An acupoint catgut implantation device for catgut implantation and a method of using the same

Abstract

This invention relates to the field of acupoint embedding technology and discloses an embedding instrument and its usage method for acupoint embedding. The instrument includes a cannula, a needle fixedly connected to the outer wall of the cannula, a needle core slidably connected to the inner wall of the needle core, and a connecting tube connected to the inner wall of the central axis of the cannula. In this invention, medical personnel rotate a knob a certain number of turns, the clamping wheel moves, and the protein thread enters the connecting tube along the guide tube. Pressing a button causes the cutting head to move downwards, cutting the protein thread. Subsequently, the needle core is pushed towards the needle core, effectively preventing the problems encountered in clinical acupoint embedding operations where, due to the small diameter of both the needle and the thread, medical personnel manually insert the protein thread through the needle using medical tweezers. This process is prone to hand tremors, leading to inaccurate alignment and repeated needle insertion failures, prolonging the single-acupoint operation time and affecting the overall diagnostic and treatment efficiency.

Description

Technical Field

[0001] This invention relates to the field of acupoint embedding equipment technology, specifically to an embedding device for acupoint embedding and its usage method. Background Technology

[0002] Acupoint embedding involves inserting absorbable surgical sutures into the subcutaneous or muscle layer of acupoints using specialized needles. The sutures provide continuous physical stimulation and bio-absorption to the acupoints, achieving long-lasting effects such as unblocking meridians and harmonizing Qi and blood.

[0003] This traditional Chinese medicine therapy, which balances the functions of the internal organs, can provide stimulation for several weeks after a single treatment. It is a minimally invasive, long-lasting, and convenient modern acupuncture technique.

[0004] In clinical acupoint embedding procedures, because both the needle and the thread are relatively small in diameter, medical staff use medical tweezers to hold the protein thread and manually insert it through the needle. During the operation, hand tremors are likely to occur, which can easily lead to inaccurate alignment and repeated needle insertion failures, prolonging the operation time of a single acupoint and affecting the overall diagnostic and treatment efficiency. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an embedding device for acupoint embedding, including a cannula, a needle fixedly connected to the outer wall of the cannula, a needle core slidably connected to the inner wall of the center of the needle, and a connecting tube disposed at the inner wall of the central axis of the cannula, and further comprising:

[0006] The wire feeding mechanism is rotatably mounted on the inner wall of the sleeve;

[0007] The cutting mechanism is slidably disposed on the inner wall of the sleeve near the needle tip.

[0008] The limiting mechanism is fixedly installed inside the sleeve;

[0009] The connecting tube is connected to the needle, and the needle core slides on the inner wall of the needle and can also slide on the inner wall of the connecting tube. The needle core is used to move the protein thread. The needle pierces the subcutaneous fat layer of the human body, and the device embeds the protein thread into the fat layer to stimulate acupoints.

[0010] Preferably, the wire feeding mechanism includes:

[0011] The rotating assembly is rotatably disposed on the inner wall of the cannula on the side away from the needle.

[0012] The propulsion component is rotatably mounted on the inner wall of the sleeve near the rotating component.

[0013] The rotating component can drive the propulsion component to rotate during rotation, thereby pushing the protein thread towards the needle.

[0014] Preferably, the cutting mechanism includes:

[0015] The pressing component is slidably installed on the inner wall of the cannula near the needle tip;

[0016] The limiting component is fixedly installed inside the sleeve.

[0017] The limiting component limits the sliding stroke of the pressing component and provides reset power.

[0018] Preferably, the limiting mechanism includes:

[0019] Turntable assembly, the turntable assembly is fixedly mounted on the outer wall of the rotating assembly;

[0020] The push wire assembly is fixedly installed on the inner wall of the central axis of the sleeve;

[0021] The turntable assembly restricts the direction of movement of the rotating assembly, while the pusher assembly pushes the protein thread.

[0022] Preferably, the rotating assembly includes a connecting rod rotatably connected to the inner wall of the sleeve, a winding disc rotatably connected to the middle outer wall of the connecting rod, a friction wheel fixedly connected to the outer wall of the connecting rod, and a knob fixedly connected to the top outer wall of the connecting rod.

