Biotype mini-urethral canal hanging strip

Abstract

The invention discloses a biotype mini urethral tape, which is made of biomembranes which are treated by special technology. The urethral tape is a membrane tape, wherein the middle of the membrane tape is long and narrow, and both ends of the membrane tape are gradually widened and diverged into symmetrical double-fork structures; divergent fixing tapes on both ends are mainly used for suturing and fixing; a middle bearing tape is mainly used for bearing the urethra; the overall urethral tape is short and refine; the total length of the overall urethral tape is between 40 and 80 millimeters and is preferably 10 millimeters; the maximum extending width of both ends is between 15 and 40 millimeters and is preferably 20 millimeters; and the width of the middle bearing tape is between 10 and 20 millimeters and is preferably 10 millimeters. The biotype mini urethral tape does not need to go deep into an organism for suture, is easy for surgical operation, is made of the materials which are treated by the special technology, has high stability and good biocompatibility, is difficult to degrade and cause exclusive reaction, can guide nerve structures of patients to extend into the biotype mini urethral tape, and finally realizes bearing and suspending of the nerve structures of the patients.

Description

technical field [0001] The invention relates to the field of implanted medical devices, in particular to a biological miniature urethral sling. Background technique [0002] Women's stress urinary incontinence is a common disease in middle-aged and elderly women. According to statistics, the incidence rate of this disease in women over 50 years old is more than 30%. Suspension improves the loose sagging urethra. Therefore, in order to cooperate with the application of suspension, various urethral straps have been developed. As far as the materials of the straps are concerned, they are almost all synthetic material woven nets, such as polypropylene woven nets; Longer woven mesh (above 100mm) penetrates deeper and even penetrates into the abdominal muscles for fixation. Due to the poor histocompatibility of synthetic materials, discomfort caused by foreign body stimulation often occurs, and even erosion occurs, penetrating into the vagina and affecting sexual life; if the sl...

AI Technical Summary

Problems solved by technology

Due to the poor histocompatibility of synthetic materials, discomfort caused by foreign body stimulation often occurs, and even erosion occurs, penetrating into the vagina and affecting sexual life; if the sling is too long and pierced too deeply, it is easy to puncture other tissues, and the operation is difficult. Some doctors with less qualifications are afraid to do this kind of operation
