A button 16 is slidably installed on the upper end of the rotating block 6, and a slave gear 17 is fixedly installed inside the rotating block 6. A driving motor 18 is fixedly installed inside the fixed block 4, and a moving gear 19 is fixedly installed on the output end of the driving motor 18. The push rod 9 and the moving block 10 are symmetrically arranged in two groups about the horizontal center axis of the moving rod 8, and the moving block 10 is slidably connected with the two groups of clamping rods 7. The moving part 11 forms an elastic structure with the moving block 10 through the supporting spring 12, and the moving part 11 forms a clamping structure with the clamping rod 7 through the card slot 13, and the card slot 13 is equidistantly arranged inside the clamping rod 7. The sliding sleeve 14 forms a traction structure with the moving part 11 through the traction rope 15, and the traction rope 15 is symmetrically arranged in two groups about the upper end of the horizontal center axis of the sliding sleeve 14, and the traction rope 15 is fixedly connected to the moving part 11, the slave gear 17 is meshed with the moving gear 19, and the moving gear 19 is located in the middle position on the left side of the rotating block 6.

[0027] according to Figure 1-6When using the laparoscopic needle holder with adjustable handle angle, the needle holder is first placed at the position where work is required. Before the medical staff uses the needle holder, the angle between the two sets of clamping rods 7 and the fixed tube 1 needs to be adjusted to the required position according to the medical staff's usage habits. Before adjusting the angle, the moving part 11 needs to be separated from the card slot 13. During this process, the medical staff slides the sliding sleeve 14 and causes the sliding sleeve 14 to drive the moving part 11 to move through the traction rope 15. During the movement of the moving part 11, the support spring 12 is stretched and the moving part 11 is separated from the card slot 13. After the moving part 11 is separated from the card slot 13, the angle can be adjusted. During the angle adjustment process, the medical staff The staff supplies power to the driving motor 18 through the power port 5, and presses the button 16 after the driving motor 18 is powered. At this time, the driving motor 18 will work and drive the moving gear 19 to rotate. During the rotation of the moving gear 19, the rotating block 6 can be driven to rotate by the gear 17. During the rotation of the rotating block 6, the angle between the clamping rod 7 and the fixed tube 1 can be adjusted. After adjusting to the required angle, release the button 16, and then release the sliding sleeve 14. The stretched support spring 12 will shrink and make the moving part 11 engage with the slot 13 again.

[0029] according to Figure 1-2 When the medical staff uses the needle holder, the medical staff can squeeze the two groups of clamping rods 7 to make the moving rod 8 move inside the fixed tube 1 through the push rod 9, and the moving rod 8 can rotate and cooperate with the fixed tooth 2 to clamp the suture needle during the movement of the moving rod 8 (the moving rod 8 drives the moving tooth 3 to move is a prior art, which has been disclosed and does not need to be further explained). In the process of using the suture needle to suture the wound, the medical staff needs to clamp the suture needle many times. In the process of the two groups of clamping rods 7 approaching each other, the moving rod 8 will be pushed to move, and the moving rod 8 will drive the reset block 20 to move during the movement. In the process of the reset block 20 moving, the reset spring 21 will be squeezed and the reset spring 21 will be contracted. After the two groups of clamping rods 7 move away from each other, the compressed reset spring 21 will expand and push the moving rod 8 to move through the reset block 21, so that the moving tooth 3 is actively separated from the fixed tooth 2, so that it is convenient for the medical staff to clamp the suture needle next time, thereby effectively improving the convenience of using the needle holder and increasing the overall practicality.
