1. A detachable stylet assembly adapted for endotracheal intubation of a patient comprising:
(a) an elongated tube as a stylet for the intubation defining: a longitudinal axis, a proximal end detachably mounting the stylet to a hand grip, and a distal end for entering the trachea of the patient; wherein the tube comprises an articulation section adjacent the distal end adapted to curve into the trachea upon actuation; (b) an actuator housing mounted on and adjacent to the proximal end of the tube comprising an actuating assembly having connection means for engaging the hand grip; (c) a control wire mounted within the actuator housing and connected to the actuating assembly, wherein the control wire extends through the tube to the distal end of the tube and is adapted to curve the articulation section upon actuation, wherein the actuator housing comprises an electrical connection mounted on the actuator housing and adapted to be coupled to a mating electrical connection port in the hand grip, wherein the electrical connection port is coupled to a camera mounted adjacent the distal end of the elongated tube, wherein the hand grip comprises: (i) a grip housing; (ii) a trigger as a pivotable lever extending from the housing towards the distal end of the elongated tube and away and nonparallel with respect to the longitudinal axis; and (iii) a stationary handle as a base for squeezing the trigger towards the handle when engaged, the base extending towards the distal end and parallel with the elongated tube, wherein the connection means is a stem protruding outside the actuator housing and connecting to a hole defined on an actuator linkage mounted in a housing of the hand grip which is engaged with the trigger; and wherein the stem extends perpendicular with respect to the longitudinal axis out of the actuator housing, and wherein the lever engages the actuating assembly through the connection means and is adapted to cause the control wire to curve when the trigger is squeezed. |
