Root canal operation working tip

Technical Field

The utility model relates to the technical field of root canal operation tips, in particular to a root canal operation tip.

Background

Bacteria and the like enter the root canal due to dental caries and the like, resulting in pulp lesions inside the root canal. For treatment of diseased teeth, it is necessary to first open the marrow (expose the root canal by drilling) and then perform the root canal treatment.

The number and location of the root canals on different teeth varies, and for this purpose, the doctor has to drill holes in the teeth at the possible locations of the root canal by means of the root canal surgical tip. The existing working tip (such as a cone) cannot quickly and efficiently find the position of a root canal orifice when drilling, correspondingly, more dentin can be removed, and the existing working tip can have a certain influence on the strength of teeth and the like, and even causes the situation that the teeth are cracked.

As shown in fig. 1 to 3, the root canal operation tip comprises a tip 1, wherein the tip 1 comprises a head 2, and the head 2 is in a truncated cone shape. The design has the advantages that: 1. for the surgical process of quickly and efficiently finding the root orifice position, the head 2 in the shape of the circular table can be used for quickly finding and confirming the root orifice position, and compared with the conical shape, the top surface in the shape of the circular table is circular, so that the grinding area is relatively large when grinding is carried out, the root orifice position can be quickly and efficiently found, and the grinding amount of dentin is reduced; 2. when the aperture is controlled, the head 2 is in a truncated cone shape, so that the head has a certain taper, and therefore, after confirming the position of the root orifice, the grinding depth is adjusted according to the size of the root orifice, thereby controlling the size of the aperture, and reducing the removal amount of dentin.

Optionally, in some embodiments, the needle tip 1 is composed of the head 2, the transition 3 and the tail 4; as shown in fig. 1, the cross-sectional area of the bottom surface of the head 2 is the largest; the transition part 3 is in a truncated cone shape or a cylindrical shape; the top surface and the bottom surface of the transition part 3 are respectively connected with the bottom surface of the head part 2 and the top surface of the tail part 4.

Alternatively, in some embodiments, the surface of the head portion 2 and/or the transition portion 3 and/or the tail portion 4 is provided with a sand layer, which may be a diamond sand layer, wherein the diamond sand may be attached to the surface of the head portion 2 and/or the transition portion 3 and/or the tail portion 4 by a sand plating process to form a diamond sand layer. The sand layer can strengthen the grinding ability, improves drilling efficiency, and in addition, the sand layer makes needle point 1 surface can become unsmooth, and the cooling water flow of being more convenient for wherein has improved the effect of cooling.

Alternatively, in some embodiments, the tail portion 4 is truncated cone-shaped, and the cross-sectional area of the tail portion 4 gradually decreases in a direction from the top surface to the bottom surface thereof.

Optionally, the head 2, the transition 3 and the tail 4 are of a unitary structure. Optionally, as shown in fig. 2-3, a needle bar 5 is further included, and the needle bar 5 is connected to the tail 4.

Optionally, the tail 4 and the needle bar 5 are of an integral structure.

Optionally, a neck 7 is further included, the neck 7 being connected to the needle shaft 5; an infusion channel 9 is arranged inside the neck 7. In this embodiment, the outer end of the infusion channel 9 is provided with a notch 6; meanwhile, the dental handpiece is further provided with a connecting part 8, a threaded hole 9 is further formed in the lower portion of the connecting part 8, and the connecting part 8 is connected with an output shaft of the dental handpiece through the threaded hole 9. The upper part of the connecting part 8 is connected with the neck part 7.

In the case of performing microscopic root canal treatment, grinding is performed at a position where a root canal is suspected to exist by using the truncated cone-shaped abrasive tip 1. Since the needle tip 1 has a truncated cone shape, the position of the root canal orifice can be quickly confirmed. After confirming the position of the root canal orifice, the sidewall of the head 2 rubs against dentin, except for dentin that overlies the root canal orifice, leaving the root canal orifice exposed and open. The round table-shaped needle point 1 can control the size of the opening, thereby ensuring the intensity of the tooth body to a certain extent, reducing the risk of postoperative complications (such as tooth body cracking) and improving the safety of the operation. The sanded needle tip 1 can enhance the grinding capability of the needle tip and improve the drilling efficiency. After sand plating, the surface of the needle point 1 becomes uneven, so that cooling water can flow into the needle point more conveniently, and the cooling effect is improved.
