Description

Technical Field

[0001] This invention relates to the field of electromyography acupuncture technology, and in particular to an electromyography acupuncture assembly system and method. Background Technology

[0002] The existing electromyography (EMG) needle tip bevel cannot be positioned, making it difficult for doctors to determine the direction of the bevel during operation, thus exacerbating patient pain. The current EMG needle body is connected to the conductor via crimping, which requires scraping off the insulating coating of the needle core with a blade before crimping. This is time-consuming and laborious, and can damage the needle core and may cause a break in the connection if not completely removed. During crimping, the needle body is subjected to force, posing the following risks: 1. Damage to the needle body causing short circuits or open circuits; 2. The needle body may tilt under force, causing it to be out of sync with the conductor; 3. Unstable and uneven crimping force leads to uncontrollable connection strength, affecting usability. Furthermore, the crimping process is complex, slow, and unsuitable for mass production. Summary of the Invention

[0003] This invention addresses the problems and shortcomings of existing technologies by providing a myoelectric needle assembly system and method.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This invention provides an electromyography needle assembly system, characterized in that it includes an operating table, on which a U-shaped frame with an opening facing downwards, a welding machine, and a control host are fixed. The bottom sides of the horizontal frame of the U-shaped frame are respectively provided with elongated positioning grooves along the length direction, so that the bottom sides of the horizontal frame form elongated slide rails. Each elongated slide rail is slidably fitted with a U-shaped electric slider. One end of each U-shaped electric slider is positioned in the corresponding elongated positioning groove, and the other end is fixedly connected to a large base plate, which is placed above the U-shaped frame.

[0006] The base plate is fixed with a myoelectric needle bevel positioning assembly, which includes a needle body fixing plate for fixing multiple needles. When each needle is fixed on the needle body fixing plate, the bevel of the needle tip always faces upward. The end of the needle body fixing plate near the needle tip is fixed with a bevel fixing plate, which abuts against the bevel of the needle tip. The end of the needle body fixing plate away from the needle tip is provided with a spring piece fixing plate for fixing spring pieces that match the needles one by one. The spring pieces are provided with a spring piece welding part and a spring piece slotting part. When the spring pieces are fixed on the spring piece fixing plate, the spring piece slotting part always faces upward, so that the bevel of the needle tip and the spring piece slotting part are in the same direction to identify the bevel direction. The spring piece fixing plate is connected to the needle body fixing plate, so that the needle passes through the center of the corresponding spring piece and is on the same axis. The welding head of the welding machine is located directly above the U-shaped frame.

[0007] The control host is used to control the electric slider to drive the large base plate and the electromyography needle inclined surface positioning component on it to slide along the long slide rail when the spring plate welding part of the first spring in the sliding direction is directly below the welding head, and control the welding machine to weld the spring plate welding part of each spring in sequence so that the needle body and the spring plate are welded together.

[0008] The present invention also provides a method for assembling electromyographic needles, characterized in that it utilizes the aforementioned electromyographic needle assembly system, and the method includes the following steps:

[0009] Step 1: Placing the needles: Multiple needles are fixed on the needle fixing plate. The bevel of the needle tip of each needle is always facing upwards, and the bevel of each needle tip is in contact with the bevel positioning plate.

[0010] Step 2, Placing the spring pieces: The spring piece fixing plate is fixed with spring pieces that match the needle body one by one. The slotted part of each spring piece always faces upward so that the bevel of the needle tip and the slotted part of the spring piece are in the same direction so as to identify the direction of the bevel.

[0011] Step 3: Needle body and spring sheet docking: The spring sheet fixing plate docks with the needle body fixing plate, so that the needle body passes through the center of the corresponding spring sheet and is on the same axis as it;

[0012] Step 4: Welding the needle body and the spring: When the control host receives the welding command, it controls the electric slider to drive the large base plate and the electromyography needle inclined surface positioning component on it to slide along the long slide rail. When the spring welding part of the first spring in the sliding direction is directly below the welding head, the electric slider is paused, and the welding machine is controlled to weld the spring welding parts of each spring in sequence so that the needle body and the spring are welded together.

[0013] The positive and progressive effects of this invention are as follows:

[0014] 1. The bevel of the electromyography needle tip is in the same direction as the groove of the spring, so that the direction of the bevel can be identified according to the groove of the spring, making it easier for doctors to determine the position of the bevel of the needle tip.

[0015] 2. The needle core no longer needs to have an insulating coating scraped off.

[0016] 3. By changing the crimping process to welding, the needle body is no longer subjected to force, thus solving the problems of short circuits or open circuits, needle body tilting, and uneven and unstable needle body force leading to uncontrollable connection firmness.

