Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to a kind of anti-stick head injection needle of endoscope-use.
Background technique
Endoscope-use injection needle is used in endoscopy to intravascular injection curing agent or tissue glue, to control Digestive
It unites the bleeding that has occurred or may occur, in injection needle used at present, metal cap is mounted on the front end of outer tube, and metal part is stretched
Outer tube out, to after the injecting glue of target position, portion of tissue glue can be sticked on metal cap, and injection needle leaves target after the completion of injection
When position, portion of tissue glue and tissue glue's overall separation on metal cap are sticked, to cause the portion of tissue glue of target position
Missing, influences haemostatic effect, injecting glue is caused to fail；In addition, the anteroposterior dimension of needle internal diameter used at present is identical, organizing
When glue is entered in injection needle by inner tube, since inner tube diameter is greater than needle internal diameter, tissue glue is direct by the cavity of major diameter
Cavity into minor diameter is very inconvenient.
Summary of the invention
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of anti-stick head injection needle of endoscope-use,
Gluing portion of tissue glue in metal cap front when can effectively prevent injecting glue；The liquid such as tissue glue are facilitated to flow into injection needle.
To solve the above problems, the technical solution adopted in the present invention is as follows:
A kind of anti-stick head injection needle of endoscope-use, it is characterised in that: including handle component and transfer unit, the handle portion
Part includes the front hand grip and back handle of hollow setting respectively, and the back handle front is mobilizable to be socketed in front hand grip rear portion,
The transfer unit includes outer tube and the inner tube set on outer tube, and the front hand grip is fixedly connected with outer tube and hollow portion phase
Logical, the back handle is fixedly connected with inner tube and hollow portion communicates, and said inner tube is fixedly connected with note far from one end of back handle
Needle is penetrated, for the outer tube far from metal cap is equipped with inside one end of front hand grip, front and back perforation is provided in the middle part of the metal cap goes out needle
Hole, the outer tube front end are provided with through hole corresponding with needle outlet.
Further, the back needle is fixed on inside inner tube front end, inside the injection needle and inner tube connecting pin
Edge is equipped with the first chamfering of truncated cone-shaped, and the point diameter of the first chamfering is identical as injection needle inside diameter.
Further, the outer tube material is PTFE, and the metal cap is fixedly connected with outer tube by hot melt molding technique.
Further, the needle outlet diameter is greater than injection needle outer diameter and is less than inner tube outside diameter.
Further, needle outlet rear portion is equipped with the second chamfering of truncated cone-shaped in the metal cap, and second chamfering front end is straight
Diameter is identical as needle outlet internal diameter.
Compared with prior art, the beneficial effects of the present invention are: the present invention in, by by metal cap pass through hot melt molding work
Skill is fixedly mounted on inside the front end of outer tube, can effectively prevent the tissue gluing injected when injection needle is injected
On metal cap, while outer tube is made of PTFE material, can also effectively prevent tissue glue's gluing on outer tube；By
Rear end is equipped with the first chamfering of truncated cone-shaped on the inside of injection needle, can be in injections such as injection needle injection of tissue glue, injection side
Being entered in the cavity of injection needle by inner tube cavity just.
