Document Type and Number:
WIPO Patent Application WO/2022/242450
Kind Code:
A1
Abstract:
A push rod assembly and a medical device. The medical device comprises the push rod assembly and a medical implant. The push rod assembly comprises: a push rod (100), having a first inner cavity; a position-limiting mechanism (200), comprising a first sub position-limiting mechanism (210) and a second sub position-limiting mechanism (220), the first sub position-limiting mechanism (210) being provided at the proximal end of the medical implant, having a first position-limiting area (211) formed thereon, and comprising a first blocking portion (212), the first blocking portion (212) being provided at the proximal end of the first position-limiting area (211), a first through hole (213) being formed in the first blocking portion (212), and the second sub position-limiting mechanism (220) being connected to the distal end of the push rod (100); and a control rod (300), when the distal end of the control rod (300) passes through the first inner cavity and the first through hole (213) and the distal portion of the second sub position-limiting mechanism (220) is limited within the first position-limiting area (211), the push rod assembly being in a locked position, and when the control rod (300) moves along the axial direction of the first through hole (213) to allow the distal portion of the second sub position-limiting mechanism (220) to be separated from the first position-limiting area (211), the push rod assembly being in an unlocked position. When the push rod assembly is used to push a medical implant, the precision of positioning for the medical implant can be improved.