[0023] The winding reel has a limiting block at the bottom to prevent it from moving along the connecting rod. The reel is wound with protein thread, which can meet the protein thread consumption of one treatment course. The friction wheel is located on the side of the winding reel near the knob. The knob is located outside the sleeve and has a directional arrow.

[0024] Preferably, the propulsion assembly includes two connecting rods 2 rotatably connected to the inner wall of the sleeve near the connecting rod 1. Each of the two connecting rods 2 has a clamping wheel fixedly connected to its middle outer wall. Each of the two clamping wheels has a friction disc 2 fixedly connected to its side near the knob. A guide tube is provided on the outer wall of the connecting tube.

[0025] Among them, the two connecting rods are arranged in a mirror image, and the friction discs two close to the friction wheel one mesh with the friction wheel one. The two friction discs two mesh with each other, and the protein thread on the clamping wheel is inserted into the guide tube and clamped by the two clamping wheels. The material of the two clamping wheels is soft rubber.

[0026] Preferably, the pressing assembly includes a slide rod slidably connected to the inner wall of the sleeve, a button fixedly connected to the top of the slide rod, and a blade fixedly connected to the side of the slide rod away from the button;

[0027] The button extends outside the sleeve, and the end of the blade away from the slide bar is made into a sharp blade shape.

[0028] The limiting component includes a spring fixedly connected to the side of the cutter head near the button, a slot is provided on the outer wall of the connecting tube, and a fixing plate is fixedly connected to the inner wall of the sleeve;

[0029] The end of the spring furthest from the cutter head is fixedly connected to the sleeve. The spring is initially in a free state, and once the slot is disconnected, the entire connecting pipe is connected.

[0030] Preferably, the turntable assembly includes a limiting block fixedly connected to the outer wall of the sleeve, a turntable fixedly connected to the outer wall of the connecting rod near the knob, and a plurality of elastic heads fixedly connected to the outer wall of the turntable.

[0031] The limiting block is stepped, with a larger slope on one side and a smaller slope on the other. Several elastic heads are hook-shaped and arranged in a circular array. The material of the elastic heads is soft plastic.

[0032] Preferably, the pusher assembly includes a second slot formed on the outer wall of the connecting tube, and an elastic sleeve is fixedly connected to the outer wall of the needle core;

[0033] Among them, the second groove disconnects the entire connecting tube, and the elastic sleeve is fixed at the end of the needle core. The elastic sleeve is made of soft rubber.

[0034] A method for using a thread embedding device for acupoint embedding includes the following steps:

[0035] S1: Installation device: Medical staff remove the packaging, insert a portion of the needle core into the connecting tube, and then turn the knob a certain number of times to allow part of the protein thread to move along the guide tube into the connecting tube towards the needle. Then, press the pressing component to cut the protein thread, and then continue to push the needle core to expose a portion of the cut protein thread at the needle tip.

[0036] S2: Thread embedding: Insert the needle into the subcutaneous fat layer to a certain depth, rotate the cannula, and then continue to push the needle core. After the thread embedding is completed, pull out the needle and perform hemostasis.

[0037] S3: Re-implantation: After pulling out the needle, pull the needle core past the second slot, rotate the knob again, then press the pressing component to push the needle core to expose part of the protein thread, and perform the implantation operation again.

[0038] The present invention has the following beneficial effects:

[0039] (1) In this invention, medical staff first pull the needle core away from the needle tip, rotate the knob a certain number of times to drive the two friction discs to move, thereby driving the clamping wheel to move. The protein thread enters the connecting tube along the guide tube. After the knob is rotated a certain number of times, press the button to make the blade move downward to cut the protein thread. After cutting is completed, release the button and then push the needle core towards the needle tip. The elastic sleeve at the end of the needle core can push the cut protein thread towards the needle tip. Through the application of the above components, the problem of hand tremors during the operation of embedding threads at acupoints in clinical practice is effectively prevented. Since the diameter of both the needle tip and the thread is small, medical staff have to use medical tweezers to hold the protein thread and manually insert it from the needle tip. During the operation, the hand is prone to tremors, which can easily lead to inaccurate positioning and repeated needle insertion failures, prolonging the operation time of a single acupoint and affecting the overall diagnostic and treatment efficiency.

