  • Patent number: 11730649
    Abstract: A patient turning device for a patient support apparatus. The patient turning device includes a first and second bladder assembly each including a plurality of layers and seals defining a bladder volume. The bladder volumes are selectively inflatable with fluid to expand the respective bladder assembly, and consequently move a patient support surface of the patient support apparatus. A portion of a lower layer of the first bladder assembly and a portion of an upper layer of the second bladder assembly define an overlapping region of the bladder volumes. The patient turning device is coupled to an underside of a carrier sheet and positioned between a crib assembly and a bottom cover. An augmenting feature is configured to resiliently expand as at least one of the first and second bladder assemblies receives the fluid to move at least a portion of the crib assembly away from a patient support deck.

  • Patent number: 11730400
    Abstract: A patient support apparatus includes a plurality of primary sensors adapted to measure different parameters used in the control of the patient support apparatus. One or more suites of secondary sensors are added to the patient support apparatus to provide data about the primary sensors. The secondary sensors may be used to detect errors in the primary sensors, to modify outputs from the primary sensors, and/or to provide usage and/or diagnostic data about the use of the patient support apparatus. The suite(s) of secondary sensors may measure parameters that affect the outputs of one or more of the primary sensors. In some embodiments, the suite(s) of secondary sensors include one or more dormant sensors that are not used on the patient support apparatus until a code modification is received from one or more external sources instructing the control system of the patient support apparatus to begin using the dormant sensor(s).

  • Publication number: 20230255790
    Abstract: A bone graft loading system includes a loading funnel, syringe, cannula, plunger, and loading tool. The loading funnel includes an interior passageway to receive the cannula and a syringe docking portion. The syringe may be coupled to the syringe docking portion so that it extends along a longitudinal axis that is transverse to the longitudinal axes of the cannula and the loading funnel. A user may advance bone graft from the syringe to a holding area of the loading funnel. The user may then move the loading tool through the holding area and into the interior space of the cannula to load the cannula with bone graft. This process may be repeated until the cannula is fully loaded with bone graft. The cannula and the plunger inside the cannula may then be removed from the loading funnel and coupled to an injector assembly for use in surgery.

  • Publication number: 20230255708
    Abstract: Surgical systems and methods for generating a tool path. A manipulator is configured to support and move a surgical instrument. Controller(s) obtain data that defines a volume of tissue to be removed from a surgical site. The controller(s) operate the manipulator to move the surgical instrument to remove first portions of the volume and acquire data defining the first portions removed from the volume. The controller(s) identify, based on the volume and the acquired data, additional portions of the volume of tissue that require removal. The controller(s) generate a tool path that passes through the additional portions and operate the manipulator to move the surgical instrument along the tool path to remove the additional portions.

  • Patent number: 11723683
    Abstract: Systems (10) and methods (12) of controlling an ultrasonic surgical tool (20) with a console (22) are provided. A first drive signal (40) is applied to the ultrasonic surgical tool (20). A characteristic of a harmonic signal (44) resulting from application of the first drive signal (40) to the ultrasonic surgical tool (20) is acquired. A cancellation signal (70) is generated based on the characteristic of the harmonic signal (44). The first drive signal (40) and the cancellation signal (70) are combined to produce a second drive signal (80) that is sinusoidal. The second drive signal (80) is applied to the ultrasonic surgical tool (20) such that presence of the harmonic signal (44) resulting from application of the second drive signal (80) is reduced relative to presence of the harmonic signal (44) resulting from application of the first drive signal (40).

  • Patent number: 11723793
    Abstract: A thermal transfer device for providing thermal treatment to a patient. A patient support portion supporting and contacting the patient includes a first segment of a fluid flow path to receive a fluid from a fluid source. A flexible covering coupled and movable relative to the patient support portion defines a space therebetween that substantially conforms to the patient. The flexible covering includes a second segment of the fluid flow path. The fluid is circulated through an inlet, an outlet, and fluid flow path for supplying heat to or removing heat from the patient support portion and the flexible covering. A fluid circulation system with a controller may selectively adjust heat transfer from temperature zones defining the patient support portion. The thermal transfer device or a mattress cover may provide for controlling the microclimate, or conditions at or near the interface between the patient and the patient support portion.

  • Patent number: 11723821
    Abstract: A patient support apparatus comprising a base movable about a floor surface and a deck comprising sections movable between deck configurations including an egress deck configuration. An articulation system coupled to the deck moves the sections. A lift mechanism moves the deck relative to the base between lift configurations including an egress lift configuration. An egress input is arranged for actuation by a user. A bed detection system monitors data associated with the patient support apparatus and communicates with a remote station. A controller interrupts communication of the bed detection system with the remote station, drives the articulation system to move the sections to the egress deck configuration, and drives the lift mechanism to move the support frame to the egress lift configuration in response to actuation of the egress input.
