In recent years, Tyco’s new Ligsure system can be used to treat various types of hemorrhoids, intestinal polyps, etc. with less trauma, significantly reduced post-operative pain, and some patients can be treated on an outpatient basis without hospitalization, reducing the burden on patients. The following is the company’s description of the product: Ligation Speed Cutting and Closure System Using Wiley’s patented Instant ResponseTM Technology and Smart GeneratorTM Technology, the high frequency electrical energy output, combined with the pressure of the vascular jaws, causes the collagen and The high frequency electrical energy output, combined with the vascular jaw pressure, causes the melting and denaturation of the collagen and chain proteins in the human tissue and the fusion of the vessel wall to form a transparent band, resulting in permanent lumen closure. The advantages of the ligation speed cutting closure system are: 1. the ability to close vessels up to 7 mm in diameter; 2. the closure of vessels contained in tissue bundles without tissue separation; 3. the formation of a closure band that can withstand pressures exceeding three times the normal human systolic pressure; 4. faster closure than the use of sutures; 5. no foreign body remains after closure; 6. no visible crust formation during closure; 7. the heat transfer distance during closure is Short, average 1,5-2mm; 8. In some procedures, a certain degree of cost savings compared to the use of sutures.
