Abstract
Aiming to overcome the technical problem that the conventional syringe needle with low suction quantity cannot meet the required quantity for the tissue inspection, the utility model provides a sampling needle for tissue inspection, and belongs to the technical field of medical instruments. The sampling needle includes a needle body and a needle bed at the tail part of the needle body, wherein the front end of the needle body is a needle point with an inclined opening. The sampling needle for tissue inspection is characterized in that the inclined opening of the needle point of the needle body extends in the direction of the needle body to form a notch; and a cutting edge is arranged at the edge of the notch. The sampling needle has a simple structure, is simple and convenient to operate, overcomes the disadvantage that in the traditional tissue inspection, an operation for tissue cutting is needed and causes great pain to patients, and can be extensively applied in the tissue sampling.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically is meant a kind of tissue examination sampling syringe needle.
Background technology
At present, cytolgical examination and histological examination method are generally adopted in clinical inspection to tumor.Cytolgical examination is to do inspection with the cell of fine needle absorption affected area, and painful little, easy and simple to handle, prior art generally adopts entry needle.And will do histological examination the time, because that entry needle is drawn thing is less, the tissue substance deficiency of being drawn is used for histological examination, does therefore that histological examination is many need to cut the fritter tumor tissues through operation and check, has brought great misery to the patient.
Summary of the invention
The purpose of this utility model provides a kind of tissue examination sampling syringe needle, to overcome the technical problem that present injection needle absorption amount does not reach the histological examination demand for a short time, reaches the easy technical purpose of sampling operation when carrying out histological examination.
For realizing above-mentioned technical purpose; The technical scheme that this utility model adopts is: tissue examination sampling syringe needle; The needle stand that comprises needle body and needle body afterbody; The needle body front end is the needle point that has angle, it is characterized in that: described needle body extends a gap at needle point angle place to the needle body direction, and the edge of gap is provided with cutting edge.
The beneficial effect of this utility model is: because this sampling probe is provided with gap at the needle point place, increased the contact area of needle point with the sampling tissue, under action of negative pressure, sampling probe can take off the bigger stripping and slicing of organizing, and satisfies the histological examination demand.This sampling probe is simple in structure, easy and simple to handle, and having overcome traditional histological examination needs to cut the drawback that tissue causes the big misery of patient through operation, can be widely used in the sample of tissue operation.
Description of drawings
Accompanying drawing is the structural representation of this utility model.
Among the figure, 1, needle body, 2, needle stand, 3, needle point, 4, gap.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is described further.
Shown in accompanying drawing, tissue examination sampling syringe needle comprises the needle stand 2 of needle body 1 and needle body afterbody, and needle body 1 front end is the needle point 3 that has angle, and needle body extends a gap 4 at needle point angle place to the needle body direction, and the edge of gap 4 is provided with cutting edge.
During concrete operations, this syringe needle is connected with syringe, this syringe needle is thrust in the sampling tissue; Produce negative pressure through the pulling syringe, sampling is organized under the action of negative pressure inner through gap entering syringe needle on this syringe needle, the rotation syringe needle; Downcut through the cutting edge at the gap edge tissue of will taking a sample; Being organized in of being downcut is stranded in needle body inside under the suction function, syringe needle is extracted, and the stripping and slicing of organizing of being downcut is taken out of thereupon.
