SURGICAL FASTENERS, APPLICATORS AND METHODS FOR INSTALLING SURGICAL FASTENERS Russian patent published in 2014 - IPC A61B17/68 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, and can be used to feed surgical fasteners from an applicator. The applicator comprises a body, an elongated shaft, an ejection rod, an ejection rod release, a release trigger mounted on the body, and an ejection spring. The ejection rod release is configured to interact with the ejection rod to prevent its distal motion during at least one stage of the ejection cycle. The first end of the ejection spring is connected to the ejection rod. The second end of the spring is configured to be connected continuously to the release trigger and disconnected from it during the ejection cycle. The ejection cycle involves an initial stage, whereat the release trigger is in an open position and disconnected from an energy storage element. The ejection spring is at least partially compressed. At the stage of guiding travel, the ejection rod release is disconnected from the ejection rod to advance the ejection rod in the distal direction.

EFFECT: providing the feed of the surgical fasteners from the applicator.
