Description

Root canal flushing needle with side opening

Technical Field

The utility model relates to the technical field of root canal flushing needles with side openings, in particular to a root canal flushing needle with a side opening.

Background

The root canal needs to be flushed by using the syringe combined with the needle in the root canal treatment of the stomatology, and the existing root canal flushing needle is generally made of metal materials, because the diameter of the tip is thicker, the needle is not easy to enter the middle and lower parts of the root canal, the flushing is not thorough, the cleaning of infection in the root canal is affected, and the needle has a tip inclined plane, so that the needle is easy to stab during operation, and even the transmission of infectious diseases can be caused.

Currently, the commonly used root canal flushing needles in clinic are mainly divided into two types: one is the bottom end opening, and another is the side opening syringe needle, uses the bottom end opening syringe needle, washes the below of all concentrated inflow syringe needles, and the effective distance that the flushing fluid like root point flowed is big, and is effectual to the clear away of root point infectious material, but very big to the pressure of root point, if wash the speed too high, the flushing fluid can directly overflow root point hole entering root point week tissue, causes root point week tissue's damage, postoperative reaction obvious, therefore the security of this kind of flushing syringe needle is relatively poor.

The needle head with the side opening has the advantages that the flushing fluid flows out from the side opening except for a small part in the needle head, and meanwhile, because the bottom end is closed, the flushing fluid is not easy to overflow under the pressure of the flushing fluid to the root tip, so that the damage to tissue around the root tip can be avoided, the safety is higher, but because the bottom end is closed, the inside of the needle head is divided into the flushing fluid, the needle head in the curved root canal cannot enter the root tip section, and the liquid replacement rate of the root tip section below the needle head is lower, so that the flushing effect is poor.

But the needle head root tip section with the bottom end opening commonly used at present has good flushing effect but poor safety, the needle head with the side opening has good safety, but has poor flushing effect on the root tip section, and the needle head made of metal is specially made at present, the tip section has certain rigidity and brittleness, and the tip section is provided with the side opening, so that the bending resistance of the side opening part is greatly reduced.
