Patents by Inventor Luis Dussan

Luis Dussan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20200155149
    Abstract: A surgical instrument includes a drive shaft, a motor for rotating the drive shaft, and a motor speed control. The motor speed control includes a first switch and a second switch which are in communication with the motor. The first switch is disposed over and in registration with the second switch. The first switch has an activated state such that the first switch sends a first signal to the motor. The motor rotates the drive shaft in response to the first signal. The second switch sends a second signal to the motor that varies the speed that the motor rotates the drive shaft in response to a force applied to the second switch by the first switch.

  • Publication number: 20190293828
    Abstract: An adapter assembly includes an elongated body configured to couple to a handle assembly and a loading unit assembly. The adapter assembly includes an oscillator configured to output a voltage signal. A sensor determines a connection status of the loading unit assembly coupled to the adapter assembly based on a change in the voltage signal. The voltage signal includes a rectified voltage output and an induced voltage output and changes in response to the approximation of a winding disposed within a loading unit assembly to the oscillator.

  • Patent number: 10190888
    Abstract: A surgical stapling instrument includes an elongate body, a cartridge assembly, an anvil assembly, and a linear position assembly including a pair of opposing magnets, and a plurality of sensors. The elongate body has a central shaft longitudinally translatable therethrough. The cartridge assembly is coupled to a distal end of the elongate body. The anvil assembly is selectively connectable to the central shaft of the elongate body. The magnets are mounted to the central shaft. The sensors are fixed within the cartridge assembly and configured to sense a change in a magnetic field of the magnets upon a longitudinal movement of the magnets in response to an actuation of the central shaft to determine a linear position of the anvil assembly relative to the staple cartridge.
