Abstract

The utility model relates to a pleural biopsy sampler which is provided with a needle tube having a tip at the front end; the side at the front end of the needle tube is provided with a window which is arc-shaped at the lower side, the window is articulated with a sampling knife which has the size corresponding to that of the window and is provided with a cutting edge at the bottom edge, and the inner side of the sampling knife is fixedly provided with a support rod provided with a circular ring at the end part; the lower section of the needle tube is internally provided with a tube plug, thecenter of the tube plug is provided with a guide hole and a push-and-pull rod; and a triangle bend is formed at the upper section of the push-and-pull rod, and the hypotenuse of the triangle bend is penetrated and sheathed inside the circular ring arranged at the end part of the support rod at the inner side of the sampling knife. The pleural biopsy sampler is reasonable in design, can be used forsampling when in pleural biopsy, and has the advantages of small wound, easy restoration, less pain for the patients and reliable sampling.

Description

A kind of biopsy of pleura sampler

Technical field:

This utility model belongs to the medical apparatus technical field, relates to a kind of biopsy of pleura sampler.

Background technology:

In the prior art, biopsy of pleura sampling mainly contains two kinds of surgical method and internal medicine biopsy needle methods.The surgical method broad view, sampling is reliable, but its wound is big, recovers slow, often causes certain misery to patient.Internal medicine biopsy needle method, wound is little, and patient's misery is little, but it is to utilize the lateral breach of biopsy needle to sample, its sampling poor reliability sampling quantity is less, even often gets less than sample, is difficult to satisfy the requirement of biopsy.

Summary of the invention:

The purpose of this utility model provides a kind of novel biopsy of pleura sampler, in order to effectively to overcome the above-mentioned defective of prior art existing in prior technology.The purpose of this utility model realizes with following technical scheme: it has a front end is the aciculiform pipe at tip, the front end side of this aciculiform pipe has a bottom and is arcual window, be hinged with a size, the end corresponding with window on the window along the sampling knife of being with cutting edge, the inboard of this sampling knife is fixed with the pole of an end band annulus; Be provided with pipe close in the hypomere of aciculiform pipe, the center of pipe close has pilot hole, and push-pull bar is housed, the epimere triangularity bending of this push-pull bar, and the hypotenuse of its bending is set in the annulus of above-mentioned sampling knife medial branch boom end.

This utility model is reasonable in design, is used for the biopsy of pleura sampling, and wound face is little, recovers easily, and patient's misery is little, and sampling is reliable.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model

The specific embodiment:

Accompanying drawing has provided a specific embodiment of the present utility model, below in conjunction with accompanying drawing this utility model is elaborated: with reference to the accompanying drawings, 5 is aciculiform pipes among the figure, front end is most advanced and sophisticated, the front end side of this aciculiform pipe 5 has the following arcual window that is, be hinged with size, the end corresponding with window on the window along the sampling knife 4 of being with cutting edge, the inboard of this sampling knife 4 is fixed with the pole 3 of an end band annulus; Be provided with pipe close 1 in the hypomere of aciculiform pipe 5, the center of pipe close 1 has pilot hole, and push-pull bar 2 is housed, the epimere triangularity bending of this push-pull bar 2, and the hypotenuse of its bending is set in the annulus of above-mentioned sampling knife 4 inboard poles 3 ends.During use, earlier push-pull bar 2 is upwards pushed away, move on the triangle hypotenuse of push-pull bar 2 epimeres, the pole 3 that drive is set on the push-pull bar 2 epimere hypotenuses is moved to the center of aciculiform pipe 5, make sampling knife 4 be in closed condition, puncture then, make sampling knife 4 arrive the pleura sampling location, and then spur push-pull bar 2 downwards, the hypotenuse of push-pull bar 2 is made a call to 4 by the pole 3 of sampling knife 4 inboards with sampling knife and is opened, and outwards extract the aciculiform pipe 5 of puncture this moment, in the process that sampling knife 4 is pulled out outside aciculiform pipe 5, the biopsy samples of cutting is also taken out of thereupon, thereby realizes the biopsy sampling process.

Claims

A kind of biopsy of pleura sampler, it is characterized in that it has a front end to be most advanced and sophisticated aciculiform pipe (5), the front end side of this aciculiform pipe (5) has a bottom and is arcual window, be hinged with a size, the end corresponding with window on the window along the sampling knife (4) of being with cutting edge, the inboard of this sampling knife (4) is fixed with the pole (3) of an end band annulus; Be provided with pipe close (1) in the hypomere of aciculiform pipe (5), the center of pipe close (1) has pilot hole, push-pull bar (2) is housed, the epimere triangularity bending of this push-pull bar (2), the hypotenuse of its bending is set in the annulus of the inboard pole of above-mentioned sampling knife (2) (3) end.
