The actuator may comprise a button including a lumen extending through the button; an interior body coupled to the button, wherein a first channel of the interior body is fluidically connected to the lumen; and an exterior body coupled to the handle body, wherein the interior body is received by the exterior body. The actuator is operable at a plurality of different positions along a circumference of the handle body, and the actuator is configured to: supply air to the medical device when a user covers the lumen; and/or supply liquid to the medical device when a user presses the button.

Abstract: A medical device comprising, a handle body, a flexible shaft coupled to a distal end of the handle body, a distal tip coupled to a distal end of the shaft and including a movable element, and an actuator coupled to the handle body and configured, upon actuation, to move the movable element, wherein the actuator includes a first contact element having outer contact surfaces each configured for contact by a finger of a user, each of the outer contact surfaces being at least one of angled and recessed relative to the other outer contact surfaces to provide a plurality of positions of contact between the finger and the actuator.

Abstract: A medical system includes a medical device and an end cap. The medical device includes a handle, including an actuation device, and a shaft extending from the handle. A distal end of the shaft includes a tab, and the tab is movable based on movement of the actuation device. The end cap includes a modular camera assembly. The modular camera assembly includes a camera, a support, an arm, and a cavity. The tab is coupleable to the modular camera assembly via the cavity, and movement of the tab controls a position of the support and the camera.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to medical devices and systems with control knobs designed for improved usability and ergonomics. For example, the control knobs of the present disclosure may include surface features for improved gripping, surface features for improved perception of medical device orientation within a patient and/or knobs dimensioned for improved thumb reach and reduced torque.

Abstract: A handle of a medical device may comprise an actuator; a lock movable relative to the actuator and having a feature movable relative to the actuator; and a rack having plurality of teeth separated from one another by a plurality of gaps. The lock may be configured to move the feature from (a) a first configuration, in which the feature is disposed in the gap, between two of the plurality of teeth, such that the two teeth inhibit the actuator from rotating; to (b) a second configuration, in which the feature is disposed outside of the gap, such that the actuator is rotatable. In the second configuration, the teeth may be disposed between the feature and the actuator.

Abstract: A medical device includes a handle, a shaft extending from the handle, and an articulation member integral with or attached to a distal end of the shaft. The articulation member includes a first portion coupled to a second portion, the second portion is receivable in a slot defined by the first portion, and the handle is coupled to each of the first portion and the second portion and to articulate the first portion independently of articulating the second portion.

Abstract: A medical device that includes a clamp having a body defining a channel and a fixation member that is configured to move relative to the body from an unlocked position to a locked position. The medical device includes an actuator coupled to the fixation member and configured to move the fixation member from the unlocked position to the locked position. The fixation member extends at least partially into or radially outward from the channel in response to moving from the unlocked position to the locked position.

Abstract: A medical device includes a handle with a proximal arm and a distal arm. The proximal arm and the distal arm are pivotable via a joint. The medical device also includes a tube coupled to the distal arm and a drive wire. A distal portion of the drive wire includes an expandable end effector. A portion of the drive wire is positioned within the tube, and a different portion of the drive wire extends proximally of the distal arm and is coupled to the proximal arm.

Abstract: A medical device that includes a body and an arm extending from the body and configured to receive a first device such that the first device is suspended relative to the body.
