Problems solved by technology

[0004] In recent years, individual radiology technicians have tried to let patients bite cotton rolls or gauze balls to separate the palate and tongue. Because cotton rolls or gauze balls are soft in texture, they deform greatly when biting, and the palate and tongue are separated. Poor separation and poor image quality

Abstract

The invention belongs to the field of medical instruments, in particular to a tongue palate separation device when the oral CT is shot. The device is characterized in that two occlusal pads are arranged, the occlusal pads are H-shaped, a buccal side surface, a tongue palate surface and a separation pad are arranged, and the separation pad integrates the buccal side surface and the tongue palate surface together; the separation pad is provided with an upper tooth surface and a lower tooth surface for placing upper and lower back teeth when photographing is conducted; a spatula is fixedly connected with the tongue palate surface vertically and used for fixing a tongue body during shooting to prevent the tongue body from rising. The device is applied to CT or CBCT examination of goitre of tongue and palate, and the tongue and the palate are separated, thereby ensuring that the range of lesion can be clearly displayed during the shooting.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a tongue and palate separation device for shooting oral CT. Background technique [0002] In the narrow space of the oral cavity, the palate and tongue are anatomically close to each other. When the patient is in a resting state when taking oral CT, the lips are gently closed, the upper and lower teeth are slightly separated, and the surface of the palate is attached to the upper edge of the tongue. In the oral CT image taken at this time, the doctor cannot distinguish the soft tissue of the palate from the upper edge of the tongue. The tongue tissue is separated. [0003] When a lesion occurs in the palate or tongue of a patient, it is often necessary to take a CT scan of the oral cavity to judge the shape, scope and nature of the lesion. In clinical work, some radiologic technicians will instruct patients to keep their mouths open and tongues pressed in order to separate the ...
