Description
Technical field
This utility model relates to a kind of surgical operating instrument, relates in particular to a kind of instrument for cutting and stitching in surgery, belongs to technical field of medical instruments.
Background technology
People were to the history in surplus the understanding of hemorrhoid existing 4000 year, and the theory of relevant hemorrhoid emerges in an endless stream for a long time.Since 18th century, hemorrhoid are considered to the abundant venous plexus that rectum lower end or anal canal position exist, if at a place or expansion takes place at the number place or varicose promptly becomes hemorrhoid, that is hemorrhoid are the vein groups of giving prominence to, and are the vascular lesions that a variety of causes causes.Since the seventies in 20th century, the research of hemorrhoid has been obtained breakthrough, anatomy, histology and physiological discovery have been given modern notion to hemorrhoid.Thomson proposed first in 1975, and " hemorrhoid are normal anatomical structures that everybody all has, and are lip shape wart or anus pad (anal cushions) in the rectum lower end, and the pathology hypertrophy of anus pad is the hemorrhoid disease." this new notion is subjected to Alexander-Williams (1982), Bernstein (1983) and Melzier famous scholars' such as (1984) support.The external anorectal disease of publishing is recently learned the new ideas that extensively adopted hemorrhoid in the monograph, in the past few years also gains recognition gradually in China anorectal surgical educational circles nearly 10.
The traditional method of internal hemorrhoid treatment comprises that injection of sclerosing agent, rubber snare are pricked and various forms of excision arts etc., all is to treat at hemorrhoid itself, is intended to make blood stasis to dwindle or disappears.In the surgical operation of hemorrhoid excision, a kind of PPH of being called operation method is arranged, i.e. mucosa ring cutting art on the hemorrhoid of carrying out under the help of tubular bookbinding device.Its principle is: organize under the situation at reservation anus pad, with mucosa, the about 3～4cm of submucosa tissue circular resection on internal hemorrhoid and the hemorrhoid, two ends simultaneously coincide, in blocking-up hemorrhoid supply vascular flow, reach slippage organized and upwards suspend fixed purpose in midair, make the anorectal region of pathological state return to normal anatomic status.
Utilization PPH operative treatment severe hemorrhoids, advantages such as having the postoperative pain of alleviating, reduce postoperative hemorrhage, shorten the hospital stays, accelerate recovery period, do not influence daily life, relapse rate is low, the whole surgery process only needs 8～15 minutes, and operation back patient does not almost have the sensation of pain.Because operation has solved the pathogenetic root of hemorrhoid, so it is more satisfactory to reach long-term effect in the recent period.Treat very thorny hemorrhoid for some with traditional remedies, as mixed hemorrhoid, ring-type hemorrhoid, serious prolapse of hemorrhoid, proctoptosis etc., the PPH operation has unique curative effect equally.
Yet clinical practice finds that some patient is not that pathological changes takes place 3 hemorrhoid simultaneously, but wherein 1 or 2 hemorrhoid morbidities at this moment, are used present tubular type binding apparatus excision one circle, and no matter whether all morbidity all can be by disposable complete resection for 3 hemorrhoid.Obviously, this operation will cause unnecessary damage to the patient, and post-operative recovery is not had good effect yet, be unfavorable for the clinical application of this operation method.
