The invention discloses a novel orthopedic medical detection device, which comprises a socket and a plug connected with the medical detection device. Inserting grooves with a port facing to the rightare arranged in the socket in an up-down manner, and a mounting groove which is communicated with the inserting groove is formed in the end wall which is relatively close to the inserting groove in amatched mode. A power supply block is arranged in the installation groove in a sliding mode, and an arc surface is arranged on the end face, facing the insertion groove, of the power supply block. A first sliding groove is formed in the end wall of the insertion groove, far away from the installation groove. A second sliding groove and a third sliding groove are arranged in the left end wall and the right end wall of the first sliding groove in a matched mode. A first inclined sliding surface and a second inclined sliding surface are arranged in the end wall of the first sliding groove, far away from the inserting groove, in a left-to-right matched manner. A first sliding arm and a second sliding arm which are matched with the first sliding groove in a sliding mode are arranged in the first sliding groove in a left-to-right matched mode.
