Description

Technical Field

[0001] The utility model belongs to a medical appliance, in particular to an acupuncture needle. Background Art

[0002] Acupuncture is one of the commonly used treatment methods in traditional Chinese medicine and is widely used in clinical practice. Acupuncture treatment involves inserting acupuncture needles into different acupuncture points of the patient, stimulating the surrounding tissues by twisting and lifting the needles, triggering body reactions and achieving therapeutic effects. The predecessors of traditional Chinese medicine used acupuncture to maintain health and treat diseases a long time ago. Until now, acupuncture still plays an indispensable role in medical technology and is trusted by the general public.

[0003] The traditional acupuncture needles widely used at present are all slender stainless steel needle bodies with a certain degree of elasticity. Traditional acupuncture needles are an integrated structure and can usually be divided into three parts: the needle tip, the needle body, and the needle handle.

[0004] When using acupuncture needles for treatment, the needles are inserted into the patient's body at a certain angle, and the longer needle handles are left outside the body. At this time, if the needle handle is hit by external force, it is easy to bend, fall off, or even break the needle, causing secondary damage to the patient. During acupuncture treatment, the needle retention time is usually relatively long. If the weather is relatively cool, the acupuncture site is easily invaded by wind, cold and dampness, which is not conducive to physical recovery, and even symptoms recur. Therefore, when doing acupuncture treatment in cooler weather, the acupuncture site usually needs to be covered with a quilt to keep warm, but because the needle handle is long, directly covering the quilt will inevitably hit the acupuncture needle. Therefore, a bracket must be placed on the acupuncture site before covering the quilt. The patient's acupuncture site needs to remain motionless for a long time under the bracket, because it is easy to touch the bracket if it moves at will, causing the bracket to move, which is likely to cause secondary damage to the patient. At the same time, it is also very inconvenient to put different brackets first and then cover the quilt; the patient's acupuncture site remains motionless under the bracket for a long time, which will also make the patient feel very uncomfortable. Utility Model Content

[0005] In view of the shortcomings of traditional acupuncture needles, the utility model adopts a method of separating the needle handle from the needle body. When the needle needs to be left in the body during acupuncture treatment, if a quilt needs to be covered for warmth, the needle handle can be removed, the needle body can be left in the body, and then the quilt can be directly covered without placing a bracket to protect the acupuncture site first.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An acupuncture needle with a detachable needle handle and needle body comprises a needle handle and a needle body. The needle handle is composed of a connecting rod cap, a connecting rod, a spring, a needle handle tube, and a two-piece clamp; the needle body can be divided into four parts: a needle body head, a limiting plate, a needle body, and a needle tip.

[0008] The needle handle is composed of a connecting rod cap, a connecting rod, a spring, a needle handle tube, and a two-piece chuck. The hemispherical connecting rod cap, the connecting rod, and the two-piece chuck are combined into a whole. The needle handle tube is sleeved on the outside of the connecting rod. There are grooves of appropriate depth on both sides of the inner wall of the needle handle tube. There are convex strips on both sides of the connecting rod. The size and shape of the connecting rod match the size and shape of the inner cavity of the needle handle tube. The convex strips on both sides of the connecting rod are inserted into the grooves on both sides of the inner wall of the needle handle tube. This structure allows the connecting rod to move up and down in the needle handle tube, but cannot rotate left and right. That is, when the needle handle tube is pinched and twisted, the needle handle tube will drive the connecting rod to rotate together. The spring is stuck between the connecting rod cap and the needle handle tube and is in a certain degree of compression. Therefore, the spring supports the connecting rod cap and drives the connecting rod and the two-piece chuck to move upward. The two-piece chuck is closed under the action of the spring and the needle handle tube, and a part of it is pulled into the needle handle tube, so that the two-piece chuck is in a clamping state. Press the connecting rod cap by hand, and the connecting rod pushes the two-piece chuck downward to extend out of the needle handle tube. Without the restraint of the needle handle tube, the two-piece chuck returns to its natural state and opens, entering a released state. The gap at the clamping mouth of the two-piece chuck is small, and the internal cavity gradually increases slightly upward. The strength of the spring is slightly stronger, so that when pinching the needle handle tube to pull out the acupuncture needle normally, the two-piece chuck will not move out of the needle handle tube. It is necessary to press the connecting rod cap by hand to move the two-piece chuck out of the needle handle tube.

