DETAILED DESCRIPTION

[0047] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0048] This embodiment provides a continuous needle removal device, which can realize continuous output of needles and thus assist the user in completing acupuncture treatment of the patient.

[0049] Before introducing this solution, a brief description of the needle structure is given here. Referring to Figure 1, the needle can be divided into a needle tip 101 and a needle handle 102. The diameter of the needle handle 102 is larger than the diameter of the needle tip 101. When performing the acupuncture operation, the user generally holds the needle handle 102 with his fingers and inserts the needle tip 101 into the patient's skin by twisting the needle.

[0050] The continuous needle removal device in this solution is designed based on the above-mentioned needles. Multiple needles can be placed in the continuous needle removal device of this solution in advance. During the specific operation, the user can easily perform the needle removal operation and insert the needles into the patient's skin to complete the acupuncture treatment.

[0051] In order to better understand the structural composition of this device, the continuous needle removal device mentioned in this solution is introduced in detail below.

[0052] In a specific embodiment of this scheme, referring to FIG2 , the continuous needle removal device includes a pressing portion 200 and a needle box portion 300 ; a plurality of single needles are placed in the needle box portion 300 , and by operating the pressing portion 200 , the continuous needle removal action of the single needles can be achieved.

[0053] Specifically, the pressing part 200 includes a striker 201 and a shell assembly; the striker 201 is fixed on the shell assembly; specifically, the striker 201 is fixedly connected to the edge of the shell assembly, the shell assembly has a central axis, and the striker 201 also has a central axis, and the central axis of the striker 201 is parallel to the central axis of the shell assembly.

[0054] The tail end of the needle box portion 300 is located in the housing assembly. It can be understood that a portion of the needle box portion 300 is installed in the pressing portion 200, and the other portion is outside the pressing portion 200; the needles are neatly arranged and installed in the range where the needle box portion 300 is connected to the pressing portion 200. For the convenience of the following description, the structure formed by multiple single needles arranged in sequence is defined as a needle group 100, and the needle group 100 is specifically housed in the needle box portion 300.

[0055] At the same time, a needle propulsion unit 400 is installed in the needle box unit 300. The function of the needle propulsion unit 400 is to push the needles in the needle group 100 to be fed one by one; specifically, the needle propulsion unit 400 has elastic potential energy, and the elastic potential energy of the needle propulsion unit 400 acts on the needle group 100, so that the single needle at the front end of the needle group 100 is always pushed to face the striker 201; the operating pressing unit 200 is axially moved relative to the needle box unit 300, so that the striker 201 abuts against the facing single needle until the single needle is pushed out and inserted into the patient's body.

[0056] In this embodiment, the needle pusher 400 is specifically installed in the needle box 300 and cooperates with the needle box 300 to achieve the continuous insertion of the individual needles in the needle set 100. Finally, under the impact of the striker 201, the single needle at the front end of the needle set 100 can be ejected. Therefore, in the following introduction, the components and structures of the needle pusher 400 and the needle box 300 are first explained to facilitate the understanding of the operating principle between the two, and finally the pressing portion 200 is introduced separately.

[0057] Specifically, referring to Figures 3 to 9, the needle propulsion unit 400 includes a needle pushing wheel platform 410 and a steel coil 420; and the needle box part 300 includes a needle outlet needle box 310; in the assembly structure, the needle pushing wheel platform 410 is docked with the tail end of the needle outlet needle box 310, and the needle pushing wheel platform 410 is coaxial with the needle outlet needle box 310; the needle pushing wheel platform 410 has a needle pushing boss 411 extending outward; at the tail end of the needle outlet needle box 310, there is a C-shaped countersunk blind groove 311, and one end of the countersunk blind groove is formed with a needle outlet hole 315 that passes through the needle outlet needle box 310, and the needle outlet hole 315 is connected to the countersunk blind groove 311 as a whole; the needle group 100 is arranged in sequence in the countersunk blind groove 311.

[0058] The needle group 100 is arranged in a hanging manner in the countersunk blind groove 311, because the structure of each needle includes a needle tip 101 and a needle handle 102, and the diameter of the needle handle 102 is larger than the needle tip 101. The countersunk structure of the countersunk blind groove 311 is mainly used to limit the needle handle 102, that is, the spatial gap of the countersunk blind groove 311 just allows the needle tip 101 of the needle to pass through, but the countersunk structure of the countersunk blind groove 311 can also limit the needle handle 102 of the needle. Therefore, the needle is placed in the countersunk blind groove 311 here in a hanging shape. The purpose of this design is to ensure that the bottom of the entire needle group 100 does not contact and generate friction with the needle box. Under the action of the needle pushing wheel 410, it can move smoothly, and the diameter of the needle outlet hole 315 is larger than the needle handle 102, so the needle can be smoothly removed.

