insertion tube for endoscopy

An has a soft distal portion to protect the patient. A polymer layer provides an atraumatic and biocompatible surface, and is watertight. An is often marked with numbers to indicate its depth. It can also have an additional wire/coil sheath. In this article, we’ll discuss the advantages of each type of endoscope.

insertion tube with soft distal portion

The bending or conforming portion of an insertion tube for endoscopy has a non-circular cross-section at its outer perimeter. It may also be symmetric about its major and minor axes. A bending endoscope typically has two parts: an elongate portion and a continuous section. The bending section is a flexible tube that bends in the direction of the patient’s anatomy.

Colonoscopes with adjustable stiffness

Colonoscopes with adjustable stiffness vary in their flexibility across their length. A physician can alter the stiffness of the colonoscope by adjusting the setting on its adjustable stiffness control. For example, a rigid tube is best for upper GI tract procedures, while a flexible one is best for colonoscopic procedures. The ideal colonoscope insertion tube is flexible, elastic, and sufficiently floppy.

Colonoscopes with forward water jet connector

The ELUXEO 760 Series Colonoscopes feature a forward water jet connector that provides optimal force to clear debris and ample suction capability. These advanced colonoscopes run on the ELUXEO Endoscopic Video Imaging System for a one-step connection. The four-LED Multi-Light illumination system delivers high-quality White Light images and full HD video. The newest models are available with a forward water jet connector.

Duodenoscopes with additional wire/coil sheath

Single-use duodenoscopes with additional wire/Coil Sheaths can be advantageous for some applications. A study by Joyce et al. found that this type of device reduced the number of repositioning attempts during accessory exchange. A V-system elevator lever with an increased angle of articulation promotes the locking of a short guidewire at the elevator level, and acts as an internal wire lock. Its design is similar to traditional long wire devices at the leading end, but is unique in its external design.

Objective lens for endoscopy

The basic configuration of an insertion tube for endoscopy with an objective lens consists of a rigid, first-order optical design that encloses an oblique ray and forms an inverted image of an internal structure. The objective lens is a much smaller tube bonded to a relay lens that focuses light onto the rear face. Despite their small diameters, endoscopes are able to reach objects with a distance of just a few inches.

Sedative medication used during endoscopy

The sedative medication used during endoscopy can vary from case to case. Several options are available, and the choice is usually determined by the endoscopist’s preference and the nature of the procedure. The most commonly prescribed sedatives are benzodiazepines and midazolam, which act as anxiolytics, sedatives, and amnesics. The pharmacokinetic profile of midazolam is also superior to diazepam.
