Abstract
Abstract An arthroscopic clip and insertion tool for same for repairing tears in fibrocartilage and soft tissue. The instrument for applying these clips has a pair of opposed jaws, each with at least one notch for holding the barbs of the clip. The jaws are biased apart in a normally open position and are interconnected to an actuating handle. The instrument further includes a device which closes the jaws when the handles are moved a first way relative to one another and opens them when the handles are moved the other way.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
116 words
An arthroscopic instrument for applying barbed arthroscopic clips for repair of tears in fibrocartilage and soft tissue comprising: a pair of opposed jaws each having at least one notch for holding the barbs of said clip; biasing means for separating said jaws in a normally open position; an actuating handle having opposed handle members; means for interconnecting said handle and said jaws; means for closing said jaws when said handle members are moved a first way relative to one another and opening said jaws when said handle members are moved the other way relative to one another; and means for releasing said clip from said jaws; said releasing means being independent of said jaw closing means.
