Description

Split type biological suppository for anal fistula treatment

Technical Field

The invention relates to a special medical instrument for anal fistula treatment, in particular to a split type biological suppository for anal fistula treatment.

Background

Anal fistula is a chronic infectious duct with the same perianal skin and rectum/anal canal, is a common sequela of perianal abscess treatment, is a common benign anal disease, and has the second place of hemorrhoids but the second place of the benign anorectal disease. Simple drug therapy is difficult to cure and often requires surgical treatment. The traditional operation modes comprise an anal fistula excising operation, a thread-hanging therapy, an open fistula drainage operation, a transanal rectal mucosa flap internal orifice repairing operation and other operation modes. At present, anal fistula healing and anal function protection are considered to be key indexes for success or failure of treatment, the existing operation treatment modes have problems of anal dysfunction and recurrence, the incidence rate of postoperative anal incontinence is 10% -65%, and the recurrence rate of postoperative anal fistula is 10% -20%. Anal fistula is a common disease that afflicts patients.

In order to solve the above problems, the patent with the publication number of CNCN202892005U discloses a biological plug for anal fistula treatment, which comprises a conical main body, wherein the conical main body is similar to the fistula tract in shape, at least one through hole is arranged on the conical main body, and the axis or the extension line of the axis of the through hole intersects with the perpendicular line of the conical main body. The bottom surface of the biological plug is sutured with the fistula tract inner opening to seal the fistula tract inner opening; cutting off redundant materials at the outer opening of the fistula tract, disinfecting and bandaging the wound, and replacing dressing at the outer opening until the wound is healed. The biological suppository can guide the growth of normal human cells, is gradually consumed by the cells while the cells grow and the tissues are reconstructed, is finally completely degraded, and realizes the reconstruction of autologous tissues. This kind of biological bolt of anal fistula treatment at first need implant when using and sew up, and the operation degree of difficulty of sewing up is big, and secondly this kind of biological bolt wholly is the toper structure, drops easily in the use, consequently provides one kind and does benefit to the quick healing of fistula, reduces anal fistula recurrence rate, improves that patient's travelling comfort resumes providing one kind and does benefit to the special medical instrument of anal fistula treatment in the improvement and has positive economic and social.
