With the deepening application of artificial intelligence in the medical field, institutional challenges such as inconsistent data standards, algorithmic bias, and insufficient privacy protection are becoming increasingly prominent. This article systematically reviews the interaction mechanisms between algorithms and ethics in the human-machine symbiosis model of healthcare, analyzes the bioethical conflicts triggered by technology empowerment, and proposes an integrated framework for establishing a new order in intelligent healthcare. By implementing an algorithm-transparent dual-track disclosure system and a three-level dynamic authorization mechanism for sensitive data, the risk of decision-making black boxes is mitigated. Establishing a four-tier model for medical data based on the Data Security Law and creating a three-dimensional supervision mechanism of patient empowerment, ethical firewall, and industry disciplinary measures provide a collaborative governance path to bridge the gap between technological innovation and institutional response.
