Stereotactic framework
Stereotactic neurosurgery is a surgical method that utilizes a brain-computer interface to target the location of brain tumors. It is typically performed as an outpatient procedure. The procedure can take all day to complete, so it may be necessary to arrange for a companion to stay with you while you're at the hospital. After surgery, you may need someone to drive you home after the procedure.
The initial setup of stereotactic procedures is minimally invasive and utilizes a stereoscopic camera and computer platform with a screen. This system uses software to guide surgeons to specific locations within the brain. The surgeon places markers on the patient or on the surgical instruments to allow them to accurately localize the target structure in space. This technology is incredibly useful in difficult-to-reach locations and is increasingly becoming the standard of care in neurosurgery.
The first MR scans were obtained in 1957. The MRIs showed the exact position of the tumor and the surgeon was able to make the necessary adjustments. The next major development of stereotactic neurosurgery was the development of a device that enables the surgeon to plan the surgery in the MRI suite. This device provides the surgeon with guidance on the alignment of the targeting frame and the final tool position.
The advancement of stereotactic neurosurgery allowed doctors to map the brain in a three-dimensional coordinate system. Using this, they could precisely pinpoint an area in the brain that was causing the patient's tremor. Another minimally invasive procedure called stereotactic brain biopsy has made it possible for patients to obtain a tissue sample from the brain for diagnostic purposes. It has been used for deep-seated lesions, multiple lesions, and patients who are not good candidates for traditional surgery.
Today, stereotactic neurosurgery has been developed to perform procedures on any organ system in the body. However, it was initially restricted to brain surgery, and it is now used in other types of surgery as well. It is routinely performed to sample and locate tumor tissue in the breast. Previously, only brain surgeries used this technique. Nowadays, it is widely used to guide various surgical procedures. With these devices, a doctor can view the location of the tissue in the target organ before performing any surgery.
In addition to the use of guided probes, the development of a special tool for performing surgery has helped surgeons improve their accuracy. The technology behind the use of the technique has changed drastically since it was first used in the 1970s by Philip L. Gildenberg and Patrick J. Kelly, both physicians, developed a patented device that allows the physician to view the brain slices without a microscope. In the operating room, the surgical team can accurately see the image of the target and the procedure.
