Use the Leksell Stereotactic device for minimally invasive, functional neurosurgery. It is simple to use and provides superior imaging as well as high platform rigidity so the utmost accuracy is obtained during surgery. This device is ideal for biopsies as well due to its flexibility, accuracy, and fast operation. The Leksell Stereotactic System is versatile and includes the Leksell Multipurpose Stereotactic Arc and Leksell Coordinate Frame. It utilizes x, y, and z cartesian coordinates so it can stereotactically determine any point in 3D space. It allows full access to the intracranial areas by encompassing a surgical target within the 3D space using a center-of-arc principle. This also allows for the use of limitless entry points and trajectories. The system can be used for both therapeutic or diagnostic procedures, and supports a large ranges of applications. Its design is simple and yet sophisticated.
