A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and an elongate shaft extending therefrom with opposed jaws formed on a distal end thereof. The trigger is adapted to advance a clip to position the clip between the jaws, and to move the jaws from an open position to a closed position to crimp the clip positioned therebetween.

Methods and devices are provided for performing various procedures using interchangeable end effectors. In general, the methods and devices allow a surgeon to remotely and selectively attach various interchangeable surgical end effectors to a shaft located within a patient's body, thus allowing the surgeon to perform various procedures without the need to remove the shaft from the patient's body. In an exemplary embodiment, multiple end effectors can be introduced into a body cavity. The end effectors can be disassociated or separate from one another such that they float within the body cavity. A distal end of a shaft can be positioned within the body cavity and it can be used to selectively engage one of the end effectors. In particular, the device can be configured to allow each end effector to be remotely attached and detached from the distal end of the shaft. For example, a surgeon can actuate an actuation mechanism on the proximal end of the shaft to mate one of the end effectors to the distal end of the shaft without assistance from other tools and devices. After use of the end effector, the end effector can be released and another end effector can be remotely attached to the distal end of the shaft.

A lock suitable for use in a motor vehicle door has a rotary latch, a locking wedge, a pawl, a setting device, and a transmission device wherein the rotary latch cooperates with the locking wedge to be locked in a locking position by the pawl. Upon actuation of a manipulator, the setting device brings the pawl electrically at least into one opening position. The transmission device brings the pawl into its opening position by actuation of the manipulator over a displacement range which is greater than a displacement range of an electric unlocking.

The present invention provides methods and devices for placing a spinal fixation rod into a rod receiving opening in a spinal anchor and installing a fastener to secure the rod to the spinal anchor. In one embodiment, the system can include a cap having a bore extending therethrough, an elongate drive rod that is adapted to extend through the bore, and a fastener that is disposed on a distal portion of the drive rod. The cap can include a driving element that is adapted to cooperate with a complementary driving element disposed on the rod to form a driving mechanism. Actuation of the driver mechanism can be effective to advance the drive rod through the cap to thereby reduce a spinal rod into a rod receiving opening of the spinal anchor and install the fastener to secure the rod to the spinal anchor.

A key structure comprises a membrane circuit, a substrate, a cover and a press element. The membrane circuit comprises at least one first signal generator and a second signal generator. The substrate is disposed below the membrane circuit to support the membrane circuit. The cover comprises a body and at least one protrusion, wherein the protrusion is disposed on the body corresponding to the first signal generator. The press element is disposed on the second signal generator, wherein when force is applied on the cover, the protrusion presses the first signal generator.
