  • Publication number: 20200268408
    Abstract: Systems, devices, and methods are operable to track usage of a surgical instrument and modify the performance of the surgical instrument based on the prior usage of the surgical instrument. Some surgical instruments are designed to have a limited service life beginning at their first use, or a limit to their overall usage in order to ensure safe use of the sensitive instruments. However, a lack of ability to track usage characteristics when the instrument is separated from an external power supply allows for user abuse and avoidance of such safety mechanisms. Adding a battery or capacitor to the instrument may allow for an ability to track usage when the instrument is separated from an external power supply. Implementing special user prompts, device use ratios, and device use half-life upon powering down of an instrument may additionally be used to prevent circumvention of safety features.

  • Patent number: 10751117
    Abstract: An end effector of an electrosurgical device may include a discharge port in communication with a first fluid path, an aspiration port in communication with a second fluid path, a first and second electrode, and a diverter in mechanical communication with the two electrodes. The diverter may receive, on its surface, a fluid emitted by the discharge port, and maintain a contact of the fluid with the first and second electrodes. The diverter may be further configured to prevent an aspiration, by the aspiration port, of the fluid on its surface. An electrosurgical device may include a source port in communication with a first fluid path, an evacuation port in communication with a second fluid path, a first and second electrode, and a housing. The device may include a shaft extending distally from the housing and the end effector as described above.

  • Patent number: 10743898
    Abstract: Surgical devices are provided having power-assisted or fully powered jaw closure. The devices herein generally include a handle portion, an elongate shaft, and an effector having first and second jaws configured to engage tissue. A motor and one or more compression springs can be operatively coupled, and activation of the motor can compress the spring(s) to reduce the amount of user supplied force to compress tissue between the jaws. In some embodiments, the devices can be configured to regulate an amount of compression applied by the jaws prior to, during, and/or after cutting of the tissue to promote hemostasis. For example, the devices can include sensors, processors, and/or other components that analyze data indicative of tissue type and tissue load. Based on this feedback, the device can automatically adjust the amount of compression or energy applied to the tissue to seal the tissue.

  • Patent number: 10709470
    Abstract: An ultrasonic surgical instrument includes a body, an ultrasonic transducer rotatably supported within the body and having a threaded distal end, a shaft extending from the body, a waveguide extending through the shaft and having a threaded proximal end configured to threadedly engage the threaded distal end to define a threaded coupling, and an end effector at a distal end of the shaft. An integrated torque wrench mechanism is arranged within the body and includes a first torque wrench member rotationally coupled with a proximal end of the transducer, and a second torque wrench member arranged proximally of the first torque wrench member. The torque wrench members are configured to selectively couple together and frictionally engage one another to facilitate application of a predetermined maximum torque to the threaded coupling. The torque wrench members are configured to automatically decouple upon application of the predetermined maximum torque to the threaded coupling.

  • Patent number: 10653897
    Abstract: A surgical instrument having a transmission assembly, a transducer, and a handle assembly is configured for coupling the transmission assembly to the handle assembly using a locking mechanism. The locking mechanism is operable to restrict the rotational movement of an actuator coupling member and the transducer relative to the handle assembly. The locking mechanism may also be operable to lock a trigger of the handle assembly in a first position. An inner tubular actuating member of the transmission assembly may be threadably attachable to the actuator coupling member or the actuator coupling member may include a latching mechanism to couple to a flared portion of the inner tubular actuating member. A waveguide of the transmission assembly may also be threadably attachable to the transducer. In one alternative, the trigger may be configured to operate the locking mechanism, either in the first position or when pivoted distally to a third position.
