Laparoscopic procedures are frequently performed in patients (humans or mammals) to remove or modify a patient's tissue or anatomy in a minimally invasive manner, which allows for achievement of the clinical goal of the procedure while limiting the amount of surgical cutting or other trauma to the patient normally associated with open surgery. Laparoscopic procedures are normally associated with multiple small incisions made into the patient wherein tools may be passed through the small incisions to the surgical field through ports that are placed at each incision. Often it is clinically necessary to remove tissue from a patient during the procedure, which is placed into a surgical bad disposed at the surgical site for receipt of the tissue to be removed. The subject disclosure relates to surgical bag devices that are remotely operated and are configured to be used through or in conjunction with laparoscopic ports, or through open surgery.
A first representative embodiment of the disclosure is provided. The first embodiment includes 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 comprises a pocket disposed along substantially along an entire outer circumference of the open top. An elongate biasing member is 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through a substantial portion of a circumference of the pocket, to a second closed position where the biasing member is withdrawn from the pocket.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 is 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. 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 the first position 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 basing member to translate between the first and second positions.
A second representative embodiment of the disclosure is provided. The second embodiment includes 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 comprises a pocket disposed along substantially along an entire outer circumference of the open top. An elongate biasing member is 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 is 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. The push rod comprises a plurality of longitudinally spaced teeth disposed thereon, which are meshingly engageable with a plurality of teeth from a corresponding first set of teeth of a pinion gear.
Advantages of the present disclosure will become more apparent to those skilled in the art from the following description of the preferred embodiments of the disclosure that have been shown and described by way of illustration. As will be realized, the disclosed subject matter is capable of other and different embodiments, and its details are capable of modification in various respects.

Turning now to
The housing 20 may be formed from two clamshell halves 20a, 20b (
The housing 20 may include a first track 25 for slidably supporting the plunger 70 and a second track 26 for slidably receiving the push rod 30. In some embodiments, the first track 25 is disposed within the first clamshell half 20a, and the second track 26 is disposed within the second clamshell half 20b. The first track 25 may be substantially straight, while the second track 26 may include an arcuate portion 26a and a straight portion 26b. The arcuate portion 26a is formed with a radius just larger than the radius of the first wheel 52 of the pinion 50 and surrounds a substantial portion of the circumference of the pinion 50, such as 90, or 120, or 150, or 180 degrees of arc length (or any other suitable arc length) to provide for a mesh between a substantial number of teeth 54 of the first wheel 52 of the pinion 50 and a corresponding teeth 36 of the push rod 30 (each discussed in additional detail below) to cause the push rod 30 to translate within the second track 26 and the sheath 28 when the pinion 50 rotates. In some embodiments, the arcuate orientation of the second track 26 allows for a substantial potential translation distance of the push rod 30, while minimizing the size of the housing 20 (than would be necessary if the second track 26 were straight).
The first track 25 receives and slidably supports the plunger 70 to maintain one or more teeth 74 of the plunger 70 meshed with a corresponding number of teeth 58 the second wheel 56 of the pinion 50. In some embodiments, the housing 20 is sized to maintain the distal end portion 71 of the plunger completely therein throughout the complete range of translation of the plunger 70 with respect to the housing 20, while in other embodiments, the distal end portion 71 of the plunger 70 may extend into the sheath 28 as the plunger 70 is translated toward and reaches the second position (
The pinion 50 includes a first wheel 52 and a coaxial second wheel 56 that are fixedly mounted together and rotate simultaneously along a single axis 59. The first and second wheels 52, 56 each have a plurality of teeth 54, 58 that are disposed consistently along the outer circumference of each wheel. As discussed above the teeth 58 of the second wheel 56 are configured to mesh with corresponding teeth 74 disposed upon the plunger 70 and the teeth 54 of the first wheel 52 are configured to mesh with teeth 36 disposed upon the arcuate proximal end portion 34 of the push rod 30.
In some embodiments and as best shown in
As shown in
In some embodiments, the distal end portion 71 of the plunger 70 may include one or both of first and second cutouts 77a, 77b. As shown in
As discussed above, range of distal motion of the plunger 70 is constrained when in the third configuration due to the engagement of the distal tip 78a of the ledge 78 and the distal end of the second elongate recess 24b. The third configuration of the plunger 70 may be substantially opposite from the first configuration of the plunger 70 (e.g. about 180 degrees of rotation apart), where the ledge 78 travels within the first elongate recess 24a in the housing 20 for full travel of the plunger 70 therewithin, which, as mentioned above, allows for full opening of the open top 101 of the bag 100. In some embodiments, the plunger 70 may be rotatable to a second configuration between the first and third configurations, as shown in
In some embodiments, the device 10 may be configured such that the plunger 70 may include both the ledge 78 that extends within one of the respective first and second elongate recesses 24a, 24b when the plunger 70 is in the first and third configuration, respectively, and may include one or both of the of the first and second sets of teeth 74, 75 for meshing with the teeth 58 of the second wheel 56 of the pinion 50, for transmitting the input force of the plunger 70 to the push rod 30 for opening or closing the open top 101 of the bag 100. In other embodiments, the device 10 may configured such that the plunger 70 does not include the ledge 78, and the rotational position of the plunger 70 may be fixed with respect to the housing 20 for continuous engagement with the second wheel 56 of the pinion 50. In still other embodiments, the plunger 70 may include the ledge 78 or other similar structure that is engagable with first and second elongate recesses 24a, 24b when in the first and third configurations (and may also not mate with a corresponding recess when the in the intermediate second position) to selectively limit the translation of the plunger 70 with respect to the housing 20 while the motion (and force) of the plunger 70 is ultimately transmitted to the push rod 30 (or similar structure movable within the sheath 28) to open and close the bag 100 through another type of transmission mechanism.
With reference to
The biasing member 90 may be an elongate wire, sheet, bar, or the like, and includes two extended end portions 91 and a central portion 92 that is threaded through a hole 33 disposed in the distal end portion 32 of the push rod 30. The opposite end portions 91 of the biasing member 90, and the majority of the remainder of the biasing member 90 up to the central portion 92 are disposed through opposite sides of the pocket 101 when the bag 100 is in the open position, as shown in
The suture 98 is an elongate member that is threaded through the pocket 101, and opposite ends of the suture 98 may be connected to the opposite end portions 91 of the biasing member 90. Accordingly, as can be appreciated with reference to
