Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a novel mouth opener. Background Art

[0002] An opener is a tool used to expand the oral cavity, making it easier for dentists to treat patients' oral diseases. There are many types of openers, among which silicone openers are the most common. However, this type of opener is small in size, not easy to remove or insert, and there is a risk of displacement and falling off, resulting in patients' pharyngeal reflex and even accidental swallowing without suction. Especially when used by children, if the children do not cooperate, there is a risk of accidental swallowing. The openers currently used in the treatment of children's oral dental diseases are relatively inconvenient for doctors to open and operate, and there are only three degrees of opening, which is relatively limited. At the same time, the occlusal part of traditional therapeutic openers placed in the mouth is made of metal and does not have a buffering protection device. Long-term expansion can easily cause damage to the patient's internal oral cavity, threatening the patient, especially for infants and young children. Since the use of an opener may damage the oral mucosa when the teeth of infants and young children have not all erupted, the use of an opener may cause damage to the oral mucosa.

[0003] Therefore, in order to solve the above technical problems, the utility model provides a novel opener. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of mouth opener which can be adjusted autonomously according to the opening demand, can provide buffering during occlusion, reduce damage to the occlusal part and the inside of the oral cavity, and can prevent the support pad from falling off.

[0005] In order to achieve the above-mentioned technical effect, the utility model is realized through the following technical scheme: a new type of opener, including an expansion mechanism and a self-locking mechanism, characterized in that: the expansion mechanism includes a first clamp, a rotating seat fixedly installed in the middle of the first clamp, a second clamp rotatably hinged on the rotating seat, a handle fixedly installed at one end of the first clamp and the second clamp, a mounting rod arranged at the other end of the first clamp and the second clamp, a limiting mechanism arranged at the end of the mounting rod, and an arc-shaped tooth groove movably sleeved on the outside of the mounting rod; the self-locking mechanism includes a fixed box fixedly installed at the end of the rotating seat, a self-locking spine bar fixedly installed at the rear end of the fixed box, a self-locking device slidably installed on the outside of the self-locking spine bar, and a first connecting seat and a second connecting seat respectively rotatably connected to both sides of the self-locking mechanism; the ends of the first connecting seat and the second connecting seat are respectively rotatably connected to the first clamp and the second clamp.

[0006] Furthermore, the first pliers and the second pliers have the same structure, both comprising a pliers body and a rotating ring arranged in the middle of the pliers body; the rotating seat comprises a rotating column, threaded columns symmetrically arranged at both ends of the rotating column, and a fixed rod fixedly installed at the top of the threaded column at one end; the length of the rotating column is adapted to the total thickness of the first pliers and the second pliers superimposed; the fixed box is installed at the end of the fixed rod; the inner diameter of the rotating ring is adapted to the diameter of the rotating column.

[0007] Furthermore, arc-shaped protrusions are symmetrically arranged on the upper and lower sides of the installation rod; and guide grooves are symmetrically arranged on the left and right sides of the installation rod.

[0008] Furthermore, the arc-shaped tooth socket is made of medical silicone material; a mounting groove is provided through the middle of the arc-shaped tooth socket, an arc-shaped groove whose size is adapted to the arc-shaped protrusion is provided inside the mounting groove, and guide blocks adapted to the guide groove are provided on both sides of the mounting groove; the arc-shaped tooth socket is installed on the mounting rod by engaging the arc-shaped groove with the arc-shaped protrusion.

[0009] Furthermore, a limiting ring is provided on the handle; and the outer wall of the limiting ring is covered with a rubber sheath.

[0010] Furthermore, the self-locking device includes a sliding box slidably mounted on the outside of the self-locking ratchet, a self-locking hole arranged at the upper end of the sliding box and extending through the self-locking ratchet, a self-locking tooth rotatably connected to the middle of the self-locking hole, a plate fixedly mounted on the upper end of the self-locking tooth, and a self-locking spring connecting the lower end of the plate and the outer wall of the sliding box.

[0011] Furthermore, the limiting mechanism includes a limiting groove arranged at the end of the mounting rod, a limiting block rotatably connected to one side of the top end of the limiting groove, and a limiting spring fixedly connecting the bottom surface of the limiting block and the bottom surface of the limiting groove.

[0012] The beneficial effects of the utility model are:

[0013] The utility model hinges the first clamp and the second clamp to each other through a rotating seat, and installs a grip at one end of the first clamp and the second clamp, which is convenient for medical personnel to hold. At the same time, a limiting ring is provided on the grip, which is convenient for medical personnel to exert force when using, and quickly open and close the first clamp and the second clamp. By covering the outer wall of the limiting ring with a rubber sheath, the damage to the skin of the medical personnel by the limiting ring during use is reduced, and the comfort of use is improved. By arranging an arc-shaped tooth groove made of silicone material on the mounting rod, the patient's teeth can be placed on the arc-shaped groove on the mounting rod at the rear end of the first clamp and the second clamp when in use. Inside the alveolar socket, when the patient bites, the arc-shaped alveolar socket deforms with the bite force to achieve buffering, reduce stimulation and damage to the teeth in the arc-shaped alveolar socket, and at the same time, the arc-shaped alveolar socket can cover the teeth to prevent the teeth from falling out of the arc-shaped alveolar socket during treatment and causing the mouth to mesh; by setting a self-locking mechanism, when the first and second pliers are opened, the opening angles of the first and second pliers can be automatically fixed through the cooperation of the self-locking device and the self-locking spine, so that the device can adjust the opening degree according to specific needs to avoid interference with treatment caused by too large or too small opening angles;

[0014] Compared with the existing opener, the utility model has an arc-shaped tooth socket that can be installed on the mounting rod through the mounting groove, the arc-shaped groove and the arc-shaped protrusion and the guide groove of the mounting rod, so that the arc-shaped tooth socket can be replaced; at the same time, by setting the arc-shaped protrusion and the limiting mechanism, the arc-shaped tooth socket can be limited and fixed to prevent the arc-shaped tooth socket from falling off during use. At the same time, after pressing the limiting mechanism, the arc-shaped tooth socket can be pulled out and replaced, thereby reducing the risk of cross infection and improving the safety of use.
