A medical stone crushing and stone removal integrated equipment

Abstract

The present invention provides a kind of integrated equipment for medical stone crushing and stone removal, which includes a stone crushing tube for flexible ureteroscopic lithotripsy. The stone crushing tube is also provided with a negative pressure chamber for stone removal. The primary crushing device includes a movable The stone crushing tool I and the grabbing tool are set; the secondary crushing device includes a number of stone crushing tools II evenly distributed on the inner wall of the end of the stone crushing tube, and a control device is installed at the end of the stone crushing tube away from the mouth. The expansion fixture of the expansion distance of the lithotripsy tool II relative to the inner diameter of the stone crushing tube, when the grabbing tool holds the stone against the port of the secondary crushing device, the expansion fixture is in the position where the lithotripsy tool II is located The state of the inner diameter of the stone crushing tube, and the stone crushing tool I is in working state. The present invention improves the efficiency of crushing and discharging stones through the cooperation of the primary crushing device, the secondary crushing device and the negative pressure chamber.

AI Technical Summary

Problems solved by technology

The above-mentioned stone suction tube is used for removal of residual stones in the renal pelvis after soft ureteroscope lithotripsy in urology. On the basis of using the soft mirror sheath, the crushed stones can be sucked out of the body during the operation. However, the stone removal efficiency of the device is Not high, the lithotripsy process has a risk of damage to the human body, and in the process of stone removal, the finer stone residues cannot be discharged well, and patients still need to continue stone removal treatment after surgery, and there is a risk of stone recurrence
