Description

Technical Field

[0001] This invention belongs to the field of dental restoration, specifically a dental fixation device. Background Technology

[0002] With the continuous advancement of medical technology, more and more diseases are being overcome. When faced with severe laryngeal obstruction caused by laryngeal inflammation, tumors, trauma, foreign bodies, etc., the common treatment is to perform a tracheotomy on the patient. However, some elderly patients may experience tooth loss during or after the surgery.

[0003] Existing technologies also offer some solutions, such as using braces to fix and protect patients' teeth. Existing braces can be divided into ordinary metal braces, lingual braces, silicone braces, ceramic braces, and self-ligating braces. By covering the outer surface of the teeth, they can fix the position of the teeth and reduce the impact on the teeth from external forces.

[0004] Existing technology uses some large silicone braces, which can cause discomfort in the patient's mouth. Due to their large size, they are also not conducive to doctors performing surgery on patients. Other types of braces, such as metal braces, are more troublesome to wear and inconvenient to install.

[0005] Therefore, the present invention provides a tooth fixation device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A tooth fixation device according to this invention includes multiple support plates, fixation lines, a comb, a fastening device, a connecting line, and an elastic band. The support plates are made of elastic material. Fixation lines are fixedly connected to both ends of the support plates. A comb is fixedly connected to the end of the fixation line away from the support plate. A fastening device is installed between the fixation lines and the comb. A connecting line is fixedly connected between the support plates and the comb. An elastic band is fixedly connected between the connecting lines. During operation, the fixation lines are looped onto the outer surface of the teeth, and then tightened by the fastening device, thereby clamping the teeth between the support plates and the comb. Then, the elastic band is looped around the patient's chin, causing the connecting line connected to the elastic band to press downwards against the top of the teeth, thus fixing the teeth. Simultaneously, during surgery, if a tooth accidentally falls out, the fixation lines and connecting lines can also hold the tooth in place, preventing it from falling deep into the patient's throat and causing breathing obstruction.

[0008] Preferably, the fastening device includes a fixed post, a threaded hole, a rotating groove, a rotating rod, and a cross groove; the fixed post has a threaded hole at the end away from the support plate; a rotating groove is formed at the bottom of the threaded hole; a rotating rod is threaded into the threaded hole; the fixing wire passes through the fixed post and is fixedly connected to the surface of the rotating rod in the rotating groove; a cross groove is formed at the end of the rotating rod away from the threaded hole; medical personnel can tighten the cross groove with a screwdriver; during operation, the rotation of the rotating rod causes the fixing wire to wrap around the surface of the rotating rod, thereby shortening the fixing wire and making it more securely fastened to the outer surface of the patient's tooth, thus facilitating installation by medical personnel and reducing the installation difficulty.

[0009] Preferably, the end of the fixing post away from the rotating rod is fixedly connected to a plurality of evenly arranged conical protrusions; the conical protrusions are made of rigid material; a slide rod is slidably connected to the middle of the end of the fixing post near the conical protrusions; a tray is fixedly connected to the end of the slide rod away from the connecting plate; an annular liquid bladder is fixedly connected to the outside of the tray and the slide rod, and dentin adhesive is disposed in the annular liquid bladder; during operation, the medical staff rotates the rotating rod, which causes the fixing line to contract, thereby causing the surface of the patient's teeth to squeeze the tray, and then the tray causes the annular liquid bladder to move closer to the fixing post. At this time, the conical protrusion on the fixed end face of the fixing post will puncture the annular liquid bladder, causing the dentin adhesive in the annular liquid bladder to leak out and remain on the surface of the patient's teeth. Then, the medical staff uses an ultraviolet lamp to irradiate the dentin adhesive to light-cure the dentin adhesive, thereby further fixing the patient's teeth.

[0010] Preferably, the tray surface has multiple evenly spaced through holes; a sponge pad is fixedly connected to the side of the tray away from the annular liquid bladder; the sponge pad is relatively dry; during operation, after the annular liquid bladder is punctured, the dentin adhesive inside the annular liquid bladder flows out through the through holes on the tray surface, and then wets the sponge pad, increasing the contact area between the dentin adhesive and the patient's teeth, thereby further improving the bonding effect with the teeth.

