The benefits of Endoscope insertion tube assembly include its ability to reduce complication rates and minimize insufflation. This is possible due to the two types of resins and water that are used in its assembly. This method also permits biopsies. Let us examine these features in more detail. Read on to find out how it works. The benefits of Endoscope insertion tube assembly
Endoscope insertion tube assembly prevents insufflation
The insertion tube assembly contains the imaging device, deflection cable, and objective lens. The tube is flexible and has four angulation wires attached at four points along its length. Pulling on one of the wires will cause the tube to curl in the opposite direction. The other two wires can deflect down and to the left, respectively. Once the lens assembly is in place, the device is fixed in the heat exchanger with adhesive.
The air supply system of an endoscope includes an air source and a venting system. The gas is withdrawn from proximal gas ports as the endoscope is inserted into a lumen. The valves prevent insufflation. The insufflation valve must be triggered by passing the finger over the opening of the valve. The valves on the endoscope insertion tube assembly must be manipulated carefully to avoid insufflation.
Gas supply to the colon is a key component of conventional endoscopic systems. When the colon is empty, it collapses and must be inflated in order to allow clear visualization of the contents inside. Insufflation ensures that the gas pressure inside the colon remains constant for a clear field of view. The gas source is connected to the proximal endoscope 18 via a free space or dedicated lumen.
It uses water
A typical endoscopic air, water, and suction system is shown in Fig. 3.9. A light source supplies air in the form of a small air pump, which feeds the air through a water/air valve on the distal tip of the instrument. The air exits through a vent hole on the top of the air/water valve. Water can also be fed across the objective lens to clean it.
The proximal end of the insertion tube is made of hard resin. It is generally 50 to 160 cm long, and is stiff to prevent the loop from reforming when inserted into a straight colon. It also has a spring-loaded elastomer mechanism that allows it to flex and stretch as it is inserted. This enables the endoscope to be maneuvered more easily through the body.
The bending section of the endoscope is used to manipulate the distal tip. It contains four angulation wires that run along the insertion tube and are attached to the tip in four locations. When the user pulls on the wire at the 12 o’clock position, the bending section will curled up. The same wire will curl up when it is pulled at the three o’clock position. The other two wires allow the bending section to bend to the right and left, respectively.
It uses two types of resins
The flexible endoscope insertion tube consists of a basic tubular core structure with a polymer outer meshwork tube bonded to it. A resin tube is integrally bonded to the tubular core so as to maintain the inherent compressive pre-stress of the tube. The endoscope tube’s flexibility varies step-wise from one end to the other. Resin tube lengths are configured by integrally bonding two or more resin tube sections made of different hardnesses and resin materials.
The resin material that is used to manufacture the channel tube of the endoscope insertion tube assembly is manufactured in a specialized manner. The endoscope insertion tube assembly can include a channel tube made of two different types of resins. The channel tube 26 can be produced by joining two tubes. After forming the channel tube, it can be processed to a desired length.
The distal end of the insertion tube is made of two types of resins, one of which is significantly harder than the other. The soft resin is inserted first through an insertion port and replaced with the hard resin in a transition zone near the middle of the tube. Once inserted into the insertion port, the treatment instrument protrudes through the endoscope and performs the desired treatment.
It allows for biopsies
An Endoscope Insertion Tube Assembly allows the physician to perform procedures such as biopsies. These instruments are made from a flexible tubing that contains an air, water, and suction system. The air, water, and suction systems connect to a light source that is attached to the cart. The air pump inside the water bottle presses air into the insertion tube and out of a vent hole in the cap of the bottle. The water is then forced into the endoscope through a channel on the distal tip of the instrument.
The bending section of an Endoscope can be adjusted by the endoscopist to allow them to get an accurate view of the internal structures of the body. There are four angulation wires running along the length of the insertion tube. These wires are attached to the tip of the endoscope at various points. Pulling the wire at three o’clock will cause the tip to curve up. Pulling on the other wires will cause the tip to deflect to the right or left.
EUS can also be used to diagnose diseases of the pancreas and bile duct, as well as the stage of cancer. By using this device, physicians can obtain tissue samples from gastrointestinal tumors and lymph nodes. The Endoscope Insertion Tube Assembly is also an important part of the surgical process. It allows the physician to perform a biopsy by inserting a tiny needle through the endoscope.
It is portable
The portable Endoscope 100 has a detachable shaft assembly 102 a working channel 1102 for facilitating various medical procedures. The working channel turret 104 is attached to the shaft assembly 102 a and facilitates various medical procedures such as lavage, aspiration, manipulation, and a variety of other operations. The working channel turret 104 also includes a post subassembly 1202 for fixing the shaft.
The portable Endoscope 100 includes an operator control section assembly 101 and multiple shaft assemblies, each configured for a specific endoscopic purpose. Each shaft assembly comprises an elongated body and a locally bendable distal end. A detachable operator control section assembly 101 senses the pull requirements of the flexible insertion shafts 105 and automatically adjusts the leverage and gearing. The detachable operator control section assembly 101 is controlled by a thumb motion by the operator.
The Endoscope 100 is also equipped with a detachable operator control section assembly 101 and a detachable light stick 801 to facilitate the imaging process. These two components, together with the optical imaging system 1102, make up a portable Endoscope 100. These portable endoscopes are designed to be portable and allow the clinician to move freely without the need to reposition the Endoscope.
It is disposable
An Endoscope Insertion Tube Assembly is a sterile, disposable part that connects an endoscope to a camera. After use, the disposable channel is removed and disposed of. The device also features a magnetic attachment or very strong elastic band for attachment. The distal end of the endoscope protrudes out of the dispenser and the non-inflatable portion of the sleeve is folded. The insertion tube is visible at the rear.
The Endoscope Insertion Tube Assembly is made of a polymer material that is biocompatible, water-tight, and atraumatic. The plastic is typically marked with numbers that indicate the depth of insertion. It’s also easy to reuse. A typical endoscope has a life expectancy of 10 uses. With this technology, it’s possible to minimize medical costs and improve patient safety.
The multilumen tube and retaining sleeve are both disposable. The retaining sleeve allows for easy removal of the endoscope after use, and the multilumen tubing and camera head are disposed of after use. The entire set is disposable, enabling patients to save on hospital costs. When the time comes to replace the device, the disposable Endoscope Insertion Tube Assembly can be reused.
An endoscope using the invention comprises a flexible sleeve and an insertion tube. The distal endoscope is coupled to a dispenser for antifriction fluid. This fluid reduces friction during the displacement of the insertion tube. Moreover, the sleeve is completely disposable. The invention also provides a method for sterilizing the disposable Endoscope Insertion Tube Assembly and its associated components.
