Background technique

The patient's lesion needs to be sampled and biopsied, especially whether the tumor on the patient's body is benign or malignant, and the tumor needs to be taken out for treatment. The common method is to cut regular slices and press them, soak them in wax and seal them into hard blocks. In this way, it is easy to calculate the composition, ratio, and specific gravity for analysis and testing, and it is also conducive to the analysis of data such as the area and distribution of bacteria. The traditional sample mold is a mold frame sealed around the periphery, which is manually pressed with a pressing plate, and then soaked in wax to form a hard block, which is then sampled. In view of this, according to the complexity and particularity of biopsy sampling, the patent applicant has successfully designed a pathological biopsy sampling and cutting device that is successfully used for sampling stereotypes, fixing, adjusting width, and slicing. Prior art patent application number: CN201220475761, invention name: a tissue cutting biopsy needle, including coaxially arranged and matched needle core and trocar, the needle core is provided with a cutting groove near the end of the needle core, and the trocar end The trocar tail passes through the front of the needle holder and is fixed to the movable seat.