[0040] (2) This invention utilizes the feature of the above-mentioned device to rotate the knob for threading. When the medical staff rotates the knob clockwise, the curved part on the back of the elastic head is squeezed by the side of the limiting block with a smaller slope, and the elastic head contracts in the direction of the connecting rod, so that the turntable can rotate normally clockwise. When the turntable rotates counterclockwise, the tip of the elastic head is blocked by the side of the limiting block with a larger slope, thereby restricting the counterclockwise rotation of the turntable. This ensures that when the medical staff rotates the knob, they can only rotate clockwise, preventing the medical staff from not being able to distinguish the direction and rotating in the wrong direction. Through the application of the above-mentioned components, the problem of medical staff rotating the knob incorrectly, causing the protein thread to fall off the clamping wheel and making it impossible to perform subsequent threading operations is effectively prevented.

[0041] (3) This invention utilizes the characteristics of the above-mentioned device needle core pushing protein thread. An elastic sleeve is fixedly connected to the end of the needle core. When the elastic sleeve is pushed towards the needle tip, the gap between the elastic sleeve and the connecting tube is difficult for the protein thread to get stuck. Even if the protein thread gets stuck in the gap due to its small diameter, the needle core is pulled back a certain distance. The deformation at the contact point between the elastic sleeve and the connecting tube intensifies. At this time, the distance from the contact point between the elastic sleeve and the connecting tube to the fixed end of the elastic sleeve will produce a small indentation in the direction of the needle core axis. The gap at the stuck position will increase, so that the protein thread can be pulled out from the gap and the needle core can continue to push the protein thread to move. Through the application of the above components, the problem of the protein thread getting stuck in the gap between the needle core and the connecting tube during the needle core pushing process is effectively prevented.

[0042] (4) This invention utilizes the characteristic of the above-mentioned device to pull the needle core, pulling the needle core away from the needle tip. When the elastic sleeve moves to a position of the groove, the elastic sleeve is restricted by the groove and folds over, becoming as follows. Figure 8 In the G-state, when the needle core moves to the connection position between the connecting tube and the guide tube, it ensures that the uncut protein thread remains close to the guide tube and does not enter the connecting tube. The elastic sleeve contacts the connecting tube at slot two. As the needle core continues to move, the elastic sleeve moves from... Figure 8 The state of G in the middle becomes as follows Figure 11 In the K-mode, the application of the above components effectively prevents the problem of uncut protein threads being bent by the needle core during the pushing and pulling process, making it difficult to advance the protein threads.

[0058] 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, and 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.

[0059] Example 1, please refer to Figure 1 - Figure 6 This invention relates to a thread embedding device for acupoint embedding, comprising a sleeve 13, a needle 14 fixedly connected to the outer wall of the sleeve 13, a needle core 15 slidably connected to the inner wall of the center of the needle 14, and a connecting tube 16 communicating with the inner wall of the central axis of the sleeve 13, and further comprising:

[0060] The wire feeding mechanism 1 is rotatably mounted on the inner wall of the sleeve 13;

[0061] Cutting mechanism 2 is slidably disposed on the inner wall of sleeve 13 near the needle 14.

[0062] Limiting mechanism 3 is fixedly installed inside sleeve 13;

[0063] The connecting tube 16 is connected to the needle 14. The needle core 15 slides on the inner wall of the needle 14 and can also slide on the inner wall of the connecting tube 16. The needle core 15 is used to push the movement of the protein thread. The needle 14 pierces the subcutaneous fat layer of the human body. The device embeds the protein thread into the fat layer to stimulate acupoints.

[0064] The wire feeding mechanism 1 includes:

[0065] Rotating assembly 11 is rotatably disposed on the inner wall of the sleeve 13 on the side away from the needle 14;

[0066] The propulsion component 12 is rotatably disposed on the inner wall of the sleeve 13 near the rotating component 11.

