Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and more particularly to a wire embedding device. Background Art

[0002] The traditional thread embedding process is as follows:

[0003] S1: Place the thread into the needle body of the thread embedding needle; usually there is a thread pusher at the rear end of the thread embedding needle, which extends into the inside of the needle body. Adjust the position of the thread pusher to facilitate placing the thread into the needle body. Figure 1 As shown in A;

[0004] S2: After inserting the needle into the skin, move it up and down and twist it to perform acupuncture treatment, such as Figure 1 As shown in B;

[0005] S3: Push the needle to push the indwelling suture (catgut) into the skin. Figure 1 As shown in C.

[0006] The above is the traditional thread embedding process. Each time the thread embedding is done, the operator needs to change the thread embedding needle and manually insert the thread from the front end of the needle into the needle body, which is time-consuming and laborious. Experienced Chinese medicine practitioners are mostly older. For older doctors with poor eyesight and trembling hands, it is extremely difficult to insert the indwelling thread into the needle body with tweezers. Because the thread embedding needle needs to pierce the human skin, it is not allowed to be reused as a medical device. Taking advantage of the opportunity that it cannot be reused, we provide a concept, whether the process of installing the indwelling line can be preset, such as sucking the liquid medicine into the syringe in advance to achieve the effect of direct injection. Based on this concept, we found the patent number CN202110782750, named: A bullet-shaped thread embedding device, acupoint thread embedding method and acupoint thread embedding gun. The device can use the thread embedding needle with the indwelling line as a "bullet" to achieve continuous thread embedding operation. The production of the "bullet" can be temporarily made by young people such as the doctor's trainees or nurses, just like sucking the liquid medicine into the syringe in advance, thereby simplifying the doctor's thread embedding process and omitting the time for installing the indwelling line. However, this patent also has some problems. For example, the gun-type device is only suitable for fast thread embedding, and acupuncture techniques such as chasing needles cannot be realized. At the same time, the horizontal external "bullet" will have a great impact on the doctor's operating field of vision. To this end, the present invention is committed to solving one or more of the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0037] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0038] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0039] As shown in the figure, the present invention provides a wire embedding device, comprising:

[0040] A gripping portion 1, used for holding the wire embedding device;

[0041] An injection part 2 is arranged on the holding part 1, and an indwelling wire 5 is arranged in the injection part 2;

[0042] The transmission part 3 is arranged in the holding part 1 and is used to push the indwelling wire 5 in the injection part 2 out of the injection part 2;

[0043] The trigger part 4 is arranged in the holding part 1 and extends to the outside of the holding part 1 . The trigger part 4 is connected to the injection part 2 through the transmission part 3 .

[0044] The injection part 2 (the first embodiment) is composed of a needle body 21 and a connecting piece 22 arranged at one end of the needle body 21. The injection part 2 is connected to the holding part 1 through the connecting piece 22. The transmission part 3 is provided with a thread pushing needle 23, which passes through the connecting piece 22 and extends into the needle body 21. A detachable sealing tube 24 is selectively provided outside the needle body 21. The first embodiment of the injection part 2 adopts the basic structure of the embedded needle in the prior art, such as Figure 2 , 3 shown.

[0045] In the first embodiment of the present invention, we have carried out a series of optimizations based on patent CN202110782750. The injection part 2 (the second embodiment) also includes a magazine 25, and the injection part 2 is provided with at least two, and the outer wall of the connecting member 22 is movably connected to the inner wall of the magazine 25. The holding part 1 is composed of a gun body 11 and a grip 12, the transmission part 3 is arranged in the gun body 11, and the trigger part 4 is arranged at the connection between the gun body 11 and the grip 12. The gun body 11, the grip 12, the transmission part 3, the trigger part 4, and the injection part 2 can all adopt the relevant technical solutions mentioned in CN202110782750. The difference is that the present invention adjusts the injection part 2 from being arranged horizontally side by side to being accommodated in the grip 12, such as Figure 6 As shown, a reset structure such as a spring may be provided at the inner bottom of the handle 12 .

[0046] When using the present invention, the injection part 2 with the preset indwelling line 5 is first installed in the grip 12. When in use, the transmission part 3 is pulled. As the transmission part 3 moves horizontally, sufficient space appears in the gun body 11 to accommodate the injection part 2. Under the action of the bottom spring in the grip 12, the injection part 2 located at the top is pushed into the gun body 11.

