Abstract

Abstract A surgical towel and drape clamp having opposed jaw members connected to and opened and closed by the action of pivotally interconnected shank members having finger loop members and locking ratchet members is provided with tip means on one of said jaw members having a blunt distal end portion, the other of said jaw members being provided with tip means having a concave distal end portion which has a peripheral blunt edge. Upon placing a surgical towel or surgical drape between the tip means of said jaw members and manipulating the finger loops to close the jaw members and bring the locking ratchets into interengagement with each other, the surgical towel or surgical drape is trapped between the blunt distal end portion of one of the tip means and the concave distal end portion of the other tip means. The blunt distal end portion of one of the tip means and the peripheral blunt edge of the concave distal end portion of the other tip means preclude any puncturing, abrading and cutting of the surgical towel or surgical drape by the clamping action of the present invention.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 134 words
In a surgical towel and drape clamp having opposing jaw members connected to and opened and closed by the action of pivotally interconnected shank members having finger loop members and locking ratchet members and said jaw members further having tip means for holding and clamping surgical drapes, surgical towels and the like, the improvement in said tip means comprising the provision of: a blunt hemispheric distal end portion on one of said tip means; and a concave hemispheric distal end portion having a peripheral blunt edge on the other of said tip means, whereby, upon placing a surgical drape between said tip means and manipulating said finger loops to close said jaw members and locking ratchets, said drape is trapped between said blunt hemispheric distal end portion and said concave hemispheric distal end portion.
Claim 2
Dependent Claim 134 words
In a surgical towel and drape clamp having opposing jaw members connected to and opened and closed by the action of pivotally interconnected shank members having finger loop members and locking ratchet members and said jaw members further having tip means for holding and clamping surgical drapes, surgical towels and the like, the improvement in said tip means comprising the provision of: a blunt hemispheric distal end portion on one of said tip means; and a concave hemispheric distal end portion having a peripheral blunt edge on the other of said tip means, whereby, upon placing a surgical drape between said tip means and manipulating said finger loops to close said jaw members and locking ratchets, said drape is trapped between said blunt hemispheric distal end portion and said concave hemispheric distal end portion.
Claim 3
Dependent Claim 95 words
The improvement in tip means of claim 1, wherein: said blunt hemispheric distal end portion is provided with an externally radiused ball-like end portion; and said concave hemispheric distal end portion is provided with an internally radiused socket end portion having a relatively larger radius of curvature than that of said ball-like end portion whereby upon trapping a plurality of layers of said surgical drape between said distal end portions of said jaw tip means, a tight clamping is attained while puncturing or cutting of said surgical drape by said jaw tip means is prevented.
