An apparatus for application of surgical clips to body tissue includes an actuator at least partially disposed within a body and longitudinally movable in response to actuation of a handle portion. The apparatus includes a jaw closure member positioned adjacent the first and second jaw portions to move the jaw portions to the approximated position and a rack having ratchet teeth connected to the actuator. The apparatus includes a pawl engaging a series of ratchet teeth and capable of preventing an inadvertent return of the actuator before full actuation of the apparatus. A clip pusher incrementally moves distally each time a clip is released from the apparatus. When the clip pusher reaches a predetermined distal point in a clip carrying channel, a feed bar is deflected to a second position to prevent retraction but not advancement of the actuator and thereby manipulates the pawl to engage the ratchet teeth.

An ultrasonic surgical instrument comprises a reusable housing including an internal transducer and an internal end effector rotation assembly. An exemplary rotation assembly is a ratchet and pawl assembly, which allows the transducer to rotate in a first direction but not in a second, opposite direction. The end effector, including an integral torque wrench, is attached to the transducer to form a single unit that is rotatable relative to the housing. The transducer attaches to a stationary cable via slip rings. The cable communicates with a generator, which provides electrical power to the transducer. The transducer converts the electrical power into ultrasonic vibrational energy, which is transmitted to the end effector.

Принадлежит: WARSAW ORTHOPEDIC INC

A surgical retractor includes a first member defining a longitudinal axis. The first member includes a blade disposed in spaced apart relation relative to the longitudinal axis and a grip surface. A second member has a blade disposed in spaced apart relation relative to the longitudinal axis and a grip surface. The grip surfaces are configured to be drawn together along the longitudinal axis such that the blades are engageable with tissue and connected with the grip surfaces such that the grip surfaces provide a tactile feedback of the tissue engagement. Systems and methods of use are disclosed.

A surgical instrument includes a handle assembly having an actuating rod extending therefrom, a rotating member, a release member, and a stop, the actuating rod translatable along a longitudinal axis defined therethrough. The rotating member is disposed within the handle assembly and is configured to operably engage the actuating rod via a cam and link arrangement. The release member includes a first catch configured to lock the rotating member against the force of an energy storage device in a first condition and release the rotating member to rotate in an opposite direction with the force of the energy storage device in a second condition. The stop is disposed on a peripheral edge of the rotating member and is configured to operably engage the first catch when the release member is disposed in the first condition to limit the rotational movement of the rotating member.
