Endoscope System

Overview

A flexible video endoscope system lets a clinician inspect and treat the interior of a hollow organ through a natural orifice. A slender steerable scope carries a camera chip and illumination to the distal tip; a tower of supporting equipment processes the image, supplies light and irrigation, and displays live video. The same instrument channel passes biopsy forceps, snares, and other tools to the field.

The instrument itself is the Flexible Video Endoscope, a flexible insertion shaft with a four-way articulating bending section, an ergonomic control body with steering knobs and valves, and an umbilical cord back to the tower. At its tip sits a CMOS imager behind an objective lens, distal LED or fiber illumination, and a lens-wash nozzle. Internal lumens run a working/suction channel alongside air and water lines for insufflation and cleaning.

How it works

The imager's signal travels up the scope to the Video Processor, which drives the sensor, processes the raw image, applies enhancement modes such as narrow-band imaging, and renders live video. Illumination comes from the Light Source, a high-output LED illuminator that couples regulated light into the scope's light guide under automatic brightness feedback so exposure stays even as the camera moves. Processed video is shown on the Surgical Monitor, a medical-grade display on an articulating arm.

Insufflation and lens washing are fed from the Water Bottle Unit, a pressurized sterile-water unit whose pump drives air and water through the scope's channels. The clinician captures images and triggers accessory functions hands-free with the Foot Pedal. All of it stacks on the Tower Cart, a mobile tower on locking casters with a medical isolation transformer powering the components. After each case the scope is leak-tested and reprocessed by high-level disinfection.
