Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine acupuncture, and in particular to an acupuncture gun. Background Art

[0002] Acupuncture, as a traditional Chinese medicine, has a history of thousands of years. It regulates the body's yin and yang balance and blood circulation by stimulating the body's acupuncture points to achieve the purpose of treating diseases and maintaining health. Traditional acupuncture generally uses manual acupuncture to apply needles to the acupuncture points of the human body. On the one hand, the manual acupuncture method consumes a lot of time, is inefficient, and has high labor intensity for medical staff. On the other hand, the acupuncture needles need to be taken out of the packaging during acupuncture, so that the acupuncture needles are exposed to the air, which is easy to cause pollution and cannot guarantee the safety of use.

[0003] Therefore, there is an urgent need for an acupuncture gun to solve the above-mentioned technical problems. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides an acupuncture gun, which can realize automatic acupuncture at acupuncture points of the human body, improve acupuncture efficiency, reduce the labor intensity of medical staff, save time, and ensure safety of use.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] An acupuncture gun comprises a shell, a gun head plate, a needle firing module, a needle changing module, a needle feeding module and a needle pushing module; the top and bottom ends of the shell are respectively provided with a first opening and a second opening, and the first opening and the second opening are both communicated with the interior of the shell; one end of the shell is provided with a needle outlet channel, the needle outlet channel is located between the shell and the gun head plate, the interior of the needle outlet channel is communicated with the interior of the shell, the gun head plate is connected to the needle outlet channel, the gun head plate is provided with a needle outlet hole corresponding to the needle outlet channel, the needle firing module, the needle changing module, the needle feeding module and the needle pushing module are sequentially arranged in the shell along a direction close to the gun head plate, and the needle changing module is located between the first opening and the second opening.

[0007] The beneficial effects of the present invention are as follows: the acupuncture gun of the present invention is provided with a shell, a gun head plate, a needle-striking module, a needle-changing module, a needle-feeding module and a needle-pushing module. The needle-changing module can drive the package to move downward so that the cavities storing acupuncture needles of the package can be moved one by one between the needle-striking module and the needle-feeding module. The needle-striking module can strike the acupuncture needles in the cavities between the needle-striking module and the needle-feeding module so that the acupuncture needles are moved out of the cavities. The needle-feeding module can drive the acupuncture needles to move toward the gun head plate so that the needle tips of the needle bodies of the acupuncture needles can be moved out of the needle-pushing module, the needle-exiting channel and the needle-exiting channel in sequence. The needle passes through the hole and pierces the acupuncture part of the human body, and the piercing depth is the first predetermined depth. The acupuncture needle can be pushed to continue to move in the direction close to the gun head plate through the needle pushing module, so that the needle tip of the needle body of the acupuncture needle continues to pierce the acupuncture part of the human body, and the piercing depth is the second predetermined depth. In this way, the acupuncture part of the human body is automatically acupunctured, the acupuncture efficiency is improved, the labor intensity of medical staff is reduced, and time is saved. In the process of acupuncture, the acupuncture needle does not need to be taken out of the package, so that the acupuncture needle will not be exposed to the air, will not cause pollution, and ensure the safety of use. At the same time, the acupuncture gun with this structure is simple to operate, which is convenient for acupuncture training for medical staff and can reduce training costs.

[0039] The striker housing 31 is disposed in the first chamber 111 , one end of the striker housing 31 is disposed on an inner wall of the first chamber 111 close to the second chamber 123 , and the other end of the striker housing 31 is disposed on an inner wall of the first chamber 111 away from the second chamber 123 .

[0040] The two striker conductors 32 are respectively arranged at the bottom and the top of the striker housing 31. The striker conductor 32 is made of copper-chromium-zirconium alloy, which has good electrical conductivity. The striker conductive block 33 is made of the same material as the striker conductor 32. The striker conductive block 33 is located between the two striker conductors 32, and the top and bottom ends of the striker conductive block 33 are respectively in sliding contact with the two striker conductors 32. Since both the striker conductive block 33 and the striker conductor 32 are electrically conductive, the striker conductive block 33 is respectively electrically connected to the two striker conductors 32. Two striker slide grooves are respectively provided on the inner walls on both sides of the striker housing 31, and two striker sliders 34 are respectively provided on both sides of the striker conductive block 33 and are respectively slidably matched with the two striker slide grooves. In this embodiment, the striker slider 34 is T-shaped, and the shape of the striker slide groove matches the shape of the striker slider 34. The striker slider 34 is made of an insulating material, such as a plastic material. The striker 35 is arranged at one end of the striker conductive block 33 close to the gun head plate 20 and corresponds to the first through hole 128. The striker housing 31 is provided with a hole 311 corresponding to the striker 35 and the first through hole 128 at one end close to the gun head plate 20. The hole 311 is connected to the inside of the striker housing 31 and the first through hole 128. The striker 35 is used to strike the acupuncture needle 300 in the cavity 203 of the package 200. The striker housing 31 is provided with a mounting groove 312 at one end away from the gun head plate 20. The striker electronic commutator 36 is arranged in the mounting groove 312 and is electrically connected to one end of the two striker conductors 32 away from the gun head plate 20. The striker electronic commutator 36 is used to control the direction of the current.

[0041] In this embodiment, a commutator mounting plate 361 is provided in the striker housing 31, and a notch is provided at one end of the striker conductor 32 away from the gun head plate 20, and the top and bottom ends of the commutator mounting plate 361 respectively match the notches of the two striker conductors 32. Two protrusions 3611 arranged opposite to each other in the upper and lower directions are provided on one side of the commutator mounting plate 361 close to the mounting groove 312, and a first through hole 314 corresponding to the commutator mounting plate 361 and two second through holes 313 corresponding to the two protrusions 3611 are provided at the bottom of the mounting groove 312, and the first through hole 314 is located between the two second through holes 313, and the striker electronic commutator 36 partially passes through the first through hole 314 and is provided on one side of the commutator mounting plate 361 close to the mounting groove 312, and the two protrusions 3611 respectively match the two second through holes 313. The provided commutator mounting plate 361 plays a role of installation support for the striker electronic commutator 36.

[0042] Since the striker electronic commutator 36 is electrically connected to the ends of the two striker conductors 32 away from the gun head plate 20, and the striker conductive block 33 is electrically connected to the two striker conductors 32, the striker electronic commutator 36, the two striker conductors 32, and the striker conductive block 33 form a passage. When the striker electronic commutator 36 is energized, the current flows through the two striker conductors 32 and the striker conductive block 33, and a magnetic field is generated between the two striker conductors 32. The interaction between the magnetic field and the current can generate a magnetic field force, which changes the direction of the current through the striker electronic commutator 36, so that the striker conductive block 33 can be driven by the magnetic field force to move toward the direction close to the gun head plate 20 or away from the gun head plate 20, that is, to move left and right. Specifically, when the direction of the current is the striker electronic commutator 36-the striker conductor 32 located above-the striker When the conductive block 33-the striker conductor 32 located below-the striker electronic commutator 36, according to the right-hand rule, it can be determined that the direction of the magnetic field generated between the two striker conductors 32 is forward, and according to the left-hand rule and the direction of the magnetic field, it can be determined that the direction of the magnetic field force is rightward, and the striker conductive block 33 can be driven to move rightward by the rightward magnetic field force. When the direction of the current is the striker electronic commutator 36-the striker conductor 32 located below-the striker conductive block 33, and the striker conductor 32 located above-the striker electronic commutator 36, according to the right-hand rule, it can be determined that the direction of the magnetic field generated between the two striker conductors 32 is backward, and according to the left-hand rule and the direction of the magnetic field, it can be determined that the direction of the magnetic field force is leftward, and the striker conductive block 33 can be driven to move leftward by the leftward magnetic field force. The left-right movement of the striker conductive block 33 can drive the two striker sliders 34 to move left and right in the corresponding striker slide grooves and drive the striker 35 to move left and right. The two striker slide blocks 34 and the two striker slots can improve the stability of the movement of the striker conductive block 33, thereby improving the stability of the movement of the striker 35. By adjusting the magnitude of the current, the magnitude of the magnetic field force can be adjusted, and then the speed of the striker movement can be adjusted, so that the force of the striker 35 striking the acupuncture needle 300 can be adjusted.

