Abstract

The invention relates to an auxiliary implantation device for a flexible ureteroscope sheath. The auxiliary implantation device comprises a main body tube and a cap-shaped connecting piece, an annular air bag is arranged on the outer side of the main body tube, a first channel is formed in the main body tube, an air bag catheter is arranged in the first channel, and a first connecting part is arranged at the in-vitro end; the cap-shaped connecting piece is provided with a second connecting part; the cap-shaped connecting piece is provided with a through hole into which the soft lens sheath is inserted; the cap-shaped connecting piece is further provided with an inflation connector. The main body tube is arranged, then the main body tube and the cap-shaped connecting piece are connected, the annular air bag is made to fill the ureter, then the soft lens sheath and the soft lens core are arranged into the first channel through the through hole, the air valve is connected to the inflation connector, the first channel and the interior of the ureter are in a sealed state, and then the air valve is used for inflation; and the flexible sheath and the flexible core are continuously placed into the ureter, and finally, the main body tube and the flexible core can be taken out, so that the placement of the flexible sheath can be completed.

Description

technical field [0001] The invention relates to the technical field of flexible ureteroscope surgical treatment, in particular to a flexible ureteroscope sheath auxiliary insertion device and a use method thereof. Background technique [0002] At present, when a flexible scope or sheath is inserted into the ureter, the inner wall of the ureter is in a state of contraction and collapse. On the one hand, it is not conducive to the insertion of the flexible scope and sheath, and on the other hand, the damage to the inner wall of the ureter by the flexible scope and sheath is aggravated. [0003] The ureter has the characteristic of being fully expanded by liquid and gas without damage from the inside. When ureteral calculi acutely obstructs renal colic, B-ultrasound and CT can see that the ureter is obviously dilated, and this characteristic is intuitively displayed at this time. Based on the above two points, it is necessary and feasible to insert a flexible ureteroscope (shea...
