摘要： Methods and devices for controlling motorized surgical devices are provided. In general, the methods and devices can allow a surgical device to grasp and cut tissue. In some embodiments, the device can include at least one sensor and a motor, and an output of the motor can be configured to be adjusted based at least in part on an output from the at least one sensor. The output of the motor can be configured to provide power for translation of a cutting element along an end effector of the device. Adjusting the motor's output can cause the cutting element to translate through the end effector at different speeds, thereby allowing the cutting element to cut through tissue being grasped by the end effector at different speeds.

摘要： In various embodiments, a surgical instrument is disclosed. The surgical instrument comprises a handle assembly having a closure trigger, a closure actuator coupled to the closure trigger at a first pivot, and a closure spring. The closure actuator moves proximally on a longitudinal axis in response to actuation of the closure trigger. The closure spring applies a force vector to the closure spring tangential to the longitudinal axis. A shaft assembly is coupled to the handle assembly. An end effector is coupled to a distal end of the shaft assembly. The end effector comprises a jaw assembly comprising a first jaw member and a second jaw member. The first jaw member is pivotally moveable with respect to the second jaw member. At least one of the first and second jaw members are operatively coupled to the closure actuator.

摘要： An apparatus comprises an end effector, a shaft, and a handpiece. The end effector is operable to manipulate tissue. The shaft is in communication with the end effector. The shaft includes a firing beam operable to actuate a portion of the end effector. The handpiece comprises a pivoting trigger that is operable to distally advance a firing beam driver to advance the firing beam. The handpiece also comprises an activation button and lockout assembly. The lockout assembly is movable between a locked and unlocked state. In the locked state, the lockout assembly blocks a portion of the firing beam driver from advancing. In the unlocked state, the lockout assembly allows the firing beam driver to advance.

摘要： An apparatus comprises a body, a shaft, an end effector, and a firing beam. The shaft extends distally from the body. The end effector is positioned at the distal end of the shaft. The end effector comprises a first jaw and a second jaw, with the first jaw being pivotable toward the second jaw. The firing beam is operable to translate relative to the end effector to thereby drive the first jaw toward the second jaw. The firing beam includes a deformable portion operable to deform in response to a stress imposed by the end effector on the firing beam as the jaws clamp on dense or thick tissue. The deformable portion is defined in part by a cutout. A compliance restriction feature restricts deformation in the firing beam. A resilient member biases the firing beam to a non-deformed configuration.

摘要： A medical instrument is disclosed. The medical instrument includes at least one electrical contact, a battery, a radio frequency (RF) generation circuit coupled to and operated by the battery and operable to generate an RF drive signal and to provide the RF drive signal to the at least one electrical contact, and a battery discharge circuit coupled to the battery. A processor is coupled to the battery discharge circuit and a memory is coupled to the processor. The memory stores machine executable instructions that when executed cause the processor to monitor activation of the RF generation circuit and disable the RF generation circuit when the RF drive signal is fired a predetermined number of times. The medical instrument may include an activation switch and/or a disposal switch supported by the housing.

摘要： Surgical devices and methods are described herein that provide improved motor control and feedback, thereby combining advantages of manually-operated and powered surgical devices. In one embodiment, a surgical device includes a proximal handle portion that includes a motor, a distal end effector coupled to the handle portion, and a cutting element configured to cut tissue engaged by the end effector, wherein the motor is configured to supply power that moves the cutting element. The device also includes a motor control mechanism configured to cause the amount of the power to dynamically change in response to a manual user input when the cutting element is moving.

摘要： A surgical end effector has a first jaw comprising a first electrode and a second jaw, wherein at least one of the first jaw and the second jaw is movable relative to the other one of the first jaw and the second jaw to transition the end effector between an open configuration, an approximated configuration, and a fully approximated configuration. The second jaw includes a second electrode and a spacer extending from the second electrode, wherein the spacer is configured to maintain a predetermined distance between the first electrode and the second electrode when the end effector is in the fully approximated configuration, wherein the spacer is in contact with the first electrode in the fully approximated configuration, wherein the spacer is spaced apart from the first electrode in the open configuration, and wherein the spacer is comprised of a semi-conductive material.
