Description

Suspension type movable oral CT device

Technical Field

The utility model relates to a dental medical treatment CT imaging technical field, in particular to mobilizable oral cavity CT device of suspension type.

Background

CT (Computed Tomography), which is an electronic Computed Tomography, scans a layer of a certain thickness of a human body part with X-rays, converts the attenuated X-rays penetrating the layer into visible light by a detector, converts the optical signal into an electrical signal, converts the electrical signal into a digital signal by a digital-to-analog converter, and finally processes the digital signal into an image by a computer.

In the field of medical radiographic imaging, the conventional oral disease examination means is an oral X-ray film, and general root inflammation, tooth fracture and bone conditions can be well reflected. However, it can only perform projection from a fixed direction, some lesions are difficult to be found due to the superposition of tissues, and a complete treatment scheme and a diagnosis basis cannot be made due to the limitation of visual field and operation, the overlapping of images and the like. Oral cavity CT (CBCT, cone beam CT), because it can display the lesion tissue and the normal tissue structure from a three-dimensional angle, avoids the defects of two-dimensional plane, such as image overlapping of normal tissue and organ, image distortion and deformation caused by the change of projection angle, and is widely used in clinic.

The oral cavity CT examination image can rotate at will in multiple sections such as coronal position, sagittal position, axial position and 3D, meanwhile, the high-definition boundary can highlight details of anatomical structures with different densities, rich tissue structure information is provided, and the precision medical treatment and clinical level of the department of stomatology can be greatly improved. Therefore, the shoulder bears the need of clinical multi-disciplinary diseases, such as implantation, orthodontics, dental pulp, periodontal, temporomandibular joint, maxillofacial surgery and the like, and can assist various clinical diagnoses and treatments, preoperative examinations and targeted treatments.

The oral cavity special CT equipment is adopted by more and more hospitals, has smaller volume, lower equipment cost and use cost than the whole body CT, but has the advantages of clearer and more accurate whole body CT. The imaging irradiation range of the oral CT is reduced, so that the radiation exposure of a human body is obviously reduced compared with the whole body CT.

At present, oral CT mainly performs image shooting before and after treatment of a patient, and is used for disease diagnosis and treatment scheme formulation. If a clear image of the focus needs to be obtained in the treatment process, a doctor needs to clean the focus of a patient and an operation environment around the patient to enable the patient to leave a dental operation chair to go to a radiation room to complete scanning, so that great waste of doctor-patient resources is caused by repeated cleaning preparation and waiting time of CT scanning. Taking common root canal therapy as an example, more than one CT scan is needed in each root canal therapy operation to confirm the root canal therapy state, wherein the CT scan time accounts for 25-30% of 1-1.5 hours in the whole treatment process. Because the oral cavity CT equipment is fixed and can not be flexibly moved, the requirement that the patient does not leave the operation working position in the operation can not be met. In addition, the fixed oral CT cannot satisfy the requirement of moving and switching among a plurality of dental treatment stations in an operating room. The above limitation results in low utilization rate of equipment, and cannot meet the imaging shooting requirement of a patient for dentistry in operation, and the application scenario is limited.
