Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1, an ultra-fine fat particle suction tube comprises an extractor section 4, a non-porous wall section 3, a blunt end section 1 and a needle opening 2, wherein the length of the non-porous wall section 3 is L1, the length of the blunt end section 1 is L2, the cross section of the blunt end section perpendicular to the central axis of the non-porous wall section is an ellipse, and the opening is in the short side direction of the ellipse. The length of the imperforate wall section is L1, which is the straight line from the edge of the arc of the circle connecting the syringe section to the edge of the needle opening. The length of the blunted tip segment, which refers to the length from the edge of the needle mouth to the end of the needle, is L2. The middle of the injector receiving section 4 is provided with an inner hole which is communicated with a pipeline in the non-hole wall section 3 and is communicated with the needle opening 2.
The syringe receiving section 4 is connected with a syringe in a sealing way, and the syringe receiving section 4 is provided with threads 5.
The diameter of the outer face of the imperforate wall section 3 is between 1.2 mm and 2.0 mm.
A tiny needle opening 2 is arranged between the imperforate wall section 3 and the passivated tail end section 1, the diameter of the needle opening 2 is 1.0mm to 2.0mm, and the central axis of the needle opening 2 is perpendicular to the central axis of the needle tube of the imperforate wall section 3.
The blunt end section 1 is a closed flat blunt end which can be used for inserting into the skin and pushing open a blood vessel, the cross section of the needle tube is oval, and the side wall of the needle tube is provided with a needle opening 2 in the direction of the minor axis.
The length of the imperforate wall section 3 is L1, L1 > 20 mm.
The length of the passivation end section is L2, L2 < 5.0 mm.
The section 4 connected with the injector is mainly connected with the injector, and the section needs to be formed so as not to have burrs and other defects to avoid air leakage and insufficient pressure for extracting fat, and the outer wall of the section needs to be provided with a joint line and is subjected to integral demolding when a mold is designed. The diameter of this end is mainly to facilitate the manufacturing process, and is generally between 5 and 20 mm.
Preferably, the injector section 4 is 10 mm.
The blank wall section 3 is the transition between the injector section 4 and the blunting tip section 1, which is longer so that fat located relatively deep under the bridge of the nose can be injected.
Preferably, the diameter of the imperforate wall section 3 is 2.0 mm.
Preferably, the diameter of the small hole between the imperforate wall section 3 and the blunt end section 1 is 1.0 mm.
The blunt end 1 is an introduction section into the skin, which is as blunt as possible, so that the blood vessel can be pushed open. Since the blunting tip segment is closed, fat can only enter the nasal region from the orifice 2 near the blunting tip segment upon injection.
The needle tube is made of 201# or 304# stainless steel.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
