Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an intelligent electric painless acupuncture delivery device. Background Technology

[0002] Acupuncture, as an important component of traditional Chinese medicine, has had its efficacy widely verified in clinical practice. Currently, the most commonly used acupuncture procedure in clinical practice and daily health care is still the traditional manual needle insertion. This method typically involves the practitioner stabilizing the skin near the acupoint with one hand, while holding the metal needle in the other, and using the force applied by the wrist or fingers to insert the needle tip subcutaneously to the target depth.

[0003] In acupuncture, needle insertion is a crucial step, mainly involving retrieving needles from the kit, identifying acupoints, manually inserting the needle, releasing the needle, and then removing the next one. This manual needle retrieval and insertion method, especially in treatments requiring continuous acupuncture at multiple acupoints, necessitates the practitioner's hand repeatedly switching between the kit and the patient's skin, leading to distraction, fragmented movements, and reduced treatment efficiency. Furthermore, each needle retrieval represents a potential opportunity for contamination, requiring the practitioner to repeatedly ensure their fingers do not touch the needle or frequently disinfect their hands during continuous procedures, making the process cumbersome. Summary of the Invention

[0004] This invention aims to address at least one of the technical problems existing in the prior art. To this end, this invention provides an intelligent electric painless acupuncture insertion device, aiming to solve the problems of low diagnostic and treatment efficiency and increased risk of needle contamination caused by the need for frequent needle removal during manual acupuncture in related technologies.

[0005] This invention provides an intelligent electric painless acupuncture delivery device, comprising: The housing has a needle outlet at its front end; The acupuncture needle assembly includes a needle chamber, a rotating cylinder, and a rotary drive mechanism. The rotating cylinder is rotatably disposed inside the housing near the front end. The outer circumferential surface of the rotating cylinder has n needle grooves evenly distributed, where n ≥ 2. The needle grooves extend through both ends of the rotating cylinder along its axial direction. The needle chamber is arranged around the outside of the rotating cylinder, and a needle outlet slit connecting the inner and outer sides of the needle chamber is provided on the side of the needle chamber closest to the rotating cylinder. The rotary drive mechanism drives the rotating cylinder to rotate in a controlled manner, with each rotation angle being 360° / n. When the rotating cylinder is stationary, the needle outlet slit is aligned with one of the needle grooves, and one of the needle grooves is aligned with the needle outlet hole. A magnetic suction element is provided inside the needle groove. The gap between the inner wall of the needle chamber and the outer wall of the rotating cylinder is greater than zero and smaller than the outer diameter of the acupuncture needle. Each needle groove can only accommodate one acupuncture needle. The firing assembly, disposed within the housing, includes a firing pin, a first elastic element, and a toggle mechanism. The firing pin is slidably connected to the housing and is disposed on the side of the rotating cylinder away from the needle outlet. When the rotating cylinder is stationary, the firing pin, one of the needle grooves, and the needle outlet are coaxial. The toggle mechanism drives the firing pin to move away from the needle outlet. When the toggle mechanism releases the firing pin, the first elastic element drives the firing pin to move closer to the needle outlet, causing the end of the firing pin to strike the tail end of the acupuncture needle.

[0006] According to the intelligent electric painless acupuncture device provided by the present invention, the rotary drive mechanism includes a reciprocating linear motion component and a motion conversion component. The moving end of the reciprocating linear motion component reciprocates linearly in a direction parallel to the axis of the rotating cylinder. The reciprocating linear motion component is connected to the rotating cylinder through the motion conversion component. Each reciprocating motion of the reciprocating linear motion component drives the rotating cylinder to rotate by an angle of 360° / n through the motion conversion component.

[0007] According to the intelligent electric painless acupuncture induction device provided by the present invention, the motion conversion component includes: The cam body includes a cylindrical base rotatable about its own axis and multiple sets of grooves disposed on the outer surface of the cylindrical base. The cylindrical base is coaxially connected to the rotating cylinder at the end of the rotating cylinder away from the needle hole. The multiple sets of grooves are connected end to end and surround the cylindrical base. Each set of grooves includes a straight groove and a spiral groove. The straight groove extends in a direction parallel to the axis of the cylindrical base. The head end of the spiral groove is connected to the tail end of the straight groove of the adjacent groove. The tail end of the spiral groove is connected to the head end of the straight groove of the groove in which it is located. From the head end to the tail end of the spiral groove, the groove depth of the spiral groove gradually decreases. The groove depth of the straight groove is equal to the groove depth of the tail end of the spiral groove of the groove in which it is located. A drive slider is connected to the moving end of the reciprocating linear motion component and slides in the groove. A second elastic element is also provided between the drive slider and the moving end of the reciprocating linear motion mechanism. The extension and retraction direction of the second elastic element is along the radial direction of the cylindrical base.

