The utility model relates to the technical field of calculus removing devices. The urological calculus taking device convenient to use comprises an outer sheath tube, an operating rod is arranged in the outer sheath tube in a sleeved mode, two sliding blocks are symmetrically arranged on the outer side wall of the operating rod, a handle is fixedly installed at the right end of the operating rod,a catheter is installed on the right side of the handle, and the catheter penetrates through the handle and the operating rod. According to the utility model, the original stone taking claw is made into the clamping spoon; when the two clamping spoons are used for clamping calculi, the calculi can be clamped; the calculus only needs to be in the range covered by the clamping spoon; the clamping can be directly carried out; the step of calibration and alignment is omitted, time is saved, operation efficiency is improved, meanwhile, the liquid suction head is installed on the left end face of the boss and connected with the air bag through the guide pipe, the air bag is extruded to absorb body fluid generated in the operation through the liquid suction head, the situation that too much bodyfluid covers the calculus is avoided, and the position of the calculus can be found conveniently.
