The Curved Section Assembly is a critical component of the Endoscope, which is used to look at organs, including the bowel, that are difficult to access. This assembly uses a pair of cables to control bending of the endoscope. One cable wraps around a wheel on the endoscope’s proximal end, passing through a hole in the link wall on the inside of the bending arc. The second cable straightens the section.
J-turn
A curved endoscope is a common surgical tool used during open surgery. Its curved section allows physicians to view small organs without having to use a blunt instrument. The endoscope’s flexible section is made to flex to accommodate the curvature of an organ while relaying wire tension to the articulating module. Its curved design allows the instrument to be positioned in various positions and is highly responsive to movements.
The J-turn endoscope has a curved section. This section can be used to visualize a diverticulum or other resected obstruction. When inserted in the descending part of the duodenum, the angled endoscope can observe the esophageal web. An angled endoscope can be advanced through the descending portion of the esophagus with upward deflection of the distal tip. This type of endoscope is designed for the smoothest insertion possible to avoid bleeding marks.
An additional advantage of the proposed endoscope is its mobility. The device can be operated outside of a hospital using a smartphone. The battery-based unit can also be used in regions with limited health services. In these cases, the endoscope can be used by a single operator. The battery-powered system can also maintain the system if power fails. Lastly, the device’s mobility makes it suitable for use outside of well-developed regions.
An arrow-marked part in the curved section may be defective. A defective one may cause the curved section to move backwards. The mainframe of the J-turn endoscope has numerous buttons. A dotted circle is the light source button. If the light source is turned off, the screen may be invisible and the scope cannot be advanced. In addition, without the correct light source, endoscopy cannot be performed.
A curved section should be used when entering the pyloric ring. This can be difficult for beginning endoscopists because the scope may not be visible. However, the curved section of the endoscope will allow the doctor to look into the pyloric ring and duodenum. Once the endoscope reaches the pyloric ring, it will be visible in the curved section.
U-turn
An Endoscope Curved Section Assembly (ECSA) includes a control handle, a bending portion, and a rigid tip portion. The bending portion is flexible in the longitudinal and torsional directions and is connected to the control handle by a plurality of Bowden cables. These cables are arranged partly within the control handle. As the user turns the control handle, the bending portion bends.
A second control wire extends backward from the lever member. It connects to a pillar 42 in the housing. The pillar acts as a pulley. This enables the insertion portion to rotate. This is a preferred approach when the curved section assembly must be turned during an EGD. Once positioned, the curved section assembly can be rotated as needed.
The U-turn maneuver allows for a good view of the greater curvature of the gastric body. It also enables detailed observation of the cardia and fundus. Because the scope is angled upward, the fundus and anterior abdominal walls can be observed in the opposite directions. Once this maneuver is performed, a sharper J-turn may be achieved. The pyloric ring will be visible at the front of the antrum.
Those skilled in the art will recognize that endoscopes with the above-mentioned features are well known. Therefore, further details are not required in order to understand the present invention. The main invention disclosed in the current application relates to a mechanism of a control handle that controls bending of the curved section. If this mechanism is improved, the U-turn can be performed with greater ease.
Using the angled tip of the endoscope in the GEJ and esophagus helps in observing the esophageal web. For this reason, the distal tip of the endoscope should not be deflected too much when advancing the scope. Moreover, the examiner should not over-push the endoscope, and should rotate the endoscope with a slight rotation to put the center of the esophageal lumen in the center of the screen.
Positioning of the endoscope on the screen
The X-ray imaging system is a highly versatile tool for imaging internal organs, including the brain and other tissues. The curved section of the endoscope is positioned on the screen to provide a clear image of the inner structure of the patient’s brain. Various techniques are used to position the endoscope on the screen. These methods are based on the inverse cosine transformation.
Generally, the curved section of the endoscope is placed at an angle that is at least one unit higher than the x-ray image. The angle of the screen will be determined by the distance between the curved section and the object being studied. The angle of the curved section will determine the amount of movement required for the instrument to move. The curved section assembly must be in a position in which it is oriented to the patient’s anatomy.
The light source device 3 comprises a lamp that produces illumination light. The light guide 21 is inserted through the universal code 11 and control potion 10 through the insertion portion 9. The curved section 7 is controlled by a curving control knob. The aperture of the light guide must be aligned with the screen. Once the curved section 7 is aligned with the screen, the device is ready to perform observation.
The bending part is a complex piece of equipment that bends the endoscope in various directions. The curved section of the endoscope is designed to have an objective lens that focuses the miniature image of the GI mucosa onto a CCD image sensor. The sensor is securely sealed to prevent fluid from entering the system. During insertion, the bending part is controlled by turning control knobs in the hand control part.
The bending section of the endoscope is the tip of the instrument used for manipulating the organs. The bending section is comprised of several oddly shaped metal rings that are connected by freely-moving joints. These joints are made with pivot pins that are offset 90 degrees from one another. One set of pivots allows the bending section to curl upwards while the second set of pivots is used for curving the tip in the right and left directions.
