Abstract
A robotic surgical station is disclosed having a wheeled base, a partial-ring shaped structure slidably coupled to the based to be rotatable relative to the base about a horizontal roll axis passing through a center of the ring shape, a patient's bed restrained to a first arcuate segment of the partial-ring shaped structure at a first mount, a plurality of robotic arms restrained to a second arcuate segment of the partial-ring shaped structure at a second mount, and a remote control unit to command one or more of the plurality of robotic arms. The second arcuate segment is rotatable sideways with respect to the first arcuate segment to allow full access to the patient's bed by a surgeon.
Core Innovation
The invention relates to a robotic surgical station comprising a wheeled base and a partial-ring shaped structure slidably coupled to the base so as to be rotatable about a roll axis (R) orthogonal to a circumferential profile defined by the partial-ring shaped structure and passing through a center (C). The operating table is restrained to a first arcuate segment of the partial-ring shaped structure at a first mount, and a plurality of robotic arms are restrained to a second arcuate segment of the partial-ring shaped structure at a second mount. The second arcuate segment is movable sideways with respect to the first arcuate segment to allow access to the operating table for a surgeon.
The station supports remote actuation of the robotic arms by a surgeon and includes a remote control unit. The partial-ring shaped structure covers an arc of circumference of about 270 degrees out of 360 degrees, with a two-segment arrangement in which the first arcuate segment supports the patient bed while the second arcuate segment supports the robotic arms. A roll rotation mechanism enables rotation about the roll axis (R), and the second segment is rotated sideways relative to the first to clear the operating region for direct surgeon access.
In some embodiments, the system provides selective relative rotation about a pitch axis (P) perpendicular to the roll axis (R), wherein the pitch axis is horizontal in a rest position and intercepts a diameter of the circumferential profile. The station further provides optional yaw about a vertical axis, with telescopic structures and mounts with telescopic adjustment along the yaw axis. The patient bed mounting can be removable, and locking/clamping elements secure an upper operative segment, while the base includes a rack assembly and wheels with locking/retraction for mobility and integration of selectively attachable equipment.
Claims Coverage
The document includes two independent claims. Each independent claim is directed to a robotic surgical station architecture using a partial-ring shaped structure, with one claim focusing on sideways movement of a second arcuate segment for access, and the other claim focusing on selective relative pitch rotation about a pitch axis that intercepts a circumferential diameter.
Sideways movable second arcuate segment for surgeon access
A robotic surgical station having a base rested on the ground, a partial-ring shaped structure slidably coupled to the base for rotation about a roll axis (R) through a center (C), an operating table restrained to a first arcuate segment at a first mount, and a plurality of robotic arms restrained to a second arcuate segment at a second mount and remotely actuated by a surgeon, wherein the second arcuate segment is movable sideways with respect to the first arcuate segment to allow access to the operating table.
Selective relative pitch rotation intercepting a circumferential diameter
A robotic surgical station comprising a patient bed mount and a robotic arm mount positioned on a structure including a partial-ring shaped structure slidably coupled to a base for rotation about a roll axis (R) through a center (C), wherein the patient bed mount and the robotic arm mount provide selective rotation relative to the partial-ring shaped structure about a pitch axis P that is perpendicular to the roll axis R, is horizontal in a rest position, and intercepts a diameter of the circumferential profile.
Across the independent claims, the core coverage centers on a partial-ring shaped structure rotatable about a roll axis, with functional access or workspace control achieved by moving a second arcuate segment sideways relative to a first segment and/or by providing selective relative rotation about a perpendicular pitch axis that intercepts a circumferential diameter.
