Sleeve connection type urethral valve resection device

A urethral valve resection device is integrally in a slender rod shape and is composed of a tail portion, a slender body portion and a head portion thicker than the body portion, and cutting bodies distributed circumferentially are arranged on the inner portion of the lower portion of the edge portion of the head portion. During use, the head is inserted from an external urethral orifice and pushed towards an internal urethral orifice, when the head is in contact with a urethral valve, obvious resistance is generated, the head is pushed forwards forcibly to break through an intervalvular fracture, and then the head is pulled backwards forcibly, so that the root of the tightened urethral valve is cut and broken by the cutting edge of the cutting body; the head brings the cut urethral valve out of the urethra. 一种尿道瓣膜切除装置，整体呈细长杆状，由尾部、细长的体部和比体部粗大的头部组成，头部边缘部分下方靠内部分设有环周分布的切割体；使用时，先使头部从尿道外口插入并向尿道内口方向推进，当头部接触到尿道瓣膜时会有明显阻力，用力继续向前推动使其头部突破瓣膜间裂隙，随即用力向后拉动，使切割体的切割缘将紧绷的尿道瓣膜根部切割断裂，头部将切除的尿道瓣膜从尿道带出。