[0011] Preferably, the fixing line is fixedly connected to an insert plate on the surface between the support plate and the comb; the bottom of the insert plate has a wedge-shaped structure; the wedge-shaped structure makes it easy for medical staff to insert the insert plate into the gap between the patient's teeth; during operation, by inserting the insert plate into the gap between the patient's teeth, it is convenient for medical staff to put the fixing line on the outer surface of the patient's teeth, reducing the difficulty for medical staff to install the embodiment of the present invention.

[0012] Preferably, the surface of the insert plate has multiple evenly arranged grooves; rollers are rotatably connected in the grooves; during operation, the rollers in the grooves contact the surface of the patient's teeth and rotate during insertion, thereby reducing the friction when the insert plate is inserted.

[0013] Preferably, a silicone pad is fixed to the side surface of the roller; a plurality of evenly arranged silicone protrusions are fixed to the surface of the silicone pad; a silicone strip is fixed between the silicone protrusions; the silicone protrusions and silicone strips can rub against the patient's teeth; during operation, the silicone protrusions and silicone strips on the surface of the roller can rub against the surface of the patient's teeth, thereby cleaning the gaps between the patient's teeth and reducing the discomfort when foreign objects are stuck in the gaps between the patient's teeth.

[0014] Preferably, a limiting groove is formed on the side surface of the support plate away from the fixed post; an elastic plate is provided on the support plate at the corresponding position of the limiting groove; a limiting plate adapted to the limiting groove is fixedly connected to the side surface of the elastic plate near the limiting groove; the limiting plate is made of elastic material; during operation, the limiting plate is inserted into the limiting groove, and then the elastic plate abuts against the support plate through its elasticity, so that the support plate fits against the surface of the patient's teeth, thereby improving the support effect of the support plate on the patient's teeth.

[0015] Preferably, a first magnet is fixedly connected to the surface of the limiting plate; a second magnet is fixedly connected to the inner wall of the limiting groove at the corresponding position of the first magnet; the first magnet and the second magnet attract each other; during operation, the second magnet on the surface of the limiting plate will attract the first magnet in the limiting groove, thereby improving the stability when the limiting plate and the limiting groove are engaged. At the same time, when the first magnet and the second magnet attract each other, they can play a guiding role, making it convenient for medical staff to install the limiting plate.

[0016] Preferably, a plurality of uniformly arranged strip-shaped airbags are fixedly connected to the surface of the elastic band near the fixing line; the strip-shaped airbags are interconnected; one end of one of the strip-shaped airbags is equipped with an air guide tube; medical staff can inflate the strip-shaped airbag with air through the air guide tube; during operation, gas is inflated into the strip-shaped airbag through the air guide tube, so that the airbag fills the space between the patient's chin and the elastic band, thereby preventing the patient's chin from being tightly pressed against the elastic band, and thus reducing the patient's discomfort when feeling stuffy.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The tooth fixation device of the present invention uses a fastening device to tighten the fixing line, thereby clamping the tooth with the support plate and the comb. Then, an elastic band is put around the patient's chin, so that the connecting line connected to the elastic band presses down on the top of the tooth, thereby fixing the tooth. At the same time, if the tooth is accidentally dislodged during the operation, the fixing line and the connecting line can also tie the tooth to prevent the tooth from falling deep into the patient's throat and causing breathing obstruction.