[0067] The rotating component 11 can drive the propulsion component 12 to rotate during the rotation process, thereby pushing the protein thread towards the needle 14.

[0068] Cutting mechanism 2 includes:

[0069] Pressing component 21 is slidably installed on the inner wall of the sleeve 13 near the needle 14.

[0070] Restriction component 22 is fixedly disposed inside the sleeve 13;

[0071] The limiting component limits the sliding stroke of the pressing component and provides reset power.

[0072] Limiting mechanism 3 includes:

[0073] Turntable assembly 31 is fixedly mounted on the outer wall of rotating assembly 11;

[0074] The push wire assembly 32 is fixedly installed on the inner wall of the central axis of the sleeve 13;

[0075] The turntable assembly 31 restricts the movement direction of the rotating assembly 11, and the pusher assembly 32 pushes the protein thread.

[0076] Example 2, please refer to Figure 3 - Figure 12 The present invention is an acupuncture point embedding device. Based on the first embodiment, the rotating component 11 includes a connecting rod 111 rotatably connected to the inner wall of the sleeve 13, a winding disc 112 rotatably connected to the middle outer wall of the connecting rod 111, a friction wheel 113 fixedly connected to the outer wall of the connecting rod 111, and a knob 114 fixedly connected to the top outer wall of the connecting rod 111.

[0077] Among them, the bottom of the winding reel 112 has a limiting block to prevent the winding reel 112 from moving along the connecting rod 111. The winding reel 112 is wound with protein thread, which can meet the protein thread consumption of one treatment course. The friction wheel 113 is located on the side of the winding reel 112 near the knob 114. The knob 114 is located outside the sleeve 13 and has a directional arrow.

[0078] The propulsion assembly 12 includes two connecting rods 121 rotatably connected to the inner wall of the sleeve 13 near the connecting rod 111. The middle outer wall of each of the two connecting rods 121 is fixedly connected to a clamping wheel 122. The two clamping wheels 122 are fixedly connected to a friction disc 123 near the knob 114. The outer wall of the connecting pipe 16 is connected to a guide pipe 124.

[0079] Among them, the two connecting rods 121 are arranged in a mirror image, and the friction disc 123 close to the friction wheel 113 meshes with the friction wheel 113. The two friction discs 123 mesh with each other, and the protein thread on the clamping wheel 122 is inserted into the guide tube 124 and clamped by the two clamping wheels 122. The material of the two clamping wheels 122 is soft rubber.

[0080] The pressing assembly 21 includes a slide rod 211 slidably connected to the inner wall of the sleeve 13, a button 212 fixedly connected to the top of the slide rod 211, and a blade 213 fixedly connected to the side of the slide rod 211 away from the button 212.

[0081] Among them, the button 212 extends out of the sleeve 13, and the end of the blade 213 away from the slide bar 211 is made into a sharp blade shape;

[0082] The limiting component 22 includes a spring 221 fixedly connected to the side of the blade 213 near the button 212, a slot 222 is opened on the outer wall of the connecting tube 16, and a fixing plate 223 is fixedly connected to the inner wall of the sleeve 13.

[0083] Among them, the end of spring 221 away from the cutter head 213 is fixedly connected to sleeve 13. The initial state of spring 221 is free state, and slot 1 222 disconnects the entire connecting pipe 16.

