Wherein, several recessed portions are arranged with respectively on two sides opposite on the handle.
Wherein, further include:Support clip, other two opposite side is respectively formed with sliding slot on the handle, described Support clip includes:Gland, the first clamping head and the second clamping head, there are two symmetrical convex for one end formation of the gland Go out portion, two protrusions are respectively slidably caught in two sliding slots, and first clamping head is located between two protrusions, institute It states and the first protrusion for being caught in the recessed portion is equipped at the top of the first clamping head, and top is less than the protrusion, described the One clamping head is rotatably installed in gland, and the first spring is equipped between the gland, to form the first folder Hold structure;The middle part of the gland is equipped with through hole, and second clamping head is located at the other end of the gland, the second clamping Head is rotatably installed in gland, and is equipped with second spring between the gland, to form the second clamp structure, The second protrusion is equipped at the top of second clamping head, and the second protrusion passes through the opening of the side wall of the through hole.
The traction size portion of the neural pull device of the utility model is arc-shaped, and when traction will not injured nerve and its surrounding Tissue.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is a kind of neural pull device structure diagram of the utility model;
Fig. 2 is the head schematic diagram at dotted-line ellipse frame in Fig. 1;
Along the sectional views of handle axis, (the first protrusion is in tight lock shape to the neural pull device that Fig. 3 is Fig. 1 with recessed portion State);
Fig. 4 be Fig. 1 neural pull device along handle axis sectional view (first protrusion with recessed portion be in open shape State).
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 Second spring 39 is installed between 33, to form the second clamp structure, 32 top of the second clamping head is equipped with the second protrusion 38, and the Two protrusions 38 pass through the opening of the side wall of through hole 37.
By pressing the first clamping head 31, the first spring 36 shrinks, the first protrusion 35 is made to leave recessed portion 12, is passed through at this time Two protrusions 34 slide to adjust the position being clamped on handle 1 in two sliding slots 11, and the first clamping head is decontroled after regulating 31, the rebound of the first spring 36 jacks up, and the first protrusion 35 is made to be stuck in recessed portion 12.Press the second clamping head 32, second spring 39 It shrinks, the second protrusion 38 positioned at top is made to leave through hole 37, the support arm retracted on frame is inserted in through hole 37 to suitable position It puts, decontrols the second clamping head 32, the second protrusion 38 stretches into the side of 37 internal pressure compact schemes arm of through hole, so just leads entire nerve Opening apparatus has neatly been fixed on traction frame, is helped without being led again by manpower, further saves space.
