Problems solved by technology

[0022] Although this method improves staple formation and reduces the force required to cut tissue and deploy staples, it also has a number of disadvantages
First, the surgeon needs to dispose of the entire anvil, channel, and cartridge after each firing, which increases manufacturing costs
Second, due to the fact that the anvil is actually clamped to the tissue relative to the fragile end effector, the instrument often does not clamp the target tissue securely
A third problem is that relative to the fragile end effectors, they are only reliable for firing moderately thick tissue, but are powerless for very thick tissue
Due to the increased anvil drag load on the knife, this method generally must generate higher deployment forces

Embodiment Construction

[0095] Figure 1 shows a surgical cutting and fastening instrument 10 capable of implementing the end effector configuration and / or staple cartridge configuration of the present invention. The surgical instrument 10 shown in FIG. 1 includes a handle 6 , a shaft assembly 8 and an articulating end effector 300 pivotally connected to the shaft assembly 8 at an articulation pivot 14 . In various embodiments, the control handle houses a drive motor 600 and a controller system, generally indicated at 610, for controlling the opening and closing of the end effector 300, as well as controlling the cutting and stapling of tissue held within it. . An articulation control 16 may be provided adjacent to the handle 6 to effectuate rotation of the end effector about the articulation pivot 14 . The handle 6 of the instrument 10 may include a closing trigger 18 and a firing trigger 20 for articulating the end effector 300 . The illustrated end effector 300 is preferably spaced from the handl...

Abstract

A disposable staple cartridge for a surgical cutting and fastening instrument. Various embodiments include a disposable anvil that is supported relative to the cartridge body and movable between open and closed positions. At least one tissue stop is provided on the disposable anvil for orienting the tissue to be cut and stapled relative to the staples supported within the cartridge body. Other embodiments relate to end effectors for surgical cutting and fastening instruments that can be used in connection with a plurality of staple cartridge bodies that each have a common length but which may different lengths of staple lines.
