A more complete appreciation of the invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawing; it being understood that the drawings contained herein are not necessarily drawn to scale; wherein:
Referring to
At least a portion of the drape (12) of the present invention may be composed of one or more fluid impervious materials designed to deflect fluids from the surgical workspace as well as from the body of the patient before, during, and after a surgical procedure. A portion of the drape may be composed of non-woven fabrics such as polyester-wood pulp hydro-entangled non-woven fabric treated with fluorocarbons to enhance repellency, such as Fabric 450® from Johnson & Johnson Medical, Inc., and SONTARA® from Dupont, and Tiburon™ from Ahlstrom.
The drape (12) of the present invention has a lower surface (12L) for engaging the skin of the patient and an upper surface (12U) containing one or more adhesive portions (16). In one embodiment, the upper surface (12U) of the drape contains a plurality of Velcro® brand adhesive strips/areas, Micro Velcro (a.k.a. Hook 830) strips/areas, or other suitable adhesive materials. Such adhesive portions (16) may be arranged upon the upper surface (12U) of the drape (12) in any suitable fashion. In one embodiment, the adhesive portions (16) are arranged in a generally circumferential configuration upon the upper surface of the drape and around the drape opening (12F) in order to provide medical personnel with multiple adhesive options prior to and during surgical procedures, as discussed further below.
Referring to
The elastic stays of the present invention may also provide an adhesive portion (18A) capable of releasably attaching to the adhesive portion(s) (16) of the medical drape (12). In one embodiment, Velcro® brand adhesive strips (or areas) are applied to the upper surface (12U) of the drape as well as to the adhesive portion (18A) of each elastic stay (18). In preparing for surgery, medical personnel need only engage tissue to be retracted (14T) with the hook portion (18H) of the elastic stay, pull back the tissue to the desired position, then engage the adhesive portion of the elastic stay (18A) with an adhesive portion (16) upon the upper surface (16U) of the drape (12). In one embodiment, each elastic stay may be equipped with a pull tab (18P) at its distal end suitable for grasping by medical personnel during elastic stay orientation and removal.
The unique configuration of the surgical system (10) provided by the present invention allows medical personnel to gently and effectively pull back tissue (14T) in preparation for, and during, surgical procedures. Further, the elastic capabilities of the elastic stays of the present invention allow medical personnel to adjust the amount of tension applied to retracted tissue during surgical procedures, as illustrated by arrow (20).
In one embodiment, the drape of the present invention also provides one or more enclosures (22) for receiving surgical instruments (22I). In one embodiment, the enclosures of the present invention are composed of one or more heat resistant materials so as to allow for the insertion of warm instruments into the enclosures without adverse effects to the patient or to the drape.
During gynecological and/or rectal procedures, body fluids may be expelled during surgery, potentially subjecting medical personnel to slippery and/or untidy conditions. As such, the drape of the present invention may also be equipped with one or more pouches (24) designed to receive body fluids during a surgical procedure. In one embodiment, the pouch of the present invention may be positioned at or below the rectal area (14R) of the patient in order to efficiently collect any such fluids.
The unique drape of the present invention may also provide a removable rectal flap (26) designed to cover the rectal area (14R) of a patient (14) during surgical procedures. In one embodiment, the rectal flap (26) is equipped with one or more adhesive portions (26A) in order to allow for the releasable attachment of the flap to one or more adhesive portions (16) of the drape. The adhesive portions of the rectal flap (26) may also utilize Velcro® brand adhesive strips (or areas) in order to allow for quick attachment to and removal from the drape. The rectal flap (26) may also be composed of a transparent adhesive, as discussed below.
The incorporation of one or more adhesive upper surfaces, such as a Velcro® releasable type of adhesive, provides a number of advantages over known drape designs. In one embodiment, the Velcro® areas pad the perimeter of the wound site to allow the surgeon to comfortably rest his or her hands against the margins of the wound during an operation while also providing a retraction attachment point for elastic stays, an attachment point for grasping member(s), an attachment point for instrument bag(s), an attachment point for one or more retractor plate arrangements, and an attachment point for one or more leg straps. These features of the present invention allows any number of instrumentalities to be conveniently placed, relocated and/or interchanged, in a cost-effective manner.

The retaining portions of the present invention may utilize any form, type, or, number of engaging members. Such engaging members may include, but are not limited to, clamping devices that may or may not include teeth, one or more slotted section(s) capable of engaging elastic tails through compressive and/or interlocking force which further may utilize offsetting tail force vectors to promote adhesion of the grasping member(s); and/or one or more adhesives which may or may not be releasable as would be apparent to one or ordinary skill in the art in light of the disclosure herein.
The grasping member(s) of the present invention may be permanently affixed to the upper surface of the drape via any suitable mounting method and/or simply affixed to the drape via the retaining members, as described further below. Grasping members suitable for use with the present invention may include clips, hooks, clasps, or any other member capable of holding one or more elastic stays under tension. The unique configuration of the present invention allows medical personnel to gently and effectively pull back tissue (14T) in preparation for, and during, surgical procedures. Further, the elastic capabilities of the elastic stays of the present invention allow medical personnel to adjust the amount of tension applied to retracted tissue during surgical procedures.
