LAPAROSCOPIC INSTRUMENT SYSTEM FOR STONE REMOVAL

摘要

A laparoscopic port adapter assembly 10 for conducting bile duct and related procedures, including a laparoscopic port 11, an introducer sheath 12 and a multiple conduit instrument guide 13. The instrument guide 13 may be inserted into a bile duct 14 to facilitate concurrent introduction of multiple instruments directly into the bile duct 14 without need for forceps manipulation of instruments through additional laparoscopic ports. The procedure may be conducted and viewed in real-time video to improve procedural efficiency and safety. Inventive related useful instruments and procedures are included to complement use and flexibility of the laparoscopic port adapter assembly 10. A preferred embodiment may include use of a three-conduit instrument guide 13 and concurrent introduction of a lithotripter 32, choledochoscope 31 and irrigative catheter 34 directly in the bile duct 14.
