Abstract
The utility model discloses a purse-string forceps anastomat, which belongs to the field of medical equipment. The purse-string forceps anastomat comprises a nail box assembly and a push-nail seat assembly positioned at the front part, and upper and lower forceps handles positioned at the middle part. The purse-string forceps anastomat is characterized in that the push-nail seat assembly at the front part is positioned under the nail box assembly; and the nail box assembly and the push-nail seat assembly are fixed on the upper and lower forceps handles respectively. Because a push-nail seat made of stainless steel is durable and does not deform, a titanium nail in the nail box assembly can effectively nail the corresponding tissue; when the purse string is tensioned, the titanium nail is not pull out; and meanwhile, because the tissue is nailed, each layer of tissue is effectively driven into the purse, and the purse-string forceps anastomat facilitates effective healing of the tissue after anastomosis.
Description
Background technology
This utility model belongs to medical instruments field, specially refers to a kind of pocket pincers anastomat that is used for surgical operation.
Background technology
In medical science applied surgical operation, since the first seam nail series products of the invention sixties in 20th century, medical anastomat has become the requisite a kind of medical apparatus and instruments that aids in the tissue apposition process.Along with the development and the research and development of products of medical science, more and more multi-functional seam nail series products is applied to clinical.The scope of application has related to every field such as gastrointestinal surgery, Genneral Surgery, thoracic surgery, Urology Surgery, department of obstetrics and gynecology, becomes one of doctor's necessary tool.Thereby for the patient have less hemorrhage, less operating time in the art, with apparatus replace manual reduce because the manual error that causes, avoid infection, multiple advantage such as the postoperative function recovery is fast.For diffusion and the cross infection that prevents pathogenic bacteria, this class apparatus generally mostly is disposable use.Therefore high-quality anastomosis become one of key of guaranteeing the surgical operation success, and the high-quality of anastomosis has closely-related the contact with employed anastomat structure again.As main medical apparatus and instruments one of the pocket anastomat, be applied in a plurality of fields such as human body alimentary canal operation widely.It is local clearly inadequately to be specially adapted to operated interface portion bit comparison weak point or sight line, and these places will rely on above-mentioned anastomat to realize the intact stitching of wound energetically.
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.
Summary of the invention
This utility model technical issues that need to address are, in existing pocket pincers anastomat, its nail supporting base part is in use yielding, often causing stitching nail only penetrates by the part level of seam when injected organism tissue, when tightening up pocket, easily cause purse wire fixing tight and come off, in order to overcome this defective, just need the structure division of nail supporting base in the redesign pocket pincers anastomat.The purse wire that makes it guarantee to be stapled to the body tissue surface in operation can freely be twitched, and can not come off; The titanium nail is drawn out.
The purpose of this utility model is, a kind of pocket pincers anastomat is provided, in order to realize the purpose of this utility model, the technical scheme that is adopted is as follows, a kind of 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 forward nail supporting base assembly, be positioned at the below of nail cartridge component, this nail cartridge component and nail supporting base assembly are separately fixed on the lower plier handle.Described forward nail supporting base is the folding bending of double concave, with boat nail cartridge component interlock mutually on it; 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.
Description of drawings
Fig. 1 is pocket pincers anastomat population structure sketch map;
Fig. 2 is nail cartridge component and the local enlarged diagram of nail supporting base assembly.
The specific embodiment
With reference to Fig. 1, represent a kind of pocket pincers anastomat population structure sketch map of the present utility model, being positioned at forward among the figure is nail cartridge component 1, below symmetric with it is nail supporting base assembly 2, what be positioned at the middle part is respectively lower plier handle 4 and upper plier handle 5, rotary part at upper plier handle 5 is provided with pin 3, and the rear portion of this pincers handle 5 is provided with safety block 6.With reference to Fig. 2, be the local enlarged diagram of Fig. 1, the position relation of expression nail cartridge component and nail supporting base assembly can be seen by figure, nail supporting base be in the nail cartridge component 1 under, and be fixed on the vice body of lower plier handle 4, during use, be placed on corresponding tissue, open the part safety block No. 6, hold the hole by the handle on 4, No. 5 parts and clamp, make the titanium nail of No. 1 part excite incidental purse wire on No. 1 part is stapled to tissue surface, unclamp 4, No. 5 parts and withdraw from apparatus and finish; Change No. 1 part, repeat aforesaid operations in symmetric position.Guarantee that the purse wire that is stapled to tissue surface can freely twitch, with two purse wires knottings and tighten up, finish the operation of playing pocket.
Claims (2)
1. a pocket pincers anastomat comprises being positioned at forward nail cartridge component and nail supporting base assembly, is positioned at the last lower plier handle at middle part, it is characterized in that, forward nail supporting base assembly is positioned at the below of following closely cartridge component, and this nail cartridge component and nail supporting base assembly are separately fixed on the lower plier handle.
2. pocket pincers anastomat according to claim 1 is characterized in that described forward nail supporting base is the folding bending of double concave, with boat nail cartridge component interlock mutually on it; This metal material is chosen for rustless steel.
