Anterior capsulotomy device and procedure
A device for performing an anterior capsulotomy procedure and a method using the same is presented. The device includes a body having a rotatable cutting element rotatably disposed on the proximal end. The cutting element further includes multiple surgical blades. In certain embodiments, the device further includes an arcuate member, wherein two surgical blades are attached at opposing ends and extend outwardly from the arcuate member. In using the device to perform an anterior capsulotomy, the device is inserted into an incision made in an eye and the surgical blades are brought in contact with the anterior capsule wall. The anterior capsule wall is then transformed by rotating the rotatable cutting element, creating an aperture there through.
1. A device for performing an anterior capsulotomy procedure, the device comprising:
a body having a proximal end and a distal end;
a rotatable cutting element rotatably disposed on the proximal end of the body, wherein the cutting element comprises a plurality of surgical blades and an arcuate member, wherein the arcuate member has a first end, a second end, a first surface, and a second surface, wherein the first end of the arcuate member opposes the second end of the arcuate member, wherein the first surface opposes the second surface, wherein a first surgical blade is attached to the first end of the arcuate member and extends outwardly there from, wherein a second surgical blade is attached to the second end of the arcuate member and extends outwardly there from
a shaft having a first end and a second end;
a first pulley, wherein the proximal end of the body is formed to include an aperture extending there through, wherein the shaft is rotatably disposed through the aperture, wherein the first pulley is attached to the first end of the shaft, wherein the second end of the shaft is attached to the second surface of the arcuate member; and
an actuator, wherein the actuator is movable between a first position and a second position, wherein the actuator is operatively coupled to the rotatable cutting element such that when the actuator is moved from the first position to the second position the arcuate member is rotated about 180 degrees.
2. The device of claim 1 , further comprising a second pulley operatively coupled to the actuator, wherein a first end of a fixed length of material is anchored to the first pulley and a second end of the fixed length of material is anchored to the second pulley.
3. The device of claim 2 , further comprising a handle disposed between the distal end of the body and the actuator.
4. The device of claim 1 , further comprising a second pulley operatively coupled to the actuator, wherein an endless belt interconnects the first pulley and the second pulley.
5. The device of claim 1 , wherein the actuator is manually operated.
6. The device of claim 5 , wherein the actuator is a finger trigger.
7. The device of claim 5 , wherein the actuator is a rotatable knob.
8. The device of claim 1 , wherein the arcuate member can be rotated about 182 degrees.
9. The device of claim 1 , wherein the device is disposable after a single use.
