Description

Painless acupuncture and continuous needle insertion instrument Technical Field

[0001] The present invention relates to the technical field of acupuncture, and in particular to a painless and continuous needle insertion instrument for acupuncture. Background Art

[0002] Acupuncture is a therapeutic method in Traditional Chinese Medicine (TCM). It involves acupuncture or moxibustion (using moxa or other medicinal herbs as a warm compress) at specific acupuncture points on the body to regulate the body's qi and blood, thereby achieving the goals of disease treatment, disease prevention, and health care. The process typically includes steps such as acupoint selection, disinfection, needling, manipulation, needle retention, and needle removal. During acupuncture, different needle sizes (generally categorized as 18-gauge, 25-gauge, and 30-gauge, from thin to thick) are selected based on the depth of the acupoint. During acupuncture, the skin is pinched (needle insertion) and the needle is slowly inserted into the skin. Different angles (such as straight, oblique, and shallow insertion) and depths can be used as needed. However, this method has obvious drawbacks: only one needle can be inserted at a time, making continuous needling impossible, which significantly reduces acupuncture efficiency.

[0003] To address this issue, we designed a continuous acupuncture instrument based on the principles of traditional acupuncture therapy to achieve continuous acupuncture. This instrument can provide higher acupuncture efficiency, save valuable acupuncture time, and reduce pain caused by needle insertion. Summary of the Invention

[0004] In response to the problems existing in the above-mentioned prior art, the present invention provides a painless and continuous acupuncture needle insertion instrument with a reasonable structure and practicality. This acupuncture instrument has the advantages of good operating feel and convenient force application, can achieve continuous acupuncture, provide higher acupuncture efficiency, save precious acupuncture time, and reduce the pain caused by needle insertion.

[0005] In order to achieve the above-mentioned object, the present invention adopts a painless and continuous acupuncture needle insertion instrument, which includes the following components:

[0006] A gun body with a muzzle at one end;

[0007] A firing channel extending from the muzzle to the inner cavity of the gun body and having a firing cavity and a striking cavity;

[0008] a loading portion, which is detachably mounted on the firing chamber and provides the firing chamber with acupuncture needles, wherein at least one acupuncture needle is placed in the loading portion and contacts the elastic component so as to provide an elastic force for the acupuncture needle to move toward the firing chamber under the action of the elastic component;

[0009] a slide slidably mounted along the striking cavity and having a firing pin at a front end and a firing and holding mechanism;

[0010] The launching and holding mechanism includes a power element for driving the slide to slide along the striking cavity and causing the striker to strike the acupuncture needle, and a restoring element for providing a restoring force to the slide away from the striking direction.

[0011] This acupuncture instrument has the advantages of good operating feel and convenient force application. It can achieve continuous acupuncture, provide higher acupuncture efficiency, save precious acupuncture time, and reduce the pain caused by needle insertion.

[0012] As a further optimization of the above scheme, the power element includes a needle insertion impact point installed below the firing pin and a first trigger part. The middle part of the first trigger part is a pivotal connection part, one end is installed on the handle part of the gun body and forms a trigger part, and the other end is a impact part. The trigger action of the above trigger part drives the first trigger part to swing with the pivotal connection part as the rotation center. The above needle insertion impact point is located on the rotation path of the above impact part. The above recovery element is a tension spring and provides tension for restoring the position of the impact slide. After the acupuncture needle is installed, the spring presses the needle into the firing chamber, and the impact part impacts the needle insertion impact point and drives the firing pin forward to impact the tail of the acupuncture needle to drive the acupuncture needle into the skin.

[0013] As a further optimization of the above solution, the power element includes a stop retainer pivotally mounted in the impact chamber and stopping the slide, a return spring sleeved on the slide and fixed at one end to the inner wall of the impact chamber, and a second trigger member capable of driving the stop retainer to separate from the slide, wherein:

[0014] After the brake retainer is disengaged from the slide, the slide is pushed by the return spring to move along the striking cavity, causing the striker to collide with the acupuncture needle and knock the acupuncture needle out of the firing cavity. The stop retainer is provided with a blocking block to block the forward movement of the slide, so that at a first rotation angle, the blocking block is fixed to the slide, and at a second rotation angle, the blocking block is disengaged from the slide; wherein:

[0015] The slide has a first blocking groove and a second blocking groove for accommodating a blocking block, so that when the first blocking groove accommodates the blocking block, the recoil spring is compressed and has an elastic force to push the slide toward the firing chamber; when the second blocking groove accommodates the blocking block, the recoil spring is reset and pushes the slide to move along the impact chamber, causing the firing pin to collide with the acupuncture needle and knock the acupuncture needle out of the firing chamber.

