## Abstract

A novel rotary and telescopic sperm extractor is disclosed. The sperm extractor includes a telescopic mechanism; a rotary mechanism mounted on the telescopic mechanism; and an inner container mounted on the rotary mechanism, where the rotary mechanism rotates while making a reciprocating telescopic motion along with the telescopic mechanism. The rotary mechanism includes a second motor which drives a second gear that has a hollow structure. A rotary conductive slip ring is arranged within the hollow structure to stably transmit electrical power during continuous rotation of the gear. The inner container is replaceable, and its tail end is provided with a circuit board equipped with metal contacts. This circuit board interfaces with elastic metal columns on the rotating component to achieve power supply and identification. This design addresses the technical challenge of providing stable power and data communication to a replaceable inner container undergoing simultaneous rotary and telescopic motion.
