Medical calculus crushing and removing integrated equipment

Abstract

The invention provides medical calculus crushing and removing integrated equipment. The medical calculus crushing and removing integrated equipment comprises a calculus crushing tube for flexible ureteroscope lithotrity, wherein a negative-pressure chamber for calculus removing is further arranged in the calculus crushing tube, and a primary crushing device comprises a calculus crushing tool I and a gripping tool which are arranged movably; and a secondary crushing device comprises a plurality of calculus crushing tools II which are uniformly distributed on the internal sidewall of the end part of the calculus crushing tube, dilation clamping devices which are used for controlling the calculus crushing tools II to dilate outwards by a distance relative to the inside diameter of the calculus crushing tube are arranged at one end far away from an orifice of the calculus crushing tube, the dilation clamping devices are in a state that the inside diameter of the calculus crushing tube where the calculus crushing tools II are located is dilated when a calculus is clamped by the gripping tool and is abutted against a port of the secondary crushing device, and the calculus crushing tool I is in an operating state. According to the medical calculus crushing and removing integrated equipment, through matching among the primary crushing device, the secondary crushing device and the negative-pressure chamber, the efficiency of calculus crushing and removing is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical integrated equipment for crushing and removing stones. Background technique [0002] A stone suction tube provided by the publication number CN206880712U, the tail section of the suction tube is provided with a number of flushing balloon holes, the outer wall of the suction tube with the flushing balloon holes is provided with a flushing balloon, and the front part of the flushing balloon is An eccentric cone-shaped water sealing cap is provided on the suction tube of the suction tube, and a water injection channel connected to the suction tube is opened on the cap wall of the water sealing cap, and several stone suction holes are opened on the front wall of the suction tube. The above-mentioned stone suction tube is used for removal of residual stones in the renal pelvis after flexible ureteroscopy lithotripsy in urology. On the basis of using the flexible mirr...

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
