Abstract

An endosocopic catheterization puncture needle comprises a needle body, a needle tip and a needle handle, wherein the needle tip and the needle handle are arranged on the two ends of the needle body, a needle sheath and a needle sheath handle sleeve the needle body, the needle sheath handle is arranged on the tail portion of the needle sheath and is adjacent to the needle handle, the needle body and the needle handle are of a hollow structure, the needle sheath is installed on the needle body in a sealing manner, and a side hole is arranged in the outer sidewall of the needle sheath at the front end of the needle body. The puncture needle can be pulled out after puncture, and a vascular retain tube retains in a blood vessel, thereby preventing danger caused by the sharp needle tip ripping off a vascular wall. The endosocopic catheterization puncture needle is safe to use.

Description

Vascular catheterization puncture needle under scope

(1) technical field

The present invention relates to vascular catheterization puncture needle under a kind of scope.

(2) background technology

Injection medicine, measurement pressure and Hemodynamics Study, blood component analyzing etc. in visceral vessel in visceral vessel Diagnosis and treatment to disease play very important effect.Currently mainly by having punctured under scope, due to puncture needle Needle point is the sharpest, adds the involuntary movements such as heart beating, breathing and digestive tract, is therefore particularly easy to cause puncture needle needle point to wear To blood vessel wall or scratch blood vessel and cause massive hemorrhage and life-threatening complication.This type of work is seldom carried out at present in clinical position Making, thus test can only complete in animals.Native system can solve the problems referred to above.

(3) summary of the invention

The technical problem to be solved in the present invention is to provide vascular catheterization puncture needle under a kind of scope, and processing safety is high, makes With effective.

To this end, the present invention takes techniques below scheme:

Vascular catheterization puncture needle under a kind of scope, includes needle body, needle point and needle handle, and described needle point and needle handle are arranged in pin Body two ends, described needle body is set with stylophore and stylophore handle, and stylophore handle is arranged on stylophore afterbody, and adjacent needle handle is arranged, described pin Body and needle handle are hollow structure, and described stylophore is sealingly mounted on needle body, and described needle body front end is positioned on the sidewall outside stylophore Have side opening.

The needle point of described needle body is wedge.

Described side opening is two, adjacently positioned.

The work process of the present invention is: choose point of puncture under scope, and described puncture needle is thrust blood vessel, when needle body side opening There is blood to flow out, illustrate that puncture needle the most successfully thrusts blood vessel, at this moment extract handle, by puncture seal wire along needle handle and needle body Cavity is inserted to Endovascular certain depth and fixes, and exits puncture needle；Then blood vessel indwelling tube is inserted blood vessel along puncture seal wire In, exit puncture seal wire, fixing blood vessel indwelling tube, complete vascular catheterization art under scope.

The invention have the advantage that 1, punctured and can extract puncture needle, use blood vessel indwelling tube indwelling in the blood vessel, it is to avoid Sharp-pointed needle point scratches the various harm that blood vessel wall causes, and uses safer；2, medicine, collection are injected by blood vessel indwelling tube Blood sample or pressure measurement and Hemodynamics Study, more accurately, safe and reliable.

Fig. 1 is present configuration schematic diagram；

Fig. 2 is the top view of Fig. 1.

(5) specific embodiment

Referring to the drawings 1,2, vascular catheterization puncture needle under a kind of scope, include needle body 1, needle point 2 and needle handle 3, described pin Point and needle handle are arranged in needle body two ends, and described needle body is set with stylophore 4 and stylophore handle 5, and stylophore handle is arranged on stylophore afterbody, phase Adjacent needle handle is arranged, described needle body and needle handle are hollow structure, and described stylophore is sealingly mounted on needle body, and described needle body front end is positioned at Side opening 6 is had on sidewall outside stylophore.The needle point of described needle body is wedge.Described side opening is two, adjacently positioned.
