Devices for performing blepharoplasty and methods of using the same
A blepharoplasty device includes a handle member, an elongate, curved first jaw member coupled to the handle member and having a first tissue contacting surface, and an elongate, curved second jaw member coupled to the handle member and having a second tissue contacting surface. The first and second jaw members are moveable relative to one another between a closed position and an open position to capture eyelid tissue and facilitate the cutting and subsequent reattachment of the eyelid tissue.
1. A blepharoplasty device comprising:
a handle member;
an elongate, curved first jaw member coupled to the handle member and having a first tissue contacting surface;
an elongate, curved second jaw member coupled to the handle member and having a second tissue contacting surface, the first and second jaw members being moveable relative to one another between a closed position and an open position, the first and second tissue contacting surfaces being spaced apart a distance D 1 in the open position and the first and second tissue contacting surfaces being spaced apart a distance D 2 in the closed position;
a biasing member configured to bias the device towards the closed position; and an actuator provided on the handle member and configured to counter the biasing member and move the device into the open position; and
a cutting guide formed in one or both of the first and second jaw members and configured to receive a portion of a cutting tool to guide the tool across at least a portion of a length of the first and second jaw members,
wherein the distance D 2 is smaller than the distance D 1 , and the distance D 1 is sized to allow the insertion of eyelid tissue between the first and second tissue contacting surfaces and the distance D 2 is sized to capture and secure the eyelid tissue inserted between the first and second tissue contacting surfaces.
2. The device of claim 1 , wherein the first jaw member is fixedly coupled to the handle member and the second jaw member is movable relative to the handle member to allow relative movement of the first and second jaw members.
3. The device of claim 2 , wherein the actuator comprises an arm member that is fixedly coupled to the second jaw member and movement of the arm member relative to the handle causes the device to move between the closed and open positions.
4. The device of claim 3 , wherein the biasing member comprises a spring member that is coupled to the arm member, the spring member exerting a force on the arm member to bias the second jaw member towards the first jaw member.
5. The device of claim 3 , wherein the first and second jaw members extend from the handle member in a generally cantilevered manner, and the handle member has a main body that extends generally perpendicularly to the first and second jaw members.
6. The device of claim 5 , wherein the arm member extends perpendicularly from the main body of the housing member.
7. The device of claim 1 , further comprising a pressure adjustment member that is moveable between a first position and a second position to adjust the distance D 2 , thereby varying a pressure exerted on the first and second tissue contacting surfaces in the closed position.
8. The device of claim 7 , wherein the pressure adjustment member is moveable to decrease the distance D 2 and increase the pressure on eyelid tissue captured between the first and second tissue contacting surfaces.
9. The device of claim 8 , wherein the pressure adjustment member comprises a set screw.
10. The device of claim 1 , further comprising a cutting tool that is received in the cutting guide provided in the device, the cutting tool being moveable across the at least a portion of the length of the first and second jaw members of the device to cut a portion of the eyelid tissue in a predetermined path defined by the cutting guide.
11. The device of claim 10 , wherein the cutting tool comprises an electrode cutting blade that is configured to operate at a first cutting frequency and a second cauterizing frequency.
12. The device of claim 1 , further comprising a cutting tool that is received in the cutting guide, the cutting tool being vertically movable between the first and second jaw members to cut a portion of the eyelid tissue in a predetermined path defined by the cutting guide.
13. The device of claim 1 , further comprising a plurality of suture guides formed in the first and second jaw members.
14. The device of claim 13 , further comprising a continuous suturing mechanism, the continuous suturing mechanism comprising a rotatable member configured to direct a suture needle through the plurality of suture guides.
15. The device of claim 1 , further comprising a stapling device coupled to the first and second jaw members, the stapling device configured to deliver staples to attach portions of the eyelid tissue in the closed position.
16. The device of claim 1 , further comprising a plurality of retraction members coupled to the first and second jaw members, the retraction members being configured to grip portions of the eyelid tissue while the device is in the closed position, wherein movement of the device to the open position causes adjacent edges of the eyelid tissue to separate.
17. The device of claim 1 , wherein the first and second tissue contacting surfaces comprise cushion members that extend from inner surfaces of the first and second jaw members.
