Root canal treatment robot and treatment method

Abstract

The invention provides a root canal treatment robot and a treatment method. According to the root canal treatment robot, aball head and a root canal treatment fiber are driven by an x-axis motion unitand a y-axis motion unit to move on xy planes, and the root canal treatment fiber is driven by a z-axis motion unit to move alonga zaxis while the root canal treatment fiber is driven by the a-axis motion unit to rotate around the zaxis. Through the robot, the four-degree-of-freedom control of the root canal treatment fiber is achieved, thereby achieving various motion modes of the root canal treatment fiber by using a micro-robot to implement root canal treatment,problems in the root canal treatment process are solved by manual methods, and the labor cost of the root canal treatment is reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a root canal treatment robot and a treatment method. Background technique [0002] Root canal treatment is the treatment of choice for endodontic and periapical diseases. The principle of root canal therapy is to remove most of the infection in the root canal by mechanical and chemical methods, and to prevent the occurrence of periapical lesions or promote the healing of periapical lesions that have occurred by filling the root canal and sealing the crown . It is one of the most basic operating techniques for dentists. According to the fourth national oral epidemiological survey report, the caries rate of 3-5 years old is 62.5%, and the number of missing and filling teeth is 3.35; the caries rate of 12-15 years old is 41.9%, and the number of caries and fillings is 1.04 , 35-44 years old have a caries rate of 89%, the number of caries and missing fillings is 4.54, 55-64 years o...

AI Technical Summary

Problems solved by technology

In the narrow space of the human oral cavity, the root canal preparation of a tooth with three root canals is completed by drilling and dredging the root canal by relying on the existing manual rolling and pulling or hand-held rotating nickel-titanium instruments or ultrasonic vibration, and the average It takes about an hour. If the root canal is blocked, sometimes it takes one or two hours to clear a root canal, which is time-consuming, laborious, inefficient, and easily leads to fatigue of the doctor, suffering from cervical spine, lumbar spine and other diseases; Caution may also cause fatigue and fracture of instruments, or artificial medical accidents such as side penetration, and inexperienced young doctors may also have incomplete treatment, which may easily lead to secondary infection, especially for some root canals with serious calcification, relying on existing methods Unable to dredge, and finally can only extract the affected tooth

[0004] In addition, the existing method of relying on human eye observation to find the root canal opening in the pulp cavity is also very backward, laborious, and should not be easily identified. Clinicians rely more on the feeling and touch of the hand. method, it is still time-consuming and labor-intensive, and there is still a mirror image deviation problem in the operation

Moreover, the price of a single microscope is hundreds of thousands of yuan, so it is difficult to fully popularize it in hospitals or clinics at all levels.

[0005] At present, the root canal treatment process generally requires four-handed operation. One patient needs to occupy the resources of two doctors and nurses, and the labor cost is relatively expensive.
