  • Publication number: 20220225986
    Abstract: A method for assessing performance of a surgical instrument including one or more drivetrains is disclosed. The method includes sensing via one or more vibration sensors vibrations generated during operation of the one or more drivetrains of the surgical instrument, generating an output signal based on the sensed vibrations, filtering the output signal to generate a filtered signal of the sensed vibrations from the one or more drivetrains, processing the filtered signal to generate a processed signal of the sensed vibrations from the one or more drivetrains, and comparing predetermined threshold values for each of an acceptable status, a marginal status, and a critical status of the surgical instrument to corresponding values of the processed signal.

  • Publication number: 20220218332
    Abstract: A surgical instrument is configured to compensate for battery pack and drivetrain failures. One method includes generating a firing sequence, determining whether a subset of rechargeable battery cells is damaged during the firing sequence, and stepping-up an output voltage of the battery pack to complete the firing sequence in response to a determination that a subset of the rechargeable battery cells is damaged. Another method includes generating a mechanical output to motivate a drivetrain to transmit a motion to a jaw assembly of the surgical instrument, activating a safe mode in response to an acute failure of the drivetrain, and activating a bailout mode in response to a catastrophic failure of the drivetrain. Another method includes driving a drivetrain, sensing and recording vibration information from the drivetrain, generating an output signal based on the vibration information, and determining a status of the surgical instrument based on the output signal.

  • Publication number: 20220218376
    Abstract: Thresholds can be assigned for one or more parameters in connection with the operation of a surgical device. An ultimate threshold can trigger a desired action, including cessation of operations or modification of operations, if the ultimate threshold is reached, or predicted to be reached. In addition, a marginal threshold can trigger a desired action, including improving operations such as slowing operations where the value of a parameter is measured to be between the values defined by a marginal threshold and an ultimate threshold. Multiple thresholds, based on multiple parameters, can be defined, further enabling calibrated usage, such as slowing operations based on exceeding both a marginal threshold based on number of sterilization cycles and exceeding a marginal threshold based on extent to which current draw exceeds a certain value.

  • Patent number: 11376002
    Abstract: Various cartridge assemblies for surgical instruments are provided. Cartridge assemblies can include active sensors for applying stimuli to a tissue clamped by an end effector of the surgical instrument and a circuit configured to determine a tissue type of the tissue according to a change in the tissue parameter detected by the sensor resulting from a stimulus from the active element.

  • Patent number: 8220355
    Abstract: A steering column assembly includes a column jacket coupled to a support bracket. The column jacket is moveable in a longitudinal direction along a longitudinal axis and in a pivotable direction relative to the support bracket about a pivot axis. A locking mechanism interconnects the support bracket and the column jacket, and includes a torsion shaft rotatable about a shaft axis in a first direction and a second direction to move the locking mechanism between a lock position and a release position. A motor includes an output shaft rotatable about a primary axis in a single rotational direction. A linkage interconnects the motor and the torsion shaft of the locking mechanism. The linkage is actuated by rotation of the output shaft in the single rotational direction to rotate the torsion shaft in alternating fashion between the first direction and the second direction.

  • Publication number: 20090070880
    Abstract: Methods and apparatus for validating network alarms, such as alarms from an Intrusion Detection System (IDS). The methods and apparatus validate network threats or alarms by receiving a detected network alarm indicating potentially harmful network activity where the alarm including an alarm destination and an alarm type and obtaining port information of a host targeted by the alarm based on the alarm destination and alarm type. Additionally, a determination is made whether the port at the host is vulnerable to the network alarm based on the obtained port information and the alarm type, and a priority value is assigned to the alarm based at least on the determination of whether the port is vulnerable to the particular network alarm in order to assess validity of the network threat that has triggered the alarm.
