Abstract

A clamp is meant to be used by eye surgeons during surgery to correct a condition known to lay persons as cross-eyes. The clamp is comprised of a solid first plate, a second plate comprising a longitudinal slit adapted to receive a knife blade, and a locking means for locking the eye muscle in place between the two clamps. The method for using the clamp during surgery is also disclosed.

Claims

1. A strabismus recession clamp comprising:

a) a solid first plate comprising a top surface wherein the top surface is adapted to receive an eye muscle during a recession procedure;

b) a second plate comprising a longitudinal slit wherein the longitudinal slit comprises a plurality of hatch marks and is adapted to receive a knife blade during the recession procedure and the second plate is adapted to be received in the top surface of the first plate after the eye muscle is received in the top surface of the first plate and thereby a first groove for initial suturing of the eye muscle is formed between the first plate and the eye muscle and a second groove for recession of the eye muscle is formed between the first plate and the eye muscle; and

c) a locking device for securing the second plate into position over the eye muscle after the second plate is received in the top surface of the first plate.

3. A method for performing muscle recession surgery using the strabismus recession clamp of claim 1 comprising the steps of:

a) locating the first solid plate of the strabismus recession clamp on top of the sclera on top of the sclera and the muscle at the muscle insertion;

b) placing an eye muscle on the top surface of the first solid plate of the strabismus recession clamp;

c) placing the second plate of the strabismus recession clamp onto the top of eye muscle;

d) securing the second plate into position by means of the locking device;

e) threading a double armed suture through the first groove of the second plate and then placing a central knot and two first locking bites in the double armed suture;

f) determining a point of recession for the eye muscle at one of the plurality of hatch marks on the longitudinal slit and then placing a fixation device at the point of recession in the longitudinal slit;

g) passing the double armed suture around the fixation device and back to an edge of the eye muscle wherein a second locking bite in placed in the double armed suture;

h) removing the fixation device;

i) repeating steps f and g on an opposite edge of the eye muscle;

j) tieing the ends of the double armed suture together to form a complete loop;

k) incising the eye muscle by use of a knife through the longitudinal slit in the second plate;

l) releasing the locking device and removing the second plate;

m) and adjusting the position of the eye muscle as necessary.

2. A strabismus recession clamp for reoperations comprising:

a) a solid first plate comprising a top surface wherein the top surface is adapted to receive an eye muscle during a recession procedure;

b) a second plate comprising a longitudinal slit wherein the longitudinal slit comprises a plurality of hatch marks and is adapted to receive a knife blade during the recession procedure and the second plate is adapted to be received in the top surface of the first plate after the eye muscle is received in the top surface of the first plate and thereby a first groove for initial suturing of the eye muscle is formed between the first plate and the eye muscle; and

c) a locking device for securing the second plate into position over the eye muscle after the second plate is received in the top surface of the first plate.
