Detailed Description

The present utility model will be further described with reference to the following examples in order to better understand the technical solutions of the present utility model and to make the above features, objects and advantages of the present utility model more clearly understood. The examples are only for illustrating the present utility model and are not intended to limit the scope of the present utility model.

As shown in fig. 1 to 4, the present utility model includes: a lifter 1, a support column 2 and an upper support plate 3,

the lifter 1 is composed of two support plates 11, a reset spring is arranged in the intersection, each support plate 11 comprises a front support plate 111 for supporting gums and a rear clamping plate 112 for clamping teeth, and the reset spring utilizes elasticity to promote the rear clamping plate 112 to clamp at one end far away from the front support plate 111;

in use, the front support plate 111 is compressed by the forceps to allow the return spring to retract, and the rear clamping plate 112 is opened and placed into the crevices of the teeth and gum. The bottom surface of the front support plate 111 is far lower than the bottom surface of the rear clamping plate 112, so that the rear clamping plate 112 remains exposed to the outside after the front support plate 111 is put in.

After the release, the return spring is reset, the rear clamping plate 112 clamps the teeth to complete fixation, the front supporting plate 111 supports the gingiva, and the circular arc structure can play a role in auxiliary positioning.

To prevent the patient's upper and lower jaws from closing, the combination is performed by setting up the support columns 2 and upper support plates 3.

Two ends of the support column 2 are respectively connected with the lifter 1 and the upper supporting plate 3 in a limiting manner, so that a supporting effect is achieved.

The cross section of the upper supporting plate 3 is concave, the whole body is arc-shaped, and the inner groove is used for engaging with the upper teeth.

In order to prevent the return spring from falling off, the whole return spring is positioned in the lifter 1, two ends of the return spring are respectively connected with two support plates 11, and the two support plates 11 have a certain pretightening force by twisting the return spring.

In order to facilitate the forceps taking of the surgical forceps, the outer side wall of the front supporting plate 111 is provided with a clamping groove, and the inside of the clamping groove is provided with anti-skidding patterns.

In order to prevent the knock-out of the lifter 1, the bottom of the front support plate 111 is further provided with an insert plate which is positioned between the gums and the gums after being inserted.

In order to cater for the oral cavity sizes of different patients, the support column 2 is composed of a head column, a tail column and a plurality of connecting columns, one end of each connecting column is provided with an embedded groove, the other end of each connecting column is provided with an embedded plate, one end of the head column is provided with the embedded groove, the other end of the head column is connected with the side wall of the opener 1 through an inserting rod, one end of the tail column is provided with the embedded plate, and the other end of the tail column is in limiting connection with the upper supporting plate 3 through the inserting rod.

Before operation, the size between the upper teeth and the lower teeth of a patient is measured, and enough connecting columns are selected for mounting and supporting, and the head column and the tail column are respectively fixed with the lifter 1 and the upper supporting plate 3 in an embedded mode. The overall length of the support column 2 is slightly smaller than the measured size of the patient.

In operation, the involuntary upper and lower jaws of the patient can not lead the insertion rod to fall off, and meanwhile, the support column 2 presents a curve shape in the oral cavity of the patient, so that the whole length of the support column 2 is slightly smaller than the measurement size of the patient. In order to prevent breakage of the support column 2, the support column 2 is cemented carbide.

In order to reduce the movement of the upper support plate 3 and wear in the mouth of the patient, the upper support plate (3) is padded.
