NeuroMainPageImageComputer Assisted Neurosurgery: Precision Where You Need it Most

It goes without saying, precision is vitally important when it comes to brain surgery.  For this reason, many neurosurgeons consider computer assisted surgery (CAS) technology standard equipment in their operating rooms.  It tracks the movement of surgical instruments and  provides the exact position of them in relation to the patient’s brain anatomy in real time.  CAS also helps guide surgeons to their surgical targets with pinpoint accuracy, while minimizing trauma to adjacent healthy tissue and potentially leading to better overall outcomes.

Stryker’s computer assisted surgery technology consists of 1.) and infrared navigation camera, 2.) Smart Instruments with light-emitting diode (LED) technology and 3.) a computer with specialized surgical navigation software.

Computer assisted neurosurgery begins with the patient undergoing a CT and/or MRI scan, showing the brain anatomy.  These scans are then loaded into the computer and the navigation software creates a virtual 3-D model of the patient’s head.  In the operating room during a process known as patient registration, the surgeon uses a Smart Instrument and an infrared sensor attached to the patient’s head to match up the patient’s actual anatomy with the virtual 3-D model.  Once patient registration is complete, the navigation camera tracks the movement of Smart Instruments and continuously feeds the location of the coordinates to the computer, displaying the exact location of the instruments on the 3-D model.

Surgeons might use this tracking technology to aid in brain tumor resections, guiding their instruments along the way.  Or, they might rely on CAS to conduct brain biopsies and shunt placements with calculated trajectory and depth. CAS also enables minimally invasive brain surgery, such as transnasal procedures where open, external incisions are not needed and surgical instruments reach the brain via the nasal sinus passages.  With these types of approaches to the brain, CAS offers an enhanced visualization of the location of surgical instruments in relation to the anatomy that cannot be seen by the naked eye.

Surgical teams may also  take advantage of the many advances navigation software provides in pre-operative planning, including: determining the location of the incision, the angle and depth of entry in to the brain, segmenting out the surgical target from surrounding healthy tissue for better visualization, and more.

 

Neurosurgery
Conditions and Procedures

CAS may be used to support neurosurgical procedures, such as:

  • Cranial biopsies
  • Craniotomies
  • Cranciectomies
  • Resection of tumors and other lesions
  • Skull base procedures

Advanced Imaging SegmentationStryker’s computer assisted surgery software incorporates advanced imaging modalities to build a virtual 3D model of the patient’s brain. This helps guide neurosurgeons to surgical targets and avoid critical structures during brain tumor resections, brain biopsies, and other procedures.

(Neuro) Navigation OR Set UpStryker’s surgical navigation technology consists of a computer with specialized software, an infrared navigation camera and Smart Instruments. This technology acts much like a GPS in an automobile, allowing the surgeon to track the exact position of instruments with respect to the patient’s anatomy in real time. Computer assisted surgery helps guide neurosurgeons to their surgical targets with greater precision during brain surgery.

(Neuro) Surgeons with Shunt Placement ToolNeurosurgeons may use computer assisted surgery during a ventricular shunt placement procedure. The navigation software and Smart Instruments aid the surgeon with placing the shunt catheter in the optimum location of the brain.
