  • Patent number: 11944338
    Abstract: Thresholds can be assigned for one or more parameters in connection with the operation of a surgical device. An ultimate threshold can trigger a desired action, including cessation of operations or modification of operations, if the ultimate threshold is reached, or predicted to be reached. In addition, a marginal threshold can trigger a desired action, including improving operations such as slowing operations where the value of a parameter is measured to be between the values defined by a marginal threshold and an ultimate threshold. Multiple thresholds, based on multiple parameters, can be defined, further enabling calibrated usage, such as slowing operations based on exceeding both a marginal threshold based on number of sterilization cycles and exceeding a marginal threshold based on extent to which current draw exceeds a certain value.

  • Patent number: 11937799
    Abstract: Surgical sealing systems are provided. In one exemplary embodiment, a surgical sealing system includes a seal housing having a plurality of ports, in which each of port has a nominal size and shape, is configured to assume a selected and/or shape that is different from the nominal size and shape, and is constrained by the size and shape of each of the other plurality of ports. The position of an instrument and a force applied thereto is effective to change the size and/or shape of the ports based on the movement, direction, and force of the instrument, and the ability to alter the nominal shape of any one port is constrained or limited by the size and shape of the other ports, thereby enabling a force applied to one instrument positioned within one of the plurality of ports to stabilize at least one other instrument positioned within others of the plurality of ports.
