This utility model relates to a fault-prevention mechanism for determining the presence or absence of a built-in copper ring based on visual imaging. It includes a frame, a built-in copper ring placement device, a built-in copper ring placement visual imaging mechanism, a built-in copper ring drop collection device, and a built-in copper ring drop visual imaging mechanism. Compared to traditional manual identification of the presence or absence of a built-in copper ring, this utility model achieves automated detection of the presence or absence of a built-in copper ring.

This invention discloses an ultrasonic phacoemulsification handpiece with a sensor and a surge control system and a method. The central aspiration lumen of the ultrasonic phacoemulsification handpiece consists of two components of plug-in loose fit: a fixed lumen (304) and an extension lumen (305); a small pressure sensor (307) is mounted on the extension lumen (305), but still able to keep the easy-to-use size and maintain the ultrasonic performance of the handpiece. The extension lumen (305) minimizes the effect of ultrasonic vibration on the sensor (307) while maintaining sufficient stiffness for installing and removing the phacoemulsification tip (202). The design of the handpiece transducer reduces the effect of this sensor installation on the ultrasonic performance. For ultrasonic phacoemulsification cataract removal surgery, the short distance from the pressure sensor to the surgical site provides a technical solution for reliably controlling the risk of the post occlusion surge.

The application belongs to the field of fork assembly manufacturing, in particular to a fork bushing press-fitting multi-loading and missing loading mistake proofing method and a press-fitting device, comprising the following steps: 1) setting a first airflow channel and a second airflow channel on a press-fitting rod; 2) measuring the flow rates A1 and A2 in the first airflow channel and the second airflow channel when no bushing is sleeved on the press-fitting rod; 3) setting a flow rate value A11 less than the flow rate A1 and greater than 0 and a flow rate value A22 less than the flow rate A2 and greater than 0 respectively when in use, measuring the flow rate B through the first airflow channel 2 and the flow rate C in the second airflow channel 4; comparing the flow rate value A11 with the measured flow rate value B, and then comparing the flow rate value A22 with the measured flow rate value C, so as to determine whether the bushing is over-loaded or under-loaded.
