Description
Technical field:
This utility model belongs to surgical medical equipment technical field, is specifically related to the identical auxiliary suture device of a kind of degradable.
Background technology:
Surgeon, after carrying out the Partial Resection of the human body cast tissues such as intestinal tube, biliary tract, need to connect two broken ends of fractured bone, completes the reconstruction of cast tissue.Usual way is to use classical anastomosis to carry out manual suture with silk thread or catgut; although the manual identical method of this class is easy to learn; but complicated operation; the time of coincideing is long; anastomotic stoma is irregular; and anastomotic stoma can not get effective protection among being often exposed to enteric cavity, easily cause postoperative anastomotic stoma seepage.The sixties in last century, the invention of the U.S. USSC company surgical stapling device assembly, the closer that released one after another, stapler, gastrointestinal tube type anastomat (EEA), nowadays utilize tube type anastomat to complete coincideing of cast tissue and become basically universal.Tube type anastomat provides double titanium tantalum peg, draws two broken ends of fractured bone cast tissues over to one's side stitching, thereby realize the mechanization of gastrointestinal anastomosis in intracavity.After stitching, each piece of titanium nail is " B " font, guarantees that anastomotic stoma blood vessel passes through, and for anastomotic stoma provides sufficient blood confession, the probability of fistula of operative incision reduced greatly, improved the safety of operation.Tube type anastomat has been expanded surgical operation scope, has shortened operating time, has reduced tissue injury and hemorrhage.But tube type anastomat also has a lot of defects, as anastomat is disposable equipment, expensive; Operation sequence is more loaded down with trivial details, and not reproducible operation; Rectum is above cannot complete end to end anastomosis, needs the capable end-to-side anastomosis of closer, and closed rear stump forms blind pipe diverticulum, does not meet digestive tract physiological structure; Foreign body forever retains body and easily forms larger cicatrix; Anastomotic stoma can not get effectively protection etc.
Chinese patent application 98126516.2 has proposed " a kind of degradable in vivo surgical stapling cover for surgical stapling ".This patent is made protruding cover and recessed cover two parts by Biodegradable material, on recessed body, have sealed groove, at protruding body head with 4 sealed keys, two parts are inserted respectively to be needed in identical intestinal tube and draws over to one's side, the corresponding sealed intestinal that completes of sealed groove of the key of protruding body and recessed body coincide, and the degraded thereupon of the cover material that coincide is cracked and excrete.This identical cover is made more complicated, can not guarantee that anastomotic stoma is smooth, can not effectively protect anastomotic stoma.
Utility model content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of degradable auxiliary manual stapling apparatus is provided, and can obviously accelerate manual suture speed, also can effectively protect the not contaminated degradable of anastomotic stoma to coincide simultaneously and assist suture device.
The technical solution of the utility model: a kind of degradable coincide and assists suture device, comprise recessed and male member by high molecular degradable material, being made, described recessed is tubulose with male member, in one end pipe of described recessed, be provided with step, the outer boss matching with recessed interior step that is provided with of one end pipe of described male member, described recessed and male member can be completely chimeric, described recessed is provided with circular-arc fairlead with the identical end of male member, and mutually corresponding, described fairlead one end is located at the matching surface of described recessed and male member, and the other end is located at the outer surface of described recessed and male member; Described fairlead does not penetrate the inner surface of recessed and male member, guarantees its involutory rear inwall polishing.
Further, the spacing of described fairlead is 1cm, and longitudinally the degree of depth is 0.4cm.
Further, at described recessed, be provided with medication coat with the outer surface of male member.
Further, described medication coat comprises infection, antitumor drug and somatomedin.
1), simple and practical the beneficial effects of the utility model:, can obviously accelerate manual suture speed, the manual requirement that coincide of standard; 2), economical and practical, can not cause the waste of unnecessary dispensable mould consumptive material; 3), can complete complete end to end anastomosis, kept the normal physiological structure of tissue; 4), anastomotic stoma is placed under the protection of degradation material completely, guarantees that it heals safely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of recessed;
Fig. 3 is the structural representation of male member.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is elaborated.
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of degradable coincide and assists suture device, comprise recessed 1 and male member 2 by high molecular degradable material polylactic acid, being made, described recessed 1 and male member 2 are tubulose, in one end pipe of described recessed 1, be provided with step 3, the outer boss 4 matching with recessed 1 interior step 3 that is provided with of one end pipe of described male member 2, described recessed 1 and male member 2 can be completely chimeric, the identical end of described recessed 1 and male member 2 is provided with circular-arc fairlead 5, and mutually corresponding, described fairlead 5 one end are located at the matching surface of described recessed 1 and male member 2, the other end is located at the outer surface of described recessed 1 and male member 2, described fairlead 5 does not penetrate the inner surface of described recessed and male member, guarantees its involutory rear inwall polishing, the spacing of described fairlead 5 is 1cm, and longitudinally the degree of depth is 0.4cm, at described recessed, be provided with medication coat with the outer surface of male member, described medication coat comprises infection, antitumor drug and somatomedin.
While coincideing, described recessed 1 and 2 liang of parts of male member are put into respectively and needed two broken ends of fractured bone tube chambers that coincide, draw close involutory, use the absorbable surgical sutures of antibacterial anti-tensile, along the fairlead 5 designing on described recessed 1 and male member 2, do continuous stitching, slightly tight during last take-up knotting, cause anastomotic stoma to turn in slight, thus the manual suture of performance specification.Because anastomotic stoma is by described recessed 1 and the complete embedding of male member 2, cut off contacting of anastomotic stoma and cavity content, formed the effect as " internal short-circuit ", effectively protected anastomotic stoma.Macromolecule degradable material has certain elasticity, can be used as temporary transient stent support anastomotic stoma, prevents anastomotic stricture contracture; Degradable material also can load infection, antitumor and somatomedin, further consolidates the protection to anastomotic stoma.
This utility model selects polylactic acid as high molecular degradable material, molecular weight 4000-6000, and 2-4 time-of-week is degradable in body is that H2O and CO2 eliminating are external, can not pile up in vivo.
