Description

Technical Field

[0001] This invention relates to the field of acupuncture needle insertion auxiliary devices, specifically an auxiliary positioning needle insertion device for acupuncture. Background Technology

[0002] Acupuncture, an important component of traditional Chinese medicine, regulates Qi and blood and treats diseases by inserting filiform needles into specific acupoints on the body. It is widely used in clinical medicine and preventative healthcare. With the development of medical technology, various acupuncture auxiliary devices have emerged, aiming to reduce the difficulty of acupuncture operations and improve the accuracy and safety of needle insertion, making them especially suitable for beginners and primary healthcare institutions. Currently, acupuncture auxiliary devices on the market are mainly divided into two categories: acupoint location devices and needle insertion assistance devices, respectively addressing the problems of inaccurate acupoint identification and hand tremors during needle insertion. Chinese patent CN116251019B discloses an acupuncture positioning device, which mainly includes a base ring, a vertical frame, an arc-shaped beam, a needle cylinder slidably mounted on the arc-shaped beam, and a rotating ball rotatably connected to the base ring. The needle cylinder is fixedly connected to the rotating ball via a connecting rod. The needle cylinder contains a movable cylinder that can move up and down and a needle clamping mechanism. The rotating ball has a needle groove and a disinfectant spraying mechanism. This device allows for arbitrary adjustment of the needle insertion angle through the sliding of the needle cylinder on the arc-shaped beam and the rotation of the rotating ball. The needle clamping mechanism stably fixes the acupuncture needle for precise insertion. Simultaneously, it can spray disinfectant on the needle tip before insertion, thus improving the stability and safety of acupuncture operations to a certain extent and reducing reliance on the doctor's experience.

[0003] However, the existing technology and the aforementioned comparative patent still have obvious defects: First, the acupuncture needles currently used in clinical practice are all disposable products. They are sealed in sterile storage bags using ethylene oxide or radiation sterilization technology at the factory. They can be directly unsealed and taken out when needed without additional sterilization. In contrast, the local spraying disinfection method used in the comparative patent not only has a limited disinfection range and unstable effect, but also easily leaves residual disinfectant that irritates the patient's skin and affects the efficacy of acupuncture. Second, the overall structure of the device in the comparative patent is complex and large, making it inflexible to carry and use. It is difficult to adapt to different positions on the human body, and when needles need to be retained during acupuncture treatment, the device cannot be quickly separated from the acupuncture needle. The needle clamping mechanism must be loosened before the device can be removed, which seriously affects the efficiency of clinical operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an auxiliary positioning and needle insertion device for acupuncture, which has the functions of quickly clamping and releasing acupuncture needles, accurately positioning and inserting needles, and facilitating quick separation when needles are retained, thus solving the problems mentioned in the background art.

The push tube is slidably installed inside the straight cylinder, the clamping rod is slidably installed inside the push tube, and the control rod is installed inside the push tube and is drively connected to the clamping rod. When the control rod moves relative to the push tube, all the clamping rods move away from each other to release the clamping of the acupuncture needle handle. The auxiliary positioning assembly includes a sliding positioning frame, a connecting rod, and an abutment ring. The sliding positioning frame is slidably installed on the outer wall of the straight cylinder, and the abutment ring is fixedly connected to the sliding positioning frame via the connecting rod.

[0006] Preferably, a circular baffle is fixedly installed at one end of the push tube. The circular baffle has sliding holes arranged in a ring array. The length direction of the sliding holes coincides with the radial direction of the circular baffle. The clamping rod is slidably installed inside the sliding holes, and a clamping pad is fixedly installed on the clamping rod.

[0007] Preferably, the needle-clamping and advancing assembly further includes a turntable and a rotating rod.

The rotating rods and push rods are arranged in a one-to-one correspondence, and one end of the rotating rod is rotatably connected to the corresponding push rod, while the other end of the rotating rod is rotatably connected to the corresponding clamping rod.

[0008] Preferably, a fixing rod is fixedly installed on the circular baffle, a pull rod is fixedly installed on the turntable, and the needle-clamping and pushing assembly further includes a tension spring, the two ends of which are respectively connected to the fixing rod and the pull rod.

[0009] Preferably, a guide hole is provided on one side of the straight tube, and a first slider is fixedly installed on the outside of the end of the push tube away from the needle insertion direction, and the first slider is slidably connected to the guide hole.

[0010] Preferably, both sides of the guide hole are provided with positioning grooves, the first slider is provided with a spring groove, a positioning block is slidably installed in the spring groove, a positioning spring is fixedly installed between the positioning block and the spring groove, and the positioning block is adapted to engage with the positioning groove. The sides of the positioning block and the positioning groove that engage with each other are all set as inclined surfaces. When the thrust exceeds the friction between the inclined surfaces, the positioning block slides out of the positioning groove.

