Description

Technical Field

[0001] The utility model relates to the technical field of spreaders, and more specifically, to an oral treatment spreader. Background Art

[0002] A spreader is a medical device that spreads and fixes the patient's oral cavity to facilitate treatment by doctors. It is mostly used for oral treatment or gastrointestinal function testing and treatment. Existing spreaders are mostly pliers-shaped and large in size. After the oral cavity is spread, the handle of the spreader is exposed, which will hinder the doctor's examination and diagnosis.

[0003] According to Chinese utility model publication number CN217162074U, a mouth stretcher for oral treatment with lighting effect is disclosed, including a main rod, a connecting rod and a base. One end of the two groups of main rods is installed with a stretching bracket, and the inner side of one group of main rods is penetrated and installed with a reset bolt. The utility model compensates for the influence of insufficient light inside the oral cavity by installing a lighting lamp. The lighting lamp is installed on the inner side of the base through the thread opened on the rear end lamp body. The front end outer wall of the lamp body is sleeved with a fixing ring, which is used for positioning to prevent the lamp body from excessively entering the interior of the base and affecting use. However, the stretcher with this setting is relatively large in size. After the oral opening is completed, the handle of the stretcher is exposed to the outside, which will hinder the doctor's examination and diagnosis. Therefore, in view of this problem, how to design an oral treatment stretcher has become a problem that we currently need to solve. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an oral treatment expander. By setting a first support member and a first fixed plug plate, the present application sets the handle part and the expansion part to be separable. When the handle is used for expansion, the first support member and the second support member are gradually flipped and extended, and the first fixed plug plate is engaged with the inner side of the fixed tooth groove to complete the fixation. At this time, the handle part can be removed to reduce the volume to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oral treatment expander, comprising a expander lower part, the top of the expander lower part is hinged to a first support part, a fixed tooth groove is provided on the inner side of the first support part, the interior of the expander lower part is slidably connected with a first sliding part, the first sliding part and the first support part are arranged in a close-fitting state, the interior of the first sliding part is slidably connected with a first fixed plug plate, the first fixed plug plate is slidably connected to the interior of the expander lower part, a first spring is provided on one side of the first sliding part, the first spring is fixedly installed inside the expander lower part, the interior of the expander lower part is slidably connected with a limit rod, the first fixed plug plate is slidably connected to the outer side of the limit rod, a transmission plate is fixedly installed on one end of the limit rod, and one end of the first support part is hinged to the second support part.

[0012] Technical effects and advantages of the utility model:

[0013] 1. The utility model provides a first support member and a first fixed plug plate, and provides a handle portion and a spreading portion in a separable manner. When spreading the mouth by the handle, the first support member and the second support member are gradually turned over and extended, and the distance between the spreader lower member and the spreader upper member is extended, so as to spread the patient's oral cavity. The first support member and the second support member are fixed by the first fixed plug plate and the second fixed plug plate. At this time, the arm can be removed by separating the columnar spreading member from the inside of the spreader lower member, so as to reduce the volume of the spreader;

[0014] 2. The present invention provides a rubber sleeve. Unlike the traditional expander with a smaller contact area with the teeth, the shape of the expander lower piece and the expander upper piece in the present application can greatly increase the contact area with the patient's teeth, thereby avoiding the small contact area during the long-term oral expansion process. The small area will bring a greater burden to the teeth and increase the discomfort of the teeth. The bottom and top of the expander lower piece and the expander upper piece are both installed with rubber sleeves, so that soft contact with the teeth can be achieved, further improving the patient's comfort.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Refer to the instruction manual Figure 1-4 ,like Figure 1 As shown, an oral treatment expander according to an embodiment of the utility model comprises a expander lower part 1, as shown Figure 2 As shown, the top of the expander lower part 1 is hinged to the first support part 2, and a fixed tooth groove 3 is provided on the inner side of the first support part 2. The lower part 1 of the expander is internally slidably connected with the first sliding part 4, and the first sliding part 4 is arranged in a close-fitting state with the first support part 2. The first sliding part 4 is internally slidably connected with the first fixed plug plate 5, and the first fixed plug plate 5 is slidably connected to the inside of the expander lower part 1. A first spring 6 is provided on one side of the first sliding part 4, and the first spring 6 is fixedly installed inside the expander lower part 1. The lower part 1 of the expander is internally slidably connected with a limiting rod 7, and the first fixed plug plate 5 is slidably connected to the outer side of the limiting rod 7. A transmission plate 8 is fixedly installed at one end of the limiting rod 7, and one end of the first support part 2 is hinged to the second support part 9, and one end of the second support part 9 is hinged to the expander upper part 12, and the upper part 12 of the expander is internally slidably connected with the second sliding part 10.

