Description
Technical field
The present invention relates to a kind of safeties of disposable anorectal Endo-GIA and drive device, belong to Medical treatment device
Tool, is particularly suitable for use in anal intestine hemorrhoid and cuts identical support the use.
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.
The resist-nailed seat of current disposable anorectal Endo-GIA is directly fixedly connected with regulating bolt, and length is longer, no
It is easy to operative doctor to operate and adjusting screw rod is slower using normal screws governing speed, inconvenient operation, current is disposable
Anal intestine Endo-GIA uses easy hand clamping influence in dual-handle, bar linkage structure, operative doctor operative process to perform the operation just
Often carry out, and dual-handle link transmission discontinuity, easily cause suturing nail and be molded imperfect influence surgical quality.
The content of the invention
The present invention seeks to for above-mentioned weak point provide a kind of safeties of disposable anorectal Endo-GIA with
Drive device, because resist-nailed seat component and adjusting screw rod use split-type structural, mitigates resist-nailed seat weight, is easy to operative doctor to grasp
Make, due to driving anastomosis staple by straight push rod, push jack using flexible handle, anastomosis staple uniform force made in anastomosis procedures,
Shaping is fixed whole, it is ensured that surgical quality, because increase indicates that component can clearly show that operating theater instruments firing position ensures to perform the operation into
Power, reduces patient's pain.Due to using safeties, when less than firing position, it is impossible to fire, it is to avoid mistakenly hit hair ensures hand
Art is normally carried out.It is easy to operate due to using movable monolever, directly holding operation.Regulation adjusting screw rod uses Variable pitch screw, can be with
Accelerate distance between regulation resist-nailed seat component and pin pack assembly, operating time can be shortened, be easy to operation technique.
