Abstract

The invention discloses a bone tumor sampling fixing device, which comprises an arc seat. A ring is arranged above the arc seat and in rotational fit with the arc seat, a plurality of column barrels are annularly distributed on the inner periphery of the ring, and inner holes of the column barrels are in slide fit with corresponding steel columns. A slide seat is connected to the lower end of a vertical column which is connected to the lower end of the arc seat, and the slide seat is in slide fit with a slide rail at the lower end of the slide seat. The ring can be connected with the arc seatthrough a pair of first connection mechanisms, the steel columns can be connected with the corresponding column barrels through second connection mechanisms, and the slide seat can be connected with the slide rail through a pair of third connection mechanisms. The bone tumor sampling fixing device has advantages that due to adoption of the structure, reliable connection between the arc seat and the ring, between the column barrels and the steel columns and between the slide seat and the slide rail can be realized, reliable bone fixation is realized, and convenience in sampling is achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a bone tumor sampling and fixing device. Background technique [0002] 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 a poor prognosis, and have a high mortality rate. 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. [0003] When the pathology department makes a pathological report on bone tumors, it needs to first sample the bone from the lesion of the patient's bone tumor to ...
