Description

Technical Field

[0001] The invention relates to the field of medical technology, in particular to a threading and fixing device for preventing tongue from falling back. Background Art

[0002] In modern traffic accidents, sports injuries and accidental injuries, the oral and maxillofacial area is in a relatively exposed anatomical position. Once it is hit, it is very easy to suffer a comminuted fracture of the mandible and chin, resulting in tongue prolapse, which may cause airway obstruction and suffocation. Some patients in deep coma will experience tongue prolapse. When the tongue prolapses, the backward tongue is very likely to cause airway obstruction and cause obstructive suffocation, which can be life-threatening to the patient.

[0003] Currently, there are two main methods to prevent tongue prolapse. One is to use the traditional suturing method to suture and pull the tongue tissue to the outside of the oral cavity. This method often requires professional operation, the steps are cumbersome and time-consuming, and also requires professional medical skills, and the experience of threading, suturing and pulling the tongue many times. The second is a clamp-type tongue puller, which is easy and quick to use. This is to use the clamps in medical equipment, and use a dedicated person to hold and fix the tongue to pull the tongue to keep it pulled outside to avoid blocking the respiratory tract. It is more laborious and not conducive to the transportation and long-term fixation of the injured. Therefore, there is an urgent need to develop a fast and effective device to reduce the occurrence and mortality rate of tongue prolapse.

[0004] Based on this, the present invention designs a threading and fixing device for preventing the tongue from falling back to solve the above problem. Summary of the invention

[0005] The purpose of the present invention is to provide a threading and fixing device for preventing tongue from falling back. The device simply sews the lips and the tongue together quickly, and only needs to pierce the tongue and the lips once, and the thread end on the needle will follow the needle through the tongue and the lips. The threading is fast and the threading process is stable. There is no need to hold the needle and thread for suturing. Moreover, the entire needle does not completely penetrate the tongue and the lips from beginning to end, but only the needle tip can be withdrawn after passing through once. The wound is small and does not need to be clamped all the time. The device does not need to worry about blood stasis and necrosis caused by clamping the tongue for a long time, and effectively prevents tongue from falling back. There is no need for a special person to hold the tongue with forceps at all times, and it can be stably clamped during the transportation of the patient. No professional medical skills are required. It can be completed by holding the device and aligning it and pressing it. The operation is simple and easy to use.

[0006] The present invention is implemented as follows: a threading fixing device for preventing tongue from falling back, comprising:

[0007] The threading rod is a curved rod with a rotating shaft installed at one end and a needle fixed at the other end. The tip of the needle is provided with a threading hole.

[0008] The docking sleeve rod is a hook-shaped structure, one end of which is rotatably connected to the threading rod through a rotating shaft;

[0009] The wire clamp tube is a hollow tubular structure, fixedly connected to the other end of the butt sleeve rod, and provided with a spring clip inside, which can be pressed to open and clamp and seal the inner cavity of the wire clamp tube;

[0010] The needle of the threading rod is rotatably separated and butt-jointed and inserted in the wire clamping tube. When the needle of the threading rod is rotatably inserted in the wire clamping tube, the needle passes through the clamping position of the spring clip.

[0011] Furthermore, the puncture needle and the threading rod are an integral structure, the puncture needle is a smooth stainless steel surgical needle, and the length of the puncture needle is 3 cm-5 cm.

[0012] Furthermore, the wire clamping tube and the docking sleeve rod are an integral structure, a hollow needle-threading sleeve is provided at the connection between the docking sleeve rod and the wire clamping tube, and the inner diameter of the pipe of the wire clamping tube is the same as that of the pipe of the needle-threading sleeve.

[0013] Furthermore, at least two spring clips are arranged in the wire clamping tube. When the two spring clips are not subjected to force, they clamp each other oppositely, and when the spring clips are squeezed, they stick to the inner wall of the wire clamping tube.

[0014] Furthermore, a silicone anti-skid pad is provided on the clamping surface of the two spring clips.

[0015] Furthermore, the rotating shaft is a rotating shaft with a torsion spring inside.

[0016] Furthermore, the threading rod, the docking sleeve rod and the wire clamping tube are all integral structures made of ABS plastic.

[0017] Furthermore, it also includes a protective sleeve, which is a closed hollow telescopic corrugated sleeve, one end of which is fixed on the threading rod, and the puncture needle is arranged in the inner cavity of the protective sleeve without contact, and the protective sleeve is an integral structure made of hemostatic sponge.

