Definitions

  • the invention relates to an inexpensive and portable Veterinary Ultrasonic Blade that can be used in trimming the horns of animals, in operations in cattle such as rumenotomy, caesarean section and displaced abomasum surgery requiring the incision of cattle skin, in breaking down animal carcasses and breaking bones, in autopsies of animals in veterinary hospitals, in treatment of foot diseases and in foot care.
  • Ultrasonic cutting technique is used today in many areas such as healthcare, dentistry, food, metallurgy, marble processing and textile. This technique is used in all cases where fast, clean and smooth cutting is desired.
  • ultrasonic cutting systems vary according to purpose of use, they can operate at sound frequencies between 20 kHz and 40 kHz, which are inaudible to the human ear, and the amplitude can also be adjusted.
  • electricity By applying electricity to the piezoelectric crystals contained in ultrasonic devices, sound waves are produced that are inaudible to the human ear.
  • These ultrasonic waves create thermoplastic erosion with the cavitation effect on the surfaces they come into contact with, creating molecular ruptures in the application site. Since this phenomenon occurs at the micronic level, very clean and smooth cuts can be achieved.
  • Ultrasonic cutting technique is generally used in materials with high rigidity and endurance.
  • ultrasonic blades which are also used in humans in cutting sensitive organs such as veins and tendons.
  • Ultrasonic devices used for cautery in medicine create a 55.5 kHz vibration at the tip of the cautery to create coagulation and perform cutting. It is known that ultrasonic cautery leads to less tissue damage and better postoperative results.
  • the Veterinary Ultrasonic Blade which is the subject of the present invention, consists of an ultrasonic generator, transmission cable (7), piezoelectric transducer (8), cutting implement (9) and foot pedal.
  • the ultrasonic generator is a power source that receives 220 V, 50-60 Hz, 8 A electrical input, and through the amplifier circuit inside, generates automatically adjusted electrical output in the range of 250-350 V, 15000-100000 Hz, and 2-4 A according to the strength of the material.
  • On the ultrasonic generator there is voltage indicator (1 ), current indicator (2), frequency indicator (3), error indicator (4), power switch (5) and ultrasonic operating switch (6).
  • Transmission cable (7) is an intermediate element used to transmit the electrical output generated by the ultrasonic generator to the piezoelectric transducer (8).
  • the ultrasonic conduit consists of two positive and negative pins, and the transmission cable (7) transmits the electrical output received from the ultrasonic generator to the piezoelectric transducer (8) with a two-pin socket.
  • Piezoelectric transducer (8) is made up of inorganic quartz material consisting of lead, zirconate and titanate components. It has crystal structure and when an electric current is applied on it, it expands and contracts, thus creating mechanical movement. The mechanical waves that occur in the environment during these movements create sound waves. When the frequency of these sound waves exceeds 20 kHz, ultrasonic sound waves occur.
  • the cutting implement (9) has a body made of steel material that magnifies and focuses the intensity of sound waves (sound transmission 6000m/s), and a tip made of light, hard, highly impact-resistant and corrosion-resistant titanium material.
  • the mechanical waves created by the piezoelectric transducer (8) are transmitted onto the amplifier body and accelerated, and the pressure is increased.
  • the waves passing from there to the titanium tip with pressure create micron-sized pressure movements on the sharp surface. Micron-sized deformations occurring on the material allow it to be cut rapidly.
  • the foot pedal includes a foot-operated pedal switch and a 4-pin socket connection to control the ultrasonic output, allowing the operator who uses both hands during the operation to command the device.
  • Two of the pins serve as ultrasonic output switches and the other two as cooling fan connections.
  • the foot pedal socket and the transmission cable (7) are connected to the specified places on the ultrasonic generator.
  • the other end of the transmission cable (7) is connected to the socket inlet on the cutting implement (9).
  • the power switch (5) of the ultrasonic generator is turned to "on" position.
  • the ultrasonic blade is activated as soon as the foot pedal is pressed.
  • the ultrasonic effect is transmitted to the blade.
  • the ultrasonic effect stops as soon as the pedal is released.

Abstract

L'invention concerne une lame ultrasonore vétérinaire peu coûteuse et portative qui peut être utilisée pour le parage des cornes d'animaux, lors d'opérations pratiquées sur du bétail telles qu'une ruminotomie, une césarienne et une chirurgie de déplacement de la caillette nécessitant l'incision de la peau du bétail, lors de la casse de carcasses animales et de la casse d'os, lors d'autopsies d'animaux dans des cliniques vétérinaires, lors d'un traitement de maladies du pied et lors de soins du pied.