[0008] According to the intelligent electric painless acupuncture device provided by the present invention, the reciprocating linear motion component includes: First rotary drive device; The first eccentric actuating member has its rotation center connected to the drive end of the first rotary driving device. A first sliding body is disposed on the side of the cylindrical base away from the rotating cylinder and slides in a direction parallel to the axial direction of the cylindrical base. One end of the first sliding body near the cylindrical base is connected to the driving slider. A first driven actuating member is disposed on the first sliding body and extends to the rotation path of the first eccentric actuating member. A third elastic element is disposed between the first sliding body and the housing; When the first rotary drive device drives the first eccentric actuator to rotate and the actuating end of the first eccentric actuator contacts the first driven actuator, it drives the first sliding body to move away from the cylindrical base. The third elastic element stores force. When the first eccentric actuator rotates until the actuating end disengages from the first driven actuator, the third elastic element drives the first sliding body to move closer to the cylindrical base.

[0009] The intelligent electric painless acupuncture induction device provided by the present invention includes, as follows: Second rotary drive device; The second eccentric actuating member has its rotation center connected to the drive end of the second rotary drive device. The second driven actuating member is disposed on the firing pin and extends into the rotation path of the second eccentric actuating member; When the first eccentric actuating member rotates until the actuating end disengages from the first driven actuating member, the second eccentric actuating member interacts with the second driven actuating member, driving the firing pin to move away from the rotating cylinder. The first elastic member stores force, and when the second eccentric actuating member separates from the second driven actuating member, the first elastic member drives the firing pin to move towards the rotating cylinder.

[0010] According to the intelligent electric painless acupuncture device provided by the present invention, the first eccentric actuating member and the second eccentric actuating member are disposed on a rotating disk, and the rotating disk is driven to rotate by the first rotating drive device or the second rotating drive device. The first eccentric actuating element is an active lever disposed on the end face of the rotating disk, the axis of the active lever being parallel to the axis of the rotating disk; the first driven actuating element is a driven lever disposed at the end of the first sliding body away from the cam body, the driven lever extending into the coverage area of ​​the end face of the rotating disk. The second eccentric actuating element is a gear tooth partially and continuously arranged on the outer peripheral surface of the rotating disk, and the second driven actuating element is a rack tooth arranged on the outside of the firing pin, wherein the rack tooth meshes with the gear tooth for transmission. The active lever is located on the radius line corresponding to the junction of the toothed and toothless parts of the rotating disk.

[0011] According to the intelligent electric painless acupuncture induction device provided by the present invention, the surface of the needle storage cavity of the needle chamber that contacts the needle tip is a spiral surface, and the spiral surface gradually approaches the needle outlet hole from the side away from the needle outlet slit to the side closer to the needle outlet slit.

[0012] According to the intelligent electric painless acupuncture inlet device provided by the present invention, a conduit is provided on the side of the needle chamber away from the firing component, and the conduit is coaxially arranged with the needle outlet.

[0013] According to the intelligent electric painless acupuncture device provided by the present invention, a laser indicator is also provided at the front end of the housing.

[0014] According to the intelligent electric painless acupuncture device provided by the present invention, the front end of the housing is further provided with a distance measuring device for measuring the distance between the front end of the housing and the human body.