[0022] It should be noted that, when the patient's oral cavity needs to be opened, the opener lower member 1 and the opener upper member 12 are placed in the patient's mouth and bitten, and the columnar opener 15 is inserted into the opener lower member 1 by grasping the handle 17. When the columnar opener 15 enters the opener lower member 1 and contacts the guide member 14, the guide member 14 descends and the second spring 13 contracts, and drives the first fixed plug plate 5 to descend and separate from the fixed tooth groove 3. At this time, the handles 17 on the upper and lower sides can be pressed to drive the connecting rod 16 to drive The columnar expansion member 15 expands the expander lower member 1 and the expander upper member 12. As the distance between the expander lower member 1 and the expander upper member 12 increases, the first support member 2 and the second support member 9 gradually flip over to a vertical state. At this time, the first support member 2 gradually loses the limit on the first sliding member 4, so that the first spring 6 contracts and drives the first sliding member 4 to slide to one side, thereby maintaining contact with the first support member 2. After being expanded to a suitable position, the columnar expansion member 15 is slowly separated from the guide member 14. After the guide member 14 gradually loses the limit of the columnar spreader 15, the second spring 13 will be stretched to cause the transmission plate 8 to rise, and then the first fixed plug plate 5 will be driven to rise through the limit rod 7, so that the first fixed plug plate 5 is inserted into the inner side of the fixed tooth groove 3 to complete the limit of the first support member 2, and the second fixed plug plate 11 simultaneously limits the second support member 9, so that the distance between the spreader lower member 1 and the spreader upper member 12 will not be shortened. At this time, the columnar spreader 15 can be taken out from the inside of the spreader lower member 1 and the spreader upper member 12, and the patient's oral cavity is maintained open only by the spreader lower member 1 and the spreader upper member 12 after fixation, so as to achieve the purpose of reducing the volume of the spreader, so that medical staff will not be hindered by the spreader when treating the patient, and at the same time, the spread distance between the spreader lower member 1 and the spreader upper member 12 is adjustable, which is suitable for different patients.

[0023] Further, such as Figure 2 As shown, the second sliding member 10 is arranged in a close-fitting manner with the second supporting member 9, the second sliding member 10 is slidably connected with the second fixed plug plate 11 inside, and the transmission plate 8 is slidably connected to the inside of the opener lower member 1, as shown in FIG. Figure 3 As shown, a second spring 13 is provided at the bottom of the transmission plate 8, and the second spring 13 is fixedly installed inside the lower member 1 of the spreader. A guide member 14 is fixedly installed at one end of the second spring 13, and the guide member 14 is slidably connected to the inside of the lower member 1 of the spreader. A columnar spreader 15 is inserted into the inside of the lower member 1 of the spreader, and the columnar spreader 15 is arranged in a close fit with the guide member 14. A connecting rod 16 is fixedly installed on the outside of the columnar spreader 15, as shown in FIG. Figure 4 As shown, a handle 17 is fixedly mounted on one end of the connecting rod 16 , and a rubber sleeve 18 is fixedly mounted on the top of the spreader upper member 12 .

[0024] It should be noted that, unlike the smaller contact area between the traditional stretcher and the teeth, the shape of the stretcher lower part 1 and the stretcher upper part 12 in the present application can greatly increase the contact area with the patient's teeth, thereby avoiding the smaller contact area during the long-term oral stretching process, which will bring a greater burden to the teeth and increase the discomfort of the teeth. In addition, the bottom and top of the stretcher lower part 1 and the stretcher upper part 12 are installed with rubber sleeves 18, so as to achieve soft contact with the teeth and further improve the comfort of the patients.
