Description
Technical field
The present invention relates to a kind of anastomosis apparatus, especially relate to a kind of invagination type glue ring lock catch fixed intestines fitting ring that is used for the gut surgery after the total gastrectomy.
Background technology
After the total gastrectomy operation, must carry out coincideing between intestinal portion and the esophagus, but after existing anastomat coincide, anastomotic fistula, anastomotic stricture often occur, backflow and influence complication such as food passes through, and existing anastomat expense be higher.
The tubulose stapler formula anastomat of using (for example CDH25 type anastomat of Johnson Co.'s product) is to turn over double peg stitching in the far and near intestinal tube together at present, therefore the narrow ring that the healing back forms no Telescopic causes anastomotic fistula, anastomotic stricture, backflows and influences complication such as food passes through.
Summary of the invention
The objective of the invention is to the deficiency that exists at anastomosis apparatuses such as existing tubulose stapler formula anastomats, provide that a kind of postoperative intestinal anastomotic stoma leakage, no anastomotic stricture do not take place, backflows less, content does not have the invagination type glue ring lock catch fixed intestines fitting ring that foreign body is residual, medical expense is lower by smooth and easy, anastomotic stoma.
The present invention is provided with: elastic ring, internal ring and outer shroud, the internal ring bottom is provided with inwardly groove of annular, the internal ring inboard is provided with loop-hook, the outer shroud bottom is provided with the annular outer groove, the outer shroud lower inside is provided with at least 2 barbs, and the barb of being located at the outer shroud lower inside forms snap close with the loop-hook of being located at the internal ring inboard.
On elastic ring, preferably be provided with ring-shaped groove, to prevent the intestinal wall ischemia.Can be provided with hollow hole on the internal ring ring wall, hollow hole is preferably established 6 at least, and the claw type hook can be established in the outer shroud middle and lower part, and the claw type hook is preferably established 6～8.
Elastic ring preferably adopts rubber ring.Be located at the barb of outer shroud lower inside and preferably establish 6～8.
During use, because esophagus or thin intestinal tube are placed in interior ring surface, the intestinal tube section can be fixed in internal ring lower end groove with absorbable thread, the small intestinal section is pricked fixing with absorbable thread and rubber circumferential weld, place rubber ring in the annular outer groove of outer shroud bottom together with the intestinal wall ecto-entad, internal ring is inserted to outer shroud, make the loop-hook of internal ring inboard and the barb of outer shroud lower inside form snap close, rubber ring is fixed between internal ring and the outer shroud, make internal ring, outer shroud and far and near intestinal tube form stable fixed structure, far and near end intestinal tube promptly forms sleeve type and coincide, and the intestinal wall serous coat contacts with serous coat, about 1～1.2 centimetre of interface width.Usually internal ring and outer shroud can decompose automatically after 10 days and come off, and per anum is discharged, after rubber ring comes off also per anum discharge, esophagus forms sleeve type with intestinal tube and heals.The advantage of this healing is no narrow, ne-leakage, anti-backflowing, and can not influence passing through of food simultaneously, and anastomotic stoma does not have foreign body residual.Therefore adopt the method for being inserted in, cover colludes the lock connection mutually, fixed three loops of middle elastic ring (or claiming doubling ring) close by internal and external double-circular, be convenient to the contact of intestinal serous coat, make thin or the near-end intestinal tube is fixed with the internal ring binding, the far-end intestinal tube is put into by elastic ring and is fixed with inner and outer ring, far and near intestinal tube is inserted in fixing healing, no stitching.

The specific embodiment
Following examples will form structure of the present invention in conjunction with the accompanying drawings and using method is further described.
Referring to Fig. 1～7, the present invention is provided with elastic rubber ring 1, internal ring 2 and outer shroud 3.Internal ring 2 bottoms are provided with inwardly groove 21 of annular, and internal ring 2 lower inside are provided with loop-hook 22.Outer shroud 3 bottoms are provided with annular outer groove 31, and outer shroud 3 lower inside are provided with 6～8 barbs 32.The barb 32 of being located at outer shroud 3 lower inside forms snap close with the loop-hook 22 of being located at internal ring 2 inboards.
On elastic rubber ring 1, be provided with some ring-shaped grooves 11, to prevent the intestinal wall ischemia.Be provided with at least 6 hollow holes 23 on internal ring 2 ring walls, outer shroud 3 middle and lower parts are provided with 8 claw type hooks 33.
During use, earlier esophagus or thin intestinal tube 5 are placed in internal ring 2 surfaces, esophagus or intestinal tube 5 sections are fixed in internal ring 2 lower end grooves 21 with absorbable thread; After again small intestinal 4 sections being fixed with absorbable thread and rubber circumferential weld bundle, rubber ring is placed in the outer shroud together with the intestinal wall ecto-entad, rubber ring promptly is placed in the outer tongue of outer shroud, to push in the outer shroud with esophagus or the thin fixed internal ring of intestinal tube, and make the loop-hook of internal ring inboard and the barb of outer shroud lower inside form snap close.At this moment, rubber ring also is fixed between the annular outer groove of being located at the outer shroud bottom and the loop-hook of being located at the internal ring inboard, make internal ring, outer shroud and far and near intestinal tube form stable fixed structure, far and near end intestinal tube promptly forms sleeve type and coincide, the intestinal wall serous coat contacts with serous coat, about 1～1.2 centimetre of interface width.
Usually internal ring and outer shroud can decompose the also per anum discharge that comes off automatically after 10 days, and per anum was discharged after rubber ring came off, and esophagus and intestinal tube form sleeve type and heal.The advantage of this healing is no narrow, ne-leakage, anti-backflowing, and can not influence passing through of food simultaneously, and anastomotic stoma does not have foreign body residual.