[0019] 2. The tooth fixation device of the present invention, by rotating the rotating rod, causes the fixing wire to wrap around the surface of the rotating rod, thereby shortening the fixing wire and making the fixing wire more firmly attached to the outer surface of the patient's tooth, thus facilitating the installation by medical staff and reducing the installation difficulty for medical staff.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1

[0030] like Figure 1As shown in the embodiment of the present invention, a dental fixation device includes multiple support plates 1, fixing wires 2, combs 3, fastening devices 4, connecting wires 5, and elastic bands 6. The support plates 1 are made of elastic material. Fixing wires 2 are fixedly connected to both ends of the support plates 1. A comb 3 is fixedly connected to the end of each fixing wire 2 away from the support plate 1. Fastening devices 4 are installed between the fixing wires 2 and the combs 3. Connecting wires 5 are fixedly connected between the support plates 1 and the combs 3. Elastic bands 6 are fixedly connected between the connecting wires 5. During operation, this device can cause problems during or after surgery on the patient's throat or mouth. To protect the patient's teeth from loosening or even falling out, this invention can be used. A fixing thread 2 is placed over the outer surface of the tooth, and then tightened using a fastening device 4. This causes the support plate 1 and the comb 3 to clamp the tooth. An elastic band 6 is then placed over the patient's chin, causing the connecting line 5, connected to the elastic band 6, to press downwards against the top of the tooth, thus fixing it in place. Furthermore, if a tooth accidentally falls out during surgery, the fixing thread 2 and the connecting line 5 can also hold the tooth in place, preventing it from falling deep into the patient's throat and obstructing breathing.

[0031] like Figures 1 to 2 As shown, the fastening device 4 includes a fixing post 7, a threaded hole 8, a rotating groove 9, a rotating rod 10, and a cross groove 11. The fixing post 7 has a threaded hole 8 at its end away from the support plate 1. A rotating groove 9 is formed at the bottom of the threaded hole 8. A rotating rod 10 is threaded into the threaded hole 8. The fixing wire 2 passes through the fixing post 7 and is fixedly connected to the surface of the rotating rod 10 within the rotating groove 9. A cross groove 11 is formed at the end of the rotating rod 10 away from the threaded hole 8. Medical personnel can use a screwdriver to tighten the cross groove 11. During operation, when the doctor places the fixing wire 2 on the outer surface of the patient's tooth, they first rotate the rotating rod 10. The rotation of the rotating rod 10 causes the fixing wire 2 to wrap around the surface of the rotating rod 10, thus shortening the fixing wire 2 and allowing it to be more securely fastened to the outer surface of the patient's tooth. This facilitates installation by medical personnel and reduces the difficulty of installation.

[0032] like Figure 2As shown, the fixed post 7 has multiple evenly arranged conical protrusions 12 fixedly connected to one end away from the rotating rod 10; the conical protrusions 12 are made of rigid material; a sliding rod 13 is slidably connected to the middle of the fixed post 7 near the conical protrusions 12; a tray 14 is fixedly connected to the end of the sliding rod 13 away from the connecting plate; an annular liquid bladder 15 is fixedly connected to the outside of the tray 14 and the sliding rod 13, and dentin adhesive is placed inside the annular liquid bladder 15; during operation, when the medical staff rotates the rotating rod 10, it will cause the fixed line 2 to contract, thereby causing the surface of the patient's teeth to press against the tray 14, and then the tray 14 will drive the annular liquid bladder 15 to move closer to the fixed post 7. At this time, the conical protrusions 12 on the fixed end face of the fixed post 7 will puncture the annular liquid bladder 15, causing the dentin adhesive inside the annular liquid bladder 15 to leak out and remain on the surface of the patient's teeth. Then, the medical staff will use an ultraviolet lamp to irradiate the dentin adhesive to light-cure the dentin adhesive, thereby further fixing the patient's teeth.

[0033] like Figure 2 As shown, the surface of the tray 14 has a plurality of evenly arranged through holes 16; a sponge pad 17 is fixedly connected to the side of the tray 14 away from the annular liquid bladder 15; the sponge pad 17 is relatively dry; during operation, when the annular liquid bladder 15 is punctured, the dentin adhesive inside the annular liquid bladder 15 flows out through the through holes 16 on the surface of the tray 14, and then wets the sponge pad 17, increasing the contact area between the dentin adhesive and the patient's teeth, thereby further improving the bonding effect with the teeth.

