Embodiment Construction

[0023] In order to better understand the technical solution of the present invention, the present invention will be further described below through specific examples.

[0024] refer to Figure 1 to Figure 7 As shown, a split-type biological embolus for anal fistula treatment includes a plug 1, a lead wire 2, a peg post 3 and a fixing device 4;

[0025] The plug 1 is made of soft materials such as silica gel, and one end of the plug is in the shape of a mushroom with a curved surface, the diameter of which is larger than that of the plug post 2 and is also obviously larger than that of the internal opening 100 of the anal fistula, and the edge of the end face has a smooth transition 11;

[0026] The lead wire 2 is made of degradable absorbing material. The lead wire 2 is long and thin, and its length is 8-16cm. The lead wire 2 is composed of a connected soluble section 21 and a free section 22. The diameter of the lead wire 2 is 0.5mm-1.0mm , the length of the soluble section ...

Abstract

The invention relates to a special medical instrument for anal fistula treatment, in particular to a split type biological suppository for anal fistula treatment. The split type biological suppositoryfor the anal fistula treatment comprises a plug, a suppository column and a lead, the diameter of the plug is larger than that of the suppository column, a channel is formed in the suppository column, the lead comprises a soluble section connected with the plug and a free section capable of penetrating into the suppository column, and the penetrating part of the free section of the lead is fixedinto the channel when penetrating into the channel of the suppository column. And the soluble section is arranged in a gap between the plug and the end part of the suppository column. According to thesplit type biological suppository for the anal fistula treatment, the plug and the suppository column are designed in a split mode, the plug does not need to be sewn in the using process and directlycovers an inner opening of a fistula opening, the plug and the suppository column can be automatically discharged out of the anus along with defecation after the lead is decomposed, and the suppository column can automatically fall off in the follow-up process; the split type biological suppository for the anal fistula treatment is simple in structure and convenient to operate, suture steps are reduced, damage to perianal tissue is small through detection, and the using effect is good.

Description

technical field [0001] The invention relates to a special medical device for treating anal fistula, in particular to a split-type biological embolus for treating anal fistula. Background technique [0002] Anal fistula is a kind of chronic infectious duct with the same perianal skin and rectum / anal canal. It is a common sequela of perianal abscess treatment and a common anal benign disease. two. Drug therapy alone is difficult to cure and often requires surgical treatment. Traditional surgical methods include anal fistula resection, seton therapy, fistula drainage, and anorectal mucosal flap repair. At present, it is believed that both the healing of anal fistula and the protection of anal function should be used as the key indicators of the success or failure of the treatment. The existing surgical treatment methods all have problems of anal dysfunction and recurrence, and the incidence of postoperative anal incontinence is between 10% and 65%. The postoperative recurren...
