摘要： A surgical stapler including an anvil, a staple cartridge, and a buttress material removably retained to the anvil and/or staple cartridge. In various embodiments, the staple cartridge can include at least one staple removably stored therein which can, when deployed, or fired, therefrom, contact the buttress material and remove the buttress material from the anvil and/or staple cartridge. In at least one embodiment, the anvil can include at least one lip and/or groove configured to removably retain the buttress material to the anvil until deformable members extending from the surgical staple are bent by the anvil and are directed toward and contact the buttress material.

摘要： Surgical access devices having wound closure features incorporated as part of the device are provided. The devices allow suture to be inserted directly into the device and operated to close an opening through which the device is disposed as or shortly after the device is removed from the surgical site. Further, the wound closure features allow for various orientations of wound closure to be achieved by adjusting an angle at which the suture enters tissue surrounding the opening to be closed. Some of the wound closure features provided for include openings formed in both the housing and cannula of the surgical access device, multiple openings formed in one or both the housing and cannula, locations of the openings being adjustable or otherwise movable, and various flexible seals. Other features, as well as methods of closing an opening through which the surgical access device was disposed, are also provided.

摘要： A method for deforming a staple comprising a base, a first staple leg, and a second staple leg, wherein the base, the first staple leg, and the second staple leg are positioned within a common plane prior to being deformed, the method comprising positioning the first staple leg within a first cup of a staple pocket, the first cup comprising a first inner surface, applying a first compressive force to the first staple leg to bend the first staple leg toward the base and the second staple leg, contacting the first inner surface with the end of the first staple leg to bend the end of the first staple leg toward a first side of the base, and deforming the first staple leg such that the end of the first staple leg crosses a mid-line of the staple defined between the first staple leg and the second staple leg.

摘要： A method of surgical stapling that uses a surgical instrument operable to compress, staple, and cut tissue. The instrument includes a body, a shaft, and an end effector with a pair of jaws. A placement tip extends distally from one of the jaws of the end effector. The method includes positioning the end effector at a desired site for surgical stapling. The method also includes controlling one or more of the jaws of the end effector to place the end effector in an open position. The method also includes positioning the end effector such that tissue is located between the jaws. The method also includes clamping the tissue between the jaws by moving at least one of the jaws toward the other jaw. The method also includes advancing a firing beam of the apparatus from a proximal position to a distal position.

摘要： A modular surgical instrument is disclosed. The modular surgical instrument comprises a control interface, a shaft extending from the control interface, an end effector extending from said shaft, and a control circuit. The control circuit is configured to sense the electrical potential applied to the modular surgical instrument, determine if the sensed electrical potential is above a predetermined threshold, and adjust the operation of the modular surgical instrument when the sensed electrical potential exceeds the predetermined threshold.

摘要： 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.

摘要： Circular stapling instruments and anvil assemblies. The anvil assemblies may have collapsible anvil support members that may be inserted through an opening in a patient and then expanded to be attached to an anvil plate assembly that has a staple-forming surface thereon. The anvil support member is attachable to the anvil plate assembly in such a way that when the anvil assembly is coupled to the stapling head of a circular stapler, the staple-forming surface is in substantial registry with the staples supported in the stapling head. A variety of different anvil support members and anvil plate assemblies are disclosed.

摘要： A trocar assembly includes a cannula assembly, an obturator assembly, and a catch arm. The cannula assembly has a housing, a cannula, and a working channel defining a longitudinal axis from a proximal opening to a distal opening. The obturator assembly includes a proximal head, a distal tip, and a shaft extending therebetween. The catch arm is selectively moveable from a retracted position to a first and second deployed positions and is configured to releasably capture a suture thread. In the retracted position, the catch arm is positioned radially inward from the first deployed position. In the first deployed position, the catch arm is positioned radially outward from the retracted position. In addition, the catch arm is configured to be moved a predetermined distance from the first deployed position to the second deployed position and release the captured suture thread therefrom.
