摘要： A mechanism for sequentially loading and unloading a biopsy instrument includes a first wheel operatively connected with a cannula, the first wheel being rotatably mounted upon an axle such that the axle urges rotation of the first wheel in a first direction to transfer the cannula and the first wheel to a loaded position, the first wheel being configured for selective rotation with respect to the axle in a second direction to transfer the cannula and the first wheel to an unloaded position. A second wheel is operatively connected with a stylet, the second wheel being configured to be rotated by the axle in the first direction when the first wheel is in the loaded position, the second wheel configured for rotation relative to the axle to transfer the stylet and second wheel from the loaded to unloaded position. The second wheel is operatively engaged with the first wheel to allow partial rotation of the second wheel in the second direction with respect to the first wheel and urging similar rotation of the first wheel in the second direction after at least some duration of relative rotation of the second wheel with respect to the second wheel.