[0048] The needle feeding electronic commutator 55 is arranged in the needle feeding housing 51 and is electrically connected to one end of the two needle feeding conductors 52 close to the gun head plate 20. In this embodiment, a commutator frame 551 is arranged in the needle feeding housing 51, and the commutator frame 551 is located between one end of the needle feeding conductor 52 close to the gun head plate 20 and the inner wall of one end of the needle feeding housing 51 close to the gun head plate 20, and the needle feeding electronic commutator 55 is arranged in the commutator frame 551. The commutator frame 551 is arranged to play the role of installation support for the needle feeding electronic commutator 55. The needle feeding electronic commutator 55 is used to control the direction of the current.

[0049] In actual application, since the needle feeding electronic commutator 55 is electrically connected to one end of the two needle feeding conductors 52 close to the gun head plate 20, and the needle feeding conductive block 53 is electrically connected to the two needle feeding conductors 52, the needle feeding electronic commutator 55, the two needle feeding conductors 52, and the needle feeding conductive block 53 form a passage. When the needle feeding electronic commutator 55 is energized, the current flows through the two needle feeding conductors 52 and the needle feeding conductive block 53, and a magnetic field is generated between the two needle feeding conductors 52. The magnetic field force generated by the interaction between the magnetic field and the current changes the direction of the current through the needle feeding electronic commutator 55, so that the needle feeding conductive block 53 can be driven to move toward the direction close to the gun head plate 20 or away from the gun head plate 20, that is, to move left and right. Specifically, when the direction of the current is the needle feeding electronic commutator 55-the needle feeding conductor 5 located in front 2-needle feeding conductive block 53-needle feeding conductor 52 at the rear-needle feeding electronic commutator 55, according to the right-hand rule, it can be determined that the direction of the magnetic field generated between the two needle feeding conductors 52 is upward, and according to the left-hand rule and the direction of the magnetic field, it can be determined that the direction of the magnetic field force is to the right, and the right-facing magnetic field force can drive the needle feeding conductive block 53 to move to the right. When the direction of the current is the striking pin electronic commutator 55-needle feeding conductor 52 at the rear-needle feeding conductive block 53 and the needle feeding conductor 52 at the front-needle feeding electronic commutator 55, according to the right-hand rule, it can be determined that the direction of the magnetic field generated between the two needle feeding conductors 52 is downward, and according to the left-hand rule and the direction of the magnetic field, it can be determined that the direction of the magnetic field force is to the left, and the left-facing magnetic field force can drive the needle feeding conductive block 53 to move to the right. The left and right movement of the needle feeding conductive block 53 can drive the first connecting block 531 and the second connecting block 532 to move left and right, thereby driving the needle feeding slider 54 to move left and right in the needle feeding slide groove 511 and the needle feeding limit plate 533 to move left and right in the fourth recess 513, and then driving the clamping member 543 to move left and right. The needle feeding limit plate 533 is set to limit the upward movement of the needle feeding slider 54. By adjusting the magnitude of the current, the magnitude of the magnetic field force can be adjusted, and then the speed of the clamping member 543 can be adjusted, so that the speed of feeding the acupuncture needle 300 into the needle pushing module 60 can be adjusted.

[0050] In this embodiment, a needle-feeding anti-slip member 5431 is provided at the top of the clamping member 543. The needle-feeding anti-slip member 5431 can increase the friction between the needle handle 302 of the acupuncture needle 300 and improve the clamping stability.

The needle delivery channel 132 guides the movement of the acupuncture needle 300, ensuring that the acupuncture needle 300 enters between the clamping parts 543 of the two needle delivery assemblies. The shape of the needle delivery channel 132 is funnel-shaped.

The threaded roller 64 is used to cooperate with the external thread of the needle handle 302 of the acupuncture needle 300. The two first needle push motors 63 are used to drive the two threaded rollers 64 to rotate respectively. When the two threaded rollers 64 are matched with the external threads of the needle handle 302 of the acupuncture needle 300, the rotation of the two threaded rollers 64 can drive the acupuncture needle 300 to move toward or away from the gun head plate 20, that is, to move left and right. The needle push plate 62 is provided with a through hole 621, and the through hole 621 corresponds to the clamping space and the space between the two threaded rollers 64.

