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.

The camming member has at least one notch, and in a second position the lockout member has at least one of the stop members positioned to interface with the at least one notch. The engagement between the stop member and the notch limits distal movement of the camming member. The clip follower actuates the lockout member when the clip follower advances to a predetermined clip in the clip stack.

In order to improve the fixing of the surgical clips in the housing member in a surgical clip cartridge with a housing member and with a plurality of C-shaped surgical clips stored therein, having two limbs connected to one another by a web, the housing member comprising a plurality of compartments each to receive a surgical clip, with a support face adapted to the contour of the surgical clip in each compartment, against which support face a respective surgical clip abuts with its inner face, with holding members arranged on the housing member, which can be pivoted from a holding position into a release position and, in the holding position, fix the surgical clip in its compartment and, in the release position, are removed from the surgical clip, it is proposed that openings are provided in the limbs, in which the holding members engage in the holding position.

Surgical clip appliers are provided including a channel assembly extending distally from a housing; a clip carrier disposed within the channel assembly and defining a channel and a plurality of windows therein; a plurality of clips slidably disposed within the channel of the clip carrier; a wedge plate reciprocally disposed within the channel assembly, the wedge plate being operatively connected to the handles and including a plurality of apertures formed along a length thereof; and a clip follower slidably disposed within the channel of the clip carrier and disposed proximally of the plurality of clips, the clip follower being configured and adapted for selective engagement with the windows of the clip carrier and the apertures of the wedge plate. The clip follower is configured and adapted to urge the plurality of clips, in a distal direction relative to the clip carrier, upon reciprocal movement of the wedge plate.

A surgical clip is provided for ligating or transecting tissue, such as vessels, other tubular ducts, and the like and a surgical clip applier device for delivering and applying the surgical clip to the tissue. The surgical clip can include a spine and opposed arms extending from the spine where the arms can define a clamping length. In a resting state, the clip can be biased to a closed position such that the ends of each opposed arm are disposed in proximity to each other. With such biasing, when applied to a tissue, such as with a surgical clip applier, the clip can exert a positive clamping pressure to the tissue along the clamping length to seal the tissue and limit passage of fluids, such as blood, from the tissue.

A method of applying a surgical clip, wherein the clip has a rigid portion with a pair of opposed first and second leg members having proximal and distal ends and a knee portion formed therebetween. The clip also has an apex with opposed ends joining the proximal ends of the first and second leg members, and a compliant portion formed on an inner surface of at least one of the first and second leg members. The method includes the step of placing the opposed first and second leg members around a tissue to be ligated, and deforming the opposed first and second leg members towards each other. The method further comprises releasing the first and second leg members to cause a separation of the first and second leg members, wherein the separation is less than the total of thickness of the compliant portion and the thickness of the tissue within the first and second leg members.

An apparatus for application of surgical clips is provided and includes a lockout system selectively engageable with a pusher bar to prevent the pusher bar from returning to a home position and to prevent a trigger from completing a full stroke when a plurality of clips are substantially exhausted. The apparatus may include a trip mechanism including a trip lever biased into contact with the pusher bar, wherein distal movement of the drive bar moves the trip mechanism until the trip lever engages a lip of the pusher bar and in turn distally moves the pusher bar. The apparatus may include a wedge plate including a distal end placeable between spaced-apart jaw members, wherein the wedge plate is moved proximally to withdraw the distal end thereof from between the jaw members when a drive channel is moved in a distal direction.
