Cooling mechanism and ultrasonic probe

Abstract

The invention provides a cooling mechanism and an ultrasonic probe. The cooling mechanism is used for dissipating heat of the multi-plane ultrasonic probe. According to the technical scheme, the cooling mechanism is arranged inside the ultrasonic probe and comprises a refrigerant feeding pipe, a refrigerant exhaust pipe and a sealing baffle. The sealing baffle is connected with an outer protective shell in a sealing mode to form a sealing cavity which is used for containing an energy converter unit and part of a revolving mechanism. A first through hole, a second through hole and a third through hole are formed in the sealing baffle, wherein the third through hole allows the revolving mechanism to penetrate through. The refrigerant feeding pipe is connected with the first through hole in a sealing mode, the refrigerant exhaust pipe is connected with the second through hole in a sealing mode, the refrigerant feeding pipe is used for feeding refrigerant to the sealing cavity, and the refrigerant exhaust pipe is used for exhausting the refrigerant out of the sealing cavity. By the implementation of the technical scheme, the multi-plane ultrasonic probe in a working state can be effectively cooled, and the working temperature of the multi-plane ultrasonic probe is controlled at about 37 DEG C which is about the same as the temperature of the human body.

Description

technical field [0001] The invention relates to the technical field of ultrasonic diagnostic instruments, in particular to a cooling mechanism and an ultrasonic probe. Background technique [0002] Ultrasonic Probe is an ultrasonic diagnostic instrument that inserts the transducer unit into the body cavity of the subject. Please refer to figure 1 , the transducer unit 110 is located in the insertion part 11, the insertion part 11 is used to be inserted into the cavity of the subject, and the grip part 12 is used to be held by an operator outside the cavity. When the transducer unit 110 is working, a large amount of heat is generated so that the temperature of the insertion part 11 rises. If the heat dissipation is not timely, the transducer unit 110 will be damaged or discomfort in the body cavity of the subject will be caused. [0003] Currently, one way to dissipate heat is through a liquid cooling system, see figure 2 , there is a transducer unit 201 and a heat dissipa...

Problems solved by technology

[0004] However, the above as figure 2 In the first technical solution shown, the heat dissipation unit needs to be in direct contact with the transducer unit, that is, there cannot be relative positional movement between the transducer unit and the heat dissipation unit. This limitation makes this technical solution not suitable for energy conversion A multi-plane ultrasonic probe whose unit can rotate; in the second technical solution above, the thermal conductivity of the silicone grease cannot meet the heat dissipation requirements of the continuous use of the multi-plane ultrasonic probe: the temperature of the insertion part of the multi-plane ultrasonic probe will increase with the power-on time. Requires shutdown to cool down when temperature reaches threshold, thus increasing diagnostic time with multiplanar ultrasound probes and placing additional physiological burden on the subject
