| Objective To design and make a micro-drive multidimensional mechanical arm, which drive ultrasound transducer to take sample of carotid artery. Methods According to the principle of mechanics and electricity, a simplification vice-structure is used as mechanical arm and micro-motor is used as drive device. Results Developed and made a multiple-free mechanical arm motor can control every parallel movement at 2mm. Conclusion The self-made mechanical arm has a reasonable design, simple structure, convenient use and got the clinic acceptance. |
