Description

Root tip blood leading device

Technical Field

The utility model relates to a blood leading device, in particular to a root tip blood leading device which is used in root canal therapy operation and is especially suitable for 'dental pulp revascularization operation'.

Background

With the increasing enhancement of oral health and health care awareness and the continuous improvement of life quality, people gradually realize the importance of retaining natural teeth and simultaneously keep the idea of living pulp teeth to gradually enter the sight of people. "endodontic revascularization" is one of the important treatments for retaining viable pulp teeth.

The dental pulp revascularization, also called dental pulp revascularization, is a treatment method which uses sufficient root canal disinfection to make necrotic dental pulp tissue become a sterile matrix, then stimulates the bleeding of the apical root, and performs good coronal closure after artificially forming a blood clot in the root canal, wherein the blood clot contains stem cells, growth factors, platelet fibrin and the like, and artificially forms a scaffold to promote the formation of new dental pulp-like tissue in the root canal and the continued development of the root of a tooth.

In "endodontic revascularization", there is no special tool for the step of stimulating bleeding, and a 40 # K file for root canal treatment is generally used as a puncture tool. The doctor holds the K file by hand, punctures the apical foramen after entering the root canal, and the wound waiting for the puncture slowly bleeds and is full of the root canal, forms the blood clot. The disadvantages are as follows: the K file is a tool for root canal treatment, and is usually used after being connected with a power handle, and in the operation process of the 'endodontic revascularization operation', a doctor needs to hold the K file to operate, so that the space in the oral cavity is small and is not suitable for operation; 2. the K file for puncture is also disinfected independently, so that the sterility is ensured, and the cost of manpower and material resources is increased; 3. because of no professional tool, the prior art only punctures the root tip to wait for the blood to flow out, sometimes, the puncture is unsuccessful once and needs secondary puncture, the active blood drainage can not be realized, the puncture needs to wait for the blood to automatically overflow the root canal after the root canal orifice, the effect is not ideal, and the operation efficiency is low; 4, the k file is sharp tool, has no any protection device, and has the risk of needle stick injury in the use, arrangement and treatment processes.

In combination with the above, the lack of special instruments for endodontic revascularization is reflected.
