Description
Technical field
The utility model relates to the percussion driving devices that a kind of disposable anorectal selects Endo-GIA, for primary
Property anal intestine selection Endo-GIA match, belong to medical instrument, especially suitable for anal intestine hemorrhoid cutting coincide.
Background technology
Anal and bowel pile is commonly called as hemorrhoid, is the distinctive common disease of the mankind, frequently-occurring disease.Show anus according to related reconnaissance information
The incidence of recial disease is 59.1%, and hemorrhoid account for 87.25% in all anorectal diseases, and wherein most commonly seen with internal piles, account for
The 52.19% of all anorectal diseases.Men and women can fall ill, and the incidence of women is 67%, and the incidence of male is 53.9%, any
Age can all fall ill, and gradually be aggravated with the increase at age, therefore it is said that nine out ten suffer from hemorrhoids.General operative treatment includes ligation
The traditional operations such as method, Barron ligation, hemorrhoid excision.It is troublesome in poeration, high, behaviour is required the clinical experience of doctor in the course of surgery
Make it is careless slightly will result in Massive Bleeding, increase patient's pain, extend operating time, success rate of operation is low, and incision is uneven
Whole smooth, wound suture is unsightly.Original disposable anus perianal abscess stapler front end used during surgery is integrated, inseparable
From pocket hole of the front end again without adjustable resection organization amount, cutting limitation is big, and user is constrained to operate in practical operation
Space, it is complex for operation step, increase operating time.
Current disposable anorectal Endo-GIA（PPH）Operation method, that is, stapled propsectomy, when operation, by anal intestine
Whole section of resection and anastomosis of inner tissue together, causes the artery of arteria rectalis superiod supply hemorrhoid to be cut off, postoperative identical tissue blood supply
It reduces, post-operative recovery time is long.
Invention content
The utility model aim is that place provides a kind of hitting for disposable anorectal selection Endo-GIA against the above deficiency
Driving device is sent out, matches for disposable anorectal selection Endo-GIA, in anal intestine hemorrhoid resection operation, selectively cuts
Except prolapsus internal piles, and normal tissue can be retained, hemorrhoid artery is prevented to be completely severed, ensure that postoperative anal intestine tissue blood supply is logical
Freely, post-operative recovery time is short.
Disposable anorectal selects the percussion driving device of Endo-GIA to be realized using following technical scheme：
It includes endless knife, push jack, push jack pushing plate, push jack that disposable anorectal, which selects the percussion driving device of Endo-GIA,

Operation principle
Disposable anorectal selects the percussion driving device of Endo-GIA and disposable anorectal selection Endo-GIA mating
In use, supporting sleeve is sleeved on anus beyond the Great Wall first, supporting sleeve is imported into patient anus, extracts anus plug, then utilizes supporting sleeve
Positioning adjusts the position for needing to perform the operation, then fixes supporting sleeve.It, need to purse wire to needing the tissue cut to play pocket
The tissue to be cut is hung, and turn adjusting nut counterclockwise, by lead screw, pull rod releases resist-nailed seat, and will hang need to cut off group
The purse wire knitted passes through the circular hole among nail bin push jack, tightens purse wire, adjusts the tissue for needing to cut off, rotates clockwise
Adjusting nut is fixed the tissue for needing excision, and by showing that window pointer enters green area, doctor can press activity at this time
Handle, flexible handle push straight push rod, and straight push rod is by pushing push jack that panel seat, push jack pushing plate is pushed to push push jack and annular
Knife, while anastomosis staple being pushed to suture tissue, after tissue suture, what closed ring knife was not selective will need the tissue cut off to cut
It is disconnected, flexible handle is unclamped, drives straight push rod, endless knife to reset by flexible handle spring, rotating adjusting nut counterclockwise, ejection
Resist-nailed seat unclamps tissue, and extraction disposable anorectal selects Endo-GIA, completes anal intestine hemorrhoid selection cutting anastomosis operation.
Disposable anorectal selects the percussion drive assembly design of Endo-GIA reasonable, reasonable for structure, disposable anorectal choosing
The percussion driving device and disposable anorectal selection Endo-GIA for selecting Endo-GIA match conveniently.Using not closed
Arcuate cutting blade, nail bin, push jack, according to hemorrhoid distribution situation, selectively cutting coincide, and reduces wound.Its mechanism is to have followed
The Forming Mechanism of human body hemorrhoid is formed according to the physiological and pathological structure design of hemorrhoid.It is sticked in the hemorrhoid of precise ablation prolapsed portion when treatment
Film, the pathologic, physiologic for not only having corrected for hemorrhoid sexually revise, but also remain normal anus pad and mucosal bridge, maintain the normal work(of anus
Can, reduce operation wound, post-operative recovery time also greatly shortens.Doctor is easy to operate at the time of surgery, when the finger of observation window
Show needle in green area, the at this moment percussion of flexible handle front end is insured boss and is located at below the escape groove of pointer drag hook front end, presses
When dynamic flexible handle, the percussion insurance boss of flexible handle front end can pass through the escape groove of pointer drag hook front end, complete percussion,
Without as existing product, after doctor will also open insurance, can just fire.In the course of surgery, indicator does not exist
Green area, if doctor has accidentally pressed flexible handle, at this point, the percussion insurance boss directly top of flexible handle front end is arrived
It in pointer drag hook main body, cannot fire, mistakenly hit hair is avoided to ensure that operation is normally carried out, instruction safety device greatly reduces operation
Present in risk.Lead screw uses gaining twist, can accelerate to adjust the distance between resist-nailed seat and nail bin, when shortening operation
Between, reduce the pain that operation is brought to patient.
