Abstract

The invention discloses a puncture positioning device for accurate positioning and guidance of a bone tumor surgery, in particular relates to the technical field of medical devices. The device comprises a moving body, wherein a controlling main machine is arranged on the top of the moving body, a single-chip microcomputer is arranged on one side of the controlling main machine, both sides of the top of the moving body are fixedly connected with a supporting table, the top of the supporting table is fixedly connected with a slide rod, an outer side of the slide rod is in sliding connection witha sliding sleeve, and an electric push rod is arranged between the sliding sleeve and the supporting table. By the adoption of the puncture positioning device for accurate positioning and guidance ofthe bone tumor surgery, the moving body is arranged, so that the device can be conveniently moved; the sliding sleeve slides on the outer side of the slide bar, a horizontal sliding sleeve slides onthe outer side of a cross frame rod, and a telescopic rod is flexible, so that omni-directional adjustment of a positioning box body is achieved; a puncture needle is inserted into a jack and a guidecolumn is placed in a slide way, and puncture data is input through the controlling main machine, so that a micro-motor is in transmission connection with a gear, and a meshing rack makes the punctureneedle move down. The device is simple is structure, is flexible to move, and can effectively carry out positioning and guidance, so that burden on medical workers and pain of a patient are relieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, the invention relates to a puncture positioning device for bone tumor surgery with accurate positioning and guidance. Background technique [0002] Bone tumors are tumors that occur in bones or their adjunct tissues, and can be divided into benign and malignant. Malignant bone tumors, also known as bone cancer, develop rapidly, with poor prognosis and high mortality. Malignant bone tumors are divided into primary and secondary. Malignant tumors from other tissues or organs in the body metastasize to Bone is a secondary malignant bone tumor, and 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 , when the oncology needle biopsy, the prior art is usually that the medi...
