High-speed turbine dental handpiece suitable for single-use with safety

Abstract

The invention provides a high-speed turbine dental handpiece suitable for single-use with safety. The handpiece comprises the following components: a head, a handle which is connected to the rear end of the head, a connector which is arranged at the rear end of the handle, and a snap ring which is used for fixing the handle and the connector; a sidewall of the connector is provided with a first fixing groove, a second fixing groove which is matched with the first fixing groove is arranged at the end of the handle, and an inner wall of the snap ring is provided with a projection which is matched with the first fixing groove and the second fixing groove; when a hoop of the snap ring is on the connector, the projection is embedded into the first fixing groove and the second fixing groove in order to limit and fix the handle and the connector. A plurality of modes are used for effectively preventing reuse of the dental handpiece suitable for single-use, the handpiece has a simple structure and can be conveniently dismounted, after usage, the handpiece can be conveniently dismounted and destroyed, and a disposable light emitting component can be used for simply and clearly checking whether the dental handpiece is used. 'One patient-one machine-single use' advocated by World Health Organization in the field of oral medical treatment is realized, and the problem of iatrogenic cross infection in the field of oral cavity is effectively solved.

Description

technical field [0001] The invention relates to a dental handpiece, especially a disposable and safe dental handpiece. Background technique [0002] Dental handpieces are necessary supplies for personal oral and dental surgery. At present, the disinfection methods of dental handpieces are complicated, the disinfection time is long, and the disinfection cost is high. In order to prevent cross-infection of various diseases, disposable dental handpieces have been produced on the market. However, some criminals recycle the used dental handpieces and reuse them after disinfection, which greatly affects the physical and mental health of patients. Disposable medical supplies have rules for destruction. For example, there are regulations on how many cuts need to be made to the length of disposable infusion tubes after use. Because the dental handpiece will generate a huge suction force when it stops at high speed, the virus and other harmful substances in the oral cavity will be su...

AI Technical Summary

Problems solved by technology

Disposable dental handpieces currently on the market do not have a reliable destruction structure. For example, the invention patent with the publication number "1887236" in the Chinese patent library and the invention name "Disposable high-speed turbo dental drill handpiece" mainly uses Permanent injection molding changes the product structure to reduce costs, and does not involve any anti-recycling and anti-suckback design points
