  • Patent number: 11969142
    Abstract: A method of compressing tissue during a surgical procedure is disclosed. The method comprises obtaining a surgical instrument comprising an end effector, wherein the end effector comprises a first jaw and a second jaw, establishing a communication pathway between the surgical instrument and a surgical hub, and inserting the surgical instrument into a surgical site. The method further comprises compressing tissue between the first jaw and the second jaw, determining a location of the compressed tissue with respect to at least one of the first jaw and the second jaw, communicating the determined location of the compressed tissue to the surgical hub, and displaying the determined location of the compressed tissue on a visual feedback device.

  • Patent number: 11944884
    Abstract: A reinforced die for use in a throwing game and method of manufacture of same are provided. Having corners reinforced with multiple rows of machine stitched threads, multiple layers of inner lining padding the corners, and filler material within the inner lining layers helps the die maintain distinct sides and resist deformation even after being thrown extensively against a hard surface. The use of machine stitching to reinforce the die allows to impart uniform strength to all sides of the die, further increasing resistance to deformation. The material of the housing, such as duck cloth, is weather resistant, durable, and has a friction coefficient that is high enough to prevent excessive sliding of the die from a board upon which the die is thrown, but low enough to prevent damage to the board.

  • Patent number: 11918212
    Abstract: A surgical instrument including a surgical end effector and a threaded rotary input shaft. An actuator member is in operable engagement with the surgical end effector and is in selective threaded engagement with the threaded rotary input shaft such that when the actuator member is in an engaged configuration, rotation of said threaded rotary input shaft causes the actuator member to move axially to impart an actuation motion to the surgical end effector and when the actuator member is in a disengaged configuration, rotation of the threaded rotary input shaft will not be imparted to the actuator member. A switch may be employed for selectively moving the actuator between the engaged and disengaged configurations. A locking system may be employed for preventing axial movement of the actuator member when the actuator member is in the disengaged configuration.

  • Patent number: 5830390
    Abstract: A method and apparatus for a nonsynchronous system for continuously molding articles from a material cured by the control of temperature and pressure. The apparatus includes a multi-section self-clamping mold, a controller system, a material injector, a transfer system, a curing apparatus for curing the articles, and a mold separator-assembler. The method comprises pre-treating and then assembling the mold in a clamped condition. Under the control of the controller system, the mold is then injected with material from the injector, and moved by the transfer system through the curing apparatus to cure the material within the mold. Once cured, the controller system moves the mold to the mold separator-assembler via the transfer system. The mold is then disassembled into sections, the molded article is removed, and the sections are pre-treated and reassembled, for the next injection operation.

  • Patent number: 5286186
    Abstract: An apparatus for injecting molding material into a self-clamping mole. The apparatus includes a support frame with spaced plates and support bars interconnecting the plates, and a C-shaped opening formed in the plates. An injector is included for injecting molding material into the self-clamping mold under pressure, and an extruder for providing molding material to the injector. Temperature controllers are also provided for controlling the temperature of the molding material within the injector and extruder. A lift mechanism supported on the frame provides clamped engagement between the self-clamping mold and the frame. During the injection operation wherein the injector is engaged with the mold, the lift mechanism clamps the mold to resist internal mold forces resulting from the injection of molding material.

  • Patent number: 5183605
    Abstract: A method for injecting molding material into a self-clamping mold. The method comprises the steps of supporting the mold in a support frame clamped in engagement with an injector using a lift mechanism. The pressure required to inject material into the mold is pre-determined and applied by the lifting mechanism to maintain the condition and position of self-clamping mold during injection, and is a function of the area of exposed sprue openings in the mold. The molding material is transferred into the injector. The temperature of the molding material transferred to the mold is controlled, and the molding material is injected into the mold under the pre-determined pressure using the injector, while clamping the mold within the frame with a force of less than 25 tons.
