The invention discloses a hemostatic clamp opened by spring force and provided with a degradation structure, belongs to the technical field of medical hemostatic equipment, and relates to a hemostatic clamp which is used under an endoscope, provided with a degradation structure and opened by spring force. The hemostatic clamp is composed of a clamp part and an operation part. The clamp part is composed of a clamp tube, an elastic piece, a positioning pin, a clamping piece, a sliding wheel, a spring, a connecting pin, a clamping piece fixing seat, a mandrel and a connecting tube; and the operating part of the hemostatic clamp is composed of a spring hose, a connecting pin, a rotating ring, a rotating ring fixing seat and a hook. The hemostatic clamp is simple and ingenious in structural design and convenient and flexible to operate. A polylactic acid degradable material is adopted, a protruding degradable hanging block is installed on the elastic piece at the bottom of the clamping piece, and the falling-off time of the clamping piece is controlled through the degradable structure. A spring and a roller on the positioning pin are used for controlling the opening of the clamping piece and discharging the clamping piece out of the body along with body fluid. By designing the degradable structure, the loosening time of the clamping piece of the hemostatic clamp is controlled, and secondary injury caused by long-term retention in vivo after an operation is avoided.
