  • 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.

  • Patent number: 10624667
    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: 10537382
    Abstract: Instruments and methods for providing selective surgical instrument trigger lockout are provided herein. In one embodiment, a surgical instrument can include a distal end effector, a proximal actuator portion, a first trigger, a second trigger, and a lock arm. The lock arm can be configured to move between a first position, in which it interferes with actuation of the first trigger, and a second position, in which it permits actuation of the first trigger. Further, actuation of the second trigger can be effective to move the lock arm from the first position to the second position. Actuation of the first trigger can therefore be prevented if the second trigger is not already actuated. Selective trigger lockout can be useful in a variety of instruments, including, for example, surgical instruments that grasp, seal, and transect tissue.

  • Publication number: 20190357964
    Abstract: A surgical instrument includes an end effector, a handle assembly, a trigger assembly, an input driving body, and a coupling body. The end effector includes a pair of jaws, a knife, and an RF electrode assembly. The input driving body drives the knife between the pre-fired position and the fired position when traveling between the first position and the second position. The engagement body of the trigger assembly drives the input driving body from the first position to the second position when the coupling body is in the engaged position. The input driving body returns to the first position when the coupling body is in the disengaged position. The coupling body moves from the engaged position to the disengaged position is response to the input driving body traveling from the second position to the third position such that the input driving body returns to the first position.

  • Publication number: 20190357963
    Abstract: A surgical instrument includes an end effector, a handle assembly, and a knife drive assembly. The end effector includes a pair of jaws, a knife, and an RF electrode assembly. The knife actuates between a pre-fired position and a fired position. An arm of the handle assembly is configured to pivot the second jaw between the open position and the closed position. The knife drive assembly includes an input assembly, a rotary assembly, and an output assembly. The input assembly travels a first proximal distance to rotate the rotary assembly. The rotary assembly rotates in response to travel of the input assembly along the first proximal distance to drive the output assembly a first distal distance to thereby actuate the knife from the pre-fired position toward the fired position. The first distal distance is greater than the first proximal distance.
