Abstract

A surgical positioning cart configured to support a surgical robotic device thereon a distal side configured to face a surgical entry site of a patient, comprises a base movable at least along a horizontal reference plane, a head pivotable relative to the horizontal plane to define therewith different inclination angles at least in a plane comprising vertical and longitudinal axes of the cart; a slider configured to fixedly receive at least a portion of the surgical robotic device thereon and mounted to the head so as to be pivotable therewith and be movable relative thereto at least along the longitudinal axis; and a neck connecting between the base and the head pivotally mounted thereto, having an adjustable height defined by a length of the neck in the vertical direction.

Core Innovation

The invention provides a mobile surgical positioning cart for positioning a dockable surgical-robotic device. The cart includes a wheeled base section, an intermediate section extending upwardly from the base section with user-adjustable height, and an upper section mounted atop the intermediate section. The upper section is pivotable relative to the intermediate section throughout a range of inclination angles and includes a slidable docking platform operative to support the dockable surgical-robotic device.

The slidable docking platform is configured to move in multiple coordinated degrees of freedom. When the height of the intermediate section is adjusted, the docking platform is operative to be displaced in a vertical direction. When the upper section is pivoted relative to the intermediate section, the docking platform pivots about a pitch axis together with a non-sliding portion of the upper section, and the docking platform is operative to slide longitudinally in a longitudinal sliding direction relative to the non-sliding portion, thereby extending a length of the upper section.

The cart design emphasizes a compact footprint suitable for positioning between spread legs, using geometric ratios and projection constraints. The disclosed configuration supports the integration of controllers and actuators, safety features such as locks and sensors, and stabilizing elements such as wheel brakes and supporting legs. A docking and locking interface engages the surgical robotic device and can reversibly lock it while allowing relative movement associated with the slidable docking platform and pivoting upper section.

A related operating approach is described for positioning the surgical robotic device relative to a surgical entry site by independently coordinating vertical displacement via the intermediate section height adjustment, pivoting about the pitch axis, and longitudinal sliding of the docking platform to extend the upper section. The cart can mount the surgical robotic device on the docking platform, optionally locking it thereon, while enabling the docking platform to advance distally without moving the entire cart.

Claims Coverage

The document includes two independent claims: one directed to the cart structure and one directed to a method for positioning the surgical robotic device. The inventive features focus on a wheeled cart with a user-adjustable-height intermediate section, a pivotable upper section, and a slidable docking platform that provides vertical displacement, pitch-axis pivoting, and longitudinal extension relative to a non-sliding portion. Additional claim refinements further constrain footprint geometry, inclination range, control functions, and reversible docking/locking behavior.

Across the independent claims, the core coverage is the combination of a wheeled surgical positioning cart with a user-adjustable-height intermediate section and a pivotable upper section, together with a slidable docking platform that yields vertical displacement, pitch-axis pivoting with a non-sliding portion, and longitudinal sliding that extends the length of the upper section. The method claim applies these same coordinated motions to position the surgical robotic device, including mounting and optionally reversible locking on the slidable docking platform.