[0015] The present invention has the following advantages due to the adoption of the above technical solutions: The intelligent electric painless acupuncture needle introducer provided by this invention has a needle chamber for storing acupuncture needles. During each acupuncture treatment, a rotary drive mechanism drives a rotating cylinder to rotate 360° / n, causing the empty needle slot located upstream of the needle exit slit to rotate to a position aligned with the needle exit slit. At this time, a magnetic attraction component in the needle slot draws an acupuncture needle from the needle chamber into the needle slot. Simultaneously, the needle slot located upstream of the firing position, which also contains the acupuncture needle, rotates to the firing position. In the firing position, the needle exit hole, needle slot, and firing pin are coaxial. Then, a prying mechanism drives the firing pin to move away from the rotating cylinder, while a first elastic element deforms and stores force. When the prying mechanism disengages from the firing pin, the first elastic element recovers its deformation and releases its elastic force, driving the firing pin to move closer to the needle exit hole, ultimately colliding with the tail end of the acupuncture needle, causing the acupuncture needle to be ejected through the needle exit hole. Furthermore, the gap between the inner wall of the needle chamber and the outer wall of the rotating cylinder is greater than zero and less than or equal to the outer diameter of the acupuncture needle. This ensures that the acupuncture needle will not enter the area between the inner wall of the needle chamber and the rotating cylinder, and the needle groove can only accommodate one acupuncture needle at a time. The intelligent electric painless acupuncture insertion device provided by this invention can achieve automatic needle replenishment and automatic firing, and can continuously and automatically administer acupuncture, solving the problem of frequent needle removal required during continuous acupuncture in related technologies.

[0025] The intelligent electric painless acupuncture needle introducer provided by this invention has a needle chamber for storing acupuncture needles. During each acupuncture treatment, a rotary drive mechanism drives a rotating cylinder to rotate 360° / n, causing the empty needle groove located downstream of the needle exit slit to rotate to a position aligned with the needle exit slit. At this time, a magnetic attraction component in the needle groove draws an acupuncture needle from the needle chamber into the needle groove. Simultaneously, the needle groove located downstream of the firing position, which also contains the acupuncture needle, rotates to the firing position. In the firing position, the needle exit hole, needle groove, and firing pin are coaxial. Then, a prying mechanism drives the firing pin to move away from the rotating cylinder, while a first elastic element deforms and stores force. When the prying mechanism disengages from the firing pin, the first elastic element returns to its original deformation and releases its elastic force, driving the firing pin to move closer to the needle exit hole, ultimately colliding with the tail end of the acupuncture needle, causing the acupuncture needle to be ejected through the needle exit hole. Furthermore, the gap between the inner wall of the needle chamber and the outer wall of the rotating cylinder is greater than zero and less than or equal to the outer diameter of the acupuncture needle. This ensures that the acupuncture needle will not enter the area between the inner wall of the needle chamber and the rotating cylinder, and the needle groove can only accommodate one acupuncture needle at a time. The intelligent electric painless acupuncture insertion device provided by this invention can achieve automatic needle replenishment and automatic firing, and can continuously and automatically administer acupuncture, solving the problem of frequent needle removal required during continuous acupuncture in related technologies.

[0026] The following is combined Figures 1 to 6 The present invention describes an intelligent electric painless acupuncture implantation device.

[0027] An embodiment of the present invention provides an intelligent electric painless acupuncture implantation device, including a housing 200, a needle replenishment assembly, and a firing assembly.

[0028] The front end of the housing 200 is provided with a needle outlet 210.

[0029] The acupuncture needle assembly includes a needle chamber 310, a rotating cylinder 320, and a rotary drive mechanism. The rotating cylinder 320 is rotatably disposed within the housing 200 and located near the front end of the housing 200. The rotation axis of the rotating cylinder 320 is parallel to the direction from the front end to the rear end of the housing 200. n needle grooves 321 are provided on the outer circumferential surface of the rotating cylinder 320. The n needle grooves 321 are evenly distributed circumferentially along the rotation axis, and adjacent needle grooves 321 are spaced 360° / n apart. Each needle groove 321 extends through both ends of the rotating cylinder 320 in a direction parallel to its axis, and each needle groove 321 can only accommodate one acupuncture needle 100. Each needle groove 321 is provided with a magnetic attractant for attracting the acupuncture needle 100.

[0030] The needle chamber 310 is arranged around the outside of the rotating cylinder 320. The gap between the inner wall of the needle chamber 310 and the outer wall of the rotating cylinder 320 is greater than zero, allowing the rotating cylinder 320 to rotate freely relative to the needle chamber 310. Simultaneously, the gap between the inner wall of the needle chamber 310 and the outer wall of the rotating cylinder 320 is smaller than the outer diameter of the acupuncture needle 100 to prevent the acupuncture needle 100 from entering between the inner wall of the needle chamber 310 and the outer wall of the rotating cylinder 320. A needle exit slit 311 is also provided on the inner wall of the needle chamber 310, connecting the inner and outer sides of the needle chamber 310, through which the acupuncture needle 100 inside the needle chamber 310 can be discharged.

