Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an acupuncture clamp and an acupuncture instrument. Background Art
[0002] As modern Chinese medicine has been conducting more in-depth research on electroacupuncture and electromoxibustion, many studies require different stimulation current directions and magnitudes for different acupoint groups for different diseases, and different degrees of warm stimulation for the main and auxiliary acupoints. Therefore, acupuncture needles are usually used in conjunction with acupuncture instruments. After the acupuncture needles are inserted into the acupoints, the acupuncture instrument is connected to the acupuncture needles through the acupuncture clamps, which clamp the ends of the acupuncture needles and supply power to the acupuncture needles for electrotherapy.
[0003] Existing acupuncture clamps usually use crocodile clamps, but during the clamping operation, the crocodile clamps are difficult to operate and require a lot of force to open, which is inconvenient to operate. At the same time, the clamping stability of the crocodile clamp is relatively poor and it is easy to fall off the acupuncture needle. Therefore, it is necessary to design an acupuncture clamp to facilitate the clamping operation. Utility Model Content
[0004] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide an acupuncture clamp and an acupuncture instrument, which are easy to operate, can quickly clamp acupuncture needles, and are more labor-saving.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: an acupuncture clamp for clamping acupuncture needles, comprising:
[0006] A shell, the shell is non-conductive and defines a cavity with upper and lower openings;
[0007] A clamping needle, the clamping needle is conductive and located in the cavity, the clamping needle can reciprocate along the axial direction of the cavity, one end of the clamping needle is a hook portion, the clamping needle can move downward under the push of an external force, and the hook portion can extend out of the cavity from the opening located below and hook the acupuncture needle;
[0008] A spring, the spring is sleeved outside the clamping needle, the spring always provides a force for the clamping needle to move up and reset, so that the acupuncture needle is clamped between the hook portion and the housing;
[0009] A connecting wire is electrically connected to the other end of the clamping needle.
[0010] The beneficial effects of the utility model are: the acupuncture clamp pushes the clamped needle vertically, and uses the spring to reset and clamp the acupuncture needle. It only needs to apply force in the vertical direction, which is simple to operate and saves effort. The elastic clamping of the acupuncture needle avoids damage to the acupuncture needle and the clamping of the acupuncture needle is stable.
[0011] Furthermore, the clamping needle includes a boss located in the middle position thereof, the upper end of the spring abuts against the boss, the lower end of the spring is fixed to the inner wall of the shell, and the spring is in a continuously compressed state when the clamping needle moves downward.
[0012] Initially, the spring is in a natural state, that is, the hook portion does not extend out of the cavity and does not hook the acupuncture needle. When the clamping needle moves down, the spring continues to compress. When the acupuncture needle is clamped between the shell and the hook portion, the hook portion still moves down a short distance relative to the initial state. At this time, the spring is still in a compressed state, so it still has elastic force to provide a force for clamping the acupuncture needle.
[0013] Furthermore, a limit plate located in the cavity is provided at one end of the shell near the hook portion, the limit plate is fixed to the inner wall of the shell, and the limit plate separates the lower end of the cavity into a protective cavity and a connecting cavity, the hook portion abuts against the limit plate, and the end of the hook portion can be located in the protective cavity. The limit plate limits the upward movement distance of the clamping needle to prevent the clamping needle from moving upward too far under the action of the spring.
[0014] Furthermore, the height position of the lower end of the limit plate is higher than the height position of the lower end of the shell, and when the hook portion abuts against the limit plate, the hook portion is completely located in the cavity. When the acupuncture clamp is not in use, the hook portion will not protrude from the shell, effectively protecting the hook portion.
[0015] Furthermore, the acupuncture clamp further comprises a sliding cover, which is non-conductive, plugged with the clamping needle and moves synchronously, and can slide up and down along the cavity. The sliding cover can be easily pressed to push the clamping needle downward.
[0016] Furthermore, the sliding cover is provided with a convex edge in the circumference, the diameter of the convex edge is larger than the diameter of the upper end of the housing, and the sliding cover can abut against the upper end of the housing when moving downward. The convex edge limits the downward movement distance of the sliding cover.
[0017] Furthermore, the sliding cover comprises a guide portion of a hollow cylindrical structure and a top cover portion located at the top of the guide, a guide protrusion fixed to the shell is provided at the upper end of the cavity, the guide protrusion extends axially along the shell, and a guide groove for the guide protrusion to slide is provided on the outer wall of the guide portion. The guide protrusion and the guide groove cooperate to limit the sliding cover in the circumferential direction to prevent the sliding cover from rotating in the cavity.