[0018] The beneficial effects of the present invention are as follows: 1. The device uses the cooperation of the butt sleeve rod and the needle, so that the needle can quickly pierce the tongue and lips, and once the needle tip of the needle passes through the tongue and lips, the thread head can also be effectively passed through the lips of the tongue, so that the needle can quickly pass the thread head through the tongue and lips, and after the needle drives the thread head through the lips and tongue, the needle will return, and the whole needle does not need to completely pass through the tongue, and the thread head has already sutured the tongue body and the thread head, and the tongue will not be relaxed when there is no external force pressing, so that the tongue can remain extended out of the mouth for a long time, effectively preventing the tongue from falling back and blocking the respiratory tract;

[0019] 2. This device clamps the tongue, and there is no need for a dedicated person to hold the pliers to pull the tongue. Instead, the protruding part of the tongue is fixed relatively to the lips. Then, when the patient is transported, the tongue and the lips are relatively fixed when the patient moves. The tongue and the device will not be displaced relative to each other, and there will be no excessive pulling or insufficient pulling to loosen the tongue.

[0020] 3. This device does not require professional suturing learning or long-term operation training. This device only needs to be aligned with the position of the tongue and lips to perform puncture suturing. The operation is very simple. Just press the threading rod to let the needle pass through the tongue and lips. The wound is small, the recovery is fast in the later stage, and it is not easy to cause wound tearing. There is no need to worry about tissue ischemia and necrosis caused by clamping for too long. Patient transfer and surgical operation are more convenient, and the tongue fixation is more stable.

[0031] See also Figures 1 to 6 As shown, the present invention provides a technical solution: a threading and fixing device for preventing tongue from falling back, comprising:

[0032] The threading rod 1 is a curved rod, with a rotating shaft 21 installed at one end and a needle 11 fixed at the other end, and a threading hole 12 is provided at the tip of the needle 11;

[0033] The docking sleeve rod 2 is a hook-shaped structure, one end of which is rotatably connected to the threading rod 1 through a rotating shaft 21;

[0034] The wire clamp tube 3 is a hollow tubular structure, fixedly connected to the other end of the docking sleeve rod 2, and provided with a spring clip 31 inside, and the spring clip 31 can be pressed to open and clamp the inner cavity of the wire clamp tube 3;

[0035] The puncture needle 11 of the threading rod 1 can be rotatably separated and butt-connected and inserted in the clamping tube 3. When the puncture needle 11 of the threading rod 1 is rotatably inserted in the clamping tube 3, the puncture needle 11 passes through the clamping position of the spring clip 31. The device simply sews the lips and the tongue together quickly, and the puncture needle 11 only needs to pass through the tongue and the lips once, and the thread head on the needle head also follows the needle head through the tongue and the lips. The threading is fast and the threading process is stable. There is no need to use a hand-held vascular clamp to clamp the needle and thread for suturing. Moreover, the entire needle does not completely pass through the tongue and the lips from beginning to end, but only the needle tip can be withdrawn after passing through once. The wound is small and does not need to be clamped all the time. The device does not need to worry about blood stasis and necrosis caused by clamping the tongue for a long time, and can effectively prevent the tongue from falling back. There is no need for a special person to hold the vascular clamp to clamp the tongue at all times. It can also be stably clamped during the transportation of the patient, and does not require long-term training. It only needs to hold the device and press it after alignment. The operation is simple and easy to use.

[0036] The puncture needle 11 and the threading rod 1 are an integral structure, the puncture needle 11 is a smooth stainless steel surgical needle, the length of the puncture needle 11 is 3cm-5cm, so that the puncture needle 11 can withstand strong pressure, and the length can pierce the tongue and lips;

[0037] The clamping tube 3 and the docking sleeve rod 2 are an integral structure. A hollow needle-threading sleeve 22 is provided at the connection between the docking sleeve rod 2 and the clamping tube 3. The inner diameter of the pipe of the clamping tube 3 and the needle-threading sleeve 22 is the same, so that the needle-threading sleeve 22 can accommodate the needle 11 when the needle 11 passes through the clamping tube 3, thereby preventing the needle 11 from being blocked and bent by the docking sleeve rod 2.

[0038] At least two spring clips 31 are arranged in the wire clamp tube 3. When the two spring clips 31 are not subjected to force, they clamp each other in opposite directions. When the spring clips 31 are pressed, they abut against the inner wall of the wire clamp tube 3, so that they can be forced to move away to allow the needle tip of the needle 11 to pass through. When the needle 11 is retracted, the needle 11 can be continuously pressed to clamp the thread end in the threading hole 12.

[0039] The clamping surfaces of the two spring clips 31 are provided with silicone anti-skid pads, which can stably clamp the suture thread and ensure that the thread ends are clamped tightly;

[0040] The rotating shaft 21 is a rotating shaft with a torsion spring inside, so that the device can automatically rebound, and is easy to operate and saves effort when closing the needle;

[0041] The threading rod 1, the docking sleeve rod 2 and the wire clamping tube 3 are all integral structures of ABS plastic, which are light in weight and high in hardness. They can withstand the pressure to pierce the lips and tongue, and can be placed outside the lips without being too heavy.

