Claims

[Scope of utility model registration request]

An ultrasound probe head for transmitting and receiving ultrasound into the body cavity is provided at the tip of the insertion section that is inserted into the body cavity, and a drive system for ultrasound scanning is provided at the proximal side of the second insertion section. In the intrabody cavity ultrasonic diagnostic apparatus, the driving force is transmitted to the head side of the ultrasound probe by a flexible drive shaft and a hard drive shaft, wherein the flexible drive shaft is formed of a tightly wound coil, and both ends thereof are formed of a tightly wound coil. After solidifying by welding or the like, a radial hole is drilled in this solidified portion, one end of the joint is inserted into the end of the flexible drive shaft, and a hole is formed in the end of the joint that communicates with the hole of the flexible shaft. By drilling a hole and inserting an engaging tool such as a pin into both holes, a joint is provided at both ends of the flexible drive shaft, and the other end of the joint is provided with a joint that engages with the end of the hard drive shaft. An intrabody cavity ultrasonic diagnostic device characterized by being provided with a connecting means for fitting.
