Background
An ultrasonic imaging apparatus is an apparatus for detecting and imaging using ultrasonic waves, and is widely used in the fields of medical diagnosis, research, and the like. An ultrasonic probe is an important component of ultrasonic equipment, and is a structure for realizing electric energy and acoustic energy conversion by utilizing the piezoelectric effect of materials.
A mechanical 4D ultrasound probe is one type of ultrasound probe that implements 3D/4D imaging by mechanically fanning an array of elements of the ultrasound probe. Such ultrasonic probes typically include a motor, a drive mechanism, a base, a sound head, a sound window (or sound head housing), and a coupling fluid filled between the ultrasonic sound head and the sound window of the ultrasonic probe. Wherein the coupling liquid is used for enabling the ultrasonic wave to well propagate between the sound head and human tissues. The coupling liquid not only needs to meet certain acoustic matching requirements, but also needs to meet certain viscosity requirements in order to enable the sound head to swing at a certain speed.
However, in practical situations, the viscosity of the liquid is greatly affected by temperature, and in low temperature situations, the viscosity of the coupling liquid is great, which seriously affects the swinging speed of the mechanical 4D ultrasonic probe. Therefore, the current mechanical 4D ultrasonic probes in the industry have clear requirements on the environment temperature in use, and are generally required to be above 20 ℃. This limits the use of mechanical 4D ultrasound probes in hospitals or field visits with poor conditions in alpine regions.

Furthermore, the described features, operations, or characteristics of the description may be combined in any suitable manner in various embodiments. Also, various steps or acts in the method descriptions may be interchanged or modified in a manner apparent to those of ordinary skill in the art. Thus, the various orders in the description and drawings are for clarity of description of only certain embodiments, and are not meant to be required orders unless otherwise indicated.
The numbering of the components itself, e.g. "first", "second", etc., is used herein merely to distinguish between the described objects and does not have any sequential or technical meaning. The terms "coupled" and "connected," as used herein, are intended to encompass both direct and indirect coupling (coupling), unless otherwise indicated.
The present embodiment provides an ultrasonic probe for assisting an ultrasonic apparatus in imaging by transmitting and receiving an ultrasonic signal. The ultrasonic device can be related devices such as an ultrasonic diagnostic apparatus and the like. The following description will be given specifically taking a mechanical 4D ultrasonic probe applied to a 3D/4D imaging apparatus as an example, but of course, the structure shown in this embodiment can be applied to other ultrasonic probes that need to heat a coupling liquid.
Referring to fig. 1, the ultrasonic probe 100 includes a receiving cavity (a space for placing the sound head 110 in the figure, and a portion thereof overlaps with the filling area 120, so it is not shown), the sound head 110, and a heating unit 130. The sound head 110 is installed in the accommodating cavity, and the outer wall of the sound head 110 and the inner wall of the accommodating cavity enclose a filling area 120 for filling the coupling liquid 140.
The sound head 110 may transmit ultrasonic waves and receive corresponding echo signals, thereby performing ultrasonic imaging on human tissues or organs. The sound head 110 is mounted in the receiving chamber. The housing cavity is typically formed by enclosing several components in the probe, such as at least a portion of the cavity walls of the housing cavity formed by enclosing the base 150 and the acoustic window 160, such as: the receiving cavity may be entirely enclosed by the base 150 and the acoustic window 160, or the receiving cavity may be enclosed by the base 150, the acoustic window 160, and other components.
In order to allow the ultrasound to propagate well between the sound head 110 and the human tissue, the filling area 120 is filled with a coupling liquid 140. The heating unit 130 is designed for the coupling liquid 140, and is specially used for heating the coupling liquid 140 in the filling area 120, so that the coupling liquid 140 can reach a proper temperature under a low-temperature environment, and the normal use of the probe is ensured. The design can break through the low-temperature environment use limit of the ultrasonic probe 100 (especially the mechanical 4D ultrasonic probe) and can improve the medical diagnosis level of people under the hard conditions in the alpine region.
The heating of the coupling liquid 140 by the heating unit 130 may be achieved by extending the heating unit 130 into the filling area 120, directly contacting the coupling liquid 140, or by heating a component contacting the coupling liquid 140, for example, heating the cavity wall of the receiving cavity and/or the sound head 110. Of course, in contrast, heating the coupling liquid 140 directly by the heating unit 130 is more efficient in heating, facilitating faster and more heat transfer into the coupling liquid 140.
The heating unit 130 may include a resistive heating device and/or an infrared heating device, among others. Of course, other structures that enable heating of coupling fluid 140 may also be included.
