Abstract

The CT-guided puncture positioning and guiding device comprises a protractor, the protractor comprises a semicircular protractor body, a semicircular through hole is formed in the protractor body, the diameter of the through hole and the diameter of the protractor body are overlapped, the circle centers of the through hole and the protractor body are the same point, and a hanging needle is hung at the circle center of the through hole. A rotatable longitudinal adjusting plate is arranged at the arc center of the through hole, two limiting plates are installed at the lower end of the longitudinal adjusting plate, the limiting plates are symmetrically installed on the two sides of the striding seam, and the limiting plates make contact with the protractor. According to the method, the included angle between the puncture needle and the flat scanning vertical plane can be determined by determining the flat scanning vertical plane where the puncture needle is located, the included angle between the puncture needle on the flat scanning vertical plane and a vertical line and the direction perpendicular to the flat scanning plane, accurate positioning from multiple directions is achieved, and clear reference assistance is provided for CT-guided puncture operation; the puncture rate can be improved, the complication rate can be reduced, the exposure of radiation dose of a patient can be reduced, and the puncture operation time can be shortened by positioning the direction of the puncture needle.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a CT-guided puncture positioning and guiding device and a method thereof. Background technique [0002] With the advancement of medical technology, CT-guided percutaneous biopsy or treatment has become an important clinical diagnosis and treatment operation, such as respiratory professional CT-guided percutaneous lung biopsy, pain department for sympathetic nerve modulation requires CT positioning after puncture, intrahepatic The pathological diagnosis of space-occupying lesions requires CT-guided percutaneous liver biopsy, which has high diagnostic, differential diagnosis, and therapeutic value for some lesions. [0003] CT-guided percutaneous lung biopsy was first reported in 1976, and currently plays a key role in the diagnosis of peripheral lesions, especially peripheral pulmonary nodules. Although there are many new methods of CT-guided puncture, such as real-time...
