Abstract

A loading unit (100) comprising a shipping member (200) is provided. The shipping member (200) is receivable on the distal end of the loading unit (100) in a first orientation to prevent movement of the pusher assembly (130) from the first position to the second position, and enables loading in the second orientation Detachment of the unit (100) from the surgical stapling device (10).

Description

technical field [0001] The present invention relates to a surgical stapling device comprising a replaceable loading unit. More particularly, it relates to a shipping member that prevents firing of a loading unit until the shipping member is disengaged from the loading unit and facilitates disengagement of the loading unit from a surgical stapling device. Background technique [0002] Circular anastomosis devices are commonly used to join tubular tissue segments via circular anastomosis. Typically, annular stapling devices include a loading unit for applying an annular array of staples to tissue. The loading unit is typically replaceable after firing, allowing re-use of the annular anastomotic device. During transport and connection of the loading unit to the annular anastomotic device, the pusher and blade assembly within the loading unit may become misaligned, preventing proper installation of the loading unit to the annular anastomotic device. Additionally, after firing...
