Disposable Laparoscopic Surgical Instruments Sound Reach Ultrasonic Surgica Scalpel

When it comes to ultrasound, you may be familiar with it. It's easy to think of ultrasound. B-ultrasound is a diagnostic device that uses low-intensity ultrasound. Ultrasonic knife is full name of "ultrasonic cutting hemostatic knife", technical name of high intensity focused ultrasound, in the late 1980s began to be used in ophthalmology and neurosurgery, mainly for fine segmentation. With the rapid development of minimally invasive surgical technology, ultrasonic knife, as a new type of surgical instrument, has the characteristics of shorter operation time, less bleeding, less smoke in the process of use, clearer vision and so on, especially in the tumor resection has become a widely used medical surgical scalpel.

The principle of the ultrasonic knife is to convert the electric energy of the generator into ultrasonic mechanical energy through the converter. The ultrasonic frequency generator is used to make the metal cutter head carry out mechanical shock at the ultrasonic frequency of 55KHz, and the tissue cells contacted by the cutter head will be instantly hydrated, and the protein hydrogen bond will be broken and the cells will disintegrated, thus cutting the tissue and achieving coagulation and hemostasis at the same time. Compared with the traditional electrosurgical knife, the tissue temperature of the cutting site of ultrasonic knife is less than 80℃, the energy propagation distance is less than 0.5mm, and the damage to the surrounding tissue is less. With precise cutting effect, it can be safely separated next to important organs and large blood vessels. Only a small amount of vaporizing water mist is produced in the process of use, no smoke, no eschar, clear vision; No current through the recipient, can be safely used for cardiac pacemaker; The coagulation effect is good, can safely coagulate arteries and veins below 3.0mm, and can even coagulate vessels as thick as 5.0mm, significantly reduce the bleeding and oozing of the wound during the operation, shorten the operation time, and reduce the occurrence of complications.