[0031] The rotary drive mechanism is connected to the rotating cylinder 320. Each time the rotary drive mechanism is activated, it drives the rotating cylinder 320 to rotate by an angle of 360° / n.

[0032] When the intelligent electric painless acupuncture device is in an unused state, one of the needle grooves 321 is aligned with the needle outlet slit 311 on the needle chamber 310, and one of the needle grooves 321 is in the firing position. The needle groove 321 in the firing position is coaxial with the needle outlet 210. Along the rotation direction, all the needle grooves 321 between the needle outlet slit 311 and the firing position are filled with acupuncture needles 100. When the acupuncture needle 100 reaches the firing position with the needle groove 321, the acupuncture needle 100 is fired and ejected along the needle outlet 210. As the rotating cylinder 320 rotates, there are no acupuncture needles 100 in the needle groove 321 located between the firing position and the needle exit slit 311 along the rotation direction. When the needle groove 321 rotates with the rotating cylinder 320 to a position aligned with the needle exit slit 311, the magnetic attraction component in the needle groove 321 will draw the acupuncture needle 100 at the needle exit slit 311 into the needle groove 321.

[0033] The firing assembly is housed within the housing 200 and includes a firing pin, a first elastic element 420, and a toggle mechanism.

[0034] The firing pin is slidably connected to the housing 200, and the sliding direction is parallel to the axis of the rotating cylinder 320. The firing pin is located on the side of the rotating cylinder 320 away from the needle outlet 210, and the axis of the firing pin is collinear with the axis of the needle groove 321 located at the firing position.

[0035] The first elastic element 420 is disposed between the firing pin and the housing 200, and is used to provide the firing pin with an elastic force to move toward the rotating cylinder 320.

[0036] The actuating mechanism is used to drive the firing pin to move away from the rotating cylinder 320 when it is in contact with the firing pin. When the actuating mechanism is out of contact with the firing pin, the first elastic element 420 drives the firing pin to move rapidly towards the rotating cylinder 320.

[0037] When the needle groove 321, which holds the acupuncture needle 100, moves toward the firing position, the actuating mechanism simultaneously drives the firing pin to move away from the rotating cylinder 320, and the first elastic element 420 deforms and stores force. Before the firing pin disengages from the actuating mechanism, the needle groove 321, which holds the acupuncture needle 100, has already moved to the firing position. At this time, the actuating mechanism disengages from the firing pin, the first elastic element 420 recovers its deformation and releases its elastic force, driving the firing pin to move rapidly toward the rotating cylinder 320. Finally, the end of the firing pin collides with the tail end of the acupuncture needle 100, causing the acupuncture needle 100 to be ejected through the needle outlet 210.

[0038] The intelligent electric painless acupuncture device provided by this invention has a firing component that can automatically fire acupuncture needles 100. At the same time, the needle chamber 310 stores a certain number of acupuncture needles 100, which can automatically replenish the empty needle slots 321 when rotated to the needle exit slit 311. This solves the problem of frequent needle removal during continuous acupuncture in the prior art, improves acupuncture efficiency, and reduces the risk of contamination of acupuncture needles 100.

[0039] In some embodiments, the rotary drive mechanism includes a reciprocating linear motion component and a motion conversion component. The moving end of the reciprocating linear motion component reciprocates linearly along an axis parallel to the rotation axis. The motion conversion component is disposed between the moving end of the reciprocating linear motion component and the rotating cylinder 320, and is used to convert the reciprocating linear motion of the reciprocating linear motion into the rotational motion of the rotating cylinder 320. Each time the reciprocating linear motion component reciprocates once, the rotating cylinder 320 rotates through an angle of 360° / n.

[0040] In some embodiments, the motion conversion component may include a cam body and a drive slider 3324.

[0041] The cam body includes a cylindrical base 3321 and multiple sets of grooves disposed on the outer circumferential surface of the cylindrical base 3321. The cylindrical base 3321 can rotate around its own axis, and the cylindrical base 3321 is coaxially connected to the rotating shaft at the end of the rotating shaft away from the needle hole 210. The multiple sets of grooves are connected sequentially from end to end along the outer circumferential surface of the cylindrical base 3321 and surround the cylindrical base 3321, so that the multiple sets of grooves form a closed continuous annular groove.

[0042] Each set of grooves includes two parts: a straight groove 3322 and a spiral groove 3323. The straight groove 3322 extends along a direction parallel to the axis of the cylindrical base 3321. The head end of the spiral groove 3323 is connected to the tail end of the straight groove 3322 of the adjacent and upstream groove. The tail end of the spiral groove 3323 is connected to the head end of the straight groove 3322 in the same set.

