Description
Technical Field
The utility model relates to a liver elasticity detection device for detecting liver elasticity.
Background
In the diagnosis of liver diseases, it is often necessary to test the elasticity of the liver. Currently, as a device for detecting the elasticity of the liver, a liver transient elastography technology detector or the like is known.
The liver instantaneous elastography technology detector is provided with a host and a probe. The probe is placed on the body surface of a human body near the liver, and can detect elastic signals related to the elasticity of the liver, so that the host can detect the elasticity value of the liver based on the elastic signals. Specifically, a low frequency vibration signal and a high frequency tracking signal are transmitted from the probe to the liver either simultaneously or sequentially, and as the low frequency vibration signal passes through the liver tissue, an elastic shear wave is generated, the wave velocity of which is related to the elasticity of the liver tissue, i.e., the higher the hardness of the liver, the faster the wave velocity. The shear wave is tracked by the high-frequency tracking signal to detect the wave velocity of the shear wave, and the elasticity of the liver is detected according to the returned high-frequency tracking signal.
However, when the above-described liver instantaneous elastography technique detector is used, it is necessary to determine the position of the liver in advance by using another device such as an ultrasonic detector, and to place the probe at a position aligned with the liver. Therefore, not only the operation is complicated, but also the operator is required to have sufficient expertise.
Moreover, when the liver transient elastography technology detector is used, the probe can only detect a certain point on the liver. However, the liver contains multiple liver segments, and there are differences in elasticity values for different liver segments. Therefore, the elasticity value of the liver is detected without knowing the detected liver segment, and an erroneous diagnosis may be made.

Detailed Description
Hereinafter, an embodiment of the liver elasticity detection device according to the present invention will be described with reference to the drawings. However, the configurations described in the following embodiments are merely examples, and are not intended to limit the present invention.
< first embodiment >
Fig. 1 is a schematic diagram of the overall structure of a liver elasticity test apparatus. The liver elasticity detection device includes a control unit 1 and a detection unit 2. In fig. 1, the control unit 1 and the detection unit 2 are separate components, but the control unit 1 may be integrated with the detection unit 2.
The control unit 1 controls the detection unit 2, and processes the elasticity signal relating to the elasticity of the liver detected by the detection unit 2 to obtain an elasticity value of the liver.
The detection unit 2 is connected to the control unit 1 via a cable. When detecting the elasticity of the liver, the detecting unit 2 is placed on the body surface of the human body corresponding to the liver to acquire a signal relating to the elasticity of the liver.
As a method for detecting liver elasticity, the conventional instantaneous elasticity imaging technique of the liver may be used, or other techniques may be used.
Next, a specific configuration of the detection unit 2 will be described with reference to fig. 2.
The shape of cover 21 is not limited to the circular shape shown in fig. 2, and may be other shapes such as a rectangular shape and an elliptical shape. Preferably, the hood 21 may be formed in a size capable of covering the entire liver. For example, the area of the bottom surface of the hood 21 is preferably 150cm 2 The above.
In the present embodiment, support portion 23 is a flange formed on the outer periphery of the bottom surface of cover portion 21. The structure is not limited to this, and for example, a plurality of support points formed on the bottom surface of the cover portion 21 may be provided as long as the bottom surface of the cover portion 21 can be separated from the body surface of the human body.
A probe 22 is movably provided on the bottom surface of the cover 21. The probe 22 is a member for acquiring an elasticity signal relating to the elasticity of the liver, and the movement of the probe on the bottom surface is controlled by the control unit 1.
As a mechanism for moving the probe 22 on the bottom surface, various planar moving mechanisms can be employed. For example, when the bottom surface of the cover 21 is formed in a circular shape as shown in fig. 3, a guide rail 24 that can rotate around the center of the bottom surface and extends in the radial direction may be provided, and the probe 22 may be movably provided on the guide rail 24. Thus, by controlling the rotation of the guide rail 24 and the movement of the probe 22 on the guide rail 24, the probe 22 can be moved to an arbitrary position on the bottom surface.
For example, when the bottom surface of the cover 21 is formed in a rectangular shape, a guide rail that can move in one direction may be provided, and the probe 22 may be provided on the guide rail so as to be movable in a direction perpendicular to the one direction. Accordingly, the probe 22 can be moved to an arbitrary position on the bottom surface by controlling the movement of the guide rail or the probe in two directions perpendicular to each other.
With the above configuration, since the probe 22 can move on the bottom surface of the cover portion 21, the probe 22 can move to a position corresponding to an arbitrary hepatic segment of the liver and detect the hepatic segment without manually moving the detection portion 2 to find the detection position. Further, since the control unit 1 controls the position of the probe 22, the operator can move the probe 22 to the detection position corresponding to the selected hepatic segment simply by selecting the hepatic segment to be detected on the control unit 1. Thus, the elasticity values of the respective liver segments can be accurately obtained.