[0042] The protective sleeve 4 is also included, and the protective sleeve 4 is a closed hollow telescopic corrugated sleeve. One end of the protective sleeve 4 is fixed on the threading rod 1, and the puncture needle 11 is arranged in the inner cavity of the protective sleeve 4 without contact. The protective sleeve 4 is an integral structure made of hemostatic sponge. Such a structural protective sleeve 4 is a corrugated tube made of hemostatic sponge, which can protect the puncture needle 11 and prevent the treated patient from directly seeing such a long puncture needle 11, effectively avoiding the tension of non-medical personnel during operation, and avoiding the patient from having a sense of fear. The entire puncture needle 11 is hidden inside the protective sleeve 4, and the hemostatic sponge can stop bleeding in time when the puncture needle 11 is inserted, without the need for additional hemostatic operation, and can also stop bleeding from the wound caused by the puncture needle very well.

[0043] In a specific embodiment of the present invention:

[0044] The embodiment of the present invention provides a threading and fixing device for preventing the tongue from falling back. The technical problems solved by the present invention are as follows: 1. In the existing technology, there are only two ways to prevent the tongue from falling back. One is to use the traditional suturing method to suture and pull the tongue tissue to the outside of the oral cavity. This method often requires professional operation, the steps are cumbersome and time-consuming, and professional medical skills are required. It also requires experience in threading, suturing and pulling the tongue for many times. Otherwise, not only can the purpose of fixing the tongue not be achieved, but the artery of the tongue may also be punctured to cause a large amount of bleeding. If the tongue slides during suturing and the suturing position with the lips is not appropriate, secondary injury will be caused; 2. The second method is to clamp the tongue with pliers to prevent the tongue from falling back and blocking the respiratory tract. This method requires a person to hold the pliers continuously, which is more laborious and is not conducive to the transportation of the injured, nor is it conducive to long-term fixation. Once the clamping is accidentally relaxed or the hand-held pulling length is not enough, the tongue will fall back again to block the patient's respiratory tract, causing suffocation. This method is unstable for pulling the tongue, and it is also necessary to relax the tongue and lips at intervals to avoid ischemia and necrosis of local tissues of the tongue or lips.

[0045] The technical effects achieved are as follows: 1. The device uses the cooperation of the docking sleeve rod 2 and the puncture needle 11, so that the puncture needle can quickly pierce the tongue and lips, and once the needle tip of the puncture needle 11 passes through the tongue and lips, the thread head can also be effectively passed through the lips of the tongue, so that the puncture needle 11 can quickly pass the thread head through the tongue and lips, and after the puncture needle 11 drives the thread head through the lips and tongue, the puncture needle 11 will rebound with the threading rod 1, and the whole needle does not need to completely pass through the tongue and lips. As long as the needle tip passes through the lips and tongue, the suture thread will follow through the tongue and lips, and the tongue will not be relaxed when there is no external pressure, so that the tongue can remain extended out of the mouth for a long time, effectively preventing the tongue from falling back and blocking the respiratory tract;

[0046] 2. This device sews the tongue and lips together through a thread, so there is no need for a dedicated person to pull the tongue with forceps. Instead, the extended part of the tongue is fixed relatively to the lips. When the patient is transported, the tongue and lips are relatively fixed when the patient moves. The tongue and the device will not be displaced relative to each other, and there will be no excessive pulling or insufficient pulling to loosen the tongue.

[0047] 3. The device does not require professional suturing learning or long-term operation training. The device only needs to be aligned with the tongue and lips to perform puncture suturing. The operation is very simple. Press the threading rod 1 to make the tip of the needle 11 pass through the tongue and lips, and send the thread end into the clamp tube 3.

[0048] 4. This device only requires the needle tip to penetrate the tongue and lips, resulting in a small wound, fast recovery, and less likely to cause wound tearing. With this fixation method, there is no need to worry about tissue ischemia and necrosis caused by clamping for too long. Patient transfer and surgical operations are more convenient, and the tongue is fixed more stably.

