摘要： Various exemplary methods and devices for actuating surgical instruments are provided. In general, a surgical device can include one or more actuation shafts configured to facilitate actuation of the device. In an exemplary embodiment, the device can include four actuation shafts, two actuation shafts to facilitate articulation of the device, one actuation shaft to facilitate opening and closing of jaws at the end of the device, and one actuation shaft to facilitate moving and cutting element of the device. In an exemplary embodiment, each of the one or more actuation shafts can include a distal elongate member and a proximal elongate member having a proximal end attached to a distal end of the distal elongate member. The proximal elongate member can be rigid, and the distal elongate member can be flexible.

摘要： Various ultrasonic surgical instruments are disclosed. At least one disclosed surgical instrument includes a waveguide including a blade and a transducer base plate. The transducer base plate coupled to the waveguide to define a joint at an interface between the waveguide and the transducer base plate. The transducer base plate including first and second sides defining corresponding first and second flat faces configured to receive first and second piezoelectric elements. The first and second piezoelectric elements are configured to operate in a D31 mode.

摘要： A surgical instrument includes an instrument body, an ultrasonic transducer assembly, and a slip lock having a lock member configured to move between unlocked and locked positions and an arrester. The transducer assembly is rotatably mounted along a longitudinal axis within the body such that the transducer assembly is configured to selectively rotate. The arrester has a catch portion and a deflectable portion, which is configured to deflect relative to the transducer assembly. The catch portion is configured to seize the transducer assembly and selectively inhibit rotation for rotatably coupling with the acoustic waveguide up to a predetermined torque. The deflectable portion is configured to deflect relative to the transducer assembly upon receiving a torque greater than the predetermined torque. Accordingly, the catch portion releases the transducer assembly to slip relative to the catch portion for limiting coupling of the transducer assembly with the acoustic waveguide to the predetermined torque.

摘要： An ultrasonic surgical instrument includes a first modular assembly including at least one operator input feature an ultrasonic transducer supported by the first modular assembly, and a second modular assembly configured to be removably coupled with the first modular assembly. The second modular assembly includes at least a portion of an end effector extending distally from a distal end portion of the second modular assembly. The instrument includes a mechanical lockout assembly configured to switch between at least an unlocked configuration and a locked configuration. In the locked configuration, the first modular assembly and the second modular assembly are partially coupled together such that the operator is physically prevented from activating the instrument using the operator input feature. In the unlocked configuration, the first modular assembly and the second modular assembly are completely coupled together and the operator is able to activate the instrument using the operator input feature.

摘要： Devices and methods for increasing rotational torque during end effector articulation are provided. In general, a surgical device can include an end effector configured to articulate. The end effector can be configured to move between different angular orientations relative to an elongate shaft of the device having the end effector at a distal end thereof. The elongate shaft and the end effector can be configured to be rotated relative to a handle portion of the device. The device can include at least one friction member configured to provide increased resistance to rotation of the elongate shaft and the end effector when the end effector is articulated as compared to when the end effector is not articulated. The at least one friction member can thus be configured to increase rotational torque when the end effector is articulated as compared to when the end effector is not articulated.

摘要： An ultrasonic instrument includes a housing, an ultrasonic transducer support by the housing, and an integrated usage indicator. The housing is configured to removably connect to a shaft assembly. The ultrasonic transducer is configured to be acoustically connected to a waveguide and operated a predetermined number of use cycles. The integrated usage indicator is operatively connected to the housing and includes a used state indicator. The used state indicator is configured to indicate to a clinician in a used state when the ultrasonic transducer has been operated at least the predetermined number of use cycles for limiting usage of the ultrasonic transducer to the predetermined number of use cycles.
