Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a needle-pushing mechanism and a continuous acupuncture device. Background Technology

[0002] Acupuncture is a general term for needling and moxibustion. Needling refers to inserting needles (usually filiform needles) into the patient's body at a certain angle under the guidance of traditional Chinese medicine theory, and using needling techniques such as twisting and lifting to stimulate specific parts of the body to achieve the purpose of treating diseases. Moxibustion involves burning or fumigating pre-made moxa cones or moxa sticks on certain acupoints on the body surface, using heat stimulation to prevent and treat diseases.

[0003] A continuous acupuncture device with announcement number CN101137342B has an internal transmitting component that can only extend the acupuncture needles by a fixed amount, resulting in a fixed force for the needles to be extended. This force cannot be adjusted, hindering the adjustment of acupuncture depth for different patient areas. Furthermore, it has a fixed needle box for storing the needles, which is directly mounted on the continuous acupuncture device. Replacing the needle box requires considerable force to pull it out, and installing it also requires considerable force to snap it in. Both the installation and disassembly processes are inconvenient, leading to prolonged interruptions during acupuncture and hindering medical staff from quickly changing needle boxes and providing smooth, continuous acupuncture to patients.

[0004] Therefore, it is necessary to propose a needle-pushing mechanism and a continuous acupuncture device to adjust the depth of acupuncture, while also enabling quick replacement of the needle box to facilitate smooth continuous acupuncture. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes a needle-pushing mechanism and a continuous acupuncture device to adjust the depth of acupuncture, while also enabling quick replacement of the needle box for smooth, continuous acupuncture.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a pusher mechanism, including a gear adjustment component and a pusher pop-out component. The gear adjustment component and one end of the pusher pop-out component form a stop-limit rotational connection, so that the gear adjustment component can be rotated to multiple gears, thereby adjusting the pop-out length of the pusher pop-out component.

[0008] Furthermore, one end of the push pin ejection assembly is provided with a connecting portion, and the push pin mechanism also includes a first elastic abutment member. One end of the first elastic abutment member is housed in the connecting portion and elastically abuts against the connecting portion. The gear adjustment member is rotatably connected to the connecting portion, and the other end of the first elastic abutment member abuts against the gear adjustment member.

[0009] Furthermore, the connecting part is provided with a connecting post, and the gear adjustment component forms a rotatable connection around the outer periphery of the connecting post.

[0010] Furthermore, the connecting column is provided with a mounting boss, and the first elastic abutment is housed in the mounting boss, with one end of the first elastic abutment elastically abutting against the inner sidewall of the gear adjustment component.

[0011] Furthermore, the ejector pin assembly includes a fixed frame, an ejector pin component, an elastic element, and a pressing handle. Both sides of the ejector pin component are slidably connected to the fixed frame. One end of the pressing handle is inserted into the fixed frame and slidably connected to it. A portion of the ejector pin component is housed within the pressing handle and slidably connected to it. One end of the elastic element abuts against one end of the ejector pin component, and the other end of the elastic element abuts against the interior of the pressing handle. When the pressing handle is pressed towards the fixed frame, the elastic element is compressed and stored. When the pressing handle is pressed to its end, the ejector pin component is actuated, causing it to eject rapidly towards the outside of the fixed frame due to the compressive force of the elastic element.

[0012] Furthermore, a sliding rod is provided on one side of the pusher, and a sliding groove is provided on one side of the fixing frame. A portion of the sliding rod is housed in the sliding groove, and the gear adjustment component is aligned with the sliding groove.

[0013] Furthermore, the gear adjustment component has multiple gear steps on its outer periphery, and rotating the gear adjustment component can align one of the gear steps with the sliding groove.

[0014] Furthermore, the pressing handle includes a sliding rod, a second elastic abutment, and a pressing rod. One end of the sliding rod is inserted into the fixed frame and slidably connected to the fixed frame. A portion of the pusher is housed in the sliding rod and slidably connected to the sliding rod. The pressing rod forms a stop-limit rotational connection with the other end of the sliding rod through the second elastic abutment, allowing the pressing rod to be rotated to adjust the position, thereby locking the pusher out.

