[0021] To describe in detail the technical content, achieved purpose and effects of the present utility model, the following is described in conjunction with the embodiments and with reference to the drawings.

[0022] Please refer to Figure 1 and Figure 2 , a cervical retractor with a light source channel, comprising a hook body 1, a support rod 2 and a fixed hook 3 connected in sequence. A light source through-hole 111 is provided on the hook body 1. One end of the light source through-hole 111 communicates with the surface of the hook body 1 away from the fixed hook 3, and the other end of the light source through-hole 111 communicates with the surface of the support rod 2 away from the hook body 1.

[0023] As can be seen from the above description, the beneficial effects of the present utility model are as follows: During the use of the cervical retractor with a light source channel, the light emitted by the light source above can enter through the opening on the side of the support rod 2 of the light source through-hole 111, and then exit through the opening on the outer side of the hook body 1 of the light source through-hole 111, illuminating the intervertebral space in front of the hook body 1, facilitating the surgeon to clearly see the surgical site, and effectively improving the safety of the surgery.

[0024] Further, the number of the light source through-holes 111 is multiple.

[0025] As can be seen from the above description, multiple light source through-holes 111 can allow more light to pass through, further enhancing the brightness of the surgical site.

[0026] Furthermore, the light source through-hole 111 is circular or elliptical.

[0027] As can be seen from the above description, the shape of the light source through-hole 111 can be selected according to actual usage needs.

[0028] Furthermore, the hook body 1 and the fixed hook 3 are provided on the same side of the support rod 2.

[0029] As can be seen from the above description, arranging the fixed hook 3 and the hook body 1 on the same side of the support rod 2 can reduce the width of this cervical retractor and the occupied space.

[0030] Furthermore, the hook body 1 and the support rod 2 are of an integrally formed one-piece structure.

[0031] As can be seen from the above description, the integrally formed one-piece structure can reduce the production and assembly steps, improve the overall strength, and at the same time facilitate the cleaning of this cervical retractor.

[0032] Furthermore, the fixed hook 3 and the support rod 2 are of an integrally formed one-piece structure.

[0033] As can be seen from the above description, the integrally formed one-piece structure can reduce the production and assembly steps, improve the overall strength, and at the same time facilitate the cleaning of the cervical retractor.

[0034] Furthermore, the hook body 1 includes a blocking portion 11 and an inward buckle 12. One end of the blocking portion 11 is connected to the inward buckle 12. The inward buckle 12 is arranged on the side of the blocking portion 11 close to the support rod 2. The other end of the blocking portion 11 is connected to the support rod 2.

[0035] As can be seen from the above description, the blocking portion 11 is used to block the patient's tissue from closing towards the surgical site. The arrangement of the inward buckle 12 can better pull apart the soft tissue, making it easier for light to enter deep into the intervertebral disc and the spinal canal.

[0036] Furthermore, the blocking portion 11 and the inward buckle 12 are of an integrally formed one-piece structure.

[0037] As can be seen from the above description, the integrally formed one-piece structure can reduce the production and assembly steps, improve the overall strength, and at the same time facilitate the cleaning of this cervical retractor.

[0038] Furthermore, the included angle between the blocking portion 11 and the inward buckle 12 ranges from 168° to 172°.

[0039] Furthermore, the fixed hook 3 is arc-shaped.

[0040] As can be seen from the above description, the arc-shaped structure facilitates the hanging of the fixed hook 3 on an external object.

[0041] Please refer to Figure 1 and Figure 2 For the first embodiment of the present utility model: A cervical retractor with a light source channel, which includes a hook body 1, a support rod 2, and a fixed hook 3 connected in sequence. A light source through hole 111 is provided on the hook body 1. One end of the light source through hole 111 communicates with the surface of the hook body 1 away from the fixed hook 3, and the other end of the light source through hole 111 communicates with the surface of the support rod 2 away from the hook body 1. Specifically, the hook body 1 and the fixed hook 3 are arranged on the same side of the support rod 2. The fixed hook 3 is arc-shaped. The hook body 1 and the support rod 2 are an integrally formed one-piece structure; the fixed hook 3 and the support rod 2 are an integrally formed one-piece structure.

[0042] The hook body 1 includes a blocking portion 11 and an inner buckle 12. One end of the blocking portion 11 is connected to the inner buckle 12. The inner buckle 12 is arranged on the side of the blocking portion 11 close to the support rod 2. The other end of the blocking portion 11 is connected to the support rod 2. The length direction of the blocking portion 11 is perpendicular to the length direction of the support rod 2. The light source through hole 111 communicates with the outer side surface of the blocking portion 11. The blocking portion 11 and the inner buckle 12 are an integrally formed one-piece structure.

[0043] The value range of the included angle between the blocking portion 11 and the inner buckle 12 is 168° - 172°. In this embodiment, the included angle between the blocking portion 11 and the inner buckle 12 is 170°.

[0044] In this embodiment, the light source through hole 111 is circular with a diameter of 2.5 mm. In other embodiments, it is also feasible to set the light source through hole 111 as an ellipse; the value range of the diameter of the light source through hole 111 is 2 - 3 mm.

[0045] In order to increase the light passing amount, the number of the light source through holes 111 is multiple. In this embodiment, the number of the light source through holes 111 is two. The axial directions of the two light source through holes 111 are parallel, and the center distance between the two light source through holes 111 is 14 mm. In other embodiments, the number of the light source through holes 111 can be set to three, four or more.

[0046] The value range of the distance between the end of the hook body 1 away from the support rod 2 and the surface of the support rod 2 away from the hook body 1 is 70 - 90 mm. In this embodiment, this distance is 80 mm. The value range of the distance between the end of the fixed hook 3 away from the support rod 2 and the surface of the support rod 2 away from the fixed hook 3 is 35 - 45 mm. In this embodiment, this distance is 40 mm. The value range of the width of the support rod 2 is 15 - 25 mm. In this embodiment, the width of the support rod 2 is 20 mm. The value range of the distance between the surfaces of the hook body 1 and the fixed hook 3 away from each other is 130 - 170 mm. In this embodiment, this distance is 150 mm.

[0047] In order to prevent the cervical retractor from scratching the patient's tissue, the outer edges of the hook body 1, the support rod 2, and the fixed hook 3 are all provided with rounded corners.

[0048] In order to prevent the surface reflection of the present cervical retractor from affecting the surgeon, the outer surfaces of the hook body 1, the support rod 2, and the fixed hook 3 of the present cervical retractor are all passivated, while the light source through hole 111 is not passivated, so that more light can pass through the light source through hole 111.

[0049] In summary, during the use of the cervical retractor with a light source channel provided by the present utility model, the light emitted by the light source above can enter through the opening of the light source through hole on the side of the support rod, and then exit from the opening of the light source through hole on the outer side of the hook body, illuminating the intervertebral space in front of the hook body, facilitating the surgeon to clearly see the surgical site, and effectively improving the safety of the surgery.

[0050] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in the relevant technical fields, shall be equally included in the patent protection scope of the present utility model.
