This invention describes a specialized camera for looking inside a patient's body during minimally invasive surgery. It uses multiple linear image sensors housed in a slender tube to capture images, which are then displayed to the surgeon in both 2D and 3D formats. A lens and reflective surface help adjust the view, and a protective cover shields the device.
Why it matters: Filed before compact, high-resolution linear image sensors and real-time 3D rendering were widely available. Modern miniaturized electronics and advanced graphics processing make this approach more feasible and cost-effective now.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
