TISSUE THICKNESS COMPENSATOR COMPRISING FIBERS TO PRODUCE A RESILIENT LOAD |
摘要 |
A nonwoven compensator for an end effector of a surgical instrument can comprise a plurality of spring fibers dispersed throughout the nonwoven compensator. The nonwoven compensator can be positioned in the end effector such as adjacent to a deck surface of a fastener cartridge that is positioned in the end effector. When a fastener from the fastener cartridge is moved from an initial position to a fired position, the fastener can be configured to engage the nonwoven compensator. The fastener can compress a portion of the nonwoven compensator in a staple entrapment area defined by the fired staple. The spring fibers in the nonwoven compensator can comprise a resilient material and can be deformed when the fastener compresses a portion of the nonwoven compensator. Further, the nonwoven compensator can comprise non-spring fibers, a haemostatic material, and/or a homogenous absorbable polymer matrix.