[0011] Preferably, a wide opening is provided on the other side of the straight cylinder, one end of the control rod extends from the end of the push tube away from the needle insertion direction and is fixedly connected to a push plate, the push plate extends from the wide opening to the outside of the straight cylinder, and a second slider is fixedly installed on the outside of the end of the push tube away from the needle insertion direction, the second slider being slidably connected to the wide opening.

[0012] Preferably, a guide rail is fixedly installed on the outer surface of the straight cylinder, and positioning holes are provided at both ends of the guide rail. A slot is provided at one end of the sliding positioning frame, and the slot is slidably adapted to the guide rail. Insertion holes penetrating into the slot are provided on both side walls of the sliding positioning frame. The sliding positioning frame is also provided with a locking plate, an insertion block, a pressure plate, and a rotating plate. The locking plates are slidably installed on both sides of the sliding positioning frame. The insertion block is fixedly installed on one end of the locking plate, and the insertion block penetrates the insertion hole and is adapted to the positioning hole for insertion. The pressure plate is movably disposed on the outside of the sliding positioning frame.

[0013] Preferably, a return spring is fixedly installed between the sliding positioning frame and the pressure plate.

[0014] Compared with the prior art, the present invention provides an auxiliary positioning needle insertion device for acupuncture, which has the following beneficial effects: 1. This acupuncture auxiliary positioning needle insertion device, by setting up a needle clamping and pushing component and an auxiliary positioning component, can stably clamp the acupuncture needle and guide the acupuncture needle to enter along a straight line. The contact ring can contact the patient's skin surface to locate the needle insertion position. When the needle is retained, the clamping rod can be quickly released and the device can be separated from the acupuncture needle. This solves the problems of existing devices being large in size and inflexible in use, as well as the difficulty in quickly releasing the acupuncture needle when it is retained.

[0015] 2. This acupuncture auxiliary positioning needle insertion device, by setting positioning grooves and positioning blocks, can provide multiple positioning points during the movement of the push tube, assisting the operator in controlling the insertion depth of the acupuncture needle, avoiding the needle from being inserted too deeply and causing harm to the patient, while maintaining the stability of the needle insertion process and improving the consistency of acupuncture operation.

[0016] 3. This acupuncture auxiliary positioning needle insertion device, by setting a sliding positioning frame and a contact ring, can adjust the position of the contact ring according to the length of the acupuncture needle. When installing the acupuncture needle, the contact ring can be completely fitted outside the straight cylinder to avoid contact with the acupuncture needle and reduce the risk of secondary contamination caused by the acupuncture needle coming into contact with non-sterile surfaces after unpacking.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1 Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6This invention provides an auxiliary positioning needle insertion device for acupuncture, including a straight cylinder 1 and an acupuncture needle 4. The straight cylinder 1 is provided with a needle clamping and pushing assembly 2 inside, and an auxiliary positioning assembly 3 is provided outside the straight cylinder 1. The needle clamping and pushing assembly 2 includes a push tube 21, a clamping rod 22, and a control rod 23. The push tube 21 is slidably installed inside the straight cylinder 1, the clamping rod 22 is slidably installed inside the push tube 21, and the control rod 23 is installed inside the push tube 21. The control rod 23 is convexly connected to the clamping rod 22. When the control rod 23 moves relative to the push tube 21, all the clamping rods 22 move away from each other to release the clamping of the needle handle of the acupuncture needle 4. The auxiliary positioning assembly 3 includes a sliding positioning frame 31, a connecting rod 32, and an abutment ring 33. The sliding positioning frame 31 is slidably installed on the outer side wall of the straight cylinder 1, and the abutment ring 33 is fixedly connected to the sliding positioning frame 31 through the connecting rod 32.

[0021] As can be seen from the above, the straight cylinder 1 serves as the main support structure of the device, providing a mounting base for the needle clamping and pushing assembly 2 and the auxiliary positioning assembly 3. The needle clamping and pushing assembly 2 can clamp the acupuncture needle 4 and drive the acupuncture needle 4 to move along the axis of the straight cylinder 1 to complete the needle insertion action. At the same time, it can quickly release the clamp on the handle of the acupuncture needle 4. The auxiliary positioning assembly 3 can locate the acupuncture position on the skin surface when inserting the needle and guide the acupuncture needle 4 to accurately insert into the predetermined acupoint.

