Abstract
Abstract A hair grasping device includes a pair of hair engaging surfaces spring biased to a closed or engaged position in which a hair is grasped therebetween. The device further includes a first clamping member which is pivotally disposed with respect to a housing. The first clamping member includes the first hair engaging surface. A spring disposed within the housing biases the first hair engaging surface toward the second hair engaging surface of a second clamping member. A thumb wheel is employed to pivot the first clamping member against the bias of the spring. The thumb wheel is also used to actuate a switch which connects a high frequency energy source to one of the hair engaging surfaces to destroy the papilla area of a grasped hair.

Claim 7
Dependent Claim
22 words
The hair grasping device as recited in claim 1 wherein said actuating means is a thumb wheel supported pivotally within said housing.
Claim 8
Dependent Claim
201 words
A hair grasping device for grasping and holding a hair while high frequency electrical energy is applied thereto, said device comprising: a housing including an aperture and an opening; a first clamping member pivotally disposed with respect to said housing, at least a portion of said first clamping member extending through said opening and including a first hair engaging surface outside of said housing; a second clamping member supported by at least a portion of the housing and including a second hair engaging surface, at least one of said hair engaging surfaces being comprised of an electrically conductive material; biasing means for biasing said first clamping member toward said second clamping member for grasping and holding a hair between said first and second hair engaging surfaces; thumb wheel means pivotally disposed with respect to said housing for pivoting said first clamping member against the bias of said biasing means and said first hair engaging surface away from said second hair engaging surface, at least a portion of said thumb wheel means protruding from said housing through said aperture; and switch means positioned to be actuated by said thumb wheel means for supplying an electrical energy signal to the electrically conductive material.
Claim 9
Dependent Claim
201 words
A hair grasping device for grasping and holding a hair while high frequency electrical energy is applied thereto, said device comprising: a housing including an aperture and an opening; a first clamping member pivotally disposed with respect to said housing, at least a portion of said first clamping member extending through said opening and including a first hair engaging surface outside of said housing; a second clamping member supported by at least a portion of the housing and including a second hair engaging surface, at least one of said hair engaging surfaces being comprised of an electrically conductive material; biasing means for biasing said first clamping member toward said second clamping member for grasping and holding a hair between said first and second hair engaging surfaces; thumb wheel means pivotally disposed with respect to said housing for pivoting said first clamping member against the bias of said biasing means and said first hair engaging surface away from said second hair engaging surface, at least a portion of said thumb wheel means protruding from said housing through said aperture; and switch means positioned to be actuated by said thumb wheel means for supplying an electrical energy signal to the electrically conductive material.
