After the medical staff determines the operation position again, the rotation disc 62 is rotated through the anti-slip groove 622, due to the threaded connection between the thread movable column 611 and the thread rotating hole 621, the thread movable column 611 is driven to move upwards through the thread rotating hole 621 while the rotation disc 62 is rotated, the top end of the thread movable column 611 enters the locking rod accommodating groove 631 formed in the center of the protection cap 63, so that the whole locking rod 61 can move upwards, the thread movable column 611 moves upwards to drive the locking rod 61 to gradually ascend and separate from the fixed locking hole 51, the transmission connecting rod 5 is unlocked, and the transmission connecting rod 5 can move to excite the mechanism in the head anastomosis assembly 1.

After the medical staff determines the operation position again, the part to be sutured is clamped into the gap of the head anastomosis component 1 of the linear anastomat, after the trigger 82 is moved a slight distance in a direction away from the grip 81, the lock ring 84 is removed from the lock ring engaging groove 821, the lock of the trigger 82 by the lock ring 84 is released, and after the position is confirmed again, by depressing the firing trigger 82, the firing trigger 82 is moved toward the grip 81 about the firing trigger mounting post 415, causing the depressed firing bar 822 to move downward to exert pressure on the depressed firing plate 83, since the first and

second sliders

831 and 832 are respectively disposed inside the first and

second rail grooves

414 and 416, so that the whole lower actuating plate 83 moves downwards under the combined restriction of the first slider 831, the second slider 832, the first rail groove 414 and the second rail groove 416, and the lower actuating plate 83 moves downwards to press the bottom end locking block 73 to move downwards under the action of the lifting spring 732.

The bottom end locking block 73 unlocks the spring telescopic block 717 when moving downwards under pressure, so that the whole impact front end 71 is unlocked, the excitation spring 722 is not compressed any more, the excitation spring 722 gives a large force to the movable compression block 713, the movable compression block 713 drives the impact spring 712 to further drive the impact block 711 to move rapidly, the impact block 711 moves rapidly to impact the transmission link 5, the speed is rapidly transmitted to the head anastomosis component 1 through the transmission link 5, and the excitation of the tail control component 3 to the suture system in the head anastomosis component 1 is completed.

The main push plate 15 in the movable anastomosis plate 12 is driven to advance by the speed transmitted by the transmission connecting rod 5, the main push plate 15 advances to push the whole movable anastomosis plate 12 to move towards the nail anvil 13 by the spring push column 151 arranged on the main push plate 15, the spring can rebound when the main push plate 15 pushes the movable anastomosis plate 12 to move in the direction of the nail anvil 13 due to the arrangement of the spring push column 151, the anastomosis nail push plate push column 152 synchronously pushes the anastomosis nail push plate 16 to advance, and pushes the anastomosis nail push plate 16 to continue to move in the rebounding process of the movable anastomosis plate 12, the anastomosis nail push plate 16 moves to make the anastomosis nail push column 161 arranged on the anastomosis nail push plate 161 push the anastomosis nails in the corresponding anastomosis nail groove 141 on the nail bin 14 to eject, the anastomosis nails penetrate the skin and meet the corresponding bending groove 131 on the nail anvil 13, the suturing operation on the affected part is finished after the suturing operation is finished in a linear type, the whole anastomat is recycled by the handgrip 81 after the suturing operation is finished, namely, the sewing operation of the whole affected part is completed.