[0043] The drive slider 3324 is connected to the moving end of the reciprocating linear motion component and slides in the groove.

[0044] From the head end to the tail end of the spiral groove 3323, the groove depth of the spiral groove 3323 gradually decreases, and the groove depth of the straight groove 3322 in the same group is the same as the depth of the tail end of the spiral groove 3323. This ensures that the drive slider 3324 can smoothly slide from the tail end of the spiral groove 3323 into the straight groove 3322.

[0045] Meanwhile, since the depth of the straight groove 3322 is the same as the depth of the tail end of the spiral groove 3323, the depth of the head end of the spiral groove 3323 is less than the depth of the straight groove 3322 in the adjacent group. Therefore, a step is formed between the tail end of the straight groove 3322 and the head end of the spiral groove 3323 in the adjacent group. When the drive slider 3324 moves to the tail end of the straight groove 3322 and continues to move, it will enter the head end of the spiral groove 3323 of the next group of grooves. Due to the existence of the step, when the reciprocating linear motion component drives the drive slider 3324 to move again, the drive slider 3324 can only move along the spiral groove 3323 it is in and will not return to the straight groove 3322 of the previous group of grooves.

[0046] Since the groove depth of the spiral groove 3323 gradually becomes shallower, a second elastic element is provided between the driving slider 3324 and the moving end of the reciprocating linear motion component. The extension and retraction direction of the second elastic element is along the radial direction of the cylindrical base 3321, which can make the driving slider 3324 move along the radial direction of the cylindrical base 3321 when it moves, so that the driving slider 3324 can adaptively adjust to the depth change of the spiral groove 3323, and can also make the driving slider 3324 closely fit the spiral groove 3323.

[0047] When the reciprocating linear motion assembly drives the drive slider 3324 to move away from the rotating cylinder 320, the drive slider 3324 slides along the spiral groove 3323 of its group. Since the drive slider 3324 only performs linear motion, it drives the cylindrical base 3321 to rotate during the sliding process. When the reciprocating linear motion assembly moves to the position furthest from the rotating cylinder 320, the drive slider 3324 moves to the tail end of the spiral groove 3323. At this time, the cylindrical base 3321 drives the rotating cylinder 320 to rotate 360° / n. Then, the reciprocating linear motion assembly moves towards the rotating cylinder 320, and the drive slider 3324 moves along the straight groove 3322 of the same group to the head end of the spiral groove 3323 of the adjacent group.

[0048] In some embodiments, the reciprocating linear motion assembly may include a first rotary drive device, a first eccentric actuator, a first slider 3311, and a third elastic element 3315.

[0049] The rotation center of the first eccentric actuating member is connected to the driving end of the first rotary driving device. When rotating, the actuating end of the first eccentric actuating member rotates eccentrically.

[0050] The first sliding body 3311 is located on the side of the cylindrical base 3321 away from the rotating cylinder 320 and slides in a direction parallel to the axis of the cylindrical base 3321. A cantilever 3312 extending forward is provided at the front end of the first sliding body 3311. The cantilever 3312 extends to the outer wall of the cylindrical base 3321, and the head end of the cantilever 3312 is connected to the drive slider 3324 on the side close to the cylindrical base 3321.

[0051] At the tail end of the first sliding body 3311, that is, at the end away from the cylindrical base 3321, a first driven actuating member is provided. The first driven actuating member extends to the rotation path of the first eccentric actuating member. When the first driven actuating member interacts with the first eccentric actuating member, the actuating end of the first eccentric actuating member drives the first driven actuating member to move away from the cylindrical base 3321. In turn, the first sliding body 3311 drives the driving slider 3324 to move along the spiral groove 3323. When the first eccentric actuating member rotates to the area where it is disengaged from the first driven actuating member, the first eccentric actuating member disengages from the first driven actuating member.

[0052] The third elastic element 3315 is disposed between the first sliding body 3311 and the housing 200, and is used to provide an elastic force to drive the first sliding body 3311 to move toward the cylindrical base 3321.

