Abstract: The present application relates to a rope fixation device, a rope transmission device, and an ultrasound probe. The rope fixation device includes a drive shaft, a rope, and a fixing member. The drive shaft is provided with a rope through-hole and a fixing hole. The fixing hole is in communication with the rope through-hole. The rope through-hole penetrates through the drive shaft. Two opposite ends of the rope through-hole are both located on the side wall of the drive shaft. The rope extends through the rope through-hole, and two ends of the rope respectively protrude out from the two opposite ends of the rope through-hole. The fixing member is inserted into the fixing hole. One end of the fixing member adjacent to the rope through-hole includes an end surface. At least part of the end surface abuts against the rope, thereby fixing the rope in the rope through-hole.

Abstract: One or more embodiments of the present disclosure may provide a power structure and an ultrasound probe. The power structure may include a driving assembly. The driving assembly may include a transmission device; the transmission device including a rotation component, a rope and an elastic component, and the rotation component including a driving wheel and/or a driven wheel. The driving wheel may be in a transmission connection to the driven wheel by the rope. The rope may be in an elastic connection to a body of the driving wheel and/or a body of the driven wheel through the elastic component. The rotation component may be provided with an accommodation cavity, and an extension channel in communication with the accommodation cavity. The elastic component may be accommodated in the accommodation cavity. One end of the rope elastically connected to the driving wheel and/or the driven wheel may be located in the accommodation cavity, and a portion of the rope may be located in the extension channel.
