[0022] The utility model provides a technical solution: as shown in Figure 1, Figure 2 and Figure 3 As shown, in this embodiment, the laparoscopic clip applier includes an outer tube 1, which is characterized in that: an adjustment component 8 is installed at one end of the outer tube 1, and the adjustment component 8 includes two extension plates 801 fixedly connected to the outer wall of the top of the outer tube 1, and the two extension plates 801 are respectively located at two ends of the outer tube 1, and a mounting tube 802 is rotatably connected between the two extension plates 801, and a screw 803 is threadedly connected to the rotating end of the mounting tube 802, and the screw 803 is located at one end of the outer tube 1, and the screw 803 can enter the mounting tube 802, and a knob 804 is coaxially fixed to the end of the screw 803 away from the outer tube 1, and the diameter of the knob 804 is larger than the diameter of the screw 803.

[0023] A fixing ring 805 is fixedly connected to the outer wall of one end of the knob 804 close to the outer tube 1. The fixing ring 805 can contact the rotating end of the outer tube 1 and the mounting tube 802. The fixing ring 805 is made of rubber material and can increase the static friction between the knob 804 and the outer tube 1 and the mounting tube 802, thereby further increasing the fixing effect of the mounting tube 802.

[0024] If the head tilt angle of the mounting tube 802 needs to be adjusted, the mounting tube 802 can be turned by simply moving it, and the mounting tube 802 will rotate in the outer tube 1. After the adjustment is completed, the screw 803 is driven to rotate by the knob 804, and the screw 803 can rotate into the rotating end of the mounting tube 802, and then the fixing ring 805 contacts the surface of the outer tube 1. As the screw 803 continues to rotate, the knob 804 can drive the fixing ring 805 to tightly squeeze the outer wall of the outer tube 1, and the position of the mounting tube 802 will also be fixed.

[0025] like Figure 2 and Figure 4 As shown, the inner walls at both ends of the mounting tube 802 are rotatably connected to the same chuck 3, the chuck 3 is composed of two clamping arms, the bottom of the two clamping arms of the chuck 3 are rotatably connected to a connecting rod 4, the two connecting rods 4 are rotatably connected to each other, and the inner wall at one end of the mounting tube 802 is fixedly connected to a mounting plate 6, a driving rod 5 is slidably inserted in the mounting plate 6, and the two connecting rods 4 are rotatably connected to the outer wall at one end of the driving rod 5.

[0026] A spring 7 is sleeved on the outside of the driving rod 5, and two ends of the spring 7 are fixedly connected to the driving rod 5 and the mounting plate 6 respectively, so that the device has a reset function.

[0027] Press the movable handle 2, one end of the movable handle 2 drives the driving rope 902 to move outward, and the driving rope 902 can drive the ring 901 and the driving rod 5 to move toward the bottom of the mounting plate 6, and the driving rod 5 drives the two connecting rods 4 to move downward, and the two connecting rods 4 can drive the two chucks 3 to move closer to each other, thereby completing the clamping work, and then releasing the movable handle 2, the spring 7 will also restore its length to drive the driving rod 5 back to its original position, and then the chuck 3 will also return to its original state.

[0028] like Figure 4 As shown, an adaptation component 9 is installed at the bottom of the mounting plate 6, and the adaptation component 9 includes a ring 901 set at one end of the bottom of the driving rod 5, and a driving rope 902 is sleeved in the ring 901. One end of the driving rope 902 passes through the outer tube 1 and extends outward. One end of the outer tube 1 is rotatably connected to the movable handle 2, and one end of the driving rope 902 is fixedly connected to the top end of the movable handle 2.

[0029] The ring 901 rotates with the mounting tube 802 . Since the driving rope 902 and the ring 901 are mutually sleeved, the rotation of the ring 901 will not be hindered by the driving rope 902 , thereby ensuring that the subsequent clamping work is not affected by the angle change of the mounting tube 802 .

[0030] The utility model provides a laparoscopic clip applier, and the specific working principle is as follows:

[0031] When the device is working, if the tilt angle of the head of the mounting tube 802 needs to be adjusted, the mounting tube 802 only needs to be turned, and the mounting tube 802 will rotate in the outer tube 1. After the adjustment is completed, the screw 803 is driven to rotate by the knob 804, and the screw 803 can rotate into the rotating end of the mounting tube 802, and then the fixing ring 805 contacts the surface of the outer tube 1. As the screw 803 continues to rotate, the knob 804 can drive the fixing ring 805 to tightly squeeze the outer wall of the outer tube 1. At this time, the position of the mounting tube 802 will also be fixed, and the ring 901 will also rotate with the mounting tube 802. 901 are mutually sleeved together, and the rotation of the ring 901 will not be hindered by the driving rope 902, which can ensure that the subsequent clamping work is not affected by the angle change of the mounting tube 802. Finally, press the movable handle 2, and one end of the movable handle 2 drives the driving rope 902 to move outward, and the driving rope 902 can drive the ring 901 and the driving rod 5 to move toward the bottom of the mounting plate 6. The driving rod 5 drives the two connecting rods 4 to move downward, and the two connecting rods 4 can drive the two chucks 3 to move closer to each other, thereby completing the clamping work, and then release the movable handle 2, the spring 7 will also restore its length to drive the driving rod 5 back to its original position, and then the chuck 3 will also return to its original state.