[0084] After removing the needle 14, the medical staff first pulls the needle core 15 away from the needle 14. When the elastic sleeve 322 at the end of the needle core 15 passes the groove 321, the knob 114 is rotated a certain number of times. Figure 5As shown, when knob 114 is rotated clockwise, it drives friction wheel 113 and winding reel 112 on connecting rod 111 to rotate clockwise. Friction disc 123 near connecting rod 111 meshes with friction wheel 113, thereby driving friction disc 123 near connecting rod 111 to rotate counterclockwise. The two friction discs 123 mesh, thereby driving friction disc 123 away from connecting rod 111 to rotate clockwise. The movement of the two friction discs 123 drives clamping wheel 122 to move. The protein thread held by the two clamping wheels 122 can move to the right, and the protein thread on winding reel 112 is pulled and continuously reduced. The protein thread is pushed by the two clamping wheels 122 along guide tube 124 into connecting tube 16. After knob 114 is rotated a certain number of times, button 212 is pressed to move slide bar 211 downward. The movement causes the blade 213 to move downwards, thereby causing the spring 221 to change from a free state to a stretched state. The blade 213 moves downwards and contacts the protein thread inside the connecting tube 16. The sharp end of the blade 213 cuts the protein thread. When the blade 213 fully contacts the fixing plate 223, the cutting is completed. The button 212 is released, and the elastic potential energy stored in the spring 221 is released, changing from a stretched state to a free state. The blade 213 moves upwards and then pushes the needle core 15 towards the needle head 14. When the end of the needle core 15 reaches the slot 222, the elastic sleeve 322 at the end of the needle core 15 can push the cut protein thread towards the needle head 14. Continue to push the needle core 15 until part of the cut protein thread is exposed from the needle head 14. Stop pushing and insert the needle head 14 into the subcutaneous fat layer of the human body for thread embedding.

[0085] The turntable assembly 31 includes a limiting block 311 fixedly connected to the outer wall of the sleeve 13, and a turntable 312 fixedly connected to the outer wall of the connecting rod 111 near the knob 114. Several elastic heads 313 are fixedly connected to the outer wall of the turntable 312.

[0086] Among them, the limiting block 311 is stepped, with a larger slope on one side and a smaller slope on the other side. Several elastic heads 313 are hook-shaped and arranged in a circular array. The material of the elastic heads 313 is soft plastic.

[0087] When medical staff turn knob 114 clockwise, as Figure 6 As shown, the connecting rod 111 is rotated clockwise by the knob 114, causing the turntable 312 to rotate clockwise as well. During this time, the elastic head 313, near the limiting block 311, remains in contact with the limiting block 311 and undergoes slight deformation. When rotating clockwise, the curved back of the elastic head 313 is pressed by the side of the limiting block 311 with a smaller slope, causing the elastic head 313 to contract towards the connecting rod 111, thus allowing the turntable 312 to rotate clockwise normally. When the turntable 312 rotates counterclockwise, the tip of the elastic head 313 presents an angle as shown in the image. Figure 6In the middle H state, the tip of the elastic head 313 is blocked by the slope of the limiting block 311, thereby restricting the turntable 312 from rotating counterclockwise. This ensures that when medical staff rotate the knob 114, they can only rotate clockwise, preventing them from being unable to distinguish the direction and rotating in the wrong direction.

[0088] The push wire assembly 32 includes a slot 321 opened on the outer wall of the connecting tube 16, and an elastic sleeve 322 is fixedly connected to the outer wall of the needle core 15.

[0089] Among them, the second slot 321 disconnects the entire connecting tube 16, and the elastic sleeve 322 is fixed at the end of the needle core 15. The elastic sleeve 322 is made of soft rubber.

[0090] An elastic sleeve 322 is fixedly connected to the end of the needle core 15. When the elastic sleeve 322 is pushed towards the needle tip 14, the elastic sleeve 322 will present the following shape. Figure 11 In state K, the elastic sleeve 322 is affected by its own elasticity. Both sides of the elastic sleeve 322 contact the inner wall of the connecting tube 16, and the end of the elastic sleeve 322 fixed on the needle core 15 does not contact the connecting tube 16. When the elastic sleeve 322 passes through the slot 222 and pushes the cut protein thread towards the needle 14, the gap between the elastic sleeve 322 and the connecting tube 16 is difficult to trap the protein thread. Even if the protein thread is trapped in the gap due to its small diameter, the needle core 15 is retracted a certain distance, and the deformation at the contact point between the elastic sleeve 322 and the connecting tube 16 intensifies. At this time, the distance from the contact point between the elastic sleeve 322 and the connecting tube 16 to the fixed end of the elastic sleeve 322 will produce a slight indentation in the direction of the axis of the needle core 15. The gap at the position where the thread is trapped will increase, so that the protein thread can be withdrawn from the gap, and the needle core 15 can continue to push the protein thread to move.

