Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an oral tongue depressor. Background Technology

[0002] An oral tongue depressor is a medical device mainly used during oral examinations, treatments, and radiotherapy to help doctors better observe the internal structure of the oral cavity and reduce patient discomfort. Doctors need to use an oral tongue depressor to open the upper and lower jaws at a certain angle during radiotherapy for nasopharyngeal carcinoma, gingival carcinoma, and tongue cancer to facilitate treatment.

[0003] Before performing oral treatment, a tongue depressor is needed to open the patient's mouth to facilitate examination of the oral cavity. However, with existing tongue depressors, when the mouth is opened, the cheeks on both sides come into contact with the gums, which can easily obscure the gums. Therefore, when examining the patient's gums, the doctor needs to use tools to support the cheeks again, which is inconvenient. Therefore, this application provides a tongue depressor to meet this need. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an oral tongue depressor to solve the problem that existing oral tongue depressors cannot separate the cheeks on both sides of the mouth from the patient's gums when supporting the oral cavity, which makes it inconvenient to examine the patient's gums.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An oral tongue depressor includes a first support plate, a second support plate, an expansion mechanism, and an adjusting slider. An adjusting slide frame is provided at the top of the first support plate and the bottom of the second support plate. The adjusting slider is slidably sleeved inside the adjusting slide frame. The expansion mechanism includes a mounting plate. A first elastic sheet is mounted on the outside of the mounting plate and is fixedly sleeved on the outside of the adjusting slider. A second elastic sheet is provided on the inner wall of the first elastic sheet, and a support piece is provided on the outer wall of the second elastic sheet. The support piece is disposed between the two first elastic sheets, and one end of each support piece is connected to the bottom of a first elastic sheet. A first weakening groove is provided on the outer wall of the first elastic sheet, and a second weakening groove is provided on the inner wall of the first elastic sheet.

[0006] Optionally, the outer wall of the second elastic sheet is provided with two first crease grooves, and the inner wall of the second elastic sheet is provided with a second crease groove. The first crease grooves are located on both sides of the second crease groove and are symmetrical to each other.

[0007] Optionally, the top of the first elastic sheet is provided with two bending weakening grooves, which are located on both sides of the support sheet and are symmetrical to each other.

[0008] Optionally, a limit block is provided at the bottom of the first support plate, and an arc-shaped groove is provided inside the limit block. An arc-shaped plate is provided at one end of the second elastic sheet, and the arc-shaped plate is fixedly sleeved inside the arc-shaped groove.

[0009] Optionally, one end of the first support plate is provided with an arc-shaped plate, the arc-shaped plate is provided with a threaded sleeve, an adjusting screw is rotatably sleeved inside the threaded sleeve, the adjusting slider is provided with a connecting groove, and the mounting plate is provided with a placement groove.

[0010] Optionally, the adjusting screw is rotatably sleeved inside the placement groove, and one end of the adjusting screw is provided with a driving plate, which is rotatably sleeved inside the connecting groove.

[0011] Optionally, a connecting sleeve is provided at one end of the first support plate, and a connecting arc plate is provided at one end of the second support plate. A rotating rod is provided at the top of the connecting arc plate, and the rotating rod is rotatably sleeved inside the connecting sleeve.

[0012] Optionally, a limiting sleeve is provided at the other end of both the first support plate and the second support plate, and a limiting plate is fixedly sleeved on the outer wall of the limiting sleeve, and a dental arch is installed on the top of the limiting plate.

[0013] Optionally, the outer wall of the adjusting slider is provided with a limiting slide rod, the inside of the adjusting slide frame is provided with a limiting slide groove, and the limiting slide rod is fitted inside the limiting slide groove.

[0014] Optionally, the first elastic sheet, the second elastic sheet, and the support sheet are all made of plastic.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up an outward expansion mechanism, the first elastic sheet is supported to open outward under the action of the second elastic sheet and the support sheet. At the same time, under the action of the bending weakening groove, the first elastic sheet bends upward, which opens the cheeks on both sides of the patient's mouth outward, so that the inner sides of the cheeks on both sides are separated from the patient's gums. This facilitates the examination of the patient's gums and radiotherapy, and avoids the skin inside the mouth from obstructing the gums and affecting the examination of the gums.

[0016] By setting an adjusting slider and an adjusting screw, the position of the adjusting slider inside the adjusting frame is adjusted under the drive of the adjusting screw, which pushes the first support plate and the second cardboard to rotate outward around the rotating rod. Adjusting the opening angle of the first support plate and the second support plate can open the upper and lower jaws to a certain angle. Then, by adjusting the position of the adjusting slider inside the adjusting frame, the opening requirements of the oral tongue depressor at different angles can be met. Attached Figure Description
