Laparoscopic cholangiogram device |
| abstract |
A surgical instrument for facilitating the injection of a contrast fluid into the cystic duct during the course of a laparoscopic cholecystectomy procedure comprises an elongated, rigid outer tubular member whose outer diameter permits it to pass through the lumen of a trocar penetrating the patient's abdominal wall and of a length allowing the distal end of the instrument to abut the patient's cystic duct. Affixed to the proximal end of the outer tubular shaft is a grip that includes a plunger which can be reciprocally moved in the longitudinal direction and joined to the plunger is an inner tube which can be joined at its proximal end to a source of contrast fluid and which extends through the lumen of the outer tubular shaft. Affixed to the distal end of the inner tube is a hollow hook-shaped needle which is in fluid communication with the lumen of the inner tube and which has a sharpened distal end for piercing through the wall of the cystic duct when the plunger is depressed to thereby hook and hold the instrument with the open end of the needle in the cystic duct. By injecting contrast fluid into the proximal end of the instrument, it flows through the inner tubular member and the hollow needle into the cystic duct. |
