[0002] With the increasingly widespread use of ultrasound probes in medicine, a variety of ultrasound probe products have emerged on the market. The main difference between different styles of probes lies in their different fields of use. Using the angle sensor in the ultrasound probe to position patients who are to undergo lumbar spinal anesthesia before puncture can improve the success rate of a single puncture, reduce the number of punctures, and thus reduce the risks and complications of multiple punctures.

[0003] However, due to the installation deviation of the ultrasound probe, long-term use or vibration during transportation, the positioning accuracy of the angle sensor in the ultrasound probe will be greatly affected, making it impossible to provide accurate positioning information to the doctor, affecting the success rate of subsequent puncture.

[0016] In an optional embodiment, a second limiting groove is provided on the first slot and the second slot, and the second limiting groove is suitable for fixing the ultrasonic probe.

[0017] Beneficial effect: The utility model provides second limiting grooves on the first slot and the second slot respectively, so that the ultrasonic probe can be firmly fixed in the first slot or the second slot during the angle calibration process, thereby preventing the ultrasonic probe from moving or shaking during the calibration process, thereby ensuring the calibration accuracy of the angle sensor.

The ultrasound probe is suitable for being clamped in the fixed bracket through the third slot, and the head end of the ultrasound probe extends out of the third slot.

[0025] Beneficial effect: The utility model can ensure that the fixed bracket always maintains a horizontal state on the ultrasonic probe host by arranging a horizontal detection device on the fixed bracket, so that after the ultrasonic probe is set on the fixed bracket through the third slot, the angle sensor in the ultrasonic probe can be calibrated by utilizing the structure of the ultrasonic probe host itself.

[0026] In an optional embodiment, a guide protrusion is provided on the outer periphery of the ultrasonic probe along the length direction of the ultrasonic probe, and a guide groove matched with the guide protrusion is provided in the third slot.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0042] Aiming at the problem that factors such as installation errors lead to deviations in positioning accuracy of an angle sensor in an ultrasonic probe, the utility model provides an ultrasonic probe calibration device and an ultrasonic probe calibration system.

[0043] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0044] According to an embodiment of the present utility model, on one hand, an ultrasonic probe calibration device is provided, which is suitable for calibrating the angle sensor 101 inside the ultrasonic probe 1, and includes: a leveling base 2, a leveling member 3 and a leveling pad 4.

[0045] Specifically, the upper surface of the leveling base 2 is suitable for horizontally and vertically placing the ultrasonic probe 1, and a horizontal detection device 201 is provided at one end of the leveling base 2; the leveling member 3 is arranged on the lower surface of the leveling base 2, suitable for adjusting the leveling base 2 to a horizontal state; the leveling pad 4 is arranged on the upper surface of the leveling base 2, suitable for adjusting the ultrasonic probe 1 to a horizontal state.

[0046] The process of the ultrasonic probe calibration device in the embodiment of the present utility model to calibrate the angle sensor 101 in the ultrasonic probe 1 is as follows:

[0047] For ease of introduction, Figure 1 and Figure 3 As shown, the length direction of the head end of the ultrasonic probe 1 is specified as the X-axis direction of the angle sensor 101, the width direction of the head end of the ultrasonic probe 1 is specified as the Y-axis direction of the angle sensor 101, and the length direction of the ultrasonic probe 1 is specified as the Z-axis direction of the angle sensor 101.

[0048] Example 1:

[0049] like Figure 1 As shown, the ultrasonic probe 1 is placed horizontally on the leveling base 2 using the leveling pad 4, and then the level detection device 201 disposed on the leveling base 2 is observed. If the level detection device 201 shows that the leveling base 2 is not in a horizontal state, the leveling base 2 can be leveled by the leveling member 3 located on the lower surface of the leveling base 2 until the level detection device 201 shows that the leveling base 2 is in a horizontal state. At this time, if the angle of the angle sensor 101 on the X-axis and the Z-axis is not zero, the X-axis and the Z-axis of the angle sensor 101 can be zeroed and calibrated by the control handle described below.

