Description
Technical field
The present invention relates to scalpel technical field, particularly relate to a kind of anal fistula operating knife.
Background technology
Anorectal fistula mainly invades anal canal, seldom relates to rectum, therefore is commonly referred to as anal fistula, refers to perianal
Granulomatous pipeline, is made up of internal orifice, fistula, collar extension three part.Internal orifice is frequently located in rectum bottom or anal canal, many
It it is one；Collar extension, on anal skin, can be one or more, prolonged more not or intermittent recurrent exerbation, fistula
Held by reactive dense fibrous tissue, be inflammatory granulation tissue at nearly tube chamber, be common anorectal disease
One of.Anal fistula can not spontaneous recovery, not treating can recurrent exerbation perianorectal abscess, it is therefore necessary to operative treatment.
Traditional Treatment of Anal Fistula operation has fistulotomy, ligating method for treating anal fistula and anal fistulectomy, and fistulotomy is by fistula
All cut opening, grow the method cicatrized a wound by granulation tissue, it is adaptable to low level anal fistula, because of fistula outside
Below sphincter deep, only damage Subcutaneous section of external shincter muscle and superficial part after incision, do not have postoperative anal incontinence；
Ligating method for treating anal fistula is to utilize rubber band or have the mechanical pressure effect of medicated line of corrosiveness, slowly cuts the side of anal fistula
Method, the method will not occur the advantages such as skin incision bonding before rubber band comes off；Anal fistulectomy is to cut fistula
And by fistula wall complete resection to health tissues, wound surface is not sewed up, if wound surface is relatively big, can partly sew up, part
Open wide, insert oil gauze, make outward from the bottom the growing to of wound surface heal, it is adaptable to simple low anal fistula.
Traditional Therapeutic Principle is to be cut by fistula, forms the focuses such as the wound surface opened wide, manual rejecting fistula wall
Tissue, then makes wound growth healing.Modus operandi is a lot, operation should according to the height of internal orifice position, fistula with
The relation of anal sphincter selects, operation it is crucial that reduce the damage of anal sphincter as far as possible, prevent anus from losing
Prohibit, avoid the recurrence of anal fistula simultaneously.But traditional anal fistula surgical wound is big, amount of bleeding is big, and patient's is painful big,
Treatment time is long, recovers slow, leaves the biggest edge of a knife, affect attractive in appearance.
Summary of the invention
