1. A medical instrument, comprising:
a handle;
an activation lever disposed on the handle, the activation lever being movable between a closed activation lever configuration and an open activation lever configuration by application of an external force to the activation lever;
a shaft mounted to and extending distally from the handle; and
an end effector disposed distally on the shaft, the end effector comprising a first jaw movable between a closed jaw configuration and an open jaw configuration, the first jaw being operatively coupled to the activation lever such that moving the activation lever from the closed activation lever configuration to the open activation lever configuration moves the first jaw from the closed jaw configuration to the open jaw configuration;
wherein the activation lever and handle include a track and a track follower configured to decrease an external force required to move the activation lever from the closed activation lever configuration to the open activation lever configuration as the activation lever moves from the closed activation lever configuration to the open activation lever configuration; and
wherein the first jaw is configured to releasably receive an occlusion clip.
