An instrument for shaping a mouth part of a drilled tunnel provided in a bone. The instrument includes a shaft having a longitudinal axis and a first and a second end. The first end of the shaft is provided with a projection, which includes a blade for shaping the mouth part of the drilled tunnel when the instrument is turned around the longitudinal axis of the shaft. The instrument is asymmetric at an intersecting surface perpendicular to the longitudinal axis and intersecting with the blade, the instrument thus shaping the surfaces surrounding the first end only substantially within an area corresponding with a turning angle of such a turning movement.

Instrument

A surgical tissue fixation system is described, including: (1) a bioabsorbable tissue fixation plate having optionally a plurality of through-holes arranged in alternating relation along the plate; (2) bioabsorbable fasteners adapted for insertion into the through-holes to secure the plate to underlying bodily tissue or bone; and (3) an installation instrument which triggers (strikes or shoots) fasteners one after one, in rapid succession, into the through-holes made through the plate and into the underlying bodily tissue or bone, which also optionally includes drillholes.

Surgical system for tissue fixation

The device of the present invention is designed for repairing a tear in soft and/or tough tissue of a patient, such as a tear in the meniscus of the knee. The device has a conduit, such as a cannula, that may be easily inserted into the patient and through which the fastener is delivered to the patient. This conduit is aligned with a seat for holding a fastener and the fastener is pushed, e.g., by a piston, from its seat and through the conduit and into the patient. In a preferred embodiment of the invention, the shape of the conduit exactly matches the shape of the cross-section of the fastener so that the surgeon may more accurately direct the angle and location at which the fastener enters the patient.
