  • Patent number: 9861378
    Abstract: A surgical instrument includes an elongated shaft having a distal portion and a proximal portion coupled to a housing. An inner shaft member extends at least partially through the elongated shaft and is selectively movable in a longitudinal direction. An end effector is supported by the distal portion of the elongated shaft. The end effector includes upper and lower jaw members pivotally coupled to the distal portion of the elongated shaft about a pivot axis and including a pair of laterally spaced flanges. The pairs of flanges of the jaw members are arranged in an offset configuration such that one flange of the upper jaw member is positioned on a laterally exterior side of a corresponding flange of the lower jaw member, and the other flange of the upper jaw member is positioned on a laterally interior side of the other flange of the lower jaw member.

    Abstract: A surgical instrument includes a shell having a housing and a shaft. The shell including first and second shell components configured to engage one another to form the shell, each of which is monolithically formed to include a housing portion and a shaft portion. Upon engagement of the first and second shell components with one another, the housing portions cooperate to form the housing of the shell while the shaft portions cooperate to form the shaft of the shell. An end effector assembly is operably coupled to the shaft at a distal end of the shaft. A handle assembly is operably coupled to the housing. A drive assembly disposed within the shell is operably coupled between the handle assembly and the end effector assembly such that actuation of the handle assembly manipulates the end effector assembly.

  • Publication number: 20170215943
    Abstract: A surgical instrument includes a housing, a shaft extending distally from the housing, an end effector disposed at a distal end of the shaft, an actuator operably coupled to the housing, an actuation assembly, and a sensor module. The actuation assembly extends through the housing and the shaft and includes a distal end operably coupled to the end effector or a component associated therewith, a proximal end operably coupled to the actuator, and a spring. Actuation of the actuator manipulates the end effector or deploys the component relative thereto. The sensor module is disposed within the housing and configured to sense a property of the spring indicative of an amount the spring has been compressed. The sensor module is further configured, based upon the sensed property, to determine a condition of the end effector or the relative position of the component.

  • Publication number: 20170187420
    Abstract: A powerline communication system includes a plurality of rail segments. Each of the rail segments is electrically isolated from other rail segments, and each receives power from a rail segment power supply. At least one cart operates on the rail segments. The cart has a powerline communications controller. Each rail segment has a current state defined by how many and which carts are operating on the rail segment. A central coordinator is coupled to each rail segment and configured to execute a channel estimation using a sounding protocol on its rail segment. The central coordinators store tone maps associated with the possible states of its rail segment, and possibly its adjacent rail segment. A main controller communicates with each central coordinator to direct the state and future state of its segment so that tone maps and network keys can be managed by the CCo in advance of an imminent state change.
