guide rope 11 follows the nail groove 10 Move to the left until the nail plate 15 moves to the leftmost end of the nail outlet 27, and it is possible to perform multiple anastomosis without repeatedly replacing the nail box, which is more convenient to use.