[0053] When the first eccentric actuator rotates to the position of contact with the first driven actuator, the movement of the first eccentric actuator causes the first driven actuator to move away from the cylindrical base 3321. This, in turn, drives the drive slider 3324 along the spiral groove 3323 via the first sliding body 3311 and the cantilever 3312. Simultaneously, the third elastic element 3315 deforms and stores energy. When the first eccentric actuator rotates to the position where it is about to separate from the first driven actuator, the drive slider 3324 moves to the tail end of the spiral groove 3323 and enters the head end of the straight groove 3322 in the same group. Then, the first eccentric actuator separates from the first driven actuator, and the third elastic element 3315 recovers its deformation and releases its elastic force, causing the first sliding body 3311 to move closer to the cylindrical base 3321. This, in turn, causes the drive slider 3324 to move to the tail end of the straight groove 3322 and enters the head end of the spiral groove 3323 in the adjacent group.

[0054] In some embodiments, the actuating mechanism includes a second rotary drive, a second eccentric actuating element, and a second driven actuating element.

[0055] The rotation center of the second eccentric actuating member is connected to the drive end of the second rotary drive device. When rotating, the actuating end of the second eccentric actuating member rotates eccentrically.

[0056] The firing pin is positioned on the side of the rotating cylinder 320 away from the needle outlet 210 and slides in a direction parallel to the axis of the rotating cylinder 320. The axis of the firing pin, the axis of the needle groove 321 located at the firing position, and the axis of the needle outlet 210 are coaxial.

[0057] The second driven actuating member is located at the tail end of the firing pin, that is, at the end away from the rotating cylinder 320. When the second driven actuating member interacts with the second eccentric actuating member, the second eccentric actuating member drives the second driven actuating member to move away from the rotating cylinder 320. When the second eccentric actuating member rotates to the area where it is disengaged from the second driven actuating member, the second eccentric actuating member disengages from the second driven actuating member.

[0058] When the second eccentric actuator rotates to the position of contacting the second driven actuator, the movement of the second eccentric actuator causes the second driven actuator to move away from the rotating cylinder 320, while the first elastic element 420 deforms and stores force. When the second eccentric actuator separates from the second driven actuator, the first elastic element 420 recovers its deformation and releases its elastic force, causing the firing pin to move towards the rotating cylinder 320, and finally collides with the tail end of the acupuncture needle 100 in the needle groove 321 at the firing position, causing the acupuncture needle 100 to be ejected from the needle outlet 210.

[0059] In one specific embodiment, the first eccentric actuating element and the second eccentric actuating element can be simultaneously disposed on a rotating disk 510. Only one of the first and second rotary driving devices needs to be disposed, which can be referred to as a rotary driving device. The rotary driving device may include a motor 520, a battery 530 and a switch 540. The motor 520 is used for transmission connection with the rotating disk 510.

[0060] See Figure 1 The first sliding body 3311 is located on the side of the cylindrical base 3321 away from the rotating cylinder 320, and its front end is connected to the drive slider 3324 via a cantilever 3312. The firing pin includes a firing pin body 411 and a second sliding body 412. The second sliding body 412 is located on the side of the first sliding body 3311 away from the cylindrical base 3321. The firing pin body 411 is located at the front end of the second sliding body 412, passes through the first sliding body 3311, and extends to the firing position attachment. The firing pin body 411 and the first sliding body 3311 slide in cooperation.

[0061] It should be noted that, in order to prevent the main body of the firing pin 411 from obstructing the rotation of the rotating cylinder 320, the front end of the firing pin air injection 411 will never enter the needle groove 321 of the rotating cylinder 320.

[0062] The rotating disk 510 is located below the second sliding body 412. The second eccentric actuating member can be a gear tooth 431 located on the outer circumferential surface of the rotating disk 510. The gear tooth 431 is partially and continuously located on the rotating disk 510. The outer circumferential surface of the disk is divided into a toothed part and a toothless part. The second driven actuating member is a rack tooth 432 located at the bottom of the second sliding body 412. The rack tooth 432 is used to mesh with the gear tooth 431 for transmission.

[0063] An extension arm 3316 extending rearward can be provided at the tail end of the first sliding body 3311. The extension arm 3316 is located on one side of the rack tooth 432 and extends above the rotating disk 510. The first driven actuating member can be a driven lever 3313 provided at the extended end of the extension arm 3316. The driven lever 3313 extends downward until it reaches the end face coverage area of ​​the rotating disk 510. The first eccentric actuating member can be an active lever 3314 provided on the end face of the rotating disk 510. The active lever 3314 has a cylindrical structure and extends in a direction parallel to the axis of the rotating disk 510.

