Technical field
The device attracted is rinsed for visual area in calculi in urinary system lithotrity the utility model relates to a kind of.
Background technique
Lithangiuria is a kind of common urological diseases, and often hair is in ureter and bladder.In recent years, with minimally invasive outer
The development of section's technology has become the mainstream technology of Current therapeutic urinary calculus using minimal invasive operation lithangiuria, wherein defeated
Urinary catheter mirror rubble, percutaneous nephroscope lithotripsy are the methods of two kinds of important minimally-invasive treatment calculus.
In existing technical solution, ureteroscope lithotrity is to be inserted into a ureteroscope by urethra, bladder
In ureter, then ureteral calculi or kidney stone is smashed by various auxiliary instruments, (punching) is taken to go out.It utilizes human body natural
Urinary system cavity, do not do any notch physically, be a kind of pure Urology Surgery hysteroscope Minimally Invasive Surgery.Suitable for protecting
Keep the invalid various ureteral calculis for the treatment of and part kidney stone.Compared with open surgery, ureteroscope lithotrity has damage
Hurt the advantages that small, painful light, recovery is fast.But that there is surgical field of view in actual surgical procedure is unclear for ureteroscope lithotrity
The problem of clear and thermal damage, will cause procedure efficiency reduction, surgical quality reduces, operation wind since the visual field of operation is unintelligible
Danger increases, and in lasertripsy, local heat effect is obvious, will lead to the damage for leading to mucous membrane of ureter.It generallys use at present
Be from the channel of ureteroscope to operative region be perfused physiological saline (be in ureteral calculi lithotrity from the outside to the core, from it is lower to
On, it is from up to down in pyelolithiasis lithotrity), but such processing still has problem, including the visual field still may not be
Very clear, Renal pelvic pressure increases and with the complication such as infection caused by this.It is next it is therefore necessary to design a kind of new equipment
Preferably meet the actual needs.