[0059] The function of the steel coil 420 is to provide an elastic driving force for the needle wheel platform 410; specifically, the steel coil 420 is clamped between the needle wheel platform 410 and the needle box 310, and the steel coil 420 is a winding structure and has elastic potential energy; the wound steel coil 420 is installed between the needle wheel platform 410 and the needle box 310, and the two ends of the steel coil 420 are fixed to the needle wheel platform 410 and the needle box 310 respectively, so that under the action of the rebound force of the steel coil 420, the needle wheel platform 410 will be moved relative to the needle box 310 along the The shaft rotates (in FIG5 , the rotation direction of the needle-pushing wheel platform 410 is counterclockwise); the needle-pushing boss 411 on the needle-pushing wheel platform 410 always abuts against the single needle at the end of the needle group 100; therefore, as long as the needle-pushing wheel platform 410 rotates, the single needle at the front end of the needle group 100 is always located directly above the needle outlet hole under the push of the needle-pushing boss 411, waiting for the next action of the striker 201 in the pressing part 200, and at the same time, the needle is squeezed by the needle-pushing boss 411, and the needle will not fall from the needle outlet hole 315.

[0060] In this solution, the needle group 100 is placed in the countersunk blind groove 311, and the countersunk blind groove 311 is C-shaped. Therefore, after the countersunk blind groove 311 is full of needles, the formed needle group 100 will eventually be C-shaped; when the needles in the needle group 100 are output one by one, the needle pushing boss 411 will rotate one circle; in order to ensure that the steel coil 420 can always maintain efficient rebound potential energy, a limiting boss 312 extending toward the needle pushing wheel platform 410 is also provided at the tail end of the needle box 310; the limiting boss 312 corresponds to the needle pushing boss 411, and is mainly used to limit the needle pushing boss 411 from rotating one circle; at the same time, the position of the limiting boss 312 corresponds to the position of the C-shaped countersunk blind groove 311 and the needle outlet hole 315, so that all the needles of the needle group can be pushed by the needle pushing boss 411.

[0061] That is, the needle pushing boss 411 pushes the needle group 100 until all the needles in the needle group 100 are output. Then, the needle pushing boss 411 will be blocked by the limiting boss 312 and cannot rotate for the second circle. The needle pushing boss 411 can only be pushed back to its original position and then the needles can be rearranged in the countersunk blind groove 311.

[0062] The above structure can effectively ensure the elastic effect of the steel coil 420, and avoid the reduction of the elastic potential energy accumulated in the steel coil 420 after the push needle boss 411 rotates continuously, which affects the feeding effect of the needles in the device.

[0063] Optionally, the needle pusher platform 410 has an outwardly convex three-step structure, and the third step of the needle pusher platform 410 has a first bayonet 412, the needle box 310 has an inwardly concave step structure corresponding to the needle pusher platform 410, and the needle box 310 has a second bayonet 313; the steel coil 420 is sleeved on the third step and the innermost end of the steel coil 420 is fixed to the first bayonet 412; the outermost end of the steel coil 420 is fixed to the second bayonet 313.

[0064] The pin pusher wheel platform 410 is designed as a three-step ladder structure, the main purpose of which is to better install the steel coil 420. The steel coil 420 is mounted on the third step, which is more conducive to shaping the steel coil 420 and avoiding loose deformation of the steel coil 420 during subsequent use; and the setting of the first bayonet and the second bayonet 313 enables the steel coil 420 to be better clamped with the pin pusher wheel platform 410 and the needle box 310; compared with the method of fixing the steel coil 420 to the pin pusher wheel platform 410 and the needle box 310, the clamping structure is more flexible, and when the steel coil 420 is fatigued, it can be convenient to disassemble and replace the new steel coil 420.

[0065] The needle box part 300 in this solution also includes a needle box cover 320, which has a C-shaped through slot 321, and the through slot 321 corresponds to the countersunk blind slot 311 introduced above; when installed, the needle box cover 320 is fitted with the needle push wheel platform 410, and the needle box cover 320 is fixed to the needle outlet needle box 310, so that the tail of the needle group 100 is located in the through slot 321; the through slot 321 is a countersunk structure; at the same time, the countersunk part of the through slot 321 is covered with a C-shaped cover plate 322. When the needle is installed, the needle passes through the through slot 321 and is placed in the countersunk blind slot 311, and the cover plate 322 prevents the needle from falling.

