Surgical Stapling Apparatus

A system for performing an end-to-side vascular anastomosis, including an anastomosis device, an application instrument and methods for performing a vascular anastomosis. The system is applicable for performing an anastomosis between a vascular graft and the ascending aorta in coronary artery bypass surgery, particularly in port-access CABG surgery. A first aspect of the invention includes a vascular anastomosis staple. A first configuration has two parts: an anchor member, forming the attachment with the target vessel wall and a coupling member, forming the attachment with the bypass graft vessel. The anastomosis is completed by inserting the coupling member, with the graft vessel attached, into the anchor member. A second configuration combines the functions of the anchor member and the coupling member into a one-piece anastomosis staple. A second aspect of the invention includes an anastomotic fitting, having an inner flange over which the graft vessel is everted and an outer flange which contacts the exterior surface of the target vessel. A tailored amount of compression applied by the inner and outer flanges grips the target vessel wall and creates a leak-proof seal between the graft vessel and the target vessel. A third aspect of the invention has a flange to which the graft vessel attaches, by everting the graft vessel over the flange, and a plurality of staple-like members which attach the flange and the everted end of the graft vessel to the wall of the target vessel to form the anastomosis.

A surgical stapling instrument (1) comprises a body portion (2, 3), a handle (4) and a staple fastening assembly (8). The staple fastening assembly (8) includes a curved cartridge (10), which comprises at least one curved open row of staples, and a curved anvil (22), which is adapted to cooperate with the cartridge (10) for forming the ends of the staples exiting from the cartridge (10). The staple fastening assembly (8) is adapted to allow unobstructed access towards the concave inner faces of the cartridge (10) and the anvil (22). The cartridge (10) can be moved towards the anvil (22) from a spaced position for positioning tissue therebetween to a closed position for clamping the tissue. Preferably, a knife is contained within the cartridge (10) and is positioned such that there is at least one row of staples on at least one side of the knife.

A surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel. The surgical instrument can further comprise a cutting member configured to incise tissue positioned captured between the staple cartridge and the anvil and, in addition, means for stopping the cutting member prior to a distal end datum, wherein the distal end datum can be defined by the distal-most staple cavity in the staple cartridge. In such embodiments, the incision within the tissue may not extend beyond the portion of the tissue that has been stapled.

Systems, methods, and miniature instruments (e.g., 12, 30, 40, 50, and 102) are disclosed for minimally invasive surgical procedures. A miniature surgical instrument can be inserted directly into a body cavity (16) through a cannula (10, 118) in a way that a surgeon can insert his or her hand into the cavity (16) through a separate minimal incision and use the miniature instruments. A miniature surgical system can include: a cannula (10, 118) having a hollow body configured to receive a miniature surgical instrument (102) and a tether (13, 104) connected to the instrument; and a plunger (108) sized to engage a proximal end of the body and including a conduit (106) therethrough for receiving the tether. The system can also include the tether and the instrument. During use, the instruments can be quickly and safely removed from the body cavity to enable the surgeon to use his or her fingers, e.g., to manipulate tissue.

Systems methods and instruments for minimally invasive surgery

A device for retracting edges of an incision in a surface to form an opening including: a flexible, tubular skirt having an upper end, a lower end, and a channel therebetween; a ring connected to the lower end of the skirt for maintaining the lower end in an open configuration and defining an exit opening to the channel; and an inflatable collar connected to the skirt and surrounding the upper end. The ring is designed to fit through the incision and remain under the surface when it is oriented parallel to surface. The collar, when inflated, maintains the upper end in an open configuration and defines an entry opening to the channel. During use, the ring is inserted through the incision and the collar is inflated while remaining outside of the incision, thereby drawing the skirt against the edges of the incision and retracting the edges of the incision to form the opening. The retracting device can be included in a surgical access port, which further includes a flexible sleeve connected to at least one of the inflatable collar and the skirt, extending the channel from the exit opening of the skirt to an open end of the flexible sleeve distal to the skirt. The device can include a light source in the vicinity of the exit opening.

Surgical access port and laparoscopic surgical method

A lens warming and cleaning device (110, 210, 310, 410) is used to warm and clean the lens (14) and/or distal portion (16) of an optical instrument such as a laparoscope (10). The warming and cleaning device includes a heat conducting tube (114, 214, 314, 414) sized and shaped to receive the lens of the optical instrument, a heating pad (120, 220, 320, 420) thermally coupled to an exterior of the tube, and a cleaning member in the form of a sponge (116, 216, 316, 416) disposed within the tube such that when the lens of the optical instrument is inserted into the tube, the lens contacts the sponge. A moistening mechanism in the form of a squeeze bottle (118, 418) containing a saline solution can be in contact with the sponge so that a surgeon can squeeze the bottle to moisten the sponge.

An endoscope system according to the present invention is characterized by an imaging assembly that a user can alternatively attach to a first deployment assembly and to a second deployment assembly. The image assembly has a distal end configured for detecting image information and a proximal end configured for delivering the image information to a location remote from the imaging assembly distal end. The deployment assembly for deploying the imaging assembly includes a support member and a connecting member. The connecting member is carried on the support member and is removably and replaceably mountable with the imaging assembly housing for connecting the support member to the imaging assembly. According to a preferred embodiment of the invention, the support member includes a shaft member, a handle element connected to the proximal end of the shaft member for manual engagement of the deployment assembly, an articulating portion connected to the distal end of the shaft member and movable between undeflected and deflected positions for deflecting the tip of the imaging assembly, and a deflecting element. The deflecting element is attached in selected proximity to the distal end of the articulating portion for deflecting the articulating portion. The deployment assembly can include an imaging assembly guide element slidably and removably and replaceably mountable with the imaging assembly. Thus, an operator can use her hand to slidably extend the imaging assembly from the deployment means so as to position the imaging assembly's distal end in selected proximity to a target site.
