Medical system

Abstract

The embodiment of the invention provides a medical system. The medical system comprises an operation table, a magnetic navigation device, a medical imaging device and an optical positioning device, the magnetic navigation device is used for navigating a positioning medical tool to a focus area on a medical path according to the medical path; the optical positioning device comprises an imaging module and at least three first markers arranged on the medical imaging device, and the optical positioning device is used for obtaining the position of the medical imaging device relative to the imaging module according to imaging of the imaging module on the at least three first markers; the medical imaging device is used for moving according to the position of the medical imaging device relative to the imaging module to scan the head end area of the positioning medical tool to obtain an image, and reconstructing a two-dimensional image and / or a three-dimensional model of the head end area of the positioning medical tool. To confirm a surrounding condition of the localized medical tool and whether the localized medical tool reaches a correct location.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a medical system. Background technique [0002] The diagnosis and treatment of pulmonary nodules have become more and more important for the early detection and treatment of lung cancer. The more advanced diagnosis and treatment method is that the magnetic navigation equipment plans the medical path from the natural airway to the lesion location through medical images, and navigates the medical tools to the lesion location along this medical path, and then treats the lesion accordingly. [0003] However, the above lesion positions are only the lesion positions on the medical path planned by the magnetic navigation equipment through the previous medical images, accompanied by the patient's respiratory movement and possible deformation due to the soft tissue of the organ, which requires relatively complex coordination. The actual shape and position of the trachea may not exactly ...

Problems solved by technology

[0003] However, the above lesion positions are only the lesion positions on the medical path planned by the magnetic navigation equipment through the previous medical images, accompanied by the patient's respiratory movement and possible deformation due to the soft tissue of the organ, which requires relatively complex coordination. The actual shape and position of the trachea may not exactly match the medical path, and the actual lesion position may deviate from the planned target position. In the process of navigating medical tools, the previous medical images are only used as auxiliary judgments. , will also lead to poor accuracy and effective navigation efficiency of magnetic navigation
