Foreskin Endo-GIATechnical field
The present invention relates to medical instruments field, more particularly to a kind of foreskin Endo-GIA.
Background technology
Male's redundant prepuce or phimosis are common diseases in male reproductive system.Foreskin is covered in whole glans penises and urethraCollar extension, and form semi-open chamber with coronary sulcus.The bacterium of scurf, foreskin secretion and growth is formed in this chamberLong smegma.Due to redundant prepuce or phimosis so that smegma is gathered for a long time, form foreskin and explain, concurrent posthitis will drawSend out the various disease conditions such as paraphimosis tion of paraphimosis, urinary tract infection.Current redundant prepuce or phimosis are mainly treated by circumcision.Long foreskin is cut off using foreskin Endo-GIA and simultaneously with the identical wound of anastomosis staple, is greatly reduced operating time, is mitigated diseasePeople's pain.Otch is neat simultaneously, and healed surface is smooth after recovery.Peritomize except above-mentioned illness can be eliminated, moreover it is possible to effectively pre-The generation of anti-carcinoma of penis and AIDS.
In the prior art（WO2015/010477A1）A kind of disposable foreskin Endo-GIA is disclosed, including tortoiseHead-shield, needle chamber, endless knife, screw rod and flexible handle, wherein glans penis cover rear portion are provided with short tube, and short tube is nibbled with screw rod by screw threadClose.In use, glans penis cover is removed from stapler main body first, foreskin is then encased into glans penis cover and consolidated with bindingIt is fixed, foreskin is fixed on glans penis cover outer surface.Next, the short tube after glans penis cover is engaged with screw rod, and adjusted by screw rodCutting position.Finally, flexible handle is excited, unnecessary prepuce tissues are cut off using endless knife, while anastomosis staple is by foreskin otchPlace coincide.Another prior art（CN103815949A）A kind of disposable prepuce anastomat is disclosed, including glans penisSeat, nail bin ring, blade, adjusting knob and handle, wherein glans penis seat are provided with pull bar.In use, first by glans penis seatRemoved from stapler main body, foreskin is then encased into glans penis seat and fixed.The position of glans penis seat is determined by adjusting knob.Finally, flexible handle is excited, unnecessary prepuce tissues are cut off using blade, while foreskin incision is coincide by anastomosis staple.
It is above-mentioned in the prior art, glans penis cover, which has, diametrically protrudes from glans penis cover surface, ring for installing nail anvilShape structure.This annular causes the size of glans penis cover to be much larger than glans penis size.Therefore, cause foreskin first during fixed foreskinFirst to cross above-mentioned loop configuration can just be fixed on glans penis cover.It is generally narrow along with foreskin opening yet with phimosis,I.e. foreskin front opening is less than glans penis diameter, although foreskin has certain elasticity, but is difficult still that size is straight much larger than glans penisThe glans penis cover in footpath stretches into ostium praeputiale.Therefore peritomize preoperative, will must be cut in advance at foreskin opening along penis direction in progressGo out a gap, glans penis cover is smoothly stretched into expand ostium praeputiale, hereafter open seam is merged again and is bound in glans penis cover rearScrew rod on.Especially for children, the foreskin too small openings of children before seven years old and glans penis can not be exposed, carrying out preputial ringGlans penis cover must be installed when cutting operation by way of making gap.This process increases operating time, cause due toThe extra bleeding sheared and produced, adds the pain of patient.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of foreskin Endo-GIA, and the foreskin Endo-GIA is in handForeskin gap need not be sheared during art, it is to avoid extra operating procedure, reduce extra operating time and wrapped by shearingPain and operative hemorrhage that skin gap is caused.
The technical solution of the present invention is to provide a kind of foreskin Endo-GIA with following structure, foreskin cuttingStapler, including main body, foreskin fixation kit, cutting assembly and nail bin groupware；Described main body is provided with cavity, the one of the main bodyEnd is provided with opening；Described foreskin fixation kit includes glans penis cover；Described glans penis cover is contained in described cavity；DescribedNail bin groupware includes cartridge body and multiple anastomosis staples；In described cartridge body groove is followed closely provided with multiple radial directions；Described coincideNail is arranged in corresponding nail groove；Described cartridge body is fixed on the openend of described main body；Described cartridge body withRing-type slide rail space is formed between main body, described ring-type slide rail space is connected with body cavity and nail groove；Described cuttingComponent includes cuts main body and cutter, and described cutter are in described cuts main body；Described cuts main body is slidedCoordinate in described ring-type slide rail space, described cutter are stretched into described body cavity and the end of the cutter is supportedOn described foreskin fixation kit；Ejector pin portion is additionally provided with described cuts main body, described ejector pin portion is used for anastomosis stapleRadially push nail groove.
After above structure, foreskin Endo-GIA of the invention, compared with prior art, with advantages below：
Due to cutter and anastomosis staple the setting in the radial direction in foreskin Endo-GIA of the foreskin Endo-GIA of the present inventionPut, cutter are stretched into described body cavity and the end of the cutter is against on the outer surface of described glans penis cover, are disappearedLoop configuration except highlighting glans penis cover surface in the prior art, substantially reduces the diameter of glans penis cover.Adopt the structureAfterwards, the control of foreskin Cutting Length is on the one hand conducive to, while foreskin gap need not be sheared, it is to avoid extra operating procedure,Reduce extra operating time and the pain and operative hemorrhage that are caused by shearing foreskin gap.
