Ureteral polyp cutting device for urological departments

Abstract

The invention discloses a ureteral polyp cutting device for urological departments. Through an inflatable airbag limit head, polyp parts can conveniently pass through; and clamping and fixing can be carried out on polyps, so that the normal cutting of the cutting device can be achieved. The cutting device is characterized in that one end of an inner catheter is connected to one end of a syringe; arubber pad is arranged at the connecting part of the inner catheter and the syringe; an airway is arranged inside the inner catheter; a piston rod is sleeved in the syringe and provided with an anti-slip pattern; an outer sleeve sleeves the inner catheter and is close to the other end of the inner catheter; the airbag limit head is arranged on the other end of the inner catheter; and an air cavity is arranged inside the airbag limit head and communicates with the airway. The airbag limit head is provided with multiple through holes at equal angles, so that precise cutting can be performed onpolyp positions; the polyps can be fixed while being cut, so that accurate cutting can be guaranteed, and slipping can be avoided when the polyps are cut; and the cutting device can accurately clamp the cut polyps to pull out, so that the cut polyps can be avoided from falling in ureter.

Description

technical field [0001] The invention relates to a ureter polyp cutter for urology, which relates to a cutter for cutting ureter polyps, and belongs to the field of urology equipment. In particular, it relates to a cutter which facilitates passage of polyps through an inflatable air bag stopper, and can clamp and fix polyps to facilitate normal cutting. Background technique [0002] Polyps refer to the growths on the surface of human tissues. Modern medicine usually refers to the growths on the surface of human mucous membranes as polyps, including hyperplastic, inflammatory, hamartoma, adenoma and other tumors. When there are residual polyps in the ureteroscope, the patient will have ureteral stenosis caused by the polyps on the inner wall of the ureter, which hinders the entry and passage of the inspection laparoscope. Therefore, a device for cutting ureteral polyps is needed. The existing notification number CN209474738U discloses a ureteral polyp cutter, including a lume...
