Technical field
The utility model relates to a kind of nail supporting base assembly of disposable anorectal Endo-GIA, belong to medical apparatus and instruments, be specially adapted to anorectal hemorrhoid and cut identical supporting the use.
Background technology
Anal and bowel pile is commonly called as hemorrhoid, is the distinctive commonly encountered diseases of the mankind, frequently-occurring disease.Show according to relevant reconnaissance information, the sickness rate of anorectal disease is 59.1%, and hemorrhoid account in all anal and intestinal diseases 87.25%, and wherein common with internal hemorrhoid, account for 52.19% of all anal and intestinal diseases.Men and women all can fall ill, and the sickness rate of women is 67%, and the sickness rate of male is 53.9%, and any age all can fall ill, and increases the weight of gradually along with the increase at age, therefore has saying of " ten people nine hemorrhoid ".General operative treatment comprises the traditional operations such as ligation method, Barron ligation, hemorrhoid excision.Troublesome poeration, requires high to the clinical experience of doctor in operation process, operates careless slightlyly will cause Massive Bleeding, and increase patient painful, extend operating time, success rate of operation is low, and incision out-of-flatness is smooth, and wound suture unsightly.Original disposable anus perianal abscess anastomat front end of using in operation is integrated, inseparable, and front end is again without the pocket hole of adjustable resection organization amount, cutting limitation is large, the space constraining user to operate when practical operation, complex operation step, increases operating time.
The nail supporting base of current disposable anorectal Endo-GIA is directly fixedly connected with adjusting bolt, length is longer, be not easy to operative doctor operation and adjusting screw(rod) adopts normal screws governing speed slower, inconvenient operation, current disposable anorectal Endo-GIA adopts dual-handle, bar linkage structure, in operative doctor operative process, easy hand clamping impact operation is normally carried out, and dual-handle link transmission discontinuity, easily causes that suturing nail molding is imperfect affects surgical quality.
Summary of the invention
This utility model object is the nail supporting base assembly providing a kind of disposable anorectal Endo-GIA for above-mentioned weak point, because nail supporting base assembly and adjusting screw(rod) adopt split-type structural, alleviate nail supporting base weight, be convenient to operative doctor operation, anastomosis staple is driven by straight push rod, push jack owing to adopting flexible handle, anastomosis staple uniform force is made in anastomosis procedures, molding is fixed whole, guarantee surgical quality, can know that display operating theater instruments firing position guarantees success rate of operation owing to increasing indication component, reduce patient painful.Owing to adopting safety, when less than firing position, cannot pull the trigger, avoid mistakenly hit to send out and ensure that operation is normally carried out.Owing to adopting movable monolever, directly hold operation, easy to operate.Regulate adjusting screw(rod) to adopt Variable pitch screw, the spacing regulating nail supporting base assembly and needle chamber assembly can be accelerated, can operating time be shortened, be convenient to operation technique.
The nail supporting base assembly of disposable anorectal Endo-GIA realizes by the following technical solutions:
The nail supporting base assembly of disposable anorectal Endo-GIA comprises nail supporting base, knife washer and connecting axle, nail supporting base front portion has nail supporting base body, nail supporting base body rear portion is provided with nail supporting base knife washer mounting groove, nail supporting base body rear portion is provided with nail supporting base positioning and guiding axle, nail supporting base positioning and guiding axle periphery is provided with gathering sill, positioning and guiding axle bottom is provided with connecting axle installing hole, and knife washer is arranged in nail supporting base knife washer mounting groove.Nail supporting base rear end face is provided with staple forming tank.
Connecting axle rear portion is arranged in the connecting axle installing hole of positioning and guiding axle, and connecting axle rear portion is provided with connecting axle limited step, and connecting axle front portion is provided with connecting axle draw-in groove, and connecting axle leading section is provided with connecting axle guide head.
Operation principle
When the nail supporting base assembly of disposable anorectal Endo-GIA and disposable anorectal Endo-GIA support the use, first counterclockwise turn adjusting nut is by regulating screw mandrel, nail supporting base assembly is released nail bin about 5cm by jump ring pipe, extract nail supporting base assembly, pocket is played to patient with operation, the anorectal that need cut is banded on nail supporting base, take off the over cap of nail bin, pocket nail supporting base will be accomplished fluently again and insert jump ring pipe, turn clockwise adjusting nut, the Clip Reed on jump ring pipe is driven to promote the pointer drive link of indication component, pointer, firing position is indicated by indicating window, drive insurance drive link by drive link erection column simultaneously, open safety, safety block is thrown off from the safety block draw-in groove of the flexible handle cover of flexible handle, manual mode can be adopted to be easy to open safety block if do not thrown off, now doctor can press flexible handle, flexible handle promotes straight push rod, straight push rod promotes pushing slice of nail and the cutter of nail bin groupware, promote staple by tissue apposition simultaneously, after tissue apposition, tissue cuts off by cutter, unclamp flexible handle, straight push rod is driven by flexible handle spring and straight push rod spring, cutter reset, complete anorectal hemorrhoid cutting anastomosis operation.
The nail supporting base component design of disposable anorectal Endo-GIA is reasonable, rational in infrastructure.When the nail supporting base assembly of disposable anorectal Endo-GIA and disposable anorectal Endo-GIA support the use, because nail supporting base assembly and adjusting screw(rod) adopt split-type structural, alleviate nail supporting base weight, be convenient to operative doctor operation, anastomosis staple is driven by straight push rod, push jack owing to adopting flexible handle, anastomosis staple uniform force is made in anastomosis procedures, molding is fixed whole, guarantee surgical quality, can know that display operating theater instruments firing position guarantees success rate of operation owing to increasing indication component, reduce patient painful.Owing to adopting safety, when less than firing position, cannot pull the trigger, avoid mistakenly hit to send out and ensure that operation is normally carried out.Owing to adopting movable monolever, directly hold operation, easy to operate.Regulate adjusting screw(rod) to adopt Variable pitch screw, the spacing regulating nail supporting base assembly and nail bin groupware can be accelerated, can operating time be shortened, be convenient to operation technique.
