Abstract

Abstract A dermatome for cutting thin organic tissue sections for transplanting, the dermatome comprising a thin resilient cutting band provided with a cutting surface disposed along a longitudinal edge of the cutting band. A T-shaped support member positions the cutting surface of the cutting band relative to the tissue sections. The head portion of the support member holds portions of the cutting band to determine the width of the cut tissue sections, the cutting band being held in a loop-like arrangement with the cutting surface extending along a bight portion thereof. The head portion of the support member also includes a guide element for determining the depth or thickness of the cut tissue sections, the guide element being disposed between the spaced apart cutting band portions and being spaced a preselected distance from the bight portion. Attachment elements are provided on the support member to permit connection of the support member to a handle member. The cutting band may be removably connected to the support member, or the cutting band may be integrally secured to the support member in a non-removable arrangement.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 195 words
A dermatome comprising a thin resilient cutting band provided with a cutting surface disposed along a longitudinal edge of said cutting band, a support member having a transverse head portion for positioning said cutting surface of said cutting band, said head portion including holding means for maintaining a first end of said cutting band in a predetermined spaced apart relationship to a second end of said cutting band to provide a loop-like arrangement for said cutting band with said cutting surface extending along a bight portion of said loop-like arrangement, said predetermined spaced apart relationship determining width of cut, said first and second cutting band ends extending through a surface of said head portion and being disposed within said head portion, said bight portion being spaced from said surface of said head portion in a facing relationship with said surface of said head portion, said support member including guide means for determining depth of cut, said guide means being disposed between said first and second cutting band ends and spaced a preselected distance from said bight portion, and said support member including attachment means to permit connection of said support member to a handle member.
Claim 2
Dependent Claim 195 words
A dermatome comprising a thin resilient cutting band provided with a cutting surface disposed along a longitudinal edge of said cutting band, a support member having a transverse head portion for positioning said cutting surface of said cutting band, said head portion including holding means for maintaining a first end of said cutting band in a predetermined spaced apart relationship to a second end of said cutting band to provide a loop-like arrangement for said cutting band with said cutting surface extending along a bight portion of said loop-like arrangement, said predetermined spaced apart relationship determining width of cut, said first and second cutting band ends extending through a surface of said head portion and being disposed within said head portion, said bight portion being spaced from said surface of said head portion in a facing relationship with said surface of said head portion, said support member including guide means for determining depth of cut, said guide means being disposed between said first and second cutting band ends and spaced a preselected distance from said bight portion, and said support member including attachment means to permit connection of said support member to a handle member.
Claim 3
Dependent Claim 67 words
A dermatome as claimed in claim 1, wherein said support member includes a body portion, said body portion extending from central part of said head portion to provide a T-shaped arrangement, said first and second end of said cutting band being disposed on opposite sides of said body portion, said guide means being disposed along said head portion, said attachment means being disposed on said body portion.
Claim 4
Dependent Claim 23 words
A dermatome as claimed in claim 1, wherein said holding means provide for said cutting band ends being molded in said head portion.
Claim 5
Dependent Claim 41 words
A dermatome as claimed in claim 1, wherein said attachment means includes at least one pin element to permit said support member to pivot relative to the handle member to a desired angular position before being fixed to the handle member.
Claim 6
Dependent Claim 22 words
A dermatome as claimed in claim 1, wherein said guide means extends outwardly further than said cutting surface to support said dermatome.
Claim 7
Dependent Claim 25 words
A dermatome as claimed in claim 1, wherein said holding means integrally secures said cutting band ends to said support member in a non-removable arrangement.