The ultrasound probe 100 may also include other structures, only briefly described or omitted herein. For example, as shown in fig. 1, the ultrasonic probe 100 may further include a motor 180, a transmission mechanism 190, and the like, and the motor 180 drives the transmission mechanism 190 to move, thereby driving the sound head 110 to swing in the accommodating cavity.
Referring to fig. 1, in one embodiment, the probe 100 includes a base 150 and an acoustic window 160 (or acoustic head housing), and the heating unit 130 is mounted on the base 150. Preferably, the heating unit 130 passes through the base 150 and protrudes into the filling area 120, so that the coupling liquid 140 in the filling area 120 can be directly heated.
Of course, in other embodiments, the heating unit 130 may be disposed on other components, for example, the heating unit 130 contacts the wall of the accommodating cavity, and heats the coupling liquid 140 through heat conduction of the wall.
Referring to fig. 1, in one embodiment, the probe 100 further includes a temperature sensor 170, and the temperature sensor 170 is configured to detect a temperature of the coupling liquid 140 in the filling area 120, so that an operator can manually or automatically control the operation state of the heating unit 130 according to the detected temperature information. The operating state includes the activation, the deactivation, the power, etc. of the heating unit 130.
Of course, in some embodiments, the probe 100 may include only the heating unit 130, with the operator manually or the control unit automatically controlling the activation and deactivation of the heating unit 130, such as by estimating the heating time to determine the operating time of the heating unit 130. Of course, the use of the temperature sensor 170 to control the heating temperature may be more advantageous to heat the temperature of the coupling liquid 140 to a desired range.
In an automatic control mode, a control unit (not shown) is further included. The temperature sensor 170 is connected to the control unit for transmitting detection data to the control unit. The control unit is connected to the heating unit 130, and is configured to control an operation state of the heating unit 130 according to the detection data. For example, when the control unit detects that the temperature of the coupling liquid 140 is lower than the use temperature, e.g., 20 ℃, the heating unit 130 may be controlled to heat the coupling liquid 140 to the optimal use temperature of the ultrasonic probe 100, e.g., 25-30 ℃. The automatic control mode by the control unit is more accurate than manual control by an operator, meanwhile, the actions of the operator can be reduced, and the using convenience of the probe 100 is improved.
In one embodiment, after the probe 100 is turned on, the system automatically detects the actual temperature of the coupling solution 140 through the temperature sensor 170, and if the measured temperature is lower than the usage temperature of the probe 100, the heating unit 130 may be instructed to heat the coupling solution 140 to a set temperature, which may be set according to the characteristics of the coupling solution 140.
The temperature sensor 170 may be configured to detect the temperature of the coupling liquid 140 by directly contacting the coupling liquid 140 with the temperature sensor 170, or by detecting the temperature of a component in contact with the coupling liquid 140, for example, detecting the temperature of the cavity wall of the receiving cavity and/or the sound head 110. Of course, in contrast, the temperature sensor 170 directly detects the temperature of the coupling liquid 140 more accurately and with higher reference.
Referring to fig. 1, in one embodiment, the temperature sensor 170 extends into the filling area 120 and directly contacts the coupling liquid 140 to detect the temperature of the coupling liquid 140.
Specifically, the temperature sensor 170 may be mounted on the base 150. Preferably, the temperature sensor 170 passes through the base 150 and protrudes into the filling area 120 to directly detect the temperature of the coupling liquid 140, thereby improving the accuracy of temperature detection.
The present embodiment provides an ultrasonic apparatus, which may be an ultrasonic diagnostic apparatus or the like, for example, a 4D ultrasonic diagnostic apparatus.
The ultrasonic equipment comprises a host machine used for controlling the ultrasonic probe and the ultrasonic probe used for sending and receiving ultrasonic signals, wherein the ultrasonic probe is connected with the host machine and used for feeding back relevant information to the host machine.
The ultrasonic probe adopts any structure as shown in the embodiment, and the ultrasonic probe of the structure is provided with the heating unit and is specially used for heating the coupling liquid in the filling area so that the coupling liquid can reach proper temperature under the low-temperature environment, thereby ensuring the normal use of the probe. The design can break through the use limit of the ultrasonic probe (especially the mechanical 4D ultrasonic probe) in the low-temperature environment, and can improve the medical diagnosis level of people under the hard condition in the alpine region.
The foregoing description of specific examples has been presented only to aid in the understanding of the present application and is not intended to limit the present application. Variations of the above embodiments may be made by those of ordinary skill in the art in light of the concepts of the present application.
