Abstract: A removable dual gold marker implantation device with minor damage comprises a gold marker and a puncture needle, the gold marker is arranged in the needle barrel of the puncture needle when in use; the gold marker comprises a gold marker head and a connecting wire connected with the gold marker head; the gold marker head comprises a first gold marker, a connecting part and a second gold marker connected in sequence. The disclosure reduces the damage to the body when removing the gold marker, and the dual gold marker structure makes the implantation of multiple gold markers at the same time possible and reduces the number of times of implantation and improves the efficiency.

Abstract: A gold marker recovery device for radiotherapy positioning and its using method comprises a positioning gold marker and a recovery clamp, the positioning gold marker comprises a gold marker body and an elastic fixed structure, the elastic fixed structure comprises a fixed segment, an extending segment and a spiral segment connected in sequence; the fixed segment is embedded in the gold marker body so that the fixed segment is closely connected with the gold marker body, A magnetic ball is arranged at one end of the gold marker body away from the extending segment; the recovery clamp comprises an operating handle, the rear end of the operating handle is connected with an outer sheath tube in a hollow structure, and the outer sheath tube is connected with a zipper for driving the clamp to open and close.