[0022] When using this device, first move the auxiliary positioning component 3 to the rear end of the straight cylinder 1 so that the contact ring 33 is completely fitted outside the straight cylinder 1. Then, insert the acupuncture needle 4 into the push tube 21 from the front end of the straight cylinder 1 so that the needle handle of the acupuncture needle 4 is clamped and fixed by the clamping rod 22. Then, move the auxiliary positioning component 3 forward to a suitable position so that the needle tip of the acupuncture needle 4 is between the contact ring 33 and the end of the straight cylinder 1. Place the contact ring 33 on the outside of the acupuncture position on the patient's skin surface. Push the push tube 21 forward along the axis of the straight cylinder 1. The push tube 21 drives the clamping rod 22 and the acupuncture needle 4 to move forward together so that the needle tip of the acupuncture needle 4 passes through the center position of the contact ring 33 to contact the skin and complete the needle insertion. When it is necessary to retain the needle, operate the control rod 23 to move relative to the push tube 21 so that all the clamping rods 22 move away from each other and release the clamping of the needle handle of the acupuncture needle 4. Then, pull the straight cylinder 1 away from the skin along the length of the acupuncture needle 4.

[0023] Example 2 like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9As shown, the difference between this embodiment and the above embodiment is that a circular baffle 24 is fixedly installed at one end of the push tube 21. The circular baffle 24 has sliding holes 241 arranged in a ring array. The length direction of the sliding holes 241 coincides with the radial direction of the circular baffle 24. The clamping rod 22 is slidably installed inside the sliding holes 241, and a clamping pad 221 is fixedly installed on the clamping rod 22.

[0024] As can be seen from the above, the circular baffle 24 is fixed inside the push tube 21 to provide sliding support for the clamping rod 22. The sliding hole 241 is distributed radially along the circular baffle 24, which can restrict the sliding direction of the clamping rod 22, so that the clamping rod 22 can only move radially along the circular baffle 24. The clamping pad 221 is fixed at the end of the clamping rod 22, which can increase the friction between the clamping rod 22 and the needle handle of the acupuncture needle 4, and improve the stability of clamping.

[0025] The needle clamping and pushing assembly 2 also includes a turntable 25 and a rotating rod 26. The turntable 25 is fixedly installed at one end of the control rod 23, and push rods 251 arranged in a circular array are fixedly installed on the turntable 25 at a position off the center. The rotating rod 26 is arranged in a one-to-one correspondence with the push rods 251, and one end of the rotating rod 26 is rotatably connected to the corresponding push rod 251, and the other end of the rotating rod 26 is rotatably connected to the corresponding clamping rod 22.

[0026] As can be seen from the above, the turntable 25 is fixed to one end of the control rod 23 and can rotate and move together with the control rod 23. The push rods 251 are distributed in a circular array on the turntable 25 at positions off the center. The two ends of the rotating rod 26 are rotatably connected to the push rod 251 and the clamping rod 22 respectively. When the control rod 23 drives the turntable 25 to rotate, the push rod 251 drives the clamping rod 22 to slide along the sliding hole 241 through the rotating rod 26, thereby realizing the closing and opening of the clamping rod 22, thus completing the clamping and releasing of the needle handle of the acupuncture needle 4.

[0027] A fixing rod 242 is fixedly installed on the circular baffle 24, and a pull rod 252 is fixedly installed on the turntable 25. The needle clamping and pushing assembly 2 also includes a tension spring 27, the two ends of which are connected to the fixing rod 242 and the pull rod 252 respectively.

[0028] As can be seen from the above, the fixing rod 242 is fixed on the circular baffle 24, the pull rod 252 is fixed on the turntable 25, and the two ends of the tension spring 27 are connected to the fixing rod 242 and the pull rod 252 respectively, which can provide tension to the turntable 25, so that the turntable 25 remains in the initial position when it is not subjected to external force, thereby keeping the clamping rod 22 in the retracted state and stably clamping the needle handle of the acupuncture needle 4.

[0029] A guide hole 11 is provided on one side of the straight tube 1. A first slider 211 is fixedly installed on the outside of the end of the push tube 21 away from the needle 4. The first slider 211 is slidably connected to the guide hole 11.

[0030] As can be seen from the above, the guide hole 11 is opened on one side of the straight cylinder 1, and the first slider 211 is fixed to the outside of the push tube 21 and slidably connected to the guide hole 11. This can restrict the movement direction of the push tube 21, so that the push tube 21 can only move along the axial direction of the straight cylinder 1, preventing the push tube 21 from rotating during movement and ensuring the accuracy of the needle insertion direction.

[0031] Positioning grooves 111 are provided on both sides of the guide hole 11. A spring groove 212 is provided inside the first slider 211. A positioning block 213 is slidably installed in the spring groove 212. A positioning spring 214 is fixedly installed between the positioning block 213 and the spring groove 212. The positioning block 213 is adapted to engage with the positioning groove 111. The sides of the positioning block 213 and the positioning groove 111 that engage with each other are all set as inclined surfaces. When the thrust exceeds the friction between the inclined surfaces, the positioning block 213 slides out of the positioning groove 111.

