Abstract
A device comprising a trocar may include a trocar body having a channel formed therein; a first opening at a first end of the channel, and an end cap at a second end of the channel. The end cap may include an end cap body at least partially enclosing the channel at the second end of the channel, an opening formed in the end cap body at the second end of the channel allowing passage of a mechanical feature through the first opening and through the second opening, and a tongue extending substantially perpendicularly from a surface of the end cap internal to the channel such that the tongue and at least one wall of the channel defines a groove.
Claims18
A device comprising a trocar including:
- a trocar body having a channel formed therein;
- a first opening at a first end of the channel;
- and
- an end cap at a second end of the channel, the end cap comprising:
- an end cap body at least partially enclosing the channel at the second end of the channel;
- an opening formed in the end cap body at the second end of the channel allowing passage of a mechanical feature through the first opening and through the second opening;
- and
- a tongue extending substantially perpendicularly from a surface of the end cap internal to the channel such that the tongue and at least one wall of the channel defines a groove.
A method for forming a device comprising a trocar including:
- forming a channel in a trocar body, with a first opening at a first end of the channel;
- and
- forming an end cap at a second end of the channel, the end cap comprising:
- an end cap body at least partially enclosing the channel at the second end of the channel;
- an opening formed in the end cap body at the second end of the channel allowing passage of a mechanical feature through the first opening and through the second opening;
- and
- a tongue extending substantially perpendicularly from a surface of the end cap internal to the channel such that the tongue and at least one wall of the channel defines a groove.
A method comprising:
- inserting a probe into an interior of a channel of a trocar via a first opening of the trocar at a first end of the trocar;
- positioning a second end of the trocar proximate to a magnetic suture;
- further inserting the probe into the trocar such that a magnetic tip formed on an extension extending from the probe passes through a second opening of the trocar at the second end of the trocar to place the magnetic tip in sufficient proximity to the magnetic suture such that a magnetic force between the magnetic tip and magnetic suture attracts the magnetic tip suture to the magnetic tip;
- and
- retracting the probe within the trocar to pull the magnetic tip and at least a portion of the suture into the interior of the channel of the trocar.
A magnetic suture comprising:
- a plurality of strands;
- and
- ferromagnetic material applied to the plurality of strands such that the magnetic suture is attracted to a magnet.
