Superior Rex Medical Device Ultrasonic Transducer
Ultrasonic Transducer converts electrical energy from the main generator mechanical movement. Handle with ultrasonic receiver connected to the amplifier, the amplitude of the latter amplification produced by transducer handles, energy transfer and movement to the instrument. Transducer lever handle also provides equipment connected to the host hand control signal.
System’s Generator drive transducer handle to the device to a frequency of 55.5 KHz, 60-100 microns of longitudinal vibration amplitude, the ultrasonic vibration can under the pressure of the right to have good cutting ability, at the same time this kind of vibration with blood and tissue protein coagulation closed small blood vessels, cutting/stop the bleeding. Tissue and blood clotting during the vibration coupling, the coupling vibration within the organization protein, fusion degeneration clot formation, to achieve closed well organized, namely solidification/stop the bleeding.
1) The first step is hollowing out cutting and separation. When blade vibration, it instantly converts pressure within the cell and groups of moisture to evaporate at low temperatures, cell rupture, precise cutting and separation. In addition, the mechanical energy hollowing out moisture evaporation to expand organization, organizational level. The "hollowing out" effect does not destroy the organization, and improve visibility when cutting.
2) In the second step, by 60-110 microns amplitude vibration of 55500 times per second surface provides the real "cold cutting" of the cutting tools. Knife edge by excessive extension organizations make it beyond the elastic limit to cut (just like that is broken too stretched rubber band), from a micro point of view, which is interrupted its molecular bonds.
Coagulation/Stop the bleeding
Ultrasonic scalpel by mechanical forces, make the organization produces high frequency vibration, friction between the internal cells to generate heat, which break protein hydrogen bonding, make protein denaturation. When the equipment surface cutting sharp, large organizations will be bleeding, when the pressure on the face them with a blunt knife cutting and coagulation, not bleeding, and effective working time brief (2-3 seconds). For now, you can safely use ultrasonic cutting in clinical on 5 mm cutting and coagulation of blood vessels.
Thermal effect and hollowing out effect
Basic thermology shows that under the short of energy by the organization by the heat resulting from the pressure and friction (is limited to no more than 80 ℃ ( personal communication, R.
Anderson, MD, Wellman that Massachusetts General Hospital). Such organizations because of a lack of moisture and drying and coking can be reduced to a minimum. The highest temperature limits can reduce thermal damage to a minimum. The minimum thermal damage may explain why the same electric knife (66%) or laser knife (77%), compared to the use of ultrasonic scalpel in pigs in cavity mirror cholecystectomy, postoperative adhesion of liver bed decreased significantly.
When the blood vessel wall of solidification, the solidification method makes ultrasonic scalpel have more advantages than the electric knife. When using electric knife, due to the constant increase of the contact surface led to a decline in electricity density, so that the blood vessels are usually not obvious condensation. Has a great deal of heat, blood vessels in the blood can seep. This makes blood vessels side before the other side of the solidification, and result in contact with the electric knife, hemal wall hole of bleeding. Ultrasonic scalpel, by contrast, rely on the pressure and the organization's biggest energy to closed vessels. In that case, blood vessels will be with the contact surface of the cutting tools in the case of no bleeding closed.
