A depth limiter that is configured to couple with first and second trocar cannulas having different diameters. The depth limiter includes first and second body portions. First and second body portions each include first and second gripping surfaces. The first and second body portions are pivotably coupled together and are movable between an open configuration and a closed configuration. In the open configuration, the first and second body portions are configured to allow for axial movement of the depth limiter relative to the first and second trocar cannulas. The first gripping surfaces of the first and second body portions are configured to restrict axial movement of the depth limiter relative to the first trocar cannula in the closed configuration. The second gripping surfaces of the first and second body portions are configured to restrict axial movement of the depth limiter relative to the second trocar cannula in the closed configuration.

Multi-diameter cannula depth limiter

A depth limiter that is configured to couple with a cannula of a surgical access device. The depth limiter includes first and second user contact portions and first and second biasing features. The first biasing feature includes a first resilient portion and a first gripping surface. The second biasing feature includes a second resilient portion and a second gripping surface. The first and second resilient portions are configured to move the respective first and second gripping surfaces from a fixed configuration to a movable configuration when the respective first and second user contact portions are actuated. In the fixed configuration, the first and second gripping surfaces collectively restrict axial movement of the depth limiter by directly contacting the cannula. In the movable configuration, the first and second gripping surfaces extend parallel to a longitudinal axis and allow for axial movement of the depth limiter relative to the cannula.

Disclosed is a surgical instrument with an end-effector adapted and configured to deliver a plurality of energy modalities to tissue at a distal end thereof. The energy modalities may be applied simultaneously, independently, or sequentially. A generator is electrically coupled to the surgical instrument and is configured to supply a plurality of energy modalities to the end-effector. In one aspect, the generator is configured to supply electrosurgical energy (e.g., monopolar or bipolar radio frequency (RF) energy) and ultrasonic energy to the end-effector to allow the end-effector to interact with the tissue. The energy modalities may be supplied to the end-effector by a single generator or multiple generators.

An apparatus includes an elongate body, at least one latch member, and a cartridge removal feature. The elongate body is sized and shaped to correspond with a deck of a surgical staple cartridge such that the elongate body is configured to cover a plurality of staple apertures of the surgical staple cartridge. The at least one latch member is configured to removably secure the elongate body to the surgical staple cartridge. The cartridge removal feature is integral with the elongate body. The cartridge removal feature defines a gap that is configured to receive a portion of the surgical staple cartridge. The cartridge removal feature is further operable to remove the surgical staple cartridge from a surgical stapler.

An end-effector and a surgical instrument including the end-effector are disclosed. The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and to electrically couple to a pole of an electrical generator. The clamp arm includes a clamp jaw, a cantilever electrode configured to electrically couple to an opposite pole of the electrical generator. The cantilever electrode is fixed to the clamp jaw at a proximal end and free to deflect at a distal end. The clamp arm includes control features to adjust a tissue path relative to the clamp arm to create a predefined location of contact.