[0091] A method for using a thread embedding device for acupoint embedding includes the following steps:

[0092] S1: Installation device: Medical staff remove the packaging, insert the needle core 15 into a part of the connecting tube 16, and then turn the knob 114 a certain number of turns to make part of the protein thread enter the connecting tube 16 along the guide tube 124 and move towards the needle 14. Then press the pressing component 21 to cut the protein thread, and then continue to push the needle core 15 to make the cut protein thread protrude a part of the needle 14.

[0093] S2: Perform suture embedding: Insert the needle 14 into the subcutaneous fat layer of the human body to a certain depth, rotate the cannula 13, and then continue to push the needle core 15. After the suture embedding is completed, pull out the needle 14 and perform hemostasis.

[0094] S3: Re-implanting: After pulling out the needle 14, pull the needle core 15 past the slot 321, rotate the knob 114 again, then press the pressing component 21 to push the needle core 15 to expose part of the protein thread, and perform the implantation operation again.

[0095] One specific application of this embodiment is as follows: during use, the needle core 15 slides on the inner wall of the needle tip 14 and can also slide on the inner wall of the connecting tube 16. The needle core 15 is used to push the protein thread to move. The needle tip 14 pierces the subcutaneous fat layer of the human body. The device embeds the protein thread into the fat layer to stimulate acupoints of the human body. Then the needle tip 14 is pulled out to perform hemostasis.

[0096] After removing the needle 14, the medical staff first pulls the needle core 15 away from the needle 14. When the elastic sleeve 322 at the end of the needle core 15 passes the groove 321, the knob 114 is rotated a certain number of times. Figure 5 As shown, when knob 114 is rotated clockwise, it drives friction wheel 113 and winding reel 112 on connecting rod 111 to rotate clockwise. Friction disc 123 near connecting rod 111 meshes with friction wheel 113, thereby driving friction disc 123 near connecting rod 111 to rotate counterclockwise. The two friction discs 123 mesh, thereby causing friction disc 123 away from connecting rod 111 to rotate clockwise. The movement of the two friction discs 123 drives clamping wheel 12. 2. Movement: The protein thread held by the two clamping wheels 122 can move to the right, pulling the protein thread on the winding reel 112, continuously reducing its size. The protein thread is pushed by the two clamping wheels 122 along the guide tube 124 into the connecting tube 16. After the knob 114 is rotated a certain number of times, pressing the button 212 causes the slide bar 211 to move downward, driving the cutter head 213 downward, thereby causing the spring 221 to change from a free state to a stretched state. The cutter head 213 moves downward and contacts the protein thread in the connecting tube 16. The sharp end of the head 213 cuts the protein thread. When the head 213 fully contacts the fixing plate 223, the cutting is complete. Releasing the button 212 releases the stored elastic potential energy of the spring 221, causing it to transition from a stretched state to a free state. The head 213 moves upward, subsequently pushing the needle core 15 towards the needle head 14. When the end of the needle core 15 reaches the slot 222, the elastic sleeve 322 at the end of the needle core 15 pushes the cut protein thread towards the needle head 14, continuing to push... The needle core 15 is pushed until a portion of the cut protein thread is exposed above the needle tip 14. Then, the needle tip 14 is inserted into the subcutaneous fat layer for thread embedding. The application of the above components effectively prevents the problems that occur during clinical acupoint embedding operations. Due to the small diameter of both the needle tip 14 and the thread, medical staff have to use medical tweezers to hold the protein thread and manually insert it through the needle tip 14. During the operation, hand tremors are likely to occur, which can easily lead to inaccurate alignment and repeated needle insertion failures, prolonging the operation time of a single acupoint and affecting the overall diagnostic and treatment efficiency.

