Technical Field

The utility model relates to a clinical medical instrument technical field, more specifically relates to the utility model relates to a when peritoneal metastasis merges small intestine multi-section to colorectal cancer and blocks, be used for the intestinal obstruction pipe that the small intestine was arranged in the operation.

Background

Multiple segments of small intestinal obstruction are one of the main causes of death in peritoneal metastasis of intestinal cancer. Excision of small intestine, arrangement of small intestine and decompression of small intestine are important methods for treating intestinal cancer peritoneal metastasis with intestinal obstruction. Through ilering the near-end in the art and implanting the small intestine and arranging the pipe, reach the ileocecal part through the stoma department, can avoid cutting off the small intestine by a large scale, avoid short bowel syndrome, can alleviate intestinal obstruction and can prevent to be blocked again after the small intestine is arranged, improve nutrition, prolong patient's life. Traditional anus or oral cavity ileus pipe need implant with the help of the scope under the X line perspective, and the radiation is big and drop easily, often fails because of implanting the position is unsatisfactory to multi-section small intestine obstruction, and the pipe can not be antibiotic, and the easy secondary intestinal bacterium shifts to infect, and the pipe material is rough on the hard surface partially, is difficult for implanting, also is difficult for taking out after the implantation, causes the small intestine to perforate easily. Meanwhile, the traditional ileus catheter does not support drug and nutrient injection either.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming above-mentioned prior art's at least one not enough, provide a ileus pipe for the small intestine is arranged, ileus pipe for the small intestine is arranged can be used for the intestinal decompression, effectively alleviates the multiunit section small intestine that the intestinal cancer peritoneum shifted and blocks, still has super-smooth and antibacterial property, and the operation is convenient, can restrain the intestinal bacterium and multiply at pipe surface field planting, prevents the intestinal bacterium and shifts. Meanwhile, the intestinal obstruction catheter can be used for injecting medicines and nutrients.

The utility model adopts the following technical scheme:

the utility model provides an ileus pipe for small intestine range, includes the pipe, is located the pipe head of pipe front end, is located the gasbag valve of pipe tail end to and locate the gasbag on the pipe, the pipe includes pipe wall and pipe appearance chamber, be equipped with 3 passageways in the pipe wall, be seal wire passageway, gasbag passageway and medicine/nutrient passageway respectively, the seal wire has worn the seal wire in the seal wire passageway, and seal wire one end is connected with the pipe head, pipe wall surface scribbles smooth coating, pipe wall surface scribbles with the antibiotic, be equipped with a plurality of through-holes on pipe head and the pipe wall.

A ileus pipe for small intestine is arranged can be followed and is blocked the near-end and implant, it gets into the distal end to make mouthful near-end pass through making mouthful department through the small intestine, wherein the seal wire can be at seal wire passageway internalization, because the one end and the pipe head of seal wire are connected, the seal wire itself has certain rigidity, the pipe head motion can be controlled through the other end of control seal wire to the doctor, make the pipe head can control the luffing motion about in the intestinal, also can be forward or backward motion, conveniently pass a plurality of stages and block the position, thereby conveniently control ileus pipe arrival target location, need not to implant with the help of the scope under the X line perspective, reduce the radiation.
