Description
Technical field
This utility model relates to a kind of binder mechanism, and particularly a kind of binder mechanism that is used for anus hemorrhoid Binding Instrument belongs to medical instruments field.
Background technology
People were to the history in surplus the understanding of hemorrhoid existing 4000 year, and for a long time, the theory of relevant hemorrhoid emerges in an endless stream.Since 18th century, hemorrhoid are considered to rectum lower end or anal canal and have abundant venous plexus, if at a place or the number place expansion or varicose take place, promptly become hemorrhoid, that is hemorrhoid are the vein groups of giving prominence to, be the vascular lesion 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 give hemorrhoid and have given modern notion.Thomson proposed first in 1975, and " hemorrhoid are normal anatomical structures that everybody all has, and at the lip shape wart or the title anus pad (anal cushions) of rectum lower end, the pathology hypertrophy of anus pad is the hemorrhoid disease." this new notion in the past few years also gains recognition gradually in China anorectal surgical educational circles nearly 10.The traditional method of internal hemorrhoid treatment, all be to treat at hemorrhoid itself comprise that injection of sclerosing agent, rubber snare are pricked and various forms of excision arts etc., be intended to make blood stasis to dwindle or disappear, but effect is not fine, the post-operative recovery time is long, complication, sequela incidence rate height.In the surgical operation of the hemorrhoid excision of rising in recent years, a kind of PPH of being called operation method is arranged, i.e. mucosa ring cutting art on the hemorrhoid under the help of tubular anastomat.Its principle is: organize under the situation at reservation anus pad, with mucosa, the about 3-4cm of submucosa tissue circular resection on part internal hemorrhoid and the hemorrhoid, two ends simultaneously coincide, in blocking-up hemorrhoid supply vascular flow, the tissue that reaches slippage upwards suspends fixed purpose in midair, with the anorectal region of pathological state, return to normal anatomic status.Advantages such as utilization PPH art treatment severe hemorrhoid disease has the postoperative pain of alleviating, reduces postoperative hemorrhage, shortens the hospital stays, accelerates recovery period, do not influence daily life, relapse rate is low.The whole surgery process only needs 8-15 minute, and operation back patient does not almost have the sensation of pain.Owing to solved the pathogenetic root of hemorrhoid in the operation process, so reach the long-term effect ideal in the recent period.With the very thorny hemorrhoid of traditional remedies, as mixed hemorrhoid, ring-type hemorrhoid, serious prolapse of hemorrhoid, proctoptosis etc., the PPH operation has unique good efficacy equally to some.But, the technical ability of this operation is only grasped in some veteran surgeon's handss now, and the reason that influences its popularization is a lot, and some reason is because existing apparatus exists some defectives, make operation complicated loaded down with trivial details, so the doctor who lacks experience is difficult for grasping.Traditional apparatus is as the space that holds hemorrhoid with the nail tube, this spatial size is decided by the diameter of nail tube, the diameter volume of spike tube more is big more, if the pathological changes of hemorrhoid is more serious, volume is just very big, and that just needs to select large diameter Binding Instrument hemorrhoid all could be held and excised fully, just can undergo surgery greatlyyer but large diameter Binding Instrument must make anal canal strut, and this causes that just a lot of postoperatives have an intense pain even the immediate cause of anal fissure, is unfavorable for the enforcement and the popularization of performing the operation.
Summary of the invention
