Problems solved by technology

When the pump for circulating the refrigerant, the radiator, and the storage window for the refrigerant are stored inside the probe connector, if a large radiator is stored in the probe connector, the size of the probe connector will increase a lot of
In addition, it is necessary to build a pump for circulating the cooling medium, a heat sink for the cooling medium, and a radiator fan for exothermic cooling in the probe connector part, which increases the size of the probe connector part.
In this way, since the cooling system will become larger if the cooling capacity is increased, it is difficult to satisfy both the improvement of the cooling capacity and the miniaturization of the cooling system.
[0019] In addition, in the case of cooling the ultrasonic probe using the conventional cooling system, the ultrasonic probe will be cooled even if the temperature of the probe part does not rise. Cools more than needed, so there is also the problem of poor energy efficiency

no. 2 Embodiment approach

[0097] 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.

[0098] 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 is different from the ultrasonic probe of the first embodiment shown in FIG. 2 in that the refrigerant pipe portion is replaced with a porous pipe having four independent holes in the longitudinal direction.

[0099] 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 p...

no. 3 Embodiment approach

[0104] Below, refer to Figure 5 An ultrasonic probe according to a third embodiment of the present invention will be described.

[0105] 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 according to the third embodiment shown in FIG. 2 is different from the ultrasonic probe according to the first embodiment shown in FIG. 2 in that the refrigerant discharge pipe is provided away from the center of the cable portion.

[0106] 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, pr...

Abstract

The invention provides an ultrasonic probe and an ultrasonic diagnosis apparatus, the ultrasonic probe comprising a transducer part, a heat-receiving part, a refrigeration unit and a cable unit. The cable unit includes a signal line, a refrigerant supply tube, a refrigerant ejection tube and a heat insulator. The heat-receiving part absorbs heat generated from the transducer part. The refrigerant supply tube supplies a refrigerant from the refrigeration unit to the heat-receiving part. The refrigerant ejection tube sends the refrigerant for ejecting heat of the heat-receiving part to the refrigeration unit. The heat insulator is arranged around the refrigerant supply tube. A set of the refrigerant supply tube, the refrigerant ejection tube and the heat insulator is arranged at a center of the cable unit substantially while the signal line is arranged around at least one of the refrigerant supply tube, the refrigerant ejection tube and the heat insulator.

Description

[0001] This application is a divisional application of the Chinese invention patent application with the application number 200510116041.8 and the invention title "ultrasonic probe and ultrasonic diagnostic device" submitted by the same applicant on October 27, 2005. technical field [0002] The present invention relates to an ultrasonic probe and an ultrasonic diagnostic device, in particular to an ultrasonic probe and an ultrasonic diagnostic device equipped with a cooling mechanism.