[0032] As can be seen from the above, the positioning groove 111 is opened on both sides of the guide hole 11, the spring groove 212 is opened inside the first slider 211, the positioning block 213 is slidably installed in the spring groove 212, and the positioning spring 214 can push the positioning block 213 to extend outward and engage with the positioning groove 111. The engaging sides of the positioning block 213 and the positioning groove 111 are both inclined surfaces. When the pushing force exceeds the friction between the inclined surfaces, the positioning block 213 can slide out of the positioning groove 111, thereby providing multiple positioning points during the movement of the push tube 21 to assist the operator in controlling the insertion depth of the acupuncture needle 4.

[0033] A wide opening 12 is provided on the other side of the straight cylinder 1. One end of the control rod 23 extends from the end of the push tube 21 away from the needle insertion direction of the acupuncture needle 4 and is fixedly connected to the push plate 231. The push plate 231 extends from the wide opening 12 to the outside of the straight cylinder 1. A second slider 215 is fixedly installed on the outside of the end of the push tube 21 away from the needle insertion direction of the acupuncture needle 4. The second slider 215 is slidably connected to the wide opening 12.

[0034] As can be seen from the above, the wide opening 12 is opened on the other side of the straight cylinder 1, and the push plate 231 is fixed to one end of the control rod 23 and extends from the wide opening 12 to the outside of the straight cylinder 1. The operator can rotate the control rod 23 by pushing the push plate 231 along the circumference of the straight cylinder 1, thereby causing the clamping rod 22 to slide and loosen the clamping of the acupuncture needle 4. The second slider 215 is fixed to the outside of the push tube 21 and is slidably connected to the wide opening 12. It can limit the movement range of the push tube 21 and prevent the push tube 21 from shaking. At the same time, it can prevent accidental contact with the push plate 231 from causing the clamping to loosen.

[0035] Example 3 like Figure 5 , Figure 10 and Figure 11As shown, the difference between this embodiment and the above embodiment is that a guide rail 13 is fixedly installed on the outer surface of the straight cylinder 1. Positioning holes 131 are opened at both ends of the guide rail 13. A slot 311 is opened at one end of the sliding positioning frame 31. The slot 311 is slidably adapted to the guide rail 13. Insertion holes 312 that penetrate into the slot 311 are opened on both sides of the sliding positioning frame 31. The sliding positioning frame 31 is also provided with a locking plate 34, a plug 35, a pressure plate 36 and a rotating plate 37. The locking plate 34 is slidably installed on both sides of the sliding positioning frame 31. The plug 35 is fixedly installed on one end of the locking plate 34 and penetrates the insertion hole 312 and is adapted to be inserted into the positioning hole 131. The pressure plate 36 is movably arranged on the outside of the sliding positioning frame 31. One end of the rotating plate 37 is rotatably connected to the pressure plate 36, and the other end of the rotating plate 37 is rotatably connected to the locking plate 34 on the same side.

[0036] As can be seen from the above, the guide rail 13 is fixed on the outer surface of the straight cylinder 1 to provide sliding support for the sliding positioning frame 31. The slot 311 is opened at one end of the sliding positioning frame 31 and is slidably adapted to the guide rail 13, which can limit the sliding direction of the sliding positioning frame 31. The insertion hole 312 penetrates through the two side walls of the sliding positioning frame 31. The clamping plate 34 is slidably installed on both sides of the sliding positioning frame 31. The insertion block 35 is fixed at one end of the clamping plate 34 and can pass through the insertion hole 312 to be inserted into the positioning hole 131 on the guide rail 13. The pressure plate 36 is movably disposed on the outside of the sliding positioning frame 31. The two ends of the rotating plate 37 are rotatably connected to the pressure plate 36 and the clamping plate 34 respectively. When the pressure plate 36 is pressed, the rotating plate 37 drives the clamping plate 34 and the insertion block 35 to move outward, so that the insertion block 35 is dislodged from the positioning hole 131, thereby adjusting the position of the sliding positioning frame 31 on the guide rail 13.

[0037] A return spring 38 is fixedly installed between the sliding positioning frame 31 and the pressure plate 36.

[0038] As can be seen from the above, the reset spring 38 is fixed between the sliding positioning frame 31 and the pressure plate 36, which can provide an outward elastic force to the pressure plate 36, so that the pressure plate 36 is kept in the initial position when it is not subjected to external force, thereby keeping the insert block 35 in the state of being inserted into the positioning hole 131, and fixing the sliding positioning frame 31 in the predetermined position on the guide rail 13.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
