Grasper-stitcher device for arthroscopic anterior cruciate ligament repair
First Claim
1. A grasper-stitcher device adapted to grasp tissue, and permit passage of sutures through the grasped tissue comprising, in combination:
- a longitudinal, elongated housing, having a proximate end connected to a handle means and a distal end comprising a jaw assembly means;
an inner hollow tubular member capable of axial motion within the elongated housing assembly, with a proximate end attached to said handle means, and a distal end connected to a proximate end of at least one movable first jaw member of said jaw assembly means at the distal end of the tubular housing;
said jaw assembly means further comprising said movable first jaw member laterally opposed from a fixed second jaw member, wherein each jaw member further comprises a pair of arcuate finger-like elements that are laterally spaced and parallel to a longitudinal axis of the housing, distal ends of each jaw member laterally are spaced apart when said first jaw member is in a relatively closed position, and an axially open passage is provided between an entrance at the proximate end of the elongated housing through the hollow inner tubular member and out through the arcuate jaw members at the distal end of the housing, even when said jaw members are in a relatively closed position, whereby a long surgical needle may be inserted into the proximate end of the housing, pass through the hollow inner tubular member and exit through the jaw assembly means and suture a tissue grasped within said jaw assembly.

Abstract
An elongated grasper-stitcher instrument particularly useful for arthroscopic knee surgery, permits the grasping and stitching of a stump of torn tissue, such as anterior cruciate ligament, or meniscus, during arthroscopic knee surgery. The grasper-stitcher permits multiple loops of suture to engage a stump of tissue at varying levels, and subsequent anchoring of the suture outside of a bore in the lateral pfemoral condyle. The arthroscopic tool defines a pair of atromatic grasping jaws, through parallel fingers of arcuate enclosure, which are spaced laterally so as to accommodate axial passage of a long surgical needle into the proximate end of the elongated tubular housing, through the hollow inner tube, and out through the jaw assembly, even for positions of relative closure between the movable jaw and the fixed jaw. The invention further comprises a method of comparing tissue by permitting several plurality of loops to be defined in the tissue by inserting a first needle with suture through the tissue, and using the opposite end of the suture with a second needle that also is inserted through the hollow tube and out through a receiving cannular, on the opposite side of the tissue through which the loop has been defined.
