Abstract
Instruments for placing complex sutures into animal tissues, including instruments useful in arthroscopic surgical techniques which minimize incision size. Manipulate the flat tissue by, for example, rolling, wrinkling, folding, bending or tucking the tissue so that a needle can be placed through the tissue more than once. Sutures are placed, for example from top-to-bottom and bottom-to-top with a single pass of a straight needle. Roll, wrinkle, fold, bend or tuck the flat tissue so that a needle can be placed through the tissue more than once. Suturing a loop through the tissue that another suture will pass through result in sewing both sides of the tissue. This will allow surgeons to place complex locking and grasping suture configurations that will significantly improve the repair.
Claims14
A surgical instrument for placing complex sutures into animal tissues, that instrument comprising:
- a first tip and a second tip operable to:
- grip a tissue above and below the tissue;
- and
- roll the tissue 180 degrees;
- a needle of the first tip operable to:
- pierce a fold of the tissue created by the roll and passing the needle and a suture through the rolled tissue from top to bottom and also from bottom to top.
A surgical instrument for placing complex sutures into animal tissues using one or more complex locking and grasping suture configurations to perform rotator cuff repair by suturing a loop through a biological tissue and passing a second suture through said loop.
A surgical instrument for placing complex sutures into animal tissues having three tips,
- the first tip positioned under a tissue,
- the second tip positioned on top of the tissue and to the left of the first tip, and
- the third tip positioned on top of the tissue and to the right of the first tip.
