Claim Text:
1. 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through a substantial portion of a circumference of the pocket, to a second closed position where the biasing member is withdrawn from the pocket; an elongate push rod with a distal end portion fixed to the biasing member and an opposite proximal end portion operatively engaged with a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 housing supports and encloses an engagement between the pinion gear and the push rod and an engagement between the plunger and the pinion gear, wherein the plunger is rotatable about its longitudinal axis, wherein the plunger comprises a ledge defined blindly along and in parallel with the longitudinal axis of the plunger, the ledge extends radially from a side surface of the plunger, and the housing comprises an elongate first slot configured to receive the ledge when the plunger is in a first rotational position, wherein sliding engagement between the ledge and the first slot allows a full range of motion of the plunger with respect to the housing, such that the biasing member may 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.
