Description
The present invention is: application number is 200810174395.1, and the applying date is 2008.11.4, and name is called dividing an application of " a kind of assistive device that is used for anal-surgery ".
Technical field
The present invention relates to the assistive device of a kind of anorectal section operation, especially, belong to medical instruments field for a kind of novel assistive device that is used for operations such as rectal polyp, encysted rectum.
Background technology
Anal and rectal diseases mainly refers to the various diseases of anus, rectum, colon, and common anorectal disease has internal hemorrhoid, external hemorrhoid, anal fissure, anal fistula, anal orifice and rectal intestine prolapsus, rectal polyp, encysted rectum etc.; Colon disease has ulcerative colitis, polyp of colon, diverticulitis of colon, colon tumor etc.
The anus dilator seat of prior art is the assistive device a kind of commonly used of anorectal section, and it plays an important role in the check of anorectal section, operative treatment process.The anus dilator seat that comparatively generally adopts is a straight-tube shape structure that has the edge at present, and its edge is controlled by the doctor or the skin closure at direct and anus edge is fixed.The effect of anus dilator seat is to strut anus, for follow-up inspection or treatment are prepared.But its function of the apparatus of this structure is very single, and for the ease of the use of operation, it also needs to cooperate a piped subsidiary conduit with tapered distal end of circle.Particularly in the hemorrhoids surgical of other than ring type cutting, such situation makes the step of operation various, is unfavorable for the quick enforcement of performing the operation, and has also increased patient's misery indirectly.
Rectal polyp general reference mucous membrane of rectum surface in the anal and rectal diseases includes adenoma, child form polyp, inflammation polyp and polyposis etc. to the outstanding protrusion lesion of enteric cavity.From pathology, its content differs, and has plenty of benign tumor, has plenty of the outgrowth consequence of inflammation.But because naked eyes be it seems broadly similar, so the general unclear name of disease " polyp " of this connotation is adopted by custom always.Rectum is the common place of polyp, more owing to be easy to find and handle, thereby paid attention to by the people.Think that in recent years knot, rectal cancer rise from polyp, excise the generation that polyp can reduce cancer early, so polyp comes into one's own more as precancerous lesion.
Encysted rectum, promptly rectum front wall is outstanding, also claims rectum preceding bulging, is that one of syndrome is blocked in outlet.The weak rectal wall of patient's recto-vaginal septum is charged into intravaginal, also is one of principal element of difficult defecation.Rectum front wall is supported by recto-vaginal septum, should be every mainly forming by fascia intrapelvina, in the center line decussating fibers tissue and the perineal body of levator ani m. are arranged.If recto-vaginal septum is lax, then easily bulging forward of rectum front wall, similar hernia is outstanding.Being more common in chronic constipation causes the bad person of women, grand multipara, bowl evacuation habit, the inspection of old women perineum that intra-abdominal pressure increases for a long time and relaxes etc.
Modus operandi for above-mentioned two kinds of diseases mainly contains following 3 classes at present:
One, repair in the per rectum, concrete operation method divides 2 kinds:
(1) in the rectum lower end, 0.5cm place, tooth trace top makes longitudinal incision, is about 7cm, reaches tela submucosa deeply, appears the flesh layer, and according to the width of prolapse, free both sides mucosal flap is 1～2cm.Left side forefinger inserts intravaginal, with posterior vaginal wall to rectum direction jack-up, so that assist hemostasis by compression and prevent to damage vagina, sew up with 2/0 chromicized catgut then, the distance of opening in the entry point distance can be decided according to the prolapse degree, general entry point be chosen in the normal structure place, edge of prolapse can be from levator ani m. edge, right side from inserting needle outside to inside, finish from levator ani m. edge, left side again, can touch out a vertical and firm muscle column with right hand forefinger.Needle point is sure not to pass the posterior vaginal wall mucosa during stitching, in case vaginorecta fistula takes place.Revise two side form lobes at last, with chromicized catgut interrupted suture mucosa otch.The built-in vaseline gauze of rectum is drawn from anus.
(2) make transverse incision at the tooth trace place, length is 1.5～2cm, and upwards each work is vertical at the otch two ends makes otch, and every side is about 7cm, becomes the U font.The muscular layer of mucosa lobe of broad (in the lobe flesh layer must be arranged) at the bottom of the free radical, muscular layer of mucosa lobe upwards separate the weakness that must surpass recto-vaginal septum.Do 3～4 interruptions earlier and walk crosswise stitching, walk crosswise the folded lax recto-vaginal septum of seam; Make 2～3 pins again and be interrupted vertical the stitching, shorten straight Yao antetheca, reduce the tension force of sewing up the muscular layer of mucosa lobe, promote healing.Excise too much mucosa,, be interrupted at last or sew up the both sides longitudinal incision continuously muscular layer of mucosa lobe edge and tooth trace interrupted suture.
Two, per rectum enclosed patching: according to the prolapse size, with curved hemostatic forceps stringer clamp mucous membrane of rectum layer, reuse 2/0 chromicized catgut is sewed up muscular layer of mucosa from bottom to top continuously, up to the pubic symphysis place.Should descend during stitching wide down narrow, in order to avoid form mucosal flap influence defecation in the upper end.This method is only applicable to less (1～2cm) encysted rectum.The per rectum approach is repaired the advantage of encysted rectum: 1. method is easy; Can treat the anorectal disease that other are followed simultaneously; 2. available local anaesthesia is finished the hands art; 3. more directly can fold puborectalis forward, rebuild ano-rectal angle near distinguishing on the sphincter.This method shortcoming is not to be both to correct the outstanding or enterocele of bladder, and the person also is not that per anum is repaired the stenosis of anal canal, merges above situation person and is advisable with the vagina repairing.
Three, the legal repairing encysted rectum of internal rectum closing seam: its operation main points are in the dual continuous interlocking stitching of encysted rectum place row, should locate mucous membrane of rectum, submucous tissue and flesh layered suture and unify, elimination rectum front wall capsule bag.Continuously interlocking is sewed up and will be tied tight, reaching the strangulation effect, thereby causes that mucosal necrosis comes off, and descends and muscle layer tissue makes the wound surface quickly-healing by this place mucosa.Such operation is applicable to the interposition encysted rectum, characteristics be quick, simple, go out insufficiency of blood, weak point be prolapse sealing sometimes not exclusively, postoperative can recur.
The shortcoming of above several method is exactly: operation process is complicated, and all is manual suture, and stitching speed is slow, and sewing effect is undesirable.
