Background technology
Urinary system calculus is one of common disease of Urology Surgery.Along with the universal development of chamber endoscopic technic and being rooted in the hearts of the people of Wicresoft's theory, Flexible ureteroscope technology has become Urology Surgery very important Clinics and Practices means clinically at present, intracavity rubble under Flexible ureteroscope is line main flow means for the treatment of upper urinary stone at present, have Wicresoft, safety, painful little, recover fast, can look at the lower observation also advantage such as rubble.Flexible ureteroscope operation needs the guiding transfer passage using Flexible ureteroscope sheath as turnover human body urinary system in practical operation.
The Flexible ureteroscope sheath of current Clinical practice does not possess the clear stone function of vacuum suction, this makes current Flexible ureteroscope operation calculus can only be broken into Microlithiasis, and calculus can not be attracted out, cause in patient body and leave a large amount of Microlithiasis, the urine that Post operation need rely on patient self to secrete is rinsed and is excreted by calculi in vivo.But this lithagogue method may cause when calculus is discharged ureteral friction and damage, produce the pain in urine output area under control, inflammation, infection, narrow or form stone street (the stone street microlith smashed of namely being performed the operation has lined up team in elongated ureter, just as the road that stone is paved into, therefore named stone street), severe patient also need second operation.
Meanwhile, the Flexible ureteroscope sheath of current Clinical practice does not possess the ability measuring pressure, and in Flexible ureteroscope operation, in patient's urinary system, the pressure especially in ureter and renal pelvis can raise.High pressure both may the urinary system of injured patient, and the antibacterial in urinary system or calculus also may be made to enter blood at the effect retrograde of high pressure, and producing strains mass formed by blood stasis, pyaemia septica etc., make patient occur septic shock, threat to life.
Summary of the invention
The present utility model provides a kind of Flexible ureteroscope sheath connecing vacuum suction and pressure gauge, mainly solves the problem that existing ureteroscope sheath can not attract to remove calculus and can not measure pressure.The present utility model can connect negative pressure suction device, to attract to remove in patient urinary system by the Microlithiasis smashed of performing the operation, and reduces postoperative dependence Urine in Patients and washes away such as pain that calculus causes, inflammation, infection, narrow or form the complication such as stone street.Meanwhile, the present utility model also can in operation Bonding pressure measuring device, measure the pressure in the urinary system such as ureter and renal pelvis, the urinary system injury avoiding hypertonia to cause and antibacterial enter the septic shock after blood.
This utility model solves the technical scheme that its technical problem adopts: be made up of the epitheca of hollow and the hollow conduit that is nested into epitheca, thus whole Flexible ureteroscope sheath inside be divided into two parts: i.e. Flexible ureteroscope passage and attract measuring pressure passage.Flexible ureteroscope passage, as the transfer passage guiding Flexible ureteroscope turnover patient urinary system, attracts measuring pressure passage remove calculus as vacuum suction and measure the passage of pressure.
After adopting technique scheme, its feature is: (1) changes the single-pass configuration of existing Flexible ureteroscope sheath inside, solves the present situation that prior art can not attract to remove calculus.The present utility model can realize utilizing negative pressure suction device to attract to remove calculus in operation.Decreasing postoperative patient relies on urine to wash away calculus removing misery and related complication, reduces the probability of second operation, makes patients benefit.(2) the present utility model can play fixation to calculus in art.In operation, have some calculus may be moved in doctor's operating process, circular calculus, just as " Semen Glycines in bowl, chopsticks run at a touch ", is unfavorable for that operation is carried out like this, and may produces Accessory injury.The present utility model utilizes vacuum suction the calculus of movement can be attracted to be fixed on the collar extension of Flexible ureteroscope sheath, by the change of vacuum magnitude, can control the dynamics that calculus is attracted.So, the calculus of movement is become fixing calculus, facilitate doctor to carry out operation rubble.(3) the present utility model changes the present situation cannot measuring pressure in the urinary system such as ureter and renal pelvis in the operation of existing Flexible ureteroscope, the measurement of pressure in can realizing performing the operation, the septic shock avoiding the urinary system injury because hypertonia produces and antibacterial to enter blood causing.
With prior art ratio, the beneficial effects of the utility model are: make Flexible ureteroscope sheath can connect vacuum suction and pressure gauge, add and attract clear stone and tonometric function, improve surgical effect and safety, decrease the possibility of the misery of patient, the generation of complication and second operation.