[0017] 4. By arranging products in a row, production efficiency can be greatly improved, whether by manual welding or automated machine welding. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figure 1-7 As shown, this embodiment provides an electromyography needle assembly system, which includes an operating table 1. A U-shaped frame 2 with its opening facing downward is fixed on the operating table 1. Long strip positioning grooves 3 are respectively opened on both sides of the bottom of the horizontal frame of the U-shaped frame 2 along the length direction, so that the bottom sides of the horizontal frame of the U-shaped frame 2 form long strip slide rails 4. Each long strip slide rail 4 is slidably equipped with a U-shaped electric slider 5. One end of each U-shaped electric slider 5 is positioned in the corresponding long strip positioning groove 3, and the other end is fixedly connected to a large base plate 6. The large base plate 6 is placed above the U-shaped frame 2. The U-shaped electric slider 5 is an existing component.

[0027] A myoelectric needle inclined plane positioning component 7 is fixed on the base plate 6; a vertical beam 8 is also fixed on the operating table 1, and a horizontal beam 9 is fixed on the vertical beam 8. The vertical beam 8 and the horizontal beam 9 are used to fix a welding machine containing a welding head 10. This is the prior art. The welding head 10 of the welding machine is located directly above the U-shaped frame 2; a control host 11 is also fixed on the operating table 1.

[0028] The electromyography needle inclined plane positioning assembly 7 includes a needle body fixing plate 71, an inclined plane fixing plate 72, and a spring plate fixing plate 73.

[0029] The needle fixing plate is used to fix multiple needles: Multiple needle slots 711 are evenly spaced along the longitudinal direction on the needle fixing plate 71. These needle slots 711 are arranged horizontally and parallel to each other. A needle 12 is embedded and fixed in each needle slot 711, and the inclined surface 121 of the needle tip on the needle 12 always faces upward.

[0030] Each needle body slot 711 is U-shaped, and the outer periphery of each needle body 12 protrudes 0.1 to 0.2 mm from the corresponding needle body slot 711. The groove width of each needle body slot 711 is 0.01 to 0.02 mm greater than the diameter of the needle body 12.

[0031] The inclined plate is used to position the inclined surface: the inclined plate 72 is fixed to the end of the needle body fixing plate 71 near the needle tip, that is, the front end of the needle body fixing plate 71, and the inclined plate 72 abuts against the inclined surface 121 of the needle tip.

[0032] The assembly relationship between the inclined fixing plate and the needle fixing plate is as follows: Symmetrical L-shaped fixing seats 712 are fixed on both sides of the surface of the needle fixing plate 71 near the needle tip. The left end of the inclined fixing plate 72 is placed inside the left-side L-shaped fixing seat 712 and secured by a bolt 713 passing through the top. The right end of the inclined fixing plate 72 is placed inside the right-side L-shaped fixing seat and secured by a bolt passing through the top. The inclined fixing plate 72 can be adjusted in its front-to-back position on the needle fixing plate 71 to accommodate different needle lengths. Furthermore, the rear end of the L-shaped fixing seat 712 can be sealed to prevent the inclined fixing plate 72 from exceeding the rear end of the L-shaped fixing seat 712 when its position is adjusted on the needle fixing plate 71.

[0033] The spring clip fixing plate is used to fix multiple spring clips: the spring clip fixing plate 73 is fixed to the end of the needle body fixing plate 71 away from the needle tip, i.e., the rear end of the needle body fixing plate 71. The spring clip fixing plate 73 has spring clip slots 731 evenly spaced along the longitudinal direction, corresponding one-to-one with the needle body slots 711. The axis of each needle body slot 711 corresponds one-to-one with the axis of the corresponding spring clip slot 731 to ensure their concentricity. These spring clip slots 731 are arranged laterally and are parallel to each other. Each spring piece 13 is embedded and fixed in each spring piece slot 731. The spring piece 13 matches the needle body 12 one by one. The spring piece 13 is provided with a spring piece welding part 131 and a spring piece slotting part 132. When the spring piece 13 is fixed on the spring piece fixing plate 73, the spring piece slotting part 132 always faces upward, so that the bevel 121 of the needle tip and the spring piece slotting part 132 are in the same direction, so that the bevel direction of the needle tip can be easily identified according to the direction of the spring piece slotting part 132.

