Abstract

Improvements in the construction of surgical scalpels, characterized by comprising a box; a motor device mounted on said box; an elongated external fixed tubular scalpel attached to one end of said box, whose external scalpel has an axial bore therethrough, the distal end of said scalpel being closed and less than half the diameter of said external scalpel being emptied at said distal end to form a cutting edge opening in said scalpel through which tissue can be aspirated; an elongated internal tubular scalpel mounted on said bore to effect at least partial rotation about its axis, the distal end of said internal scalpel being closed and a part of the diameter thereof being emptied at said distal end to form an opening, coinciding said opening of said internal scalpel with said opening of the external scalpel; transmission means connected to said motor device for effecting said rotation of said internal scalpel, whose transmission means comprises a hollow driving shaft, the interior of which communicates with the interior of said internal scalpel; a source of emptiness; means for supplying a vacuum from said source to said interior of said driving shaft and from this to said interior of said internal scalpel; and means for controlling the supply of vacuum to said interior of said conductive shaft whereby the tissue sucked into said opening of said internal scalpel by the action of said vacuum is cut by the rotation of the internal scalpel inside said said bore. said external scalpel and against it.
