Abstract
A detachable stylet assembly for endotracheal intubation of a patient is disclosed. The stylet comprises an elongated tube defining: a longitudinal axis, a proximal end for detachably mounting the stylet to a hand grip, and a distal end for entering the trachea of the patient. The tube comprises an articulation section adjacent the distal end adapted to curve into the trachea upon actuation. An actuator housing is mounted on and adjacent to the proximal end of the tube. An actuating assembly is constructed inside the actuator housing having connection means for engaging the hand grip. A control wire is mounted within the actuator housing and connected to the actuating assembly. The control wire extends through the tube to the distal end of the tube and is adapted to curve the articulation section upon actuation. The hand grip comprises a base handle and a trigger for manual actuation of the actuator assembly. The trigger comprises finger grooves for convenient gripping. The base handle comprises a hand stop to prevent slippage.

26. An endoscope device comprising:
-
(a) an elongated tube as a stylet defining a longitudinal axis mounted on an actuator housing and having a curvable portion at a distal end of the elongated tube comprised of;
(i) a connecter member mounted in the housing; and
(ii) a control wire attached to a proximal end that extends through the elongated tube along the longitudinal axis to the distal end of the elongated tube;(b) a hand grip comprising;
(i) a grip housing;
(ii) a base handle extending from the grip housing parallel with the longitudinal axis of the elongated tube;
(iii) a lever as a trigger extending from the grip housing and away and nonparallel with respect to the base handle;
(iv) an actuator linkage defining a connector end connected to the connector member and a lever end connected to the trigger, wherein the actuator linkage is mounted in the grip housing and is adapted to translate linearly parallel to the longitudinal axis when the trigger is squeezed towards the base handle; and
(v) a tension spring abutting against the actuator linkage for returning the actuator linkage to rest once the trigger is no longer being squeezed;wherein the trigger is adapted to be squeezed causing the trigger to pivot towards the base handle; and wherein the squeezing of the trigger translates the actuator linkage linearly away from the elongated tube which causes the connector member and the control wire to translate linearly away from the elongated tube and curve the curvable portion at the distal end of the elongated tube. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
