Abstract

The invention relates to the technical field of biopsy devices, and concretely relates to a safe bone tumor biopsy device. The device comprises a mounting box, a rectangular fixing column is vertically arranged on the surface of the mounting box, a rectangular sliding groove is formed in one side of the rectangular fixing column, a cylindrical mounting bin is formed in the rectangular fixing column, a second spring is arranged in the cylindrical mounting bin, a fixing block is arranged on the other side of the rectangular fixing column and located on the lower middle portion, a locking block is slidably connected to the side face of the fixing block, and a sampling puncture needle body is movably connected to the side face of the rectangular fixing column. The position needing to be sampled is determined through a positioning table, the sampling puncture needle body is inserted into the body of a patient to sample, a pathological specimen can be obtained through a sampling area, a mixture of polyvinyl alcohol and hydrogel in the embolism storage bin is sprayed out from an instantaneous release ring through a micro water pump to timely block a needle hole, and the sampling punctureneedle is thin to avoid the problem of a large incision.

Description

technical field [0001] The invention relates to the technical field of biopsy devices, in particular to a safe bone tumor biopsy device. Background technique [0002] The formulation of bone tumor treatment plans depends on the definite diagnosis of the disease. The diagnosis of bone tumors mainly depends on clinical manifestations, imaging manifestations, and pathological results. The pathological results are the criteria for the diagnosis of benign and malignant bone tumors and pathological classification; Given the need for an incisional biopsy, which yields sufficient specimens but carries the risk of large incisions and pathological work, we propose a safe bone tumor biopsy device. Contents of the invention [0003] The purpose of the present invention is to provide a safe bone tumor biopsy device to solve the problem in the background art that large incisions are likely to be caused when pathological specimens are obtained through incisional biopsy. [0004] To achi...
