Description

Technical Field

[0001] The utility model relates to the technical field of dental medical instruments, in particular to a V-shaped sonic root canal washer. Background Art

[0002] The current dental cleaning methods are as follows: 1. Energy is transmitted through traditional mechanical vibrations, and the rigid working end is used to clean the root canal of the tooth. 2. Ultrasonic vibrations are generated by tooth cleaning instruments or special instruments, and the rigid working end is used to clean the root canal of the tooth.

[0003] The method mentioned in method 1 has the following problems: the energy transmission by the mechanical vibration method is weak. For example, when the working end is lengthened, the energy at the end is insufficient and a thorough cleaning effect cannot be achieved.

[0004] In the method mentioned in method 2, the use of tooth cleaning instruments or special instruments to generate ultrasonic vibrations is too expensive, so that clinical dentists cannot configure it, resulting in the omission of this necessary and meaningful step during clinical operation, which in turn reduces the success rate of root canal treatment or even leads to the failure of root canal treatment.

[0005] A serious problem that exists in both method 1 and method 2 is that both use a rigid working end to act on the tooth body. When the working end and the root canal of the tooth body are stuck in the deep apical area, the needle is easily broken (the instrument is separated), resulting in treatment failure and medical accidents. The rigid working end has a certain service life, and the service life is very short, resulting in high cost of use. Utility Model Content

[0006] The main purpose of the utility model is to provide a V-shaped sonic root canal cleaning instrument so as to effectively solve the problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a V-shaped ultrasonic root canal washing instrument, comprising an electric toothbrush body, a vibration shaft, a connecting rod, a long threaded cap, and a gutta-percha tip; the electric toothbrush body refers to the assembly of the electric toothbrush without the toothbrush head, an external thread is arranged on the vibration shaft of the electric toothbrush, one end of the L-shaped connecting rod is provided with a threaded hole which is threadedly connected to the vibration shaft of the electric toothbrush, the head of the other end of the connecting rod is a round head, a section of external thread is arranged behind the round head, and a circular boss is arranged behind the external thread, the long threaded cap is a hollow round tube with a tapered hollow head at the front end and an internal thread at the rear end, a circular hole is opened at the front end, the gutta-percha tip is needle-shaped, the front end is thin and the rear end is thick, the rear end is round-headed, and is inserted in the long threaded cap, the pointed head is on the outside of the long threaded cap, and the rear end is inside the long threaded cap, the long threaded cap is threadedly connected to the connecting rod, and a control circuit board is arranged inside the electric toothbrush body.

[0008] Preferably, after assembly is completed, the round head of the connecting rod presses the tail of the gutta-percha tip tightly, so that the tail of the gutta-percha tip and the inner cavity of the long threaded cap remain in a fixed state.

[0009] Preferably, the electric toothbrush body adopts a magnetic levitation high-frequency vibration motor, and the motor vibration frequency is about 31,000 times / minute.

[0010] Preferably, the electric toothbrush body is provided with a high and a low switch.

[0011] Preferably, the connection between the connecting rod and the vibration shaft can be fixed by welding.

[0012] Preferably, the electric toothbrush body can be replaced with the Xiaomi electric toothbrush T200 body.

[0013] Preferably, the electric toothbrush body adopts a rechargeable battery and is provided with a charging socket.

[0014] The gutta-percha tip used in the utility model is a gutta-percha tip product used in root canal treatment. The gutta-percha tip is in a semi-soft state, which can transmit ultrasonic energy and avoid the problem of needle breakage, thereby preventing medical accidents during root canal preparation. During the treatment process, the gutta-percha tip is in a V-shaped vibration state, which can transmit energy in a small range, and efficiently, quickly and safely remove the debris and bacterial contaminants generated by root canal preparation (a necessary step in the oral root canal treatment process), thereby greatly improving the success rate of root canal treatment.

[0015] The beneficial effects of the utility model are: low cost, no accident risk, fast cleaning speed and good effect. BRIEF DESCRIPTION OF THE DRAWINGS
