摘要： A bipolar surgical instrument for fusing tissue includes first and second grasping members each having an end effector assembly attached at a distal end thereof. Each end effector assembly including a first jaw member with an active electrode disposed thereon and a second jaw member with a dielectric member disposed thereon. The first and second jaw members of each end effector are disposed in substantial opposing relation relative to one another and are movable from a first spaced position relative to one another to a second closer position for grasping tissue. Each active electrode is operably connected to an electrosurgical energy source. A surgical crimping tool is included and is selectively positionable to mechanically engage and crimp the active electrodes of the grasping members in a juxtaposed, side-by-side manner relative to one another prior to electrosurgical activation to fuse tissue into a unified tissue mass.

摘要： An endoscopic bipolar forceps includes a housing having a shaft affixed thereto, the shaft including jaw members at a distal end thereof. The shaft includes a longitudinal axis defined therethrough and the jaw members are adapted to connect to a source of electrosurgical energy such that the jaw members are capable of conducting energy through tissue held therebetween to effect a tissue seal. The forceps also includes a drive assembly which moves the jaw member relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for manipulating tissue. A movable handle is included which is rotatable about a pivot to force the drive assembly to move the jaw members between the first and second positions. The pivot is located a fixed distance above the longitudinal axis. A knife assembly is also included which has a movable knife bar having a generally t-shaped proximal end dimensioned to operatively engage a corresponding slot defined within the housing, the slot being dimensioned to guide the movement of the knife bar during translation thereof.

摘要： An endoscopic bipolar forceps includes a housing having a shaft affixed thereto, the shaft including jaw members at a distal end thereof. The forceps also includes a drive assembly which moves the jaw member relative to one another for manipulating tissue and a knife assembly for cutting tissue disposed between jaw members. The forceps also includes a knife lockout mechanism operatively connected to the drive assembly. Movement of the drive assembly moves the knife lockout mechanism from a first orientation in obstructive relationship with the knife bar to prevent movement thereof to a second position which allows selective, unencumbered movement of the knife assembly to cut tissue disposed between the jaw members.

摘要： An end effector assembly for use with an instrument for sealing vessels and cutting vessels includes a pair of opposing first and second jaw members which are movable relative to one another from a first spaced apart position to a second position for grasping tissue therebetween. Each jaw member includes a pair of spaced apart electrically conductive tissue contacting surfaces which each have an insulator disposed therebetween, the conductive surfaces are connected to an electrosurgical energy source. The first jaw member includes an electrically conductive cutting element disposed within the insulator which extends towards the second tissue contacting surface to create a gap therebetween. The cutting element is inactive during the sealing process while the two pairs of electrically conductive surfaces are activated to seal tissue. During the cutting process, the cutting element is energized to a first potential and at least one electrically conductive tissue contacting surface is energized to a different potential to effect a tissue cut through the tissue held between the jaw members along the already formed tissue seal.

摘要： Methods and apparatus are provided for a composite structural material. A non-solid composite section that is filled with a structural foam that reduces the weight of the composite structural material. A solid composite section that is coupled to the non-solid composite section. The solid composite section is an area for structural attachment for the composite structural material. A region adjoining the non-solid composite section to the composite section is radiused to reduce stress when the structural foam is bonded to the region. The radius in the region prevents delamination and cracking of the structural foam when a load is placed on the composite structural material.
