Abstract

The utility model discloses a complete bypass type intestine fistulization pipe. The pipe comprises a synthetic material pipeline; a deformable air bag is arranged near a front end part of the pipeline; the pipeline is arranged in front of the air bag, so a flow guiding segment is formed; the font part of a slim pipe is arranged in the pipeline in a threaded manner; the front end of the slim pipe passes through the pipe wall of the pipeline and is communicated with an inner cavity of the air bag; the back end of the slim pipe is connected with an air inflation port which is provided with an one-way valve and is used for injecting fluid into the air bag; after the fluid is injected into the air bag via the air injection port, an enclosed structure used for blocking intestinal contents is formed between the air bag and an intestine pipe; and a flow guide mouth used for guiding out the intestinal contents via the pipeline is arranged on the flow guiding segment. According to the utility model, by controlling the press on an intestinal wall imposed by the silica gel air bag, and using the silica gel air bag to block the intestinal contents, the intestinal contents are guided out from the fistulization pipe, so an effect of temporary protection for a far-end anastomotic stoma is achieved. After the far-end anastomotic stoma is healed, by pulling out the fistulization tube, an intestinal stoma will close automatically, so second operation is avoided.

Description

Complete turn of tidal stream type intestine fistulization pipe

Technical field

This utility model relates to a kind of complete turn of tidal stream type intestine fistulization pipe.

Background technology

The postoperative risk that has anastomotic leakage of the capable low anastomosis of rectal cancer; once there is anastomotic leakage, serious complication will be brought; and provisional ileum protectiveness fistulation can play the generation of protection anastomotic leakage; the effect of the complication that reduction anastomotic leakage brings; but at present conventional ileum two-chamber fistulation need to go the Hui Na that performs the operation again; and secondary returning is received complication risks such as existing equally anastomotic leakage, intestinal obstruction; how to go to avoid secondary returning to receive operation; avoid secondary returning to receive brought risk, be the direction that anorectal surgical doctor explores always.

China Patent No. 2011103436269 discloses a kind of temporary ileum ostomy pipe, stoma is positioned in terminal ileum and through outside stomach wall lead body in operation, utilize negative pressure to reach the object outside blocking-up near-end intestinal contents lead body, after fistulation finishes, pipeline can directly be pulled out, ileum wall is put the mouth of pipe and will be healed voluntarily, thereby avoids going back fistula operation.But this technical pattern more complicated, and pipeline is long, and caliber is relatively little, and drain distance is long, turn of tidal stream weak effect.

Summary of the invention

The drain distance, turn of tidal stream weak effect and the more complicated shortcoming of structure that in order to overcome existing stoma, exist, this utility model provides that a kind of turn of tidal stream is effective, fistulization oral auto-closing, avoids the complete turn of tidal stream type intestine fistulization pipe of second operation.

The technical solution adopted in the utility model is:

Turn of tidal stream type intestine fistulization pipe, comprises synthetic material pipeline completely, it is characterized in that: on described pipeline, near front end position, be provided with deformable air bag, the part that described pipeline is positioned at before described air bag forms Drainage Section; The front portion of tubule is located in described pipeline and the front end of described tubule is communicated with through the described tube wall of pipeline and the inner chamber of air bag, the rear end connection of described tubule with one-way cock for the inflatable interface to air bag beam body; Described air bag is formed for blocking the enclosed construction of intestinal contents after inflatable interface fills fluid and between intestinal tube; Described Drainage Section is provided with the draining hole that intestinal contents is drawn by pipeline; Described inflatable interface end is provided with the measuring cell to the pressure of intestinal wall for detection of air bag.

Further, described Drainage Section is to be convenient to the oblique opening that intubate is inserted.

Further, on the tube wall of described Drainage Section, offer and there is the fusiformis side opening of assisting drainage effect.

Further, on the tube wall of described pipeline, offer annular groove, described device for cleaning pipeline is crossed the stator matching with described annular groove and is fixedly connected with stomach wall.

Further, described rear end of pipeline is provided with the trocar sheath of being convenient to pipeline draw stomach wall suitable with it.

This utility model air bag diameter is 4cm, length 5cm, and silica gel material is synthetic, soft, air bag by tubule and the pipeline other end with one-way cock inflatable interface communicate, intestinal tube is produced to pressure, the easy compressive deformation of air bag after filling water/gas, the pressure of reduction to intestinal tube, can play the effect of blocking-up sealing intestinal tube, along with enterokinesia increases, intestinal tube can be expanded gradually simultaneously, air bag also can be out of shape along with dilatation of intestine, postpones Xining.

The concrete operation method of intestine fistulization pipe described in the utility model is as follows:

After rectum has coincide, get terminal ileum apart from ileocecal valve 15cm left and right ileum, 3-0 absorbable thread is made 1cm, 1.5cm size left and right concentric circular pocket, pocket center electric knife is cut the little openning of trying one's best, stoma inclined-plane is inserted to ileum near-end, until air bag tightens up respectively inside and outside pocket after all inserting ileum, notice that outer pocket enters the complete embedding of interior pocket as far as possible.Then from one-way cock water filling, note to control air bag to the pressure of intestinal wall between 20-30cmHg, on stomach wall, do again a 1cm left and right otch, trocar sheath is penetrated from stomach wall to abdominal cavity, by trocar sheath, stoma is drawn to stomach wall, pull out trocar sheath, the small intestinal intestinal wall seromuscular layer of stoma periphery and stomach wall close and fix one week around pipe seam with absorbable thread.The outer stoma of stomach wall connects two-piece type fistulization chassis, and on chassis, the fixing stoma of collar-shaped stator, prevents that stoma from bouncing back, then put fistulization.Postoperative attention monitoring gasbag pressure, along with intestinal tube is expanded gradually, air bag barrier effect can decline gradually, if far-end rectum anastomotic stoma has the generation of leakage, needs to continue to air bag water filling, keeps the closure of air bag, controls gasbag pressure with the delay protection cycle.While not needing fistulation, the air bag of finding time, can pull out stoma.Stoma is pulled out rear fistulation intestinal wall and is automatically healed, and does not need Hui Na again, to reach the object of complete turn of tidal stream.

The beneficial effects of the utility model are embodied in:

1, by controlling the pressure of air bag to intestinal wall, with air bag, block intestinal contents, intestinal content is drawn from stoma, play the effect of temporary protection far-end anastomotic stoma, after far-end anastomotic healing, pull out stoma, fistulization oral auto-closing, has avoided second operation.

2, in this utility model, internal diameter of the pipeline is 75mm, stoma 4mm in prior art, and turn of tidal stream effect and tube chamber area are directly proportional, and guarantee sufficient turn of tidal stream effect.

3, pipeline only has 15cm long, and drain distance is short, effective.

4, can air bag pressure measurement be quantized aerosil cyst wall pressure for the first time, guarantee to control air bag to intestinal wall pressure along with passing through water filling again after intestinal wall expansion, still can play sufficient barrier effect.

5, supporting trocar sheath, stator, easy to use, simple to operate, effective.

6, directly connect the outer fistulization of stomach wall, do not need negative pressure, take food semi-fluid without slag after, turn of tidal stream is effective.
