Abstract

The invention discloses an adjustable bone tumor pathological specimen sampling fixator which comprises a workbench, a rotating shaft and a worm gear, a guide block is slidably mounted in a first sliding groove, a mounting frame is fixedly mounted at the top end of a supporting frame, and a first worm and a second worm are rotatably mounted between the mounting frame and the workbench. One end of the first worm and one end of the second worm are in transmission connection with the output end of a first motor and the output end of a second motor respectively, the two ends of the worm gear are in meshing transmission with the first worm and the second worm respectively, one end of the rotating shaft is fixedly installed in the worm gear, and the middle of the rotating shaft is rotationally connected with the guide block. A rotating frame is fixedly installed at the end, away from the worm gear, of the rotating shaft, and a movable clamping mechanism is installed in the rotating frame. Through meshing transmission cooperation of the first worm and the second worm with the worm gear, a clamped bone specimen can be lifted and rotated, and pathological specimen sampling can be conveniently carried out on different positions of the bone specimen.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an adjustable bone tumor pathological specimen collection fixer. Background technique [0002] Bone tumors are tumors that occur in the bone or its accessory tissues. There are 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 and secondary. Secondary malignant bone tumors are secondary malignant tumors that metastasize from other tissues or organs in the body to bones through the blood circulation and lymphatic system. There is another type of lesion called tumor-like lesions. The tissue of tumor-like lesions does not have the characteristics of tumor cell morphology, but its ecology and behavior are destructive to tumors. It is generally limited and easy to cure. [0003] The pathological report of bone tumors needs to...
