[The development of three dimensional video microscope system for clinical application in neurosurgery]

Area of Science:

• Neurosurgery
• Surgical Technology
• Medical Imaging

Context:

• Traditional surgical microscopes in neurosurgery demand prolonged, static postures, causing significant physical and ocular strain for surgeons and assistants.
• The need for advanced surgical techniques in complex neurosurgical procedures often necessitates extended operative times, exacerbating ergonomic challenges.
• Existing microscopic visualization methods limit the collaborative viewing and ergonomic flexibility for the surgical team.

Purpose:

• To develop and clinically apply a three-dimensional (3D) video microscope system for neurosurgery.
• To overcome the ergonomic limitations and physical fatigue associated with conventional surgical microscopes.
• To enhance the surgical experience by allowing procedures to be performed via a video monitor.

Summary:

• A 3D video microscope system utilizing two binocular cameras was developed and applied in 42 neurosurgical cases.
• Surgeons and assistants viewed stereoscopic images on a monitor, eliminating the need to look through eyepieces and allowing for more flexible postures.
• The system provided a separate monitor for the assistant and enabled shared 3D visualization for the entire surgical team, including trainees.

Impact:

• Reduced physical fatigue and ocular strain for surgeons and assistants during long neurosurgical procedures.
• Improved ergonomic conditions and greater postural freedom during microsurgery.
• Facilitated a better educational environment by allowing multiple observers to view the 3D surgical field simultaneously.
