Description
Technical field
This utility model relates to injection needle in a kind of larynx, and injection needle in specifically a kind of rustless steel larynx belongs to the medical needle field.
Background technology
Modern intralaryngeal surgery is the new technique that nearly half a lifetime is recorded and grown up; the new development of " voice surgery " is particularly arranged again in laryngosurgery after 80 years last century; meet larynx physiology, the little Minimally Invasive Surgery of damage under microscope or the laryngoscope; lay special stress on is under the magnification field condition in the art; protect voice completely removal lesion tissue the time better; for reducing post-surgical trauma tissue reaction, promote the early recovery vocal function for this reason, then need the part to inject medicinal liquids such as hormones.Before this utility model, the injection of children's's plastic cap sword-shaped needle is often used in this type of injection, because plastic flexible pipe is easily curved, need hold pincers under the arm again, operates very difficult.
Summary of the invention
The purpose of this utility model is to provide a kind of batch process simple in structure, easy, cost lower, safe in utilization, easy to operate, injection needle in the disposable rustless steel larynx.
This utility model in order to achieve the above object; injection needle in a kind of larynx is provided; constitute by the hollow needle tube (3) and the needle point (5) that are fixed on the needle stand (1); the outside that it is characterized in that hollow needle tube is with protecting tube (2); sealing ring (4) is arranged between protecting tube front end and hollow needle tube, and the front end of hollow needle tube is a needle point.
Injection needle in this utility model larynx, described needle stand (1) is the general entry needle needle stand of standard, the rear end of protecting tube (2) and hollow needle tube (3) all is fixed on the needle stand.Described hollow needle tube is elongated stainless steel tube, and length 150～230mm, external diameter 0.4～1.0mm, the front end of hollow needle tube then are the needle points (5) that bevel is removed the oval osculum of part back formation, and needle point is as medicine outlet.Described protecting tube one end is fixed on the needle stand, and protecting tube is shorter than hollow needle tube, be enclosed within hollow needle tube outer and and hollow needle tube between a sealing ring (4) is arranged, sealing ring is silver soldering or riveted sealing ring.The effect of protecting tube is fixing and protection elongated hollow needle tubing, makes it in use non-warping or fracture.Hollow needle tube is than protection pipe range 5～10mm, and the part band fine needle point that grows is the part of thrusting throat's tissue.
Injection needle has following advantage in this utility model larynx:
1, this utility model is simple in structure, and stainless steel material is made, and draws materials conveniently, produces in batches easily, and cost is lower, is suitable as injection needle in the disposable larynx.
2, use this utility model, solved the problem of the difficulty of deep part of throat administration for a long time, compare with other injection needle, has amplified in the visual field of medical personnel's operation, uses more convenient and quicker, has improved the safety of using, and welcome by medical personnel.
Description of drawings
Injection needle is described further with accompanying drawing in this utility model larynx:
Fig. 1 is an injecting head structure generalized section in this utility model larynx, and (1) is that needle stand, (2) are needle point for hollow needle tube, (4) for sealing ring, (5) for protecting tube, (3) among the figure.
