Provided is a full-automatic puncture needle developing enhancing method based on pattern recognition. The method comprises the following steps that an ultrasonic probe scans a part to be detected in a vertical mode, and a first ultrasonic image is formed; a puncture needle conducts puncture on the part to be detected at any angle; a puncture angle A of the puncture needle is recognized in a pattern recognition mode; a mainframe controls delay of an array element sound beam of the ultrasonic probe to enable the array element sound beam of the ultrasonic probe to deflect from the vertical direction at a deflection angle B and scan back and forth nearby; a second ultrasonic image taking the puncture needle as the principal thing is formed; a complete ultrasonic image is composited by the first ultrasonic image and the second ultrasonic image. The puncture needle is inserted at any angle, the puncture angle of the puncture needle is automatically obtained through the pattern recognition, the deflection angle B does not need to be preset, and puncture needle developing enhancement is achieved in a full-automatic mode; the deflection angle B of the array element sound beam is calculated out according to the puncture angle A, and deflection does not exist, so that the clearer second ultrasonic image is formed, and the whole puncturing and scanning work is more simple and convenient.

The invention provides an electrophysiological catheter comprising a catheter bendable section, a catheter main body section and a catheter handle, which are connected successively. The distal end of the catheter bendable section is provided with a head electrode. The catheter handle is provided with a knob used for controlling the deflection angle of the catheter bendable section and a push button used for controlling the start position of the deflection of the bendable section. The electrophysiological catheter is characterized in that the distal end of the catheter can be bent into different shapes through the cooperative control of the push button on the catheter handle and a support rod in the catheter, and the knob and a pull wire in the catheter, so that the catheter can enter different diseased locations to fulfill the functions of catheter ablation, stimulation and mapping. Thus, the using convenience is greatly improved and cost is saved.

The invention relates to the technical field of detection, and in particular discloses an automatic detection method. The automatic detection method comprises the following steps of S1, providing an automatic detector which comprises a conveying device and a feeding correction device located above the conveying device; S2, placing a workpiece at a feeding end of the conveying device; S3, detectingwhether a deflection angle of the workpiece on the conveying device is in a preset range or not; if not, rotating the workpiece by the feeding correction device; and S4, detecting the workpiece. According to the automatic detection method, the automatic detector has no requirements on the angle of workpiece fed upstream, the deflection angle is then detected after the workpiece enters the automatic detector, and then the feeding correction device corrects the workpiece to a proper detection state according to the deflection angle to detect the workpiece. According to the automatic detection method, it is unnecessary to position the workpiece before the workpiece enters the automatic detector, so that workpiece production steps are reduced, the production efficiency is improved and the production cost is lowered.