[0034] like Figure 1 and Figure 3 As shown, the fixing line 2 is fixedly connected to the surface between the support plate 1 and the comb 3 by an insert plate 18; the bottom of the insert plate 18 has a wedge-shaped structure; the wedge-shaped structure makes it convenient for medical staff to insert the insert plate 18 into the gap between the patient's teeth; during operation, when medical staff put the fixing line 2 on the outer surface of the teeth, they can insert the insert plate 18 into the gap between the patient's teeth, thereby making it convenient for medical staff to put the fixing line 2 on the outer surface of the patient's teeth and reducing the difficulty for medical staff to install the embodiment of the present invention.

[0035] like Figure 1 and Figure 3 As shown, the surface of the insert plate 18 is provided with a plurality of evenly arranged grooves 19; a roller 20 is rotatably connected in the groove 19; during operation, when the medical staff inserts the insert plate 18 into the gap between the patient's teeth, the roller 20 in the groove 19 contacts the surface of the patient's teeth and rotates during the insertion process, thereby reducing the friction force when the insert plate 18 is inserted.

[0036] like Figure 4As shown, a silicone pad 21 is fixedly connected to the side surface of the roller 20; a plurality of evenly arranged silicone protrusions 22 are fixedly connected to the surface of the silicone pad 21; a silicone strip 23 is fixedly connected between the silicone protrusions 22; the silicone protrusions 22 and the silicone strip 23 can rub against the patient's teeth; during operation, when the roller 20 rotates, the silicone protrusions 22 and the silicone strip 23 on the surface of the roller 20 can rub against the surface of the patient's teeth, thereby cleaning the gaps between the patient's teeth and reducing the discomfort when foreign objects are stuck in the gaps between the patient's teeth.

[0037] like Figure 1 and Figure 5 As shown, a limiting groove 24 is formed on the side surface of the support plate 1 away from the fixing post 7; an elastic plate 25 is provided at the corresponding position of the limiting groove 24 on the support plate 1; a limiting plate 26 adapted to the limiting groove 24 is fixedly connected to the side surface of the elastic plate 25 near the limiting groove 24; the limiting plate 26 is made of elastic material; during operation, in order to ensure that the support plate 1 can fit against the surface of the patient's teeth and adapt to the curvature of the patient's teeth, the limiting plate 26 can be inserted into the limiting groove 24, and then the elasticity of the elastic plate 25 can be used to hold the support plate 1 in place, so that the support plate 1 fits against the surface of the patient's teeth, thereby improving the support effect of the support plate 1 on the patient's teeth.

[0038] like Figure 1 and Figure 5 As shown, a first magnet 27 is fixedly connected to the surface of the limiting plate 26; a second magnet 28 is fixedly connected to the inner wall of the limiting groove 24 at the corresponding position of the first magnet 27; the first magnet 27 and the second magnet 28 attract each other; during operation, when medical personnel insert the limiting plate 26 into the limiting groove 24, the second magnet 28 on the surface of the limiting plate 26 will attract the first magnet 27 in the limiting groove 24, thereby improving the stability of the limiting plate 26 when it is engaged with the limiting groove 24. At the same time, the attraction between the first magnet 27 and the second magnet 28 can play a guiding role, making it convenient for medical personnel to install the limiting plate 26.

[0039] Example 2

[0040] like Figure 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a plurality of uniformly arranged strip-shaped airbags 29 are fixedly connected to the surface of the elastic band 6 near the fixing line 2; the strip-shaped airbags 29 are interconnected; one end of one of the strip-shaped airbags 29 is equipped with an air guide tube 30; medical staff can inflate air into the strip-shaped airbag 29 through the air guide tube 30; when working, if the patient wears the elastic band 6 for a long time, it will make the patient's chin feel stuffy and hot. Air can be inflated into the strip-shaped airbag 29 through the air guide tube 30, so that the airbag fills between the patient's chin and the elastic band 6, thereby avoiding the patient's chin from being tightly fitted to the elastic band 6, and thus reducing the patient's discomfort when feeling stuffy and hot.

