Abstract

A trocar assembly for releasable engagement with an adapter assembly of a surgical stapling instrument includes a bearing assembly for distributing the axial load experienced by a drive member during tissue stapling. The bearing assembly is disposed within a housing between a flange of the housing and a flange of a drive member. The bearing assembly is configured to rotatably support the drive member and includes a thrust bearing, a rigid member, and a compressible member disposed between the thrust bearing and the rigid member. The compressible member includes a first compressed condition having a first thickness during a clamping stroke of the surgical stapling instrument and a second compressed condition having a second thickness during a stapling stroke of the surgical stapling instrument. The second thickness is less than the first thickness.
