Abstract

The invention provides a continuous negative-pressure suction apparatus for ureteroscopic holmium laser lithotripsy use. The continuous negative-pressure suction apparatus for ureteroscopic holmium laser lithotripsy use comprises a three-way infusion device, a liquid suction hose, a ureteral catheter, a first sealing cap, and a second sealing cap; one end of the three-way infusion device is sleeved with the liquid suction hose; the ureteral catheter is fixedly mounted at one end of the three-way infusion device, and communicates with the three-way infusion device; and a junction of the three-way infusion device and the ureteral catheter is sleeved with the first sealing cap. The continuous negative-pressure suction apparatus for ureteroscopic holmium laser lithotripsy use provided by the invention has the advantages of being low in cost, convenient to use, and capable of maintaining good field of view, improving lithotripsy efficiency, shortening operation time, preventing stone from moving up, increasing stone clearance rate, reducing renal pelvis pressure, reducing risk of infection, decreasing possibility of falling of the liquid suction hose due to pulling of the liquid suctionhose, ensuring smooth conduction of the operation and the like.

Description

technical field

[0001] The invention relates to the field of medical technology, in particular to a continuous negative pressure suction device for ureteroscopic holmium laser lithotripsy. Background technique

[0002] Ureteroscopic holmium laser lithotripsy is the first-line treatment for ureteral calculi because of its definite effect, quick recovery and few complications. The movement of stones to the kidney during the operation is one of the main reasons for the failure of ureteroscopic holmium laser lithotripsy, and it is also an important hidden danger of medical disputes. It has been reported in the literature that the incidence of calculi moving up during ureteroscopic holmium laser lithotripsy for lower ureteral stones is 3% to 15%, while the incidence of upper ureteral stones is as high as 28% to 48%. The upward movement of the stones leads to the failure of the operation or changes to the operation method, such as soft mirror lithotripsy or percutaneous nephrosco...