[0009] The needle body can be divided into four parts: needle head, limit plate, needle body and needle tip. The lower end of the needle body is the needle tip. The upper end of the needle body is the needle head. The length of the needle head is as short as possible, as long as the two-lobed chuck can hold it securely and will not fall off during acupuncture. The upper part of the needle head is slightly larger, the lower part is slightly smaller, and there are convex strips on both sides. The size and shape of the needle head match the size and shape of the internal cavity of the two-lobed chuck. When the two-lobed chuck clamps the needle head, since the upper part of the needle head is larger than the lower part, during acupuncture, whether it is inserted or pulled out, the needle head will not slip out of the two-lobed chuck of the needle handle; there are convex strips on both sides of the needle head, which are stuck in the gap between the two claws of the two-lobed chuck. When the needle handle tube is pinched and twisted, this structure can ensure that the needle body must also rotate with it.

[0010] There is a limit plate at the joint between the needle head and the needle body, the diameter of the limit plate is 2-3 mm, and the limit plate can prevent the needle body from sinking into the human body. The length of the needle body is determined according to the depth required for acupuncture in different parts of the body.

[0011] The advantages and beneficial effects of the utility model are:

[0012] When performing acupuncture, you can directly cover the exposed acupuncture area with a quilt of appropriate thickness to avoid the invasion of wind, cold and dampness. At the same time, it can also increase the patient's comfort during acupuncture. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1 As shown, an acupuncture needle with a detachable needle handle and needle body comprises a needle handle and a needle body. The needle handle is composed of a connecting rod cap 1, a spring 2, a connecting rod 4, a needle handle tube 3, and a two-piece clamp 5. The needle body can be divided into four parts: a needle head 6, a limit plate 7, a needle body 8, and a needle tip 9.

[0019] The needle handle is composed of a connecting rod cap 1, a connecting rod 4, a spring 2, a needle handle tube 3, and a two-piece chuck 5. The hemispherical connecting rod cap 1, the connecting rod 4, and the two-piece chuck 5 form a whole, and the needle handle tube 3 is sleeved on the outside of the connecting rod 4. Figure 4 As shown, there are grooves of appropriate depth on both sides of the inner wall of the needle handle tube 3, and there are convex strips on both sides of the connecting rod 4. The size and shape of the connecting rod 4 match the size and shape of the internal cavity of the needle handle tube 3. The convex strips on both sides of the connecting rod 4 are inserted into the grooves on both sides of the inner wall of the needle handle tube 3. This structure allows the connecting rod 4 to move up and down in the needle handle tube 3, but cannot rotate left and right, that is, when the needle handle tube 3 is pinched and twisted, the needle handle tube 3 will drive the connecting rod 4 to rotate together. The spring 2 is stuck between the connecting rod cap 1 and the needle handle tube 3 and is in a certain degree of compression. Therefore, the spring 2 pushes against the connecting rod cap to drive the connecting rod 4 and the two-piece clamp 5 to move upward. The two-piece clamp 5 is closed under the action of the spring 2 and the needle handle tube 3, and part of it enters the needle handle tube 3 and is in a clamping state (such as Figure 2 As shown). Press the connecting rod cap 1 by hand to make the connecting rod 4 move downward, and the two-piece clamp 5 also extends downward from the needle handle tube 3. Without the constraint of the needle handle tube 3, the two-piece clamp 5 returns to its natural state and opens, entering the release state. Figure 1 As shown, the gap at the clamping opening of the two-piece clamp 5 is small, and the internal cavity gradually increases slightly upward. The strength of the spring 2 is slightly strong, so that when the needle handle tube 3 is pinched to normally pull out the acupuncture needle, the two-piece clamp 5 will not move out of the needle handle tube 3. It is necessary to press the connecting rod cap 1 by hand to move the two-piece clamp 5 out of the needle handle tube 3 and open the two jaws.

