The introducer sheath (100) includes multiple radii of curvatures, guiding the endotracheal tube (115) of different diameters through the patient airway. Typically, the endoscope (120) is positioned inside the endotracheal tube (115) and subsequently the endotracheal tube (115) along with the endoscope (120) is mounted into the introducer sheath (100) via the lateral aperture. Furthermore, the endotracheal tube (115) with the endoscope (120) is a medical device used in airway management during the medical procedure. The endotracheal tube (115) is a flexible tube inserted into the trachea to maintain an open airway during surgery or critical care. The endoscope (120) includes a camera (not shown in FIG. 1) attached to an end of the endotracheal tube (115). The camera provides a real-time visualization of the trachea and surrounding structures, guiding the placement of the endotracheal tube (115) more accurately and reducing risk of complications like accidental insertion. Repeating, hence deleted.

[0027] Further, the distal end (130) of the introducer sheath (100) is adapted to facilitate positioning of the endotracheal tube (115) with the endoscope (120) inside the trachea. The distal end (130) is extended outward thereby creating a protrusion to cover the endoscope (120) like a hood. The protrusion at the distal end (130) is flattened to provide a smooth surface for insertion of the endotracheal tube (115). Typically, the protrusion serves as a protective cover for the endoscope, shielding the endoscope (120) from contact with surrounding tissues and structures during insertion into the trachea, preventing damage and ensuring the endoscope (120) functionality during the medical procedure.

[0028] Furthermore, the introducer sheath (100) includes a handle (135) positioned at the proximal end (110) at a predefined angle to provide support for a user during a medical procedure. The handle (135) facilitates passage of the introducer sheath (100) along with the endotracheal tube (115) and the endoscope (120) via the oral cavity of the patient (125) into the trachea. Thereby exerting downward pressure on oropharynx and facilitating placement of the introducer sheath (100) along with the endotracheal tube (115) and the endoscope (120) in larynx in between vocal cords and oriented towards the trachea. The handle (135) is flat and textured with a dotted surface for providing a firm grip to the user. Typically, the handle (135) is affixed to the distal end (130) at an angle ranging from 10 degrees to 20 degrees to a tangent of axis of the handle (135) and the handle (135) of the introducer sheath (100) is ergonomically designed to enable the user to grip the introducer sheath (100) by a thumb on one side, and an index, middle, and ring fingers on other side thereby facilitating secure handling of the introducer sheath (100) during insertion of the endotracheal tube (115).

[0029] Moreover, the introducer sheath (100) includes an aperture (140) positioned on one side of the introducer sheath, and in between the proximal end (110) and the distal end (130) of the introducer sheath (100). The aperture (140) is adapted to remove the introducer sheath (100) via lateral aperture after placement of the endotracheal tube (115) with the endoscope (120) in the trachea of the patient (125) upon visualizing the trachea and carina by utilizing the endoscope. Typically, the lateral aperture is designed for safe and efficient introducer sheath (100) removal without compromising the endotracheal tube (115) placement or disrupting the patient's airway.

[0030] In an example, consider a scenario, user ‘X’ performs endotracheal intubation on a user ‘Y’ or the patient. The user ‘X’ selects the introducer sheath (100) to assist in guiding the endotracheal tube (115) and endoscope (120) into the patient's trachea. The proximal end (110) of the introducer sheath (100) is wide enough to accommodate both the endotracheal tube (115) and the endoscope, allowing for simultaneous insertion via the patient's oral cavity. As the user ‘X’ navigates the introducer sheath (100) into the trachea of the patient, the extended outward protrusion at the distal end (130) acts as a hood, covering the endoscope (120) and providing a smooth surface for the insertion of the endotracheal tube (115). The handle (135) positioned at the proximal end (110) provides support and stability, facilitating passage through the oropharynx and ensuring precise placement between the vocal cords. Once the endotracheal tube (115) and endoscope (120) are correctly positioned in the trachea. The user ‘X’ utilizes the endoscope (120) to visualize the trachea and carina in the patient. Upon confirming proper placement, the user ‘X’ identifies the aperture (140) positioned on one side of the introducer sheath (100). Further, the aperture (140) allows for safe removal of the introducer sheath (100), minimizing disturbance to the patient’s airway.
