Description

Description Handpiece for dental cutting with TV camera and visual recognition device

The present invention provides a dental cutting handpiece with a television camera, which allows a dentist to proceed with treatment while checking a video image of a tooth cut in real time by attaching a television camera to a part of the dental cutting handpiece. About. Background art

Conventionally, handpieces for dental cutting have been supplied with energy from a motor for power or pressurized air energy to obtain power from the motor, so that water is injected with air to increase heat generation during cutting and cutting efficiency. Water was mixed and supplied, and there was a built-in light to cut invisible parts that would be shadowed by the operating light, and the surgeon would check the teeth or look directly through the mirror.

First, conventional dental cutting handpieces are mainly used for cutting, and when observing the state of cutting, the power supply is stopped and the dental cutting handpiece is removed once outside the oral cavity. I had to check the condition of the tooth each time by looking at the dental mirror or directly. For this reason, complicated operations must be repeated many times in one treatment, leading to medical accidents, stress, wasteful treatment time, and excessive posture when the dentist faces directly. Indirectly, it put a burden on lung function and heart function. Second, it was difficult for conventional dental cutting hand beads to easily know that they had approached the tooth nerve when cutting soft dentin in the fossa. Third, _{conventional;} in dental cutting handpiece, leaving the record reflects and obvious task of root canal mouth during working Ya抜踺tooth-shaped in configuration of the cutting direction on the monitor screen in real time Could not.

Therefore, the first object of the present invention is to make it possible to easily visually recognize the state of a tooth being cut during tooth cutting treatment without resorting to complicated procedures.

The second purpose is to distinguish between hard dental tissue and soft tissue.

The third purpose is to record the condition of tooth formation and cutting during the recovery.

A fourth object of the present invention is to easily enable the above-mentioned first to third objects in an existing dental cutting handpiece. Disclosure of the invention

The present invention, for the first object, employs a method in which a television camera is attached to the tip of a dental cutting hand bead and a dentist can perform treatment while watching the display screen in real time while cutting teeth. . For the second purpose, use a TV camera attached to the toothpiece for dental cutting as an infrared camera to measure the temperature distribution of the hard tissue of the teeth, the temperature distribution of the gingival surface, and the temperature of the pulp in the deep and shallow layers of the fossa. We adopted a method of accurately confirming changes visually.

For the third purpose, a method was adopted that allows input to the operator's display screen, as well as to the patient's monitor television and to a DVD / video / computer for recording.

For the fourth purpose, a TV camera was attached to an existing dental cutting handpiece using a holder. P2003 / 010813
