Abstract
A light weight, portable, hand held power actuated hair transplant plug cutting device is capable of making either simultaneous multiple punches or a single punch in the scalp of a patient. A single shaft member with removable cutting tip extends through one wall of the housing unit of the device, while a plurality of shaft members with removable cutting tips extends through the opposite wall of the housing unit. Actuation of the power drive causes rotation of both the single shaft member and the plurality of shaft members so that only the single cutting device is needed to make all of the punches required for the hair transplant operation. Tools are provided for placing and removing disposable cutting tips on and from the shaft members.
Claims5
A power driven multiple punch cutting device for making either single or multiple punches in the scalp of a patient undergoing a hair transplant operation, comprising
- a housing having a plurality of apertures in a first wall thereof and a single aperture in a second wall thereof opposite to said first wall;
- a plurality of shaft members extending through said housing from said second wall to said first wall and perpendicularly outward from said first wall through said plurality of apertures;
- a single shaft member extending through said housing from said first wall to said second wall and perpendicularly outward from said second wall through said single aperture;
- first means for rotatingly driving said single shaft member comprising a first bevel gear connected to said power source and a second bevel gear connected to said single shaft member and driven by said first bevel gear;
- second means for rotatingly driving each of said plurality of shaft members comprising a first gear train adjacent said first wall and a second gear train adjacent said second wall wherein said first and second gear trains comprise a plurality of spur gears, one of which spur gears in said first gear train is driven by an idler gear and causes rotation of the remainder of the plurality of spur gears which in turn rotatingly drive said plurality of shaft members;
- means for transmitting the driving power from said first drive means to said second drive means comprising a first spur gear connected to said single shaft member spaced from said second bevel member and adjacent said first wall, and said idler gear adjacent said first wall and driven by said first spur gear;
- a power source for driving said first drive means, whereby driving of said first drive means by said power source causes rotation of said single shaft member and simultaneous rotation of said plurality of shaft members through said power transmitting means and said second drive means, respectively;
- and
- cutting heads attached to the free ends of each of said single shaft member and said plurality of shaft members;
- whereby said device is capable of making either simultaneous multiple punches through the cutting heads attached to the plurality of rotating shaft members or a single punch through the cutting head attached to the single rotating shaft member.
