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 for fistulation, especially relate to a kind of biodegradable intestinal ostomy appliance.
Background technology
In surgical clinic work; numerous disease; for example: after the low anastomosis of rectal cancer or low Low Level anastomosis; if the patient is to coincideing dissatisfied or suspecting when anastomotic leakage possible arranged; usually need do preventative colon or ileum protectiveness fistulation; in view of the ileum fistulation is easy to nursing relatively; therefore the increasing proportion of ileum fistulation in recent years; but traditional ileum fistulation need be gone second operation and also be received after 3 to 6 months, at physiology, still all the patient is caused to very large impact and burden economically psychologically.Along with the appearance of degradable anastomosis ring, we have invented a kind of use degradable anastomosis ring and have coordinated condom in the process of application in recent years; The application of general drainage pipe, make first phase protectiveness fistulation, and the degradable anastomosis ring needs cracking in 2～3 weeks 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 is not often to coordinate very much, the effect of impact operation sometimes.
Summary of the invention
Purpose of the present invention be exactly in order to overcome the defect that above-mentioned prior art exists, provide a kind of simple in structure, without any residual biodegradable intestinal ostomy appliance.

The accompanying drawing explanation
Fig. 1 is structural representation of the present invention in embodiment 1;
Fig. 2 is main TV structure schematic diagram of the present invention in embodiment 2;
Fig. 3 is plan structure schematic diagram of the present invention in embodiment 2.
In figure, 1 is that a side-to-side anastomosis mechanism, 11 is that front end dome, 12 is that cylinder groove, 13 is that rear end dome, 2 is that tail side drain mechanism, 3 is for collecting excrement mechanism.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
A kind of biodegradable intestinal ostomy appliance (GE-I type), as shown in Figure 1, this device comprises and is positioned at enteric cavity with the coincide side-to-side anastomosis mechanism 1 of function of intestinal its structure, the tail side drain mechanism 2 that connector is inside and outside, be positioned at external collection excrement mechanism 3.The similar anastomosis ring of side-to-side anastomosis mechanism 1 shape, front and rear arranges respectively front end dome 11 and rear end dome 13, offer hollow slots on dome, two domes connect through the cylinder groove 12 of hollow, the rear design of this cylinder groove 12 becomes with the tail side that can connect drain section, tail side band external screw thread, tail side and main ring junction are designed with indenture, be convenient to after cracking in the dialysis of tail side, its material of head can be built by 87.5wt% polyglycolic acid and 12.5wt% barium sulfate, the barium sulfate radiopaque, postoperative check can be developed, polyglycolic acid resolves into fragment or dissolves voluntarily after (postoperative 2～3 weeks) through after a while, with stool, excrete, anastomotic position is residual without any foreign body.The requirement of tail side drain mechanism 2: 1, the about 20cm of length; 2, an end band female thread, for the external screw thread of union joint side-to-side anastomosis mechanism 1, an end band external screw thread, for external connection collection excrement mechanism 3, it is horn-like that tail side drain mechanism 2 enlarges step by step for inner chamber, is conducive to intestinal contents and draws; 3, the drainage tube intracavity diameter is slightly less than head medium pore 11, and medial surface requires smooth, and surface tension is little, is conducive to intestinal contents and flows out.4, the tube wall of drainage tube can not be too thick, and the drainage tube external diameter is 6～8mm approximately, and require that certain suppleness and hardness are arranged, and can be built by materials such as silica gel or PVC.External collection excrement mechanism 3 similar disposable urine drainage packs, but need to meet: 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, for collection excrement mechanism 3, is disposable together with the external drainage pipe, can be built by plastic material.
In view of the disease of the capable protectiveness ileum of needs, colostomy more; we only take the sufferer of the postoperative row peritoneoscope of Low Rectal radiotherapy DIXON art is example, introduces the concrete operation step that biodegradable intestinal ostomy appliance (GE-I type) carries out the preventative fistulation of first phase ileum.
1. after completing radical operation of rectal carcinoma by laparoscopy (DIXON art), through the hypogastric region otch, terminal ileum is proposed, measure the ileum diameter, determine the model of a side-to-side anastomosis mechanism 1, apart from ileocecus 20cm place ileum, mesentery edge intestinal wall is made to a belt pocket, vertically cut 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, through absorbable suture, the ligation small intestinal is between side-to-side anastomosis mechanism 1 two ends, a closed side-to-side anastomosis mechanism 1, tail side drain mechanism is inserted from the intestinal wall cutting section, and be connected with a side-to-side anastomosis section spiral, pocket inverting suture intestinal wall cutting section, tail side drain mechanism 2 other ends are drawn abdominal cavity from Right Lower Abdomen Trocar hole, intestinal wall cutting section surrounding and abdomen wall sewing are fixed, utilize part intestinal wall and stomach wall by the about 2～3cm of tail side drain mechanism embedding, the outer fixedly drainage tube of sewing up of stomach wall, spiral connects collection excrement mechanism 3, complete the preventative fistulation of ileum.
2. postoperative capable abdominal plain film examination weekly, dynamically to observe the anastomosis ring situation, after the complete disintegrate of discovery anastomosis ring (approximately postoperative 3 weeks), is pulled out drainage tube; After the stomach wall Wound during Dressing Change, cure.
Embodiment 2
A kind of biodegradable intestinal ostomy appliance (GE-II type), this device is a side-to-side anastomosis mechanism 1, its structure is as shown in Fig. 2～3, side-to-side anastomosis mechanism 1 is shaped as the anastomosis ring structure, front and rear arranges respectively front end dome 11 and rear end dome 13, offer hollow slots on 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 material of side-to-side anastomosis mechanism 1 is regularly degraded after 2～3 weeks, and its material is built by 87.5wt% polyglycolic acid and 12.5wt% barium sulfate.
During use, the biodegradable intestinal ostomy appliance of GE-II type is placed in to ileum, by the full-closed structure with membranaceous, causes blocking fully of terminal ileum, at its near-end application drainage tube, intestinal contents is derived to external getting final product.
