Dental root nerve cleaning device in the department of stomatology

Abstract

The invention discloses a stomatological department tooth root tooth nerve cleaning apparatus. Tooth nerves are spirally ground by a plurality of spiral plates, are clamped by the adjacent spiral plates, and guiding bars are combined to guide out the root nerves. The tooth nerve cleaning apparatus is characterized in that a connecting ring is placed at one end of an inner sleeve, a spiral ring isplaced at the other end of the inner sleeve, the connecting ring is connected with the spiral ring through the plurality of guiding bars, the guiding bars are circumferentially distributed on the outer wall of the inner sleeve, one ends of the guiding bars are laminated to the connecting ring, the other ends of the guiding bars extend along the axial direction of the inner sleeve to half of the inner sleeve, the guiding bars extend along the spiral ring and are laminated to the spiral ring, the adjacent two guiding bars are combined to form a guiding groove, a plurality of flow guiding holes are correspondingly placed in the direction guiding grooves, and are communicated with the internal of the inner sleeve, and one ends of the plurality of spiral plates are placed on the connecting ringin an equal angle manner.

Description

Technical field [0001] The invention relates to a tooth root and tooth nerve cleaning device in the stomatology department, which relates to a device for cleaning the tooth nerves killed in the root canal during root canal treatment in the stomatology department, and belongs to the field of medical equipment. In particular, it relates to a dental nerve cleaning device that performs spiral grinding through a plurality of spiral plates, clamps the dental nerve through two adjacent spiral plates, and cooperates with a guide strip to lead the dental nerve out. Background technique [0002] At present, when the dental root is treated in the dentistry, it is necessary to clean the dental nerve in the root canal, peel the necrotic dental nerve from the root canal, and use drills, files and other medical instruments to clean the inner wall of the root canal. , To remove the killed dental nerve. During the cleaning process, the drill bit and cleaning file need to be rotated to take out th...

Problems solved by technology

[0002] At present, when treating the root of a tooth in the department of stomatology, it is necessary to clean the tooth nerve in the root canal, strip the necrotic tooth nerve from the root canal, and use medical instruments such as drills and files to clean the inner wall of the root canal , to remove the killed tooth nerve. During the cleaning process, it is necessary to rotate the drill bit and the cleaning file to take out the tooth nerve. It will cause the tooth nerve to be pulled off, or squeezed and attached to the root canal wall, which will affect the cleaning. There are two kinds of manual and automatic cleaning. Manual cleaning is carried out by the medical staff through the cleaning file in the root canal, and then Rotary cleaning, low cleaning efficiency, high operating requirements for medical staff, automatic cleaning through electric impact drill to clean the tooth nerve in the root canal, through high-speed mechanical rotation, winding between the tooth nerve and then cleaning and pulling out, the drill bit is a single helix structure, there will be back swing when rotating, the service life of the drill bit is low, and the back swing will break the drill bit, causing safety hazards;

[0003] Publication No. CN106456300A discloses a device and method for cleaning teeth and root canals which may include a chamber having an access port which places the chamber in contact with the tooth when the chamber is coupled to the tooth The treatment area is in fluid communication, a fluid motion generator can be coupled to the chamber, the fluid motion generator can be configured to direct fluid across the access port to generate fluid motion in the chamber, the invention communicates through the chamber and the dental treatment area, and then through the generator The flow of the fluid is changed, but the fluid enters from the tooth treatment area, contacts and rotates in the root canal, and the kinetic energy of reaching the cusp is attenuated. During the cleaning process, a large amount of foreign matter is washed to the cusp, resulting in accumulation of foreign matter. Cause other serious, so this invention is not suitable for root canal cleaning
