Precision in Neurosurgery: An Introduction to Stereotaxic Instruments
Stereotaxic Instruments Devices called stereotaxics are used to precisely target particular brain regions. They offer a three-dimensional coordinate system that can be used to manipulate small targets inside the brain for a variety of applications, including device implantation, lesion formation, and biopsies. The instruments are made up of a stereotaxic frame that fixes the head in place and a number of supplementary items that help with targeting and navigation. Evolution of Stereotaxic Technology The development of Stereotaxic Instruments dates back to the early 20th century. Initially, these tools were used primarily in animal research to understand brain function. The first human applications began in the mid-20th century, significantly advancing with the advent of imaging technologies like MRI and CT scans. These imaging techniques allowed for more accurate mapping and targeting, leading to safer and more effective procedures. Key Components and Functionality The pr...