[0066] Optionally, the fixation between the needle box cover 320 and the needle outlet needle box 310 includes alignment and locking; specifically, the needle box cover 320 also has a four-claw flange 323; the needle outlet needle box 310 has a locking position 314 corresponding to the four-claw flange; the four-claw flange 323 passes through the needle push wheel platform 410 and is locked and fixed with the locking position 314 to prevent the needle box cover 320 and the needle outlet needle box 310 from rotating relative to each other; and there are four bolt positions 324 on the needle box cover 320, and there are also four bolt holes 316 on the needle outlet needle box 310, and the fastening bolts 325 pass through the bolt positions 324 and are fixed to the bolt holes 316, and the needle box cover 320, the needle push wheel platform 410, the steel coil 420 and the needle outlet needle box 310 are formed into the needle box part 300 by fastening the bolts 325.

[0067] It is not difficult to understand at this point that the needle box cover 320 is fixed to the needle box 310, and the needle pusher wheel 410 can rotate between the needle box cover 320 and the needle box 310 under the action of the steel coil 420; that is, the needle box cover 320 and the needle box 310 limit the axial movement of the needle pusher wheel 410, but the needle pusher wheel 410 can rotate along the axis to push the needle group 100.

[0068] When the frontmost needle in the needle set 100 is above the needle exit hole 315, the user operates the pressing portion 200, so that the striker 201 in the pressing portion 200 moves axially and strikes the needle here, thereby striking the needle into the needle exit hole 315 until the needle comes out of the needle exit hole 315 of the needle box 310 and pierces the patient's skin.

[0069] In order to make the pressing part 200 more effective, the composition of the shell assembly is designed here. Specifically, referring to Figures 10-15, the shell assembly includes a tail cover 202, a shell body 203, a limit platform 204, a spring 205, a limit cover 206, a guide rod 207 and a fine-tuning column 208.

[0070] The specific connection structure is as follows: the striker 201 is fixed to the tail cover 202; the housing body 203 and the tail cover 202 are fixed by screws; the fine-tuning column 208 is threadedly connected to the tail cover 202; the guide rod 207 has a head and a rod; the rod of the guide rod 207 passes through the limit platform 204, and the spring 205 is threadedly connected to the fine-tuning column 208; the spring 205 is sleeved on the guide rod 207, and the head of the guide rod 207 is restricted from passing through the limit platform 204; The tail cover 202, the shell body 203, the limit platform 204, the spring 205, the guide rod 207 and the fine-tuning column 208 together constitute the pressing part 200; and the inner diameter of the tail of the limit cover 206 is smaller than the outer diameter of the needle box cover 320. The limit cover 206 is introduced from the needle box 310 and is threadedly connected to the shell body 203. When the tail of the limit cover 206 abuts against the needle box cover 320, the pressing part 200 and the needle box part 300 are connected together.

[0071] It can be understood that the shell body 203 in the pressing part 200 is mounted on the needle box cover 320, and the limiting cover 206 is threadedly installed at the front end of the shell body 203, and the limiting cover 206 is against the needle box cover 320, thereby ensuring the stability of the connection between the pressing part 200 and the needle box part 300.

[0072] The specific method of use is to point the needle outlet 315 of the device at the part of the patient that needs acupuncture, and the user presses down the pressing part 200 with force. At this time, the shell body 203 of the pressing part 200 moves axially downward relative to the needle box part 300, and the spring 205 in the pressing part 200 is compressed to accumulate elastic potential energy. At the same time, the striker 201 in the pressing part 200 will hit the opposite puncture needle, and continue to press until the puncture needle is inserted into the patient's skin; after the acupuncture is completed, the user releases the pressing part 200, the spring 205 in the pressing part 200 rebounds, and the shell body 203 resets axially relative to the needle box part 300 until it stops when the limit cover 206 abuts against the needle box cover 320. Of course, when the entire pressing portion is reset and rebounded, after the firing pin 201 is separated from the needle outlet hole 315, the needle group 100 in the needle box portion 300 is reloaded under the push of the needle pushing wheel 410, so that a needle is located directly above the needle outlet hole 315, waiting for the next action of the firing pin 201, and the cycle continues.

[0073] In order to allow the guide rod 207 to move smoothly when pressed, the needle box cover 320 is further provided with an avoidance position 326.

[0074] When the entire device is used to perform acupuncture on a patient, each time the user operates the pressing portion 200, a needle will be inserted into the patient's skin; continuous pressing will achieve continuous acupuncture at different locations on the patient's body, which is efficient and convenient.

[0075] Optionally, in order to ensure that the shell body 203 moves smoothly in the axial direction relative to the needle box part 300, a guide rail 2031 is further provided on the inner side wall of the shell body 203; the guide rail extends along the axial direction of the shell body 203; the outer wall of the limit platform 204 is provided with a first guide groove 2041, and the outer wall of the needle box cover 320 is provided with a second guide groove 3201; the guide rail 2031 is assembled in the first guide groove 2041 and the second guide groove 3201; when the shell body 203 moves in the axial direction relative to the needle box part 300, it also moves relative to the limit platform 204 and the needle box cover 320. At this time, the guide rail 2031 moves along the first guide groove 2041 and the second guide groove 3201. Therefore, during assembly, the needle box cover 320 and the limit platform 204 need to be accurately aligned.

