Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0031] See also Figures 1 to 2As shown, the present application also provides a limb nerve puncture positioning device, including at least two straps 100, a positioning column 200 and a fixing assembly 300, wherein two adjacent straps 100 are hinged, and the positioning column 200 is slidably arranged on each of the straps 100, and a positioning hole 210 is provided in the positioning column 200, and the positioning hole 210 is used for allowing the puncture needle to pass through the nerve position of the positioning limb, and the fixing assembly 300 is provided on the positioning column 200, and the fixing assembly 300 is used to fix the positioning column 200 on the limb.

[0032] Specifically, the location of the limb nerve refers to the location of the patient's scalp nerve puncture point. The number of straps 100 can be set according to actual needs, with at least two straps 100, and three, four, five, or six straps 100 are also possible. Since the location of the limb nerves is not necessarily in a straight line, the use of two hinged straps 100 facilitates changing the sliding direction of the positioning posts 200 on the two straps 100, facilitating fine-tuning of the limb nerve location. The positioning holes 210 of the positioning posts 200 are used to pass through the puncture needle. When the positioning posts 200 are moved to the corresponding limb nerve location, the position of the positioning holes 210 effectively marks the location of the limb nerve. This not only eliminates the need for additional marking but also greatly enhances ease of use. The fixing assembly 300 is used to secure the positioning posts 200 to the limb, preventing it from shaking. Furthermore, this device can also be used in medical teaching. For example, by attaching the device to a medical mannequin head, the device can be used to locate the scalp nerves on the mannequin head, making it more intuitive and easier for beginners to use, facilitating teaching.

[0033] It should be noted that the diameter of the positioning hole 210 on the positioning post 200 is adapted to the diameter of the puncture needle, or is larger than the diameter of the puncture needle, so as to facilitate the passage of the puncture needle.

[0034] See also Figure 1 As shown, in another embodiment of the present application, the number of the straps 100 is six.

[0035] Specifically, since a complete scalp nerve block involves six scalp nerve puncture points, the number of bandages 100 is set to six. The six scalp nerve puncture points include:

[0036] The supraorbital nerve is a terminal branch of the ophthalmic nerve, the first branch of the trigeminal nerve. It can be touched in the medial 1 / 3 of the supraorbital ridge, just above the midpoint of the pupil. It is mainly responsible for the sensation of part of the forehead.

[0037] The supratrochlear nerve is located about 1 cm inward from the puncture point of the supraorbital nerve. It is responsible for the sensation of the inner forehead, the root of the nose, and part of the inner eyelid area.

[0038] The auriculotemporal nerve, located 1 cm cephalad at the level of the tragus, is responsible for providing sensation to the temporal region (temple area) and part of the external auditory canal.

[0039] The zygomaticotemporal nerve is located in the groove along the zygomatic arch just outside the lateral canthus of the eye and is responsible for providing sensory information to a part of the temporal region (temple area).

[0040] The greater occipital nerve, located midway between the occipital protuberance and mastoid process, is responsible for sensation in the back of the scalp, upper neck, and part of the area behind the ear.

[0041] The lesser occipital nerve, located 2.5 cm outside the injection point of the greater occipital nerve block, is responsible for scalp sensation, which is different from the area covered by the greater occipital nerve.

[0042] During the use of the above-mentioned device, after adjusting the position of the positioning column 200 on the strap 100, the positioning column 200 is fixed using the fixing assembly 300, and the positioning hole 210 of the positioning column 200 is aligned with the position of the above-mentioned scalp nerve, the corresponding anesthetic is injected using the puncture needle to complete the blockade of the scalp nerve, which is beneficial to reduce postoperative pain and improve the efficiency of scalp nerve puncture.

[0043] See also Figure 1 and Figure 2 As shown, in another embodiment of the present application, a slide groove 110 is provided on the strap 100, and the slide groove 110 is slidably connected to the positioning column 200. A first chassis 220 is provided on the positioning column 200, and the first chassis 220 is below the strap 100. A second chassis 230 is provided on the positioning column 200, and the second chassis 230 is located above the strap 100, wherein a first distance is set between the positioning column 200 and the second chassis 230.

[0044] Specifically, a slide groove 110 is provided on the strap 100, and the slide groove 110 is slidably connected to the positioning column 200. A second chassis 230 is provided above the positioning column 200, and a first chassis 220 is provided below the positioning column 200, so that the positioning column 200 is simultaneously limited on the slide groove 110 of the strap 100 by the first chassis 220 and the second chassis 230, and is not easy to detach from the strap 100.

[0045] See also Figure 1 and Figure 2 As shown, in another embodiment of the present application, the shape of the slide groove 110 is square, and the positioning column 200 includes a contact portion for sliding on the slide groove 110, and the shape of the contact portion is square, and the contact portion is adapted to the slide groove 110.

[0046] Specifically, the shape of the slide groove 110 is square, and the contact portion where the positioning column 200 slides with the slide groove 110 is also square, so that the inner walls on both sides of the contact portion of the positioning column 200 abut against the inner walls on both sides of the slide groove 110. The positioning column 200 is further limited by the slide groove 110 and can only slide along the slide groove 110. It is not easy to rotate, thereby improving the stability of the positioning column 200.

