Description

Ureteroscope bladder depressurized system

Technical field

This utility model relates to technical field of medical instruments, specifically, is a kind of ureteroscope bladder depressurized system.

Background technology

Ureteroscopy is the extension of urethroscope cystoscope technology at upper urinary tract, Ureteroscopy refers to by native human's passages such as bladders, per urethra is put into that endoscope carries out ureter and the biopsy of kidney inner tissue, rubble gets stone, to be fulgerized and stricture of ureter such as to cut at the operations, the tract taking full advantage of human body natural carries out some operation techniques, avoids traditional operation and must make a very large otch at abdominal part.Be mainly used in treating lower ureteral calculi, polyp or narrow, also may be used for disease such as diagnosis renal pelvis, tumor of ureter etc.

Ureteroscopy comes out existing over half a century, its advantage is undertaken checking and disease therapy by human body natural's passage, there is the advantages such as Wicresoft's damage is little, few intercurrent disease, determined curative effect, post-operative recovery are fast, extensive in clinical practice, be one of important technology of intracavity Urological Field development.In Ureteroscopy process, in order to ensure to get a clear view in art, perfusion normal saline is needed to maintain surgical field of view.But along with the perfusion continued, urine and infusion liquid are constantly accumulated at intravesical.The excessive bulge of bladder can cause ureteroscope difficulty on show, affects operation technique.Meanwhile, intravesical liquid constantly increases and causes the too high damage that also can cause bladder of intravesical pressure, when serious, even can cause rupture of bladder.Therefore, surgical doctor often needs interrupt operation, exit ureteroscope and catheter drainage urine to alleviate bladder pressure.But repeatedly move back mirror and not only affect procedure efficiency, further increase the risk of urethra, ureter equivalent damage.

Chinese patent literature CN92207065.2, 1992 applyings date December 2 days, patent name is Medical anti-blocking relief pipe, disclose a kind of Medical anti-blocking relief pipe, this Guan Youyi root is soft, dual-hollow conduit is main body, its section is equipped with at least one air bag, fixing capsule, several draught line, several elongated shape side opening, at least one draught line retainer ring and a guide wire, containing air bag gas injection road and gas injection road junction in tube wall (or core), it is characterized in that: the head end of several draught line is fixed on air bag one end, by the draught line retainer ring of the draught line fixing hole on fixation balloon and air bag one end, cross conduit side opening, draught line tail end is fixed in the peritreme of side opening balloon side far away, air bag gas injection road junction is positioned at air bag, guide wire can insert in catheter core.It can prevent the obstruction conduits such as food debris, feces, hematocele, slough, gastrointestinal wall effectively, carries out gastrointestinal, bladder decompression sustainably.But yet there are no report about the bladder depressurized system under Ureteroscopy.

In sum, need a kind of release intravesical liquid badly, alleviate bladder pressure, the ureteroscope bladder depressurized system avoiding injury of bladder even to break.
