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.

Dependencies are inferred from the claim text.
