Embodiment 1

[0021] like figure 1 , 5 , 6, including a gourd-shaped needle handle 1, a pintle 5 arranged at the tail of the needle handle 1 and communicating with the hollow needle body 2, a hollow needle body 2 connected with the needle handle 1, and a knife arranged at the end of the needle body 2 The head 3, the cutter head 3 is a bevel, and the plane where the arc-shaped edge is arranged on the top intersects with it, and the angle formed by the intersection line and the needle body is 90°.

Embodiment 2

[0023] like figure 2 , 5 , 6, the present invention includes a needle handle 1, a hollow needle body 2 connected to the needle handle 1, and a cutter head 3 arranged at the end of the hollow needle body 2. The cutter head 3 is an inclined plane, and the plane where the arc-shaped edge is arranged on the top intersects with it, and the angle formed by the intersection line and the needle body is 90°.

[0024] The needle handle 1 is a coil-shaped needle handle formed by winding filaments around the tail of the hollow needle body 2 .

[0025] The outside of the coil-shaped needle handle 1 is sheathed with a sleeve 6 which protects the needle head and the needle body, and a wedge-shaped block 7 is arranged between the sleeve 6 and the needle handle 1 .

Embodiment 3

[0027] like image 3 , 5 , 6, including a pintle-like needle handle 5 communicating with the needle body 2, a hollow needle body 2 connected to the pintle 5, a cutter head 3 arranged at the end of the needle body 2, the cutter head 3 is a bevel, and its The plane where the arc-shaped edge is arranged on the top intersects it, and the angle formed by the intersection line and the needle body is 90°. ——In fact, in this embodiment, the tip of the traditional syringe needle is cut in half laterally.

Abstract

The invention relates to the field of medical apparatuses, in particular to an arc-shaped-edge needle knife for medical treatment, face beautification and health care. The arc-shaped-edge needle knife comprises a needle handle, a hollow needle body which is connected with the needle handle, and a knife head which is arranged at the end part of the needle body. The knife head is an inclined surface and is intersected with a plane of a circular-arc-shaped edge which is arranged at the top end. An included angle between the intersection line and the needle body is within 30-150 degrees. Compared with the prior art, the arc-shaped-edge needle knife has the advantages that: 1) the functions of an injection needle and an interventional operation guide casing needle can be realized; 2) compared with the traditional needle knife with an in-line edge, tissues can be rapidly repaired more easily and are not apt to adhere and scar; 3) the maximum release effect can be achieved on the premise of minimum tissue invasion; and 4) due to the characteristic of the arc-shaped edge, the cross-shaped cutting, the Union-Jack-shaped cutting and the like of the traditional needle knife are thoroughly simplified to be in-line cutting, the tissue damages, the pains of patients and the treatment time of doctors are reduced, the operation is simple just like intramuscular injection, and a thorough needle knife revolution is aroused.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an arc-blade needle knife used for medical treatment, beauty treatment and health care. Background technique [0002] Existing small needle knives mainly consist of the following categories: 1. According to whether injection can be divided into traditional solid needle knives, hollow injection needle knives, etc.; .X), "Z" shaped flat needle knife (CN200820096239.3), arc-shaped needle knife (CN200710168517.1) connected by an arc between the knife head bar and the straight knife bar; three, according to the shape of the blade, it is divided into traditional The "one" character needle knife, the needle head is sunken in the opposite direction of injection, and forms a concave-edged injection needle with a circular arched blade (CN92208040.2), and the flat needle knife handle has an arc-shaped needle knife head. The concave surface of the arc-shaped needle knife head is a concave kni...