[0076] Taking into account that different patients have different acupuncture needs, especially regarding changes in acupuncture depth, the present invention provides a fine-tuning column 208 with scales marked along the axis. Because the fine-tuning column 208 is connected to the tail cover 202 in a threaded connection, the fine-tuning column 208 can be rotated during use. The rotation of the fine-tuning column 208 will drive the adjustment of the guide rod 207, ultimately adjusting the distance between the limit platform 204 and the tail cover 202, so that the striker 201 is closer or farther away from the facing needle. In this way, when the needle is struck, the needle can be inserted deeper or shallower. It can be understood that adjusting the fine-tuning column 208 here can achieve the adjustment of the acupuncture depth, and marking the scale on the fine-tuning column 208 can allow the user to adjust and control it more accurately.

[0077] At this point, the above introduction to the specific structure of this device is completed; the specific assembly steps of the device are as follows:

[0078] In this solution, the assembly method can be divided into two large modules, that is, the pressing part 200 and the needle box part 300 can be assembled separately without affecting each other. Finally, under the action of the limiting cover 206, the pressing part 200 and the needle box part 300 are connected.

[0079] For the assembly sequence of the needle box portion 300, see Figures 3 to 9:

[0080] Step 1: Sleeve the steel coil 420 onto the third step of the needle pusher wheel 410, and secure the innermost end of the steel coil 420 to the first bayonet; secure the outermost end of the steel coil 420 to the second bayonet 313; then install the steel coil 420 and the needle pusher wheel 410 into the needle box 310 at the same time;

[0081] Step 2: Install the needle box cover 320. The four claw flanges 323 of the needle box cover 320 pass through the needle push wheel platform 410 and are fixed to the clamping position 314 in the needle box 310. The fastening bolts 325 pass through the four bolt positions 324 and are screwed into the four bolt holes 316 on the needle box 310, so that the needle box cover 320 is fixed to the needle box 310.

[0082] Step 3: Manually rotate the push pin boss 411 to cause the steel coil 420 to contract and store force;

[0083] Step 4: The needle assembly 100 passes through the C-shaped through-slot on the needle box cover 320 and is placed into the C-shaped countersunk blind slot 311. At this time, the needle handle 102 of the needle assembly 100 is located in the through-slot of the needle box cover 320. Release the needle pushing boss 411. Under the elastic force of the steel coil 420, the needle pushing boss 411 presses the needle assembly 100, applying pressure to the needle assembly 100 toward the needle outlet 315.

[0084] Fifth, close the cover 322.

[0085] For the assembly steps of the pressing portion 200, see Figures 10 and 11:

[0086] Step 1: Fix the firing pin 201 to the tail cover 202;

[0087] Step 2: Pass the rod portion of the guide rod 207 through the limit platform 204 and the spring 205, and thread it into the fine-tuning column 208; the fine-tuning column 208 is threaded into the tail cover 202;

[0088] Step 3: Assemble the shell body 203 and fix the shell body 203 and the tail cover 202 with screws. Before fixing, the guide rail 2031 on the inner wall of the shell body 203 needs to correspond to the first guide groove 2041 on the limit platform 204 and the second guide groove 3201 on the needle box cover 320.

[0089] 13-14, the pressing portion and the needle box portion are aligned and assembled, the limiting cover 206 is introduced from the needle box 310 until it is threadedly connected to the shell body 203. When the tail of the limiting cover 206 abuts against the needle box cover 320, the pressing portion 200 and the needle box portion 300 are connected to complete the assembly.

[0090] When the needles are used up and the needle box needs to be replaced, the limiting cover 206 can be screwed separately. As long as the limiting cover 206 is detached, the pressing part 200 and the needle box part 300 will be separated, and then the needle box part 300 containing the needles can be replaced; or the needle box part 300 can be removed, the cover plate 322 is punched, and the needle pushing boss 411 can be rotated in the opposite direction to install the needle.

[0091] This technical solution cleverly designs the structure of the needle removal device, and with the cooperation of the pressing part and the needle box part, can achieve continuous needle removal operation; that is, the user puts the prepared needle into the needle box part in advance, and when performing acupuncture on the patient, the needle removal action can be completed by operating the pressing part. Each time the pressing part in the device is pressed once, the needle operation will be performed; through the above structure, the tediousness caused by the traditional repeated needle removal is effectively avoided, and the convenience of the acupuncture process is effectively improved.

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
