Position correction method of osteotomy guide tool and orthopedic surgical system
A method for correcting position of an osteotomy guide tool and an orthopedic operation system are disclosed. A trackable element mounted on the osteotomy guide tool or on the robotic arm tracks the position of the osteotomy guide tool and generates position information of the trackable element. According to the current position and the desired position of the trackable element, a robotic arm drives the osteotomy guide tool and the trackable element to move, until the trackable element is moved to the desired position. This method does not need to consider the absolute position accuracy of the robotic arm, and does not rely on the experience of the surgeon. The tool has several guiding features, which can provide guides for osteotomy operations, so that the same osteotomy guide tool can perform multiple operations of osteotomy and punching, thus greatly reducing the operation time and improving the operation efficiency. |

LED driver and LED lighting system for use with a high frequency electronic ballast
A retrofit LED driver is for connecting to a high frequency ballast and for driving a LED load.

In this way, the effective impedance of the lamp is increased, which enables switching noise to be reduced, meanwhile the overall LED output power is not increased, as desired by the user. |
