Description

Flexible electronic ureteroscope with bendable lens-sheath integrated head end and negative pressure suction type

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an electronic ureteroscope with a bendable lens-sheath integrated head end and negative pressure suction type.

Background

Along with the continuous development of medical technology, the ureteral soft lens technology is increasingly applied to the minimally invasive treatment of urinary calculi, and the electronic ureteral soft lens is a slim and bendable endoscope, has the characteristics of easy lens holding, light and handy operation, clear visual field and the like, can enter the kidney through the natural cavities of the human body such as the urethra, the bladder, the ureter and the like, is matched with holmium laser and the like to crush the urinary calculi in the human body, and is mainly suitable for treating kidney calculi below 2 cm and calculi at the upper section of the ureter.

Before the electronic ureteroscope is used, the electronic ureteroscope needs to be placed on a guide wire and then placed on a sheath tube of the electronic ureteroscope through the guide wire; and then, after the guide wire is taken out, a channel for the electronic ureteroscope to enter is built in the sheath.

However, in the holmium laser lithotripter process of the electronic ureter soft lens, the generated calculus dust and bubbles easily cause blurred vision, and the traditional flushing method relies on flushing liquid to flow out at a constant speed through the head end of the electronic ureter soft lens, flows out from a gap between the sheath tube and the electronic ureter soft lens and is sucked and discharged through negative pressure. However, the gap between the sheath tube and the electronic ureteroscope is smaller, and the calculus fragments are easy to be blocked in the gap, so that the calculus is not perfectly discharged. Meanwhile, when the sheath tube and the electronic ureteroscope are combined, the head end of the sheath tube needs to be passively bent by the electronic ureteroscope, so that a plurality of renal calyx in the kidney cannot be freely moved in and out, and the effect of negative pressure suction on broken stone is not ideal.
