Product Description

 

The main mechanism of the ultrasonic scalpel is the output of the electrical signal from the host. The transducer uses the electrostrictive effect or magnetostrictive effect to convert the ultrasonic electrical energy into mechanical energy to generate high-frequency vibration, which is driven by the amplification and coupling of the horn. The knife head works and spreads energy to the local tissues of the human body, so as to achieve the purpose of surgical treatment [2]. The structure of the handheld part of the ultrasonic scalpel is shown in the figure.
Structure of ultrasonic scalpel handheld part
The amplitude of the ultrasonic cutter head is very small, but the vibration frequency is extremely high, resulting in a high instantaneous acceleration. Therefore, when performing soft tissue cutting, the affected part can be cut quickly without damaging the surrounding tissues.
After the ultrasonic blade touches the human body, it will also produce micro-acoustic flow effect, cavitation effect, thermal effect and hemostatic effect [3]:
1. Micro-acoustic flow effect: It is manifested as the ultrasonic vibration makes the affected tissue become homogenous, and the fat in the tissue will escape when the cutting temperature rises. Under the action of the vibration of the cutter head, the liquefied tissue can form a micro-acoustic flow near the cutter head, and the shear stress associated with the micro-acoustic flow will destroy the tissue cells.
2. Cavitation effect: the volume of a large number of microbubbles (cavitation nuclei) in the tissue fluid is rapidly expanded and ruptured, causing the separation of the tissue level to achieve the effect of anatomical separation.
3. Thermal effect: due to the high frequency and high energy of ultrasonic waves, part of the energy is converted into heat energy when absorbed by the medium, which causes the temperature of biological tissues to rise.
4. Hemostatic effect: When the ultrasonic scalpel is working, the high-frequency oscillating blade contacts the tissue fluid or blood, which produces a strong cavitation effect. The thermal effect of the bursting of a large number of cavitation bubbles causes the nearby proteins to break and coagulate and block the blood vessel fracture. Emergency stop bleeding; at the same time, whether it is vibration friction or cavitation effect when the scalpel cuts, it will cause a certain degree of heating of the acting body, which can increase the activity of thrombin in the blood near the area, thereby accelerating the coagulation reaction process.

Piezosurgery is an innovative osteotomy technique using piezoelectric ultrasonic vibrations. Ultrasonic vibrating instruments for cutting mineralized tissue have been reported since the 1950s In 1988, Italian oral sugeon, Tomaso Vercellotti, developed a piezoelectric osteotomy device, which provided the opportunity for the widespread clinical use of piezosurgery Currently, piezoelectric devices are used widely for osteotomies, such as maxillary sinus lift, impacted mandibular third molar extraction, and bone grafting, in the field of oral and maxillofacial surgery.
The major advantage of piezosurgery is its selective cutting of mineralized bone. Frequencies higher than 50 kHz are needed to cut soft tissues. The piezoelectric device is designed to produce ultrasonic microvibrations of 60-210 μm at a frequency of 25-30 kHz. Thus, piezoelectric devices, different from conventional rotary instruments and microsaws, are able to cut only mineralized tissues. Therefore, piezosurgery can reduce considerably the risk of damage to adjacent soft tissues, such as blood vessels, nerves, and mucous membranes, in cases of osteotomy. Other advantages of piezosurgery include reduction of overheating resulting from the generation of a cavitation effect and better visibility of the surgical area due to less bleeding. Moreover, use of piezosurgery for extraction of the impacted mandibular third molar was reported to produce less facial swelling and trismus postoperativily compared to that of rotary osteotomy. Recent studies on the healing of bone defects experimentally created by piezosurgery demonstrated no difference in the newly formed bone volume and the healing process between piezosurgery and conventional osteotomy techniques. Meanwhile, piezosurgery was shown to have a longer surgical time than conventional osteotomie.
