Urinary guiding device used in urinary surgery

Abstract

The invention relates to the technical field of medical instruments, and discloses a urinary guiding device used in urinary surgery. The urinary guiding device comprises a guide tube, the upper end surface of the guide tube is a convex surface, a round hole is formed in the middle of the convex surface, and a pushing device used for pushing the upper end of the guide tube to move forward is detachably arranged in the guide tube; the pushing device comprises a pushing tube and a lubricating oil injection device, the pushing tube is a flexible metal tube, and the pushing tube is detachably arranged in the guide tube; a spherical convex surface is arranged at the front end of the pushing tube, a plurality of second through holes are formed in the spherical convex surface, the spherical convexsurface penetrates through the round hole and protrudes out of the guide tube, and the lower portion of the pushing tube is detachably connected with the lubricating oil injection device; and a tubeconnector is detachably connected with the lower end of the guide tube and detachably connected with a urine collecting bag through a pipeline. According to the urethral guiding device used in the urinary surgery, the advancing resistance of the guide tube is reduced, the discomfort of a patient when the guide tube is inserted is relieved, thrust can be transmitted to the front end of the guide tube easily, then the guide tube can reach the bladder smoothly, and smooth performance of the surgery is secured.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a urinary catheter used in urological operations. Background technique [0002] Before or during urological surgery on urological patients, it is necessary to use a catheterization device to communicate with the patient's bladder for catheterization. However, when the existing catheterization device enters the human body, especially when it encounters a bend, The front end cannot change direction automatically, it can only rely on thrust from the rear end. [0003] However, the existing urinary catheter is a soft tube, and the thrust is difficult to transmit to the front end, and the front end is constantly rubbing against the urethra of the human body, so the forward resistance is relatively large, and it cannot reach the bladder smoothly, which brings pain and discomfort to the patient or prolongs the operation time. surgical risk.
