Bone tumor sampling and fixing device

Abstract

The invention discloses a bone tumor sampling and fixing device, which comprises a workbench; and two supporting columns are symmetrically arranged at the two ends of the surface of the top of the workbench. The top ends of the two supporting columns are connected with arc-shaped bases, the top end of each arc-shaped base is rotationally connected with a circular ring, a plurality of column casings are connected to the inner wall of each circular ring at equal intervals in a surrounding mode, a rack plate is connected to the inner wall of each column casing, and a steel column is arranged in each column casing. First driving motors are started to work at the same time; the first driving motors drive the first driving wheels to rotate; the first driving wheels drive first driven wheels to rotate through belts; the first driven wheels and the first driving wheels drive the worm wheels to rotate through worms, so that the worm wheels are engaged with the rack plates to rotate, the steel columns can move inwards until a bone to be sampled is completely fixed and clamped, and the situation that the bone is loosened in the process of sampling the bone to be sampled can be prevented.

Description

technical field [0001] The invention relates to the technical 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 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. [0003] 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 b...

Problems solved by technology

[0003]At present, when it is used in practice, medical personnel often use the hand-held lesion part, and randomly find a support as a support pad to cut, because the bone is hard and cannot be effectively Fixed, often results in unsatisfactory material collection; even the existing sampling fixed bracket, because of its inflexible structure, some positions of the fixed bone are blocked by the fixed bracket, so it is inconvenient to cut, and the bone needs to be removed and placed again; , spine and other special-shaped bones, the bones can only be placed at certain specific angles, and the bones cannot be placed at any angle at will, which makes it difficult for medical staff to work smoothly, requiring many operations, time-consuming and labor-intensive
