DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(8) In accordance with the invention, the best mode is presented in terms of a one or more of the disclosed embodiments, herein depicted within FIGS. 1 through 5. However, the disclosure is not limited to a single described embodiment and a person skilled in the art will appreciate that many other embodiments are possible without deviating from the basic concept of the disclosure and that any such work around will also fall under its scope.

(9) Further, those skilled in the art will recognize that other styles and configurations can be incorporated into the teachings of the present disclosure, and that the example configurations shown and described herein are for the purpose of clarity and disclosure and not by way of limitation.

(10) As used herein, the singular terms a, an, and the do not denote a limitation of quantity, but rather denote the presence of at least one (1), as well as a plurality of, the referenced items, unless the context clearly indicates otherwise.

(11) As used herein, the terms first, second, third, etc. are used as labels to describe various elements, features, and/or components, and are not intended to impose ordinal, positional, or hierarchical requirements on the referenced items, unless other indicated. For example, such terms may be used to distinguish one (1) element from another element.

(12) As used herein, relative terms such as front, rear, left, right, top, bottom, below, above, upper, lower, horizontal, or vertical are used to describe a relationship of one (1) element, feature and/or region to another element, feature and/or region as illustrated in the figures.

(13) Referring to FIGS. 1-5, disclosing a morcellated tissue apparatus (herein referred to as the apparatus) 10, where like reference numerals represent similar or like parts. The apparatus 10 provides a means to collect upon a mat 20b extraneous loose (e.g., morcellated) tissue resulting from the sectioning, cutting, or otherwise breaking up larger tissue specimens (e.g., organs) during a laparoscopic surgical procedure and to gather the mat 20b into a pouch 20c for extraction of the morcellated tissue.

(14) Referring now to FIGS. 1, 2, and 5, perspective views of the apparatus 10 configured as a mat 20b (e.g., in a layed-flat configuration), configured as a roll 20a, and configured as a pouch 20c, respectively, according to one (1) embodiment of the present invention, is disclosed. The apparatus 10 can be configured as a roll 20a (also referred to herein as a roll configuration 20a) to be inserted within a patient, as a substantially planar mat 20b (also referred to herein as a mat configuration 20b) to be arranged to cover a portion of a patient's bowel, and as a pouch 20c (also referred to herein as a pouch configuration 20c) containing tissue to be extracted from the patient.

(15) The mat 20b, as seen in FIG. 1, has a top 22 along an upper surface to receive any tissue sloughed off during the morcellation procedure, and a bottom 24 (FIG. 2) along a lower surface and in contact with any subjacent organ(s). The mat 20b is preferably composed of a generally square sheet of a pliable thermoplastic material and as such may be presented in a variety of colors and opacity ranges. The mat 20b is provided with a hem 42 that is formed by folding a peripheral edge 26 of the mat 20b back upon itself and securing the peripheral edge 26 to the top 22, for example, with an ultrasonic seal.

(16) Within the hem 42 is an encircling tunnel 44 for the disposition of a cinch string 48, as illustrated in FIG. 2. The cinch string 48 is preferably a thermoplastic monofilament configured to draw up the peripheral edges 26 of the mat 20b so as to form the pouch 20c, as seen in FIG. 5. The ends of the cinch string 48 enter and exit from the tunnel 44 through an aperture 46, preferably located at a corner 28 of the mat 20b. As one (1) example, the cinch string 48 may be of sufficient length to extend to the exterior of the abdominal cavity for eventual use.

(17) Disposed along a distal edge 34 and the two (2) lateral edges 36 of the mat 20b is a barrier 64 that is intended to prevent any tissue from rolling or sliding off of the mat 20b after having been deposited thereon. The bather 64 is configured to be a coil of wire 62 secured within a barrier cover 66 attached to the top 22 of the mat 20b, as depicted in FIG. 4. The coil diameter should be sufficient to present the desired obstacle to the departure of any tissue. The barrier cover 66 is preferably a layer of thermoplastic material similar to, or consistent with, the constituent material of the mat 20b.

(18) The advantage of coiling the wire 62 is to beneficially exploit the spring effect of the wire 62 in order allow the mat 20b to be extended from the roll 20a configuration illustrated in FIG. 3. The apparatus 10 is placed (e.g., configured) as the roll 20a having a rolled configured to be inserted through a fifteen millimeter (15 mm) cannula into the abdominal cavity in at least one (1) embodiment.

(19) As seen in FIG. 4, the bather cover 66 can be sliced open with a scalpel to expose the wire 62 for extraction of the wire 62 prior to drawing (e.g., configuring) the mat 20b into a pouch 20c. The removal of the wire 62 will facilitate the eventual collapse of the mat 20b by removing the tendency of the wire 62 to spread the mat 20b.

(20) Referring now to FIG. 5, a perspective view of the apparatus 10 configured as the pouch 20c for extraction according to one embodiment of the present invention, is disclosed. Subsequent to the complete removal of the wire 62 from the barrier cover 66, the cinch string 48 would be pulled to close the mat 20b into a pouch 20c. Additional manipulation of the apparatus 10 with forceps may be required to accomplish the successful completion of this procedure.

(21) The aperture 46 of the tunnel 44 may need to be elevated and steadied while the cinch string 48 is pulled in order to secure items within the apparatus 10. The top 22 of the mat 20b will be drawn into the interior 52 of the pouch 20c while the bottom 24 will be reconfigured to be an exterior 54 surface. All of the material previously disposed upon the top 22 will now be secured within the interior 52 and the pouch 20c can be extracted through the cannula.

(22) Those skilled in the art will recognize that other styles and configurations of the disclosed apparatus 10 can be easily incorporated into the teachings of the present disclosure, and only particular configurations have been shown and described for purposes of clarity and disclosure and not by way of limitation of scope.

(23) One embodiment of the disclosed method for utilizing the apparatus 10 includes the following steps: 1). acquiring a model of the apparatus 10; 2). inserting the roll 20a through a cannula into an abdominal cavity at a proper time in the procedure; 3). allowing the roll 20a to open into the mat 20b; 4). positioning the mat 20b to protect the bowel and receive any tissue sloughed off from the morcellation procedure; 5). slicing open the barrier cover; 6). retracting the wire 62; 7). manipulating the mat 20b to properly close into the pouch 20c by pulling the ends of the cinch string 48; and 8). extracting the pouch 20c from the abdominal cavity. The extracted morcellated tissue may be analyzed for diagnosis or discarded as required.

(24) The foregoing descriptions of specific embodiments have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit to the precise forms disclosed and many modifications and variations are possible in light of the above teachings. The embodiments were chosen and described in order to best explain principles and practical application to enable others skilled in the art to best utilize the various embodiments with various modifications as are suited to the particular use contemplated.