[0020] like Figure 3As shown, the needle body can be divided into four parts: needle head 6, limit plate 7, needle body 8, and needle tip 9. The lower end of the needle body is the needle tip 9. The upper end of the needle body is the needle head 6. The length of the needle head 6 is as short as possible, as long as the two-piece clamp 5 can be clamped securely and will not fall off during acupuncture operation. The length is about 2 mm. Figure 1 and Figure 3 As shown, the upper part of the needle body head 6 is slightly larger, the lower part is slightly smaller, and there are convex strip structures on both sides. The size and shape of the needle body head 6 match the size and shape of the internal cavity of the two-piece clamp 5. When the two-piece clamp 5 clamps the needle body head 6, since the needle body head 6 is larger at the top and smaller at the bottom, during acupuncture, whether inserted or pulled out, the needle body head 6 will not slip out of the two-piece clamp 5; there are convex strip structures on both sides of the needle body head 6, which are stuck in the gap between the two claws of the two-piece clamp 5. When the needle handle tube 3 is pinched and twisted, this structure can ensure that the needle body must also rotate with it.

[0021] There is a limit plate 7 at the joint of the needle head 6 and the needle body 8, and the limit plate 7 has a diameter of 2-3 mm, which can prevent the needle body from sinking into the human body. The length of the needle body is determined according to the depth required for acupuncture treatment in different parts of the body.

[0022] In the specific implementation, the connecting rod and the two-piece chuck are an integrated structure, the appropriate length of the connecting rod head is made into a screw, and a screw hole matching the connecting rod head screw is made in the center of the plane of the hemispherical connecting rod cap. In order to increase reliability, the connecting rod cap can be made into a spherical shape, so that the depth of the screw hole of the connecting rod cap can be made deeper, and the length of the screw of the connecting rod head screwed into the screw hole of the connecting rod cap is longer, thereby improving reliability. During installation, the connecting rod is passed through the needle handle tube, and then the spring is put on. The spring is longer than the length of the connecting rod extending out of the needle handle tube. The spring needs to be compressed to a certain extent before the screw of the connecting rod head can be screwed into the connecting rod cap. In order to further increase reliability, the screw of the connecting rod head can be first stained with an appropriate amount of glue that can bond stainless steel and other metals. After the glue solidifies, it can better prevent the connecting rod cap from falling off during use. In this way, after the needle handle is installed, when there is no external force, the spring is in a certain degree of compression state, the spring supports the connecting rod cap, pulls the connecting rod upward, and the two-piece chuck enters the needle handle tube and is in a clamping state.

[0023] When performing acupuncture, first press the connecting rod cap with your hand to make the two-lobed chuck extend out of the needle handle tube, and the claws of the two-lobed chuck open; then put the needle body head into the cavity of the two-lobed chuck, and release the connecting rod cap, so that the two-lobed chuck clamps the needle body head, the needle handle and the needle body form a whole, and acupuncture operations such as lifting, inserting, and twisting can be performed normally. After lifting, inserting, and twisting, when the needle needs to be retained, press the connecting rod cap with your hand to make the two-lobed chuck in a released state, and then you can take away the needle handle and release the connecting rod cap, so that the needle body remains in the body and only the needle body head remains outside the body. Since the needle body head is very short, directly covering it with a quilt will not have an adverse effect on acupuncture, and even if the acupuncture site moves to a certain extent, it will not cause adverse effects. After acupuncture is completed, you only need to take the quilt upwards (avoid dragging the quilt in a direction parallel to the skin surface). Therefore, using the acupuncture needle can not only avoid the invasion of wind, cold and dampness, but also increase the comfort of the patient during acupuncture.

[0024] It should be noted that, for the convenience of description, the direction of the needle tip is defined as "downward" and the direction of the connecting rod cap is defined as "upward".

[0025] It should be noted that the convex strips on both sides of the connecting rod do not need to extend out of the needle handle tube, that is, at the upper part of the needle handle tube, the part of the connecting rod extending out of the needle handle tube is cylindrical and has no convex strips, so as not to affect the operation of the spring; at the lower part of the needle handle tube, the convex strips end above the joint between the connecting rod and the two-piece chuck, and are not connected to the two-piece chuck, so as to avoid affecting the operation of the two-piece chuck (or it can also be extended to the beginning of the gap between the two claws of the two-piece chuck).

[0026] It should be noted that the gap between the two jaws of the two-piece chuck is slightly wider, which can ensure that when clamping the needle head, after the convex strip of the needle head is stuck in the gap between the jaws, the two-piece chuck can also clamp the needle head securely, and its clamping ability is not affected.
