    TECHNICAL FIELD
  • [0001]
    This invention pertains to apparatus for supporting in-use components of an Endoscopic Retrograde Cholangio-Pancreatography (ERCP) system. More particularly, the present invention relates to a belt having retainers for releasably attaching instrument components of an ERCP system, such as guide wires, tubes and catheters.
  • BACKGROUND OF THE INVENTION
  • [0002]
    Endoscopic Retrograde Cholangio-Pancreatography (ERCP) utilizes an endoscope with a catheter and a guide wire. A guide wire is place into position through a catheter that has been delivered via an open channel of the endoscope to a desired location within a patient. Afterwards, the guide wire can be used to further deliver instruments that are delivered about the guide wire to the desired location within the patient.
  • [0003]
    During surgical procedures to place and remove a guide wire, an endoscopic assistant is required to stow and retrieve the guide wire in a manner that is not going to contaminate the guide wire as it will later be inserted into the patient. In some cases, technicians attempt to coil the guide wires during removal and storage. However, the guide wires are made from a springy material that tends to straighten out into a linear configuration, thereby tending to uncoil if they are not held in a coil configuration. Furthermore, during a typical surgical procedure, the endoscopic assistant has their hands full which further complicates any attempt to coil and stow the guide wire as it is partially or completely removed from the endoscope and patient.
  • [0004]
    FIGS. 1-8 illustrate one presently understood prior art technique for delivering and interchanging guide wires and components for an Endoscopic Retrograde Cholangio-Pancreatography (ERCP) system. More particularly, FIG. 1 illustrates an endoscopic assistant 20 preparing to deliver saline solution from a syringe 16 through a side channel, or port 28 within a hand actuated cutting instrument 18 having a catheter 32. It is understood that catheter 32 is inserted into a port of an endoscope that has already been introduced through the mouth of the patient having lumenetic stints into the patient to a location proximate a treatment site. Catheter 32 is delivered through the lumen to the treatment site so that the saline solution is delivered to the treatment site. A cutting actuator on instrument 14 is gripped with a hand 24 of assistant 20 to hold port 28 in a desirable position while syringe 16 is inserted therein. At the same time, a coil 12 of guide wire 10 is held by the same hand 22 that holds syringe 16 in preparation for a next step that must be performed by the endoscopic assistant. The use of hand 22 to actuate syringe 16 while concurrently holding coil 12 can prove to be awkward at best.
  • [0005]
    FIG. 2 illustrates an endoscopist 34 supporting an endoscope 30 via a left hand 38 that is inserted into a patient's mouth. A right hand 36 is holding catheter 32 which is inserted into a channel, or open port 31 of endoscope 30. Endoscopist 34 is waiting for the endoscopic assistant to uncoil the guide wire (as shown in FIG. 3). FIG. 3 illustrates the endoscopic assistant 20 attempting to insert guide wire 10 into port 26 of catheter 32 while holding instrument 14 with hand 24 and, at the same time, holding coil 12 with hand 22. It becomes difficult for endoscopic assistant 20 to uncoil coil 12 without unraveling the coil while they are attempting to feed guide wire 10 to the endoscopist. FIG. 4 illustrates the endoscopist 34 waiting for catheter 32 and guide wire 10 to be fed forward while the assistant is having a difficult time uncoiling the guide wire 10 without having the guide wire uncoil (as depicted in FIG. 3).
  • [0006]
    FIG. 5 illustrates the endoscopic assistant 20 while they attempt to remove guide wire 10 from catheter 32 on instrument 14 via port 26. Left hand 24 is busy holding instrument 14, while right hand 22 is used to attempt a single-handed coiling of coil 12 which proves to be difficult, if not impossible. If this coiling is not performed successfully, the guide wire will touch the floor and cause contamination of the floor with bodily fluids. FIG. 6 illustrates the endoscopist 34 waiting for the endoscopic assistant of FIG. 5 while they attempt to coil guide wire 10 during removal of guide wire 10 from catheter 32.
  • [0007]
    FIG. 7 illustrates a typical storage cart that is provided on an endoscopy suite floor for use by an endoscopic assistant when storing a guide wire 10. More particularly, guide wire 10 has been attempted to be presented in the shape of a coil 12. However, coil 12 tends to unwind as guide wire 10 tends to maintain a linear shape due to the elastic memory in guide wire 10. Additionally, syringes 16 can be stored atop cart 40.
