The embodiment of the invention provides a method for introducing the puncture guiding device for contracting the vaginal cavity, which comprises the following steps:
s1, opening an inlet A and an inlet B at the junction of the labia minora and the mucosa outside the vaginal opening, wherein the inlet A and the inlet B are positioned on the same horizontal line;
s2, puncturing the biological belt to the entrance B on the opposite side under the mucosa of the back wall of the vagina by the puncture guiding device;
s3, the biological belt is penetrated under the mucosa of the back wall of the vagina to the entrance of the opposite side A at the entrance B by the puncture guiding device, the biological belt is pulled and tightened at the entrance A, and the back wall of the vagina protrudes to form folds in the vaginal cavity to narrow the vaginal cavity;
and S4, tightening the biological belt to a preset tension and then suturing and fixing the biological belt on the deep tissue.
If the laxity is severe, the procedure can be used to make three passes of the puncture back and forth through the posterior wall of the vagina, which can contract the entire vagina and increase the number of folds.
The application method of the puncture guiding device for vaginal opening narrowing provided by the embodiment of the invention comprises the following steps:
s1, a puncture guiding device is used to pierce a first puncture on the side wall of the vaginal opening on one side and penetrate through the submucosa of the inferior semi-ring of the vaginal opening;
s2, guiding the first biological belt into a submucosal layer below the vaginal opening, and enabling the puncture guiding device to penetrate out of a second puncture on the side wall of the vaginal opening on the other side;
s3, another puncture guiding device is used to pierce a second puncture on the side wall of the vaginal opening on the other side, a tunnel is additionally made under the mucosa to the first puncture on the side wall of the vaginal opening on one side, and a second biological belt is introduced to penetrate through the submucosal tunnel; if necessary, a plurality of different tunnels can be formed, and biological belts are introduced to increase the range and tension of vaginal orifice narrowing;
s4, tightening the first biological belt and the second biological belt, fixing and sewing under the mucosa, and narrowing the external vaginal opening.
The application method of the puncture guiding device for repairing the superficial transverse perineal muscle provided by the embodiment of the invention comprises the following steps:
s1, determining the position of the broken muscle end at the middle of the vaginal opening and the anus;
s2, the biological belt is guided into the body through the puncture guiding device and penetrates out of the broken end of the muscle on the opposite side;
s3, leading the biological traction band to pass out again from the opposite direction of the opposite side;
s4, tightening the biological belt to tighten and fix the superficial transverse muscles of the perineum at the perineum body.
Conventional surgical procedures typically involve dissection of the posterior vaginal wall, muscle separation, and tight suturing of the relaxed bulbar spongium and sphincter vaginae. The injury is large, the recovery is slow, the excision of the mucosa tissue of the back wall part easily leads to the damage of the sensory nerve of the vagina mucosa, the possibility of further aggravating sexual dysfunction is increased, and the rectum is possibly damaged when the back wall is separated and dissected, so that the rectovaginal fistula is caused. The invention utilizes the puncture guiding device to be matched with the biological belt to tighten the muscle of the back wall of the vagina without incision, thereby reducing the injury and simultaneously avoiding the occurrence of guiding rectal fistula.
The vagina mucosa has rich sensory nerve endings, the invention can completely reserve the original vagina mucosa, when the muscle layer is drawn and the suture muscle is contracted, the vagina mucosa is relatively increased, the fold is relatively increased, more friction can be generated during sexual life, the grip strength is correspondingly increased, so that the orgasm of men and women can be easily achieved, and the quality of the sexual life is improved.
By tightening the lower half part of the vaginal opening, the situation of the vaginal opening relaxing can be effectively improved, and a new elastic vaginal opening suitable for the new vaginal opening is formed.
The weakened fascia and the muscle torn at the periphery are found by physical examination, the integrity and tension of muscle tissues are recovered, the muscle contraction force is improved, and the normal perineum body structure is recovered.
The application method of the puncture guiding device of the present invention uses advanced biomaterials, such as decellularized allo dermis. The acellular allogenic dermis has no antigenicity, but keeps a good biological scaffold structure, is convenient for the growth of autologous tissue cells and finally becomes a part of an organism, thereby achieving a lasting effect.
The sensitive point in the vagina is positioned on the front wall of the vagina, and the puncture guiding method does not interfere with the front wall of the vagina in the operation process, thereby effectively preventing the vagina feeling from declining after the operation.
The operation strengthens the support of the pelvic floor, and has certain improvement effect on mild stress urinary incontinence. The original anatomical structure is restored, the distance between the anus and the vagina is increased, the chance of anus pollution to the vagina is reduced, and repeated urinary and reproductive infection is reduced. Improve the internal environment of the vagina and increase the internal lubrication degree of the guide. Effectively improve the symptoms of vaginal dryness, dyspareunia and the like caused by vaginal relaxation.
The following table is clinical data comparing conventional surgical methods to the methods of application of the puncture guide device of the present invention:
finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