Referring to
In one embodiment, the interlocking members of the present invention are capable of creating an interference fit for securing the drape or one or more elastic stays to the grasping member. The interlocking members of the present invention may comprise any number of structural configurations. In one embodiment, the interlocking member may have an angled portion (19G) capable of providing increased gripping force on the drape or elastic stay as tension is increased on the opposite end of the grasping member. Such tension may also be provided by an elastic tail secured within one or more tapered slots. In one embodiment, a release tab (19T) may be provided capable of releasing the drape from the grasping member. In another embodiment, the grasping member may be permanently attached to the drape. In one embodiment, the grasping member may mechanically interlock with the tail of an elastic stay with the interlocking structure and use other methods to attach to the drape.
Referring to
The present invention may also utilize one or more transparent adhesives (16T). In one embodiment, at least a portion of the lower fenestration (12FP) is covered by a transparent adhesive. The transparent adhesive allows the surgeon or other medical personnel to view the patient (14) through the adhesive. This feature of the present invention is particularly useful in posterior procedures, such as the posterior intra-vaginal slingplasty (PIVS) procedure. To illustrate, many posterior procedures require an incision measured three (3) centimeters lateral and three (3) centimeters inferior to the anus (14R) of the patient. In one embodiment, a transparent adhesive is utilized upon a portion of the lower fenestration in order to allow the surgeon to make incisions using the patient's anus as a reference point.
In one embodiment, the present invention provides a transparent adhesive (16T) upon a portion of the lower fenestration. The transparent adhesive also protects the surgical area from unsanitary conditions caused by accidents arising from the patient's posterior area. It should be understood by one of ordinary skill in the art that a transparent adhesive may be applied to any number of areas upon the surgical drape of the present invention according to any number of configurations. For example, it may be useful to provide a surgical drape having a transparent portion (16T) for overlay over the head of the patient. This feature of the present invention allows the patient to look upwardly through the drape if the patient is awake, while also allowing the surgeon or other medical personnel to observe the patient's conditions should he or she be placed under anesthesia during the procedure. In one embodiment, the present invention may utilize Tegaderm® brand transparent adhesive, manufactured by 3M corporation.
In one embodiment, the surgical drape of the present invention provides an upper fenestration (12FA) designed to facilitate surgical access to the chest and/or abdominal area of the patient (14). In one embodiment, the lower fenestration (12FP) and the upper fenestration (12FA) form a center portion (12C) there-between. In one embodiment, the center portion comprises a relatively thin strip of drape material containing at least one adhesive portion (16).
In one embodiment, the upper fenestration of the present invention has an oval or generally circular configuration. Adhesive portions may be positioned upon the upper surface of the drape in any suitable fashion. In one embodiment, adhesives (16) may be positioned laterally along the sides of the drape so as to facilitate the placement and retention of various cords (P) required to operate surgical devices. This feature of the present invention allows the surgeon or other medical personnel to work without concern for “dangling” power or vacuum cords near the surgical area. The upper fenestration may be covered in Tegaderm completely or partially. In one embodiment, the Tegaderm may cover the lateral portions of the upper fenestration to allow fiducial marker identification and instrument insertion.
As described above, the surgical system of the present invention may provide one or more pockets (22) and/or sub-pockets (22P) of varying sizes for receiving medical devices and/or accessories. In one embodiment, each pocket/sub-pocket arrangement is interchangeable in that they may be attached and removed at the discretion of the surgeon. In one embodiment, this is accomplished by providing one or more adhesive areas to each pocket/sub-pocket combination. In one embodiment, adhesives may be positioned upon the side areas (12S) of the surgical drape in order to facilitate attachment and removal of any number of pocket/sub-pocket combinations. In one embodiment, the side areas (12S) of the surgical drape of the present invention are ideally suited to rest upon the patient's outstretched legs during a posterior surgical procedure.
During gynecological and/or rectal procedures, body fluids may be expelled during surgery, potentially subjecting medical personnel to slippery and/or untidy conditions. As such, the drape of the present invention may also be equipped with one or more pouches (24) designed to receive body fluids during a surgical procedure. The pouch of the present invention may be positioned at or below the rectal area (14R) of the patient or laterally along the upper fenestration edges in order to efficiently collect any such fluids. In one embodiment, the pouch provides a mesh area (24M) for retaining large particles of biological waste generated during surgical procedures. The pouch may also provide a valve (24V) or spigot through which waste products may easily be drained after surgical procedures. In one embodiment, the valve or other drainage aid may be located at the bottom portion of the pouch such that gravity assists the surgeon in draining waste fluids.

In operation, a first end (28A) of the surgical flap may be releasably attached to or affixed to the center portion (12C) of the upper surface of the drape using the adhesive described above. In turn, the second end (28B) may be releasably attached or affixed to another adhesive portion of the drape such that one of the fenestrations (12FA or 12FP, respectively) is covered. In one embodiment, adhesive (16) may be positioned upon both the upper and lower surfaces (28U and 28L, respectively) of both ends (28A and 28B, respectively) of the surgical flap (28). This feature of the present invention allows the surgical flap to pivot about axis (A) in order to allow for coverage of the upper fenestration or the lower fenestration, depending on the particular needs of the surgeon. In one embodiment, the surgeon may also remove the surgical flap entirely, if not required for the surgical application at issue.
