Abstract

The invention discloses a device for locating a CT (Computed Tomography)-guided percutaneous biopsy and seed implantation template. The device comprises a CT bed, a support, a first sliding rail, first sliding blocks, a first motor, a first screw rod, first nuts, a connecting plate, a second sliding rail, a second sliding block, a second motor, a second screw rod, a second nut, a moving plate, a third motor and a controller. The device for locating the CT-guided percutaneous biopsy and seed implantation template has the advantages of ingenious structure, powerful functions and simple operation; by using the device, the puncturing and locating accuracy can be greatly improved; moreover, the working efficiency of medical workers is improved.

Description

technical field [0001] The invention relates to a positioning device, in particular to a device for puncture biopsy and particle implantation template positioning under the guidance of CT. Background technique [0002] At present, the hospital conducts biopsy of lesions in the body under the guidance of CT, and uses 3D printed needle track templates to treat tumor patients with particle implantation. Although the 3D printed needle track template solves the matching problem between the needle track and the preoperative TPS system simulation, for organs such as the lungs and liver that are constantly moving under CT with breathing, there will be a relative difference between the needle track template and the tumor in the body. Problems with changing positions. Once the positioning of the needle track template is deviated relative to the tumor, all implanted needles will be placed in the wrong position, resulting in treatment failure and puncture risk. In view of the above de...