[0016] The stop retaining member includes a horizontal portion, a pivot portion and a return spring. The above-mentioned blocking block is installed at one end of the horizontal portion and the side of the blocking block close to the muzzle is inclined so as to facilitate the movement of the blocking block from the second blocking groove to the first blocking groove during the rearward movement of the slide. The pivot portion is installed in the middle of the above-mentioned horizontal portion and the return spring is installed at the other end of the above-mentioned horizontal portion.

[0017] After the acupuncture needle is installed, the spring presses the needle into the firing chamber, and the second trigger member acts as a trigger to drive the blocking block to move from the second blocking groove to the first blocking groove. The return spring resets and pushes the slide to move along the impact cavity, causing the firing pin to collide with the acupuncture needle and knock the acupuncture needle out of the firing chamber to inject the acupuncture needle into the skin. After the acupuncture needle is ejected, the slide is pulled back to reset the slide, and the blocking block moves from the first blocking groove to the second blocking groove, thereby completing the continuous acupuncture needle application by cyclically repeating the above actions.

[0018] As a further optimization of the above-mentioned solution, the first safety piece is hinged to the outside of the gun body, and an embedding opening is provided on the outside of the slide and the embedding opening is located on the rotation path of the above-mentioned first safety piece. When the above-mentioned first safety piece is in the first rotation state, the first safety piece is snapped into the embedding opening; when the above-mentioned first safety piece is in the second rotation state, the first safety piece is disengaged from the embedding opening. When not in use, the first safety piece can be snapped into the embedding opening. By ensuring that the slide cannot move when not in use, the risk of the acupuncture needle falling out due to accidents such as falling during use can be avoided.

[0019] As a further optimization of the above-mentioned scheme, the second safety member is hinged on the gun body and has a contact part located on the retreat path of the slide, a hinged part hinged on the gun body and a movable pawl part. The torsion spring is sleeved on the hinged part and provides a restoring force for the hinged part. The hinged part is provided with a first ratchet groove and a second ratchet groove that are a matching structure with the ratchet part. When the ratchet part is in contact with the first ratchet groove, the slide contacts the contact part and is in a standby state. When the ratchet part is in contact with the second ratchet groove, the slide is disengaged from the contact part and the slide continues to move backward. The design of the second safety member further improves the safety of the acupuncture instrument. When in use, the pawl contacts the first ratchet groove, the slide contacts the contact part and is in a standby state. By ensuring that the slide cannot move when not in use, the risk of the acupuncture needle falling out due to accidents such as falling during use can be avoided.

[0020] As a further optimization of the above-mentioned scheme, the third safety piece is hinged below the second safety piece and is located at the handle portion of the gun body. The third safety piece includes a pressure-bearing part, an elastic element connected between the pressure-bearing part and the gun body, and an extrusion section extending upward along the pressure-bearing part and contacting the pawl part. When the pressure-bearing part is subjected to external pressure, the extrusion section contacts and squeezes the pawl part so that the pawl part enters the second ratchet groove from the first ratchet groove. The design of this structure forms the third safety structure of the present invention, so that the slide can slide only when the acupuncture instrument is in a gripping state, thereby avoiding the risk of the acupuncture needle falling out due to accidents such as falling during use.

[0021] 1. The painless and continuous acupuncture needle insertion device of the present invention has the following beneficial effects:

[0022] 2. The painless and continuous acupuncture instrument of the present invention has the advantages of good operating feel and convenient force application. It can achieve continuous acupuncture, provide higher acupuncture efficiency, save precious acupuncture time, and reduce the pain caused by needle insertion.

[0023] 3. The painless and continuous acupuncture needle insertion instrument of the present invention cleverly designs the power element into a trigger impact structure. After the acupuncture needle is installed, the spring presses the needle into the firing chamber, the impact part hits the needle insertion point and drives the firing pin forward to hit the needle tail of the acupuncture needle, thereby inserting the acupuncture needle into the skin.

[0024] 4. The painless and continuous needle insertion instrument of the present invention designs the power element into a more powerful impact structure. After the acupuncture needle is installed, the spring presses the needle into the firing chamber, and the second trigger member acts as a trigger to drive the blocking block to move from the second blocking groove to the first blocking groove. The return spring resets and pushes the slide to move along the impact chamber and causes the firing pin to collide with the acupuncture needle and knock the acupuncture needle out of the firing chamber and then penetrate the skin, greatly improving the acupuncture needle insertion effect.