[0047] The transmission part 3 is released and reset. During the resetting process, the magazine 25 is pushed to slide along the gun body 11 to the gun head. When the magazine 25 hits the gun head, the magazine 25 stops moving. As the transmission part 3 continues to reset, the connecting piece 22 translates in the magazine 25. At this time, the thread pushing needle 23 and the connecting piece 22 remain relatively still. After the transmission part 3 is reset to the initial position, the connecting piece 22 reaches the specified position in the magazine 25. At this time, the needle body 21 with the sealing tube 24 is pushed out of the magazine 25, and the transmission part 3 abuts against the thread pushing needle 23.

[0048] After removing the sealing tube 24, the needle body 21 can be inserted into the patient's subcutaneous tissue, and the trigger part 4 is pulled. The trigger part 4 adopts the trigger form mentioned in CN202110782750. As the trigger part 4 is pulled, the transmission part 3 pushes the thread pushing needle 23 to push the indwelling thread 5 out of the needle body 21. The indwelling thread 5 is usually a catgut thread.

[0049] After the thread embedding is completed, the needle body 21 is pulled out from the patient's subcutaneous tissue and the sealing tube 24 is put on. The cover plate of the side wall of the gun body 11 is opened, and the injection part 2 after use is taken out. Figure 5 As shown, the removed injection part 2 is treated as medical waste. When the thread embedding is performed again, the above steps are repeated.

[0050] The present invention stores the "bullet" in the grip 12, thereby reducing the impact of the "bullet" on the field of vision, and at the same time greatly optimizing the volume of the device. Compared with the device mentioned in CN202110782750, the volume of the device can be reduced by more than 50%. In addition, because the needle body 21 in the present invention is stored in the magazine 25 before being pushed out by the transmission part 3, when the trainee or nurse installs the indwelling line 5, the needle body 21 can be effectively prevented from being touched and contaminated. Figure 1 In the wire loading method shown in A, the operator can load the wire by leaning against the outer wall of the magazine 25 with his hands, which greatly improves the stability during loading, reduces shaking, and improves the efficiency of loading.

[0051] At the same time, because the needle bodies 21 are all installed in the magazine 25, different needle bodies 21 can be installed in the magazine 25 and distinguished by the external color of the magazine 25. At the same time, the outer surface of the needle body 21 can also be color-marked to distinguish the insertion depth, which is convenient for doctors to flexibly adjust the insertion depth according to different human body structures, so that doctors can more intuitively teach acupuncture and demonstrate operations to students and nurses; multiple semiconductor laser probes can also be reserved at the front end of the gun head of the gun body 11. During the process of acupuncture thread embedding, the acupuncture points can be accurately located by laser, and the local acupuncture points can be irradiated with laser to play the role of invigorating qi, activating blood circulation, relieving pain and reducing inflammation.

