Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of kidney stone therapeutic equipment and be controlled with kidney stone
Treat the molten method except kidney stone of equipment.
Background technique
Calculi in urinary system is summarized: calculi in urinary system is more common in any position of kidney, ureter, bladder and urethra, with
Kidney is relatively conventional with ureteral calculi.Lithiasis is easier to recur, and 1 year recurrence rate of calcium oxalate kidney stone is 10%, 5 according to statistics
Year, recurrence rate was 35%, and 10 years recurrence rates are 50%.
Kidney stone falls into ureter, and causes ureteral obstruction and colic pain occurs.About due to ureter relatively narrower
(wherein renal plevis and urine output pipe jointing part, bladder and urine output pipe jointing part be about), size existsIt ties below
Stone, when exclusion painless, accessible sense, is largely less thanCalculus symptom occur 1 month after can be automatically drained out, and
It is greater thanCalculus can not be automatically drained out, be greater thanCalculus there is more than half not to be automatically drained out.
Naturally stone or drug row's stone are arranged, row's stone purpose, extracorporeal shock wave lithotripsy and operation is extremely difficult to compared with maximum size to volume
Stone is taken, therapeutic effect is bad, and the period is long, and wound is larger.
Medical worker is when treating kidney stone patient, in medical level at this stage, mostly uses body
Then the method for outer rubble is excreted by patient from being about to intracorporal rubble, but due to external stone crushing when is mostly direct
By calculus by falling off on kidney, calculus block may be bigger, is easy blocking patient's urethra, brings pain to patient, therefore cannot be very
The good a variety of exclusive requirements when treating to kidney stone patient at this stage that meet if things go on like this considerably increase medical matters
The work difficulty of personnel.
Utility model content
The purpose of this utility model is that overcome defect existing in the prior art, provide a kind of structure it is simple, using just
Victory, therapeutic effect are good, will be explained and are dissolved using solvent, and solvent is set by the kidney stone treatment of one of the utility model aim
It is standby import two of calculus lesions position and the purpose of this utility model in kidney kidney stone is dissolved by solvent after, pass through urethra
Excrete the molten method except kidney stone.
To achieve the above object, the technical solution of the utility model first is that design a kind of kidney stone therapeutic equipment, it is described
Kidney stone therapeutic equipment includes instillator, and drip tube is equipped in instillator, and the front tube wall of drip tube is equipped with instillation hole, instils
