Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a dental pad with mouth-opening function. Background Technology

[0002] Endoscopic mouthguards are tools frequently used in various endoscopic examinations. They are placed in the patient's mouth to keep the mouth open, creating a relatively open endoscopic passage to provide space for the endoscope to pass through.

[0003] However, in clinical applications, oral cancer patients often experience difficulty opening their mouths after surgery. Patients who have not received sufficient mouth-opening training may not be able to open their teeth to the required outer diameter of the endoscope, making it impossible for the endoscope to enter the oral cavity. In addition, their teeth may bite the endoscope tube, causing damage to the endoscope.

[0004] To address this, through clinical practice, we designed a dental pad with an opening function. By setting conical parts with external threads on both sides of the dental pad body, the two conical parts can be rotated to support the patient's upper and lower teeth, making it easy to place the dental pad body and the central sleeve. The central channel can easily pass through the endoscope, protecting the endoscope from being scratched by the teeth. Utility Model Content

[0005] The purpose of this invention is to provide a dental pad with an opening function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dental pad with mouth-opening function includes a dental pad body, a central sleeve at the bottom of the dental pad body, an endoscope insertion hole communicating with the central sleeve on the dental pad body, and an opening component on the dental pad body for supporting the patient's upper and lower teeth.

[0008] As a further preferred embodiment of the present invention: the opening assembly includes a rotating shaft rotatably disposed on both sides of the dental pad body, with a tooth-expanding cone located on both sides of the central sleeve fixedly connected to the bottom of the rotating shaft, and a handle fixedly connected to the upper end of the rotating shaft.

[0009] As a further preferred embodiment of this utility model, the surface of the tooth-expanding cone is provided with external threads.

[0010] As a further preferred embodiment of this utility model, both the dental pad body and the central sleeve are made of flexible plastic.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This dental splint has a simple structure and a scientifically sound design. It utilizes threaded cones on both sides to support the patient's upper body when needed.

[0013] When lowering the teeth, the dental retractor can be screwed into the patient's mouth by turning the handle, which can easily assist oral cancer patients in opening their mouths, facilitate the insertion of the endoscope, and avoid the problem of the patient's teeth biting the central cannula and endoscope tube. It is easy to operate and highly practical. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please refer to Figures 1-3. This embodiment provides a dental pad with mouth-opening function, including a dental pad body 1. A central sleeve 2 is provided at the bottom of the dental pad body 1. An endoscope insertion hole 3 communicating with the central sleeve 2 is provided on the dental pad body 1. In order to achieve the purpose of assisting oral cancer patients in opening their mouths after surgery, an opening component for supporting the patient's upper and lower teeth is provided on the dental pad body 1. Specifically, the opening component includes a rotating shaft 6 rotatably disposed on both sides of the dental pad body 1. The bottom of the rotating shaft 6 is fixedly connected to a tooth-expanding cone 4 located on both sides of the central sleeve 2. In order to better allow the tooth-expanding cone 4 to be screwed between the upper and lower teeth, an external thread 5 is provided on the surface of the tooth-expanding cone 4. A handle 7 is fixedly connected to the upper end of the rotating shaft 6. The tooth-expanding cone 4 is rotated by rotating the handle 7.

[0021] It should be noted that, as a conventional setup familiar to those skilled in the art, in actual processing and application, the dental pad body 1 and the central sleeve 2 are preferably integrally processed and both are made of flexible plastic material, so that the dental pad body 1 can produce a certain degree of bending when the retractor cone 4 is continuously rotated into the mouth; the material selection is a conventional technique familiar to the dental pad field.

[0022] Other conventional materials can also be used as substitutes, which will not be described in detail in this application; at the same time, the rotational connection between the rotating shaft 6 and the dental pad body 1 is also a conventional setting familiar to those skilled in the art. The rotation of the rotating shaft 6 can be achieved by designing a plastic bearing or a plastic sleeve on the dental pad body 1 and passing the rotating shaft 6 through the plastic bearing or plastic sleeve. Other conventional connection structures can also be used, which will not be described in detail in this application.

[0023] In clinical use, first insert the bottom of the two tooth-expanding cones 4 into the gap between the patient's teeth, then press in the tooth pad body 1 to stabilize the entire tooth pad, and turn the handle 7 to spirally press the tooth-expanding cones 4 into the patient's mouth, thereby opening the patient's teeth and achieving the function of assisting in opening the mouth. Finally, insert the endoscope through the endoscope insertion hole 1.

[0024] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0025] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
