Abstract

The utility model relates to a novel pleura biopsy needle which belongs to medical apparatus. A needle core or biopsy brush which has a semispherical front bulkhead is provided in an inner cutting needle tube. The biopsy needle with a tee joint is sleeved outside the inner cutting needle tube. A sleeve puncture needle is sleeved outside the biopsy needle. The novel pleura biopsy needle has the following advantages: novel structure, simple manufacture and operation of the pleura biopsy needle, capability of randomly fetching a plurality of blocks of biopsy tissues in a same operation process, high success rate, simple operation, high safety, reduced pain to the patient, capability of greatly helping pleura disease analysis and diagnosis, lower clinical cost, and significant application prospect and meaning.

Description

Novel biopsy of pleura pin

Technical field

This utility model belongs to medical apparatus and instruments, refers in particular to a kind of biopsy of pleura pin, is used to diagnose the cause of disease of hydrothorax.

Background technology

The hydrothorax patient is on the increase in recent years, especially tuberculosis property hydrothorax and cancerous hydrothorax, and the specific aim treatment needs pathological diagnosis.Part pleural diseases can obtain clinical diagnosis according to the reaction of clinical manifestation, chest X-ray, hydrothorax laboratory examination and experimental treatment, but still some patient can not get making a definite diagnosis and delay treatment, and these patient's considered are in time gone biopsy of pleura.Cost an arm and a leg through the biopsy of internal medicine thoracoscope, be not suitable for extensively carrying out, at present domestic most employing pleura enclosed biopsy.The biopsy of pleura pin of present domestic extensive use is fairly simple: the crochet hook of band nook closing member, and it is little to draw materials, and tears pleura easily, and the pneumothorax incidence rate is high.The external 2 kinds of biopsy of pleura pins that have commonly used at present: Cope pin, Abrams pin.The Cope pin is made up of trocar tube, crochet hook, nook closing member, advantage: 1 puncture can be at different azimuth biopsy pleura, and shortcoming is that the pleura BIAO and BEN of obtaining is little, and it is higher that the pneumothorax rate takes place.The Cope pin is made up of the trocar, inscribe pin and the nook closing member of buckle.Advantage is that the pleura BIAO and BEN of obtaining is big, and the pneumothorax incidence rate is low, and shortcoming is that puncture only can obtain BIAO and BEN one time 1 time.Also there is above-mentioned shortcoming in various degree in domestic novel biopsy needle at present.

Summary of the invention

This utility model provides a kind of novel biopsy of pleura pin, to solve little, the higher shortcoming of generation pneumothorax rate of film BIAO and BEN that present biopsy of pleura pin exists.

The technical scheme that this utility model is taked is: the front end plug is hemispheric nook closing member or the biopsy brush is positioned at incised needle tubing inside, and the biopsy needle of band threeway is socketed in the outside of incised needle tubing, and the sleeve pipe Puncture needle sleeve is connected on the biopsy needle outside.

In this utility model, sword is arranged, outward turning grooving one side band sword on the outward turning grooving front end buckle of the biopsy needle of band threeway, this hook.

In this utility model, the top of incised needle tubing has annular sword, and there is the inward turning grooving its front portion, and the relative outward turning grooving of this inward turning grooving band sword one side has sword.

In this utility model, the front end plug is the hemisphere external diameter and the incised pin internal diameter precision-fit of hemispheric nook closing member, and the external diameter of nook closing member is less than incised pin internal diameter.

In this utility model, the seal wire external diameter of biopsy brush is less than incised pin internal diameter, and flexible brush adopts memory metal.

The utility model has the advantages that novel structure, this biopsy of pleura pin is made and operates all simpler and easy, in same operating process; The piece pleura of can arbitrarily peeking, success rate is high, simple to operate, safety; Reduce the patient suffering; Diagnosis and Differential Diagnosis to pleural diseases provide great help, and clinical expense is lower, application prospect and significant.

The specific embodiment

Embodiment 1

The front end plug is hemispheric nook closing member 4 and is positioned at incised needle tubing 3 inside; The biopsy needle 2 of band threeway is socketed in the outside of incised needle tubing 3, and sleeve pipe puncture needle 1 is socketed in biopsy needle 2 outsides, on the outward turning grooving front end buckle 201 of the biopsy needle 2 of band threeway, this hook sword 203 is arranged; Outward turning grooving one side band sword 202; The top of incised needle tubing 3 has annular sword 301, and there is the inward turning grooving its front portion, and the relative outward turning grooving of this inward turning grooving band sword one side has sword 302; The front end plug is the hemisphere external diameter and the incised pin internal diameter precision-fit of hemispheric nook closing member 4, and the external diameter of nook closing member is less than incised pin internal diameter.

Embodiment 2

Biopsy brush 5 is positioned at incised needle tubing 3 inside; The biopsy needle 2 of band threeway is socketed in the outside of incised needle tubing 3, and sleeve pipe puncture needle 1 is socketed in biopsy needle 2 outsides, on the outward turning grooving front end buckle 201 of the biopsy needle 2 of band threeway, this hook sword 203 is arranged; Outward turning grooving one side band sword 202; The top of incised needle tubing 3 has annular sword 301, and there is the inward turning grooving its front portion, and the relative outward turning grooving of this inward turning grooving band sword one side has sword 302; Seal wire 501 external diameters of biopsy brush 5 are less than incised pin internal diameter, and flexible brush 502 adopts memory metal.

In the present embodiment, can omit the incised pin, as shown in Figure 2, hairbrush is located immediately in the biopsy needle of band threeway.

This utility model:

1, on the outer tube wall of the biopsy needle of puncture needle and band threeway scale is arranged, be convenient to observe the degree of depth that gets into thoracic wall.

The tee T side can be with the vacuum suction hydrothorax when 2, puncturing, and after clear and definite biopsy needle got into pleural space, operation biopsy needle, incised pin can be avoided pneumothorax as far as possible.

3, puncture once can be got pleura in different azimuth, and it is changeable to get BIAO and BEN, and it is less to hook up pleura, and rotary-cut pleura is bigger.

4, the half-cylindrical plug of nook closing member far-end can prevent that the pleura of cutting from losing.

5, the flexible hairbrush that utilizes memory metal to do can be brushed and get pleura and do pathology.
