Abstract

The utility model relates to a tumor sampling device. The tumor sampling device comprises a pipe body, a pipe cap, a propelling rod, a buffering spring, a pressure plate, a scraper knife rod, a scraper knife and a needle, wherein the pipe cap is fixed on the pipe body, the buffering spring is matched with the inner diameter of the pipe body, the propelling rod is matched with the inner diameter of the buffering spring, two ends of the propelling rod are respectively provided with a piston and a pressure handle, the pressure plate is arranged between the buffering spring and the pipe cap, the pressure plate is fixed on the propelling rod, the scraper knife rod is fixed in the center of the piston, the scraper knife is arranged on the scraper knife rod, a needle seat is arranged on the pipe cap, the pipe cap is in screw-thread fit with the pipe body, the needle is fixed on the needle seat, and the inner diameter of the needle is communicated with an inner cavity of the pipe body. The tumor sampling device not only is reasonable in structure and simple to operate, but also is convenient for separating to-be-detected tissues with small wound and capable of alleviating the working difficulty of the medical personnel and improving the working efficiency.

Description

Tumor sampler

Technical field

This utility model belongs to technical field of medical instruments, especially a kind of tumor sampler.

Background technology

Tumor is that body is under various carcinogenic factor effects, some cells of local organization lose the normal regulation to its growth on gene level, the abnormality that causes its clonal abnormality hypertrophy and form, but tumor is also divided into malignant tumor and benign tumor, just need to carry out sample analysis to inside tumor to the pathological analysis of tumor, while carrying out tumor biopsy sampling to patient clinically, can realize by scalpel, but because wound is large, bring misery to patient, therefore, mostly adopt at present syringe to sample, its principle is the negative pressure producing while extracting by syringe, draw tumor tissues, although this sampling method has advantages of that wound is little, but ordinary syringe syringe needle is round and smooth, pin chamber is narrow, after absorption, tissue to be checked enters pin intracavity and is not easy to be isolated, take out, increase work difficulty to medical worker.

Summary of the invention

In order to overcome the deficiencies in the prior art, this utility model provides a kind of tumor sampler, this tumor sampler is not only rational in infrastructure, easy and simple to handle, and can reach wound and littlely, convenient separate tissue to be checked, alleviate medical worker's work difficulty, the object of increasing work efficiency.

This utility model is to solve the deficiency that prior art exists, the technical scheme of taking is, comprise body, pipe cap, pushing ram, buffer spring, pressing plate, scraping cutter bar, scraper and syringe needle, wherein, with body fixing have a pipe cap, what coordinate with internal diameter of tube body has a buffer spring, pushing ram coordinates with buffer spring internal diameter, there are respectively piston and pressure handle in pushing ram two ends, between buffer spring and pipe cap, there is pressing plate, and pressing plate is fixed on pushing ram, scraping cutter bar is fixed in piston in the heart, on scraping cutter bar, there is scraper, on pipe cap, there is needle holder, pipe cap and body threaded engagement, syringe needle is fixed in needle holder, syringe needle internal diameter and communicating with tube cavity, described syringe needle front end tip lateral edges has blade, described scraper is prismatic, there is blade in its rib portion.

The beneficial effects of the utility model are: this tumor sampler is not only rational in infrastructure, easy and simple to handle, and can reach wound and littlely, convenient separate tissue to be checked, alleviate medical worker's work difficulty, the object of increasing work efficiency.

Below in conjunction with accompanying drawing, this utility model is further illustrated.

Brief description of the drawings:

Fig. 1 is topology view of the present utility model.

Detailed description of the invention

Detailed description of the invention of the present utility model is, comprise body 6,

pipe cap

4, 12, pushing ram 2, buffer spring 5, pressing plate 3, scraping cutter bar 8, scraper 9 and syringe needle 10, wherein, with body 6 fixing have a

pipe cap

4, 10, what coordinate with body 6 internal diameters has a buffer spring 5, pushing ram 2 coordinates with buffer spring 5 internal diameters, there are respectively piston 7 and pressure handle 1 in pushing ram 2 two ends, between buffer spring 5 and pipe cap 4, there is pressing plate 3, and pressing plate 3 is fixed on pushing ram 2, scraping cutter bar 8 is fixed in piston 7 in the heart, on scraping cutter bar 8, there is scraper 9, on pipe cap 12, there is needle holder 11, pipe cap 12 and body 6 threaded engagement, syringe needle 10 is fixed in needle holder 11, syringe needle 10 internal diameters and communicating with body 6 inner chambers, described syringe needle 10 front end tip lateral edges have blade, described scraper 9 is prismatic, there is blade in its rib portion, the operation principle of described tumor sampler is, in the time using, syringe needle 10 is inserted in body tumor, slowly press the pressure handle 1 on pushing ram 2, at this moment, pressing plate 3 on pushing ram 2 presses buffer spring 5 and compresses, piston 7 moves ahead, scraper on scraping cutter bar 89 is pushed in syringe needle 10 internal diameters, scraper 9 and lean out syringe needle 10 front end tips, scraper 9 and syringe needle 10 front end tip lateral edges blades coordinate will be after sampling separate tissue, slowly unclamp pressure handle 1, buffer spring 5 opens, pull piston 7 to do drawback movement, the interior formation negative pressure of body 6 when piston 7 backhaul, the sampling tissue for the treatment of cutting down is sucked in body 6 inner chambers, screwing off pipe cap 12 takes out and treats sampling tissue, complete sampling operation.

Claims

1. a tumor sampler, comprise body, pipe cap, pushing ram, buffer spring, pressing plate, scraping cutter bar, scraper and syringe needle, it is characterized in that: with body fixing have a pipe cap, what coordinate with internal diameter of tube body has a buffer spring, pushing ram coordinates with buffer spring internal diameter, there are respectively piston and pressure handle in pushing ram two ends, between buffer spring and pipe cap, there is pressing plate, and pressing plate is fixed on pushing ram, scraping cutter bar is fixed in piston in the heart, on scraping cutter bar, there is scraper, on pipe cap, there is needle holder, pipe cap and body threaded engagement, syringe needle is fixed in needle holder, syringe needle internal diameter and communicating with tube cavity.
