Problems solved by technology

There are benign and malignant bone tumors. Benign bone tumors are easy to cure and have a good prognosis. Malignant bone tumors develop rapidly, with poor prognosis and high mortality. Commonly used bone tumor tissue sampling and inspection methods include needle biopsy, incisional biopsy, and frozen bone tumors. Sections, paraffin sections, etc. are often checked by needle aspiration biopsy, which is less traumatic, but the existing needle biopsy equipment has inaccurate positioning, and it is easy to cause debris when cutting tissues, which will pollute other normal tissues. It is easy to cause loss during the process and affect the patient's condition

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a bone tumor pathological tissue extraction device with a cutting device. Background technique [0002] Bone tumors are tumors that occur in the bone or its accessory tissues. There are benign and malignant bone tumors. Benign bone tumors are easy to cure and have a good prognosis. Malignant bone tumors develop rapidly, with poor prognosis and high mortality. Commonly used bone tumor tissue sampling and inspection methods include needle biopsy, incisional biopsy, and freezing. Sections, paraffin sections, etc., are often checked by needle aspiration biopsy, which is less traumatic, but the existing needle biopsy equipment has inaccurate positioning, which is easy to cause debris when cutting tissues, and pollutes other normal tissues. It is easy to cause loss during the process and affect the patient's condition. Contents of the invention [0003] The purpose of the...
