Abstract

An endosocopic catheterization system comprises a puncture needle which 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 endosocopic catheterization system further comprises a guide wire and a vascular retain tube, wherein the guide wire has length marks, a through hole is arranged in the side surface of the vascular retain tube, and the front end of the vascular retain tube has length marks. The puncture needle can be pulled out after puncture, and the 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 system is safe to use.

Description

Vascular catheterization system under scope

(1) technical field

The present invention relates to vascular catheterization system 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 system under a kind of scope, and processing safety is high, uses Effective.

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

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

Also including puncture seal wire and blood vessel indwelling tube, described seal wire is provided with length mark；Described blood vessel indwelling tube Side is provided with through hole, and there is length mark front end.

The needle point of described needle body is wedge.

The side opening of described needle body front end is two, adjacently positioned.

Multiple through hole is had on described blood vessel indwelling tube.

The work process of the present invention is: one, choose point of puncture under scope, and described puncture needle is thrust blood vessel；Two, pin is worked as Hole, side has blood to flow out, and illustrates that puncture needle the most successfully thrusts blood vessel；Three, handle is at this moment extracted, by puncture seal wire along pin The cavity of handle and needle body is inserted to Endovascular certain depth and fixes；Four, puncture needle is exited；Five, by blood vessel indwelling tube along puncturing use Seal wire inserts Ink vessel transfusing；Six, puncture seal wire is exited, fixing blood vessel indwelling tube, complete vascular catheterization art under scope, such as accompanying drawing 4 Shown in.

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；3, puncture seal wire front end is relatively soft is difficult to Damaging blood vessel wall, postmedian has certain degree of hardness convenient to operate；Length mark on seal wire is easy to concrete operations；4, described blood vessel stays Put and on pipe, have multiple through hole, improve data accuracy；When this indwelling tube side is attached to blood vessel wall, and through hole remains to keep clear； 5, described seal wire and blood vessel indwelling tube are arranged above with length mark, it is seen that one or a group echo are it may determine that seal wire or blood vessel Indwelling tube insert blood vessel the degree of depth, this point is extremely important, because the visual field is the openst in narrow and small body cavity, often cannot sentence Disconnected seal wire or indwelling tube insert the degree of depth of blood vessel, it is easy to cause seal wire or indwelling tube skids off the danger causing massive hemorrhage, sees Just can judge the degree of depth of insertion blood vessel to a group or a length mark, to operation is very easy, it is to avoid blood vessel indwelling tube or The danger that seal wire skids off, improves safety.

(5) specific embodiment

1-5 referring to the drawings, vascular catheterization system under a kind of scope, include puncture needle, described puncture needle includes and includes Having needle body 1, needle point 2 and needle handle 3, described needle point and needle handle are arranged in needle body two ends, and described needle body is set with stylophore 4 and stylophore Handle 5, stylophore handle is arranged on stylophore afterbody, and adjacent needle handle is arranged, described needle body and needle handle are hollow structure, and described stylophore seals peace Being contained on needle body, described needle body front end is positioned on the sidewall outside stylophore and has side opening 6；Also include puncture seal wire 7 and blood Pipe indwelling tube 9, described seal wire is provided with length mark 8；Described blood vessel indwelling tube side is provided with through hole 10, and there is length mark front end 11.The needle point of described needle body is wedge.The side opening of described needle body front end is two, adjacently positioned.Open on described blood vessel indwelling tube There is multiple through hole.
