An open-close-repeatable rotatable hemoclip for the gastrointestinal tract with electrocoagulation is provided by the present invention, including a clamping assembly, a tightening assembly, an insulating outer tube assembly and a handle assembly. The clamping assembly is rotatable and open-close-repeatable under actions of the handle assembly, the insulating outer tube assembly and the tightening assembly. An electrode is arranged inside the handle assembly. The electrode is electrically connected to the clamping assembly through the insulating outer tube assembly and the tightening assembly. The hemoclip of the present invention can be easily rotated inside the human body according to various angle requirements. When a flaky and irregular bleeding occurs, a high frequency electric power can be introduced for an electrocoagulation hemostasis.

The present invention is generally related to an electronic ballast, an ignition control apparatus used therein and associated method of operation. In one embodiment, an electronic ballast comprising an inverter and an ignition control apparatus which comprises a stability monitoring circuit and a controlled ignition circuit. The inverter converts a DC input voltage into an AC voltage to drive a gas discharge lamp. The stability monitoring circuit monitors whether the DC input voltage is stable. The controlled ignition circuit is electrically coupled to the stability monitoring circuit and the lamp, ignites the lamp based on the monitoring result. The controlled ignition circuit does not ignite the gas discharge lamp until the DC input voltage becomes stable.
