Description

A kind of clinical trocar of using

Technical field

This utility model belongs to a kind of medical apparatus and instruments, particularly a kind of trocar of emergent ventilation.

Background technology

In hospital, be used for the clinical trocar and be mostly to be used for the heeling-in pin, perhaps be used for reason, play therapy and acupuncture needle stripping bone therapy.Disclose a kind of " the medical trocar " as Chinese patent, it is by the trocar and can forming by reciprocating nook closing member in trocar chamber, and the front end of described nook closing member is a flat-top shape.The front end of the described trocar is the round blunt shape point, also can be needle pattern.Change the front end of trocar nook closing member into the flat-top shape, can be used as medical bushing type heeling-in pin and use, the medicine body that soon fully absorbs the drug is imbedded at affected area with the medicine body by the acupuncture point by the trocar, makes medicine directly act on affected area.Thereby its double effects with acupuncture point and Drug therapy has been opened up the comprehensive treatment that medicine is buried at a kind of new acupuncture point.But this trocar can not be done down emergent ventilation when doing the thyrocricoid puncture operation, stab trachea easily simultaneously, brings unnecessary side effect.

Summary of the invention

The purpose of this utility model is exactly at the existing trocar when thyrocricoid puncture is performed the operation, can not accomplish the emergent problem of ventilating and easily stabbing trachea, provide a kind of and both had puncture and be used to bury the function that treatments, bullet are pulled out, can accomplish emergent the ventilation again, be not easy to stab the effect of trachea.

The purpose of this utility model is achieved in that this clinically comprises nook closing member, sleeve pipe with the trocar, and described nook closing member comprises hollow syringe needle and the needle handle that is used to be connected syringe again, and described sleeve pipe is hard plastic cement pipe, and the front end slyness is enclosed within on the syringe needle.

During clinical use, will mould casing pipe sleeve firmly on nook closing member, and thrust ring first film and thrust in patient's trachea, after the position is suitable, nook closing member be extracted, will mould sleeve pipe firmly and stay in the trachea, with adhesive plaster hard plastic tube be fixed then; Blood sampling or toward interior injection if desired before not extracting nook closing member, is connected on syringe on the needle handle, draws blood or injects.

Owing to adopt said structure, the utlity model has simple in structurely, emergent ventilation when both can be used as thyrocricoid puncture can be used as blood sampling, injection, heeling-in pin again and uses, and simple in structure, function is many.
