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, the needle specially used for autologous fat injection through oral cavity puncture needle insertion comprises a syringe receiving section 1, a first section 2, a second section 3, a third section 4, a blunt end section 5, a needle opening 6, a first circular arc section 8 and a second circular arc section 7, wherein the first section is L1 in length, the second section is L2 in length, the third section is L3 in length, the distance between the first section and the third section is L4, the whole needle is roughly in a zigzag shape, the first section 2, the second section 3 and the third section 4 are straight line sections, two adjacent sections are in circular arc transition, and the first section 2 and the third section 4 are respectively arranged on two sides of the second section 3 and are not arranged on the same side. An inner hole is arranged in the middle of the syringe connecting section 1, and the inner hole is communicated with the pipelines in the first section 2, the second section 3, the third section 4, the first circular arc section 8 and the second circular arc section 7 and communicated with the needle opening 6.
Preferably, the blunting end section 5 is provided with a needle opening, the needle opening is formed by cutting the needle tube along the normal direction of a plane formed by the first section 2 and the second section 3 through an arc, the arc has an axis, the central axis of the needle opening 6 is perpendicular to the central axes of the first section, the second section and the third section, and the needle opening faces the direction of the first section.
The syringe receiving section 1 is provided with threads for connection with a syringe.
The central axes of the first section 2, the second section 3 and the third section 4 are all in one plane but not on one straight line. Because the inside of the oral cavity is inconvenient for puncture operation, the needle needs to be bent once, so the needle is bent into three sections, the length of each section is approximately equal, and the total length of the three sections is about 70 mm. Because the needle is only bent once, the three sections of the tubes are in the same plane but not in the same straight line, so that the needle is convenient to package and transport.
The length of the first section 2 is L1, and L1 is more than 10.0mm and less than 50.0 mm.
The blunt tip section 5 is a blunt tip with a side opening that can be used for insertion into the skin.
The length of the second section 3 is L2, and L2 is more than 10.0mm and less than 50.0 mm.
The length of the third section 4 is L3, and L3 is more than 10.0mm and less than 50.0 mm.
The length of the passivating end segment 5 is less than 5.0 mm.
Preferably, the distance between the first section and the third section is L4, and 10.0mm < L4 < 30.0 mm.
The central axes of the first section 2 and the third section 4 are parallel, and the first section 2, the second section 3 and the third section 4 are straight sections and are in circular arc transition.
The section 1 for connecting the injector is mainly connected with the injector, the section needs to be formed so as to avoid defects such as burrs and the like, so that the injection pressure is insufficient, the outer wall of the section needs to be designed so as to have no parting line, and the outer wall needs to be integrally demoulded. The diameter of this end is mainly to facilitate the manufacturing process, and is generally between 5 and 20 mm.
Preferably, the length of the injector section 1 is 10 mm.
Preferably, the diameters of the outer pipe walls of the first section 2, the second section 3 and the third section 4 are equal, and the diameters are 2.0 mm.
The blunt end section 5 is an introduction section into the skin, which is blunt to avoid damaging the blood vessels.
The extraction pipe is made of 201# or 304# stainless steel.
The injection needle has the advantages of no mark on the surface after operation, closer needle insertion point to ligament, small injury and quick recovery.
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.
