TRIGGER-BASED TISSUE ANCHOR DEPLOYMENT

Abstract

Medical instruments and related actuation mechanisms are disclosed. In various examples, a medical instrument includes a handle and a suture lock configured to selectively secure a portion of a suture line relative to the handle. The suture lock is transitionable between a locked position, in which the suture line is fixed, and an unlocked position, in which the suture line is releasable, by way of a manually actuatable actuator associated with the handle. In some examples, a medical instrument includes a manually pressable trigger actuator carrying a first rack, a carrier including a second rack, and a pinion gear simultaneously engaged with the first and second racks to coordinate movement of the trigger actuator and the carrier. A drive rod is coupled to the carrier, and an instrument hub is detachably coupled to the drive rod to support operation of an associated medical instrument.
