MINIMALLY INVISIBLE TECHNIQUE VAGINA OPENING PLASTY AND ANUS REINFORCEMENT Russian patent published in 2018 - IPC A61B17/42 A61B17/04 

FIELD: medicine.

SUBSTANCE: at least one jagged cylindrical suture thread is used, jags are divided into two groups relative to the median point of suture material that converge or deviate from each other, with sharp ends inclined respectively in the direction specified by the median point or in the direction of the respective ends to prevent thread traction, with each end of the suture thread specified equipped with a needle. During operation, a skin perforator is used to make cuts or holes in the working layer of female perineum, with at least one incisions cut located on the median suture of the perineum, and the other - on the superficial transverse muscle from the right or left side. Next, the specified at least one jagged suture thread is introduced through introduction of two needles at its ends, at different times, into the same initial hole with subsequent withdrawal from the same exit hole, thereby completing a thread motion path in different, superficial and deep, anatomical segments of the female perineum. During promotion, grooves or jags of the suture thread cross the soft tissue, cavernous bodies and muscle bundles of various vaginal, vulvar and perineal layers providing their connection and a support for them in the selected direction depending on the anatomical situation found in the vaginal, perineal and vulvar anatomical areas subject to connection. The two ends of at least one thread are tied together after it exits the same exit hole, then the loop is closed with a simple straight, reverse suture thread knot or multiple knots. The self-fixing cylindrical suture thread for surgical method implementation, with converging jags distributed spirally along the suture thread surface so that they are sequentially arranged on four generatrices spaced at an angle of 90°. At that, each notch on the suture material has three grades of microrelief or slicing, while the values of the cutting angles correspond to the values of the cutting blade, are selected in the range of 3° to 87° or 177° to 93° and are geometrically complementary.

EFFECT: method and thread can improve vaginal muscle tone, improve skin elasticity in this area, reduce the size of the vagina opening, and reduce the dilation or prolapse of the external sphincter.
