Background technique

Bone tumors are tumors that occur in the bone or its subsidiary tissues, and can be divided into benign and malignant. Benign bone tumors are easy to cure and have a good prognosis; malignant bone tumors develop rapidly, have poor prognosis, and high mortality. Malignant bone tumors are divided into primary Secondary malignant bone tumors are secondary malignant bone tumors that metastasize from malignant tumors in other tissues or organs in the body to bones through blood circulation and lymphatic system. The characteristics of cell morphology, but its ecology and behavior are destructive to tumors, generally limited and easy to cure.

At present, when it is used in practice, medical staff often use hand-held lesion parts, and randomly find a support as a support pad to cut out, because the bone is hard and cannot be effectively fixed, often resulting in unsatisfactory material collection; even if the existing sampling fixed bracket , because of its inflexible structure, some positions of the fixed bones are blocked by the fixing bracket, so it is inconvenient to cut out, and the bones need to be removed and placed again; and when fixing bones with special shapes such as the skull and spine, only the bones can be fixed.
