Description

A needle cleaning device and its working method

technical field

The invention relates to a bur cleaning device and a working method thereof, belonging to the technical field of oral clinical medical equipment.

Background technique

The bur is a consumable appliance used by stomatologists. It is a small steel needle consisting of a needle head and a needle handle. It can be inserted into high and low speed mobile phones and used to help stomatologists open pulp, prepare teeth, adjust dentures, etc.

There are two main ways for dental burs to cause cross-infection: one is the surface contamination caused by the burs contacting the patient's saliva, blood, and debris during the operation in the oral cavity; microbes, etc. Because the burs are operated in the patient's mouth, they often come into contact with saliva, blood, and mucous membranes. There are many outpatients and high mobility in the dental clinic. The usage rate and turnover rate of the burs are high. How to clean the burs efficiently and quickly to better avoid cross-infection It is one of the important contents of dental care.

The choice of disinfectant in oral clinic is relatively strict, and it is necessary to choose a disinfectant with good sterilization effect, less irritation and less corrosion to metals. Currently, chemical disinfectants such as 20mg/L glutaraldehyde are used for the disinfection of burs. The traditional cleaning method is to first sterilize the surface of the used bur by soaking it for 30 minutes. The disinfectant is 2% glutaraldehyde. After soaking, use a toothbrush with a small head to clean the texture of the bur, and finally rinse it with water. The plan issued by the Ministry of Health clearly mentions that all instruments that come into contact with the human body must be cleaned and disinfected with an ultrasonic cleaner to achieve good cleaning results and improve cleaning speed.

Chinese patent document (Application No. 201520908191.1) discloses a cleaning net for an ultrasonic machine in the dental department, including two cleaning nets with one end open and two handles. The cleaning net is provided with small and dense mesh holes, and the two handles are respectively connected by elastic parts and The two cleaning nets are connected. When no external force acts on the handle, the openings of the two cleaning nets contact each other and are in a closed state. When an external force acts on the handle, the openings of the two cleaning nets are separated from each other and are in an open state. Chinese patent document (Application No. 201420375750.2) discloses an ultrasonic cleaning device for oral medical instruments, by setting multiple sets of corresponding vertically downwardly extending positioning slots on the inner walls of both sides of the cleaning tank, and each set corresponds to A support frame for hanging the net basket is inserted between the positioning slots of the support frame. The support frame for hanging the net basket is a frame structure composed of two columns and multiple beams. The space for holding the net baskets of medical instruments, each of the net baskets holding medical instruments is suspended on the beam through the provided hooks, and the two columns of the support frame are respectively matched with the positioning slots to form the positioning of each support frame, The net baskets for containing the medical instruments suspended on each supporting frame are located in the cleaning tank for comprehensive management of various medical instruments. In the two schemes, dental drills and burs are put into the cleaning net and then put into an ultrasonic machine for cleaning to avoid leakage of the drills and burs. However, this solution is still based on the current cleaning method using a large ultrasonic machine. The cleaning method is single, and the cleaning effect is easily affected by the cleaning net and stacking.

Currently there is no professional cleaning device for oral burs.
