摘要:
A tissue specimen retrieval device includes a housing having an outer shaft that extends distally therefrom. An end effector assembly is included that extends distally from the outer shaft in a deployed position. A first actuator is operably associated with the housing and actuatable to deploy and retract the end effector assembly. A drive shaft operably couples to the first actuator and includes a link disposed at a distal end thereof that operably couples to the end effector assembly. The drive shaft is movable via actuation of the first actuator from a first position wherein the end effector assembly and link are retracted within the outer shaft to a second position wherein the end effector assembly and link are fully exposed from the outer shaft. The link includes a biasing member that, once the link is fully exposed, articulates the end effector assembly to a position to engage tissue.