[0025] The painless and continuous needle insertion instrument of the present invention is cleverly designed with a three-safety structure to minimize the risk of the acupuncture needles being dislodged due to accidents such as the slide falling when not in use.

[0026] With reference to the following description and drawings, specific embodiments of the present invention are disclosed in detail, indicating how the principles of the present invention can be adopted. It should be understood that the scope of the embodiments of the present invention is not limited thereby, and the embodiments of the present invention include many changes, modifications and equivalents.

[0041] Please refer to Figures 1 and 2 of the specification. The present invention provides a first embodiment of a painless, continuous needle insertion instrument for acupuncture. In this embodiment, the acupuncture instrument includes the following components:

[0042] A gun body 1 having a muzzle at one end. In this example, whether the gun body 1 has a handle is not limited. The handle portion 11 in FIG2 of the specification is only for illustration. This embodiment only limits the gun body 1 to having the following firing channel 2;

[0043] A firing channel 2, which extends from the muzzle to the inner cavity of the gun body 1 and has a firing chamber 21 and a striking chamber 22. Preferably, in this example, the firing chamber 21 and the striking chamber 22 form a stepped structure;

[0044] A loading portion 3, which is detachably mounted on the firing chamber 21 and provides an acupuncture needle 31 for the firing chamber 21. At least one acupuncture needle 31 is placed in the loading portion 3 and contacts an elastic component 32, so that the elastic component 32 provides an elastic force for the acupuncture needle 31 to move toward the firing chamber 21.

[0045] We also provide an acupuncture clamp, which is loaded into the loading section (3) before use. A schematic model of this clamp is shown in Figure 10 . Specifically, the clamp is a sealed rectangular structure with acupuncture needles glued together side by side, with the tails glued to the top of the clamp to secure them. The front and back of the rectangular structure are made of paper. After disinfection, the clamp is ready for use. To use, the paper structures are torn off and the loading section (3) is inserted, allowing for continuous needle insertion.

[0046] a carriage 4 slidably mounted along the striking cavity 22 and having a firing pin 41 at the front end and a firing and holding mechanism 5 ;

[0047] The launching and holding mechanism 5 includes a power element 6 that drives the slide 4 to slide along the striking cavity 22 and causes the striker 41 to strike the acupuncture needle 31 , and a restoring element 7 that provides a restoring force to the slide 4 away from the striking direction.

[0048] This acupuncture instrument has the advantages of good operating feel and convenient force application. It can achieve continuous acupuncture, provide higher acupuncture efficiency, save precious acupuncture time, and reduce the pain caused by needle insertion.

[0049] In this embodiment, the power element 6 includes a needle insertion impact point 411 installed below the firing pin 41 and a first trigger member 61. The middle part of the first trigger member 61 is a pivot connection part 611, one end is installed on the handle part 11 of the gun body 1 and forms a trigger part 612, and the other end is a impact part 613. The trigger action of the above-mentioned trigger part 612 drives the first trigger member 61 to swing with the pivot connection part 611 as the rotation center. The above-mentioned needle insertion impact point 411 is located on the rotation path of the above-mentioned impact part 613. The above-mentioned recovery element 7 is a tension spring and provides tension for the position recovery of the impact slide 4, so that after the acupuncture needle 31 is installed, the spring presses the needle into the firing chamber 21, and the impact part 613 impacts the needle insertion impact point 411 and drives the firing pin 41 to move forward to impact the needle tail of the acupuncture needle 31, so as to drive the acupuncture needle 31 into the skin.

[0050] Referring to Figures 3-5 of the specification, the present invention provides a second embodiment of a painless, continuous needle insertion instrument. In this second embodiment, the impact mode of the acupuncture needle 31 is changed from a driven impact to an elastic impact to enhance the acupuncture force and effect. Specifically, the acupuncture instrument in this embodiment includes the following components:

[0051] a gun body 1 having a muzzle at one end;

[0052] A firing channel 2, which extends from the muzzle to the inner cavity of the gun body 1 and has a firing cavity 21 and a striking cavity 22;

[0053] A loading portion 3, which is detachably mounted on the firing chamber 21 and provides an acupuncture needle 31 for the firing chamber 21. At least one acupuncture needle 31 is placed in the loading portion 3 and contacts an elastic component 32, so that the elastic component 32 provides an elastic force for the acupuncture needle 31 to move toward the firing chamber 21.

