Description

A root canal washing integrated device and washing method technical field

The invention relates to an integrated root canal cleaning device and a cleaning method, belonging to the clinical technical field of root canal treatment.

Background technique

The rinsing device for root canal treatment on the market has the following disadvantages: 1. In the root canal rinsing process, it needs to be divided into three steps to complete: 1) after the tooth pulp is opened, the solution is injected through the syringe needle; 2), through the rinsing device Shake; 3) Inject the solution through the syringe to rinse. The above process needs to be repeated several times. Because after the vibration and agitation, if the debris is not washed immediately, the debris will continue to settle due to gravity. If it is stuck in the root tip, it will be difficult to remove it in the next rinse, and it is easy to cause root damage. Canal inflammation, severe cases will lead to failure of root canal treatment, the tooth has to be pulled out; 2. The process of root canal washing needs to be completed in several steps, and shaking and washing are separated, which will make it inconvenient for doctors and nurses to operate and cumbersome. 3. The volume of the syringe is limited. If you want to use more solution, you need to use a larger syringe, which is very inconvenient to operate in the mouth, and the patient will choke on too much solution in his mouth, causing medical accidents; if you repeatedly pump the solution through the syringe It will allow impurities to be stored in the pulp cavity for too long. 3. The oscillator for root canal treatment currently on the market is an ultrasonic oscillator: 1) The needle of the ultrasonic oscillator is a metal structure, which causes a shutdown after the needle is blocked; 2) The needle of the ultrasonic oscillator is a metal structure, which hits the inner wall of the root canal Easy to break, even if the operator is skilled, the patient's head movement will cause the needle to hit and cause the needle to break, for example, the patient's cough will cause the head to shift; and the broken needle is extremely difficult to remove, which brings great harm to the patient and the doctor. It is very inconvenient, and even affects the treatment of patients, causing physical and mental harm, and has a high risk; 3) Ultrasonic washing has no drug spraying function, which cannot solve the problem of drug spraying. Replacement of needles or application of drugs by other means results in long treatment time and cumbersome treatment procedures ; 4) The main working parts of the root canal oscillator are divided into two parts: the drive structure of the root canal oscillator and the root canal needle. The vibration intensity of different root canal oscillators can be flexibly adjusted manually, but it is difficult to thoroughly clean the root canal in the prior art Infectious substances, as well as the elimination of residual bacteria and toxins, therefore also need to improve the effect of root canal irrigation and treatment.
