Domain.
Background technique
Percutaneous nephrolithy is clinically to handle the conventional means of staghorn stone of kidney and kidney calices or calculus in diverticulum, and patient is first
Through the small of the back skin establish puncture channel under B ultrasound or x-ray guidance, it is then stretched after channel be placed in percutaneous nephrolithy, use
The technologies such as ultrasound, laser carry out rubble, and the patient of the above ponding of moderate, percutaneous nephrolithy operation are merged for solitary pyelolithiasis
Have many advantages, such as that wound is small, the time is short, lithotrity effect is good, but in the calculus for handling parallel small cup calculus or other dead angle positions
When, since the viewing directional angle of traditional hard scape camera end is generally 12 degree, visual range is limited, and it may cause and find calculus difficulty, and
And instrument channel is integrated with aquaporin, even if calculus is in visual range, due to laser fiber can not bendable, still without
Method, which aims at, carries out rubble, if changing by force into mirror angle or increasing puncture channel, will lead to the damage of renal tissue, and prolong
Long operating time increases the probability of the complication such as channel bleeding.Percutaneous nephrolithy joint Flexible ureteroscope is current processing complexity
The effective means of calculus, but due to the limitation of Flexible ureteroscope bending radius, it is narrow for part lower calyx calculus and small cup neck
Patient, lithotrity effect is still undesirable, and artificially increases operating time and operating difficulty.
Chinese patent document (publication number CN103622661A) discloses a kind of hard percutaneous nephrolithy of bendable front end, preceding
End is designed as curved instrument channel, and the kidney lens device in the program is when being performed the operation, because of the curved shank design in front end
Can have bending radius, this will the additional operation difficulty for increasing operation, in percutaneous nephrolithy operation especially uronephrosis it is unobvious,
When small cup neck is narrow and impracticable, the anatomical structure complexity of kidney aggregation system determines that straight line mirror body is only percutaneous nephrolithy
The optimal selection of operation, but there are still aforementioned many deficiencies for straight line mirror body.
Summary of the invention
