Description
Technical field
The present invention relates to the percussion drive device that a kind of disposable anorectal selects Endo-GIA, for disposable anus
Intestines selection Endo-GIA is supported the use, and belongs to medicine equipment, is particularly suitable for use in the cutting of anal intestine hemorrhoid and is coincide.
Background technology
Anal and bowel pile is commonly called as hemorrhoid, is the distinctive common disease of the mankind, frequently-occurring disease.Show according to relevant reconnaissance information, anus
The incidence of disease of recial disease is 59.1%, hemorrhoid account in all anorectal diseases 87.25%, it is 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 disease of women is 67%, and the incidence of disease 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.Troublesome poeration, requires high, behaviour in surgical procedure to the clinical experience of doctor
Make it is careless slightly will result in Massive Bleeding, increase patient's pain extends operating time, success rate of operation is low, incision is uneven
Whole smooth, wound suture is unsightly.Original disposable anus perianal abscess stapler front end used in operation is integrated, inseparable
From again the pocket hole that front end is measured without adjustable resection organization, cutting limitation is big, constrains what user operated in practical operation
Space, complex operation step increases operating time.
Current disposable anorectal Endo-GIA（PPH）Operation method is stapled propsectomy, during operation, by anal intestine
Whole section of resection and anastomosis of inner tissue together, causes the artery that arteria rectalis superiod supplies hemorrhoid to be cut off, postoperative identical tissue blood supply
Reduce, post-operative recovery time is long.
The content of the invention
The present invention seeks to provide the percussion drive that a kind of disposable anorectal selects Endo-GIA for above-mentioned weak point
Dynamic device, is supported the use, in anal intestine hemorrhoid resection operation, selectively excision is de- for disposable anorectal selection Endo-GIA
Vertical internal piles, it is possible to retain normal tissue, prevent hemorrhoid artery to be completely severed, it is ensured that postoperative anal intestine tissue blood supply is unobstructed, art
Recovery time is short afterwards.
The percussion drive device of disposable anorectal selection Endo-GIA is realized using following technical scheme：
The percussion drive device of disposable anorectal selection Endo-GIA includes endless knife, push jack, push jack pushing plate, push jack and promoted

Operation principle
The percussion drive device of disposable anorectal selection Endo-GIA is supported the use with disposable anorectal selection Endo-GIA
When, support set is enclosed on anus beyond the Great Wall first, support set is imported into patient's anus, anus plug is extracted, then using the positioning of support set,
Regulation needs the position performed the operation, and then fixes support set.Pocket is played to the tissue for needing to cut, cutting will be needed with purse wire
Tissue hang, turn adjusting nut counterclockwise, by screw mandrel, pull bar releases resist-nailed seat, and the lotus of resection organization is needed by hanging
Envelope curve, the circular hole through in the middle of nail bin push jack, tightens up purse wire, adjusts the tissue for needing to cut off, turn clockwise regulation spiral shell
Mother, being fixed needs the tissue of excision, and by showing that window pointer enters green area, now doctor can press flexible handle,
Flexible handle promotes straight push rod, and straight push rod is by promoting push jack to promote panel seat, push jack pushing plate to promote push jack and endless knife, together
When promote anastomosis staple by tissue apposition, after tissue apposition, the tissue cut-out that will need to cut off of closed ring knife selectivity, pine
Flexible handle is opened, drives straight push rod, endless knife to reset by flexible handle spring, nail is supported in rotate counterclockwise adjusting nut, ejection
Seat, unclamps tissue, extracts disposable anorectal selection Endo-GIA out, completes anal intestine hemorrhoid selection cutting anastomosis operation.
The percussion drive assembly design of disposable anorectal selection Endo-GIA is rationally, rational in infrastructure, disposable anorectal choosing
The percussion drive device and disposable anorectal selection Endo-GIA for selecting Endo-GIA are supported the use conveniently.Using what is do 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, the physiological and pathological structure design according to hemorrhoid is formed.Sticked during treatment in the hemorrhoid of precise ablation prolapsed portion
Film, the pathologic, physiologic that both correct for hemorrhoid is sexually revised, and normal anus pad and mucosal bridge are remained again, maintains the normal work(of anus
Can, operation wound is reduced, post-operative recovery time is also greatly shortened.Doctor is easy to operate in operation, when the finger of observation window
Show pin 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
During 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, doctor will be also opened after insurance, can just be fired.In surgical procedure, indicator does not exist
Green area, if doctor's imprudence has pressed flexible handle, now, the percussion insurance boss directly top of flexible handle front end is arrived
In pointer drag hook main body, it is impossible to fire, it is to avoid mistakenly hit hair ensures that operation is normally carried out, indicate that safeties greatly reduce operation
Present in risk.Screw mandrel uses gaining twist, can accelerate the distance between regulation resist-nailed seat and nail bin, when shortening operation
Between, reduce the pain that operation is brought to patient.