The two threaded rollers 64 are driven to move up and down and forward and backward by the up and down driving components and the front and back driving components, so that the height position and the front and back position of the two threaded rollers 64 can be adjusted to ensure that the space between the two threaded rollers 64 corresponds to the third through hole 139, so that the acupuncture needle 300 can pass through the third through hole 139. By adjusting the rotation speed of the two first needle pushing motors 63, the rotation speed of the two threaded rollers 64 can be adjusted, and then the speed of pushing the acupuncture needle 300 can be adjusted.

[0054] In this embodiment, the threaded roller 64 includes a roller body 641, one end of which is connected to the output end of the corresponding first needle pushing motor 63, and the other end of which is close to the third through hole 139.

The two ends of the first transmission shaft 652 are respectively connected to the output ends of the two second push-pin motors 651, and the outer periphery of the first transmission shaft 652 is sleeved with two first transmission gears 653. The side of the push-pin frame 61 away from the gun head plate 20 is provided with two first racks 654 that are arranged front to back. The length direction of the first rack 654 is the same as the height direction of the push-pin frame 61, and the two first racks 654 are respectively meshed with the two first transmission gears 653.

[0057] The circuit board and the battery are both arranged in the housing 10, specifically in the first chamber 111. In this embodiment, a first support plate 112 is provided at the top of the first chamber 111, and the circuit board and the battery are both arranged at the bottom of the first support plate 112. The first support plate 112 is provided to support the circuit board and the battery. A switch 70 is provided at one end of the second part 12 of the housing 10 close to the gun head plate 20, and a touch screen 80 is provided on one side of the second part 12 of the housing 10, such as the front side. The battery, the switch 70, the touch screen 80, the striker electronic commutator 36 of the striker module 30, the needle exchange motor 41 of the needle exchange module 40, the needle feed electronic commutator 55 of the needle feed module 50, and the first needle push motor 63, the second needle push motor 651, and the third needle push motor 661 of the needle push module 60 are all electrically connected to the circuit board.

[0058] With the above structure, in actual application, the package 200 is first loaded into the guide channel 1261 in the second chamber 123 through the first opening 121, and the last cavity 203 of the package 200 is matched with one of the needle changing grooves 421 of the needle changing shaft 42 of the needle changing assembly located above, and the needle body 301 of the acupuncture needle 300 in each cavity 203 is close to the needle feeding module 50, and the needle handle 302 of the acupuncture needle 300 is close to the needle striking module 30. Then hold the second part 12, fit the gun head plate 20 to the skin of the part of the human body that needs acupuncture, and align the needle hole 21 with the acupuncture part. Then hold the part of the package 200 located outside the second chamber 123 and press the switch 70, the acupuncture gun starts working, and the needle changing motors 41 of the two needle changing assemblies 40 are started through the circuit board control, so that the package 200 can be driven to move downward through the needle changing motors 41 of the two needle changing assemblies to move the penultimate cavity 203 between the striker module 30 and the needle feeding module 50. At this time, the penultimate cavity 203 corresponds to the first through hole 128 and the second through hole 129 respectively, and the penultimate cavity 203 cooperates with one of the needle changing grooves 421 of the needle changing shaft 42 of the needle changing assembly located above. At the same time, the battery is controlled by the circuit board to power the striker electronic commutator 36, and the direction of the current is controlled by the striker electronic commutator 36 to be the striker electronic commutator 36-the striker conductor 32 located below-the striker conductive block 33, and the striker conductor 32 located above-the striker electronic commutator 36. In this way, a magnetic field can be generated between the two striker conductors 32. Under the action of the magnetic field force generated by the interaction between the magnetic field and the current, the striker conductive block 33 can be driven to move to the left, thereby driving the striker 35 to move to the left. After passing through the hole 33 of the striker 35 and the first through hole 128, the striker can strike the acupuncture needle 300 stored in the penultimate cavity 203 through the first sealing sheet of the penultimate cavity 203. Then, the direction of the current is controlled by the striker electronic commutator 36 to be the striker electronic commutator 36-the striker conductor 32 located above-the striker conductive block 33, and the striker conductor 32 located below-the striker electronic commutator 36. At this time, the magnetic field force is toward the right, and the magnetic field force can drive the striker conductive block 33 to move toward the right to return to the initial position, so as to prepare for the next work. Since the first sealing sheet of the cavity 203 has good elasticity, the first sealing sheet will not be punctured by the striker 35.

