  • Patent number: 8220468
    Abstract: A robotic surgical system includes a sterile surgical instrument, a robotic surgical manipulator, and a sterile drape covering at least a portion of the robotic surgical manipulator. The surgical instrument has a proximal interface and a distal end effector. The proximal interface includes a gimbal assembly with two intersecting rotational axes coupled to the distal end effector. The robotic surgical manipulator has a drive plate that bears against the gimbal assembly. The drive plate has two degrees of rotational freedom about a center of motion that is coincident with an intersection of the axes of the gimbal assembly. The sterile drape includes a sterile sheet covers at least a portion of the robotic surgical manipulator, a frame bonded to the sterile sheet, an instrument interface that covers the drive plate of the robotic surgical manipulator, and a diaphragm that connects the instrument interface to the frame.

  • Publication number: 20110277776
    Abstract: A sterile drape, a surgical system with the drape, and a draping method are provided. In one embodiment, a sterile drape includes a plurality of drape pockets, each of the drape pockets including an exterior surface to be adjacent a sterile field for performing a surgical procedure and an interior surface to be adjacent a non-sterile instrument manipulator coupled to a manipulator arm of a robotic surgical system. The drape further includes a plurality of flexible membranes at a distal face of each of the drape pockets for interfacing between outputs of an instrument manipulator and inputs of a respective surgical instrument, and a rotatable seal adapted to couple a proximal opening of each of the drape pockets to a rotatable element at a distal end of the manipulator arm.

  • Publication number: 20110282356
    Abstract: An instrument manipulator and a robotic surgical system including an instrument manipulator are provided. In one embodiment, an instrument manipulator includes a plurality of independent actuator drive modules, each of the plurality of actuator drive modules including an actuator output, wherein each of the actuator outputs are configured to independently actuate a corresponding actuator input of a surgical instrument without force input from another actuator output. The instrument manipulator further includes a frame housing the plurality of independent actuator drive modules, the frame including a distal end from which each of the actuator outputs distally protrude for engaging the corresponding actuator inputs of the surgical instrument.
