  • Publication number: 20200375651
    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: 10842524
    Abstract: Various surgical devices are provided having mechanisms for preventing premature actuation of a cutting mechanism. These devices generally include a handle having one or more actuators and an effector disposed at a distal end of the device and configured to grasp tissue. When the end effector is in an open position, a firing actuator can be positioned so that it cannot be actuated by a user. For example, the firing actuator can be obstructed by a shield or arm when the end effector is in the open position. In other embodiments, the firing actuator can be hidden in a recess formed in the closure actuator until the end effector is moved to the closed position. When the end effector is in the closed position, the firing actuator can be engaged to advance a cutting mechanism, thereby cutting the tissue grasped by the end effector.

  • 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.
