Multiple bladed surgical knife and method of use

A surgical knife comprising:

• a base;
• a plurality of parallel blades;
• means for securing the blades to the base;
• and
• means for shifting a longitudinal position of the blades with respect to each other and with respect to the base between a first cutting position and a second cutting position, the means for shifting a longitudinal position of the blades includes a pivoting member extending though an opening in each of plurality of parallel blades.

A surgical knife comprising:

• a plurality of parallel blades;
• means for securing the blades to the base;
• means for shifting a longitudinal position of the blades with respect to each other and with respect to the base between a first cutting position and a second cutting position;
• and
• wherein the means for securing the blades to the base and the means for shifting a longitudinal position of the blades comprise a threaded member pivotally connected to the base of the handle and extending through openings in the blades.

A method of removing hair-laden tissue from a donor for transplantation to a donee, comprising the steps of:

• providing a multiple bladed surgical knife having a base, a plurality of blades, means for securing the blades to the base, and means for shifting a longitudinal position of the blades with respect to each other and with respect to the base;
• determining a hair angle between a direction of hair growth and a line perpendicular to a scalp;
• shifting the blades to a plurality of positions whereby a line formed by a forward end of each of the blades is orientated at a blade angle with respect to a line perpendicular to a longitudinal axis of the knife, the blade angle being substantially equal to the hair angle;
• inserting the blades into the scalp at a direction parallel to the direction of hair growth;
• translating the blades through the scalp;
• and
• removing a plurality of hair-laden tissue strips from the scalp.
