High-degree-of-freedom connecting structure of root canal oscillating washer oscillating washing needle and oscillating washing method

Abstract

The invention relates to an oscillating washing needle and a high-degree-of-freedom connecting structure of a root canal oscillating washer and a root canal oscillating washing method, and belongs tothe technical field of root canal treatment equipment. The oscillating washing needle comprises a needle head, a ball joint and a connecting rod; a connecting rod of the oscillating washing needle isconnected with a spherical groove of an eccentric wheel through the ball joint, and one degree of freedom is reserved; the top of a shell is further provided with a soft rubber coating hood, the oscillating washing needle is further arranged in the soft rubber coating hood through a cylindrical joint to form a cylindrical pair, and four degrees of freedom are reserved; five degrees of freedom arereserved in total. The invention has the advantages that the track is self-adaptive, the machine does not stop after the needle head is blocked, and the track of the blocked needle head is changed ina self-adaptive mode; the safety of the needle head is ensured through the high degree of freedom of the ball joint and the cylindrical joint, the oscillating washing needle has five degrees of freedom through two connection constraints, and a high degree of freedom connecting structure is formed at the position of the flexible glue wrapping head cover. The motor torque is small, and the needle head cannot be jammed; the needle head cannot be broken, and safety is high; the threaded structure of the needle head facilitates smearing and throwing of medicine.

Description

technical field [0001] The invention relates to a cleaning needle and a high-degree-of-freedom connection structure and a cleaning method of a root canal cleaning device, belonging to the technical field of root canal treatment equipment. Background technique [0002] The oscillator for root canal treatment currently on the market is an ultrasonic oscillator, which specifically includes the following disadvantages: [0003] 1. The needle of the ultrasonic oscillator is a metal structure, and the machine will stop when the needle is blocked; [0004] 2. The connection structure of the needle head of the ultrasonic oscillator is fixed by the pin shaft, which has many constraints and low degree of freedom. The X and Y directions of the needle working plane have no degree of freedom; it is stuck and shut down after the inner wall of the root canal is blocked; [0005] 3. The needle of the ultrasonic oscillator is a metal structure, which is easy to break when it hits the inner ...

AI Technical Summary

Problems solved by technology

[0003] 1. The needle of the ultrasonic oscillator is a metal structure, and it will stop when the needle is blocked;

[0004] 2. The connection structure of the needle head of the ultrasonic oscillator is fixed by the pin shaft, which has many constraints and low degree of freedom. The X and Y directions of the needle working plane have no degree of freedom; it is stuck and shut down after the inner wall of the root canal is blocked;

[0005] 3. The needle of the ultrasonic oscillator is a metal structure, which is easy to break when it hits the inner wall of the root canal. Even if the operator is skilled, the movement of the patient's head will cause the needle to hit and cause the needle to break. For example, the patient coughs and causes the head to deviate Moreover, it is extremely difficult to remove the broken needle, which brings great inconvenience to patients and doctors, and even affects the treatment of patients, causing physical and mental harm, which is highly dangerous.

[0006] 4. Ultrasonic cleaning does not have the function of spraying and smearing medicine, which cannot solve the problem of spraying medicine. Changing needles or applying medicine by other means will result in long treatment time and cumbersome treatment procedures.
