Device for driving surgical fasteners

摘要

A device for driving surgical fasteners into tissue such as the menisci of the knee. The device essentially consists of a tubular housing member through which a piston shaft passes. The piston shaft extends at a first end and terminates in a gripping knob which facilitates retraction of the piston from the housing, and contacts a fastening member at a discharge end to drive the fastener from the device. A pivotable latching member engages the gripping knob when the piston arrangement is retracted against the force of the spring, and pivots to release the piston arrangement to fire the fastener.
