Abstract: A tip light laryngoscope adapted for the trans-tissue illumination during insertion of the laryngoscope, preferably in the mucosal fold between tongue base and the epiglottis referred to as the vallecula, includes a handle and a blade with a tip at the end of the blade and a distal light source at the tip to enlighten the environment in front of the tip. The tip light laryngoscope is designed to make direct contact with the mucosa.

Abstract: An articulated segmented instrument with an elongate body in the longitudinal direction with a plurality of interconnected links. Each link has a central working channel and at least three thru holes for angulation wires to direct a distal tip segment of the instrument in a predetermined direction. Two radially opposite protrusions and two opposite receptions in the cylindrical sleeve have pivot concave contact surfaces complementary to convex pivot contact surfaces. The reception adjacent surface of the cylindrical sleeve creates an articulating angle with the protrusion adjacent surface of the cylindrical sleeve of the adjacent link through inclination of at least one of the reception adjacent surface or the protrusion adjacent surface of said adjacent link towards the body of the link or the adjacent link, respectively.

Abstract: An intubation stylet includes a shaft with a bendable end section having a tip and a camera at the tip for providing an image of a part of the environment of the tip. The stylet includes a control unit for control of the bending motion of the end section. The control unit is adapted to work under at least two operation modes. In a first of the two operation modes the bending motion of the end section is guided automatically by an orientation of the tip. In a second operation mode, the bending motion of the end section is controlled by manual control of a user without an automatically guidance. The control unit is further adapted to operate in the second operation mode when the first operation mode is inactive.
