[0002] Due to trauma, various burns and some spontaneous factors, laryngeal cartilage damage and scar hyperplasia lead to laryngeal stenosis and breathing difficulties, which is clinically called laryngeal stenosis. Patients with severe laryngeal stenosis must undergo laryngoplasty in order to rebuild the normal physiological airway. The current conventional surgical methods, whether laser minimally invasive surgery or laryngeal cleft laryngeal mold implantation surgery, are not ideal. The recurrence rate of laser surgery is very high, and laryngeal cleft surgery is traumatic and requires tracheotomy. The obvious scar on the neck also affects the appearance. In addition, the patient's quality of life is poor during the period of laryngeal mold implantation after surgery. The medical expenses required for the operation are high, and the disease is prone to relapse, so the acceptance is poor. Summary of the invention

DETAILED DESCRIPTION

[0020] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.

[0021] like Figure 1-5 As shown, a 3D printing throat mold insertion device described in the present invention includes a thumbtack-type insertion sleeve 1 and an arc-shaped insertion tube core 2. The thumbtack-type insertion sleeve 1 consists of a circular support cap 1-1 and an arc-shaped sleeve component 1-2. The circular support cap 1-1 has a supporting function and can prevent the arc-shaped sleeve component 1-2 from sliding into the throat. The top of the arc-shaped sleeve 1-2 passes through the circular support cap 1-1 and is fixedly connected to the circular support cap 1-1. A tube core 3 is arranged in the arc-shaped sleeve 1-2. The bottom end of the tube core 3 is conical, which is convenient for shielding the bottom end of the arc-shaped sleeve 1-2. The tube core 3 is in sliding contact with the arc-shaped sleeve 1-2, that is, the tube core 3 can be taken out of the arc-shaped sleeve 1-2. Rectangular through grooves 4 are provided on both sides of the bottom end of the arc-shaped insertion tube core 2. A support plate 5 is provided in each of the rectangular through grooves 4. Each of the support plates 5 The plates 5 are rotatably connected to the corresponding rectangular through-grooves 4 through the rotating shaft 6. The two support plates 5 are fixedly connected by a spring 7. When the arc-shaped inserted tube core 2 is inserted, the two support plates 5 are first closed, the spring 7 is compressed, and then the bottom end of the arc-shaped inserted tube core 2 is inserted into the arc-shaped sleeve component 1-2 and pushed downward until the bottom end of the arc-shaped inserted tube core 2 is moved out of the arc-shaped sleeve component 1-2. The two support plates 5 are opened outwardly for support under the elastic force of the spring 7. When the arc-shaped inserted tube core 2 needs to be taken out, it is only necessary to gently pull the arc-shaped inserted tube core 2 upward. When the arc-shaped inserted tube core 2 is lifted and pulled, under the squeezing action of the bottom end of the arc-shaped sleeve component 1-2, the two support plates 5 are gradually closed, and the spring 7 is compressed by times until the bottom end of the arc-shaped inserted tube core 2 is completely entered into the arc-shaped sleeve component 1-2, so that the arc-shaped inserted tube core 2 can be taken out.

[0022] Specifically, two suture holes 8 are provided on the top surface of the circular support cap 1-1, and the two suture holes 8 are distributed on the left and right sides. The suture holes 8 are provided to facilitate the suture and fixation of the circular support cap 1-1 to the patient's throat.

[0023] Specifically, the curvature of the arc-shaped sleeve 1-2 and the arc-shaped insertion tube core 2 is 10 degrees to 30 degrees. Since the curvature of the larynx of different patients is different, the curvature of the arc-shaped sleeve 1-2 and the arc-shaped insertion tube core 2 is 10 degrees to 30 degrees, which can meet the use requirements of different patients and improve the adaptability of the device.

[0024] Specifically, the arc-shaped sleeve 1-2 has a diameter of 4 mm and a wall thickness of 1 mm, and the arc-shaped insertion tube core 2 has a diameter of 3 mm and a wall thickness of 1 mm. The arc-shaped sleeve 1-2 has a diameter of 4 mm and a wall thickness of 1 mm, which can reduce the diameter of the skin incision and improve the appearance. The arc-shaped insertion tube core 2 has a diameter of 3 mm and a wall thickness of 1 mm, which is easy to insert into the arc-shaped sleeve 1-2.

[0025] Specifically, a layer of isolation membrane 9 is provided at the bottom ends of the two support plates 5 facing each other, and the isolation membrane 9 is fixedly connected to the support plates 5. The isolation membrane 9 has an isolation effect on the support plates 5, and can prevent the support plates 5 from directly contacting the throat mucosa.

[0026] Specifically, one end of the rotating shaft 6 is inserted into the corresponding rectangular through slot 4 and can rotate along the insertion hole, and the other end of the rotating shaft 6 is fixedly connected to the corresponding support plate 5. The rotation of the rotating shaft 6 facilitates the support plate 5 to open and support under the elastic force of the spring 7.

[0027] Specifically, the full arc sleeve component 1-2, the arc insertion tube core 2, the support plate 5, the rotating shaft 6, the spring 7 and the isolation membrane 9 are all made of one or more materials selected from polyethylene, polypropylene, polyacrylate, aromatic polyester, silicone rubber, polyurethane, and polyetheretherketone. Polyethylene, polypropylene, polyacrylate, aromatic polyester, silicone rubber, polyurethane, polyetheretherketone, etc. can remain stable for a long time in a physiological environment without degradation, cross-linking, physical wear, etc., and have good mechanical properties.

[0028] Example:

[0029] When using the device, firstly, a transverse skin incision of about 1 cm is made above the patient's Adam's apple to the subcutaneous part, and the skin is slightly freed from the subcutaneous part to the surrounding part, and then a thumbtack-type sleeve 1 is inserted from the center of the front neck incision, and then the tube core 3 is removed, and then the arc-shaped insertion tube core 2 is inserted. When inserting, the two support plates 5 are closed, and at this time, the spring 7 is compressed to facilitate the insertion of the bottom end of the arc-shaped insertion tube core 2 into the arc-shaped sleeve 1-2, until the bottom end of the arc-shaped insertion tube core 2 leaks out from the bottom end of the arc-shaped sleeve 1-2, and the two support plates 5 rotate around the rotating shaft 6 under the elastic force of the spring 7 to open for support, and check whether the throat mold is in place under the support laryngoscope or electronic laryngoscope, and sew it after it is in place. The skin is closed, and after the surgical effect reaches the target after the implantation operation (about 1-3 months), an incision is made along the original incision, and the arc-shaped implant tube core 2 and the implant pushpin-type sleeve 1 are taken out in turn, and the skin incision is sutured; the implantation device of the present invention has a simple structure, can be implanted under general anesthesia supported laryngoscope or local anesthesia electronic laryngoscope, and an incision of about 1 cm is taken in front of the neck to achieve implantation. It is relatively simple to fix after implantation, and it is also relatively convenient to remove it after implantation. It can realize individualized treatment of patients, simplify the operation, reduce trauma, and do not affect the appearance. It improves the quality of life of patients after implantation, reduces clinical treatment costs, and solves the problem of high recurrence rate.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
