An ultrasonic surgical device comprises a handle assembly, a shaft assembly, and a removable transducer module. The transducer module includes a waveguide, a locking mechanism, and an electronics assembly including at least one button. The handle assembly includes a trigger assembly configured to actuate the button(s) of the electronics assembly when the transducer module is coupled with the handle assembly. The shaft assembly engages the waveguide of the transducer module and is disposed at the distal end of the handle assembly. The distal end of the shaft assembly includes a harmonic blade. When assembled with the handle assembly, the transducer module is capable of providing ultrasonic energy to the harmonic blade.

A mechanical end effector comprising at least two movable parts, wherein each of the movable parts is mounted on at least two supports, wherein a relative position of the movable parts with respect to each other is variable by changing the relative position of the supports with respect to each other, and wherein the supports of the movable parts comprise bendable members, wherein the bendable members are equipped with mechanical properties that arrange for flexing of the bendable members when a force applied by the supports of the movable parts exceeds a predefined value and the bendable members are embodied as cooperating bands to arrange that flexing of the cooperating bands provides a visual feedback to a user.

A surgical instrument includes a first power source and a second power source. The first power source is configured to deliver power to a surgical instrument at a first rate of discharge. The second power source is configured to deliver power to the first power source at a second rate of discharge. The first power source and the second power source are positioned within the surgical instrument. The first power source and the second power source are further configured to communicate with a control module. The control module may rely on power from the first power source to drive an end effector of the surgical instrument. The end effector may comprise a harmonic/ultrasonic blade, RF electrosurgical electrodes, powered cutting/stapling features, and/or various other types of components.

A surgical instrument comprises an articulable end effector; a drive shaft connected to the end effector that drives the end effector; an electric motor connected to the drive shaft that drives the drive shaft; a battery unit for supplying power to the electric motor; at least one sensor for sensing a status of the instrument; and an alphanumeric display located on the instrument and in communication with the at least one sensor. The alphanumeric display is for displaying alphanumeric characters that display visually to a user of the instrument a status of the instrument based on an input from the at least one sensor.

A forceps includes a housing defining a window and having an outer shaft extending therefrom. An end effector assembly disposed at a distal end of the outer shaft includes first and second jaw members including distal portions and proximal portions and movable between spaced-apart and approximated positions. An inner shaft is slidably disposed within the outer shaft such that, when the jaw members are disposed in the spaced-apart position, the inner shaft is disposed in a distal position. When the jaw members are moved to the approximated position, the proximal portions urge the inner shaft to a proximal position. An indicator member coupled to the inner shaft includes first and second indicators. The first indicator is visible through the window when the inner shaft is disposed in the distal position. The second indicator is visible through the window when the inner shaft is disposed in the proximal position.

Methods for treating tissue, and surgical assemblies and related methods are disclosed in which a single input is used to sequentially articulate two members. A surgical assembly includes an end effector, a base supporting the end effector, an input link movable relative to the base through a range of motion between a first configuration and a second configuration, and an actuation mechanism. The end effector includes a first articulated member and a second articulated member. The actuation mechanism drivingly couples the input link to the first articulated member within a first portion of the range of motion and drivingly coupling the input link with the second articulated member within a second portion of the range of motion so that a movement of the input link from the first configuration to the second configuration articulates the first articulated member and then articulates the second articulated member.
