Definitions
- ABSTRACT A catheter unit for use in operative cholangiography comprising a transparent elongated conduit member having a rounded, open distal end for insertion into the biliary tree and an open proximal end, and a transparent adapter in leak-proof engagement with the conduit member adjacent its proximal end.
- the adapter includes a recess communicating with the proximal end whereby a source of fluid may be placed in the recess for the transmittal of fluid to the conduit member.
- the conduit member includes a smoothly rounded enlargement set back from the distal end a distance of between about 3/16 inch and about one inch whereby, when the enlargement is located in the cystic duct of a patient, the distal end will be located in the common duct.
- FIG I v CATHETER UNIT FOR CHOLANGIOGRAPHY BACKGROUND OF THE INVENTION This invention relates to a medical device for use in operative cholangiography.
- Operative cholangiography is the x-ray visualization of the biliary system of a patient during an operation (typically, removal of the gallbladder).
- an operation typically, removal of the gallbladder.
- the surgeon typically attempts to determine the presence of stones in the duct system exclusive of the gallbladder itself. Stones in the common bile duct (i.e., the duct formed by the confluence of the cystic duct and the hepatic duc't), 'however, are typically difficult to detect by mere palpation.
- a catheter unit for use, in operative cholangiography which comprises a transparent elongated conduit member having a founded open distal end for insertion into a body cavity and an open proximal end.
- the unit also comprises a transparent adapter in leak-proof engagement with the conduit member'adjacent that members proximal end.
- the adapter includes a recess communicating with the conduit member proximal end, whereby a source of fluid may be placed in that recess for the transmittal of fluid to the conduit member.
- the conduit member includes a smoothly rounded enlargement set back from its :distal end a distance of between-about 3/16 inch and about 1 inch, whereby, when the enlargement is located in the cystic duct of a patient, the distal end will be located in the common duct of the patient.
- the enlargement comprises an integral head around the exterior of the conduit member; the enlargement is located approximately inch from the distal end; the conduit member includes a substantially rigidtip portion extending from thedistal end to at least a location of the enlargement and the remainder of the conduit member is flexible; and the adapter is bonded to the exterior surface of the conduit member thereby avoiding a reduction in the diameter of the conduit through which the fluid passes.
- FIG. l is a partly broken away perspective view of a catheter unit for use in operative cholangiography constructed according to the present invention
- FIG. 2 is an enlarged sectional view of a portion of the catheter unit of FIG. 1 adjacent the distal end thereof;
- FIG. 3 is a partly broken away side elevation of the distal portion of an alternative embodiment.
- the catheter unit 10 comprises a transparent conduit member 12 and a transparent adapter 14.
- the adapter 14 is bonded to the proximal end 16 of the conduit member around the exterior thereof.
- a recess 18 within the adapter 14 communicates with the distal end 16 of the conduit member and is sized and shaped to receive a standard syringe luer.
- the conduit member 12 is generally flexible but may include a portion 20 of less flexibility adjacent the distal end 22. (Alternatively a separate rigid molded tip member 23 (FIG. 3) may be secured to the flexible conduit member.)
- a smoothly rounded enlargement 24 is provided on the member 12.
- the enlargement is pref erably in the form of a molded or bonded bead of substantially the diameter ofa cystic duct and formed from the same plastic material (of any conventional type) which forms the body of the conduit member 12.
- the enlargement 24 is set back from the distal end 22 a distance of between about 3/16 inch and about 1 inch, preferably about inch.
- the conduit member 12 has a smoothly rounded profile, as at 26, immediately adjacent the distal end 22.
- an incision is made in the cystic duct and the distal end of the conduit member is inserted through the incision and the conduit member pushed into the duct until the enlargement 24 can be felt to be lodged in the cystic duct adjacent its intersection with the common duct.
- the distal end will be positively positioned within the common duct for ultimate distribution of dye to the common duct.
- a ligature is then tied around the cystic duct behind the enlargement which serves the additional purpose of cooperating with the ligature to retain the conduit member in place.
- this feature facilitates the working of the catheter past the spiral valves present in the cystic duct and the prevention of conduit collapse due to the ligature. Also the presence of the bead prevents the retrograde of the dye.
- conduit member 12 and the adapter 14 are conventionally filled with saline solution prior to insertion into the biliary system, the transparency of those elements provides for a convenient and positive determination of the presence or absence of air bubbles within the solution. Such air bubbles, if injected into the common duct, can be interpreted to be stones in the ultimate cholangiogram and are thus most undesirable.
- the ligature has been tied the luer of a syringe containing the dye is inserted into the recess of the adapter and the dye is forced into and through the conduit member 12. The dye thus enters the common duct of the patient and an x-ray may then be taken. Withdrawal of the conduit member from the duct system and removal of the gallbladder can proceed in a conventional fashion.
- a catheter unit for use in operative cholangiography comprising a transparent elongated conduit member having a rounded, open distal end for insertion into a body cavity and an open proximal end, and a transparent adapter in leak-proof engagement with said conduit member adjacent said proximal end, said adapter including a recess communicating with said proximal end whereby a source of fluid may be placed in said recess for the transmittal of fluid to said conduit member, said conduit member including a smoothly rounded enlargement thereof set back from said distal end, a distance of between about 3/16 inch and about one inch, whereby when said enlargement is located in the cystic duct of a patient said distal end will be located in the common duct of the patient.
- a catheter unit as claimed in claim 1 wherein said enlargement comprises an integral bead around the exterior of said conduit member.
- conduit member includes a substantially rigid tip portion extending from said'distal end to at least the location of said enlargement.
