主权项

1. A surgical device for assisting in repairing or rehabilitation of damaged or severed tendons, the surgical device comprising:
a substantially half-conical shaped body portion having a first end, a second end, a length between said first and second ends, a width perpendicular to the length, an inner surface, and an outer surface opposite said inner surface, one of said first and second ends having a flared mouth defining substantially half a base of a cone, the other of said first and second ends being at least in part apical, said outer surface and said flared mouth each being at least in part arcuate in a plane parallel to the width, a portion of said substantially half-conical shaped body portion being adapted to be received within a pulley of a flexor tendon sheath, said outer surface being adapted to contact an inner portion of the pulley, said flared mouth being adapted to contact an edge of the pulley to define an entrance to a passage through the pulley, wherein, when a tendon end is passed through said substantially half-conical shaped body portion and the pulley, said flared mouth is adapted to prevent the edge of the pulley from having excessive contact with the tendon end, and said substantially half-conical shaped body portion is adapted to compress the tendon end.
