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, a molding injection needle for injecting and filling through the nasal tip of the oral cavity comprises an injector connecting section 1, a first section 2, a second section 3, a third section 4, a blunt end section 5, a first circular arc section 7, a second circular arc section 8 and a needle opening 6, wherein the length of the first section 2 is L1, the length of the second section 3 is L2, the length of the third section 4 is L3, the first section 2, the second section 3 and the third section 4 are straight sections, adjacent two sections are in circular arc transition, the first section 2 and the third section 4 are arranged on the same side of the second section 3, an included angle ∠ A between the first section and the second section is larger than 90 degrees, and an included angle ∠ B between the third section and the second section is larger than 90 degrees, namely 180 degrees0>∠A>900、1800>∠B>900The entire needle is substantially in the shape of a fish hook. 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 7 and the second circular arc section 8 and communicated with the needle opening 6.
The syringe receiving section 1 is provided with a thread, which is designed to be connected to 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 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 by using an arc, the arc has an axis, the axis is a needle opening axis, and the needle opening axis is vertical to the central axes of the first section 2 and the second section 3.
The length of the first section 2 is L1, and L1 is more than 10.0mm and less than 50.0 mm.
The end of the blunted end section 5 is provided with a needle opening 6, the central axis of the needle opening 6 is perpendicular to the central axes of the first section 2, the second section 3 and the third section 4, and the needle opening 6 faces the direction of the first section 2.
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 first section 2, the second section 3 and the third section 4 are straight-line sections, and adjacent two sections 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 extraction pipe 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.