[0059] The acupuncture needle 300 stored in the penultimate cavity 203 will pierce the second sealing sheet 2031 in the penultimate cavity 203 under the impact of the striker 35 and move into between the clamping parts 543 of the two needle feeding assemblies through the second through hole 129 and the needle feeding channel 132. At this time, the needle body 301 of the acupuncture needle 300 is located on the left side of the clamping parts 543 of the two needle feeding assemblies, and the needle handle 302 of the acupuncture needle 300 is located in the clamping space, and the needle handle 302 of the acupuncture needle 300 can be clamped by the clamping parts 543 of the two needle feeding assemblies. In the process of the acupuncture needle 300 moving into the space between the clamping members 543 of the two needle delivery assemblies, since the outer diameter of the needle body 301 of the acupuncture needle 300 is smaller than the width of the clamping space, the needle body will not squeeze the clamping members 543 of the two needle delivery assemblies when entering the clamping space, and since the width of the clamping space is smaller than the maximum outer diameter of the needle handle 302 of the acupuncture needle 300, the needle handle 302 of the acupuncture needle 300 will squeeze the clamping members 543 of the two needle delivery assemblies when entering the clamping space, so that The clamping pieces 543 of the two needle feeding assemblies respectively move toward the direction approaching the corresponding needle feeding conductive block 53, thereby driving the corresponding needle feeding slider 54 to move toward the direction approaching the corresponding needle feeding conductive block 53, until the bottom end of the corresponding needle feeding slider 54 abuts against the bottom of the corresponding needle feeding groove 511, and the bottom end of the clamping piece 543 abuts against the top end of the needle feeding housing 51. At this time, the elastic piece is compressed, and under the action of the elastic piece, the needle handle 302 of the acupuncture needle 300 can be clamped by the clamping pieces 543 of the two needle feeding assemblies.

[0060] The battery is controlled by the circuit board to supply power to the needle feeding electronic commutators 55 of the two needle feeding assemblies. The directions of the current are controlled by the needle feeding electronic commutators 55 of the two needle feeding assemblies to be needle feeding electronic commutators 55-needle feeding conductor 52 at the rear-needle feeding conductive block 53, and needle feeding conductor 52 at the front-needle feeding electronic commutator 55. In this way, a magnetic field can be generated between the two needle feeding conductors 52 of the two needle feeding assemblies. Under the action of the magnetic field force generated by the interaction of the magnetic field and the current, the needle feeding conductive blocks 53 of the two needle feeding assemblies can be driven to move to the left. Then, the clamping parts 543 of the two needle delivery assemblies can be driven to move to the left, so that the acupuncture needle 300 can be driven to move to the left until the needle delivery conductive blocks 53 of the two needle delivery assemblies respectively abut against the corresponding commutator frames 551, so that the needle tip of the needle body 301 of the acupuncture needle 300 passes through the needle push frame 61 of the needle push module 60, the through hole 621 and the space between the two threaded rollers 64, the third through hole 139, the needle outlet channel 138 and the needle outlet hole 21 and penetrates into the acupuncture part of the human body, and the penetration depth is the first predetermined depth. At this time, the external thread of the needle handle 302 of the acupuncture needle 300 is threadedly matched with the two threaded rollers 64.

[0061] Then, the two first needle-pushing motors 63 are started to work through the control of the circuit board, so that the two first needle-pushing motors 63 can drive the two threaded rollers 64 to rotate, so that the two threaded rollers 64 can drive the acupuncture needle 300 to continue to move to the left. At the same time, the direction of the current is controlled by the two needle-feeding electronic commutators 55 of the two needle-feeding assemblies to be the needle-feeding electronic commutator 55-the needle-feeding conductor 52 located in the front-the needle-feeding conductive block 53, and the needle-feeding conductor 52 located in the back-the needle-feeding electronic commutator 55. At this time, the magnetic field force is toward the right, and the magnetic field force can drive the needle-feeding conductive blocks 53 of the two needle-feeding assemblies to move to the right to return to the initial position, and then drive the clamping parts 543 of the two needle-feeding assemblies to move to the right to return to the initial position, so as to prepare for the next work. When the acupuncture needle 300 is driven to continue to move to the left by the two threaded rollers 64, the needle tip of the needle body 301 of the acupuncture needle 300 can continue to pierce the acupuncture part of the human body, and the piercing depth is the second predetermined depth, so that the acupuncture is completed. After that, the switch 70 is pressed to stop the acupuncture gun from working, and then the acupuncture is continued to the next acupuncture site in the above manner.

