Abstract

Claims (24)

1. A forceps apparatus, comprising:

a first handle and a second handle coupled to one another near or at respective proximal ends via a common pivoting connection such that in a first unbiased configuration the first and second handle are spaced apart and in a second biased configuration the first and second handle are urged towards one another about the pivoting connection when squeezed together, wherein the first and second handles each have a thickness which reduces proximally of the pivoting connection;

a first paddle coupled to the first handle and defining a first inner surface;

a second paddle coupled to the second handle and defining a second inner surface which is positioned in apposition to the first inner surface, wherein the first and second paddles define a plane when compressed against one another; and

a planar debriding member extending proximally from the first and second handles and having a planar thickness which reduces and curves gently to define a debriding edge around a periphery of the planar thickness and having a radius such that the debriding edge is sufficiently configured to scrape tissue along a margin of an eyelid in proximity to one or more meibomian glands,

wherein the debriding member defines a debriding plane which is coplanar or parallel with the plane defined by the first and second paddles when compressed, and

wherein the planar thickness is relatively thinner from the first and second handles for debriding the margin and the planar thickness is also relatively thinner than the pivoting connection.

2. The apparatus of claim 1 wherein the debriding member has a length between 10.00 mm to 11.00 mm.

3. The apparatus of claim 1 wherein the debriding member has a width between 8.00 mm to 9.00 mm.

4. The apparatus of claim 1 wherein the debriding member has a thickness of between 0.40 mm to 0.55 mm.

5. The apparatus of claim 1 wherein the debriding member reduces and curves gently into an elliptical shape.

6. The apparatus of claim 1 wherein the first and second paddles are separated by a resting open gap when uncompressed against one another.

7. The apparatus of claim 1 wherein the periphery of the planar thickness presents a smooth transition to the pivoting connection.

8. The apparatus of claim 1 wherein a length of the first and second paddles defines an angle of 35° relative to a longitudinal axis of the forceps.

9. The apparatus of claim 1 further comprising one or more strips configured to adhere to an underlying region of skin in proximity to one or both eyes of a subject such that the one or more strips allow for the subject to blink naturally with minimal, or no restriction from the one or more strips.

10. The apparatus of claim 9 wherein the one or more strips are configured to emit thermal energy to the underlying region of skin, and wherein the one or more strips are shaped to follow a location of one or more meibomian glands contained within the underlying region of skin.

11. The apparatus of claim 9 further comprising a controller in communication with the one or more strips, wherein the controller is programmable to monitor and induce a temperature in the one or more strips to provide a therapy.

12. A forceps apparatus, comprising:

a first handle and a second handle coupled to one another near or at respective proximal ends via a common pivoting connection, wherein the first and second handles each have a thickness which reduces proximally of the pivoting connection;

a first paddle coupled to the first handle and defining a first inner surface;

a second paddle coupled to the second handle and defining a second inner surface which is positioned in apposition to the first inner surface, wherein the first and second paddles define a plane when compressed against one another; and

a member extending proximally from the first and second handles and having a planar thickness which reduces and curves gently to present an atraumatic proximal edge around a periphery of the planar thickness and having a flattened thickness which is also relatively thinner than the pivoting connection,

wherein the member is coplanar or parallel with the plane defined by the first and second paddles when compressed and further defines a notch having a recessed, atraumatic debriding edge along a curved edge of the flattened thickness in proximity to the proximal edge and sized for receiving and maintaining a lid margin within the notch.

13. The apparatus of claim 12 wherein the notch further defines atraumatic side edges on either side of the recessed debriding edge.