[0052] In the previous embodiment, we mentioned that the volume of the device can be reduced by the built-in "bullet" method to increase the doctor's field of vision, but it cannot solve the problem that acupuncture techniques such as needle chasing cannot be operated. Based on the study of the first embodiment, it is not difficult to find that the way to improve the efficiency of thread embedding is to use the injection part 2 with a pre-installed indwelling thread 5 to achieve continuous supply. The magazine 25 is actually still the thread embedding needle mentioned in the prior art, so the setting of the magazine 25 undoubtedly increases the cost of use. For this reason, we provide a second embodiment. Although the thread embedding efficiency is greatly reduced compared with the first embodiment (but still higher than the prior art), this embodiment can achieve acupuncture techniques such as needle chasing, and the operability is more flexible than the first embodiment, and the cost of use is also lower than the first embodiment. In this embodiment, the gripping part 1 is tubular, and the connecting piece 22 of the injection part 2 is detachably connected to one end of the gripping part 1. Usually, the connecting piece 22 is threadedly connected to the end of the gripping part 1, and the other end of the gripping part 1 is provided with a sealing cover 13 for fixing the position of the transmission part 3 and the trigger part 4. The transmission part 3 and the trigger part 4 are both arranged in the grip part 1, and the trigger part 4 extends to the outside of the grip part 1. One end of the trigger part 4 is movably connected to the transmission part 3, and the other end is connected to the sealing cover 13 through the fixing member 14. The injection part 2 adopts the first embodiment, and one end of its thread pusher 23 is located in the needle body 21, and the other end passes through the connecting member 22 and extends into the transmission part 3. The end of the connecting member 22 connected to the grip part 1 is provided with a guide groove 221, and the guide groove 221 is connected to the needle body 21. The guide groove 221 is a diameter-changing groove, usually an arc groove or a tapered groove. When the injection part 2 is replaced, the end of the thread pusher 23 can be guided so that the thread pusher 23 can enter the needle body 21 more quickly and accurately. Therefore, the diameter of the end of the guide groove 221 connected to the grip part 1 is larger than the diameter of the connection between the guide groove 221 and the needle body 21. The transmission part 3 is composed of a limiting part 32, a clamping part 33, a reset part 34, and a linkage part 35 movably connected to the fixed tube 31 through the reset part 34. Figure 7As shown, one end of the thread pushing needle 23 is located in the needle body 21, and the other end passes through the clamping portion 33 and extends into the linkage portion 35. One end of the fixed tube 31 abuts against the end of the connecting piece 22, and the other end abuts against the end of the triggering portion 4, so that the triggering portion 4 can only move along the radial direction of the fixed tube 31. A limiting ring is arranged in the fixed tube 31, so that the cross section of the fixed tube 31 is H-shaped. The limiting ring divides the interior of the fixed tube 31 into a first accommodating space with an opening toward the connecting piece 22 and a second accommodating space with an opening toward the sealing cover 13. The first accommodating space and the second accommodating space are connected through the hollow part of the limiting ring. The limiting portion 32 is located in the first accommodating space, and the reset portion 34 (usually an elastic structure such as a spring can be selected) is located in the second accommodating space. One end of the clamping portion 33 is located in the first accommodating space and is movably connected to the inner wall of the limiting portion 32, and the other end extends into the second accommodating space and abuts against the linkage portion 35. The limiting portion 32 is generally a cylindrical structure with an open end, the open end facing the direction of the connecting piece 22, a through hole is provided at the closed end of the limiting portion 32 opposite to the opening, the clamping portion 33 is composed of at least two clips that can be wrapped around the outer surface of the thread pushing needle 23, when the clamping portion 33 is not subjected to external force, the clip extends in the direction away from the thread pushing needle 23, the portion of the clamping portion 33 located inside the limiting portion 32 is a chuck, the outer diameter of the chuck is adapted to the inner diameter of the limiting portion 32, the outer diameter of the non-chuck portion of the clamping portion 33 is smaller than the inner diameter of the through hole of the limiting portion 32, so the connecting surface between the chuck and the clamping portion 33 is an inclined surface, the axial depth of the first accommodating space is greater than the axial height of the limiting portion 32, and the difference between the two is d, such as Figure 8 The linkage part 35 is a hollow tubular structure, and the end of the linkage part 35 is provided with an abutment end 36, the abutment end 36 extends into the second accommodating space, and the outer diameter of the abutment end 36 located in the second accommodating space is larger than the outer diameter of the connection between the abutment end 36 and the linkage part 35, the end of the reset part 34 abuts against the end of the abutment end 36, the end of the clamping part 33 is connected to the end of the abutment end 36, the end of the linkage part 35 away from the abutment end 36 is a tapered port, and according to different device models, the sealing cover 13 can be provided with an opening connected to the tapered port of the linkage part 35, such as Figure 7 The trigger part 4 is a sheet-like structure, which can be one sheet or multiple sheets. The side wall of the trigger part 4 is provided with a pressing end 41 extending to the outside of the grip part 1. The pressing end 41 can be provided with a (such as Figure 7 ), you can also set multiple (such as Fig.13), one end of the trigger part 4 is provided with an abutting surface abutting against the outer wall of the abutting end 36, and the other end of the trigger part 4 is connected to the fixing member 14 through a limiting column 42, and the limiting column 42 can be used as a rotation point of the trigger part 4. After pressing the pressing end 41, the abutting surface can generate a tendency to move downward with the limiting column 42 as the center of the circle, and push the abutting end 36 to move horizontally during the downward movement, and the outer wall of the fixing member 14 is detachably connected to the inner wall of the holding part 1.

