Abstract

The invention relates to the technical field of medical instruments, in particular to a bone tumor pathological tissues extractor with a cutting device. The extractor comprises an extractor body. The extractor body comprises a needle and a T-shaped handle. A top end of the needle is provided with a circular connecting block. The middle of the circular connecting block is provided with an inner tube holder. The needle is in a cavity form. A bottom end of the needle is a tip end which is provided with a circular hole. A suction inner tube is arranged in the needle. A bottom end orifice of the suction inner tube is connected with the circular hole. An upper end orifice of the suction inner tube is connected with the inner tube holder in the middle of the circular connecting block. The inner tube having a suction function is arranged in the needle, the cutting device is arranged on the lower portion of one side of the needle, and thus a tissue sample and sample liquid are acquired at a time. The extractor is simple in structure and convenient to operate, acquisition speed is high, work efficiency is high, and pain of a patient is greatly relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone tumor pathological tissue extraction device with a cutting device. 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. A biopsy is required to obtain a tissue sample during retrieval, and a biopsy needle is generally used to obtain the sample. However, the biopsy needles used in hospitals now generally puncture to the bone, fix the directional catheter, then take out the puncture needle and introduce it...
