The invention relates to a pressure regulator for a urinary incontinence operation. The pressure regulator for the urinary incontinence operation comprises an obtuse apparatus, a baroreceptor, transmission lines, a controller and a pressure display unit, wherein the obtuse apparatus comprises a supporting portion, a connecting portion and a handle portion; the baroreceptor is connected to an input end of the controller by virtue of the transmission line; an output end of the controller is connected to the pressure display unit by virtue of the transmission line; and the baroreceptor comprises a shell, a pressure concentrating film, a pressure transmission medium, a semiconductor strain gauge and a conversion element. The pressure regulator for the urinary incontinence operation provided by the invention has the advantages that the pressure regulator is specially applicable to an operating step of regulating the elasticity of a suspension strap and drawing out a thin film, and the action force of resisting the suspension strap when the thin film is drawn out can be intuitively displayed so as to guide doctors to regulate the elasticity of the suspension strap in the operation; and in addition, tension, generated from the placed suspension strap, on a urethral canal can be prevented, so that precise individual treatment is achieved.
