From the anatomical structure of human pelvic floor, vagina is mainly composed of muscles and related ligaments. Weakness or deficiency of sphincter around vagina will lead to increase of vaginal cavity space and relaxation of vaginal orifice. Understand the pathogenesis of vaginal relaxation, you can understand how to treat it. It's not effective for compact laser therapy. Laser power can only act on mucosa or submucosa, and has no therapeutic effect on muscle. If the energy is too high, it is easy to damage the mucosa. Once the mucosa is destroyed, there will be more serious gynecology. At present, the problem of vaginal relaxation can be improved and treated by surgery or exercise. Minimally invasive 3D biological belt tightening of private parts is mainly aimed at patients with mild to moderate relaxation, mainly for vaginal cavity and vaginal orifice tightening. Minimally invasive 3D biological belt tightening of private parts adopts minimally invasive surgery, and regenerative tissue biological belt is implanted in the sphincter and vaginal orifice of the posterior wall of vagina to establish ligament for the relaxed sphincter and vaginal orifice, restore the elasticity of sphincter and enhance muscle strength, so as to realize effective tightening of vagina. If it is more than severe relaxation, traditional posterior wall compression surgery can be used for compression. You can go to the local gynecological clinic, gynecological hospital or plastic surgery hospital to find out.
