The doctor is when doing the digestive tract end to end anastomosis, often use tube type anastomat to operate, before coincideing, just must at one end carry out the ailhead that purse string suture is implanted tube type anastomat to tissue, at present a lot of doctors are manual suture pockets, but can't guarantee whether organizing of pocket be suitable, if residual tissue too much can cause anastomat to excite failure; As very few, the risk of fistula is arranged after then coincideing.Therefore in use, the use pocket anastomat that the doctor is more and more many is made pocket.And the seam of pocket anastomat in the market nail all is the part levels that only penetrate intestinal tube, does not tightly come off owing to purse wire is fixing when tightening up pocket like this, causes failure when coincideing.
The patent that the applicant declares before this " a kind of pocket pincers anastomat ", disclosed a kind of pocket wrench structure, its main characteristic is the nail supporting base that has adopted a kind of metal material, compare with the plastics nail supporting base that uses in the past, this metal nail supporting base is safer, firm, when purse wire tightens up, the titanium nail is not drawn out, simultaneously, make each layer tissue be thrown into pocket effectively, help the healing of wound.But on probation, feel that this structure also has weak point, in order further to increase work efficiency, and for different human bodies part identical had adaptability widely, the applicant makes improvement to the structure of pocket pincers once more, is intended to increase state the work efficiency that the back is sewed up.
Summary of the invention
This utility model technical issues that need to address are, trying out the work efficiency that occurs in the process at the applicant at " a kind of pocket pincers anastomat " of first to file has much room for improvement, and under the demand that the scope of application remains to be widened, examine and improve the shape and structure of pocket pincers anastomat again closely.
The purpose of this utility model provides a kind of pair of nail supporting base pocket pincers anastomat structure, for realizing the purpose of this utility model, the technical scheme that is adopted is as follows, a kind of pair of nail supporting base pocket pincers anastomat, comprise and be positioned at forward nail cartridge component and nail supporting base assembly, be positioned at the last lower plier handle at middle part, it is characterized in that, the front portion is provided with, following two nail cartridge components, be separately fixed at be positioned at the middle part on, on the lower plier handle, a horizontal T shape nail supporting base assembly places between two nail cartridge components, constitutes two nail supporting base structures, horizontal T shape connects and has a circular hole on the handle, inserts fixing mutually with the pin on the last lower plier handle.The T-shaped bonding jumper of described anterior nail supporting base is horizontally placed between two nail cartridge components and with two and follows closely cartridge component interlocks mutually, and this metal material is chosen for rustless steel.
The beneficial effects of the utility model are, adopt the nail supporting base of stainless steel, because nail supporting base is durable indeformable, make the titanium in the nail cartridge component follow closely the effectively saturating corresponding tissue of ground nail, and when purse wire tightened up, the titanium nail was not drawn out, simultaneously owing to will organize nail saturating, make each layer tissue effectively be thrown into pocket, help being organized in the effectively healing of back that coincide.Compared with the structure of single nail supporting base, the efficient of this structure is able to further raising.
