Stone removal device for urology

Abstract

The invention relates to a calculus removal device for urinary surgery. The device comprises a sleeve, a basket body and a basket guiding core, the sleeve is internally provided with the basket guiding core, the inner end of the basket guiding core is provided with the basket body, the outer end of the sleeve is provided with a limiting cap, the outer end of the basket guiding core is exposed outside the sleeve and penetrates through the limiting cap, the outer end of the basket guiding core is provided with an operating handle, one end, away from the basket guiding core, of the basket body isprovided with a guiding ball, the inner end of the sleeve is designed as an opening structure, and the sleeve is provided with a conduit near an outer end side wall. In the process of entering an ureter, a syringe injects a dissolving solution into the sleeve to dissolve steinstrasse, the sleeve is expanded into a spindle shape or an elliptical shape, a roller is simultaneously expanded, the sleeve is pulled outward to remove calculus, the conduit is connected with a negative pressure suction device to suck out the calculus brushed to facilitate the absorption of the dissolved and swept calculus, and the steinstrasse in the ureter is effectively removed.

Description

technical field [0001] The invention relates to the technical field of oncology, in particular to a stone removal device for urology. Background technique [0002] At present, in urology, the incidence of kidney and ureteral calculi is increasing year by year. Extracorporeal shock wave lithotripsy has the advantages of less trauma, no need for hospitalization, low cost, and quick recovery. , easy to form a stone street in the ureter, resulting in continuous aggravation of renal colic that is difficult to relieve, aggravation of hydronephrosis, urinary extravasation, gross hematuria and other complications. [0003] The currently commonly used stone removal tools are stone extraction baskets, crushed stone mesh baskets, and stone extraction air bags. The stone extraction mesh baskets are all composed of mesh baskets, sheath tubes, and control handles. The mesh baskets are made of nickel-titanium alloy wire. When encountering sediment-like stones, use the stone removal air ba...

[0003] The currently commonly used stone removal tools are stone extraction baskets, crushed stone mesh baskets, and stone extraction air bags. The stone extraction mesh baskets are all composed of mesh baskets, sheath tubes, and control handles. The mesh baskets are made of nickel-titanium alloy wire. When encountering sediment-like stones, use the stone removal air bag, use the eight-wire basket for soft stones, use the eight-wire basket for small stones ( 1.5cm) with an integrated gravel basket, but not suitable for stone street removal
