  • Publication number: 20240148556
    Abstract: A stack of eye shields includes a plurality of eye shields each having a frame with receivers located along the frame and latches located to engage the receivers, and spaced apart elevated support surfaces along and rising above an upper portion of the frame; and a lens installed on the frame and having lens apertures extending through the lens and aligned with the receivers of the frame, with the latches engaged with the receivers securing the lens to the frame. The eye shields are stacked one on top of another with each of the eye shields oriented substantially parallel to one another with each of the elevated surfaces of an overlying one of the frames of the stack being slightly forward of a corresponding one of the elevated surfaces of the underlying frame of the stack, with each frame of each eye shield of the stack having a gap therebetween except at contact surfaces where the elevated support surfaces contact an adjacent lower surface of an overlying eye shield.

  • Patent number: 11950783
    Abstract: A surgical device includes a handle assembly having a controller and an adapter assembly including a tubular housing having a proximal end portion configured to couple to the handle assembly and a distal end portion. The adapter assembly also includes a load sensing assembly disposed with the tubular housing. The load sensing assembly is configured to measure a load exerted on the tubular housing and includes: a sensor body having a pocket defined therein; a load sensor circuit disposed within the pocket and coupled to the sensor body; and a signal processing circuit disposed within the pocket and electrically coupled to the load sensor circuit. The load sensing assembly further includes a cover disposed over the pocket and enclosing the load sensor circuit and the signal processing circuit therein, the cover being coupled to the sensor body thereby forming a first hermetic seal therebetween.

  • Patent number: 11918216
    Abstract: An adapter assembly includes a switch actuator, an actuation bar, and a latch. The switch actuator is movable between a proximal position, in which the switch actuator actuates a switch, and a distal position. The latch is movable between a first position, in which the latch permits proximal movement of the switch actuator, and a second position, in which the latch prevents proximal movement of the switch actuator. The latch is configured to move from the first position toward the second position in response to the actuation bar moving toward a proximal position.
