Nano-Cameras Packaged Individually as Part of Surgical System

When I read about the Medigus 1.2mm camera, I thought about Richard Feynman’s lecture, “There's Plenty of Room at the Bottom," at an American Physical Society meeting at Caltech on December 29, 1959, considered to be a seminal event in the history of nanotechnology.

Medigus is a medical device company focused on innovative endoscopic procedures and devices. Medigus developed an entire endoscopic system for treatment of GERD (Gastro Esophageal Reflux Disease). The endoscopic system combines a miniaturized video camera, a surgical stapler, and ultrasonic sights for alignment in a single instrument. Shifting the GERD treatment from surgery to an endoluminal procedure, without opening the abdominal cavity, is a revolutionary approach.

The most interesting element in the system is the world’s smallest video camera. Medigus's 1.2mm camera combines a unique proprietary CMOS sensor technology and a state-of-the-art custom optic composed of five lenses objective from 0.5mm/lens. The camera's CMOS sensor package diameter is 0.7mm X 0.7mm, with pixel size of 2.2µm X 2.2µm. The sensor obtains 49,200 effective elements (220 X 224px) to deliver an extraordinary image performance for its size.

Using different lenses, the camera's field of view (FOV) can be modified between 100° and 140°, to produce working distance of 1mm to 50mm in order to meet the applicative requirements.

As far as the packaging is concerned, each and every camera is being packed individually. The camera has been tested successfully at Medigus for high-level disinfection using CIDEX OPA. The camera has been also tested successfully at Medigus for sterilization using EtO.

This is a design marvel, which will enhance clinical workflow and will significantly reduce patient recovery and hospitalization time. What do you think about it?
