State)；
Along the sectional view of handle axis, (the first protrusion is in open shape to the blood vessel pull device that Fig. 3 is Fig. 1 with recessed portion
State).
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
The blood vessel pull device of the present embodiment is as shown in Figure 1, include：Handle 1, connecting rod 2 and traction portion 3, wherein retract
The head in portion 3 is arc-shaped, and head to tail portion is in diminishing trend, and tail portion and one end of connecting rod 2 are integrally formed connection, connect
The other end of extension bar 2 is integrally formed with one end of handle 1 and connects, and 3 surface of traction portion is formed with knurled pattern 31.
The head in the traction portion 3 of the blood vessel pull device of the present embodiment is arc-shaped, and when traction will not damage blood vessel and its week
The tissue enclosed, and knurled pattern 31 can increase the friction on 3 surface of blood vessel and traction portion, and traction is made to be more prone to.
It is arranged with several recessed portions 12 respectively on two opposite sides on handle 1, anti-skidding effect is played when hand-held.
As shown in Figures 2 and 3, the blood vessel pull device of the present embodiment further includes：Support clip 4, on handle 1 it is opposite in addition
Two sides are respectively formed with sliding slot 11.Support clip 4 includes：Gland 43, the first clamping head 41 and the second clamping head 42, Gu
Determine first 43 one end to be formed there are two symmetrical protrusion 44, two protrusions 44 are respectively slidably caught in two sliding slots 11
It is interior.First clamping head 41 is located between two protrusions 44, and 41 top of the first clamping head is equipped with for being caught in the recessed portion 12
