A surgical instrument, comprising: a housing defining a track including a longitudinal portion and an angled portion extending from the longitudinal portion； a first actuation assembly selectively actuatable to deploy a first component； a biasing member coupled at a first end thereof to the first actuation assembly； a pin coupled to a second end of the biasing member and slidably disposed within the track； and a second actuation assembly selectively actuatable to deploy a second component, the second actuation assembly coupled to the first actuation assembly such that actuation of the second actuation assembly also actuates the first actuation assembly, wherein the pin is maintained within the angled portion of the track when the first actuation assembly is actuated such that the biasing member applies a biasing force against actuation of the first actuation assembly, and wherein the pin is moved to the longitudinal portion of the track and slid therealong when the second actuation assembly is actuated such that the biasing member applies a reduced biasing force against actuation of the second actuation assembly.
