This technical scheme can effectively reduce the surface of a wound, and then reaches the problem that reduces patient's operation misery and shorten recovery time, and postoperative perianal scar is little, reaches the purpose of the fistula of wicresoft's treatment to and reduce anal sphincter damage, reduce the anal incontinence risk.
Description
Technical Field
The utility model relates to the field of surgical instruments, in particular to a fistula tract stitching instrument.
Background
Anal fistula, also known as anal canal rectal fistula, is a granulation swelling canal in which the anal canal or rectum communicates with the perianal skin, mainly invades the anal canal and rarely involves the rectum, so the anal fistula is usually called anal fistula, with the inner opening located near the dentate line and the outer opening located at the perianal skin. The whole fistula wall is composed of thickened fibrous tissues, and a layer of granulation tissues is covered in the fistula wall, so that the fistula wall is not healed for a long time.
The treatment method mainly comprises the following steps:
the fistulous tract incision is suitable for simple low-position anal fistula, and during operation, the fistula is completely cleared with the probe, and the fistula is completely incised along with the probe to scrape granulation tissue in the fistula, so that the wound is V-shaped. Filling oil gauze in the wound surface, and after 2-3 days, using 1: 5000 potassium permanganate or hot water for hip bath, and can clean wound surface. After 2-3 days of operation, the wound healing is accelerated by changing the dressing locally with a tissue regeneration promoting ointment or a growth hormone preparation; however, the wound surface is large and open, the patient suffers great pain, and the recovery period is long.
The method can avoid postoperative anal incontinence caused by one-time incision, rupture and contraction of sphincter, and has wide clinical application and simple and convenient operation. The defect is that the postoperative recurrence rate is high, and the high complex anal fistula can be changed into simple anal fistula by hanging the line for many times. The operation method is that under anesthesia, a probe is firstly inserted from an external orifice, penetrates out along a fistula through an internal orifice, a rubber band is tied on the probe at the internal orifice, then the rubber band is led out from the internal orifice through the fistula at the external orifice, the skin between the internal orifice and the external orifice is incised, and the rubber band is tightened to be ligated. The thread can be tightened again after 3-5 days of operation, the rubber band falls off within 1-2 weeks after operation, the left open wound surface can be gradually healed, if the rubber band does not fall off after two weeks, the tissue tied by the rubber band can be cut off by scissors or the thread can be tightened again.
