Description

Technical Field

[0001] This invention relates to the field of suture needle technology, and more specifically, to disposable suture needles. Background Technology

[0002] Embedded needles are medical instruments used in acupuncture. They stimulate meridians, balance Yin and Yang, harmonize Qi and blood, and regulate the internal organs through needles and medicated threads, thereby achieving the purpose of treating diseases. The method of using embedded needles is as follows: disinfect the local skin routinely, take a piece of sterilized catgut about one to three centimeters long with forceps, place it at the front end of the needle tube, and then connect the needle core. Tighten or lift the skin at the needle insertion site with the thumb and index finger of the left hand, hold the needle with the right hand, and insert it to the required depth. When the needling sensation is produced, push the needle core while withdrawing the needle tube to embed the catgut into the subcutaneous tissue or muscle layer of the acupoint. Cover the needle hole with sterile gauze.

[0003] Traditional disposable suture needles are not suitable for inexperienced interns. Interns cannot control the depth of acupoints and cannot accurately insert the catgut sutures into the acupoints. Sometimes the needle is inserted too deep and sometimes too shallow. This not only causes discomfort to the patient but also makes it impossible to complete the suture embedding treatment. Therefore, how to design a disposable suture needle that can accurately insert the catgut sutures to the correct depth has become the problem we need to solve. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a disposable suture needle. By incorporating a transmission gear and a threaded post, after medical personnel insert the suture needle into the patient's body, the movable post drives the rack to mesh with the transmission gear, ultimately ensuring that the suture needle reaches a certain position before the catgut enters the patient's body, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a disposable suture needle, comprising a needle body, a hand grip, and catgut. The hand grip is fixedly installed on the top of the needle body. The catgut is disposed inside the needle body. A support block is fixedly installed on one side of the needle body. A movable column is slidably connected inside the support block. A limit baffle is fixedly connected to the top of the movable column. A first support spring is fixedly connected to the bottom of the limit baffle. The first support spring is sleeved on the outer wall of the movable column. A fixing plate is welded to one side of the movable column. A movable rack is welded to the bottom of the fixing plate. The movable rack is slidably connected inside the support block. A transmission gear meshes with one side of the movable rack. A support shaft is connected to the inner wall of the transmission gear via a bearing. One end of the support shaft is fixedly connected to... A support bar is attached, which is fixedly installed on one side of the needle body of the embedding needle. A threaded sleeve is engaged with one side of the transmission gear. A threaded column is threadedly connected to the inner wall of the threaded sleeve. A support member is connected to the outer wall of the threaded sleeve through a bearing. The support member is fixedly installed on the inner wall of the needle body of the embedding needle. A circular support plate is fixedly installed at the bottom of the threaded column. A rotating shaft is hinged to the bottom of the circular support plate. A clamping block is welded to the bottom of the rotating shaft. The clamping block is located on one side of the catgut. A movable plate is fixedly connected to one side of the clamping block. A second support spring is fixedly installed at the bottom of the movable plate. The second support spring is fixedly installed at the bottom of the circular support plate. A fixed plate is fixedly connected to the inner wall of the needle body of the embedding needle. An extrusion strip is fixedly connected to the bottom of the fixed plate. The extrusion strip is located at the bottom of the movable plate.

[0006] By employing the above technical solution, medical personnel insert the thread embedding needle into the patient's acupoints. Once the needle is inside the patient's body, the movable column moves upward, causing the fixed plate to move. The fixed plate then moves the movable rack, which engages with the transmission gear. This transmission gear meshes with the teeth on the outer wall of the threaded sleeve, causing the threaded sleeve to rotate. The threaded sleeve then moves the threaded column downward, which in turn moves the circular support plate downward. The circular support plate then moves the rotating shaft downward, which in turn moves the clamping block downward. The movable plate moves downwards, and after the suture needle enters a certain position within the patient's acupoint, the movable plate comes into contact with the compression strip. The movable plate then pushes the clamping block to move, causing the clamping block to rotate. This prevents the clamping block from holding and fixing the catgut, causing it to fall off the clamping block and into the patient's body. This allows the catgut to be implanted at the designated location within the acupoint for treatment. In this way, even interns who are not good at controlling the depth of acupoint insertion can still perform suture embedding treatment, solving the problem of interns being unable to control the insertion depth of the suture needle, which can cause discomfort to the patient.

