Abstract
Abstract A surgical device provides sterile compression of the capillary blood vessels about the periphery of an operating area. The device is a circular or elliptical ring with an outwardly extending arm adapted to receive an illumination source. The ring is rigid and preferably transparent. The under-surface of the ring compresses a narrow zone of skin about the operating area. The illumination source functions both to illuminate the operating area and as a handle for the device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
176 words
A surgical hemostatic light comprising: an annulus having a top wall, a side wall extending downwardly from said top wall, and a bottom wall, said annulus having an opening from and between said top and said bottom walls, said opening being of sufficient size to permit biopsy of a predetermined surgical area, said bottom wall having at least one edge completely surrounding said opening, said edge being adapted to restrict blood flow in the area surrounded by said opening; an integrally formed arm extending radially outwardly from said annulus having a first end and a second end, said first end being attached to said annulus and said second end having an axially opening socket formed in it; and a penlight removably mounted in said axially opening socket of said arm, said penlight and said arm defining a cantilever structure for applying force to the opening surrounding edge of said annulus, the annulus and arm being made of lightconducting material, and the light of the penlight being transmitted thereby to illuminate an area surrounded by said annulus.
Claim 2
Dependent Claim
176 words
A surgical hemostatic light comprising: an annulus having a top wall, a side wall extending downwardly from said top wall, and a bottom wall, said annulus having an opening from and between said top and said bottom walls, said opening being of sufficient size to permit biopsy of a predetermined surgical area, said bottom wall having at least one edge completely surrounding said opening, said edge being adapted to restrict blood flow in the area surrounded by said opening; an integrally formed arm extending radially outwardly from said annulus having a first end and a second end, said first end being attached to said annulus and said second end having an axially opening socket formed in it; and a penlight removably mounted in said axially opening socket of said arm, said penlight and said arm defining a cantilever structure for applying force to the opening surrounding edge of said annulus, the annulus and arm being made of lightconducting material, and the light of the penlight being transmitted thereby to illuminate an area surrounded by said annulus.
Claim 3
Dependent Claim
61 words
The surgical hemostatic light of claim 1 wherein said bottom wall is formed by the material thickness of said side wall, said side wall having an inboard face adjacent said opening and an outboard face, at least one of said inboard and said outboard faces being chamfered so that it converges with the other of said inboard and said outboard faces.
Claim 4
Dependent Claim
20 words
The surgical hemostatic light of claim 2 wherein said top wall and said side wall are L-shaped in cross section.
Claim 5
Dependent Claim
228 words
A surgical hemostatic light comprising: an annulus having a top wall, a side wall attached to said top wall and extending perpendicularly downwardly therefrom, and a bottom wall, said annulus having an opening from and between said top and said bottom walls, said bottom wall comprising the material thickness of said side wall, said side wall having an inboard face adjacent said opening and an outboard face, one of said inboard and outboard faces being chamfered to meet the other of said inboard and said outboard faces along an end of said side wall opposite attachment of said side wall and said top wall thereby defining a blood reStricting edge about said opening, said opening being of sufficient size to permit biopsy of a predetermined surgical area; an integrally formed arm extending radially outwardly from said annulus having a first end and a second end, said first end being attached to said annulus along said side wall and said second end having an axially opening socket formed in it; and a penlight removably mounted in said axially opening socket of said arm, said penlight and said arm defining a cantilever structure for applying force to said blood restricting edge of said annulus, the annulus and arm being made of light-conducting material, and the light of the penlight being transmitted thereby to illuminate an area surrounded by said annulus.
Claim 6
Dependent Claim
228 words
A surgical hemostatic light comprising: an annulus having a top wall, a side wall attached to said top wall and extending perpendicularly downwardly therefrom, and a bottom wall, said annulus having an opening from and between said top and said bottom walls, said bottom wall comprising the material thickness of said side wall, said side wall having an inboard face adjacent said opening and an outboard face, one of said inboard and outboard faces being chamfered to meet the other of said inboard and said outboard faces along an end of said side wall opposite attachment of said side wall and said top wall thereby defining a blood reStricting edge about said opening, said opening being of sufficient size to permit biopsy of a predetermined surgical area; an integrally formed arm extending radially outwardly from said annulus having a first end and a second end, said first end being attached to said annulus along said side wall and said second end having an axially opening socket formed in it; and a penlight removably mounted in said axially opening socket of said arm, said penlight and said arm defining a cantilever structure for applying force to said blood restricting edge of said annulus, the annulus and arm being made of light-conducting material, and the light of the penlight being transmitted thereby to illuminate an area surrounded by said annulus.
