Technical field
This utility model belongs to technical field of medical instruments, is specifically related to micro-wound percutaneous kidney mirror with expansion hemostasis fistulation pipe.
Background technology
PCN is the efficacious therapy method of the minimally-invasive treatment renal calculus of development in recent years, and it has, and therapeutic effect is good, the calculus clearance rate high, renal function injury is little, go out insufficiency of blood and the little characteristics of wound.PCN one or more passages that need in renal cortex, puncture undergo surgery, and after operation finished, kidney fistulation pipe played the effect of drainage of urine and hemostasis by compression.
Yet,, thereby between kidney puncture channel and kidney fistulation pipe, have certain gap because of the diameter of kidney fistulation pipe must just can be inserted in the kidney less than the diameter of puncture channel; The effect of kidney fistulation pipe hemostasis by compression is limited; Few part patient can form serious hemorrhage, for the hemorrhage patient that comparatively seriously can't use the control of internal medicine means, even need carry out the hemostasis of selective embolization art or the nephrectomy; Not only expense is higher, but also can cause a part or all irreversible forfeitures of renal function; In addition; Traditional fistulation pipe is generally the latex tubing of not being with air bag, and it can't be fixed voluntarily, and histocompatibility is relatively poor; Partial inflammatory reaction is more serious; The infection rate of following is higher, is not suitable for carrying for a long time, and the patient who especially need carry out second phase and above operation for the part patient makes troubles and be painful.
For this reason; Someone improves with the fistulation pipe traditional micro-wound percutaneous kidney mirror; Like the CN201585959U patent that Patent Office of the People's Republic of China announces on JIUYUE 22nd, 2010 in the CN201052137Y patent of on April 30th, 2008 bulletin and Patent Office of the People's Republic of China, both mentalities of designing have similarity, and promptly the fistulation pipe comprises drainage tube, is positioned at the drain side opening of drainage tube head and is positioned at the drainage tube joint of drainage tube afterbody; Behind drainage tube head, drain side opening, be provided with an air bag; It is communicated with an aerating pipe, and aerating pipe stretches out along drainage tube tube wall to drainage tube afterbody, and the former utilizes aerating pipe to give the air bag water filling; The The latter aerating pipe is given airbag aeration, thereby realizes hemostasis by compression.Though both have all simplified operation process, be convenient to operation; Reduce the probability of postoperative blood transfusion and super-selective tremulous pulse pivot plug, adopted silica gel material to process, had the favorable tissue compatibility; Can remain in for a long time in patient's body, no obvious toxic and side effects is convenient to the patient and is further treated; But air bag water filling or inflation are not easy to realize, and can make patient that uncomfortable distending pain sense is arranged; Continue water filling or inflation after the inside and outside pressure balance of air bag again and then can only overflow and can't continue supercharging, thereby do not reach ideal haemostatic effect.In addition, both all are not provided for the fixedly structure of fistulation pipe specially, and this makes the fistulation pipe be easy to slippage displacement, less stable.
