Abstract

The utility model discloses a blocking catheter used in colonic lumens, which is made of an elastic medical silicone tube. A feces draft tube 6, a medicine flushing tube 5 and air bags 1, 2, 3 made of elastic rubber are arranged on the silicone tube. If adopted, the utility model can eliminate fecal pollution and lower the rates of colonic fistulation, and II period and III period operations. The utility model has the advantages of convenient use and operation and no pains for patients and is suitable for the prevention and treatment of the traumas of anuses and rectums, the blockage of anastomotic fistulae after operations of rectum or sigmoid colon cancer. The tube arranging position is low, so that functions of hearts, lungs and kidneys can not be influenced, no other adverse reaction exists, side effects are few, and the effect is positive.

Description

Occluding catheter in a kind of colonic lumen

This utility model relates to a kind of medical operation utensil, is after being mainly used in prophylactic treatment anus, rectum wound, rectum or sigmoid colon tumor operation the interior occluding catheter of a kind of colonic lumen that fistula of operative incision blocks to take place.

The disease kind that colonic diseases need be performed the operation is more, behind colonic operation, if intestinal is prepared imperfection or blocking because of tumor before the art, reasons such as intestinal commentaries on classics can't be carried out intestinal and be prepared, postoperative feces is deposited in around the anastomotic stoma, and the compressing anastomotic stoma causes ischemia, necrosis, or stimulate and former focus is blocked because of operation, enteric cavity is in expansion state for a long time and influences enterokinesia, feces and gas gather, and the enteric cavity internal pressure increases, and intestinal tube is extremely expanded, anastomotic stoma is torn, all can cause fistula of operative incision, or because of the intestinal mucosa necrosis, come off, the anaerobe breeding is infected in the enteric cavity, and cause enteritis, influence anastomotic healing, or because of fecal bacteria infects, the suture healing is bad, split and the chance of fistula of operative incision more, cause excrement peritonitis, in case it is high that mortality rate takes place, even implemented II phase or III stage operation, therapeutic effect is dissatisfied, so some case is not made the first phase resection and anastomosis, colostomy increases the misery and the financial burden of operation several times to patient in advance.

The purpose of this utility model is exactly to improve I stage operation rate in order to stop fecal pollution, reduces the II phase, III stage operation rate, the generation of prevention fistula of operative incision and occluding catheter in a kind of colonic lumen is provided.

This utility model is achieved in that occluding catheter in a kind of colonic lumen of being made by the elasticity medical silicone tube, it is characterized in that described silica gel tube is provided with the air bag that elastic gum is made, the respectively corresponding gas tube of each air bag, the inlet end of gas tube is provided with seal valve, the silica gel tube center is provided with the feces drainage tube, also be provided with anastomotic stoma drug irrigation pipe in silica gel tube one side, the air bag that can pass through this conduit is with the enteral of the prevention of the feces in the colonic lumen more than anastomotic stoma, unlikely pollution anastomotic stoma, feces can pass through the lavation of feces drain through hole, outside the lead body of dilution back.

Be described in detail this utility model below in conjunction with embodiment and accompanying drawing thereof:

Fig. 1 is a population structure sketch map of the present utility model;

Fig. 2 is the A-A cutaway view of this utility model Fig. 1;

Fig. 3 is the B-B cutaway view of this utility model Fig. 1;

Fig. 4 is the C-C cutaway view of this utility model Fig. 1;

Fig. 5 is the D-D cutaway view of this utility model Fig. 1.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, occluding catheter in the colonic lumen, be by external diameter 15cm, internal diameter 1cm, the elasticity medical silicone tube of long 60cm is made, silica gel tube is provided with the air bag 1 that elastic gum is made, air bag 2, air bag 3,

air bag

1,2, by gas tube 10 inflations, air bag 3 is by gas tube 9 inflations,

gas tube

9,10 end is provided with seal valve 4, the center of silica gel tube is provided with feces drainage tube 6, one end of feces drainage tube 6 has hole 7, also be provided with anastomotic stoma drug irrigation pipe 5 in silica gel tube one side, one end of anastomotic stoma drug irrigation pipe 5 has hole 8, medicinal liquid can inject focus by the hole 8 of drug irrigation pipe 5 one ends, the method of blocking-up intubation catheter and step are with the method for inserting anal canal in the colonic lumen, but carry out under will in operation, looking at straight, intubate air bag 3 is placed the colon anastomotic stoma the upper end apart from anastomotic stoma 10-20cm, by 3 inflations of 9 pairs of air bags of gas tube, the blocking-up colon, not oppress the normal blood circulation of colon and not influence enterokinesia, feces is passed through, it is hollow that operative region keeps, cleaning, pollution-free state, operative region can wash with antibiotic or sterilised liq, to promote the healing of anastomotic stoma, feces can pass through drainage tube 6, excrete after 7 dilutions of

hole.Air bag

1,2 is fixing by gas tube 10 inflations, and occluding catheter is in order to avoid slippage.

This utility model A section 20cm, B section 6cm, air bag 2 accounts for 2cm, C section 32cm, air bag 3 accounts for 5cm, D section 2cm.Putting pipe is fit to keep tube pulling after 5-7 days.

Adopt this utility model to stop fecal pollution; Constant drainage alleviates intraperitoneal pneumatosis, stercoroma and the stomachache that causes, abdominal distention and tear because of the too high anastomotic stoma that makes of enteric cavity internal pressure; Anastomotic stoma zone medication promotes healing; Colostomy and II phase, III stage operation rate have been reduced; Easy for operation, patient's no pain, few side effects, effect certainly, after being adapted to anus, rectum wound, rectum, sigmoid colon tumor operation, sigmoid colon blocks postoperative and intubate decompression, the expansion of proctostenosis, volvulus of sigmoid resets, the long disease of sigmoid colon, after the congenital megacolon operation, the obstruction of fistula of operative incision etc., because it is low to put the pipe position, can not influence function and other untoward reaction of the heart, lung, kidney.