[0062] Furthermore, the acupuncture gun also includes a heating module 90 and a temperature sensor 100 arranged in the third chamber 131 of the housing 10. The heating module 90 and the temperature sensor 100 are both electrically connected to the circuit board. The heating module 90 and the temperature sensor 100 are both close to one end of the third part 13 of the housing 10. The heating module 90 is located below the two threaded rollers 64 of the needle pusher module 60. The heating module 90 is arranged at the bottom of the third chamber 131 through the substrate. The heating module 90 is used to heat the acupuncture needle 300. The operation of the heating module 90 can be controlled by the circuit board. The heating temperature of the heating module 90 can be displayed by the touch display screen 80, and the heating temperature can be manually set. The heating module 90 is preferably a heating sheet. The temperature sensor 100 is, for example, an infrared temperature sensor. The temperature sensor 100 is located above the two threaded rollers 64 of the needle push module 60. A sensor mounting plate 135 is provided at the top of the third chamber 131. The temperature sensor 100 is arranged at the bottom of the sensor mounting plate 135. The temperature sensor 100 is used to detect the temperature of the acupuncture needle 300. The circuit board can control the temperature at which the heating module 90 heats the acupuncture needle 300 according to the temperature detected by the temperature sensor 100, so that the temperature at which the acupuncture needle 300 is heated can be adjusted. By heating the acupuncture needle 300, after the acupuncture needle 300 is inserted into the acupuncture site of the human body, through heat conduction, it can improve the microcirculation of the human body, promote metabolism, enhance immunity, promote local ablation of masses and nodules, etc. At the same time, it can soften or carbonize the acupuncture site and reduce the chance of acupuncture bleeding, etc.

[0063] Furthermore, the bottom end of the third part 13 of the housing 10 is provided with an irradiation module for irradiating the acupuncture site of the human body, and the irradiation module is electrically connected to the circuit board. The operation of the irradiation module can be controlled by the circuit board. By irradiating the acupuncture site of the human body, it is convenient for medical staff to know the acupuncture site, so that the acupuncture needle 300 can be accurately inserted into the acupuncture site of the human body. The irradiation module is preferably a laser ray lamp.

[0064] The acupuncture gun of the present invention is provided with a shell 10, a gun head plate 20, a needle-striking module 30, a needle-changing module 40, a needle-feeding module 50 and a needle-pushing module 60. The needle-changing module 40 can drive the package 200 to move downward so that the cavities 203 storing the acupuncture needles 300 of the package 200 are moved one by one between the needle-striking module 30 and the needle-feeding module 50. The needle-striking module 30 can strike the acupuncture needles 300 in the cavities 203 between the needle-striking module 30 and the needle-feeding module 50 so that the acupuncture needles 300 are moved out of the cavities 203. The needle-feeding module 50 can drive the acupuncture needles 300 to move in a direction close to the gun head plate 20 so that the needle tips of the needle bodies 301 of the acupuncture needles 300 are moved from the pusher 20 in sequence. The needle module 60, the needle outlet channel 138, and the needle outlet hole 21 pass through and penetrate into the acupuncture site of the human body, and the penetration depth is the first predetermined depth. The needle push module 60 can push the acupuncture needle 300 to continue to move toward the direction close to the gun head plate 20, so that the needle tip of the needle body 301 of the acupuncture needle 300 continues to penetrate into the acupuncture site of the human body, and the penetration depth is the second predetermined depth. In this way, the acupuncture site of the human body is automatically acupunctured, the acupuncture efficiency is improved, the labor intensity of medical staff is reduced, and time is saved.
