Embodiment Construction

[0031]The device of the present invention provides a membrane that acts as a trapping mechanism for immobilizing, blocking or trapping stones and stone fragments as they exit the gallbladder and bile ducts, thereby preventing undesired passage into the abdominal cavity. migrate. The membrane, which can be a thin layer, or various three-dimensional geometric configurations, or a combination thereof, covers the subhepatic space in the peritoneal cavity and serves to prevent migration of stones after they have been expelled from the gallbladder or bile duct. The present invention prevents stone migration and thus reduces patient injury and common complications associated with stone retrieval from laparoscopic cholecystectomy and laparoscopic common bile duct exploration.

[0032] The mesh assembly may be compressed and pre-packed into a carrier tube sheath that is deployed by insertion through the carrier sheath within a laparoscopic port. The distal end of the device can be wit...

Abstract

A laparoscopic netting assembly is provided for conducting a gallbladder or bile duct procedure through one of the throughbores in a carrier sheath (40), which in turn may be positioned within a laparoscopic port (5). The carrier sheath includes at least one through channel for conducting a frame control rod (90), and optionally a deployment rod (95). The netting assembly includes a collapsible and expandable frame (20) and a fluid permeable netting (10), which preferably includes 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.

Description

technical field [0001] The present invention relates generally to a medical device and, more particularly, to a laparoscopic surgical instrument of the type used in gallbladder and bile duct exploration and stone removal procedures. This surgical safety device reliably prevents stone migration from the gallbladder or bile ducts from the hepatic and bile duct branches and the common bile duct. Background technique [0002] Many patients develop stones in their gallbladder. A diseased gallbladder can contain tens or hundreds of stones and is typically removed by open surgery or minimally invasive laparoscopic cholecystectomy. During laparoscopic cholecystectomy, the gallbladder is often cut and torn. As a result, stones may be scattered into the abdominal cavity in the abdomen. Such undesired events occur in approximately 10%-40% of performed procedures. Without the present invention, non-retrieved stones adjacent to the abdominal cavity, liver, or other vital organs could...