[0034] The assembly relationship between the spring clip fixing plate and the needle body fixing plate is as follows: Positioning seats 714 are fixed to the left and right ends of the needle body fixing plate 71 at the end furthest from the needle tip (i.e., the rear end of the needle body fixing plate 71). The positioning seats 714 extend out of the needle body fixing plate 71. The spring clip fixing plate 73 is mated to the needle body fixing plate 71, and the spring clip fixing plate 73 is confined between the two positioning seats 714. The top of the spring clip fixing plate 73 is flush with the top of the needle body fixing plate 71, allowing the needle body 12 to pass through the center of the corresponding spring clip 13 and be on the same axis. A first magnetic fixing hole 715 is provided at the middle position of the end of the needle body fixing plate 71 furthest from the needle tip, and a first magnet 716 is installed in the first magnetic fixing hole 715. A second magnetic fixing hole 732 is provided at the middle position of the mating end of the spring clip fixing plate 73, and a second magnet 733 is installed in the second magnetic fixing hole 732. When the spring clip fixing plate 73 is aligned with the needle body fixing plate 71, the first magnet 716 and the second magnet 733 attract each other, thereby fixing the spring clip fixing plate 73 and the needle body fixing plate 71 together and preventing the spring clip fixing plate 73 from moving.

[0035] Furthermore, a needle core stop 734 is fixed at the rear end of each spring slot 731. When the spring fixing plate 73 is aligned with the needle body fixing plate 71, the needle body 12 passes through the center of the corresponding spring 13 and is on the same axis as it. The end of the needle core 122 on the needle body 12 exactly abuts against the corresponding needle core stop 734. The needle core stop 734 can both position the needle body 12 to prevent it from moving back and forth and detect whether the beveled surface of the needle tip has been positioned.

[0036] In this embodiment, the needle body slot 711 and the spring piece slot 731 are evenly arranged and have the same number. Multiple slots can be set to improve production efficiency, and generally 8 to 30 slots can be set.

[0037] The control host 11 is used to establish a coordinate system with the U-shaped frame 2 as the X-axis, the crossbeam 8 of the fixed welding machine as the Y-axis, and the vertical beam 9 of the fixed welding machine as the Z-axis, to mark the position of the welding head 10. The vertical spacing directly below the welding head 10 is marked as the set welding point.

[0038] After the needle body 12 and spring piece 13 on the electromyography needle inclined surface positioning component 7 are assembled, press the button on the control host 11 to issue a welding command. When the control host 11 receives the welding command, it controls the electric slider 5 to drive the base plate 6 and the electromyography needle inclined surface positioning component 7 on it to slide along the long slide rail 4. When the spring piece welding part 131 of the first spring piece in the sliding direction is located at the set welding point, the electric slider 5 is paused, and the welding head 10 of the welding machine is controlled to weld the spring piece welding part 131 of the first spring piece so that the first spring piece 13 is welded to the corresponding needle body 12. After the welding is completed, the assembled electromyography needle is formed. Then, the electric slider 5 is controlled to drive the base plate 6 and the electromyography needle inclined surface positioning component 7 on it to slide along the long slide rail 4 to set the left and right movement distance so that the spring piece welding part 131 of the next spring piece is located at the set welding point and welded by the welding head 10. In this way, each spring piece 13 can be welded to the corresponding needle body 12.

[0039] This embodiment also provides a method for assembling electromyographic needles, which utilizes the aforementioned electromyographic needle assembly system. The electromyographic needle assembly method includes the following steps:

[0040] Step 1: Placing the needles: Multiple needles 12 are fixed on the needle fixing plate 71. The bevel of the needle tip 121 of each needle 12 always faces upward, and the bevel of each needle tip 121 abuts against the bevel positioning plate 72.

[0041] Step 2, Placing the spring pieces: Spring pieces 13 that match the needle body 12 are fixed on the spring piece fixing plate 73. The spring piece groove 132 of each spring piece 13 always faces upward so that the bevel 121 of the needle tip and the spring piece groove 132 are in the same direction so as to identify the direction of the bevel.

[0042] Step 3: Needle body and spring piece docking: Spring piece fixing plate 73 docks with needle body fixing plate 71, so that needle body 12 passes through the center of the corresponding spring piece 13 and is on the same axis as it.

[0043] Step 4: Welding the needle body and the spring piece: When the host machine receives the welding command, it controls the electric slider 5 to drive the base plate 6 and the electromyography needle inclined surface positioning component 7 on it to slide along the long slide rail 4. When the spring piece welding part 131 of the first spring piece in the sliding direction is directly below the welding head 10, the electric slider 5 is paused and the welding machine is controlled to weld the spring piece welding part 131 of each spring piece in sequence so that the needle body 12 and the spring piece 13 are welded together.
