Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically be manual negative pressure suction two-chamber double-guide-wire guided flexible ureteroscope guide sheath external member.
Background
The flexible ureteroscope is used with the development of laser energy equipment, a flexible ureteroscope sheath and a 200UM laser fiber, the indications are continuously expanded, the flexible ureteroscope sheath can be used for the stones at the upper section of a ureter with the length of 2cm and even bigger stones, a water outlet channel of the flexible ureteroscope operation is a gap between the flexible ureteroscope and a flexible ureteroscope conveying sheath, the water outlet channel is narrower and longer than a tortuous channel, if the flexible ureteroscope sheath is not placed in place, a system is relatively closed in the operation process, the pressure in a renal pelvis is very easy to increase, if the flexible ureteroscope sheath is infectious stones, the operation time is longer, and uremic sepsis is easy to occur, so the key technology in the flexible ureteroscope operation is that the flexible ureteroscope sheath must be placed in place, the optimal position is at the junction of the renal pelvis ureter, if the water outlet is placed in place, the water outlet is more smooth, generally, before the flexible ureteroscope sheath is placed, F8/9.8 ureter hard ureter is used for exploring the thickness of the flexible ureter, to decide whether the first or second stage ureter soft lens operation.
The defects of the prior art are as follows:
at present, most hospitals and most patients adopt primary ureteroscope operation, and the soft scope operation generally adopts a thicker guide wire of 0.35/150 or 0.38/150, so that the guide wire is not easy to bend during the advancing process of the ureteroscope delivery sheath, the ureteroscope delivery sheath is not placed in place, but when patients with severe ureteroscope tortuosity, a single guide wire is used for guiding the placement of the ureteroscope sheath to be not easy to place, even the guide wire is inserted into the sheath during the placement process occasionally, the guide wire is used for bending the ureteroscope to perforate, and when the patients with the ureteroscope tortuosity use a double-guide-wire implantation guide in clinic, the flexible ureteroscope can be straightened, so that one guide wire is used as a guide outside the ureteroscope sheath, and one guide wire is guided by the ureteroscope sheath, the placement of the ureteroscope delivery sheath to the ideal position at the renal pelvis junction can be improved, but because one guide wire is guided outside the ureteroscope sheath, the improved Y-shaped flexible ureteroscope delivery sheath with negative pressure suction has been developed and marketed for a long time, and a double-cavity improved Y-shaped flexible ureteroscope delivery sheath with negative pressure suction is provided, but the outer diameter of the double-cavity improved Y-shaped flexible ureteroscope delivery sheath is 16F due to the addition of a channel, so most of operation patients using the flexible ureteroscope delivery sheath need to pre-place a ureteral stent for 15 days to 30 days to expand a ureter and then carry out secondary flexible ureteroscope operation. The original intention of the minimally invasive surgery is lost. Therefore, the single-cavity manual control negative pressure suction Y-shaped flexible ureteroscope conveying sheath has low practical value, small calculus blocks are sucked into a water outlet channel between a flexible ureteroscope and the flexible ureteroscope conveying sheath by using negative pressure suction in an operation, and small broken calculus is irregular, so that the outer-layer foreskin of the flexible ureteroscope is easily damaged when the flexible ureteroscope enters and exits the flexible ureteroscope conveying sheath, the air leakage, water inlet, damage and poor visual field of the flexible ureteroscope are caused, and the flexible ureteroscope conveying sheath has use superiority before the use of a disposable flexible ureteroscope and is not high in clinical use enthusiasm.
