Abstract
A dermatome blade assembly includes a first part defining a cutting edge and a second part adapted for reciprocating attachment with a dermatome. The second part is made from a light weight bearing like plastic to minimize vibration and resistance to movement for the blade assembly during operation.
Claims6
A dermatome blade assembly for selective attachment to the dermatome, the blade assembly comprising a two part unit,, a first part of the unit defining a cutting edge adapted for engagement with skin for removal of the latter in response to the reciprocating movement of the first part, the second part being fixedly coupled to the first part at all times and comprising a light weight member adapted for engagement with a reciprocating drive member of the dermatome, the second part further including means cooperating with the dermatome to substantially maintain the reciprocating movement in a parallel direction to the cutting edge and the second part forming a bearing surface movably engaging the dermatome while retaining the first part slightly spaced from the dermatome, the first part forms a first side engageable with the second part and at least one tab extends from the second part through an opening in the first part to form an enlarged head on top of a second side of the first part, and the second part defines at least one post extending in an opposite direction to the one tab and engageable with the dermatome.
A dermatome blade assembly comprising a first part forming a cutting edge and a second part secured to the first part to form a unitary assembly for selective attachment to a dermatome, the second part is made from a light weight plastic defining a bearing surface slideably engageable with the dermatome, integral tabs extend outwardly from one surface of the second part to secure the first part to the second part, and at least one post extends outwardly from an opposite surface of the second part to cooperate with the dermatome.
A dermatome and blade assembly including at least two parts, a first part of the blade assembly defining a cutting edge adapted for engagement with skin for removal of the latter in response to reciprocating movement of the first part, the second part being coupled to the first part and comprising a light weight member adapted for engagement with a reciprocating drive member of the dermatome, the second part further including means cooperating with the dermatome to substantially maintain the reciprocating movement in a parallel direction to the cutting edge, the second part forming a bearing surface movably engaging the dermatome while retaining the first part slightly spaced from the dermatome, and the dermatome defining a recess to receive the second part to control the direction of movement for the reciprocating two part unit.
