Abstract
A laparoscopic surgical system configured for cooperation with a trocar is described. In one configuration, the system is configured to expand to accommodate trocars of varying dimensions. In another configuration, which is not necessarily exclusive of the first configuration, the system may function to provide an anchoring and closure system for use in laparoscopic surgery.
Core Innovation
The invention relates to a laparoscopic system configured for engagement with an aperture provided in an abdominal wall. The system comprises an expandable housing that defines a lumen for receipt and delivery of a trocar into an abdominal cavity, and an outer resting portion that rests against an outer surface of the abdominal wall. The outer resting portion extends circumferentially about the lumen to define a path and an entry port through which the trocar is presented into the lumen.
The expandable housing has an outer resting portion comprising a first part and a second part moveable relative to each other so that expansion varies a length of the path to accommodate trocars of different dimensions. The housing further defines a first needle guide channel and a second needle guide channel within an abdominal wall engaging portion. The needle guide channels are provided on opposite sides of the lumen, each with an entry port proximal the outer resting portion and an exit port above a distal end portion of the abdominal wall engaging portion.
The needle guide channels are dimensioned to receive a needle driver and allow delivery of suture or an anchor through the housing and directly into the abdominal wall. The needle guide channels are separate and distinct from the lumen such that, on delivery, suture does not pass through the lumen. Expansion varies the path length while maintaining the first needle guide channel and the second needle guide channel substantially opposite one another irrespective of the length of the path.
Claims Coverage
The partial content includes one independent claim. The claim set is directed to a laparoscopic system with two inventive features: an expandable housing that adapts path length to trocar dimensions, and two separate needle guide channels positioned opposite one another to deliver suture or anchors directly into the abdominal wall while keeping suture separate from the trocar-receiving lumen.
Expandable outer resting portion defining an entry port path
An expandable housing defines a lumen for receipt and delivery of a trocar into an abdominal cavity, with an outer resting portion configured to rest against an outer surface of the abdominal wall. The outer resting portion comprises first and second moveable parts and extends circumferentially about the lumen to define a path and an entry port through which the trocar is presented into the lumen.
Opposed first and second needle guide channels separate from the lumen
A first needle guide channel and a second needle guide channel are defined within an abdominal wall engaging portion, provided on opposite sides of the lumen, and each has an entry port proximal the outer resting portion and an exit port above a distal end portion of the abdominal wall engaging portion. The needle guide channels allow delivery of suture or an anchor through the housing and directly into the abdominal wall, and the needle guide channels and the lumen are separate and distinct such that suture does not pass through the lumen on delivery.
Path-length expansion while maintaining substantially opposite needle guide channels
Expansion of the housing by relative movement of the first part and the second part varies a length of the path to operably accommodate trocars of different dimensions while maintaining the first needle guide channel and the second needle guide channel substantially opposite to one another irrespective of the length of the path.
The core coverage is for an expandable laparoscopic trocar interface that varies path length for different trocar dimensions while maintaining opposed needle guide channels that deliver suture or an anchor directly into the abdominal wall without routing the suture through the lumen.
