  • Patent number: 4738255
    Abstract: A suture anchor system that includes a drill for turning into a bone mass with sissoring blades pivotally connected in a longitudinal drill shaft slot proximate to a cutting end thereof, the blade ends to sissor to extend cutting edges outwardly therefrom, which sissoring occurs at a certain depth of penetration into the bone mass, cutting a flared or skirted hole therein, to receive a suture anchor whereto a suture is secured. The suture anchor consists of a suture rivet and slotted ring and is formed by moving the suture rivet into the slotted ring, that ring breaking at spaced apart slots formed therein and flaring into a skirt, the anchor rivet and slotted ring thereby locked together as the suture anchor, which suture anchor has approximately the same shape but a slightly lessor diameter than the hole formed in the bone mass.