[0007] In a preferred embodiment, a suction cup is provided on one side of the needle body of the buried needle, and a piston cylinder is fixedly installed on the top of the suction cup.

[0008] By adopting the above technical solution, the suction cup and piston cylinder can fix the suture needle when the doctor uses it, avoiding the suture needle from shifting due to shaking caused by nervousness and trembling hands of interns after insertion into the acupoint.

[0009] In a preferred embodiment, the number of suction cups is set to two, and the two suction cups are arranged in a mirror symmetrical manner with respect to the vertical center line of the buried needle body.

[0010] By adopting the above technical solution, the two suction cups fix the needle body from both sides, which allows the needle body to be inserted vertically into the patient's body, avoiding tilting when medical staff insert the needle.

[0011] In a preferred embodiment, a corresponding piston is slidably connected to the inner wall of the piston cylinder, and a piston rod is fixedly installed on the top of the corresponding piston.

[0012] By adopting the above technical solution, medical staff can grasp the piston column and pull the corresponding piston to adjust the piston pressure inside the piston cylinder, thereby adjusting the suction force of the suction cup on the patient's skin.

[0013] In a preferred embodiment, a rotating plate is welded to the top of the piston rod, a support rod is hinged to the inner wall of the rotating plate, a fixing member is welded to one end of the support rod, the fixing member is welded to one side of the needle body of the embedded needle, a first fixing ring is fixedly installed on one side of the rotating plate, a movable rod is sleeved on the inner wall of the first fixing ring, a second fixing ring is sleeved on the outer wall of the movable rod, a support column is fixedly connected to the top of the second fixing ring, and the support column is fixedly installed at the bottom of the hand grip.

[0014] By adopting the above technical solution, when medical staff insert the suture needle into the patient's body, the support column will move downward, which will drive the second fixing ring to move downward, the second fixing ring to move the movable rod downward, the movable rod to move the first fixing ring downward, the first fixing ring to drive the rotating plate to rotate, and the rotation of the rotating plate will cause the piston column to move upward.

[0015] In a preferred embodiment, a movable bar is fixedly installed on one side of the piston cylinder, and a movable ring is fixedly connected to one side of the movable bar. The movable ring is slidably connected to the outer wall of the suture needle body.

[0016] By adopting the above technical solution and setting up a movable ring, when the thread embedding needle is inserted into the patient's body, the suction cup and piston cylinder will only adhere to the patient's skin, and as the thread embedding needle penetrates deeper into the patient's body, the piston cylinder and suction cup will not move.

[0017] In a preferred embodiment, a grip groove is provided on one side of the hand grip, and the number of grip grooves is set to two, with anti-slip textures provided on the inner walls of both grip grooves.

[0018] By adopting the above technical solution, the two grip grooves allow patients to easily grip the device with two fingers, while the anti-slip texture increases friction and prevents the grip from slipping off due to hand tremors when medical staff are giving injections.

[0019] The technical effects and advantages of this invention are as follows:

[0020] 1. This invention, by setting up a transmission gear and a threaded column, allows medical staff to insert the suture needle into the patient's body. The movable column drives the rack to mesh with the transmission gear, which in turn causes the threaded sleeve to rotate. The threaded sleeve causes the threaded column to move downward, which in turn causes the clamping block and the catgut to move downward. Once a certain position is reached, the squeezing bar will squeeze the movable plate, which will then push the clamping block to rotate away from the catgut. The movable plate will then cause the clamping block to open, allowing the catgut to fall into the patient's body. This solves the problem of interns being unable to control the insertion depth of the suture needle, which can cause discomfort to the patient.

