  • Patent number: 11944337
    Abstract: 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.

  • Publication number: 20230149002
    Abstract: A sterile interface for a surgical platform is provided, optionally to be used with a mechanical telemanipulator. The sterile interface is configured to allow for transmission of motion without dimensional inconsistencies between a non-sterile surgical platform and a sterile surgical instrument that are related to one another in a master-slave configuration. The sterile interface is configured to allow for multiple changes of sterile surgical instruments during a surgical procedure without contaminating the sterile field. The sterile interface allows for interchangeable sterile articulated surgical instruments to be attached to the surgical platform without coming into contact with non-sterile portions of the surgical platform.

  • Publication number: 20230054176
    Abstract: Disclosed is a reusable surgical instrument (1) with an articulated end-effector (3), such as a dissector, scissor or grasper, to enhance a surgeon's performance during various surgical procedures. The longitudinal axis of the instrument is defined by a shaft (2), comprising an internal structural element (2?) covered by an external tube (2?), which may be inserted through a surgical incision into the body of a patient, optionally through a trocar. The articulated end-effector (3) is mounted on the distal extremity of the shaft's internal structural element 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 via mechanical transmission (5, 6, 7), mainly composed of flexible elements, which are able to deliver motion from a set of actuation elements, placed at a proximal extremity of the shaft (2), to the instrument's articulated end-effector (3).

  • Publication number: 20210369360
    Abstract: A novel mechanical system, based on a new cable driven mechanical transmission, able to provide sufficient dexterity, stiffness, speed, precision and payload capacity to actuate multi-DOF micro-manipulators. Besides the possibility of being used in several articulated surgical instruments and robotic systems for surgery or other applications involving remote manipulation, it enables the design of a novel fully mechanical surgical instrument, which offer the advantages of: conventional laparoscopy (low cost, tactile feedback, high payload capacity) combined with the advantages of single port surgery (single incision, starless surgery, navigation through several quadrants of the abdominal cavity) and robotic surgery (greater degrees of freedom, short learning curve, high stiffness, high precision, increased intuition).

  • Patent number: 10864049
    Abstract: 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.
