Description

Technical Field

[0001] The utility model belongs to the field of medical equipment and relates to a terminal transfer structure of a mechanical arm of an operating table. Background Art

[0002] The operating trolley is a robot-assisted tool used by doctors during surgery. The power tools connected to the end of the robotic arm on the existing operating trolley usually include a power source to drive the movement of the end effector on the power tool. For example, a filing device composed of a filing rod, a filing head and a bracket has a bone drill connected to its rear end to drive the rotation of the filing rod and the filing head. This type of power source usually requires continuous power supply. The existing power supply method cannot directly provide electricity to the power source through the robotic arm, but connects the trolley or an external power supply through a power cord. This causes the power cord of the power source to be too long and easy to droop, and is easy to get hooked during use, causing inconvenience or risk in use. Utility Model Content
