A cutting device for automatic tooth preparation in the oral cavity

Abstract

The invention discloses a miniature automatic dental-preparation cutting device in an oral cavity. The device comprises a motor drive component, an optical path component and a monitor component, wherein an X galvanometer oscillating motor and a Y galvanometer oscillating motor in the motor drive component are arranged on an oscillating motor mounting seat; a linear motor is fixed on a linear motor mounting seat through a screw; the linear motor mounting seat is fixed on a mounting bottom plate; an X galvanometer plate in the optical path component is adhered to the X galvanometer oscillating motor, and a Y galvanometer plate is adhered to the Y galvanometer oscillating motor; a focusing lens is arranged on a lens mounting seat through a screw ring; a beam combiner is fixed on a beam combiner mounting seat through a screw; an industrial lens in the monitor component is connected to a CCD (charge coupled device) image sensor. The device can be used for cutting a tooth to shapes of various preparation bodies required in clinical application, and performing para-oral real-time monitor, so that the operation safety can be further guaranteed.

Description

technical field [0001] The invention relates to the technical field of oral surgery instruments, in particular to a miniature automatic tooth preparation cutting device in the oral cavity. Background technique [0002] At present, in dental oral treatment, it is sometimes necessary to cut tooth hard tissues quantitatively. Turbine-driven dental handpieces are widely used in dentist clinics and medical laboratories around the world. Most dental handpieces include a handle part, at one end of the handle part The connector and at the other end the tool carrying the drive head, the connector provides the connection of the handset to the various air, water, light and electricity supply lines, which are usually combined in a so-called umbilical cord; The drive head houses the tool rotating part, which typically consists of a tool base or chuck and a motor or turbine rotatably mounted in the head for driving the chuck. [0003] In the existing technical solutions, the cutting of t...

Problems solved by technology

[0003] In the existing technical solutions, the cutting of the teeth by the dental handpiece uses the contact between the drive head and the teeth to complete the cutting work. Due to the shaking of the human hand and the narrow operating space in the oral cavity, the shape accuracy of the teeth after dental preparation (dental preparation) Depending on the doctor's clinical experience and technical level, the results of tooth preparation are uneven. In the actual work process, the surgical instruments generate a lot of noise, which also causes discomfort and tension to the patient. After each operation, the instruments have to be cleaned Overall cleaning and disinfection
