Anatomy of Flexible Endoscopes

Introduction

Flexible endoscopes are special tools designed to help physicians look inside the body. An endoscope is a long, thin, flexible tube with a light and a camera on one end. Doctors can maneuver it through natural body openings, such as the mouth or nose, through the organs, for example, into the stomach, lungs, or intestines. This tool has become very important in medical fields such as gastroenterology, which deals with stomach and intestinal issues, and pulmonology, which deals with lung problems.

In this paper, we shall describe the different parts of a flexible endoscope and understand the specialized work of each. Knowledge of such parts would assist an individual in appreciating how the detail and involvement of every single part make up the whole and, hence, their importance in the diagnosis and treatment of certain health conditions.

Let’s examine each of these elements of a flexible endoscope and see how they work together to give physicians a clear vision of our bodies and better serve their patients.

What are the Parts of a Flexible Endoscope?

A flexible endoscope is divided into three main sections. Each has its purpose, which must be well known to understand how doctors will use this device to examine the inside of the patient’s body.

Connector Section (Umbilical)

It is the section of the endoscope, which is the lifeline. The endoscope is connected to those external devices considered essential for its operations. The umbilical is so-called by some people because it offers the necessary links that would sustain the operations of the endoscope, which would otherwise be sustained by an umbilical cord.

Control Body

It is known as the brain of the endoscope. The control body is at the top of the handle, where doctors manipulate the endoscope. There are controls to steer the tip of the endoscope to get better views, and it contains some of the functions for the use of the air and water channels, and the suction features help in the examination and treatment process.

Insertion Tube

 It refers to the long and flexible part of the endoscope that doctors carefully insert into the patient’s body. It has marks to guide the length of insertion tube. It is of paramount importance, as it carries a camera and light, thus enabling doctors to visualize and record images of internal body parts under examination.

What is the Control Body of a Flexible Endoscope?

The control body is usually the most important part of a flexible endoscope; it is normally described as the “head” of the endoscope. It contains all the control mechanisms and devices that fully operationalize the endoscope during medical procedures.

The light guide tube is at the center of the control body; very importantly, the control body connects to the light guide connector, which is further plugged into the external light source. This is of great importance because it sheds light on the internal parts of the body that are being checked, hence offering a clear view of these parts to the doctor.

Connections within the control body for various functions, which play an important role in an endoscopy, are as follows:

Suction

Assists in removing any fluids or debris from the viewing area to maintain clarity.

CO2 and Air/Water Bottle

It is used to insufflate organs to achieve better visualization and to clean the camera lens so the images obtained are clear.

Light Fiber Bundle and Electrical Contacts

Fiber-optic bundle and electrical contacts to conduct light and electrical signals for imaging and operation of the endoscope.

The control body is designed to be user-friendly and allow the doctor to operate the endoscope promptly and dexterously, thereby enhancing the safety and effectiveness of the procedure.

What is the Insertion Tube of a Flexible Endoscope?

The insertion tube is a component within the flexible endoscope in direct contact with the patient’s body. Clinicians pass this part through body orifices such as the mouth or nose to access organs.

The graduated lines on the tube marked with graduations are a reference for physicians to know the depth of insertion of the endoscope. This is important for the safe and effective conduct of the procedure without any unnecessary insertion deep inside.

The bending section is located at the distal end of the insertion tube. It is very flexible because it is sheathed with soft rubber, enabling the endoscope to navigate through tight or curved spaces inside the body. This is important to make movement easier and less uncomfortable and to avoid the impairment of tissues of internal parts during the procedure.

Running inside the outer sheath of the insertion tube, a metal coil impregnated with a woven wire mesh further adds to its structural rigidity. This protects sensitive internal parts of the endoscope, such as fiber optics and channels, from damage in deflection and ensures a robust, long-lasting, and reliable design against repeated use.

What is the Umbilical Cord of a Flexible Endoscope?

The umbilical cord of a flexible endoscope, which can sometimes also be referred to as the “flexible tube,” houses all necessary channels and connections for the endoscope to perform and function inside a procedure.

This umbilical cord is attached to the control body. It ends with the PVE connector, the other vital point of connection that allows the processor unit to connect with the endoscope, the primary device regulating endoscope functions and processing visual information received in the process.

Within the umbilical cord, there are several vital ports and channels:

Air/Water Port

The port allows air and water to pass through, which inflates organs for better visualization and cleans the lens for clean images.

Suction Port

It lets fluids and debris out from the examination area to give clear visibility.

Leak Test Port

It is important for testing the integrity of the endoscope to determine whether it is sealed or leaky and thus fit for use.

Light Guide Tubes and Electrical Contacts

Transmit the light and electrical signals that are required in the operation of the camera or other functionalities.

The design of the umbilical cord should ensure the seamless integration of the endoscope’s design and functionality with the supporting systems, aiming to improve efficiency and safety in performing medical procedures.

What is the Channel Section of a Flexible Endoscope?

Air/water channel

A flexible endoscope has a channel section, which is often compared to the “plumbing” network within the scope. It is the most critical area in terms of performing various functions in an endoscopic procedure, typically related to the handling of fluids and air.

The following are two basic types of channels found in this section:

Air Channel

This channel allows air to pass through the endoscope. It is mainly used to inflate body cavities such as the stomach or intestines, allowing the physician to have a much better and bigger view of the structures.

Water Channel

The main purpose of the water channel is to provide the continuous feeding of water. It is a medium through which water is used to clean the lens of the camera, mounted at the tip of the endoscope, to make sure the images are clear all along. It can also irrigate some parts of the body in an effort to make them visible.

Additionally, there is a Biopsy/Suction Channel.

A channel runs from the suction port in the light guide connector through the control body and finally down the insertion tube. The biopsy/suction channel allows the instrument to aspirate fluids and debris and introduce instruments for biopsies, which involves removing small tissue samples for examination.

Each of the channels is designed to operate under the confined space of the endoscope, ensuring vital support for the overall success and safety of the procedure.
