Abstract

Devices and methods are provided for stabilizing fasteners post-deployment. Devices and methods are also provided for facilitating ejection of surgical fasteners from a cartridge. Devices and methods are also provided for guiding surgical fasteners. Devices and methods are also provided for facilitating closing and clamping of an end effector of a surgical device. Devices and methods are also provided for securing fasteners and adjunct materials to tissue. Devices and methods are also provided for removably coupling a cartridge to an end effector of a surgical device. Devices and methods are also provided for locking a surgical device based on loading of a fastener cartridge in the surgical device. Devices and methods are provided for adjusting a tissue gap of an end effector of a surgical device. Devices and methods are also provided for manually retracting a drive shaft, drive beam, and associated components.

Claims

1. A method of attaching a staple cartridge to an end effector of a stapling device, comprising:

positioning a staple cartridge in a channel formed within a cartridge jaw of an end effector of a surgical stapling device, the cartridge jaw having an anvil pivotally coupled thereto, and the end effector including a shuttle that slides proximally from a first position to a second position in response to seating of the staple cartridge fully within the channel in the cartridge jaw, the shuttle preventing at least one of closure of the anvil and the cartridge jaw to engage tissue and firing of staples from the cartridge when the shuttle is in the first position and prior to the staple cartridge being fully seated within the channel in the cartridge jaw.

2. The method of claim 1, wherein movement of the shuttle from the first position to the second position causes a pin extending through a central aperture in the shuttle to move from a first position to a second position.

3. The method of claim 2, wherein positioning of the cartridge within the channel in the cartridge jaw moves the pin into one of the second position and a third position, the cartridge jaw and the anvil having a first clamp gap height when the pin is in the second position, and the cartridge jaw and the anvil having a second clamp gap height when the pin is in the third position, the second clamp gap height differing from the first clamp gap height.

4. The method of claim 2, wherein the pin in the first position prevents pivotal movement of the anvil and the cartridge jaw relative to one another.

5. The method of claim 2, wherein the pin in the first position prevents actuation of a firing mechanism to eject a plurality of staples from the staple cartridge.

6. The method of claim 2, wherein positioning the cartridge within the channel of the cartridge jaw sets a clamp gap between the cartridge jaw and the anvil.
