no. 2 Embodiment approach
[0096] Below, refer to Figure 4 An example of the cable portion in the ultrasonic probe according to the second embodiment of the present invention will be described.
[0097] Figure 4 It is a sectional view showing the cable portion of the ultrasonic probe according to the second embodiment of the present invention. Figure 4 The ultrasonic probe of the second embodiment shown and figure 2 The ultrasonic probe of the first embodiment is different in that the refrigerant pipe portion is replaced with a porous pipe having four independent holes in the longitudinal direction.
[0098] The cable portion 2b has a circular cross section, and a porous tube 22b having a circular cross section is disposed near the center of the cross section. In addition, the perforated tube 22b is made of a soft material with high heat insulation properties such as silicone rubber and soft vinyl chloride resin, and forms two refrigerant supply flow paths 22b1 and refrigerant discharge flow path...
no. 3 Embodiment approach
[0103] Below, refer to Figure 5 An ultrasonic probe according to a third embodiment of the present invention will be described.
[0104] Figure 5 It is a sectional view showing the cable portion of the ultrasonic probe according to the third embodiment of the present invention. Figure 5 The ultrasonic probe of the third embodiment shown and figure 2 The ultrasonic probe of the first embodiment is different in that the refrigerant discharge pipe is provided away from the center of the cable part.
[0105] The cross section of the cable portion 2c is circular, and the refrigerant supply pipe 23c is disposed near the center of the cross section. A plurality of signal lines 21 are arranged on the outer periphery of the refrigerant supply pipe 23 c, and shielded wires 26 of the signal lines 21 are arranged on the outer periphery of the signal lines 21 . In addition, the shielded wire 26 is covered with a clad wire 27 for insulation, protection, and the like.
