Compared with the prior art, the device is applied to operation of first-stage protective stoma, the operation effect completely equals to a traditional terminal ileum or transverse colostomy, a second-stage operation return is not required, so that physiological, psychological and economical burden of a patient are lightened, the operation appliance is simple and easy to use, and the device is convenient to popularize.
Description
Technical field
The present invention relates to a kind of surgery device that is used for fistulation, especially relate to a kind of biodegradable intestinal ostomy appliance.
Background technology
In the orthopaedic surgical operations clinical position; Numerous disease; For example: behind the low anastomosis of rectal cancer or the low Low Level anastomosis,, need do preventative colon or ileum protectiveness fistulation usually if the patient has when anastomotic leakage possible taken place coincideing dissatisfied or suspecting; In view of the ileum fistulation is easy to nursing relatively; So the increasing proportion of ileum fistulation in recent years, but traditional ileum fistulation needs after 3 to 6 months the row second operation also receive, at physiology, still all the patient is caused very big influence and burden economically psychologically.Along with the appearance of degradable anastomosis ring, we have invented a kind of use degradable anastomosis ring and have cooperated condom in the process of using in recent years; First phase protectiveness fistulation is made in the application of general drainage pipe, and the degradable anastomosis ring needs 2～3 all cracking usually, is enough to make anastomotic stoma to ride out critical days, can reach the purpose of protectiveness fistulation, also can avoid the strike of second operation.But the intestinal ostomy appliance that anastomosis ring, condom, general drainage pipe are combined into, " cooperation " therebetween often are not to coordinate very much, the effect of influence operation sometimes.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
A kind of biodegradable intestinal ostomy appliance (GE-I type), its structure is as shown in Figure 1, and this device comprises a side-to-side anastomosis mechanism 1 that is positioned at the identical function of enteric cavity band intestinal, and the tail side drain mechanism 2 that connector is inside and outside is positioned at external collection excrement mechanism 3.The similar anastomosis ring of side-to-side anastomosis mechanism 1 shape, front and rear are provided with front end dome 11 and rear end dome 13 respectively, offer hollow slots on the dome; Two domes connect through the cylinder groove 12 of hollow, and the rear design of this cylinder groove 12 becomes to have the tail side that can connect drain portion, tail side band external screw thread; Tail side and main ring junction are designed with indenture; Be convenient to after the cracking in the dialysis of tail side, its material of head can be by the acid of 87.5wt% Polyethylene Glycol and 12.5wt% Barium Sulfate structure, Barium Sulfate radiopaque; The postoperative check can be developed; Fragment or dissolving are voluntarily resolved in Polyethylene Glycol acid after (2～3 weeks of postoperative) through after a while, excrete with stool, and it is residual that anastomotic position does not have any foreign body.The requirement of tail side drain mechanism 2: 1, the about 20cm of length; 2, an end band female thread is used for the external screw thread of union joint side-to-side anastomosis mechanism 1, and an end band external screw thread is used for external connection collection excrement mechanism 3, and it is horn-like that tail side drain mechanism 2 enlarges for inner chamber step by step, helps intestinal contents and draw; 3, the drainage tube intracavity diameter is slightly less than head medium pore 11, and medial surface requires smooth, and surface tension is little, helps intestinal contents and flows out.4, the tube wall of drainage tube can not be too thick, the about 6～8mm of drainage tube external diameter, and require that certain suppleness and hardness are arranged, can make up by materials such as silica gel or PVC.External collection excrement mechanism 3 similar disposable urine drainage bags, but need to satisfy: anterior band female thread can connect the external screw thread of tail side drain mechanism 2; The drainage tube internal diameter is about the external diameter of tail side drainage tube; The other end is disposable for collection excrement mechanism 3 together with the external drainage pipe, can be made up by plastic material.
Seeing that need the disease of row protectiveness ileum, colostomy more; We are example with the sufferer of the capable peritoneoscope DIXON of Low Rectal radiotherapy postoperative art only, introduce the concrete operations step that biodegradable intestinal ostomy appliance (GE-I type) carries out the preventative fistulation of first phase ileum.
1. after accomplishing peritoneoscope radical resection of rectal carcinoma (DIXON art), propose terminal ileum, measure the ileum diameter through the hypogastric region otch; Confirm the model of a side-to-side anastomosis mechanism 1, ileum is made a belt pocket to mesentery edge intestinal wall apart from ileocecus 20cm place, vertically cuts the about 2cm of intestinal wall; Insert a side-to-side anastomosis mechanism 1 to proximal small bowel, apart from the about 5cm of cutting section place, the free about 0.5cm of mesostenium edge herein; Pass absorbable suture, the ligation small intestinal between side-to-side anastomosis mechanism 1 two ends, a closed side-to-side anastomosis mechanism 1; Mechanism inserts from the intestinal wall cutting section with the drain of tail side, and is connected pocket inverting suture intestinal wall cutting section with a side-to-side anastomosis portion spiral; Abdomen Trocar draws outside the abdominal cavity in the hole from the bottom right with tail side drain mechanism 2 other ends, fixes with abdomen wall sewing around the intestinal wall cutting section, utilizes part intestinal wall and stomach wall with the about 2～3cm of tail side drain mechanism's embedding; The outer fixedly drainage tube of sewing up of stomach wall, spiral connects collection excrement mechanism 3, accomplishes the preventative fistulation of ileum.
2. postoperative is gone abdominal plain film examination weekly to dynamic observe the anastomosis ring situation, after the complete disintegrate of discovery anastomosis ring (about 3 weeks of postoperative), pulls out drainage tube; After changing dressings, the stomach wall wound cures.
A kind of biodegradable intestinal ostomy appliance (GE-II type); This device is for a side-to-side anastomosis mechanism 1, and its structure is shown in Fig. 2～3, and a side-to-side anastomosis mechanism 1 is shaped as the anastomosis ring structure; Front and rear is provided with front end dome 11 and rear end dome 13 respectively; Offer hollow slots on the dome, two domes connect through the cylinder groove 12 of hollow, and the rear portion of this cylinder groove is membranaceous full-closed structure.The regularly degraded of 2～3 week of material back of side-to-side anastomosis mechanism 1, its material is by acid of 87.5wt% Polyethylene Glycol and 12.5wt% Barium Sulfate structure.
During use the biodegradable intestinal ostomy appliance of GE-II type is placed ileum,, cause blocking fully of terminal ileum, use drainage tube at its near-end intestinal contents is derived external getting final product through having membranaceous full-closed structure.
