The L-C anorectal comprehensive treatment instrument is a more advanced treatment instrument, and now through a large number of clinical cases comparing the clinical comprehensive effect of L-C anorectal comprehensive treatment instrument and traditional operation in the treatment of anorectal diseases: operation time, cure rate, postoperative complications, postoperative quality of life, etc., it shows that in the treatment of anorectal diseases, the new anorectal treatment instrument has the advantages of easy operation, short operation time, less pain during treatment, less complications and higher cure rate than traditional operation. The new anorectal treatment instrument has obvious advantages in terms of simpler operation, shorter operation time, less pain during treatment, less complications and higher cure rate than the traditional operation. This can improve the cure rate, reduce intraoperative and postoperative pain, and improve the quality of life of patients after surgery. The cure rate of anorectal diseases (especially internal and external hemorrhoids) treated with multifunctional treatment instrument is significantly higher than that of traditional surgery, and the postoperative complications are less. With the deepening of the concept of minimally invasive, the current auxiliary treatment instruments for anorectal diseases are: laser, infrared treatment instrument, radio frequency treatment instrument, direct current treatment instrument, and L-C anorectal multifunctional treatment instrument. Among the above methods, except for laser, infrared, radio frequency and direct current are suitable for early internal hemorrhoids with bleeding as the main symptom, but the effect is poor, and it is not suitable for external hemorrhoids, laser is suitable for all kinds of hemorrhoids treatment, but because it is an exogenous conductive heat, it is easy to cause local edema, charring, infection and larger trauma after treatment, and easy to bleed after surgery. The effect of traditional surgery is also not good. The LC type multi-functional anorectal treatment instrument works on a more scientific principle, it is the use of high frequency capacitive field heat generation principle, in the shortest possible time to reach the treatment site, so that the hemorrhoid root tissue dry, not carbonized, good vascular closure and other advantages, has the characteristics of thermal orientation, good control, strong limitations, only limited to the role of the site and the neighboring tissues have obvious temperature difference boundary, will not hurt the neighboring tissues, and the role of this heat It can increase the exudation of fibrin and prothrombin in the treatment site within 3~5 d. Together with the factors such as vascular occlusion and adhesion, the possibility of re-bleeding after treatment is extremely small and no other side effects will be produced. From clinical observation, the treatment instrument is superior to laser, microwave, infrared, radio frequency and direct current in the treatment of anorectal diseases, thus having the advantages of less postoperative complications, high life treatment and low hospitalization rate. It is one of the best methods to treat anorectal diseases.