  • [0008]
    FIG. 8 illustrates an alternative means of storing coil 12 of guide wire 10 within a tray 42 atop cart 40. However, coil 12 tends to unravel and guide wire 10 can be left to overhang the top of cart 14 or touch the floor, which will contaminate the guide wire that may need to go back into the patient. In the case of both FIG. 7 and FIG. 8, bodily fluids can drip from guide wire 10 over the edge of cart 40 onto the endoscopy suite floor which is undesirable.
  • [0009]
    Accordingly, improvements are needed to help endoscopic assistants deliver, retrieve and stow guide wires for Endoscopic Retrograde Cholangio-Pancreatography (ERCP) systems.
  • SUMMARY OF THE INVENTION

  • [0040]
    FIG. 9 illustrates an article 50 of clothing for retaining components of an Endoscopic Retrograde Cholangio-Pancreatography (ERCP) system. Article 50 includes a flexible belt 52, a buckle 54, a plurality of retainers 60, 62, and 64, and a syringe holster 66. According to one construction, buckle 54 comprises a pair of mating male and female connectors 56 and 58, respectively. Also according to one construction, belt 52 comprises a body-encircling belt of flexible material, such as synthetic or Nylon webbing. Alternatively, leather, plastic, rubber strips or webs, or any other suitable material can be used. Retainers 60, 62 and 64 each provide an ERCP component retainer affixed to belt 52. Syringe holster 66 provides another retainer for releasably holding ERCP components.
  • [0041]
    As shown in FIG. 9, guide wire 10 is stored in the form of a coil 12 by retainer 60. A cutting instrument 14 is also stored by coiling a catheter portion 32 which is releasively held by retainer 62. Similarly, another catheter, or guide tube 32 is stored as a coil by retainer 64. Four different syringes 16 are stored within elastic slots in syringe holster 66 on belt 52.
  • [0042]
    FIG. 10 illustrates in enlarged detail coil 12 of guide wire 10 being supported by retainer 60 on apparatus 50. More particularly, FIG. 11 illustrates in further enlarged detail the use and construction of retainer 60. More particularly, retainer 60 comprises a pair of material strips 70 and 72 that have on opposed inner surfaces a strip of hook fasteners 74 and a strip of loop fasteners 76, respectively. When pressed together, the hook fastener 74 releasably attached with the loop fastener 76 to retain together material strips 70 and 72, while securing coil 12 of guide wire 10 therebetween. Material strips 70 and 72 are connected together along a top end 84 by a hinge 82 that is formed when a stitched region 78 is joined together by sewing strips 70 and 72 directly onto belt 52 using an array of stitches 80. Accordingly, a hinge 82 is formed between strips 70 and 72, whereas a lower free end 86 of strips 70 and 72 can be separated apart about hinge 82.
  • [0043]
    Accordingly, ERCP component retainers 60, 62 and 64 are each affixed to belt 52 at distinct locations. Each retainer 60, 62 and 64 includes a pair of material strips 70 and 72 connected together at one end with opposed inner surfaces.
  • [0044]
    FIG. 12 further illustrates the manner in which strips 70 and 72 can be releasably separated by pulling apart hook fastener 74 from loop fastener 76 about hinge 82. Accordingly, a top end 84 of strip 70 and 72 is secured together on belt 52, whereas a bottom end 86 of strip 70 and 72 are releasably separated by pulling apart hook 74 from loop 76. Such an operation can be done single-handedly by a user wearing belt 52 so as to store and retrieve loop 12 of guide wire 10 therebetween. Hence, retainer 60 on apparatus 50 provides an effective means for an endoscopic assistant to store and retrieve coil 12 of guide wire 10 from belt 52.
  • [0045]
    According to one construction, material strips 70 and 72 are elongate with a large dimension extending transverse to a large dimension of belt 52. Also according to the one construction, a top end of strips 70 and 72 are connected together via stitches which are further connected to belt 52. Furthermore, strip 72 is connected to belt 52 from a top end to a bottom end with stitches. Alternatively, strip 72 can be affixed to belt 52 with adhesive, rivets, or any other form of suitable fasteners. A free end of strip 70 is releasably attached to belt 52 via coaction of hook fasteners 74 with loop fasteners 76. According to one construction, hook fasteners 74 and loop fasteners 76 are formed from Velcro® fastener strips, available from Velcro USA Inc., 406 Brown Ave Manchester, N.H. 03103.
  • [0046]
    As shown in FIG. 13, an endoscopic assistant is wearing apparatus 10 in a secured manner with the buckle 54 (see FIG. 10) provided in a back, lumbar region (not shown) of assistant 20. Accordingly, retainer 60, 62, 64 and holster 66 are situated on an anterior portion of assistant 20. Guide wire 10 is stowed as a coil 12 by retainer 60 where wire 10 can be easily secured and released using a single hand of assistant 20. Article 50 also supports tool 14 which includes a catheter 32 by way of retainer 62. Likewise, another catheter 33 is supported by retainer 64. Retainer 62 and 64 can easily be manipulated using a single hand of assistant 20.
