Abstract
Abstract A retractor of human or animal tissue comprises two arms with a spoon at one end, the other end being connected to a housing. The housing contains a spring which produces a force which spreads the two arms apart. The foot is connected to the housing by means of the spindle and a ball-joint. The lower face of the foot has a double-face adhesive.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
A retractor device for human or animal tissues, and more particularly for retracting upper and lower eyelids to expose the underlying eyeball for surgery, comprising: a pair of retracting arms each having corresponding first and second ends; a pair of corresponding spoons, each having a first curvature adapted to the shape of an eyeball and a second curvature adapted to the shape of an eyelid, articulatingly mounted to the first ends of said retracting arms; casing means disposed at the second ends of said retracting arms joining said second ends in a cooperating relationship and biasing the first ends of said retracting arms into retracted positions; and a strip attached to each one of said corresponding spoons, each strip having means to removably affix the strip to human or animal tissue in a position that biases said spoons away from the eyeball as said first ends of said retracting arms are being biased into retracted positions.
Claim 2
Dependent Claim
156 words
A retractor device for human or animal tissues, and more particularly for retracting upper and lower eyelids to expose the underlying eyeball for surgery, comprising: a pair of retracting arms each having corresponding first and second ends; a pair of corresponding spoons, each having a first curvature adapted to the shape of an eyeball and a second curvature adapted to the shape of an eyelid, articulatingly mounted to the first ends of said retracting arms; casing means disposed at the second ends of said retracting arms joining said second ends in a cooperating relationship and biasing the first ends of said retracting arms into retracted positions; and a strip attached to each one of said corresponding spoons, each strip having means to removably affix the strip to human or animal tissue in a position that biases said spoons away from the eyeball as said first ends of said retracting arms are being biased into retracted positions.
Claim 3
Dependent Claim
162 words
A retractor device for retracting the upper and lower eyelids of a human or an animal to expose the underlying eyeball for surgery, comprising: a pair of retracting arms each having corresponding first and second ends; a pair of corresponding spoons, each having a first curvature adapted to the shape of an eyeball and a second curvature adapted to the shape of an eyelid, pivotally mounted to the first ends of said retracting arms to move in substantially planar relationship therewith; casing means disposed at the corresponding second ends of said retracting arms, joining said corresponding second ends in a cooperating relationship and biasing the first ends of said retracting arms into retracted positions; and a strip attached to each of said corresponding spoons, each strip having means to removably affix the strip to human or animal tissue in a position that biases said spoons away from the eyeball as said first ends of said retracting arms are biased into retracted positions.
Claim 4
Dependent Claim
162 words
A retractor device for retracting the upper and lower eyelids of a human or an animal to expose the underlying eyeball for surgery, comprising: a pair of retracting arms each having corresponding first and second ends; a pair of corresponding spoons, each having a first curvature adapted to the shape of an eyeball and a second curvature adapted to the shape of an eyelid, pivotally mounted to the first ends of said retracting arms to move in substantially planar relationship therewith; casing means disposed at the corresponding second ends of said retracting arms, joining said corresponding second ends in a cooperating relationship and biasing the first ends of said retracting arms into retracted positions; and a strip attached to each of said corresponding spoons, each strip having means to removably affix the strip to human or animal tissue in a position that biases said spoons away from the eyeball as said first ends of said retracting arms are biased into retracted positions.
Claim 5
Dependent Claim
26 words
The retractor device of claim 2 wherein said casing means includes a spring arranged to bias the first ends of said retracting arms into retracted positions.
Claim 6
Dependent Claim
