Specimen retrieval apparatus

A specimen retrieval apparatus, comprising:

• a housing having an elongated tubular member extending distally therefrom, the elongated tubular member defining a longitudinal axis;
• an end effector assembly coupled to a distal end of the elongated tubular member;
• a drive assembly operatively engaged to the elongated tubular member and configured for selectively translating the end effector assembly between a retracted position and an extended position;
• a trigger pivotably coupled to the drive assembly, the trigger being selectively depressible to incrementally move the end effector assembly from the retracted position to the extended position;
• a specimen retrieval bag releasably retained on the end effector assembly;
• an articulation mechanism operatively coupled to the end effector assembly, the articulation mechanism configured for selectively incrementally articulating the end effector assembly with respect to the longitudinal axis of the elongated tubular member between an aligned position, wherein the end effector assembly is generally aligned with the longitudinal axis, and an angled position, wherein the end effector assembly is disposed at an oblique angle relative to the longitudinal axis;
• and
• a rotatable actuator operably disposed on the housing, coupled to the drive assembly, and coupled to the articulation mechanism, the rotatable actuator being configured for:
• incremental translation distally along a translation axis relative to the housing in response to depression of the trigger for moving the end effector assembly from the retracted position towards the extended position;
• manual translation proximally along the translation axis relative to the housing to move the end effector assembly from the extended position towards the retracted position;
• and
• selective rotation about a rotation axis relative to the housing for articulating the end effector assembly with respect to the longitudinal axis, wherein the rotation axis is translated relative to the housing upon translation of the rotatable actuator along the translation axis relative to the housing.