[0021] 2. This invention, by setting up a piston cylinder and a corresponding piston, allows the suction cup to adhere to the patient's skin when medical staff insert the thread embedding needle into the patient's body. At the same time, as the thread embedding needle is inserted deeper and deeper, the corresponding piston will move upward and upward, thereby increasing the pressure of the piston cylinder on the suction cup. In this way, the suction cup will adhere closer and closer to the skin, avoiding the problem of the thread embedding needle shifting due to shaking caused by nervousness and trembling hands of interns after insertion into the acupoint.

[0030] 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.

[0031] Refer to the instruction manual appendix Figure 1-7 An embodiment of the present invention provides a disposable suture needle, comprising a needle body 1, a handle 2, and catgut 3. The handle 2 is fixedly mounted on the top of the needle body 1, and the catgut 3 is disposed inside the needle body 1. A support block 4 for fixing a movable column 5 is fixedly mounted on one side of the needle body 1. Figure 1 As shown, the support block 4 has a sliding connection inside a movable column 5 for moving the fixed plate 8 upward. A limiting baffle 6 for fixing the first support spring 7 is fixedly connected to the top of the movable column 5. A first support spring 7 for supporting the movable column 5 is fixedly connected to the bottom of the limiting baffle 6. The first support spring 7 is sleeved on the outer wall of the movable column 5. A fixed plate 8 for moving the movable rack 9 is welded to one side of the movable column 5. Figure 2 As shown, a movable rack 9 for engaging the transmission gear 10 is welded to the bottom of the fixed plate 8. The movable rack 9 is slidably connected inside the support block 4. One side of the movable rack 9 engages with the transmission gear 10 for engaging the teeth on the threaded sleeve 13, causing the threaded sleeve 13 to rotate. The inner wall of the transmission gear 10 is connected to a support shaft 11 for fixing the transmission gear 10 via a bearing. Figure 2As shown, a support bar 12 for fixing the support shaft 11 is fixedly connected to one end of the support shaft 11. The support bar 12 is fixedly installed on one side of the needle body 1 of the embedded needle. A threaded sleeve 13 for moving the threaded post 14 downward is meshed on one side of the transmission gear 10. The inner wall of the threaded sleeve 13 is threadedly connected to the threaded post 14 for driving the circular support plate 16 downward. The outer wall of the threaded sleeve 13 is connected to a support member 15 for fixing the threaded sleeve 13 through a bearing. The support member 15 is fixedly installed on the inner wall of the needle body 1 of the embedded needle. Figure 4 As shown, a circular support plate 16 for driving the rotating shaft 17 to move downward is fixedly installed at the bottom of the threaded column 14. The rotating shaft 17 for driving the clamping block 18 to move downward is hinged to the bottom of the circular support plate 16. A clamping block 18 for clamping and fixing the catgut 3 is welded to the bottom of the rotating shaft 17. The clamping block 18 is located on one side of the catgut 3. A movable plate 19 for driving the clamping block 18 to rotate is fixedly connected to one side of the clamping block 18. A second support spring 20 for supporting the movable plate 19 is fixedly installed at the bottom of the movable plate 19. The second support spring 20 is fixedly installed at the bottom of the circular support plate 16. A fixed plate 21 for supporting the extrusion strip 22 is fixedly connected to the inner wall of the needle body 1. An extrusion strip 22 for extruding the movable plate 19 is fixedly connected to the bottom of the fixed plate 21. The extrusion strip 22 is located at the bottom of the movable plate 19.