[0053] When this embodiment is in use, the connecting piece 22 and the needle body 21 pre-installed with the indwelling thread 5 are used as the replaceable main body, and the thread pushing needle 23 can be used as a replaceable main body or not be replaced according to the model of the device. In the following embodiments, the example of not replacing the thread pushing needle 23 is used for illustration.

[0054] First, when using it for the first time, insert the thread pusher 23 into the linkage part 35 from the opening of the sealing cover 13 (if the sealing cover 13 is not provided with an opening, it is necessary to open the sealing cover 13 first and then install the thread pusher 23). The tapered port of the linkage part 35 can assist the thread pusher 23 in positioning, so that it can enter the linkage part 35 quickly and accurately until the end of the thread pusher 23 is inserted into the position of the clamping part 33 close to the chuck. The chuck is in a tightened state under the squeezing of the through hole of the limiting part 33, so that the inner diameter at the chuck is smaller than the inner diameter of the clamping part 33 in the second accommodating space, which causes the thread pusher 23 to be pushed to a position close to the chuck, and it can no longer be pushed in because the inner diameter becomes smaller.

[0055] After that, the pressing end 41 is pressed, and the pressing end 41 is bent with the limiting column 42 as the center. Fig.13 As shown, as the pressing end 41 moves downward, the abutting surface will push the abutting end 36 to move horizontally, so that the abutting end 36 squeezes the reset portion 34 and the clamping portion 33. When the clamping portion 33 is pushed to move horizontally, it will first move horizontally with the limiting portion 32 in the first accommodating space until the end of the limiting portion 32 abuts against the connecting member 22. As the clamping portion 33 continues to move, the clamping head of the clamping portion 33 separates from the limiting portion 32 and opens, so that the inner diameter at the clamping head increases. At this time, the thread pushing needle 23 continues to be inserted until it can be observed from the end of the needle body 21 that the thread pushing needle 23 pushes the indwelling thread 5. The pressing end 41 is released, and the abutting end 36 will drive the clamping portion 33 to reset. The clamping portion 33 clamps the thread pushing needle 23. Then, the thread pushing needle 23 extending to the outside of the sealing cover 13 is color-marked to facilitate the subsequent adjustment of the insertion depth. This is the initial state of the second embodiment of the present invention.

[0056] When using, such as Figure 8-12As shown, the doctor can use the gripping part 1 to perform acupuncture techniques such as needle pushing. After completing acupuncture, the doctor presses the pressing end 41, and the abutting end 36 pushes the clamping part 33, which drives the limiting part 32 to move a distance d in the first accommodation space. At this time, the thread pushing needle 23 is also moved a distance d by the clamping part 33, and the indwelling thread 5 is pushed out of the needle body 21. As the clamping part 33 continues to move, the abutting end 36 abuts against the connecting member 22, the clamp separates from the limiting part 32, and the clamping part 33 no longer clamps the thread pushing needle 23. The pressing end 41 is released, and under the action of the resetting portion 34, the abutting end 36 is reset, and the pressing end 41 and the clamping portion 33 are driven to reset. When the clamping portion 33 is reset, its chuck will be contracted by the limiting portion 32. When the chuck completely enters the limiting portion 32, the inner diameter of the chuck is adapted to the diameter of the thread pushing needle 23. With the movement of the abutting end 36, the chuck is reset with the limiting portion 32. When the limiting portion 32 abuts on the limiting ring, the resetting portion 34 The abutment end 36 will still provide axial pulling force for the clamping portion 33, so that the inclined surface of the outer wall of the chuck will be pulled into the through hole of the limiting portion 32, and then the chuck will generate a clamping force to clamp the thread-pushing needle 23. If the doctor believes that the length of the indwelling thread 5 pushed out is not enough, the pressing end 41 can be pressed multiple times to increase the length of the indwelling thread 5 pushed out, and then the needle body 21 can be pulled out. Under the clamping of the human skin and flesh tissue, the indwelling thread 5 will be pulled out of the needle body 21.

[0057] After pulling out the needle body 21, press the pressing end 41, and adjust the position of the end of the thread pushing needle 23 through the thread pushing needle 23 extending outside the sealing cover 13 to restore the thread pushing needle 23 to its initial position. Then, just remove the connecting piece 22 from the holding part 1 and replace it with another injection part 2 with a pre-installed indwelling thread 5. Because the connecting piece 22 is provided with a guide groove 221, the thread pushing needle 23 can be easily inserted into the needle body 21.
