Be provided with the annular tool rest that is enclosed within on the short tube in the tubaeform sleeve pipe, this annular tool rest is provided with projection, endless knife one end that is contained in the tubaeform sleeve pipe is a blade, its other end has in-flanges, this in-flanges be provided with sleeve pipe annular tool rest on protruding quantity equate and the corresponding slotted eye in position, and in the annular tool rest projection insertion endless knife in-flanges slotted eye and fix.
One end of shell is a link, and link of the present utility model is furnished with anastomat muzzle joint.Because this utility model is the requisite critical piece of bend pipe or straight tube anastomat, and be disposable use thing, therefore this utility model has four kinds of different technical schemes with the connection of anastomat: the technical scheme 1 that link connects: anastomat muzzle joint is provided with open channel, on the link of shell one end, be provided with flange, and clamping mutually.Technical scheme 2: be provided with inside groove and hole at the shell link, be provided with gap between inside groove and the hole, and with the anastomat joint on the flange clamping.Technical scheme 3: the shell link is provided with L shaped open channel, and anastomat muzzle joint is provided with inward flange and clamping mutually.Technical scheme 4: establish inside groove and hole on the shell link, between inside groove and the hole gap is arranged, anastomat muzzle joint is provided with flange and clamping mutually.
When bend pipe or straight tube anastomat connect the muzzle joint, and with after this utility model is connected, the anastomat ejector sleeve promotes the sleeve pipe in this utility model shell, move forward along with telescopic, the cannula push needle sheet is pushed out to identical the fusing of tissue that nail supporting base will be sewed up with the anastomosis staple in the annular nail bin, simultaneously, endless knife is excised excess tissue, finishes rapidly and coincide and resection operation.
This utility model compared with prior art has following advantage:
1, this utility model adopts medical surgical instrument to replace time-consuming, effort, loaded down with trivial details manually-operated operation, has simplified operation technique, has shortened operating time, and then has reduced complication rate.
2, this utility model practicality rational in infrastructure, in light weight, use sensitivity reliable, it is circular to guarantee to coincide, and the anastomotic stoma after coincideing can be born and is not less than 3.6 * 10
3Pa pressure, water-tight, do not tear.
3, being connected of link of the present utility model and anastomat muzzle joint, have the locking effect, after flange enters slotted eye, can see the locking situation that puts in place, guaranteed operation success smoothly.