[0018] Furthermore, a slot is provided on the inner wall of the guide part, and the clamping needle includes a plug-in portion that can be inserted into the slot. The plug-in portion and the slot are plugged in an interference fit to achieve synchronous movement of the sliding cover and the clamping needle.
[0019] Furthermore, the cavity includes an upper cavity and a lower cavity which are arranged vertically, the diameter of the sliding cover is larger than the diameter of the lower cavity, and the sliding cover can only slide in the upper cavity, which limits the downward movement distance of the sliding cover.
[0020] The utility model also discloses an acupuncture instrument, comprising an acupuncture instrument body and the acupuncture clamp, wherein the connecting line is electrically connected to the acupuncture instrument body. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0029] Example
[0030] See attached Figure 1 and attached Figure 3As shown, the acupuncture clamp of the utility model is used to clamp the needle 2, and includes a shell 1, a clamping needle 2, a spring 3 and a connecting wire 4. The shell 1 is non-conductive, and the shell 1 defines a cavity 11 with upper and lower openings. The clamping needle 2 is conductive and is located in the cavity 11. The clamping needle 2 can move back and forth axially along the cavity 11. One end of the clamping needle 2 is a hook portion 22. The clamping needle 2 can move downward under the push of an external force, so that the hook portion 22 extends out of the cavity 11 from the opening located below and hooks the acupuncture needle 6. The spring 3 is sleeved on the outside of the clamping needle 2, and the spring 3 always provides a force for the clamping needle 2 to move up and reset. The connecting wire 4 is electrically connected to the other end of the clamping needle 2. The up and down direction is also the axial direction of the shell 1.
[0031] Initially, see Appendix Figure 1 As shown, the clamping needle 2 is in the first position, and the acupuncture clamp is not in use. When the acupuncture clamp is in use, the housing 1 is held, which is non-conductive, and the clamping needle 2 is pressed downward. The clamping needle 2 moves downward under the action of external force and extends out of the cavity 11. At this time, the hook portion 22 at the end of the clamping needle 2 hooks the acupuncture needle 6. After the external force is released, the clamping needle 2 quickly moves upward and resets under the action of the spring 3, and the acupuncture needle 6 is clamped between the housing 1 and the hook portion 22, so that the acupuncture needle 6 is fixed. At this time, see the attached Figure 2 As shown, the clamping needle 2 is in the second position. The connecting wire 4 is energized, and the acupuncture needle 6 is powered through the conductive clamping needle 2. The acupuncture clamp in this embodiment vertically pushes the clamping needle 2, and uses the spring 3 to reset and clamp the needle 2. It only needs to apply force in the vertical direction, which is simple to operate and saves effort. The elastic clamping of the acupuncture needle 6 avoids damage to the acupuncture needle 6, and the clamping of the acupuncture needle 6 is stable.
[0032] In one embodiment, see the attached Figure 3 and attached Figure 5 As shown, the clamping needle 2 includes a clamping needle body 21, the lower end of the clamping needle body 21 is connected to a hook portion 22, and the hook portion 22 is an arc structure, including two vertical sections and an arc section located between the two vertical sections. The arc section has the same curvature as the acupuncture needle 6. When the acupuncture needle 6 is clamped between the housing 1 and the hook portion 22, the acupuncture needle 6 will contact the hook portion 22.
[0033] See attached Figure 3As shown, a boss 23 is provided in the middle position of the clamping needle body 21, the upper end of the spring 3 abuts against the boss 23, the lower end of the spring 3 is fixed to the inner wall of the shell 1, and the spring 3 is in a continuously compressed state when the clamping needle 2 moves downward. Initially, the spring 3 is in a natural state, that is, the hook portion 22 does not extend out of the cavity 11, nor does it hook the acupuncture needle 6. When the clamping needle 2 moves downward, the spring 3 is continuously compressed. When the acupuncture needle 6 is clamped between the shell 1 and the hook portion 22, the hook portion 22 still moves down a short distance (the diameter of the acupuncture needle 6) relative to the initial state. At this time, the spring 3 is still in a compressed state, and therefore still has elastic force, providing a force for the clamping needle 2.
