Publication number: 20220202516Abstract: A robotic surgical assembly includes a slave manipulator with an actuator, a pushing device connected to the actuator, a sensor detecting a contact force on the pushing device, a position sensing system, and a control unit. A surgical instrument is detachable to the slave manipulator and separated from the slave manipulator by a sterile barrier. The surgical instrument includes a frame; an articulated link; a tendon associated with the actuator, having proximal and distal portions secured to the link. A transmission device in contact with the tendon proximal portion exerts a traction action. The transmission device has one degree of freedom of motion relative to the frame. The pushing device releasably and selectively connects with the transmission device to transmit a pushing action to the transmission device through the sterile barrier. An elastic device biases the transmission device to exert a traction action on the tendon.Type: ApplicationFiled: March 17, 2022Publication date: June 30, 2022Applicant: MEDICAL MICROINSTRUMENTS S.P.A.Inventors: Massimiliano SIMI, Giuseppe Maria PRISCO, Cesare STEFANINI

Publication number: 20210369374Abstract: A master controller assembly for a robotic surgery system has a slave robot assembly, a slave surgical instrument and a control unit. The master controller assembly has a master input tool and a convex manipulandum surface to be hand-held by surgeon's fingers. The master input tool is mechanically unconstrained from the slave robot assembly, naturally movable, rotatable and spinnable by the surgeon. The master input tool includes first and second elongated elements having respectively a first element elongated body and a second element elongated body. A tool joint connects and articulates the first and second element elongated bodies. A sensing assembly detects mutual position of the first and second element elongated bodies, so that a gripping pressure action exerted by the surgeon's fingers on the master input tool moves the first and second element elongated bodies closer and determines a paired grip motion of a surgical grip device.Type: ApplicationFiled: May 17, 2019Publication date: December 2, 2021Inventors: Massimiliano SIMI, Giuseppe Maria PRISCO
