The operating equipment for the treatment of.
Background technology
Urinary tract is the toxin expelling system of human body, there are numerous toxin and sediment in urine, and urine is by kidney mistake
Filter enters urinary tract, and in this metabolic processes, kidney and urinary tract often form sediment, and the time causes kidney and urine for a long time
Road calculus.In the removal kidney stone operation of urological department, rubble, rubble are carried out using a kind of uropoiesis endoscope-assistant surgery device such as Fig. 1
The method that vacuum suction must be rinsed with convection current afterwards removes rubble, and the pressure in operation in renal plevis must not be higher than 40 centimeter water column pressures
Power just can guarantee that the life security of rubble patient, and whole surgical procedure is that rubble --- convection current flushing --- negative pressure absorbs process
Constantly repeat.This operation method can the safe most important whether have and continue definite effective vacuum suction.In operation
The drawing liquid channel outlet of the mixed liquor such as rubble powder, blood clot, purulence tongue from uropoiesis endoscope-assistant surgery device is entered by connecting tube in renal plevis
The drainage bottle for being connected with negative pressure ventilation mouthful is entered back into after entering the separation of rubble collecting filter.
Existing rubble collecting filter cavity is by the upper cavity provided with inlet and the lower chamber screw thread provided with liquid outlet connects
Composition is connect, the filter screen for being used for filtering rubble is provided with cavity.Had the disadvantage that using this rubble filter collector：From secreting
Corporeal thing in the mixed liquor of the drawing liquid passage outflow of urine endoscope-assistant surgery device is easy to adhere to each other heap at filter screen, easily makes
Stifled into stalk, operating time is more long more obvious, and can not immediate observation judge, cause negative pressure unstable, influence continuous and effective it is negative
Pressure attracts, so as to influence the progress of operation, to increase operation risk.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of convection current negative pressure channel rubble suction filter device, and it can be solved
