A surgical clip applier is provided that includes first and second jaws on a distal end of an elongate shaft, a clip advancing assembly extending through the shaft and configured to advance a distal-most clip from a plurality of clips in the shaft into the first and second jaws. The jaws have opposed inward facing surfaces, and each inward facing surface has a clip track defined therein for receiving and guiding legs of a clip into the first and second jaws. The clip track of at least one of the jaws has at least one deflectable clip retention member disposed therein and configured to apply a biasing force to a leg of a clip disposed within the jaws to thereby retain the clip within the jaws and maintain alignment of the clip with respect to the jaws. The clip track of at least one of the jaws may also have at least one recess or protrusion designed to be complementary to and mate with a protrusion or recess in a clip.

Clip retention for surgical clip applier

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 a 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. The surgical clip applier can include a variety of features to facilitate use of the device, including features to prevent misalignment of the jaws and clip therebetween, features to protect the jaws, and features to ensure proper closure of the jaws and clip therebetween.

Surgical clip applier

Various devices are provided for allowing multiple surgical instruments to be inserted through a single surgical access device at variable angles of insertion, allowing for ease of manipulation within a patient's body while maintaining insufflation. Safety shields and release mechanisms are also provided for use with various surgical access devices.

Surgical access device

A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.

Staple cartridge comprising a staple driver arrangement

A method of suturing a trocar path incision in a tissue of a patient with an obturator includes inserting the obturator through the tissue such that a shaft of the obturator extends through a tissue opening about the trocar path incision and a distal tip of the obturator is positioned within a cavity of the patient. The method also includes directing the suture via a suturing feature with the obturator inserted through the tissue in order to direct the suture relative to the tissue. Furthermore, the method includes closing the tissue opening about the trocar path incision with the suture.

Method of suturing a trocar path incision

An obturator configured for use with a trocar includes a head and a distally extending shaft configured to be received within a working channel of a trocar. The obturator further includes a distal tip configured to puncture tissue, first and second needle entrance ports each arranged on at least one of the head or the shaft, and first and second needle exit ports arranged on the shaft. The first and second needle entrance ports communicate with the first and second needle exit ports, respectively, to define respective first and second suture paths extending obliquely to the central axis. Each of the first and second suture paths includes at least one sealing element. In some examples, the obturator further includes at least one deployable member coupled to the shaft and configured to project radially outwardly in a deployed position.

Trocar obturator with transverse needle ports

A stapling assembly comprising an end effector movable from an open configuration to a closed configuration is disclosed. The end effector comprises an anvil and a staple cartridge comprising a first tissue-contact surface, a second tissue-contact surface stepped up from the first tissue-contact surface, an annular row of cavities, and a plurality of staples removably stored in the cavities. The anvil is configured to transition the staples from an unformed configuration to a formed configuration. Each staple comprises a crown, a first staple leg extending from the crown, and a second staple leg extending from the crown. The first staple leg and the second staple leg define a plane intersecting the crown in the unformed configuration. The first staple leg is bent toward a first side of the plane in the formed configuration. The second staple leg is bent toward a second side of the plane in the formed configuration.

Staple cartridge comprising a staple including deformable members

A staple cartridge assembly for use with a surgical stapling instrument is disclosed. The staple cartridge assembly comprises a plurality of staples and a cartridge body. The cartridge body comprises an elongate slot extending along a first longitudinal axis between a proximal end and a distal end of the cartridge body. The cartridge body further comprises a plurality of first staple cavities arranged in a first row. Each first staple cavity defines a first axis and comprises a first proximal end portion and a first distal end portion. The cartridge body further comprises a plurality of second staple cavities arranged in a second row. Each second staple cavity defines a second axis and comprises a second proximal end portion and a second distal end portion. Each first axis and each second axis are transverse to the first longitudinal axis. Each first axis is transverse to each second axis.

Surgical staple cartridge

A surgical stapling instrument () comprises a staple fastening assembly () in the distal region of said instrument, the staple fastening assembly () including a cartridge device () which comprises at least one closed row () of staples and defines a wavy distal end surface (), and an anvil () which defines a wavy proximal staple forming surface () substantially matching the distal end surface () and which is adapted to cooperate with the cartridge device () for forming the ends of the staples exiting from the cartridge device (), wherein the distal end surface () and the staple forming surface () have a globally wavy shape including two opposite peaks () and two opposite valleys () angularly spaced at about 90&#xb0; from the adjacent peaks () and in that said two-peaks-two-valleys wavy shape is formed by a stepped configuration of said surfaces ().
