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.

An ultrasonic surgical instrument and method of assembly with a predetermined alignment includes first and second modular assemblies and an electrical lockout. The first modular assembly includes at least a portion of an end effector configured to manipulate a tissue. The second modular assembly includes a transducer power circuit and an activation switch electrically connected to the transducer power circuit. The electrical lockout is electrically connected to the transducer power circuit and configured to inhibit the activation switch from powering the ultrasonic transducer with the first and second modular assemblies misaligned from the predetermined alignment such that the first and second modular assemblies are in a locked-out state. The electrical lockout is further configured to allow the activation switch to power the ultrasonic transducer with the first and second modular assemblies in the predetermined alignment such that the first and second modular assemblies are in an operational state.

Electrical lockout for ultrasonic surgical instrument

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.

Aspects of the present disclosure are presented for a single surgical instrument configured to grasp, seal, and/or cut tissue through application of therapeutic energy, and also detect nerves through application of non-therapeutic electrical energy. A medical device may include two jaws at an end effector, used to apply therapeutic energy and to perform surgical procedures. The therapeutic energy may be in the form of ultrasonic vibrations or higher voltage electrosurgical energy. One of the jaws may be configured to cut tissue through application of the blade. In addition, one or both of the two jaws may be configured to apply nontherapeutic energy for nerve stimulation probing. The application of therapeutic energy may be disabled while the nontherapeutic nerve stimulation energy is applied, and vice versa. The nontherapeutic nerve stimulation energy may be applied to the use of one or more probes positioned near one or both of the jaws.

A depth limiter configured for use with a surgical cannula includes an annular base having a boss that extends about a longitudinal axis and has a boss lumen configured to receive the surgical cannula. A latch arm coupled with the annular base overlies the boss and includes an arm opening configured to align with the boss lumen to receive the surgical cannula. The latch arm is movable relative to the annular base between a release position and a lock position. In the release position the arm opening is positioned coaxially with the boss lumen such that the latch arm is configured to permit longitudinal movement of the depth limiter along the surgical cannula. In the lock position the arm opening is positioned non-coaxially with the boss lumen such that the latch arm is configured to inhibit longitudinal movement of the depth limiter along the surgical cannula.

An ultrasonic surgical instrument that includes an ultrasonic transducer, a handle assembly supporting the ultrasonic transducer, a clamp arm assembly, and a mechanical lockout assembly. The handle assembly includes a housing and an ultrasonic blade acoustically coupled with the ultrasonic transducer. The clamp arm assembly includes a clamp arm. The mechanical lockout assembly is configured to switch between at least an unlocked configuration and a locked configuration. In the locked configuration, the handle assembly and the clamp arm assembly are not completely coupled together and the operator is physically prevented from activating the instrument using an operator input feature. In the unlocked configuration, the clamp arm assembly and the shaft assembly are completely coupled together and the operator is able to activate the instrument using the operator input feature.

An apparatus includes a handle assembly, an end effector, a firing assembly, and a lockout assembly. The handle assembly includes first and second arms and a latching lever. The end effector includes first and second jaws and a staple cartridge. The firing assembly is configured to actuate from a pre-fired proximal position toward a distal position in order to staple and sever tissue captured between the first jaw and the second jaw. The lockout assembly is configured to prevent distal translation of the firing assembly in a locked configuration and allow distal translation of the firing assembly in an unlocked configuration. The latching lever is configured to actuate the lockout assembly from the locked configuration to the unlocked configuration in response to the latching lever pivoting the second jaw from a partially closed configuration to a fully closed configuration while the firing assembly is in the pre-fired proximal position.
