Abstract

The invention belongs to the technical field of urinary surgery, and particularly relates to a urethral dilator for urologic surgical procedures and a control method. The dilator comprises a support frame and a dilating main body, wherein a control rod is clamped and connected to one side in the support frame, a guide gas bag body is bonded to the tail end of one side of the outer surface of the control rod, a rubber hose is integrally formed on one side of the outer surface of the guide gas bag body, a clamping rod is bonded to one side of the outer surface of the guide gas bag body, one sideof the outer surface of the clamping rod is clamped to one side of the interior of the dilating main body, and a positioning pin penetrates through positioning holes formed in a first pushing pistonand a second supporting block, so that the first pushing piston can be ensured to be stable, then the gas amount in the guide gas bag body is ensured to be stable, the stable supporting performance ofthe guide gas bag body is ensured, and the guide gas bag body can better enter a urethra for guiding; and by pulling the control rod in the support frame and the dilating main body, the guide gas bagbody can be driven to move, and a guide angle of the guide gas bag body can be adjusted to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of urology, and in particular relates to a urethral dilator for urology and a control method. Background technique [0002] Urology is a hospital department that mainly diagnoses and treats some diseases of the "surgery" of the urinary system, and mainly treats various urinary diseases. In urological surgery, urethral dilators are often used to treat urethral strictures. The existing urethral dilators are generally composed of a solid metal cylinder. It may be different. When the urethral dilator is directly inserted into the urethra, it will not only increase the pain of the patient, but also may cause the patient's urethral bleeding to a large extent. At the same time, the existing urethral dilator lacks certain practicability and cannot be used efficiently. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a urethral dilat...
