Bone tumor specimen sampler

Abstract

The invention relates to the technical field of specimen sampling, in particular to a bone tumor specimen sampler which comprises a device body. The device body comprises a first mounting frame, a supporting plate is fixedly mounted at the top of the first mounting frame, and an electric push rod is integrally mounted at the bottom end of the supporting plate. A second mounting frame is integrally mounted at the bottom end of the electric push rod, a motor is fixedly mounted on one side of the bottom end of the second mounting frame, a rotating rod is fixedly connected to the output end of the motor, the end, away from the motor, of the rotating rod is rotationally connected with the other side of the bottom end of the second mounting frame through a bearing, and a blade is fixedly mounted on the surface of the rotating rod. And a pressing assembly is fixedly mounted at the top end of the first mounting frame. By arranging the pressing assembly and controlling the lead screw, the pressing plate is tightly attached to the bone placed on the placing table, so that the pressing plate can press the bone, the stability during bone cutting is improved, the bone cutting quality is improved, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of specimen sampling, in particular to a bone tumor specimen sampler. Background technique [0002] Bone tumors are tumors that occur in the bone or its subsidiary tissues. They 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. The pathological report of bone tumors needs to be passed Bone tumor pathology specimens are made, so it is necessary to sample the patient's bones. [0003] Since there are no special tools and the bones are very hard, it is difficult to obtain materials. At present, most of the materials are obtained by hand. When operating, hold the bones and find a hard object as a support pad, which often leads to unstable fixation. , The problem of inaccurate positioning leads to irregular sampling surfaces, which makes it difficult to meet the sam...

Problems solved by technology

[0003] Since there are no special tools and the bones are very hard, it is difficult to obtain materials. At present, most of the materials are obtained by hand. When operating, hold the bones and find a hard object as a support pad, which often leads to unstable fixation. , the problem of inaccurate positioning, resulting in irregular sampling surface, it is difficult to meet the sampling requirements, and then affect the quality of slices, therefore, it is necessary to design a bone tumor specimen sampler to solve the above problems
