Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of negative pressure adjusting device be connected with ureter sheath.
Background technology
Along with growth in the living standard, people's diet structure is also occurring to change, and the patient of upper urinary stone increases year by year, with renal calculus patient is wherein very especially.The operative treatment mode of current main flow has gets the non-natural passage rubble such as stone and percutaneous kidney fistulation through natural passage (i.e. urethra, bladder, ureter) as operation pathway rubble and gets stone, there is the complication such as massive hemorrhage, renal function destruction and damaging surrounding tissue organ owing to getting stone through non-natural passage rubble, medical circle is praised highly gradually and is carried out renal calculus operation using natural passage (i.e. urethra, bladder, ureter) as operation pathway in recent years.
When carrying out renal calculus operation through natural passage, need in art through natural passage indwelling ureter sheath as operation path, so that ureteroscope can pass in and out kidney fast through ureter sheath and perform the operation, avoid repeatedly passing in and out causing damage to ureter, can operating time be shortened simultaneously, improve the safety of operation.Insert through ureter sheath ureteroscope Bladder stone carry out renal calculus rubble operation time, constantly flushing liquor need be poured through ureteroscope, to keep getting a clear view, , constantly pour into the flushing liquor in kidney aggregation system, the kidney aggregation system pressure making volume less increases, and as the finite gap between the ureteroscope of drainage channel and ureter sheath, and pipeline is longer, self-draining effect is poor, be easy in operation process cause kidney aggregation system high pressure, kidney is caused damage, especially for renal calculus concurrent infection patient, also there will be the situation that antibacterial and toxin enter blood circulation, cause urine source sexuality dye, patient's life may be jeopardized time serious, on the other hand, the calculus powder produced in lasertripsy and disintegrating slag can affect surgical field of view, need repeatedly to take out calculus disintegrating slag with calculus catching net-like means or lithotomy forceps, so just have impact on procedure efficiency, operating time are extended, adds operation risk.
In view of the foregoing, mention in " urological diseases diagnoses and treatment guide ": be domesticly not recommended for as process is greater than the first-selected Therapeutic Method of 2cm calculus through natural passage as operation pathway treatment renal calculus; This means, more than the calculus of 2cm, be not suitable for adopting this operation method.But nonetheless, operation is taken out for the renal calculus being no more than 2cm, adopts this operation method to be still easy to the situation occurring that kidney aggregation system pressure is high, cause urine source property infection rate high, affect carrying out of this modus operandi.
Therefore, effectively can control the internal pressure of kidney aggregation system, particularly important as the safety of operation pathway treatment renal calculus operation for improving through natural passage, and to the clear visual field can be provided in Rhizoma Atractylodis Macrocephalae and effectively remove calculus powder disintegrating slag fast, to ensure that operation completes fast and ensures that surgical effect is all significant.
