Disposable atraumatic urethral dilator and method of use thereof

Abstract

The invention is applicable to the field of medical apparatuses and discloses a disposable injury-free urethral dilator and a using method thereof. The disposable injury-free urethral dilator comprises a tearable sheath tube with a round or oval cross section and a sheath rod movably inserted in the sheath tube, the sheath tube is provided with a smooth surface, an extension end and a tear end, a tearing structure used for guiding the sheath tube to be torn is arranged on the outer surface of the sheath tube and linearly extends to the extension rod from the tear end, the tip of the extension end is provided with a through hole allowing a resectoscope to penetrate out, a central axis of the through hole and a central axis of the sheath tube are located on the same straight line, and the sheath rod is provided with a sealing portion which penetrates out of the through hole and is used for closing the through hole. The disposable injury-free urethral dilator can provide guidance for insertion of the resectoscope, the urethra is protected, pain of patients is reduced, and postoperative recovery of the patients is facilitated; the using method is simple in step and easy to operate, and surgical efficiency is improved.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a disposable urethral non-injury dilator and a use method thereof. Background technique [0002] Prostatic hypertrophy and hyperplasia are common diseases with a high incidence in middle-aged and elderly men, and surgical resection is the most effective treatment. Existing treatment methods all adopt resectoscope to carry out resection operation, and its postoperative trauma area is small. However, when a resectoscope is used for surgery, the existing method is to insert it directly from the male urethra, and because the width of the urethra is small, it is difficult to insert the resectoscope, and the forced insertion method is also difficult. It will cause greater damage to the urethra, increasing the pain of the patient and the difficulty of postoperative recovery. At the same time, the operation of inserting the resectoscope takes a long time, which increases the ...
