Laparoscopic stone safety device and method
First Claim
1. A laparoscopic surgical netting assembly for conducting a laparoscopic gallbladder or bile duct procedure through a laparoscopic port having an external end extending axially above an external surface of the abdominal wall and an abdominal end extending from below an internal surface of the abdominal wall and into an abdominal cavity, the laparoscopic port including an internal through bore extending between the external end and the abdominal end to provide a conduit into the abdominal cavity, and a carrier sheath received within the laparoscopic port internal through bore and having an carrier sheath external end and an instrument guide abdominal end, the carrier sheath external end extending above the external surface of the abdominal wall and the carrier sheath abdominal end extending below the laparoscopic port abdominal end and proximal to the gallbladder or bile duct, the carrier sheath including at least one through channel for conveying and deploying the surgical netting assembly, the surgical netting assembly comprising:
- a collapsible and expandable frame, the frame when expanded defining a perimeter substantially greater than the frame when collapsed and passed through the at least one through channel in the carrier sheath;
a fluid permeable netting suspended on the frame for collecting stones released from the gallbladder or bile duct;
a frame control rod, the control rod being connected to the frame and extendable and retractable within the at least one through channel in the carrier sheath; and
a deployment rod for acting on a portion of the frame removed from a connection of the control rod to the frame, the deployment rod being movable within the at least one through channel in the carrier sheath which receives the control rod or another of the at least one through channel in the carrier sheath for altering a configuration of the frame when expanded.

Abstract
A laparoscopic netting assembly is provided for conducting a gallbladder or bile duct procedure through one of the throughbores in a carrier sheath, which in turn may be positioned within a laparoscopic port. The carrier sheath includes at least one through channel for conducting a frame control rod, and optionally a deployment rod. The netting assembly includes a collapsible and expandable frame and a fluid permeable netting, which is preferably comprises a plurality of netting layers, suspended on the frame for collecting stones released from the gallbladder or bile duct. The frame is sized to also collect the gallbladder. The carrier sheath may also include one or more through channels for a cutting instrument.
