  • Patent number: 11116505
    Abstract: A buttress applier cartridge assembly includes a buttress assembly and a buttress applier cartridge. The buttress assembly includes a buttress configured to support a staple formed therein as well an adhesive layer for adhering to an end effector. The buttress applier cartridge includes a housing defining a gap extending in a longitudinal direction as well as a platform. The platform extends longitudinally from a proximal portion to a distal portion and is exposed in a transverse direction adjacent to the gap. The proximal and distal portions respectively have a proximal stiffness and a different, distal stiffness in the transverse direction. Thereby, the proximal and distal portions support the buttress assembly thereon to deform with the proximal and distal stiffnesses and provide reactionary forces of at least the predetermined minimum force while receiving the end effector for accommodating various camber orientations of the end effector.

    Abstract: A pneumatic nail gun comprises a working piston connected to a driving ram that is configured to drive in a fastening means and is pressurized by air when a driving process is initiated. A hand-operated trigger and a contact sensor. Simultaneous actuation of the hand-operated trigger and contact sensor activates a first control valve and initiates the driving process if the pressure in a safety control chamber is above a given pressure threshold. A second control valve is configured to be activated upon actuation of the trigger. The safety control chamber is continuously de-aerated via a throttle and is separated from a pressurized casing interior when the second control valve is activated.

  • Patent number: 11104466
    Abstract: Robotic pick-and-place automation is used to transfer oral solid pharmaceuticals from moveable trays or canisters. Sensors are used to verify that the pharmaceuticals have been properly placed in the desired pharmaceutical locations precisely according to the patient prescription data. A pharmacist places pharmaceutical products within dispensing trays or canisters to present the pharmaceutical products for picking and placing via the robotic pick-and-place machinery. Once the canister or tray is located adjacent the pick-and-place device, a sensor or imaging unit associated with the pick-and-place device verifies that the pharmaceutical product, the size, shape, and/or color of an expected pharmaceutical product that is to be placed within the packaging material in accordance with patient prescription data stored by a computer associated with the system.

  • Patent number: 11097407
    Abstract: A driving tool drives a fastener by a striking mechanism. The driving tool includes a trigger, a contact arm, a contact lever and a regulator. The trigger and the contact arm receive manipulations which operate the striking mechanism. The contact lever is movable according to operations of the trigger and the contact arm and switches operating states of the striking mechanism. The regulator regulates a movement of the contact lever according to a movement of the contact arm in which another manipulation is released. The regulator operates with a fluid for operating the striking mechanism, and keeps the contact lever at an operation standby position where the contact lever is operated by manipulation of the contact arm for a predetermined time period by controlling a flow rate of the fluid.
