Abstract:
An instrument sterile adapter for coupling a surgical instrument and an instrument carriage includes an adapter control surface that extends control features of a control surface of the instrument carriage and receives an instrument control surface of the surgical instrument. A curved surface extends from the adapter control surface. The curved surface receives a corresponding curved surface on the instrument control surface. A bullet portion on the curved surface may engage a bullet receiving feature in the corresponding curved surface on the instrument control surface. A locating pin or slot on the adapter control surface may engage a locating slot or pin on the instrument control surface. The instrument control surface may be supported by landing pads on the adapter control surface. Latch arms on the adapter control surface may engage latch receptacles on the instrument control surface.
Abstract:
A sterile adapter for coupling a surgical instrument and a surgical instrument manipulator includes a bottom component and a coupling component. The bottom component includes a bottom component opening with a bottom lip having a locking mechanism. The coupling component is rotatably coupled to the bottom component. The coupling component includes an engagement feature that engages the surgical instrument manipulator. The coupling component further includes a locking mechanism opening that engages the locking mechanism when the engagement feature has not engaged the surgical instrument manipulator. The coupling component may include a retention tab that is aligned with the keyway to insert the coupling component into the bottom component opening and then misaligned with the keyway to retain the coupling component in the bottom component opening. A ramp may be provided on a leading edge of a pocket to facilitate engaging the coupling component with the surgical instrument manipulator.
Abstract:
A patient side cart for a teleoperated surgical system comprises a base, a manipulator portion extending from the base and configured to hold one or more surgical instruments, four wheels mounted to the base to permit movement of the cart, and a suspension system. The suspension system may be configured to transition the cart between a first state in which the cart behaves as a three-wheeled cart and a second state in which the cart behaves as a four-wheeled cart.
Abstract:
A remote center manipulator for use in minimally invasive robotic surgery includes a base link held stationary relative to a patient, an instrument holder, and a linkage coupling the instrument holder to the base link. First and second links of the linkage are coupled to limit motion of the second link to rotation about a first axis intersecting a remote center of manipulation. A parallelogram linkage portion of the linkage pitches the instrument holder around a second axis that intersects the remote center of manipulation. The second axis is angularly offset from the first axis by a non-zero angle other than 90 degrees.
Abstract:
An instrument sterile adapter couples a surgical instrument and an instrument carriage. The instrument sterile adapter includes an instrument plate that provides a first surface to receive the surgical instrument and a latch plate joined to the instrument plate. The latch plate includes a second surface to receive the instrument carriage and latch structures. Each latch structure has a carriage latch arm that extends away from the second surface of the latch plate and an instrument latch arm joined to the carriage latch arm. The instrument latch arm extends through the instrument plate and away from the first surface of the instrument plate. A connecting member flexibly connects the carriage latch arm and the instrument latch arm to a remainder of the latch plate. The connecting member may be perpendicular to the latch arms. The latch arms may engage fixed locking surfaces in the instrument carriage and the surgical instrument.
Abstract:
A robotic assembly is configured to support, insert, retract, and actuate a surgical instrument mounted to the robotic assembly. The robotic assembly includes an instrument holder base member, a motor housing moveably mounted to the instrument holder base member, a carriage drive mechanism operable to translate the motor housing along the instrument holder base member, a plurality of drive motors, and a plurality of output drive couplings driven by the drive motors. One or more of the drive motors includes one or more magnetic flux shields to inhibit magnetic interference with an adjacent drive motor and/or with an adjacent motor orientation sensor.
Abstract:
A robotic surgery system includes an orienting platform, a support linkage movably supporting the orienting platform, a plurality of surgical instrument manipulators, and a plurality of set-up linkages. Each of the manipulators includes an instrument holder and is operable to rotate the instrument holder around a remote center of manipulation (RC). At least one of the manipulators includes a reorientation mechanism that when actuated moves the attached manipulator through a motion that maintains the associated RC in a fixed position.