  • [0047]
    As shown in FIG. 14, details of apparatus 50 can be more clearly seen. More particularly, syringe holster 60 is formed by sewing together an elastic strip of web material 67 at discrete spaced apart locations so as to provide stretchable retention loops 69 each configured to receive a respective syringe 16 therein. Also depicted in FIG. 14, retainer 60, holster 66, retainer 62, and retainer 64 are substantially equal distance spaced apart along a frontal portion of apparatus 20 for relatively easy stowage and retrieval of coil 12 of guide wire 10, catheter 32, catheter 33 and syringes 16 by endoscopic assistant 20. With this configuration for retainers 60, 62 and 64, one retainer is affixed to a right lateral anterior portion of the belt and another pair of retainers is affixed to a left lateral anterior portion of the belt. This enables a user to affix a coiled guide wire on either side, which might depend on whether the user is dominantly right handed or left handed.
  • [0048]
    FIG. 15 illustrates the endoscopic assistant 20 wearing apparatus 50 after assistant 20 has retrieved a syringe using right hand 22 while holding instrument 14 with left hand 24 to facilitate placement of syringe 16 into side channel, or port 28. Coil 12 is shown stowed in retainer 60 for later retrieval by assistant 20 in a subsequent operation. Syringe 16 has been retrieved from holster 60 in a single-handed operation using right hand 22. Instrument 14 and accompanying catheter 32 were previously retrieved from container 62 by assistant 20.
  • [0049]
    FIG. 16 illustrates an endoscopist introducing catheter 32, presumably along with a guide wire contained therein at a pace that corresponds with the endoscopic assistant's ability to unwind and feed the guide wire and catheter to the endoscopist for placement within open port 31 of endoscope 60. Endoscopist 34 utilizes a left hand 38 to support endoscope 60 at a distal end within a patient while using right hand 36 to feed catheter 32 (and the guide wire) into port 31 and endoscope 30.
  • [0050]
    FIG. 17 illustrates endoscopic assistant 20 feeding guide wire 10 into side channel, or port 26 on instrument 14 which goes into catheter 32 and further to an endoscopist who places it into an endoscope (see FIG. 16). Assistant's left hand 24 is used to hold instrument 14 while right hand 22 is used to feed guide wire 10 from coil 12 while coil 12 is further secured within retainer 60.
  • [0051]
    FIG. 18 illustrates endoscopist 34 feeding catheter 32 and guide wire 10 into open port 31 of endoscope 30 as the endoscopic assistant feeds the guide wire 10 into catheter 32.
  • [0052]
    FIG. 19 illustrates endoscopist 34 retrieving catheter 32 and guide wire 10 from open port 31 of endoscope 30 using right hand 36 to pull catheter 32 and guide wire 10 from open port 31 while supporting endoscope 30 using left hand 38.
  • [0053]
    FIG. 20 illustrates endoscopic assistant 20 retrieving guide wire 10 to further coil guide wire 10 into coil 12 of retainer 60 while supporting instrument 14 using left hand 24. Such action occurs concurrently with the actions of endoscopist 34 in FIG. 19. Accordingly, the ability of assistant 20 to retrieve guide wire 10 through side channel 26 from catheter 32 speeds up the operations of endoscopist 34 in FIG. 19. Hence, retainer 60 further enables endoscopic assistant to single-handedly retrieve and coil guide wire 10.
  • [0054]
    FIG. 21 further illustrates endoscopic assistant 20 grasping guide wire 24 with both hands after instrument 14 has been stowed in retainer 62 by coiling catheter 32 of instrument 14 and affixing it into retainer 62. Additionally, catheter 33 has also been stored in retainer 64. Endoscopic assistant 20 uses left hand 24 in combination with right hand 22 to form individual additional coils with guide wire 10 that are subsequently secured alongside coil 12 within retainer 60. Accordingly, apparatus 50 further assists endoscopic assistant 20 in retaining and stowing coil 12 of guide wire 10.
  • [0055]

    It is understood that fasteners 60, 62 and 64 can be constructed with alternative configurations. For example, each material strip can be provided by flexible magnetic strips that can be releasably mated and demated via magnetic attraction to stow and release a coiled ERCP component during a surgical operation. Optionally, any form of strips that can be mechanically, magnetically or electrically mated and demated along their respective surface lengths would provide a suitable fastener construction for releasably retaining coiled ERCP components.
