Description
Technical Field
The utility model relates to the technical field of medical treatment, particularly, be a tooth auxiliary device that opens marrow.
Background
Endodontic and periapical diseases are one of the most common infectious diseases of dental pulp, and root canal therapy is an effective treatment method thereof. Endodontics is the removal of infection by mechanical and chemical preparation and the tight occlusion of the root canal cavity by gutta percha. Good opening and preparation of the medullary canal approach are the initial and important steps in root canal treatment. The marrow opening is to enter the pulp chamber through the crown zygosity and establish a proper root canal approach for root canal preparation, and the complete de-pulp chamber top lays the foundation for the subsequent root canal preparation and is also the key technology for the success of the root canal treatment.
At present, when the marrow opening is carried out on teeth clinically, the nine-square grid is drawn by a pencil on the combined surface of the complete teeth manually, and then the marrow opening is carried out on the central grid of the nine-square grid, so that for some doctors with the first time or lack of experience, the situations of overlarge opening of the marrow, large deviation and the like easily occur when the marrow opening is directly carried out, and the damage to normal tooth tissues is large.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems in the prior art, for example, the utility model discloses a tooth marrow opening auxiliary device, which comprises: the fixing ring, the supporting tube, the connecting tube, the fixing rod, the fixing hole, the fixing plate and the medullary opening hole;
the fixing ring is provided with a supporting tube, the supporting tube is provided with a connecting tube, a plurality of fixing rods are arranged on the top of the connecting tube in a crossed mode to form a plurality of fixing holes, the fixing plates are arranged in the fixing holes and located at the center of the supporting tube, and the center of each fixing plate is provided with a medullary opening hole.
Preferably, the number of the fixing holes is equal to or greater than nine.
Preferably, a plurality of the fixing rods are crossed to form a squared figure structure.
Preferably, the fixing rods, the connecting pipes and the fixing plates are of an integrally formed structure.
The utility model provides a tooth auxiliary device that opens marrow possesses following beneficial effect: through with this device suit on the tooth, the dead lever forms nine palace check structures on the connecting pipe, is provided with the circular shape in nine palace check center square and opens the marrow hole, and the doctor passes through, opens the marrow operation location through opening the marrow hole, avoids appearing opening the marrow hole mouth too big, the great scheduling problem of deviation, improves and opens marrow speed and accuracy, reduces the risk of excessively removing healthy tooth body tissue.
