摘要:
A multi-shaft apparatus for incising a substrate of soft resilient material such as a body tissue. The incising apparatus includes two or more incision shafts each having a distal edge. The shafts are not affixed to each other and are allowed to slide against each other to drive the distal edges alternately against the substrate to incise the substrate. In the case of incising a body tissue, such alternate motion would result in less pain to the patient than a puncture resulting from a sharp jab by a sharp shaft of similar size to the shafts.
