endoscope insertion tube

When choosing an endoscope, it is important to choose a quality insertion tube with an optimal working channel bore. There are three important factors to consider when selecting an insertion tube. These factors are flexibility, durability, and rotation angle. This article will discuss these factors and help you choose the best https://www.smarttechmed.com/. Read on to find out more! (*) Listed below are some other tips to choosing the right insertion tube for your needs.

Working channel bore 220

In order to avoid the risks of a compromised device, the working channel bore 220 of the https://www.smarttechmed.com/product-category/endoscope-replacement-parts/video-heads-buttons/ is designed to have a lower resistance to laser light energy. As such, it is less likely to break under normal wear conditions. Its protective sleeve is also shaped to fit the working channel. The distal end plate 200 is preferably disposed on a coaxial axis with the working channel bore 220.


The flexible endoscope insertion tube of the present invention provides uniform flexibility, chemical, heat and weather resistance. Embodiments of the invention may vary. In addition to the claims set forth below, the present invention also provides a method and apparatus for achieving these properties. This disclosure relates to Japanese Patent Application No. 11-353541, filed on Dec. 13, 1999. The bending section of the insertion tube can be manipulated by pulling a wire at various points along the insertion tube. The wires that control its deflection are attached at the twelve-o-clock and three-o-clock positions. Pulling on the other wires causes deflection of the tip.


The durability of an endoscope insertion tube depends on the material used to make it. A polymer layer is used to create the insertion tube’s outer cover. The outer cover is water-tight and biocompatible, and it has numbers on it to indicate how far the instrument should be inserted. The material is also usually coated with a layer of PVC to ensure patient safety. The endoscope insertion tube can be either hard or soft, depending on its application.

Rotation angle

The endoscope insertion tube’s shaft rotates to the left. This conventional style is a more natural way to manipulate the endoscope insertion tube. However, it has a major drawback – the shaft is more difficult to rotate fully leftward. While this is acceptable for screening endoscopy, it may be problematic during a procedure when the examiner’s posture is strained.


In accordance with the principles of the invention, a Liner for endoscope insertion tube includes a longitudinal slot 36 and a pair of contiguous C-profile channels. The channels 88 and 90 communicate with the ambient environment through a mutual dual-lobe distal end opening 92 and with one or more proximal end apertures. The longitudinal slots are defined by opposing longitudinal edges.
