Abstract

The utility model discloses an electric flexible end-to-end-intestinal anastomat for a surgical intestinal surgery. The anastomat comprises a nail propping seat and an anastomat main body which is clamped with the nail propping seat, wherein the anastomat main body comprises a guide wire pulling nail propping seat device, an electric closing device which is arranged in the inner part of a nail cabin shell and an electric control gear which is connected with the electric closing device. Aiming at the defect that a conventional anastomat can not be bent in an intestinal tract, the flexible intestinal anastomat is provided, and an aluminum bent pipe part of the anastomat is changed into a rubber hose, so that the flexibility of the device can be greatly enhanced; and meanwhile, the two broken ends of the intestinal canals are innovatively and tightly stretched through a pulling guide wire, and then the anastomotic way is finished by an electric device, so that the automation of the anastomosis of intestines can be realized; furthermore, the defect that the surgery of colon sigmoideum or descending colon or transverse colon needs end-to-side anastomosis can be changed, and the end-to-end anastomosis can be directly carried out, so that the surgery time can be saved, the probability of intestinal fistula can be reduced, the continuous physiological structures of the intestinal canals can not be changed, and the efficiency of the operation can be improved.

Description

The electronic soft bar intestinal EEA surgical stapler that a kind of surgery intestinal surgery uses

Technical field

This utility model relates to a kind of intestinal EEA surgical stapler, the electronic soft bar intestinal EEA surgical stapler that especially a kind of surgery intestinal surgery uses.

Background technology

anastomat is the equipment that the alternative traditional-handwork that medically uses is sewed up, the anastomat reliable in quality of using clinically at present, easy to use, tightly, degree of tightness is suitable, especially it is sewed up fast, easy and simple to handle reaching seldom has the advantages such as side effect and postoperative complication, but at present, disposable circular anastomosis device is because of metal or hard plastic shell, when only being expert at operation on rectum, but the capable rectum of per anum, " end end " between sigmoid colon coincide, the sigmoid colon of being expert at, when descending colon and transverse colon operation, during the capable intestinal canal anastomosis of removal of lesions was intestinal tube, all in abdominal cavity row end-to-side anastomosis, another colon stump need be closed with the straight line closer like this, so just increased the probability of intestinal fistula, increase simultaneously operating time, more intestinal pipe need dissociate during operation, so that " distolateral " coincide, the existing soft bar bowel anastomosis of the surgical electric device transverse colon of being expert at, descending colon, during operation on sigmoid, can enter the intestinal pipe as the intestinal mirror, be connected the end to end anastomosis between the row intestinal tube with the near-end nail supporting base, reduced the occurrence probability of intestinal fistula, save operating time, intestinal canal anastomosis when being convenient to laparoscopic surgery, make abdominal operation incision more " Wicresoft ", do not change simultaneously the seriality of intestinal tube, not residual on intestinal " pouch ".

In the prior art, the electronic stapling apparatus of part is disclosed, though realize automation mechanized operation, but when screwing two broken ends of fractured bone intestinal tubes, more need be accurate operation, the manual operation positive effect will be got well, and more conventional the coincideing of disclosed electronic anastomat there is no revolutionary change simultaneously, only realized merely operation automation.

The utility model content

For addressing the above problem, this utility model provides a kind of automaticity electronic soft bar intestinal EEA surgical stapler that surgery intestinal surgery high, easy to use uses.

Realize the electronic soft bar intestinal EEA surgical stapler of a kind of surgery intestinal surgery use of this utility model purpose, comprise nail supporting base and the stapler main body that can engage with nail supporting base, described stapler main body comprises seal wire tractive nail abutting seat device, is arranged on the electronic closing device and the electric control gear that is connected with electronic closing device of nail bin enclosure.

Described seal wire tractive nail abutting seat device is manually, comprises the adjusting nut, drive screw, tractive seal wire, return spring, the built-in slide-and-guide axle that connect successively, and wherein built-in slide-and-guide axle comprises puncture axle and rubber piston handle; Described drive screw is arranged in handle casing; Described tractive seal wire outer wrap has the seal wire cover, and described seal wire cover and electric wire all are wrapped in the soft bar of rubber; Described return spring, built-in slide-and-guide axle are installed in stationary pipes, and stationary pipes can also limit its disengaging after puncture axle and nail supporting base jump ring duct ligation close simultaneously.

Temporary fixed in stationary pipes of built-in slide-and-guide axle is two groups of jams by the stationary pipes inwall, above one group the gear in rubber piston handle upper end, avoid it to slide outside stationary pipes, below one group of jam be embedded in rubber piston handle sidewall, after stressed tractive, the rubber piston handle can break away from this jam, and its resistance is slightly larger than the resistance of nail supporting base when the puncture axle of built-in slide-and-guide axle is combined.

Stretch out in puncture axially, a little more than nail bin shell horizontal plane, damage intestinal wall in the time of so neither can be in putting in intestinal tube more makes when connecting nail supporting base the location easily.

Described electronic closing device comprises the miniature hollow motor that is made of stator and sleeve rotor, and described stator inner wall is equipped with sleeve rotor, described sleeve rotor by screw thread with promote pipe and be connected, described promotion pipe top is equipped with nail bin and endless knife.

Described electric control gear comprises power supply, control panel and action button, action button is comprised of the close push button and the release button that are arranged on control panel, power pack can be cell apparatus, also can be external AC power supply, described control panel is connected with miniature hollow motor in electronic closing device by power line.

This patent can not provide a kind of soft bar bowel anastomosis device in the deficiency of intestinal bending for conventional anastomat, changes the aluminum bent tube section of anastomat before into rubber hose, has strengthened greatly motility and the comfortableness of device; Simultaneously, after pass through the tractive seal wire and strain two broken ends of fractured bone intestinal tubes of innovation, complete identical mode by electric device again, realized that the automatization of intestinal canal anastomosis carries out, changed the shortcoming that sigmoid colon in the past or descending colon, transverse colon operation need end-to-side anastomosis, direct end to end anastomosis, save operating time, lower the intestinal fistula probability, do not change intestinal tube seriality physiological structure, improve operation efficient, alleviated the patient suffering; This patent overall structure is simple and reliable, design is ingenious, is conducive in each medical institutions' large-scale promotion and use.
