Abstract

The utility model relates to a bushing type puncture needle for diagnosis and treatment of medical treatment. The utility model comprises an empty needle, a needle core, a hollow guiding tube and a metal guiding wire. The needle core is longer that the empty needle. The tip point adjacent to the needle core is provided with a saw tooth groove. The needle core and the hollow guiding tube can be inserted in the empty needle, and the metal guiding wire can be inserted in the hollow guiding tube. The needle core is inserted in the empty needle when the utility model is used, percutaneous puncture is performed, biopsy is extracted by using the saw tooth groove of the tip of the needle core, and puncture and biopsy extraction are caused to be successful one time. The hollow guiding tube in which the metal guiding wire is inserted is arranged in the empty needle. The position of the hollow guiding tube can be accurately determined because density of the metal guiding wire is high, and development is clear. The empty needle and the metal guiding wire are pulled out, and the hollow guiding tube is left in a body for a long time. Medicine injection, drainage and treatment can be performed at any time. The utility model has the advantages of reasonable structure, simple use, high safety and alleviatory pain of patients. The utility model can be widely suitable for diagnosing and treating diseases of multiple systems and multiple organs of human bodies.

Description

A kind of multi-functional conduit placement in the treatment device

This utility model relates to the extension-type puncture needle of diagnosis in a kind of medical treatment, treatment usefulness.

Chinese patent CN2228767Y has announced a kind of multi-functional puncture needle, it comprises needle body, nook closing member and flexible pipe, utilize needle body, nook closing member to puncture and extract biopsy, utilize flexible pipe to carry out injection, drain, treatment, but because the relation of flexible pipe density, be difficult in vivo developing, be difficult to accurately determine its position.

The purpose of this utility model is to provide a kind of and both can have disposablely finished puncture and extract biopsy, can carry out injection, drain, treatment for a long time again, also can accurately determine the multi-functional conduit placement in the treatment device of catheter position by developing.

This utility model is achieved in that it comprises empty needle, nook closing member, hollow tubing conductor, wire guide, and nook closing member is longer than empty needle, locates that near the tip of nook closing member serrated slot is arranged, and nook closing member, hollow tubing conductor can insert in the empty needle, and wire guide can insert in the hollow tubing conductor.

Advantage of the present utility model is to utilize the serrated slot at nook closing member tip, after nook closing member insertion empty needle carries out percutaneous puncture, directly extracts biopsy, makes puncture, extracts once success of biopsy; The hollow tubing conductor that is inserted with wire guide is inserted in the empty needle, because wire guide density height, it is clear to develop, thereby can accurately determine the position of hollow tubing conductor; Extract empty needle and wire guide out, hollow tubing conductor is kept somewhere in the body for a long time, can carry out injection, drain, treatment at any time, it is rational in infrastructure, uses simple, safe and reliable, alleviate patient's misery greatly, can be widely used in the diagnosis and the treatment of human body multisystem, many organ diseases.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the sketch map that nook closing member inserts empty needle;

Fig. 2 is the sketch map that is inserted with the hollow tubing conductor insertion empty needle of wire guide;

Fig. 3 is the sketch map of hollow tubing conductor;

Fig. 4 is the sketch map of wire guide.

As shown in drawings, present embodiment comprises empty needle 1, nook closing member 2, hollow tubing conductor 3, wire guide 4, and nook closing member 2, hollow tubing conductor 3 can insert in the empty needle 1, and wire guide 4 can insert in the hollow tubing conductor 3.Nook closing member 2 is longer than empty needle 1, there is serrated slot 5 at place, tip near nook closing member 2, and needle handle 6 ends of close nook closing member 2 have a spring 7, and the length of spring 7 meets the following conditions: after nook closing member 2 inserts empty needles 1, when not being stressed, the serrated slot 5 at nook closing member 2 tips places in the empty needle 1 (Fig. 1) just.Scale (Fig. 3) is arranged on the hollow tubing conductor 3.

During use, nook closing member 2 is inserted in the empty needle 1, after percutaneous punctures, with the needle handle 6 of hand nook closing member 2, with compression spring 7, serrated slot 5 is exposed to outside the empty needle 1, unclamp needle handle 6 after extracting biopsy, because the tension force effect of spring 7 is inserted in the empty needle 1 serrated slot 5 that has biopsy again, extract nook closing member 2 out, disposable finishing punctured and the extraction biopsy.The hollow tubing conductor 3 that is inserted with wire guide 4 is inserted in the empty needle 1, because wire guide 4 density height, it is clear to develop, thereby can accurately determine the position of hollow tubing conductor 3, and can be according to the scale on the hollow tubing conductor 3, determine that hollow tubing conductor 3 enters the degree of depth of human body, so that realize the effect of hollow tubing conductor 3 better.Extract empty needle 1 and wire guide 4 out,, can carry out injection, drain, treatment at any time 3 long-time the indwellings in the body of hollow tubing conductor.

Claims
