Patent number: 11944337Abstract: A surgical instrument with improved end-effector gripping force. The instrument comprises a shaft, which may be inserted into a body of a patient. The articulated end-effector is mounted on the distal extremity of the instrument shaft and comprises a plurality of links interconnected by a plurality of joints, whose movements are remotely actuated by the surgeon's hands. This remote actuation is accomplished through mechanical transmission, mainly along flexible elements, which are able to deliver motion from a set of actuation elements, placed at a proximal extremity of the shaft, to the instrument's articulated end-effector. The articulated end-effector further comprises one or more cam-and-follower mechanisms that are able to amplify the force transmitted by the flexible elements so that the actuation force at the instrument jaws is maximized and the tension on the transmission elements minimized, thus increasing the fatigue resistance and life of the instrument.Type: GrantFiled: May 22, 2022Date of Patent: April 2, 2024Assignee: Distalmotion SAInventor: Ricardo Daniel Rita Beira

Patent number: 10864049Abstract: A docking system for a mechanical telemanipulator is provided, optionally to be used with a mechanical telemanipulator with a master-slave configuration. The docking system is configured to allow for safe and secure immobilization of a handle or master manipulator of a mechanical telemanipulator with a master-slave configuration so as to prevent movement of a slave manipulator or instrument. While the docking element can be deployed on any mechanical telemanipulator, it can advantageously be used on a surgical platform comprising a mechanical telemanipulator with a master-slave configuration. In this context, the docking system can be used to secure the handle portion or master manipulator of the surgical platform to safely prevent undesirable movement of a slave manipulator or surgical instrument.Type: GrantFiled: December 18, 2015Date of Patent: December 15, 2020Assignee: Distalmotion SAInventor: Ricardo Daniel Rita Beira