[0054] a carriage 4 slidably mounted along the striking cavity 22 and having a firing pin 41 at the front end and a firing and holding mechanism 5 ;

[0055] The launching and holding mechanism 5 includes a power element 6 that drives the slide 4 to slide along the striking cavity 22 and causes the striker 41 to strike the acupuncture needle 31 , and a restoring element 7 that provides a restoring force to the slide 4 away from the striking direction.

[0056] The power element 6 includes a stop retainer 62 pivotally mounted in the striking cavity 22 and stopping the slide 4, a return spring 63 sleeved on the slide 4 and fixed at one end to the inner wall of the striking cavity 22, and a second trigger member 64 capable of driving the stop retainer 62 to separate from the slide 4, wherein:

[0057] After the brake retainer is separated from the slide 4, the slide 4 is pushed by the return spring 63 to move along the impact cavity 22, causing the firing pin 41 to collide with the acupuncture needle 31 and knock the acupuncture needle 31 out of the firing cavity 21. The stop retainer 62 is provided with a blocking block 621 to block the forward movement of the slide 4, so that at a first rotation angle, the blocking block 621 is fixed to the slide 4, and at a second rotation angle, the blocking block 621 is separated from the slide 4; wherein:

[0058] The slide 4 has a first blocking groove 42 and a second blocking groove 43 for accommodating the blocking block 621, so that when the first blocking groove 42 accommodates the blocking block 621, the recoil spring is compressed and has an elastic force to push the slide 4 to move toward the launching chamber 21; when the second blocking groove 43 accommodates the blocking block 621, the recoil spring is reset and pushes the slide 4 to move along the impact chamber 22 and causes the firing pin 41 to collide with the acupuncture needle 31 and knock the acupuncture needle 31 out of the launching chamber 21.

[0059] The stop retaining member 62 includes a horizontal portion 622, a pivot portion 623 and a return spring 624. The above-mentioned blocking block 621 is installed at one end of the horizontal portion 622 and the side of the blocking block 621 close to the muzzle is inclined so that the blocking block 621 can be moved from the second blocking groove 43 to the first blocking groove 42 during the rearward movement of the slide 4. The pivot portion 623 is installed in the middle of the above-mentioned horizontal portion 622 and the return spring 624 is installed at the other end of the above-mentioned horizontal portion 622.

[0060] After the acupuncture needle 31 is installed, the spring presses the needle into the firing chamber 21, and the second trigger member 64 acts as a trigger to drive the blocking block 621 to move from the second blocking groove 43 to the first blocking groove 42. The return spring resets and pushes the slide 4 to move along the impact chamber 22 and causes the firing pin 41 to collide with the acupuncture needle 31 and knock the acupuncture needle 31 out of the firing chamber 21 to inject the acupuncture needle 31 into the skin. After the acupuncture needle 31 is ejected, the slide 4 is pulled back to reset the slide 4, and the blocking block 621 moves from the first blocking groove 42 to the second blocking groove 43, thereby completing the continuous acupuncture of the acupuncture needle 31 by cycling the above actions.

[0061] In this embodiment, the restoring element 7 is designed as a motorized component, such as a motorized telescopic rod. Once the carriage 4 has moved outward, the motorized telescopic rod automatically returns the carriage 4 to its original position, enabling continuous acupuncture. This means that once the carriage 4 has completed its movement, the motorized telescopic rod automatically returns the carriage 4 to its original position, allowing for the next acupuncture session without manual intervention.

[0062] Please refer to Figures 6 and 7 of the specification. The present invention provides a third embodiment of a painless and continuous needle insertion instrument for acupuncture. In this embodiment, the acupuncture instrument includes the following components:

The third safety member 94 includes a pressure-bearing portion 941, an elastic element 942 connected between the pressure-bearing portion 941 and the gun body 1, and an extrusion section 943 extending upward along the pressure-bearing portion 941 and contacting the pawl portion 93. When the pressure-bearing portion 941 is subjected to external pressure, the extrusion section 943 contacts and squeezes the pawl portion 93 so that the pawl portion 93 enters the second ratchet groove 923 from the first ratchet groove 922. The design of this structure forms the third safety structure of the present invention, so that the slide 4 can slide only when the acupuncture instrument is in a gripping state, thereby avoiding the risk of the acupuncture needle 31 falling out due to accidents such as falling during use.

[0086] In summary, this acupuncture instrument has the advantages of good operating feel and convenient force application, can achieve continuous acupuncture, provide higher acupuncture efficiency, save precious acupuncture time, and reduce the pain caused by needle insertion.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