[0064] Furthermore, the active lever 3314 is positioned on the radius line corresponding to the junction of the toothed and toothless parts of the rotating disk 510.

[0065] As the rotating disk 510 rotates, the active lever 3314 first contacts the driven lever 3313. At this time, the gear teeth 431 and the rack teeth 432 are not in contact. However, since the second sliding body 412 is located behind the first sliding body 3311, the active lever 3314 drives the driven lever 3313 to rotate, and through the extension arm 3316, it drives the first sliding body 3311 to move to the left, and at the same time drives the second sliding body 412 to move to the left as well.

[0066] Therefore, during the leftward movement of the first slider 3311, the driven slider 3324 rotates along the spiral groove 3323, driving the cylindrical base 3321 to rotate, which in turn drives the rotating cylinder 320 to rotate. At the same time, the firing pin body 411 also moves to the left with the second slider 412 and exits the firing position. Therefore, when the next acupuncture needle 100 moves to the firing position, the firing pin body 411 has already exited the firing position and will not interfere with the acupuncture needle 100.

[0067] When the active lever 3314 moves to the position where it disengages from the driven lever 3313, or before it moves to the position where it disengages from the driven lever 3313, the gear teeth 431 on the rotating disk 510 mesh with the rack teeth 432 at the bottom of the second sliding body 412, continuing to drive the second sliding body 412 and the firing pin body 411 to move to the left. However, the driven lever 3313 has already separated from the active lever 3314, and the third elastic element 3315 drives the first sliding body 3311 to move to the right, causing the drive slider 3324 to move along the straight groove 3322 of its group to the spiral groove 3323 of the adjacent group to wait for the next rotation. At this time, the needle groove 321 that adsorbs the acupuncture needle 100 has rotated to the firing position to wait for firing.

[0068] When the rotating disk 510 rotates to the position where the toothless part corresponds to the rack tooth 432, the rotating disk 510 loses its driving effect on the second sliding body 412 and releases the second sliding body 412. At this time, the first elastic element 420 drives the second sliding body 412 and the firing pin body 411 to move quickly to the right. The firing pin body 411 strikes the tail end of the acupuncture needle 100, thereby causing the acupuncture needle 100 to be ejected along the needle hole 210.

[0069] In some embodiments, the surface of the needle storage cavity of the needle chamber 310 that contacts the needle tip is a spiral surface, which gradually approaches the needle outlet 210 from the side away from the needle outlet slit 311 to the side closer to the needle outlet slit 311. Thus, during use, when the needle outlet 210 is facing downwards, the acupuncture needle 100 in the needle chamber 310 will slide along the spiral surface towards the needle outlet slit 311 under the action of gravity, achieving an automatic replacement effect.

[0070] Of course, a fourth elastic element can also be provided in the needle chamber 310. The fourth elastic element can be a spring, which is located in the needle chamber on the side away from the needle exit slit 311 and between the needle and the acupuncture needle 100, and is used to push the acupuncture needle 100 to move in the direction of the needle exit slit 311.

[0071] In some embodiments, a conduit 600 is provided on the side of the needle chamber 310 away from the firing assembly. The conduit 600 is coaxially arranged with the needle outlet 210. The conduit 600 can correct the track of the ejected acupuncture needle 100 to ensure the accuracy of needle dispensing.

[0072] Since there is a slight deviation between the human eye and the position of the needle outlet 210 during use, in order to prevent the intelligent electric painless acupuncture implanter from failing to accurately hit the target area when it is far away from the human body, in some embodiments, a laser indicator 700 is added to the front end of the housing 200 so that the intelligent electric painless acupuncture implanter can make the user clearer about the needle's landing point no matter how far away the user is.

[0073] In some embodiments, a ranging device, such as an infrared rangefinder 800, is also provided at the front end of the housing 200, which can intelligently detect the distance between the front end of the housing 200 and the human body. Since the depth of acupuncture needle insertion varies depending on the symptoms, the force can be adjusted by controlling the distance between the front end of the housing 200 and the human body, thus better controlling the depth of acupuncture needle insertion into the skin.

[0074] In addition, a speaker 900 can be installed inside the housing 200, mainly to remind the acupuncturist and the recipient when the acupuncture needle 100 will be fired, giving the user and patient more time to react.

[0075] Secondly, a small display screen can be installed to show information such as the device's battery level and the remaining quantity of acupuncture needles.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
