Surgical bag device and remote operating mechanism

A surgical bag device, comprising:

• a flexible material forming a bag with side and bottom seams defining a volume therein and an open top portion defining an aperture to allow access into the volume, the open top comprising a pocket disposed along substantially along an entire outer circumference of the open top;
• an elongate biasing member disposed in conjunction with the pocket and translatable between a first open position where the biasing member extends through a substantial portion of a circumference of the pocket, to a second closed position where the biasing member is withdrawn from the pocket;
• an elongate push rod with a distal end portion fixed to the biasing member and an opposite proximal end portion operatively engaged with a movable plunger within a housing, wherein the push rod is translatable as urged by the plunger such that the push rod is extendable to a distal position directing the biasing member into the open first position, and the push rod is translatable to a proximal position that urges the biasing member into the second position,
• wherein the push rod comprises a plurality of longitudinally spaced teeth disposed thereon, which are meshingly engagable with a plurality of teeth from a corresponding first set of teeth of a pinion gear, wherein the proximal portion of the push rod is configured to travel along an arcuate path within the housing for engagement between the teeth of the push rod and the first set of teeth of the pinion around a substantial portion of a circumference of the pinion.

• wherein the plunger comprises a ledge that extends along a length of a distal portion thereof, and the housing comprises a recess disposed therein to receive the ledge when the plunger is in a first rotational position with respect to the housing, wherein the recess is sized to allow for a full range of motion of the plunger with respect to the housing for the biasing member to translate between the first and second positions,
• wherein the ledge does not extend within the recess within the housing when the plunger is rotated to a different second rotational position, wherein rotation of the plunger to the second rotational position prevents the plunger from moving distally with respect to the housing.
