biopsy channel endoscope

To use a properly, technicians must learn how to grip it. The most common grip is a two-finger grip with the thumb under the hand piece. The fourth and fifth fingers are placed around the top of the endoscope, and the index and middle finger are used for valve control. The thumb is also used to manipulate the knobs or other features of the instrument. The endoscope is usually held by the right hand. The right hand can also be held in three fingers.

Double-balloon enteroscope

A new endoscopic technique called double-balloon endoscopy (DBE) allows for comprehensive visualization and therapeutic interventions in the small intestine. While there is still some debate over the safety and efficacy of DBE, it has demonstrated high patient tolerance. A recent study sought to determine the indications and safety of the procedure in patients with suspected or documented gastrointestinal tract disorders. Here, the authors outline the basic features of DBE and discuss their potential benefits.

Single-balloon enteroscopy, has low complications. The distal tip of the scope is attached to a single balloon on the overtube, which fixes the endoscope while it is advanced into the small bowel. This technique allows the endoscope to be inserted as deep into the small intestine as possible without over-extensive angulation.

Sonde endoscope

The use of a Sonde endoscope for biopsy channel is often the most effective way of obtaining tissue samples from the stomach. A biopsy is a valuable tool to diagnose the health of the stomach. The biopsy procedure is performed using a thin endoscope that can be attached to the endoscope’s biopsy channel. In addition to its diagnostic value, a Sonde endoscope can help identify bacterial infections. A used endoscope should be inspected for damage and leakage. Broken fibers, which make the images visible, are visible as black dots on the endoscope’s screen. While some broken fibers may be acceptable, too many will interfere with visualization.

The control section of the endoscope has several openings, including a light guide, air-water outlet, and an instrument channel for suction and biopsy forceps. Large-diameter therapeutic instruments may also have an auxiliary water channel or a second suction/instrument channel. The flexible part of the endoscope is the “working length” of the instrument. A hood or friction-fit adaptor may be added to the endoscope for esophageal ligations and meat impactions.

Oblique-viewing endoscope

An oblique-viewing is an oblique-viewing device that rotates to allow for viewing in different angles. This allows for more precise anatomy interpretation and is especially useful for advanced laparoscopic procedures. An optimal viewing angle is obtained when the cylinder rotates at an angle perpendicular to the Target plane. This is an ideal viewing angle for a bimanual endoscope, because inequalities in azimuth angles reduce task efficiency.

The working channel of an oblique-viewing endoscope is designed for the use of ultrasound. The ultrasound transducer is located adjacent to the working channel and displays a forward-viewing image. The tip of the endoscope is designed to allow the use of large-calibre needles and improve mechanical force to the accessory’s tip. Oblique-viewing biopsy channel endoscopes are an improvement over standard therapeutic EUS scopes.