[0015] A continuous acupuncture device, according to the aforementioned needle-pushing mechanism, includes a housing, the needle-pushing mechanism, and an acupuncture needle magazine. The needle-pushing mechanism is fixedly connected to the housing. The housing is provided with a mounting groove, which is aligned with one end of the needle-pushing mechanism. The acupuncture needle magazine is detachably connected to the mounting groove. By pressing the needle-pushing mechanism sequentially, the acupuncture needles in the acupuncture needle magazine can be ejected one by one.

[0016] Furthermore, the acupuncture needle cartridge is provided with two needle outlet channels, which are arranged side by side in opposite directions. The needle pusher is located on one side of the center line of the mounting groove and aligned with one of the needle outlet channels. After the acupuncture needles in one of the needle outlet channels are used up, the acupuncture needle cartridge is pulled out of the mounting groove and rotated 180 degrees before being put back into the mounting groove to continue acupuncture use.

[0017] The beneficial effects of this utility model are:

[0018] 1. The needle-pushing mechanism of this utility model uses a gear adjustment component to adjust the ejection length of the needle-pushing component in multiple gears, so that the needle-pushing component can have multiple different ejection lengths, thereby adjusting the pushing force of the acupuncture needle, so as to facilitate the adjustment of the acupuncture depth.

[0019] 2. The continuous acupuncture device of this utility model adopts a detachable form for installing the acupuncture needle cartridge. An installation groove is provided on the shell. When installing the acupuncture needle cartridge, the acupuncture needle cartridge is simply inserted into the installation groove to complete the installation. Then, the acupuncture needles in the acupuncture needle cartridge can be released one by one by pressing the needle pushing mechanism. When disassembling, the acupuncture needle cartridge is simply pulled out from the installation groove, which is convenient and quick.

[0020] In summary, this needle-pushing mechanism and continuous acupuncture device can conveniently adjust the depth of acupuncture and also allow for quick replacement of the needle box, facilitating smooth continuous acupuncture. Attached Figure Description

[0033] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0034] Please refer to Figures 1-2 This utility model proposes a pusher mechanism, including a gear adjustment component 1 and a pusher ejection component 2. The gear adjustment component 1 and one end of the pusher ejection component 2 form a stop-limit rotational connection, so that the gear adjustment component 1 can be rotated to multiple gears, thereby adjusting the ejection length of the pusher ejection component 2.

[0035] In this embodiment, the push needle ejection assembly 2 is adjusted to multiple positions using the gear adjustment component 1, so that the push needle ejection assembly 2 can have multiple different ejection lengths. When different ejection lengths act on the acupuncture needle, they will produce different forces, thereby adjusting the ejection force of the acupuncture needle to facilitate the adjustment of the acupuncture depth. When adjusting the gear of the push needle ejection assembly 2, the gear adjustment component 1 is rotated. When it is rotated to a certain position, the gear adjustment component 1 will pause. At this time, the adjustment of one position is completed. There are a total of 3 positions, so that the ejection length of the push needle ejection assembly 2 has 3 extensions, so that there are 3 acupuncture depths to adjust during acupuncture.

[0036] In this embodiment, one end of the push pin ejection assembly 2 is provided with a connecting part 21, and the push pin mechanism also includes a first elastic abutment member 3. One end of the first elastic abutment member 3 is housed in the connecting part 21 and elastically abuts against the connecting part 21. The gear adjustment member 1 is rotatably connected to the connecting part 21, and the other end of the first elastic abutment member 3 abuts against the gear adjustment member 1. The first elastic abutment member 3 is used to apply an elastic abutment force to the gear adjustment member 1, so that when the gear adjustment member 1 is rotated, the first elastic abutment member 3 can increase the resistance, so that when the gear adjustment member 1 is rotated to a gear, it can stay stably.

[0037] In this embodiment, the connecting part 21 is provided with a connecting post 211, and the gear adjustment member 1 forms a rotatable connection around the outer periphery of the connecting post 211. The connecting post 211 provides a rotatable support structure for the gear adjustment member 1, so that the gear adjustment member 1 can rotate smoothly.

[0038] In this embodiment, the connecting column 211 is provided with a mounting boss 2111, and the first elastic abutment 3 is housed in the mounting boss 2111. One end of the first elastic abutment 3 elastically abuts against the inner sidewall of the gear adjustment member 1. The mounting boss 2111 is used to provide a fixed placement structure for the first elastic abutment 3, so that the first elastic abutment 3 can elastically abut against the inner sidewall of the gear adjustment member 1, reducing the external space occupied.

