Is there any harm in ultrasonic scalpel beauty treatment? What is the principle of ultrasonic scalpel?

The beauty knife is a relatively advanced technology. The main principle of the beauty knife is to help repair our skin wrinkles, tumors, and tissue problems. However, ultrasonic knife beauty can also have some harmful effects. Everyone should understand the principle of the ultrasonic knife and what it is used to treat, so that they can know how to deal with the ultrasonic knife. Although the ultrasonic knife has certain cosmetic effects, its more important function is to treat some diseases.

Indications

Indications: Mainly suitable for various tumors in the abdomen, pelvis and body surface. Mainly include: pancreatic cancer, liver cancer, benign and malignant tumors of kidney and adrenal gland, gastric cancer, rectal cancer, colon cancer, prostate cancer, prostate hyperplasia, bladder cancer, uterine cancer, uterine fibroids, ovarian cancer, various abdominal and pelvic metastatic cancers, etc.

Application Principle

The ultrasonic knife has a tumor recognition system that can accurately detect the location and size of the tumor, and then transmit the image information to the computer. After receiving this information, the computer can automatically lock the tumor. Under the control of the computer, the ultrasonic wave can pass through the normal tissue of the human body without any damage to the tumor tissue, killing tumor cells without damaging the normal tissue around the tumor.

The application principle of the ultrasonic scalpel is to convert electrical energy into mechanical energy through a special conversion device. Through high-frequency ultrasonic vibration, the water in the contacted tissue cells is vaporized, the protein hydrogen bonds are broken, and the tissue is coagulated and then cut. The application of ultrasonic scalpel in laparoscopic surgery has obvious advantages.

A comparative study by scholars found that the coagulation time of monopolar electrosurgery and ultrasonic scalpel was 1, 5, and 9 seconds, and the range of tissue damage was 2.5, 6, and 7 mm and 0.8, 2, and 3.5 mm respectively. The ultrasonic scalpel caused much less damage to the surrounding tissue than the electric scalpel. Its precise cutting effect allows it to safely separate and cut near important organs and large blood vessels. The less smoke and eschar makes the laparoscopic surgery field of view clearer and the operation time shorter. The lack of electric current passing through the human body makes the surgery safer and reduces the occurrence of complications.

The treatment of intra-abdominal patchy adhesions and mesentery, which was difficult and time-consuming using electric scalpels, has become easier with the advent of ultrasonic scalpels, which reduces the difficulty of the operation and the amount of intraoperative bleeding, and is more in line with the tumor-free principle of tumor surgery.

When in use, the temperature of the ultrasonic knife head is lower than 80°C, the surrounding propagation distance is less than 5 microns, and it rarely produces smoke and eschar, no electric sparks, and no electrophysiological interference to the body. Compared with the electric knife commonly used in ordinary surgery, the ultrasonic knife has the advantages of precise cutting, firm hemostasis, and strong controllability. It is safer and more effective, and therefore more advanced.
