Description

Technical Field

[0001] This invention relates to the field of needle knife technology, and in particular to a retractable arc-shaped needle knife. Background Technology

[0002] The needle knife resembles an acupuncture needle in appearance, but its tip has a narrow blade. It is a traditional Chinese medicine medical device developed based on modern Western surgical techniques and traditional Chinese acupuncture. The needle knife differs from both acupuncture and Western surgical methods; it is an organic combination of the two, exerting the dual functions of acupuncture and cutting. By stimulating the flow of Qi and blood, and releasing adhesions and contractures around the lesion, it achieves pain relief.

[0003] Currently, traditional needle knives are all straight, which are effective in treating lesions in subcutaneous tissue and fascia, but cannot be used to treat areas covered by bone tissue and fascia.

[0004] To address this, a retractable arc-shaped needle knife is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a retractable arc-shaped needle knife, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A retractable arc-shaped needle knife includes a flexible needle core and a needle sheath. The flexible needle core includes a needle shaft with an elastically bent portion formed at the lower end of the needle shaft. A needle blade is formed at the lower end of the elastically bent portion. The flexible needle core is slidably inserted into the needle sheath. When the deformation point on the elastically bent portion is located inside the needle sheath, the elastically bent portion is in a vertical state. When the deformation point on the elastically bent portion extends out of the needle sheath, the elastically bent portion is in a bent state.

[0008] In a retractable arc-shaped needle knife according to the present invention, a first handle is fixedly connected to the top of the needle shaft.

[0009] In a retractable arc-shaped needle knife according to the present invention, the surface of the first handle is provided with anti-slip texture.

[0010] In a retractable arc-shaped needle knife according to the present invention, a spring is sleeved on the needle shaft, an annular groove is formed on the top of the needle sheath, the bottom of the spring is fixed in the annular groove, and the top of the spring is fixed to the bottom of the first handle.

[0011] In a retractable arc-shaped needle knife according to the present invention, a second handle is formed at the upper end of the needle sheath.

[0012] In a retractable arc-shaped needle knife according to the present invention, the length of the flexible needle core is 5cm-10cm.

[0013] In a retractable arc-shaped needle knife according to the present invention, the diameter of the flexible needle core is 0.5mm-1mm.

[0014] In a retractable arc-shaped needle knife according to the present invention, the length of the needle blade is 3mm.

[0015] This utility model has at least the following beneficial effects:

[0016] This invention utilizes a flexible needle core and a needle sheath. When in use, after selecting the operating point, hold the first handle and insert the needle vertically. At this time, the deformation point on the elastic bending part is located inside the needle sheath. After reaching the bone or fascia, hold the needle sheath and push the first handle forward to push the deformation point out of the needle sheath, thereby making the elastic bending part bend. This allows for the release of tissues covered by bone or fascia, making the lesion easier to heal. Attached Figure Description

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Please refer to Figures 1 to 4 As shown, this embodiment provides a retractable arc-shaped needle knife, including a flexible needle core and a needle sheath 3. The flexible needle core has a length of 5cm-10cm and a diameter of 0.5mm-1mm. The flexible needle core includes a needle shaft 1. To facilitate holding the needle shaft 1, a first handle 2 is fixedly connected to the top of the needle shaft 1. An elastic bending portion 101 is formed at the lower end of the needle shaft 1. A needle blade 102 is formed at the lower end of the elastic bending portion 101. The length of the needle blade 102 is 3mm. The flexible needle core is slidably inserted into the needle sheath 3. When the deformation point 101 on the elastic bending portion 101... When the needle is inside the needle sheath 3, the elastic bending part 101 is in a vertical state. When the deformation point 1011 on the elastic bending part 101 extends out of the needle sheath 3, the elastic bending part 101 is in a bent state. In order to prevent the deformation point 1011 on the elastic bending part 101 from easily detaching from the needle sheath 3, a spring 4 is sleeved on the needle shaft 1. An annular groove 301 is opened at the top of the needle sheath 3. The bottom of the spring 4 is fixed in the annular groove 301, and the top of the spring 4 is fixed at the bottom of the first handle 2. Under the elastic force of the spring 4, the deformation point 1011 on the elastic bending part 101 is pressed into the needle sheath 3.

[0026] By adopting the above technical solution, when using the device, after selecting the operating point, hold the first handle 2 and insert the needle vertically. At this time, the deformation point 1011 on the elastic bending part 101 is located inside the needle sheath 3. After reaching the bone or fascia area, hold the needle sheath 3 and push the first handle 2 forward to push the deformation point 1011 out of the needle sheath 3, thereby making the elastic bending part 101 bend, which can then loosen the tissues covered by bone or fascia.

[0027] In this embodiment, to prevent slippage when holding the first handle 2, the surface of the first handle 2 is provided with anti-slip texture.

[0028] In this embodiment, a second handle 302 is formed on the upper end of the needle sheath 3 to facilitate holding the needle sheath 3.

[0029] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
