It is disclosed an actuation mechanism for performing an action, where the actuation mechanism comprises: a first movable trigger assembly having a first trigger; a second movable trigger assembly have a second trigger, where the first trigger is movable independently with respect to the second trigger during a portion of movement of the first trigger and/or the second trigger; and a driving member in engagement with the first trigger assembly and the second trigger assembly, respectively, wherein, the first trigger assembly and the second trigger assembly are applied different mechanical advantages.

An ultrasonic scalpel, an energy instrument for surgical use, and a control method therefor; the scalpel including a handheld component and a control module; the handheld component provided with a trigger button. The trigger button is connected to an input terminal of the control module; the control module is electrically connected to an energy generating apparatus; and, if the trigger button is pressed, then the control module controls the energy generating apparatus to output ultrasonic energy, and, if the trigger button is released, then the control module controls the energy generating apparatus to stop outputting ultrasonic energy. In response to a first trigger signal triggered by an external switching action, each time the trigger button is pressed, the energy generating apparatus changes the current energy output state, the changed energy output state being maintained until the trigger button is pressed again.

An apparatus for insertion of a medical device in the skin of a subject is provided, as well as methods of inserting medical devices. Embodiments include removing a substantially cylindrical cap from an inserter to expose a substantially cylindrical sleeve, removing a cover from a substantially cylindrical container holding sensor components, and fitting the sensor components into the inserter.

A probe unit includes, a probe configured to treat a bone by ultrasonic vibration, a hollow sheath which surrounds the probe and which has a first portion at a small distance from a central axis, and a second portion at a greater distance from the central axis than the first portion, and a knob configured to rotate the sheath relative to the probe between a first position for insertion between the bone and a living tissue facing the bone so that the first portion is located between the bone and the living tissue and a second position for insertion between the bone and the living tissue so that the second portion is located between the bone and the living tissue.

A contact portion, provided in an exposed surface of the treating section, treats a treated object by a transmitted ultrasonic vibration while intruding into the treated object toward an intruding direction from a state being in contact with the treated object. An index portion is disposed on an anti-intruding direction side with respect to the contact portion in the exposed surface. The index portion becomes an index indicating an intruding amount of the contact portion into the treated object toward the intruding direction. The index portion includes index surfaces arranged in the intruding direction, and each of the index surfaces has an angle relative to the intruding direction which is different from the angle of the adjacent index surface.

A locking device arranged in an actuation unit of a surgical instrument which has a hollow shaft with the actuation unit arranged at a proximal end of the shaft and having a tool at the distal end of the shaft which can be actuated by an instrument insert which can be movably stored axially in the direction of a main instrument axis (A) in the shaft. The locking device has an engagement element and an actuation device with which the engagement element can be transferred from a release position into a locking position. The engagement element can be a locking bolt which longitudinal axis runs perpendicular to the main axis (A) of the instrument and which has an engagement section configured for engagement with the instrument insert at a first end and a guide section. The locking bolt can be moved in two directions of movement by the actuation device.

A surgical device includes a jaw assembly defining a first longitudinal axis and including a first jaw and a second jaw moveable relative to the first jaw; an elongated body defining a second longitudinal axis and coupled to a proximal end of the jaw assembly, wherein the jaw assembly is configured to articulate about an articulation axis transverse to the second longitudinal axis relative to the elongated body; and a handle assembly coupled to a proximal end of the elongated body and including at least one motor mechanically coupled to the jaw assembly and a control assembly including a first control button and a second control button, wherein actuation of the first control button moves the second jaw in approximation relative to the first jaw and actuating the second control button moves the second jaw away from the first jaw, and actuating the first and second control buttons moves the jaw assembly to a centered position in which the first and second longitudinal axes are substantially aligned, the handle assembly further includes an illumination member configured to output a light pattern indicative of a status of the surgical instrument.
