Abstract
The utility model relates to a puncture needle for a supersonic endoscope, which mainly comprises a front end needle head, a steel wire connected with the front end needle head and a needle tube matching with the front end needle head. The utility model is characterized in that the front end needle head is provided with a cutting end surface, and the cutting end surface is intersected with the steel wire and forms an acute angle included angle with the steel wire. When the utility model is used, the front end needle head of the puncture needle presents an arrow head shape and can quickly penetrate into organs of a focus position, because a living body introduction cavity is arranged between the front end needle head and the steel wire, a living body can be sucked in the living body introduction cavity, and then, an operating handle can be pulled. When the front end needle head enters the needle tube, the front end needle head and the steel wire form a cut, the living body is cut down and is collected in the needle tube, and an invalid result of biopsy taking can not happen. Because a gap between the steel wire and the needle tube is large, the bending and the deformation of the steel wire can not easily happen, the needle tube can be easily inserted, and the operation of the utility model is convenient.
Description
Technical field:
This utility model relates to the technical field of puncture needle, specifically a kind of puncture needle that is used for ultrasonic endoscope.
Background technology:
The development of modern technologies is attached to ultrasonic diagnosis in the scope, makes the doctor can utilize ultrasonic endoscope to diagnose out the more small and early stage focus of body cavities.But its correctness of the diagnosis of any image does not go up directly the pathology of tissue is chemically examined, therefore, after even ultrasonic endoscope enters human body, found to become the position of focus, the doctor still more wishes to utilize the advantage in the pincers road that scope has, obtain the biological tissue of lesions position, carry out pathological analysis.But can there be following problem in existing puncture needle: 1, the long diameter of a middle 1620mm is only less than the steel wire of 0.5mm, and when inserting the endoporus of same length, because steel wire diameter is very near the inwall of needle tubing, bending distortion easily is to such an extent as to can't insert; 2, the front end syringe needle is being extracted process wire, and after sucking biological tissue, because the syringe needle front end can't cut off biological tissue, therefore, when syringe needle was extracted from biological tissue, the tissue in the suction needle tubing differed and stays in the needle tubing surely, to such an extent as to get the invalid result of biopsy.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved puncture needle that is used for ultrasonic endoscope, and it can overcome gets the some shortcomings that biopsy is invalid, steel wire bends distortion easily in the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of puncture needle that is used for ultrasonic endoscope, it mainly comprises front end syringe needle, the steel wire that links to each other with the front end syringe needle, and the needle tubing that matches with the front end syringe needle, it is characterized in that: the front end syringe needle is provided with a cut end face, and this cutting end face and steel wire intersect and formation acute angle angle.
The front end syringe needle of puncture needle of the present utility model is arrow shaped during use, can thrust the organ of lesions position rapidly, introduce the chamber owing to be provided with a live body between front end syringe needle and the steel wire, can attract live body to enter this chamber, pull operation handle then, make the front end syringe needle when entering needle tubing, the two forms shearing, biological tissue is cut off, and in the income needle tubing, can not produced and get the invalid consequence of biopsy, because the gap of steel wire and needle tubing is bigger, steel wire also is not easy to take place the bending distortion, than being easier to insert needle tubing, has alleviated patient's misery to greatest extent.
Description of drawings:
Fig. 1 is the structural representation of this utility model one embodiment
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
This utility model mainly comprises front end syringe needle 1, the steel wire 2 that links to each other with the front end syringe needle, and the needle tubing 3 that matches with the front end syringe needle, its difference with the prior art is: the front end syringe needle is provided with a cut end face 4, this cutting end face and steel wire intersect and formation acute angle angle, the angle of this acute angle is the 30-75 degree, having formed one between cutting end face and the steel wire is the conical cavity in axle center with the steel wire, and when the front end syringe needle stretched into the position of getting live body, biological tissue just can be introduced into this conical cavity; The tip of front end syringe needle can be located at the center of front end, also can be located at any side of front end, and the spacing of needle tubing and steel wire is 0.1-0.3mm simultaneously.
In force, because the external diameter of steel wire and needle tubing aperture form matched in clearance, make steel wire after bending, doing slightly to repair still can easily turnover in needle tubing.Earlier whole puncture needle is thrust the organ of lesions position during use, promote operating grip again, the handle traction steel wire thrusts the position that need win live body, and the front end syringe needle of steel cord end just penetrates into the position of getting live body like this, and biological tissue just is drawn into the conical cavity of front end syringe needle, at this moment spur handle again, make the front end syringe needle when entering needle tubing, cutting end face and needle tubing interruption-forming are sheared, and biological tissue is cut off, and the income needle tubing, finish and get biopsy.
