Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0017] see Figure 1-3 , the present invention provides a technical solution: a novel tumor sampling device, including a housing assembly 10, a sampling assembly 20 and a collection assembly 30, the housing assembly 10 includes a protection cylinder 11, a guide tube 12 and a fixing bolt 13, the right side of the protection cylinder 11 The side is provided with a fixed bolt 13, and the protective cylinder 11 is screwed and fixed with the fixed bolt 13. The righ...

The invention discloses a novel tumor sampling device. The novel tumor sampling device comprises a shell component, a sampling component and a collecting component and is characterized in that the shell component comprises a protective tube, a guide tube and a fixing bolt, the fixing bolt is arranged on the right side of the protective tube, the protective tube is fixedly connected with the fixingbolt in a threaded manner, and the guide tube is arranged on the right side of the fixing bolt. The novel tumor sampling device has the advantages that when the novel tumor sampling device is used for sampling the in-vivo tumor cell sample of a patient, a screw is driven to rotate by rotating a rod support to allow a piston to move in a piston tube at constant speed, negative pressure is generated inside the piston tube at the moment, tumor cells are sucked into the piston tube at constant speed, and the possibility that the tumor cells are damaged by excessively large negative pressure is avoided; during tumor cell collecting, the tumor cells in the piston tube can be conveniently guided into an effusion tube through a circular through hole inside the piston tube, the effusion tube can be demounted from the piston tube by rotating the effusion tube after the tumor cell collecting, and accordingly staff can conveniently analyze the tumor cells.
Description
technical field [0001] The invention belongs to the technical field of tumors, in particular to a novel tumor sampling device. Background technique [0002] Tumor refers to the new organism formed by the proliferation of local tissue cells under the action of various tumorigenic factors, because this new organism is mostly in the form of space-occupying blocky protrusions, also known as neoplasm. Tumors are divided into benign tumors and malignant tumors. Cancer is a general term for malignant tumors. [0003] When sampling tumor cells, the original tumor sampler generally uses a piston-type vacuum tube to inhale tumor cells into the injection tube, but this method is likely to cause the cells to break during the inhalation process, thereby reducing the quality of sampling, which is harmful to users. bring inconvenience. Contents of the invention [0004] The purpose of the present invention is to provide a new tumor sampling device to solve the problem that the original...
