Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, 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 embodiment in the utility model, those of ordinary skill in the art are without creative efforts
All other embodiments obtained shall fall within the protection scope of the present invention.
The neural pull device of the present embodiment as shown in Figure 1, including：Handle 1 and traction portion 2, the one end in traction portion 2 and hand
One end of handle 1 is integrally formed formula connection, as shown in Fig. 2, the other end in traction portion 2 is in diminishing trend, and end Cheng Yuan
Cambered surface, the radius of the arc surface is 0.6mm~0.8mm.
The head in the traction portion 2 of the neural pull device of the present embodiment is retracted in the cambered surface that radius is 0.6mm~0.8mm
When, nerve and the tissue of surrounding can either be pushed aside, and will not injured nerve and surrounding tissue.
In the present embodiment, traction portion 2 is in curved arc, it is easier to the end that traction portion 2 reduces be made to extend into affected part and led
Open nerve.
Several recessed portions 12 are arranged with respectively on two opposite sides on handle 1, and anti-skidding effect is played when hand-held.
As shown in Figures 3 and 4, the neural pull device of the present embodiment further includes：Support clip 3, on handle 1 it is opposite in addition
Two sides are respectively formed with sliding slot 11.Support clip 3 includes：Gland 33, the first clamping head 31 and the second clamping head 32, Gu
Fixed first 33 one end is formed there are two symmetrical protrusion 34, and two protrusions 34 are respectively slidably caught in two sliding slots 11
It is interior.First clamping head 31 is located between two protrusions 34, and 41 top of the first clamping head is equipped with to be caught in the recessed portion 12
The first protrusion 35, and top, less than protrusion 34, the first clamping head 31 is rotatably installed in gland 33, and with fixation
First spring 36 is installed, to form the first clamp structure between first 33.The middle part of gland 33 is equipped with through hole 37, the second clamping
First 32 are located at the other end of the gland 33, and the second clamping head 32 is rotatably installed in gland 33, and and gland