[0041] During or after surgery on a patient's throat or mouth, teeth may become loose or even fall out. To protect the patient's teeth, this invention can be used. A fixing thread 2 is placed on the outer surface of the tooth, and then the fixing thread 2 is tightened by a fastening device 4. This allows the support plate 1 and the comb 3 to clamp the tooth. Then, an elastic band 6 is placed on the patient's chin, causing the connecting line 5 connected to the elastic band 6 to press down on the top of the tooth, thereby fixing the tooth. At the same time, if a tooth is accidentally dislodged during surgery, the fixing thread 2 and the connecting line 5 can also hold the tooth in place, preventing it from falling deep into the patient's throat and causing breathing obstruction.

[0042] When the doctor places the fixation suture 2 on the outer surface of the patient's tooth, he first rotates the rotating rod 10. The rotation of the rotating rod 10 causes the fixation suture 2 to wrap around the surface of the rotating rod 10, thereby shortening the fixation suture 2. This allows the fixation suture 2 to be more firmly attached to the outer surface of the patient's tooth, which facilitates the installation by medical staff and reduces the difficulty of installation.

[0043] When the medical staff rotates the lever 10, it causes the fixing line 2 to contract, which in turn causes the surface of the patient's teeth to press against the tray 14. The tray 14 then moves the annular liquid bladder 15 closer to the fixing post 7. At this time, the conical protrusion 12 on the fixed end face of the fixing post 7 will puncture the annular liquid bladder 15, causing the dentin adhesive inside the annular liquid bladder 15 to leak out and remain on the surface of the patient's teeth. Then, the medical staff uses an ultraviolet lamp to irradiate the dentin adhesive, which light-cures the dentin adhesive, thereby further fixing the patient's teeth.

[0044] When the annular liquid bladder 15 is punctured, the dentin adhesive inside the annular liquid bladder 15 flows out through the through hole 16 on the surface of the tray 14, and then soaks the sponge pad 17, increasing the contact area between the dentin adhesive and the patient's teeth, thereby further improving the bonding effect with the teeth.

[0045] When medical staff place the fixing wire 2 on the outer surface of the tooth, the insert plate 18 can be inserted into the gap between the patient's teeth, which makes it easier for medical staff to place the fixing wire 2 on the outer surface of the patient's teeth and reduces the difficulty for medical staff to install the embodiment of the present invention.

[0046] When medical staff insert the insert 18 into the gap between the patient's teeth, the roller 20 in the groove 19 contacts the surface of the patient's teeth and rotates during the insertion process, thereby reducing the friction when the insert 18 is inserted.

[0047] When the roller 20 rotates, the silicone protrusions 22 and silicone strips 23 on the surface of the roller 20 can rub against the surface of the patient's teeth, thereby cleaning the gaps between the patient's teeth and reducing the discomfort when foreign objects are stuck in the gaps between the patient's teeth.

[0048] In order to ensure that the support plate 1 can fit the surface of the patient's teeth and adapt to the curvature of the patient's teeth, the limiting plate 26 can be inserted into the limiting groove 24, and then the elastic plate 25 can be used to hold the support plate 1 in place, so that the support plate 1 fits the surface of the patient's teeth and improves the support effect of the support plate 1 on the patient's teeth.

[0049] When medical staff insert the limiting plate 26 into the limiting groove 24, the second magnet 28 on the surface of the limiting plate 26 will attract the first magnet 27 in the limiting groove 24, thereby improving the stability of the limiting plate 26 when it is engaged with the limiting groove 24. At the same time, the attraction between the first magnet 27 and the second magnet 28 can play a guiding role, making it easier for medical staff to install the limiting plate 26.

[0050] Wearing the elastic band 6 for a long time can make the patient's chin feel stuffy and hot. In this case, air can be injected into the strip-shaped airbag 29 through the air tube 30, so that the airbag fills the space between the patient's chin and the elastic band 6, thereby preventing the patient's chin from being tightly pressed against the elastic band 6 and reducing the patient's discomfort when feeling stuffy and hot.