[0039] In this embodiment, the push pin ejection assembly 2 includes a fixed frame 22, a push pin component 23, an elastic element 24, and a pressing handle 25. Both sides of the push pin component 23 are slidably connected to the fixed frame 22. One end of the pressing handle 25 is inserted into the fixed frame 22 and slidably connected to the fixed frame 22. A portion of the push pin component 23 is housed in the pressing handle 25 and slidably connected to the pressing handle 25. One end of the elastic element 24 abuts against one end of the push pin component 23, and the other end of the elastic element 24 abuts against the inside of the pressing handle 25. When the pressing handle 25 is pressed towards the fixed frame 22, the elastic element 24 can be squeezed and stored. When the pressing handle 25 is pressed to its end, the push pin component 23 is actuated, so that the push pin component 23 is quickly ejected towards the outside of the fixed frame 22 by the squeezing force of the elastic element 24. The connecting part 21 is provided on one side of the fixed frame 22. At the end, the fixing frame 22 provides a sliding guide structure for the pressing handle 25 and the push needle component 23. When the pressing handle 25 is pressed towards the fixing frame 22, the push needle component 23 is held still by the slot of the fixing frame 22. At this time, the elastic element 24 is compressed and stored. When the pressing handle 25 is pressed to the end, the pressing handle 25 will push the push needle component 23 to one side in the form of a slanted groove, so that the push needle component 23 slides sideways to slide out of the slot of the fixing frame 22. Since the push needle component 23 loses support, the compressed elastic element 24 will rebound and generate a rebound force. Since the pressing handle 25 is already at the end of the pressing position, the elastic element 24 rebounds by pushing the push needle component 23 towards the fixing frame 22. At this time, the front half of the push needle component 23 is pushed out of the fixing frame 22 by the elastic element 24.

[0040] In this embodiment, a sliding rod 231 is provided on one side of the pusher 23, and a sliding groove 221 is provided on one side of the fixing frame 22. A portion of the sliding rod 231 is housed in the sliding groove 221, and the gear adjustment member 1 is aligned with the sliding groove 221. When the pressing handle 25 is pressed to the end, the pressing handle 25 will move the sliding rod 231 to one side in the form of a slanted groove, so that the sliding rod 231 is moved into the sliding groove 221 and continues to slide under the rebound force of the elastic member 24.

[0041] In this embodiment, the gear adjustment member 1 has multiple gear steps 11 on its outer periphery. Rotating the gear adjustment member 1 allows one of the gear steps 11 to align with the sliding groove 221. When adjusting the gear using the gear adjustment member 1, the gear adjustment member 1 is rotated so that one of the gear steps 11 aligns with the sliding groove 221. When the handle 25 is pressed to move the sliding rod 231 to one side in the form of an inclined groove, so that the sliding rod 231 is moved into the sliding groove 221, the maximum length of the sliding groove 221 is determined by the amount of obstruction of the gear step 11. For example... The gear adjustment component 1 has three gear steps 11, namely gear step 11a, gear step 11b, and gear step 11c. The height of gear step 11a is greater than the height of gear step 11b, and the height of gear step 11b is greater than the height of gear step 11c. When gear step 11a rotates to align with the sliding groove 221, the maximum length of the sliding groove 221 is the shortest, that is, the length of the push pin component 23 that pops out of the fixed frame 22 is the shortest. This is the smallest gear. Similarly, gear step 11b is the medium gear, and gear step 11c is the largest gear.