[0034] In one embodiment, the clamping needle body 21 is a conductive metal sheet, which is processed and bent to form the hook portion 22 .
[0035] In one embodiment, see the attached Figure 3 As shown, the end of the shell 1 close to the hook portion 22 is provided with a limit plate 12 located in the cavity 11, and the limit plate 12 is fixed to the inner wall of the shell 1. The limit plate 12 separates the lower end of the cavity 11 into a protective cavity and a connecting cavity. The hook portion 22 abuts against the limit plate 12, and the end of the hook portion 22 can be located in the protective cavity. The limit plate 12 limits the upward movement distance of the clamping needle 2 to prevent the clamping needle 2 from moving too far upward under the action of the spring 3. Of course, without the limit plate, the clamping needle 2 can also move up and down.
[0036] See attached Figure 3 As shown, the height position of the lower end of the limiting piece 12 is higher than the height position of the lower end of the housing 1, and when the hook portion 22 abuts against the limiting piece 12, the hook portion 22 is completely located in the cavity 11. That is, when the clamping needle 2 is in the first position, the hook portion 22 will not protrude from the housing 1, effectively protecting the hook portion 22.
[0037] In one embodiment, see the attached Figure 1 As shown, the acupuncture clamp further includes a sliding cover 5, which is non-conductive, plugged with the clamping needle 2 and moves synchronously, and can slide up and down along the cavity 11. The sliding cover 5 is made of insulating material, which is convenient to press to push the clamping needle 2 downward.
[0038] See attached Figure 4 As shown, the circumference of the slide cover 5 is provided with a convex edge 51, the diameter of the convex edge 51 is larger than the diameter of the upper end of the shell 1, and the slide cover 5 can abut against the upper end of the shell 1 when it moves downward. Initially, there is a gap between the convex edge 51 and the shell 1, and when the slide cover 5 and the clamping needle 2 move downward synchronously, the convex edge 51 can abut against the shell 1. The convex edge 51 limits the downward movement distance of the slide cover 5 (that is, the clamping needle 2).
[0039] The slide cover 5 includes a guide portion of a hollow cylindrical structure and a top cover portion located at the top of the guide, and the guide portion and the top cover portion form an insertion cavity with an open lower end for protecting the clamping needle 2. Initially, part of the wire portion is also located in the cavity 11, that is, the slide cover 5 will not be separated from the housing 1 during the up and down movement, and the clamping needle 2 is always protected to prevent the clamping needle 2 from being exposed to the outside.
[0040] See attached Figure 4 As shown, the upper end of the cavity 11 is provided with a guide protrusion 111 fixed to the housing 1, the guide protrusion 111 extends axially along the housing 1, and the outer wall of the guide portion is provided with a guide slot 52 for the guide protrusion 111 to slide. The guide protrusion 111 cooperates with the guide slot 52 to limit the slide cover 5 in the circumferential direction to prevent the slide cover 5 from rotating in the cavity 11.
[0041] A slot 53 is provided on the inner wall of the guide portion, and the clamping needle 2 includes a plug-in portion 24 that can be inserted into the slot 53. The plug-in portion 24 is located at the upper end of the clamping needle body 21, and two plug-in portions 24 are provided, which are symmetrically arranged relative to the axis of the housing 1. The plug-in portion 24 and the slot 53 are plugged in interference fit to achieve synchronous movement of the sliding cover 5 and the clamping needle 2.
[0042] The cavity 11 includes an upper cavity and a lower cavity arranged vertically, the diameter of the slide cover 5 is larger than the diameter of the lower cavity, and the slide cover 5 can only slide in the upper cavity. In this way, the downward movement distance of the slide cover 5 is limited, and when the slide cover 5 moves downward to the junction of the upper cavity and the lower cavity, the slide cover 5 cannot move downward further.
[0043] The connecting wire 4 is an electric wire, and the connecting wire 4 is fixed by welding to the upper end of the clamping needle body 21. A plug is fixed to the end of the connecting wire 4, and a wire hole for the connecting wire 4 to pass through is provided on the sliding cover 5.
[0044] In one embodiment, an acupuncture instrument is disclosed, including an acupuncture instrument body and the acupuncture clamp described above, wherein the connecting line 4 is electrically connected to the acupuncture instrument body, and a plug is inserted into a socket on the acupuncture instrument body.
[0045] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
