Abstract
A lid speculum that operates in an anatomically correct manner. The speculum has a first blade and a second blade that can pivot about an axis of rotation. The speculum is constructed so that the axis of rotation is essentially parallel with and posterior to a line that intersects a medial canthi and lateral canthi of an eye. With such an arrangement the blades will move in a radial manner that corresponds to the shape of the globe. This movement tends to lessen kinked pressure points in the eyelid.
Claims12
A lid speculum that can be used on an eye that has a medial canthi and a lateral canthi, comprising:
- a first blade that rotates about an axis of rotation that is essentially parallel with a line that intersects the medial canthi and the lateral canthi, said first blade having a proximal end attached to a pivot point and an unattached distal end;
- a second blade that pivots about the axis of rotation, said second blade having a proximal end attached to said pivot point and an unattached distal end;
- and,
- a manipulator that can be activated to pivot said first and second blades about said pivot point.
A lid speculum comprising:
- a first blade;
- a second blade;
- a first arm attached to said first blade;
- a second arm attached to said second blade;
- a pivot pin attached to said first and second arms such that said first and second blades pivot about said pivot pin;
- a manipulator;
- and,
- a plurality of universal joints that couple said first and second arms to said manipulator.
A method for retracting an eyelid of an eye that has a medial canthi and a lateral canthi, comprising;
- pivoting a first blade and a second blade about an axis of rotation that is essentially parallel with a line that intersects the medial canthi and the lateral canthi, and about a single pivot point by actuating a manipulator wherein the first and second blades each have unattached distal ends.
A lid speculum that can be used on an eye that has a medial canthi and a lateral canthi, comprising:
- a first blade that rotates about an axis of rotation that is essentially parallel with to a line that intersects the medial canthi and the lateral canthi;
- a second blade that pivots about the pivot axis;
- and,
- a manipulator that can pivot said first and second blades said manipulator includes a lead screw that is connected to a linkage mechanism which is coupled to said first and second blades.
