Claim 1
Independent Claim
298 words
A surgical thread dispenser comprising: a. a flat, cylindrical reel comprising a hub having an axial opening therein and flanges on each side of said hub which in cooperation with each other and said hub form an annular groove adapted to carry a length of surgical thread wound thereon in a plurality of turns; b. a reel case comprising a circular backing plate at one side of the reel having a centrally located spindle extending outward from said backing plate for supporting the hub of said reel, the outside diameter of said spindle being sized to receive the axial opening in said hub to allow the reel to rotate freely on said spindle, the backing plate having an annular peripheral rim extending radially beyond the outer periphery of said reel and axial beyond the outer flange of said reel, said rim having an opening therein for dispensing the surgical thread from the reel through the rim; c. a finger ring sized to accept the middle finger of an adult human hand, and oriented in the same plane as said backing plate; and d. a membrane extending between said finger ring and said backing plate and having a line of weakness extending transversely across the width of the membrane intermediate said finger ring and said backing plate, said finger ring being spaced from said backing plate a distance that when the finger ring is placed over a middle finger of a hand and the membrane is bent along said line of weakness to provide an angle between the plane of the finger ring and the plane of the backing plate, the dispenser is positioned in the palm of the hand and the suture is available for withdrawing from the reel through the opening in the rim of the case.