[0042] In this embodiment, the pressing handle 25 includes a sliding rod 251, a second elastic abutment member 252, and a pressing rod 253. One end of the sliding rod 251 is inserted into the fixing frame 22 and slidably connected to the fixing frame 22. A portion of the pusher pin 23 is housed in the sliding rod 251 and slidably connected to the sliding rod 251. The pressing rod 253 forms a stop-limiting rotational connection with the other end of the sliding rod 251 through the second elastic abutment member 252, allowing the pressing rod 253 to be rotated to adjust the position, thereby locking the pusher pin 23 from popping out. 3. When pressed, the sliding rod 251 is directly pushed towards the fixed frame 22, at which time the elastic element 24 is compressed and stores force. If the pressing rod 253 is pressed to the end, the sliding rod 251 will push the pusher 23 to one side in the form of an inclined groove, so that the sliding rod 231 in the pusher 23 is pushed into the sliding groove 221, and continues to slide under the rebound force of the elastic element 24. In order to prevent the pusher 23 from being accidentally triggered and popped out when the present invention is not in use, the pressing rod 253 is connected to the second elastic abutment 252. The other end of the sliding rod 251 forms a stop-limit rotational connection, allowing the pressing rod 253 to be rotated to adjust the position, thereby locking the ejection of the push pin 23. The pressing rod 253 has a slot 2531, and one end of the fixing bracket 22 has a boss 222. When locking, the pressing rod 253 is rotated to the locked position. At this time, the second elastic abutment 252 will elastically lock and abut the pressing rod 253, keeping the pressing rod 253 in the locked position. At this time, the slot 2531 and the boss 222 are misaligned, and the slot 2531... The misalignment between the push rod 253 and the boss 222 prevents the push rod 253 from triggering the ejection of the push pin 23. Even when the push rod 253 is pressed, it cannot be pressed to the end and cannot move the push pin 23 toward the sliding groove 221, thus preventing the push pin 23 from being ejected. This is the locking position. When this utility model is needed, the push rod 253 can be rotated to the working position. At this time, the groove 2531 and the boss 222 are aligned, and the push pin 23 can be triggered to eject when the push rod 253 is pressed.

[0043] Please refer to Figures 1-5 A continuous acupuncture device, according to the above-mentioned needle pushing mechanism, includes a housing 4, a needle pushing mechanism, and an acupuncture needle magazine 5. The needle pushing mechanism is fixedly connected to the housing 4. The housing 4 is provided with an installation groove 41, which is aligned with one end of the needle pushing mechanism. The acupuncture needle magazine 5 is detachably connected to the installation groove 41. Pressing the needle pushing mechanism one by one can eject the acupuncture needles in the acupuncture needle magazine 5.

[0044] In this embodiment, the acupuncture needle cartridge 5 is detachably installed for convenient installation. An installation groove 41 is provided on the housing 4. When installing the acupuncture needle cartridge 5, it is simply inserted into the installation groove 41. The housing 4 is provided with a first magnet 42, which is located on the back of the installation groove 41 and close to the groove. A second magnet 52 is provided at the bottom of the acupuncture needle cartridge 5. After the acupuncture needle cartridge 5 is inserted into the installation groove 41, the first magnet 42 and the second magnet 52 are magnetically attracted to securely fix the acupuncture needle cartridge 5 in the installation groove 41. Then, by pressing the needle pushing mechanism one by one, the acupuncture needles in the acupuncture needle cartridge 5 can be ejected one by one. When disassembling, the acupuncture needle cartridge 5 can be directly pulled out from the installation groove 41, which is convenient and quick.

[0045] In summary, this needle-pushing mechanism and continuous acupuncture device can conveniently adjust the depth of acupuncture and also allow for quick replacement of the needle box, facilitating smooth continuous acupuncture.

[0046] In this embodiment, the acupuncture needle magazine 5 is provided with two needle outlet channels 51, two needle storage slots, and the two needle outlet channels 51 are arranged side by side. The two needle storage slots are respectively connected to the two needle outlet channels 51. Each of the two needle storage slots holds 25 acupuncture needles. The acupuncture needles are pressed towards the needle outlet channels 51 by elasticity. Only one acupuncture needle can be placed in the needle outlet channel 51. That is, as soon as one acupuncture needle in the needle outlet channel 51 is pushed out, the next acupuncture needle will be pushed into the needle outlet channel 51 to fill it. The needle pusher 23 is located on one side of the center line of the mounting groove 41 and is aligned with one of the needle outlet channels 51. When the needle pusher 23 is pressed successively, the acupuncture needles in one needle outlet channel 51 can be ejected one by one. After the acupuncture needles in one needle outlet channel 51 are used up, the acupuncture needle magazine 5 is pulled out from the mounting groove 41, rotated 180 degrees and put back into the mounting groove 41 for fixation, so as to continue continuous acupuncture use.

[0047] In this embodiment, the continuous acupuncture device includes a toggle 6. One end of the toggle 6 is fixedly connected to one side of the gear adjustment component 1, and the other end of the toggle 6 protrudes out of the housing 4. When adjusting the gear of the needle ejection assembly 2, the toggle 6 can be manually toggle, so that the gear adjustment component 1 rotates inside the housing 4 to adjust to the appropriate gear.

[0048] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
