An apparatus for inserting a staple into torn tissue such as the meniscus of the knee. The apparatus includes a pair of shafts individually movable in a longitudinal direction which are actuable from a handle mechanism. The shafts are movable sequentially so that the shafts disjunctively advance the prongs of the staple which is releasably held adjacent distal end portions of the shafts. A further embodiment of the device consists of a pair of needles detachably secured to a pair of anchoring members having a plurality of barb-like projections extending outwardly therefrom. The anchoring members are joined by a suture which connects adjacent the trailing ends of the anchoring members opposite the penetration end of the needles. The needles are engaged with the anchoring members to transmit a first pushing force applied to the needles to advance the anchoring members into the tissue, and are releasable from their engagement with the anchoring members responsive to a second pulling force applied to the needles in a direction opposite the pushing direction.
A surgical instrument for applying surgical fasteners to torn tissue, comprising: a handle mechanism; an elongated body portion extending from said handle mechanism, said body portion defining a longitudinal axis of said instrument; means positioned adjacent a distal end of said body portion remote
A surgical instrument for applying surgical fasteners to torn tissue, comprising: a handle mechanism; an elongated body portion extending from said handle mechanism, said body portion defining a longitudinal axis of said instrument; means positioned adjacent a distal end of said body portion remote from said handle mechanism for releasably engaging a fastener; advancing means including at least one shaft member associated with said handle mechanism and extending longitudinally within said body portion for linearly advancing said engaging means along said longitudinal axis to drive said fastener into said torn tissue; and a release member associated with said advancing means said release member being moveable into operative engagement with said advancing means to release said at least one shaft member to linearly retract said engaging means along said longitudinal axis to disengage said fastener from said engaging means, said fastener being positioned in said torn tissue.
