Title:
RESECTOSCOPE SEALING MEMBER
Document Type and Number:
WIPO Patent Application WO/2022/012301
Kind Code:
A1
Abstract:
A resectoscope sealing member (10, 20) comprises a first end surface (11, 21), an outer circumferential surface (12, 22), and a second end surface (13, 23) sequentially connected. The first end surface (11, 21) and the second end surface (13, 23) are disposed oppositely. The outer circumferential surface (12, 22) can be sealedly connected to an inner peripheral wall surface of an inner sheath (31) of the resectoscope. The resectoscope sealing member (10, 20) further comprises a positioning portion (14, 24). The positioning portion (14, 24) protrudes outward from or is recessed inward at the first end surface (11, 21), and can be fitted and connected to a resectoscope handle (32). This resectoscope sealing member (10, 20) overcomes the technical drawbacks of the prior art. The resectoscope sealing member (10, 20) is installed in a resectoscope (30), has material uniformity, and does not have any internal gaps, and the outer circumferential surface (12, 22) thereof is sealedly connected to the inner peripheral wall surface of the inner sheath (31) of the resectoscope, thereby providing a superior sealing performance and ensuring a sealing effect. In addition, the positioning portion (14, 24) provided on the resectoscope sealing member (10, 20) achieves positioning of the resectoscope sealing member (10, 20) in a circumferential direction, thereby preventing the sealing performance being affected by a rotation thereof, and achieving an optimal sealing effect.
