  • Patent number: 10595928
    Abstract: A surgical instrument includes a housing supporting first and second actuators thereon, and an elongated shaft extending distally from the housing. First and second drive members extend through the elongated shaft to operatively couple respective actuators to respective jaw members such that independent manipulation of one of the actuators may induce pivotal movement of an individual jaw member. A locking member is operatively associated with the first and second drive members, and is selectively movable between locked and unlocked positions. When the locking member is in the locked position, the first and second drive members are coupled to one another and move concurrently to drive the jaw members in a bilateral manner. When the locking member is in the unlocked position, the drive members are decoupled from one another and move independently to permit operation of the instrument in a unilateral manner.

  • Publication number: 20190388143
    Abstract: A surgical forceps includes a housing having a movable handle coupled thereto and movable between an initial position and a compressed position. A drive bar is operably coupled to the movable handle such that movement of the movable handle between the initial and compressed positions effects longitudinal translation of the drive bar. The drive bar further includes a coupling member disposed at a distal end thereof. An end effector assembly includes first and second jaw members movable between spaced-apart and approximated positions. Each jaw member defines a cam slot. A cam pin is slidably disposed within the cam slot of each of the jaw members. The coupling member is configured to releasably engage the cam pin such that movement of the movable handle between the initial position and the compressed position effects movement of the jaw members between the spaced-apart position and the approximated position.

  • Publication number: 20190374298
    Abstract: An enhanced haptic feedback system for medical diagnostics includes a laparoscope configured to be inserted into a body cavity to view tissue and obtain an image of the viewed tissue. An imaging device is configured to acquire physiological data about tissue, process the acquired physiological data, and output the processed data to a graphical user haptic interface (GUHI) capable of generating tangible sensations utilizing one or more haptic interfaces. The GUHI is configured to combine the image received from the laparoscope and the processed physiological data received from the imaging device to provide tangible sensations on both a front screen of the GUHI and a rear screen of the GUHI allowing a surgeon the sensation of feeling for abnormal tissue conditions between the surgeon's hands.
