The utility model belongs to the field of medical minimally invasive surgical instruments, and particularly relates to a disposable flushing needle which comprises a handle, a needle tube seat and a needle body, wherein the needle tube seat is arranged on the handle, the needle body is fixedly connected to the needle tube seat, a cutter section is arranged at the end part of the needle body, a liquid outlet is arranged at the part, close to the cutter section, of the needle body, and the orientation of the liquid outlet is consistent with the direction of a cutting edge of the cutter section. Compared with a tubular knife formed by edging the front end of the tube in the past, the needle tube is provided with the independent cutting knife section which forms a structure similar to a scalpel, so that the cutting effect is greatly improved, soft tissues are easier to strip, the damage to an affected part is reduced, meanwhile, the liquid outlet hole is formed in one side of the cutting edge, liquid medicine can be injected to a focus directly, the liquid medicine is easier to absorb, the effect is better, after the cutting edge of the cutting edge is loosely stripped, the liquid medicine is injected from the liquid outlet in the direction consistent with the direction of the cutting edge, and the injection part is just the side after tissues are loosened, so the injection effect is better.

Description

Disposable flushing needle

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a disposable flushing needle.

Background

The disposable washing needle is used for loosening and stripping soft tissue adhesion or aseptic inflammation parts by using a special washing needle tool, so that the clamping pressure of local blood vessels and nerves is relieved, the microcirculation of lesion parts is improved, and the balance of the internal force of local tissues is restored. Generally, the most effective medicine is selected to be injected into a focus, and the most effective medicine is absorbed by capillary vessels of local tissues to improve circulation, inhibit peripheral nerves and block centripetal pain conduction, so that the vicious circle of pain-muscular tension or small vessel smooth muscle spasm-pain aggravation is blocked, and the pain is quickly relieved. The process of 'inflammatory exudation-adhesion-scar formation' can also be inhibited through the action of medicaments, so that the stimulation of inflammatory substances to the body is eliminated and the relapse is reduced while the local nerve and blood vessel clamping pressure is relieved and the local dynamic and static balance is adjusted.

The existing flushing needle is generally provided with a cutting edge at the end part of a needle tube, the cutting has large damage to an affected part, and the liquid medicine injected when a liquid outlet is arranged at the lower part can be dispersed to the periphery because the needle tube is flat, so that the administration effect is poor.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems, the utility model aims to provide a disposable flushing needle which has good cutting effect and little damage to the affected part and is more beneficial to the liquid medicine to reach the focus.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: the utility model provides a disposable washing needle, includes handle, needle tube seat and needle body, the needle tube seat dress is on the handle, needle body fixed connection be in on the needle tube seat, the tip of needle body is equipped with the cutter section, being close to of needle body cutter section department is equipped with the liquid outlet, the orientation of liquid outlet with the cutting edge blade direction of cutter section is unanimous.

In the technical scheme, the handle is in a gourd shape.

In the technical scheme, the length of the cutting edge of the cutting knife section is 3-5 mm.

In the above technical scheme, the length of the liquid outlet from the cutting edge is 1-2 mm.

In the above technical solution, the cutting blade section is a curved blade, and the arc angle of the blade is 110-120 °.

In the technical scheme, the length of the needle body is 35-40 mm.

In the above technical scheme, the cutter segment is a flat cutter structure, and the cutting edge is located at the side of the cutter segment.

In summary, compared with the conventional technical means, the technical scheme of the utility model has the following beneficial effects: compared with the prior tubular knife formed by edging the front end of the tube, the independent cutting knife section forms a structure similar to a scalpel, the cutting effect is greatly improved, soft tissues are easier to peel, the damage to an affected part is reduced, meanwhile, the liquid outlet hole is formed in one side of the cutting edge, the injected liquid medicine can directly reach a focus and is easier to absorb, the effect is better, in the prior art, the liquid medicine is dispersed to the periphery because the liquid outlet is arranged at the lower part, and after the cutting edge of the cutting edge is loosened and peeled, the liquid medicine is injected from the liquid outlet in the direction consistent with the cutting edge of the cutting edge section, the injection part is just on the side after the tissues are loosened, so the injection effect is better, the blood and impurities on the surfaces of oral cavity, ophthalmology, skin and the inside of tissues can be effectively cleaned, and the clinical oral cavity, the surgical operation is more convenient, and the operation is more convenient Cleaning of the eye, skin surface and tissue interior works well.