[0049] The technical solution in the embodiment of the present invention is to solve the above problems, and the overall idea is as follows:

[0050] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] When the present invention is manufactured, a needle 11 is first manufactured, and a threading hole 12 is opened on the piercing end of the needle 11, and a threading rod 1 is fixed on the thicker end, the threading rod 1 is made of solid ABS hard plastic and is light in weight, and then a rotating shaft 21 is installed on the other end of the threading rod 1 without the needle 11, and a torsion spring is arranged in the rotating shaft 21, and then a docking sleeve rod 2 is installed on the rotating shaft 21, so that the docking sleeve rod 2 and the threading rod 1 can rotate relative to each other, and when no force is applied in normal state, the torsion spring in the rotating shaft 21 has a large elastic force to force the threading rod 1 and the docking sleeve rod 2 to bounce off each other, so that the threading rod 1 and the docking sleeve rod 2 are in an open state at the other end, and at the same time, it is ensured that the threading rod 1 and the docking sleeve rod 2 can only rotate along the rotating shaft 21 and cannot be deflected;

[0052] Then, the wire clamping tube 3 is fixed at one end of the butt sleeve 2 that matches with the needle 11, and the wire clamping tube 3 is hollow inside and connected to the butt sleeve 2. At the same time, the end of the butt sleeve 2 that is butt with the wire clamping tube 3 is hollow, and the inside is a needle sleeve 22 for accommodating the needle 11 passing through the wire clamping tube 3. The butt sleeve 2 and the wire clamping tube 3 are also an integral structure made of ABS plastic. Then, two spring clips 31 are fixed on the inner wall of the wire clamping tube 3, and when no force is applied, the two spring clips 31 are clamped together to block the wire clamping tube 3, and the two spring clips 31 can be forced to spring open to allow the needle 11 to pass through.

[0053] It is also necessary to include a protective cover 4, which is a closed hollow telescopic corrugated sleeve, that is, it is made into the shape of a corrugated tube, and the protective cover 4 is an integral structure made of hemostatic sponge to protect the puncture needle 11. One end of the protective cover 4 is fixed on the threading rod 1, and they need to be completely bonded together, and the entire puncture needle 11 is arranged in the inner cavity of the protective cover 4 without contact, so that the puncture needle 11 is hidden and protected inside the protective cover 4.

[0054] When the present invention is used, the suture is pre-threaded into the threading hole 12 of the needle 11 during production. If the suture falls off during later use, it can be threaded again. Both thread ends can be placed outside the protective cover 4, and the middle section of the suture passes through the threading hole 12. In this way, the needle 11 can move forward to ensure that the suture is taken along with it. Then, the lips and tongue are clamped with a vascular clamp to ensure that the tongue and the lower lip are overlapped as a whole. Then, the clamp tube 3 of the device is placed outside the lips at a suitable position, and the needle 11 is aligned with the position where the threading is required. Then, the threading rod 1 is pressed, and the threading rod 1 pushes the needle 11 to penetrate the soft protective cover 4. At this time, the suture will also be taken out of the protective cover 4, and the needle 11 will not be seen by the patient and the doctor. Even if it is pushed into the tongue, it will not be seen, but will be blocked by the overlapped protective cover 4.

[0055] The threading rod 1 continues to push the needle 11 to penetrate the tongue and continue to be forced to pass through the lower lip. The pressing pressure of the needle 11 pushes the spring clip 31, and the needle 11 continues to move forward and pass through the clamp tube 3. At this time, one end of the suture is released, so that the spring clip 31 clamps the thread end, and then the threading rod 1 is released. The threading rod 1 rebounds under the elastic force of the torsion spring of the rotating shaft 21, so that the needle 11 withdraws from the clamp tube 3 again, and continues to withdraw from the lower lip and the tongue, and the thread end that has passed through is clamped by the spring clip 31, and the clamping surface of the spring clip 31 is provided with a silicone anti-slip pad, which is used to clamp the suture, and the needle 11 is set to be smooth The stainless steel structure can be easily withdrawn from the clamp tube 3, and the other end of the suture is above the tongue and is not inserted into the clamp tube 3. In this way, one end of the suture is above the tongue, and the other end is clamped by the spring clip 31 of the clamp tube 3 under the outer part of the lower lip. In this way, the tongue and the lower lip are fixed and pulled by the suture. If the device blocks the next step of the definitive surgery, the two ends of the suture are tied with surgical knots on the outside of the tongue and the lips, so that the suture becomes a closed loop, the tongue and the lips are completely sealed and fixed together, and the protective cover 4 is torn off the threading rod 1 and pressed on the wound to stop bleeding;

[0056] The device needs to be sterilized during production and stored in a medical sterilization bag for easy storage and removal;

[0057] Without affecting the operation, the device does not need to be disassembled, because the threading rod 1, the docking sleeve rod 2 and the wire clamp tube 3 of the device are all made of ABS plastic, which is light in weight and can be supported by the lips and tongue. The suture thread can fix the tongue and lips, and the protective cover 4 can be stretched out again, and the rebounding puncture needle 11 can be put into the protective cover 4 again to avoid causing fear and tension, and to prevent the puncture needle 11 from directly pricking the lips or the tongue. The device is very convenient to use. Just press to thread the needle, and it can automatically rebound to withdraw the puncture needle 11. The puncture needle 11 does not need to completely pass through the lips and tongue, only the needle tip needs to pass through, resulting in smaller perforations and faster healing after surgery.

[0058] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
