Abstract
The invention provides an automatic extraction type sampling probe. The automatic extraction type sampling probe comprises an internal needle and an external needle, wherein the tail of the internal needle is connected with a needle tubing of the internal needle; the tail of the external needle is connected with a needle tubing of the external needle; the internal needle and the needle tubing of the internal needle are arranged inside the external needle and the needle tubing of the external needle; an external sleeve is arranged outside the needle tubing of the external needle; and the tail portion of the external sleeve is connected with a handle. The automatic extraction type sampling probe is characterized in that the tail end of the needle tubing of the internal needle is connected with a vacuum bag. Living tissues with unknown nature in the upper digestive tract, the lower digestive tract, the respiratory tract and other systems are sampled by the automatic extraction type sampling probe. Through the analysis of pathology, the automatic extraction type sampling probe can be performed by one hand. The vacuum bag is used for extracting the tissues. Concave grooves and micro-pores bring convenience for sampling. The sampling is convenient and the operation is simple by using the automatic extraction type sampling probe.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of from odd test sampling probe.
Background technology
Sampling probe is usually applied to and samples for the living tissue of uncertain property in upper and lower digestive tract, respiratory tract and other system clinically, carries out pathological analysis.Under normal circumstances, in the process of operation sampling probe, operator needs bimanualness apparatus, and a hand steered firmly apparatus, another hands completes the operation of suction sampling, operates comparatively loaded down with trivial details.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of from odd test sampling probe.
In order to solve the problems of the technologies described above, the invention discloses a kind of from odd test sampling probe, comprise interior pin and outer pin, pin needle tubing in described interior pin backshank connects, described outer pin backshank connects outer pin needle tubing, and described interior pin and interior pin needle tubing are located at outer pin and outer pin needle tubing is inner, described outer pin needle tubing outside is provided with trocar sheath, described trocar sheath afterbody connecting handle, is characterized in that, described interior pin needle tubing tail end connects vacuum bag.
In the present invention, the interior pin needle tubing before described vacuum bag is provided with one-way check valve.
In the present invention, described interior pin be circumferentially with more than one hexagon thieff hatch.
In the present invention, described interior pin is provided with barb structure, and the corresponding surface of described barb structure is provided with circular hole.
In the present invention, described vacuum bag is made up of soft material.
In the present invention, described interior pin needle tubing end is provided with a female Luer.
Beneficial effect: the present invention is used for sampling the living tissue of uncertain property in upper and lower digestive tract, respiratory tract and other system clinically, through property pathological analysis, one-hand operation of the present invention, by vacuum bag aspirates tissue, groove on interior pin and aperture can conveniently sample, the present invention samples conveniently, simple to operate.
Accompanying drawing explanation
To do the present invention below in conjunction with the drawings and specific embodiments and further illustrate, above-mentioned or otherwise advantage of the present invention will become apparent.
Fig. 1 is structural representation of the present invention;
