[0021] The blocking wire traction hook 2 comprises a traction hook 8, and a hook closing claw 9 is movably arranged on the opening side of the traction hook 8. The hook closing claw 9 is composed of an arc-shaped claw body 12, one end of the claw body 12 is provided with a claw rotating connection hole 13, and the claw body 12 is rotatably connected with a closing claw hinged shaft 11 in a closing claw hinged groove 10 arranged at the root of the traction hook 8 through the claw rotating connection hole 13; and the claw body 12 is further provided with a claw reset spring groove 14 on the side facing the traction hook 8, and a reset spring is arranged between the claw reset spring groove 14 and the closing claw hinged shaft 11. Further, the hook closing claw 9 is rotatably arranged in the closing claw hinged groove 10 at the root of the traction hook 8 through the claw rotating connection hole 13, and the wrapped blocking wire 6 that has been wrapped around the blood vessel is hooked by the traction hook 8 of the blocking wire traction hook 2, and the reset elastic force of the reset spring arranged in the claw reset spring groove 14 is used to form a closed space between the hook closing claw 9 and the traction hook 8, so as to facilitate the surgeon to operate the guide wire device 1 and pull out the wrapped blocking wire 6 from the traction sleeve 4.

[0022] Meanwhile, the guide wire slender rod 7 of the guide wire device 1 and the blocking wire traction hook 2 at the front end thereof are movably and freely inserted into the flexible traction sleeve 4; and according to the specific use requirement, the hardness of the traction sleeve 4 needs to be moderate, neither too hard nor too soft. In addition, the traction sleeve 4 is further provided with a wire locker 5 near the rear end of the holding handle 3 for locking the blocking wire and applying extrusion force. The wire locker 5 is composed of a cylindrical wire locker connecting body 15, the front end of the wire locker connecting body 15 is provided with a sleeve connecting slot 25 connected with the traction sleeve 4; and the rear end of the wire locker connecting body 15 is provided with a blocking wire first through hole 16, and the blocking wire first through hole 16 and the sleeve connecting slot 25 are in communication with each other.

[0023] The rear end of the locking wire connector 15 of the locking wire device 5 is fixedly provided with a locking wire fixed column 17, and the upper end of the locking wire fixed column 17 is connected with a locking wire movable column 19 which is movably arranged on the other side and has a certain elasticity through a locking wire arc-shaped connecting section 18. Moreover, the lower end of the locking wire movable column 19 is provided with a locking wire insertion block 21 which faces the inner side of the blocking wire first through hole 16, and correspondingly, the lower end of the locking wire fixed column 17 is provided with a locking wire insertion slot 22 which faces the inner side of the blocking wire first through hole 16. The lower end of the locking wire movable column 19 is also provided with a locking wire pressing part 20 which faces the outer side of the blocking wire first through hole 16. Thus, the locking wire device 5 is arranged at the end of the traction sheath tube 4 by using the sleeve connecting insertion slot 25, and the end of the winding blocking wire 6 which is pulled by the guide wire device 1 is pulled out from the blocking wire first through hole 16 at the rear end of the locking wire connector 15 inside the traction sheath tube 4.

Then, the traction sheath tube 4 is pressed towards the blood vessel by using the locking wire device 5, so that the winding end of the winding blocking wire 6 produces a tight effect on the blood vessel.

[0024] Moreover, the inner side of the locking wire fixed column 17, the locking wire arc-shaped connecting section 18 and the locking wire movable column 19 forms a hollow cavity 24 for assisting operation, and the locking wire arc-shaped connecting section 18 is provided with a blocking wire second through hole 23 which is coaxially arranged with the blocking wire first through hole 16. Thus, the end of the winding blocking wire 6 which is pulled by the guide wire device 1 is pulled out from the locking wire device 5 through the coaxially arranged blocking wire first through hole 16 and the blocking wire second through hole 23 at the rear end of the locking wire connector 15 at one time, so as to facilitate the locking of the end of the winding blocking wire 6. Moreover, the traction process of the guide wire device 1 can be assisted by the hollow cavity 24, and the loosening operation of the end of the winding blocking wire 6 after the operation is facilitated. Meanwhile, the bottom side of the lower end of the locking wire movable column 19 which is opposite to the end surface of the locking wire connector 15 is provided with a plurality of locking clamping slots 27, and correspondingly, the end surface of the locking wire connector 15 is provided with locking positioning protrusions 26 which are used for cooperating with the locking clamping slots 27. Thus, the locking position of the locking wire movable column 19 is fixed by the cooperation and clamping of the locking clamping slots 27 at the bottom side of the lower end of the locking wire movable column 19 and the locking positioning protrusions 26 at the end surface of the locking wire connector 15, so as to facilitate the use of the device. When the clamping position of the locking wire movable column 19 needs to be loosened, the locking wire movable column 19 can be moved outward by inserting a finger into the hollow cavity 24, so as to release the locking of the locking positioning protrusions 26.

[0025] The blood vessel blocking set is used as follows. Firstly, the surgeon identifies and avoids the blood vessel region prone to bleeding, then anatomically separates the proximal and distal ends of the blood vessel, and then uses the winding blocking line 6 with a larger diameter and smooth surface to gently wind the blood vessel. Then, the surgeon holds the handle 3 to operate the wire guide 1 inserted in the traction sleeve 4, and then uses the blocking line traction hook 2 at the front end of the wire guide 1 extending out of the traction sleeve 4 to hook the winding blocking line 6 wound on the blood vessel at a distance of 5-10 cm from the end side. Then, the surgeon operates the wire guide 1 to pull the winding blocking line 6 out of the traction sleeve 4, and makes the wire guide 1 and the end of the winding blocking line 6 pulled out of the wire guide 1 through the blocking line first through hole 16 and the blocking line second through hole 23 coaxially arranged at the rear end of the wire locking connecting body 15 of the wire locking device 5.

[0026] After the end of the winding blocking line 6 is pulled out of the blocking line first through hole 16 and the blocking line second through hole 23 of the wire locking device 5 by the blocking line traction hook 2 of the wire guide 1, the wire locking pressing part 20 of the wire locking movable column 19 is pressed, so that the end of the winding blocking line 6 is locked by the cooperation and extrusion of the wire locking plug 21 at the lower end of the wire locking movable column 19 and the wire locking slot 22 at the lower end of the wire locking fixed column 17, and the wire locking position of the wire locking movable column 19 is fixed by the cooperation and clamping of the locking clamping groove 27 at the lower end of the wire locking movable column 19 and the locking positioning protrusion 26 at the end surface of the wire locking connecting body 15. After the end of the winding blocking line 6 pulled out is locked by the wire locking device 5, the wire locking device 5 is used to apply a pressing force to the traction sleeve 4 with a moderate hardness towards the blood vessel, so that the winding end of the winding blocking line 6 tightens the blood vessel (similar to the effect of ligation), so as to block the blood vessel. After the blood vessel is blocked, the surgeon can cut the diseased blood vessel and suture the blood vessel stump. After the suture is completed, the wire locking device 5 is released, and the winding blocking line 6 is unlocked, so that the blood vessel is restored to be unblocked.
