Description

Percutaneous kidney postoperative hemostasis administration catheter

Technical Field

The utility model relates to the field of medical instruments, in particular to a percutaneous kidney postoperative hemostasis drug delivery catheter.

Background

Percutaneous nephrolithotripsy lithotripsy (PCNL) is becoming the primary therapeutic modality in the clinic in the treatment of urinary stone diseases. PCNL is a minimally invasive urological technique for establishing a fistulization channel from skin to kidney through waist, also called percutaneous kidney channel, by puncturing, expanding and sheathing, then placing nephroscope into renal pelvis and renal calyx, treating broken stone by utilizing ultrasonic and the like and taking out by a stone taking basket, and is a first line treatment scheme for treating the large-load stones on the upper urinary tract with small wound and high stone clearance rate. However, PCNL is post-operatively symptomatic of sustained hematuria, resulting in prolonged patient hospitalization, heavy post-operative pain and increased medical costs. The current clinical post-PCNL hemostatic treatment mode mainly comprises the following steps: compression hemostasis and drug hemostasis. Among them, hemostasis by compression is the most commonly used method, but excessive mechanical compression may give a more pronounced pain sensation to the patient, causing discomfort to the patient. The hemostatic drug is injected into the percutaneous kidney channel, and can diffuse to the surrounding tissues of the channel through loose soft tissues in the percutaneous kidney channel, thereby achieving the hemostatic effect on venous bleeding, but the injection operation requirement on the hemostatic drug in operation is higher, the aim of uniformly distributing the drug on the wound surface and slowly releasing the drug is not achieved, and the hemostatic effect of the hemostatic drug is reduced. At present, the bleeding situation of the wound surface can not be well solved by only one of compression hemostasis or medicine hemostasis.

Chinese patent application entitled catheter for percutaneous renal channel injection of hemostatic, filed under the name CN205586344U, publication date 2016, 09, 21, which discloses the following: the catheter for percutaneous renal channel injection of hemostatic includes double-cavity catheter and air bag, and its front end is equipped with a group of air holes and several groups of medicine-feeding holes in turn, and the air holes are covered by air bag attached on the outside of double-cavity catheter, and the tail end of double-cavity catheter is equipped with medicine-feeding valve port and air-feeding and air-discharging valve port, and the air-feeding and air-discharging valve ports are communicated with air holes by means of air channel pipeline in the double-cavity catheter, and the medicine-feeding valve port is communicated with medicine-feeding hole by means of medicine pipeline in the double-cavity catheter. The scheme has the advantages that the operation steps of injecting the hemostatic medicine into the channel can be simplified, the hemostatic medicine can be uniformly distributed around the channel, the optimal hemostatic effect is achieved, and meanwhile, the related treatment cost is reduced, but the scheme still has the advantages that the medicine which is changed is easy to flow out of the channel and ooze out of the skin, the requirement on the operation of spraying the medicine in the operation is high, the purposes that the medicine is uniformly distributed on a wound surface and the medicine is slowly released are not achieved, and the hemostatic effect of the medicine is reduced.

How to solve the problems is a technical problem to be solved.
