Abstract
A device is disclosed for simultaneous cutting and cauterizing of tissue. The device comprises a cutting edge of a blade. The blade defines a channel within the blade wherein the outlet end of the channel is near the cutting edge. A catalyst is disposed near the outlet end. The channel carries a gaseous mixture to the catalyst where the mixture reacts in the presence of the catalyst and generated heat. The heat generated cauterizes blood vessels as the blade cuts through tissue.
Claims52
An apparatus for cutting comprising:
- a blade comprising a cutting edge and defining at least one primary channel, each primary channel having an inlet end and outlet end with the outlet end proximate to the cutting edge;
- and
- a catalyst disposed proximate to the outlet end of each primary channel.
A cauterizing scalpel to simultaneously incise and cauterize tissue comprising:
- a blade holder;
- a blade having at least one cutting edge, an edge distal to the cutting edge for connection to the blade holder for holding the blade;
- a conduit having an inlet end and an outlet end, wherein the inlet end is connected to the blade holder, and the conduit is held in a defined position relative to the blade;
- and
- a catalyst disposed proximate to the outlet end of the conduit.
An apparatus for remote cutting comprising:
- a shaft member having a longitudinal axis and first and second ends;
- a blade operably affixed to the first end of the shaft member, having at least one cutting edge and defining at least one channel formed therein, wherein the channel has an inlet end and an outlet end with the outlet end proximate to the cutting edge;
- a catalyst disposed proximate to the channel outlet end;
- and
- a conduit in fluid communication with the channel inlet end in the blade.
An apparatus for remote cutting comprising:
- an outer cylindrical conduit defining an inner cylindrical surface and having a longitudinal axis, an open first end, an open second end, and at least one notch disposed in the open first end;
- a shaft member having a longitudinal axis and first and second ends, wherein the shaft member is adapted to move within the outer cylindrical conduit;
- a blade operably affixed to the first end of the shaft member having at least one cutting edge wherein the cutting edge is positioned to slide over the notch;
- a gas conduit defining a channel for carrying a gas mixture, and having an inlet end and an outlet end wherein the outlet end is proximate to the notch of the outer conduit;
- and
- a catalyst disposed proximate to the outlet end of the gas conduit.
A cutting apparatus comprising:
- a blade having a first end and a second end opposite the first end and a cutting edge disposed therebetween, and defining at least one channel formed therein wherein each channel has an inlet end and outlet end with the outlet end proximate to the cutting edge and the inlet end proximate to one of the first or second ends;
- a pair of arms affixed to the first and second ends of the blade;
- and
- a catalyst disposed proximate to the outlet end.