[0032] It should be noted that after the medical staff inserts the thread embedding needle into the patient's acupoint, the movable column 5 moves upward, which in turn moves the fixed plate 8. The fixed plate 8 then moves the movable rack 9, which engages with the transmission gear 10. The transmission gear 10 then engages with the teeth on the outer wall of the threaded sleeve 13, causing the threaded sleeve 13 to rotate. This causes the threaded column 14 to move downward, which in turn moves the circular support plate 16 downward. The circular support plate 16 then moves the rotating shaft 17 downward, which in turn moves the clamping block 18 downward. The clamping block 18 then moves the movable plate 19 downward. After the needle is inserted into a specific location within the acupoint, the movable plate 19 comes into contact with the compression strip 22. The compression strip 22 then compresses one end of the movable plate 19, causing it to rotate. This rotation pushes the clamping block 18 away from the catgut 3, preventing it from holding and fixing the catgut 3. The catgut 3 then falls off the clamping block 18 and into the patient's body. This allows the catgut 3 to be implanted at the designated location within the acupoint for treatment. This method allows even interns who are not skilled in controlling the depth of acupoint insertion to perform the implantation treatment, solving the problem of interns being unable to control the insertion depth of the needle, which can cause discomfort to the patient.

[0033] At the same time, such as Figure 6 As shown, one side of the suture needle body 1 is provided with a suction cup 23 for adhering to the patient's skin. A piston cylinder 24 for adjusting the suction force of the suction cup 23 is fixedly installed on the top of the suction cup 23. Two suction cups 23 are provided, arranged in a mirror-symmetrical manner about the vertical center line of the suture needle body 1. The two suction cups 23 fix the suture needle body 1 from both sides, allowing the suture needle body 1 to be inserted vertically into the patient's body, preventing tilting during needle insertion. A corresponding piston 25 for adjusting the suction force of the piston cylinder 24 is slidably connected to the inner wall of the piston cylinder 24. Figure 7 As shown, a piston rod 26 is fixedly installed on the top of the corresponding piston 25 to drive the piston 25 to move. A rotating plate 27 for driving the piston rod 26 to move is welded to the top of the piston rod 26. A support rod 28 for supporting the rotating plate 27 is hinged to the inner wall of the rotating plate 27. A fixing member 29 for fixing the support rod 28 is welded to one end of the support rod 28. The fixing member 29 is welded to one side of the needle body 1 of the embedded needle. A first fixing ring 30 for driving the rotating plate 27 to rotate is fixedly installed on one side of the rotating plate 27. A movable rod 31 for driving the first fixing ring 30 to move is sleeved on the inner wall of the first fixing ring 30. Figure 6 As shown, a second fixed ring 32 for moving the movable rod 31 is sleeved on the outer wall of the movable rod 31. A support column 33 for moving the second fixed ring 32 is fixedly connected to the top of the second fixed ring 32. The support column 33 is fixedly installed at the bottom of the hand grip 2. A movable strip 34 for fixing the movable ring 35 is fixedly installed on one side of the piston cylinder 24. A movable ring 35 for fixing the piston cylinder 24 is fixedly connected to one side of the movable strip 34. The movable ring 35 is slidably connected to the outer wall of the needle body 1 of the buried needle.

[0034] It should be noted that when medical staff insert the needle, the suction cup 23 will adhere to the patient's skin. When the medical staff pushes the needle into the patient's body, the support column 33 will move downward, which will cause the second fixing ring 32 to move downward. The second fixing ring 32 will cause the movable rod 31 to move downward, which will cause the first fixing ring 30 to move downward. The first fixing ring 30 will then cause the rotating plate 27 to rotate. The rotation of the rotating plate 27 will cause the piston column 26 to move upward, which will cause the corresponding piston 25 to move upward, thereby adjusting the air pressure in the piston cylinder 24. In this way, the deeper the needle is inserted into the patient's body, the tighter the suction cup 23 adheres, avoiding the possibility of the needle shifting due to the intern's nervous hand shaking after insertion into the acupoint.

[0035] At the same time, such as Figure 3As shown, a grip groove 36 is provided on one side of the hand grip 2 to facilitate the staff to grasp the hand grip 2. There are two grip grooves 36. The two grip grooves 36 can make it convenient for the patient to use two fingers to grip the device. The inner wall of the two grip grooves 36 is provided with anti-slip texture 37 to improve friction.

[0036] It should be noted that the two grip grooves 36 make it convenient for patients to hold the device with two fingers, while the anti-slip texture 37 prevents the hand grip 2 from falling off due to hand tremors when medical staff insert needles.

[0037] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