[0097] Utilizing the feature of the aforementioned device that allows for online connection by rotating knob 114, when medical staff rotate knob 114 clockwise, as... Figure 6As shown, the connecting rod 111 is rotated clockwise by the knob 114, causing the turntable 312 to rotate clockwise as well. During this time, the elastic head 313, near the limiting block 311, remains in contact with the limiting block 311 and undergoes slight deformation. When rotating clockwise, the curved back of the elastic head 313 is pressed by the side of the limiting block 311 with a smaller slope, causing the elastic head 313 to contract towards the connecting rod 111, thus allowing the turntable 312 to rotate clockwise normally. When the turntable 312 rotates counterclockwise, the tip of the elastic head 313 presents an angle as shown in the image. Figure 6 In the middle H state, the tip of the elastic head 313 is blocked by the steep slope of the limiting block 311, thereby restricting the turntable 312 from rotating counterclockwise. This ensures that when medical staff rotate the knob 114, they can only rotate clockwise, preventing them from being unable to distinguish the direction and rotating in the wrong direction. Through the application of the above components, the problem of medical staff accidentally rotating the knob 114, causing the protein thread to detach from the clamping wheel 122 and making it impossible to perform subsequent threading operations, is effectively prevented.

[0098] Utilizing the characteristic of the needle core 15 of the aforementioned device to push the protein thread, an elastic sleeve 322 is fixedly connected to the end of the needle core 15. When the elastic sleeve 322 is pushed towards the needle tip 14, the elastic sleeve 322 will exhibit the following characteristics: Figure 11 In state K, the elastic sleeve 322 is affected by its own elasticity. Both sides of the elastic sleeve 322 contact the inner wall of the connecting tube 16, and the end of the elastic sleeve 322 fixed on the needle core 15 does not contact the connecting tube 16. When the elastic sleeve 322 passes through the slot 222 and pushes the cut protein thread towards the needle tip 14, the gap between the elastic sleeve 322 and the connecting tube 16 is difficult for the protein thread to get stuck. Even if the protein thread gets stuck in the gap because its diameter is too small, the needle core 15 is retracted a certain distance, and the deformation at the contact point between the elastic sleeve 322 and the connecting tube 16 intensifies. At this time, the distance from the contact point between the elastic sleeve 322 and the connecting tube 16 to the fixed end of the elastic sleeve 322 will produce a slight indentation in the direction of the axis of the needle core 15. The gap at the stuck position will increase, so that the protein thread can be withdrawn from the gap, and the needle core 15 can continue to push the protein thread to move. Through the application of the above components, the problem of the protein thread getting stuck in the gap between the needle core 15 and the connecting tube 16 during the pushing process of the needle core 15 is effectively prevented.

[0099] Utilizing the characteristics of the aforementioned device in pulling the needle core 15, after the thread is pushed out, the needle core 15 is pulled away from the needle tip 14. When the elastic sleeve 322 moves to the slot 122 position, the contact point between the elastic sleeve 322 and the connecting tube 16 disengages from the connecting tube 16 at the slot 122. As it continues to move, the elastic sleeve 322 is restricted by the slot 122, causing it to fold over and become as follows. Figure 8In the G state, as the needle core 15 continues to move away from the needle tip 14, when it reaches the connection position between the connecting tube 16 and the guide tube 124, the uncut protein thread will adhere tightly to the guide tube 124 and not enter the connecting tube 16, until the elastic sleeve 322 passes the connection position between the connecting tube 16 and the guide tube 124. When the elastic sleeve 322 passes the slot 2 321 and the threading is completed, it pushes the needle core 15 towards the needle tip 14. At this time, the contact position between the elastic sleeve 322 and the connecting tube 16 reaches the slot 2 321. As the needle core 15 continues to move, the elastic sleeve 322 moves from the... Figure 8 The state of G in the middle becomes as follows Figure 11 In the K state, the uncut protein thread can remain in the guide tube 124 and not enter the connecting tube 16. Through the application of the above components, the problem of the uncut protein thread being bent by the needle core 15 during the pushing and pulling process of the needle core 15, making it difficult to push the protein thread in later, is effectively prevented.
