Abstract

The invention discloses a puncture biopsy guide device. The puncture biopsy guide device comprises a guide device body (1) and a fixing device (4), a puncture biopsy needle installing hole (2) is formed in the guide device body (1), and the fixing device (4) is connected with the guide device (1). The puncture biopsy guide device has the advantages that a user can wear the guide device on the finger, guide the guide device to the point position needing puncture by means of touch sensation and penetrate a puncture biopsy needle through the guide device to perform puncture operation, the puncture biopsy needle can be prevented from scratching the user or a patient, and the guide device has the function of guiding the puncture biopsy needle, can prevent the needle point from damaging in-vivo tissue, which does not need puncture, of the patient when the puncture biopsy needle enters the body of the patient, is beneficial for determining the portion needing puncture and improving the accuracy of blind operation, and prevents the puncture biopsy needle from repeatedly getting in and out of the body of the patient when the same portion is punctured many times to effectively relieve the pain of the patient.

Description

A kind of aspiration biopsy guide

Technical field

The present invention relates to the guiding device of puncture biopsy needle, particularly a kind of aspiration biopsy guide.

Background technology

Along with the development of modern medicine, the operation of aspiration biopsy is needed to get more and more clinically, quite most of aspiration biopsy is had to operate, clinician is needed to carry out aspiration biopsy with finger-guided puncture needle, as biopsy from the rectum prostate system puncture law, this kind of aspiration biopsy of doctor's finger-guided that needs operates, and there is following some problem:

1, in operation, puncture needle may scratch glove, and even injuring medical personnel may.

2, operator safely, effectively cannot judge puncture needle and guide the relative position relation between finger, especially when carrying out blind operation.

3, in blind operation, puncture needle directivity is bad.

4, in puncture biopsy needle turnover patient tract process, exposed needle point very easily injures patient's normal structure, as rectum, mucous membrane of anal canal.

5, for the tissue that some need multiple spot to puncture, such as prostate, puncture needle needs repeatedly, repeatedly to pass in and out patients anal canal, not only making patients's sense of discomfort in operation, and wound rectum, anus probability significantly improve.

Summary of the invention

The object of the invention is to the shortcoming overcoming prior art, the aspiration biopsy guide that a kind of structure is simple, easy to use is provided.

Object of the present invention is achieved through the following technical solutions: a kind of aspiration biopsy guide, comprises guide and fixture, and be provided with puncture biopsy needle installing hole in guide, fixture is connected with guide.

Described fixture is connected by rotating shaft with guide.

One end of described guide is provided with projection.

Described guide and fixture are medical material manufacture.

Described fixture is ring-type.

The present invention has the following advantages:

1. the current ripe medical material manufacture of a complete set of materials'use of this guide, makes this guide smooth surface, can realize disposable or use repeatly, and can avoid infection;

2. guide is fixed on finger by fixture, centered by rotating shaft, can do the angle change of certain limit, to be applicable to different puncture angle demands;

3. guide can pass through for the puncture needle of different thicknesses, meet the puncture needs of different tissues, organ, in aspiration biopsy process, after often completing the aspiration biopsy of a point, only need exit puncture biopsy needle from guiding device, and guide hands and puncture guide can stay in patient body, after determining next point of puncture, puncture needle enters from guiding tube again, avoid traditional aspiration biopsy operation, repeatedly pass in and out patient's rectum, improve the efficiency of aspiration biopsy, significantly reduce the generation of Accessory injury in aspiration biopsy, effectively reduce patient's sense of discomfort;

4. there is the projection that can supply tactilely-perceptible guide front end, and convenient operation person, under blind operational circumstances, determining point of puncture by touching projection, setting up puncture procedure passage, improves the accuracy of puncture;

5. fixture can prevent puncture guide accidental in patient body;

6. make puncture biopsy needle load guide inherence and carry out aspiration biopsy, operator and patient effectively can be protected to be scratched, avoid accidental injury, prevent nosocomial infection.

Accompanying drawing explanation

Fig. 1 is a kind of structural representation of aspiration biopsy guide;

In figure, 1-guide, 2-puncture biopsy needle installing hole, 3-rotating shaft, 4-fixture, 5-is protruding.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:

As shown in Figure 1, a kind of aspiration biopsy guide, comprises guide 1 and fixture 4, is provided with puncture biopsy needle installing hole 2 in guide 1, and in order to make puncture biopsy needle pass, fixture 4 is connected with guide 1.

In the present embodiment, described fixture 4 is connected by rotating shaft 3 with guide 1, can, after this guide is worn on user finger, make guide 1 can do the swing of certain angle, to adapt to different puncture angle demands with this.

In the present embodiment, one end of described guide 1 is provided with protruding 5, with this can convenient operation person under blind operational circumstances, determining point of puncture by touching projection, setting up puncture procedure passage, improve the accuracy of puncture.

In the present embodiment, described guide 1 and fixture 4 are medical material manufacture, as ABS, TPU, PVC etc., medical material is used to protect from infection, and the guide 1 that medical material is produced and fixture 4 smooth surface, can reduce friction, avoid causing patient uncomfortable.

In the present embodiment, described fixture 4 is ring-type, this guide can be made to be worn on user finger, and this guide can be prevented to be lost in patient body by fixture.

Work process of the present invention is as follows: this guide is worn on finger by fixture 4 by medical worker, protruding 5 near the finger end worn, finger is carried guide 1 and stretches in patient body by medical worker, finger due to medical worker can touch protruding 5, therefore point of puncture can be determined easily, again puncture biopsy needle is passed puncture biopsy needle installing hole 2 to enter in patient body, can prevent in the process of puncture with this, puncture biopsy needle scratches patient or medical worker, puncture biopsy needle is taken out after aspiration biopsy completes, the finger of guide 1 and medical worker is stayed in patient body and is found next point of puncture, again other puncture biopsy needle is carried out aspiration biopsy through guide 1, the finger of medical worker can be avoided repeatedly to pass in and out in patient body, cause patient uncomfortable.
