Problems solved by technology

[0003] 1. It only has the function of pulling the mouth apart, but does not have the function of depressing the tongue. A tongue depressor must be used to press the patient's tongue
[0004] 2. Once the pulling force of the retractor is fixed, the positions of the upper and lower jaws are fixed. During the operation, the patient's mandible will exert force unconsciously, but because the position of the mandible is fixed, the patient feels uncomfortable. Comfortable
[0005] At the same time, the applicant found that all the existing oral expansion devices have not seen a device that can control the opening and closing of the oral cavity at a relatively long distance.

Abstract

The invention discloses an oral cavity dilator. The two ends of the outer side of an upper opening plate and the two ends of the outer side of a lower opening plate are each provided with two tooth pads; one ends of the upper opening plate and the lower opening plate are connected through two movable frames A, the other ends of the upper opening plate and the lower opening plate are connected through two movable frames B and a V-shaped connector, one ends of the two movable frames A are fixedly connected with one ends of the upper opening plate and the lower opening plate respectively, the other ends of the two movable frames A are connected through a connecting ring, the two movable frames B are arranged in a crossed mode, one ends of the two movable frames B are fixedly connected with one ends of the upper opening plate and the lower opening plate, and the other ends of the two movable frames B are connected with the inner side faces of the upper opening plate and the lower opening plate in a sliding mode; a traction steel wire is connected to the crossing point of the two movable frames B, a soft connection rod is installed at the front end of the V-shaped connector, the traction steel wire penetrates through the center of the V-shaped connector, and the soft connection rod is connected with a traction steel wire storage box. The oral cavity dilator can remotely control opening and closing of teeth, so that the oral cavity is in a movable open state; besides, the oral cavity dilator has a tongue pressing function and is convenient to use.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an oral dilator. Background technique [0002] In the operation of intraoral restoration, it is usually necessary to use an oral distraction device to stretch the oral cavity and fix it. Most of the mouth stretching devices currently used in clinical practice are pull hooks. During use, the upper and lower jaws are pulled apart by the upper and lower hooks, so that the mouth can be stretched. The disadvantage of this pull hook is: [0003] 1. It only has the function of pulling the mouth apart, but does not have the function of depressing the tongue. A tongue depressor must be used to press the patient's tongue. [0004] 2. Once the pulling force of the retractor is fixed, the positions of the upper and lower jaws are fixed. During the operation, the patient's mandible will exert force unconsciously, but because the position of the mandible is fixed, the patient feels uncomfo...