In addition, the movement of the probe 22 is not limited to movement on the bottom surface. The probe 22 may be provided with a rotation mechanism for rotating the probe, a tilting mechanism for changing the orientation of the probe, and the like. As an example of the rotation mechanism and the tilt mechanism, for example, as shown in fig. 4, the probe 22 is supported by a holder 25 so as to be capable of tilting, and the holder 25 is rotatably provided on the bottom surface of the cover 21. By providing such a multi-dimensional movement mechanism, the probe 22 can cover a wider range. Thus, even if the mask portion 2 is reduced in size, the detection range of the probe 22 can be made to cover the entire liver. Further, since the orientation of the probe 22 can be adjusted, the probe can be aligned with the liver in an appropriate posture, and the accuracy of detection can be improved.
The liver elasticity detecting apparatus according to the present embodiment may include a holder for fixing the detecting unit 2. The structure of the holder may be, for example, a structure in which the detection unit 2 is supported and fixed on the body of the patient, or a structure in which the detection unit 2 is supported and fixed on a bed on which the patient lies. Because the detection part 2 does not need to be moved after the detection part 2 is placed on the body surface of the human body near the liver, the position of the detection part 2 relative to the body surface of the human body can be fixed by using the fixing frame, and the influence of the movement of the detection part 2 on the elasticity detection can be avoided.
Next, a configuration for specifying the detection position of the probe 22 in the present embodiment will be described.
Fig. 5 is a schematic diagram of the liver elasticity detection device according to the present embodiment. Wherein the control section includes a detection position determination section. The detection device determination unit may be realized by the control unit, or may have another structure provided independently.
The detection unit 2 is also provided with an imaging detection unit for detecting an image of the liver. As the configuration of the imaging detection unit, for example, a configuration based on an ultrasonic detection image may be adopted, and other configurations may be adopted. The imaging detection unit may be provided independently of the detection unit, or may be provided directly to the probe 22.
The liver is scanned and imaged by the imaging detection unit, and the detection position determination unit can determine the detection position corresponding to each hepatic segment from the detection image of the liver.
In the case where the imaging detection unit is provided in the probe 22, a detection image of the position may be obtained while detecting the elasticity of the liver. The detection position specifying unit specifies, from the detection image, a liver elasticity value detected as an elasticity value of a detection position corresponding to which hepatic segment.
With the above configuration, since the imaging detection unit is provided in the detection unit, detection can be completed only by the present liver elasticity detection apparatus without the need for assistance from another device. In addition, the detection position is determined by the detection position determining unit of the control unit based on the detection image of the liver, so that the elasticity values of different liver segments on the liver can be easily and accurately detected, and erroneous judgment caused by insufficient experience of the operator can be avoided.
< second embodiment >
Next, a liver elasticity detection device according to a second embodiment will be described. The present embodiment differs from the first embodiment only in the configuration for specifying the detection position of the probe 22, and therefore, descriptions of other configurations are omitted.
Fig. 6 is a schematic diagram of a liver elasticity detecting apparatus of a second embodiment. Wherein the control section includes a detection position determination section. The detection position specifying unit specifies the detection position based on the elastic signal from the probe 22 of the detection unit.
Specifically, the probe 22 performs elasticity detection while scanning the entire liver, and transmits an elasticity signal obtained by the probe 22 at each position to the control unit. The control unit obtains an elasticity value for each position based on the elasticity signal. The detection position specifying unit specifies the position range of the entire liver based on the difference in elasticity between the liver and other tissues around the liver. Further, the detection position corresponding to each liver segment is determined based on the position range of the entire liver.
With the above configuration, the same technical effect as that of the first embodiment can be obtained, that is, the detection can be completed only by the present liver elasticity detection device, the elasticity values of different liver segments on the liver can be easily and accurately detected, and erroneous judgment due to insufficient experience of the operator can be avoided.
< third embodiment >
Next, a liver elasticity detection device according to a third embodiment will be described. The present embodiment is different from the first and second embodiments described above in that the control unit 1 is not provided with a detection position specifying unit, but a plurality of detection positions are set in advance in the detection unit 2. Therefore, the configuration of the detection unit according to the third embodiment will be described below, and descriptions of other configurations will be omitted.
Fig. 7 is a schematic view as viewed from the bottom surface of cover 21 of detection unit 2. As shown in fig. 7, a plurality of detection positions indicated by broken lines are set in advance on the bottom surface of the cover portion 21. These detection positions may be set to correspond to different liver segments of the liver, respectively, according to the normal liver. For example, in fig. 7, detection position a corresponds to the upper right anterior lobe of the liver, detection position b corresponds to the lower right anterior lobe of the liver, detection position c corresponds to the upper left outer lobe of the liver, and detection position d corresponds to the lower left outer lobe of the liver.
With the above configuration, the operator can align the plurality of detection positions with the corresponding hepatic segment of the liver only by aligning two of the plurality of detection positions with the corresponding hepatic segment of the liver. Therefore, the elasticity value of each liver segment can be accurately obtained, the trouble of checking the positions of the liver segments one by an operator is saved, and the operation is simpler and more convenient.
The configuration of the liver elasticity detection device according to each embodiment is explained above. Further, the configurations of the above embodiments may be omitted, combined, or replaced.
