Problems solved by technology

However, in some circumstances, end-effectors having such a linear configuration are somewhat difficult to use.
More particularly, for example, when the end-effector must be placed adjacent to or against a cavity wall, such as the thoracic cavity wall, for example, it is often difficult for the surgeon to position a jaw of the end effector behind delicate or fragile tissue which is proximal to and / or attached to the cavity wall.
Furthermore, even if the surgeon is successful in positioning a jaw behind the tissue, owing to the linear configuration of the end-effector, the surgeon may not be able to see the distal end of the end-effector.
However, owing to the amount of force that is typically transmitted through the flexible drive member, the drive member may buckle or otherwise deform in an unsuitable manner.

Embodiment Construction

[0069]As known in the art, it is often necessary to resect tissue from a patient after the tissue has become necrotic or cancerous, for example. Frequently, blood vessels within the tissue are transected as the tissue is being cut. As a result, blood may flow from the blood vessels and complicate the surgery or endanger the patient. Often, a surgical stapler is used to secure and compress several layers of tissue together in order to substantially close the blood vessels. For example, referring to FIG. 1, a surgical stapler, such as an endocutter, can include devices which staple and then cut the tissue. As a result, the blood vessels can be substantially closed by the staples before the tissue is cut, thereby reducing bleeding therefrom.

[0070]Referring to FIGS. 1 and 2, endocutters, such as endocutter 100, for example, typically include an end-effector 102, a handle portion 104 (FIG. 2), and a shaft 106 extending therebetween. End-effector 102 includes first jaw 108 and second jaw ...

Abstract

An end effector for a surgical stapler. Various embodiments include a channel configured to operably support a staple cartridge therein. A first tip portion is attached to or formed on a distal end of one of the channel and staple cartridge wherein the first tip portion may have a first upwardly extending curved outer surface. An anvil is movably coupled to the channel and is selectively movable between open and closed positions relative to the staple cartridge in response to opening and closing motions applied to the anvil. A second tip portion is attached to or formed on a distal end thereof. The second tip portion may have a second downwardly extending curved surface such that when the anvil is in the closed position, the second tip portion cooperates with the first tip portion to define a blunt end effector nose. In various embodiments, the end effector nose has a substantially paraboloid outer surface.