[0047] In another embodiment of the present application, a first gap is provided between the first chassis 220 and the strap 100 , and a second gap is provided between the second chassis 230 and the strap 100 .

[0048] Specifically, if Figure 1 and Figure 2 As shown, the first chassis 220 is located below the strap 100, and the second chassis 230 is located above the strap 100. A first gap is provided between the first chassis 220 and the strap 100 to reduce friction between the first chassis 220 and the bottom surface of the strap 100. A second gap is provided between the second chassis 230 and the top surface of the strap 100 to reduce friction between the second chassis 230 and the top surface of the strap 100, allowing the positioning post 200 to slide smoothly on the slide groove 110 of the strap 100. More specifically, the first gap is 1-3 mm, and the second gap is 1-3 mm.

[0049] See also Figure 2 As shown, in another embodiment of the present application, a hemostatic pad 240 is provided on the first chassis 220, and the hemostatic pad 240 is used to fit the nerve position of the limb.

[0050] Specifically, the hemostatic pad 240 is attached to the underside of the first chassis 220, facing the patient's limb nerves. Once the user selects the corresponding scalp nerve location, they puncture the scalp nerve with a puncture needle. After removal, the hemostatic pad 240 comes into direct contact with the scalp nerve, providing a certain degree of hemostasis. More specifically, the hemostatic pad 240 is self-adhesive, with a slightly sticky substance on one side, allowing it to be directly fixed to the first chassis 220, reducing costs.

[0051] See also Figure 1 As shown, in another embodiment of the present application, the shape of the first chassis 220 is any one of a circle, a square, a pentagon, and a hexagon, and the shape of the second chassis 230 is any one of a circle, a square, a pentagon, and a hexagon.

[0052] Specifically, the shapes of the first chassis 220 and the second chassis 230 can be set according to actual needs, such as circular, square, pentagonal, hexagonal, etc. In the present application, the first chassis 220 and the second chassis 230 are both circular and have the same diameter, which is beneficial to aesthetics.

[0053] See also Figure 1 and Figure 2 As shown, in another embodiment of the present application, the fixing assembly 300 includes a first adhesive sticker 310 and a second adhesive sticker 320. The first adhesive sticker 310 is arranged on the first chassis 220, and the first adhesive sticker 310 is provided with a first adhesive portion 311. The second adhesive sticker 320 is arranged on the first chassis 220 and is opposite to the position of the first adhesive sticker 310. The second adhesive sticker 320 is provided with a second adhesive portion 321.

[0054] Specifically, the first adhesive patch 310 is disposed on one side of the first chassis 220, and the second adhesive patch 320 is disposed on the other side of the first chassis 220. The relative positioning of the first adhesive patch 310 and the second adhesive patch 320 not only improves aesthetics, but also allows the first adhesive portion 311 of the first adhesive patch 310 and the second adhesive portion 321 of the second adhesive patch 320 to be adhered to the patient's scalp nerves, thereby facilitating the fixation of the positioning post 200. More specifically, the first adhesive patch 310 is disposed in a cross-intersection with the strap 100, i.e., at a 90-degree angle with the strap 100, and the second adhesive patch 320 is disposed in a cross-intersection with the strap 100, i.e., at a 90-degree angle with the strap 100, thereby enhancing the use of the first adhesive patch 310 and the second adhesive patch 320.

[0055] See also Figure 2 As shown, in another embodiment of the present application, a first easy-tear paper is provided on the first adhesive portion 311 , and a second easy-tear paper is provided on the second adhesive portion 321 .

[0056] Specifically, the first easy-tear paper is used to stick to the first sticking portion 311 , and the second easy-tear paper is used to stick to the second sticking portion 321 , so as to prevent the first sticking portion 311 and the second sticking portion 321 from being exposed and affecting the stickiness.

[0057] See also Figure 1 and Figure 2 As shown, in another embodiment of the present application, two adjacent straps 100 are each provided with a connecting portion 120 at one end close to each other, and hinged columns 130 are provided on the two connecting portions 120 .

[0058] Specifically, there are six straps 100, the leftmost strap 100 has a connection portion 120 only on the right side, the rightmost strap 100 has a connection portion 120 only on the left side, and the remaining four middle straps 100 have connection portions 120 on both sides. This arrangement is conducive to reducing the number of connection portions 120, thereby reducing costs. The hinge column 130 passes through the corresponding connection portion 120 to achieve the hinge between two adjacent straps 100.

[0059] In summary, the present invention provides a limb nerve puncture positioning device, which is provided by setting multiple straps, wherein two adjacent straps are hinged, and a positioning column is slidably provided on each strap, and the positioning hole on the positioning column is used for the puncture needle to pass through. By moving the positioning column on the strap to the position of the patient's limb nerve, it is convenient to mark the position of the patient's limb nerve through the positioning hole, so that the user can fine-tune the position of the patient's limb nerve to adapt to patients with different limbs; the positioning column is then fixed by the first adhesive tape and the second adhesive tape to prevent the positioning column from shaking; in addition, the present device can also be used in medical teaching, for example, the present device is fixed on a medical model head, and by positioning the position of the scalp nerve of the model head by the present device, it is more intuitive and easy for beginners to use, which is conducive to teaching use; the hemostatic pad provided can also achieve a certain degree of hemostasis after puncture by the puncture needle.
