Definitions

  • the present invention concerns the field of general medicine, oral medicine and veterinary medicine and all procedures where precise cutting of organic cells and/or tissue, organic and non-organic flexible tissue and/or fibres is necessary.
  • Presently (scalpel or "Stanley-Knive") blades used in medicine and other cutting professions are manufactured on a large industrial scale according to an internationally standardized number system to identify the shape and the size of the scalpel. Every cutting performed with these scalpel blades suffers in its precision from the friction of the scalpel blade to the cutted organic or fibre tissue causing a tearing, distorting and displacing effect to the cutted site when the cutting site is not fixed properly or the tissue layers are too many or too thick. This is caused by the constant and direct contact of the scalpel blade to the cutted tissue during the process of cutting leading to the distortion of the tissue and therefore reducing the precision of the cut.
  • various lasers e.g. CO2, Nd:YAG, Er:YAG, Ho:YAG, Diode, Excimer etc.
  • CO2 nuclear-driven laser
  • Nd:YAG, Er:YAG, Ho:YAG, Diode, Excimer etc. can be used but with a more or less strongly expressed heating and coagulating effect to the cutted organic molecules and therewith on a micro- and macroscopic scale to the border of the performed cut thus enlarging the width of the cut, decreasing it ' s precision and destroying the integrity of organic cells and fibres in a relatively large area on a microscopic scale.
  • Non-touch or “touchless”- cutting procedure by projecting bundled coherent electromagnetic waves ("coherent light”) from the infrared to the ultraviolet range to the cutting site producing heat and thus disrupting the integrity of organic cells and/or fibres.
  • coherent light bundled coherent electromagnetic waves
  • the present invention is a new approach to cutting by projecting sonic/ultrasonic oscillation energy via conventional scalpel blades and/or especially shaped thin and light steel and/or ceramic blades to organic cells, organic and non-organic fibres and/or fibre-tissue with or without a cooling irrigation by various liquids transported to the cutting site by an internal and/or external irrigation channel in or to the device in order to allow cutting procedures with or without thermal side effects such as coagulation of biological tissues and minor blood vessels to achieve hemostasis.
  • Such the SONO-scalpel can be used in three modes: a) normal cutting with scalpel blade, b) sound/ultrasound activated cutting WITH heat-coagulating (hemostatic) effects on organic tissues, c) sound/Ultrasound activated cutting WITHOUT heat-coagulating effects on organic tissues by cooling the cutting blade with cooling liquids transported through an internal irrigation channel and/or an external irrigation hose aimed to the cutting edge of the blade.
  • the invention embodies an insert/tip with rigidly or removeable attached scalpel blades in international standard shapes or specialized designs for specific surgical and/or cutting procedures that can be attached to any sound and/or ultrasound generator by a connector or can be produced with this generator "in one piece”.
  • the present invention is a new approach to cutting by projecting sonic/ultrasonic oscillation energy via conventional scalpel blades and/or especially shaped thin and light steel and/or ceramic blades to organic cells, organic and non-organic fibres and/or fibre-tissue with or without a cooling irrigation by various liquids transported to the cutting site by an internal and/or external irrigation channel in or to the device.
  • the cutting and heating effect of oscillating liquids and/or gasses resembles somehow the disrupting effect of coherent electromagnetic waves ("lasers”) from the infrared to ultraviolet range of electromagnetic frequency in organic molecules on the atomic scale, the disruption of organic cells by heating the inner-cell liquids and organic fibres by mechanically and thermally disrupting the structure of the long molecules on the microscopic and macroscopic scale.
  • laser waves coherent electromagnetic waves
  • the physical effects of coherent electromagnetic and sonic/ultrasonic waves are different on the atomic level on the basis of mere physics (electromagnetic waves: electromagnetic interaction with electrons, ultrasonic waves: mechanical interaction with atomic binding forces i.e. Van der Waal-forces)
  • the microscopic and macroscopic effects are somehow similar in organic molecules, cells and fibres (disruption of organic molecules and cells).
  • the present invention reduces and/or annihilates the unwished physical side effects of both conventional cutting metal and/or ceramic blades and lasers or gives the user the choice to use the side effects selectively:
  • Metal and/or ceramic blades oscillating in the range of 10.000 - 60.000 Hz at an amplitude of 0,0001 to 1 Millimeter need only slight contact to the cutting site even when penetrating into tissue layers more than lmm and thus causes no distortion of the cutted tissue by mere continous friction between the blade and the tissue similar to the "non- contact"- or "touchless”- cutting procedure using electromagnetic waves (i.e.
  • the metal and/or ceramic blades can be cooled by water spray applied to the blade and the cutting site.
  • TKW-Sono-Scalpel can be used in three modes:
  • a cooling liquid spray water, physiological or other saline solutions, other heat absorbing liquids at different temperatures from liquid CO2 over ice-water to room-temperature liquids
  • the present invention combines all advantages of a regular scalpel/cutting blade and electromagnetic cutting devices (lasers) and annihilates the disadvantages of these devices or utilizes them selectively if necessary.
  • the present invention can be manufactured in a way that it connects to and can be coupled to mechanically to all sonic/ultrasonic generators presently available on the market (i.e. mechanical, electromagnetic, piezoelectric sound and ultrasound generators).
  • the present invention is meant to be used in:
