Diseased cell tissue excision device capable of finely adjusting cutting area

Abstract

The invention relates to the technical field of medical cell cutting equipment, in particular to a diseased cell tissue excision device capable of finely adjusting the cutting area. The device comprises a fixed frame; an upper shell is vertically welded in the middle of the upper end surface of the fixed frame; and an extension rod is vertically welded downwards in the middle of the upper end surface of an inner cavity of the fixed frame. The device has the beneficial effects that by arranging multiple sets of circular ring cutting knives to be connected in a sleeved mode, repeated installation and disassembly of the knives are avoided, pollution to the knives is greatly reduced, meanwhile, quantitative adjustment is achieved, so that the cutting area is controlled, and research variablesare conveniently controlled; through cooperation of plug pins and threaded holes which are symmetrical longitudinally, adjustment of the position of an extrusion block is achieved, tissue cell cuttingis achieved through punching of a hydraulic cylinder, convenient adjustment of the cutting position is achieved, and the cutting efficiency is greatly improved; and meanwhile, through cooperation ofa camera and a display screen, real-time observation of the cutting position is achieved.

Description

technical field [0001] The invention relates to the technical field of cell cutting medical equipment, in particular to a device for cutting diseased cells and tissues that can finely adjust the cutting area. Background technique [0002] In the research of diseased cell tissue, in order to realize repeated research and multiple data detection, it is necessary to cut the tissue cells multiple times during the research process, and due to the different variables of the research, the size of the tissue cells required for cutting Also different. [0003] Due to the small volume of tissue cells, the adjustment of the cutting area during cutting is usually small. In the existing fine-tuning for different cutting areas, the area of ​​the cutting knife is usually changed to obtain tissue cells of different areas. However, due to the volume of the cutting knife Smaller, the installation is more difficult, and because of the large amount of research data, multiple installation and d...

Problems solved by technology

[0003] Due to the small volume of tissue cells, the adjustment of the cutting area during cutting is usually small. In the existing fine-tuning of different cutting areas, the area of ​​the cutting knife is usually changed to obtain tissue cells of different areas. However, due to the volume of the cutting knife Smaller, more difficult to install, and due to the large amount of research data, multiple installation and disassembly are likely to pollute the cutting device, thereby increasing the research error

[0004] Therefore, a diseased cell tissue resection device that can fine-tune the cutting area is provided to solve the problem of fine-tuning and contamination of cut tissue cells
