Description

Tumor gene detection sampling device

Technical Field

The utility model relates to a tumour gene detection sampling device belongs to sampling test technical field.

Background

Although modern medicine has been developed and obviously advanced in recent decades, tumor is still an important problem which puzzles the present medicine, and it is an abnormal pathological change formed by that some cells of local tissues lose normal regulation and control of their growth at gene level under the action of various carcinogenic factors, resulting in clonal abnormal hyperplasia of the cells, and how to overcome tumor is always a key research topic in medical field. Tumor tissue differs from normal tissue from which it originates to a different degree, both in cell morphology and tissue structure, and this difference is called heterogeneity. Specifically, the abnormal shape is the morphological expression of abnormal differentiation of the tumor, and the small abnormal shape indicates a high degree of differentiation; a large heterogeneity indicates a low degree of differentiation. Tumors are classified into benign tumors and malignant tumors, wherein cancers are the most common malignant tumors, and malignant tumors are classified into epithelial-derived cancers and mesenchymal-derived sarcomas, and in malignant tumors, the proliferated cells can be proliferated to other parts besides being integrated into lumps. In actual clinical medicine, differentiation of the size of a lesion is a major histological basis for diagnosing a tumor and determining it as benign or malignant. Tumor tissue sampling analysis is required.

The existing tumor sampling mode mainly comprises the following steps: the scalpel is used for cutting and sampling and the injector is used for puncturing and sampling. The scalpel is used for sampling, so that the wound is large, pain is brought to a patient, the cost is high, the body damage is large, and the scalpel is generally used less at present. The sampling of the injector is insufficient, and in the process of taking out the tumor tissue sample, the sample easily slides off, so that the sampling failure is caused, and the working difficulty of medical staff is increased.

SUMMERY OF THE UTILITY MODEL

Tumor gene detection sampling device, the novel nipple rectifier comprises a cylindrical shel, be equipped with baffle and fly leaf through hinge connection in the barrel, baffle and barrel fixed connection, barrel one end is equipped with the end cover, the barrel other end is equipped with the syringe needle, syringe needle and barrel communicate each other, be equipped with the piston head between baffle and the end cover, the piston head is close to the baffle and simultaneously is equipped with the sealing layer, the piston head another side is equipped with the push rod, the push rod runs through the end cover setting, run through the push rod, the piston head, sealing layer and baffle are equipped with helical cutting knife, helical cutting knife includes the screw rod, the screw rod runs through the push rod, the piston.

Working process or working principle:

promote the push rod, the sealing layer leans on tight baffle and fly leaf, and the syringe needle impales, rotates the screw rod, and the helical blade begins the cutting, and the cutting is accomplished the back, back spiral screw rod, and the screw rod suitably retreats, and handheld push rod retreats, and the fly leaf is opened to piston head one side under the vacuum action, and the tumor sample gets into the barrel from the syringe needle, gets into the barrel rear end through the fly leaf, unscrews the end cover, and the back pushes away the push rod, takes out the sample and saves.

Preferably, the screw rod is connected with the push rod through threads. When the spiral blade is ensured to be pushed to cut, the pushing distance can be accurately controlled, and the pain of a patient is reduced.

Preferably, the other end of the push rod is provided with a push handle in a bending way towards one side, and the other end of the screw rod is provided with a cutting handle in a bending way towards one side. The pushing handle and the cutting handle are both bent at one side, so that mutual interference of the pushing handle and the cutting handle is avoided.

Preferably, a compression spring is arranged between the piston head and the end cover. The piston head is ensured to always press the movable plate when puncturing.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a set up fly leaf and piston head, realized the tumour sample cutting back, get into the barrel through the negative pressure effect, sample safe and reliable.
