The underjaw locating device comprises a supporting rod, a main arm, a denture winding mechanism and an inserting buckle, wherein the main arm is fixed to the upper end of the supporting rod, and the denture winding mechanism and the inserting buckle are arranged at the two ends of the main arm respectively; the denture winding mechanism comprises a support arm, a rotating shaft, a clockwork spring, a denture belt, a shell, an outlet and an inserting head, the support arm is fixedly connected with the main arm and connected with the rotating shaft, the clockwork spring is arranged on the rotating shaft, the denture belt is wound around the clockwork spring, the inserting head is fixed to one end of the denture belt, the shell is arranged outside the denture belt, and the outlet is formed in the bottom of the shell. According to the underjaw locating device for dental department CT, the denture belt can be tightened regardless of the head size of a patient to achieve the good tightening and fixing effects, and the underjaw locating device is easy to operate, avoids that the patient is caused to feel nervous and facilitates underjaw location of the patient for accurate detection and imaging.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a dental CT mandibular positioning device. Background technique [0002] Modern people do not pay attention to the maintenance of oral hygiene in daily life, and they are prone to common problems such as dental caries, tartar, dental plaque, bleeding gums, dentin sensitivity, unclean teeth and bad breath. If these problems are paid attention to, they are likely to cause cardiovascular diseases and diabetes etc. With the improvement of the quality of life, everyone's awareness of protection has increased, and they are constantly paying attention to the protection of teeth, and do oral CT regularly. Oral CT can reflect the tissue situation from a three-dimensional perspective, and can find subtle lesions that cannot be found in the projection angle of oral X-ray films; its three-dimensional reconstruction effect can accurately evaluate the bone tissue and mandibular joint con...

Problems solved by technology

[0003] At present, when patients use dental CT detection and imaging, the mandible needs to be positioned. When the mandible is positioned, it needs to be adjusted continuously according to the patient's head shape to ensure a good tightening and fixing effect. Such positioning operation is extremely inconvenient and easily causes the patient to be nervous.
