Description
Technical field
The utility model relates to a kind of nail bin transmission mechanisms of disposable arc line shaped Endo-GIA, belong to doctor
Instrument is treated, is matched with disposable arc line shaped Endo-GIA, especially suitable for anal intestine hemorrhoid cutting operation, rectal polyp
Resection.
Background technique
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 disease 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 disease incidence of women is 67%, and the disease incidence of male is 53.9%, any
Age can all fall ill, and gradually aggravate with the increase at age, therefore it is said that nine out ten suffer from hemorrhoids.
Endo-GIA is the equipment of the substitution traditional-handwork cutting suture medically used.Arc-shaped cutting anastomat conduct
A kind of disposable Endo-GIA has a variety of designs using advantage, such as its front end arc convenient for going deep into anal intestine
The small space in deep, cutting and suture synchronously complete, and simplify surgical operation step.Arc-shaped cutting anastomat when in use,
So that it is convenient to which the adjusting to tissue positions by the way of segmented closure, and position and lock is carried out with pilot pin, then again
It is cut and is sutured.Conventional arched Endo-GIA controls pilot pin using pushing before and after navigation button, is controlling in this way
On there are unstable factors, be easy to cause tissue to be subjected to displacement, need constantly to relocate, increase operation duration, sternly
The position inaccuracy for also resulting in cutting suture of weight, generates more serious consequence.In addition, traditional arc-shaped cutting anastomat without
Method replaces component, and same operation may use more instrument, causes to perform the operation at high cost, brings bigger economy to bear to patient
Load.

Working principle
The nail bin transmission mechanism of disposable arc line shaped Endo-GIA, with disposable arc line shaped Endo-GIA
Match, disposable arc line type Endo-GIA when in use, first by assembled replaceable resist-nailed seat component, can
Nail bin groupware and replaceable push jack knife assembly are replaced, assembled fixed handle, resist-nailed seat revolving joint, work are packed into
Fixed handle, left support, right support, nail bin transmission mechanism, push jack cutter transmission mechanism, resetting-mechanism, in indicating mechanism, then into
Row operation, selects the hemorrhoidal tissue that need to be cut off or rectal polyp, presses flexible handle, and the right sliding block protrusion of flexible handle is sliding at this time
Move right sliding block flexible handle sliding gear card slot in, while flexible handle extension bar push boss push extension bar, extension bar set,
Left support plate, right support plate, rotation fixed block, closure push rod, nail bin connection panel seat, upper nail bin connecting plate, lower nail bin connecting plate,
Staple cartridge tray, nail bin, further the distance between nail bin and resist-nailed seat, checks whether cutting position is suitable by resetting-mechanism, if not
Properly, reset button is pressed, the button lower end that makes to give up the throne is applied to the giving up the throne on button boss of right sliding block, in the effect of sliding block spring
Under, so that the right sliding block protrusion on the right side of flexible handle is detached from the flexible handle sliding gear card slot of right sliding block, in nail pushing plate tension spring
Under effect, reset nail bin.If suitable by resetting-mechanism inspection cutting position, continue to press flexible handle, until extension bar,
Extension bar set is in straight line, reaches self-locking state, it has been to cut that flexible handle resets under the action of flexible handle spring at this time
Slot is combined to knit and be ready, if malposition, equally presses reset button, the extension bar button projection for button lower end of giving up the throne,
It acts on extension bar, under the action of nail pushing plate tension spring, retracts nail bin, play the role of reset.Pass through the instruction of resetting-mechanism
If needle indicates that cutting position is suitable, flexible handle is pressed again, the left slider protrusion on the left of flexible handle is made to slide into left slider
Flexible handle sliding gear card slot in, under the action of fire spring, be fire push plate act against trigger shaft back seat upwards
It fires push plate to push on groove, while pressing flexible handle, the trigger shaft back seat of percussion push plate front end pushes boss to push
Trigger shaft back seat, trigger shaft, push jack connect panel seat, push jack connecting plate, push jack, cutter, complete cutting coincide, press reset by
The extension bar button projection of button, the button lower end that makes to give up the throne acts on extension bar, and panel seat spring is connected with push jack in nail pushing plate tension spring
Under effect, reset push jack cutter, nail bin resets, and under the action of flexible handle spring, resets flexible handle, completes hand
Art.If operation be not finished, patient needs to cut many places haemorrhoids or rectal polyp, then after taking out instrument, press down unload component by
Button deviates from the protrusion for unloading component button out of fixed link, rotates assembled replaceable resist-nailed seat component, replaceable nail bin group
Part and replaceable push jack knife assembly, it is removed, and is packed into new assembled replaceable resist-nailed seat component, replaceable nail bin

Height, the design of step surface nail bin are enable tissue to restore blood supply faster, are accelerated postoperative patient wound using the high suture of different nails
Healing, due to be provided with replaceable resist-nailed seat, nail bin, knife assembly, the design of replaceable assembly, reduce operation at
This, mitigates patient economy burden.Three gear closed designs, can preferably adjust cutting anastomotic site during surgery, reduce and cut
Except the risk of normal tissue, it in addition can be used with disposable anorectal selection cutting peeker and headlamp, preferably complete rectum
The local excision of polyp.
Rationally, compact-sized, stable transmission, moment is big for the design of nail bin transmission mechanism, and intensity is high, and selection needs to cut off in operation
Hemorrhoidal tissue or rectal polyp, press flexible handle, the right sliding block protrusion of flexible handle slides into the activity of right sliding block at this time
Handle slides in gear card slot, while the extension bar of flexible handle pushes boss to push extension bar, extension bar set, left support plate, right support
Plate, rotation fixed block, closure push rod, nail bin connect panel seat, upper nail bin connecting plate, lower nail bin connecting plate, staple cartridge tray, nail bin, draw
Nearly the distance between nail bin and resist-nailed seat；If suitable by resetting-mechanism inspection cutting position, continue to press flexible handle, directly
It is in straight line to extension bar, extension bar set, reaches self-locking state, flexible handle resets under the action of flexible handle spring, at this time
It has been that disposable cutting suture tissue of completing is ready.
The nail bin transmission mechanism of disposable arc line shaped Endo-GIA, with disposable arc line shaped Endo-GIA
It matches, disposable arc line shaped Endo-GIA is suitable for anal intestine polyp cutting operation, rectal polyp cutting operation, anus
Perianal abscess core local excision operation, replaceable resist-nailed seat, nail bin, knife assembly can 360 degree rotation, can arbitrarily adjust during surgery
Surgery location reduces operating difficulty.Three nails are set in nail bin, and step nail is high, after completion cutting coincide, it is easier to keep tissue extensive
Multiple blood supply, accelerates the wound healing of postoperative patients.Due to being provided with replaceable resist-nailed seat, nail bin, knife assembly, drop
Low operation cost, alleviates the financial burden of patient.
