Description

Technical Field

[0001] This utility model relates to medical device technology, specifically to an oral stent for radiotherapy positioning in radiotherapy departments. Background Technology

[0002] Radiotherapy, as a crucial treatment for head and neck tumors, has significantly improved postoperative survival rates. However, over 80% of patients undergoing radiotherapy for head and neck tumors experience substantial oral complications. Preoperatively, surgeons can precisely mark the area of ​​tumor tissue requiring radiotherapy (the target zone) and concentrate the radiation dose within this area, while minimizing the radiation dose to healthy tissues further away from the target zone. Therefore, radiotherapy for head and neck tumors requires the design and fabrication of an oral radiotherapy framework to push healthy oral tissues as far away from the radiotherapy target zone as possible, thereby achieving accurate positioning, reducing placement errors and tissue damage, and protecting oral function.

[0003] While existing radiotherapy positioning dental stents made of dental materials such as silicone rubber can ensure positioning accuracy, comfort, and individualization, their complex manufacturing process (requiring dental professionals and technicians), long manufacturing time, and high cost make them unsuitable for widespread clinical use. Utility Model Content

[0004] The purpose of this invention is to provide an oral support for radiotherapy positioning in radiotherapy departments, in order to solve the problem that the existing individualized oral support for radiotherapy made of dental materials such as silicone rubber can ensure positioning accuracy, comfort and achieve individualization, but is not convenient for clinical promotion and use due to its complicated manufacturing method (requiring dental professionals and technicians to make it), long manufacturing time and high cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oral support for radiotherapy positioning in radiotherapy departments, comprising:

[0006] Dental stents;

[0007] The upper bow groove has a lower bow groove at one end. The upper bow groove and the lower bow groove are connected by two rotating shafts. A return spring is symmetrically installed at the bottom of the lower bow groove. A pressure plate is installed at the bottom of the symmetrically arranged return spring.

[0008] Two symmetrically arranged fixing components are installed between the upper and lower arch grooves;

[0009] A clamping assembly is installed inside the lower bow groove.

[0010] Furthermore, each of the two symmetrically arranged fixing components includes:

[0011] Fixed frame one, which is fixedly installed at the bottom of the upper arch groove;

[0012] Fixed frame two is fixedly installed on the top of the lower arch groove;

[0013] The support frame has one end rotatably connected to the inner wall of the first fixed frame and the other end rotatably connected to the inner wall of the second fixed frame.

[0014] The cooling frame is fixedly installed on the inside of the support frame.

[0015] Furthermore, the gripping assembly includes:

[0016] The airbag is fixedly installed inside the lower arch groove;

[0017] The air tube is connected to the airbag and is fixedly connected to the inner wall of the lower arch groove.

[0018] An air inflator, which is connected to one end of the air inlet tube.

[0019] Compared with existing technologies, the oral support for radiotherapy positioning provided by this utility model is more convenient, allowing patients to wear it themselves without having to visit a dentist. It improves the fixation accuracy and repeatability of the upper and lower jaws and tongue, reducing adverse reactions such as oral mucositis, taste disorders, and dry mouth. The oral support achieves individualization while improving fixation accuracy, facilitating patient occlusion, and its simple manufacturing method makes it easy for clinical application and widespread adoption.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] Please see Figures 1-5 An oral support for radiotherapy positioning in a radiotherapy department, comprising:

[0031] Dental stent 1;

[0032] The upper bow groove 11 has a lower bow groove 12 at one end. The upper bow groove 11 and the lower bow groove 12 are connected by two rotating shafts 13. A return spring 15 is symmetrically installed at the bottom of the lower bow groove 12. A tongue depressor 14 is installed at the bottom of the symmetrically arranged return spring 15.

[0033] Two symmetrically arranged fixing components 2 are installed between the upper arch groove 11 and the lower arch groove 12;

[0034] The clamping component 3 is installed inside the lower bow groove 12.

[0035] In a specific implementation, both the upper arch groove 11 and the lower arch groove 12 are made of resin materials such as methyl methacrylate resin or polylactic acid, which have the advantages of being non-toxic and having no adverse effects on the radiotherapy dose. Furthermore, individualized manufacturing can better adapt to the patient's oral cavity shape and reduce the irradiation dose to normal tissues.

[0036] Both symmetrically arranged fixing components 2 include:

[0037] Fixed frame 23 is fixedly installed at the bottom of upper arch groove 11;

[0038] Fixed frame 24 is fixedly installed on the top of the lower arch groove 12;

[0039] The support frame 21 has one end rotatably connected to the inner wall of the first fixed frame 23, and the other end rotatably connected to the inner wall of the second fixed frame 24.

[0040] The cooling frame 22 is fixedly installed on the inside of the support frame 21.

[0041] The specific implementation method is that the cooling frame 22 contains ice blocks for cooling, which is used to reduce oral mucosal damage, relieve oral pain, improve radiotherapy tolerance, reduce radiotherapy interruption, and promote oral mucosal repair.

[0042] The clamping component 3 includes:

[0043] Airbag 33 is fixedly installed inside the lower arch groove 12;

[0044] The air duct 32 is connected to the airbag 33 and is fixedly connected to the inner wall of the lower arch groove 12.

[0045] The air inflator 31 is connected to one end of the air guide tube 32.

[0046] In a specific implementation, the airbag 33 is used to fix the lower arch groove 12 to the patient's gums to prevent the device from falling off during use and affecting the radiotherapy work.

[0047] Working principle: In use, the lower arch groove 12 is first placed on the outside of the patient's lower gingiva. Due to the presence of the return spring 15, the tongue depressor 14 presses down on the patient's tongue. The air inflator 31 is used to inflate the air bag 33 through the air tube 32, so that the air bag 33 is inflated and clamps the patient's gingiva. By adjusting the support frame 21, the angle of the upper arch groove 11 and the lower arch groove 12 is further adjusted. Then, the upper arch groove 11 is fixed to the patient's upper gingiva for subsequent radiotherapy.

[0048] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
