Abstract

The utility model relates to a diagnosing and treating machine in medical care, comprising a needle body, a needle core and a soft tube. The utility model is characterized in that biopsy is direct extracted after the needle core is inserted in the needle body for carrying out puncture by making use of a saw tooth groove on the back of the tip part of the needle core; thus the puncture and the biopsy extraction can be successfully achieved once; thus the soft tube can be retained in a human body for a long time for carrying out repeated gas and liquid pumping and medicine injecting treatment or carrying out sustained closed type drainage. The utility model has the advantages of reasonable structure, convenient operation, small damaging area and the pain of patients relieving. The utility model is widely used for the diagnosis and the treatment of every hollow viscera of the human body such as thoracic cavity, abdominal cavity, etc.

Description

A kind of multi-functional puncture needle

This utility model relates to diagnosis, the therapeutic device in a kind of medical treatment, particularly a kind ofly integrates puncture, proposes biopsy, bleeds, the multi-functional puncture needle of drawing liquid, drain, injection.

Chinese patent CN2030089Y has announced a kind of helical edges biopsy needle, it comprises sleeve pipe, core pin and spiral needle, its operation principle punctures in the sleeve pipe for earlier the core pin being inserted, extract the core pin then out, spiral needle is revolved people's sleeve pipe, make its rotation, extract biopsy by helical edges, puncture and extraction biopsy need be carried out for twice.If patient need bleed, drawing liquid, drain, injection,, carry out said process in the human body so can only temporarily it be stayed, and can't continue, carry out repeatedly because of sleeve pipe is made by hard material.

The purpose of this utility model is to provide a kind of puncture, extracts once success of biopsy, and have for a long time bleed repeatedly, multi-functional puncture needle that drawing liquid, drain, injection etc. act on.

This utility model is achieved in that this utility model comprises needle body, nook closing member and flexible pipe, and nook closing member is longer than needle body, and there is a serrated slot at its most advanced and sophisticated back, and hose outside diameter conforms to needle body internal diameter size, and length is longer than needle body.

Advantage of the present utility model is to utilize the serrated slot at the most advanced and sophisticated back of nook closing member, after nook closing member insertion needle body punctures, directly extract biopsy, make puncture, extract once success of biopsy, and flexible pipe can be put for a long time and be stayed in the human body, bleed repeatedly, drawing liquid, drug-injection in treatment, or do to continue closed drain.It is rational in infrastructure, and is easy to operate, and damage surface is little, alleviates patient's misery greatly, can be widely used in the diagnosis and the treatment of each hollow organs of human body such as thoracic cavity, abdominal cavity.

Below in conjunction with drawings and Examples this utility model is described in further detail:

Structural representation when Fig. 1 is this utility model puncture;

Outside drawing when Fig. 2 is this utility model extraction biopsy;

Fig. 3 is the sketch map of this utility model flexible pipe part.

This utility model comprises needle body 1, nook closing member 2 and flexible pipe 3, and there is a serrated slot 4 at nook closing member 2 most advanced and sophisticated backs, and end has handle 5, and nook closing member 2 is longer than needle body 1, and flexible pipe 3 external diameters conform to needle body 1 internal diameter size, and length is longer than needle body 1.

During use, nook closing member 2 is inserted in the needle body 1, both are most advanced and sophisticated to overlap, and punctures, and then nook closing member 2 is further inserted in the living tissue, and rotary handle 5 exposes serrated slot 4, extracts nook closing member 2 afterwards, and it is external to utilize sawtooth that living tissue is pulled out, to extract biopsy.As needs bleed, drawing liquid, drain, injection, then flexible pipe 3 is inserted in the needle body 1, needle body 1 is extracted out along flexible pipe 3, flexible pipe 3 is put is stayed in the chamber, can bleed repeatedly, drawing liquid, injection, and can do to continue closed drain.After finishing, flexible pipe is stayed for a long time in body, can repeatedly use, change repeatable operation, alleviated patient's misery for once carrying out.

Claims

1, a kind of multi-functional puncture needle comprises needle body, nook closing member, and nook closing member is longer than needle body, it is characterized in that it comprises that also an external diameter conforms to needle body internal diameter size, and length is longer than the flexible pipe of needle body, and there is a serrated slot at the most advanced and sophisticated back of nook closing member.