[0050] Example 2:

[0051] like Figure 3 As shown, the ultrasonic probe 1 is placed vertically on the leveling base 2, and then the level detection device 201 disposed on the leveling base 2 is observed. If the level detection device 201 shows that the leveling base 2 is not in a horizontal state, the leveling base 2 can be leveled by the leveling member 3 located on the lower surface of the leveling base 2 until the level detection device 201 shows that the leveling base 2 is in a horizontal state. At this time, if the angle of the angle sensor 101 on the X-axis and the Y-axis is not zero, the X-axis and the Y-axis of the angle sensor 101 can be zeroed and calibrated by the control handle below.

[0052] It should be noted that Examples 1 and 2 are only descriptions of the angle calibration operation of the angle sensor 101 in the ultrasonic probe 1 using the ultrasonic probe calibration device, and do not limit the angle calibration order of the X-axis, Y-axis and Z-axis of the angle sensor 101. That is, when the ultrasonic probe calibration device in this embodiment is used to calibrate the angle of the angle sensor 101, the ultrasonic probe 1 can be placed horizontally on the leveling base 2 first, and the X-axis and Z-axis can be calibrated. Then, the ultrasonic probe 1 can be placed vertically on the leveling base 2, and then the Y-axis can be calibrated. In addition, the angle sensor 101 in this embodiment can be one or more of a single-axis inclination sensor, a dual-axis inclination sensor, a single-axis gyroscope or a three-axis gyroscope, which is not specifically limited here. For example, the angle sensor 101 in the ultrasonic probe 1 can be three single-axis inclination sensors, or it can be a single-axis inclination sensor and a dual-axis inclination sensor.

[0053] In a specific embodiment, the angle sensor 101 in the ultrasonic probe 1 is a three-axis gyroscope. Compared with the combination of a single-axis tilt sensor and a combination of a single-axis tilt sensor and a dual-axis tilt sensor, the use of a three-axis gyroscope can reduce the number of connectors used for installation and fixation, thereby reducing production costs. In addition, the internal space of the ultrasonic probe 1 occupied by the angle sensor 101 can be reduced, which is conducive to the development of miniaturization of the ultrasonic probe 1.

[0054] It should be noted that the level detection device 201 can be a level ruler, and the leveling member 3 can be a leveling knob. By tightening or unscrewing the leveling knob, the leveling of each position of the leveling base 2 can be achieved. In addition, the number of leveling knobs can be two, three or four, which is not specifically limited here. Similarly, the distribution of the leveling knobs on the leveling base 2 can be arranged in pairs, or a leveling knob can be arranged at each corner of the leveling base 2, which is not specifically limited here, as long as the leveling base 2 can be leveled.

[0055] The embodiment of the utility model adjusts the leveling base 2 to a horizontal state by using the leveling member 3 and the level detection device 201, and then adjusts the placement state of the ultrasonic probe 1 on the leveling base 2, thereby realizing zero calibration of the angle of the angle sensor 101. In addition, by arranging the leveling pad 4 on the leveling base 2, it is also possible to overcome the problem that the ultrasonic probe 1 cannot be horizontally arranged on the leveling chassis due to the inconsistent shape and appearance at different positions of the ultrasonic probe 1.

[0056] According to an embodiment of the present invention, a fixing assembly 5 is provided at one end of the leveling base 2 away from the leveling pad 4, and the fixing assembly 5 includes a first slot 501 opening vertically upward and a second slot 502 opening toward the leveling pad 4, and the shapes of the first slot 501 and the second slot 502 are adapted to the shape of the head end of the ultrasonic probe 1. The embodiment of the present invention can ensure that the position state of the ultrasonic probe 1 on the leveling chassis will not change when the angle sensor 101 in the ultrasonic probe 1 is leveled, thereby avoiding the introduction of other errors and affecting the accuracy of calibration.

[0057] It should be noted that the shape of the fixing component 5 can be a rectangular parallelepiped, a cube or a cylinder, as long as the fixing component 5 has a first groove 501 and a second groove 502 that are compatible with the head end of the ultrasound probe 1, and after the ultrasound probe 1 is placed in the first groove 501 and the second groove 502, the position of the ultrasound probe 1 can be fixed.

[0058] Exemplarily, the upper end surface of the leveling base 2 is rectangular, the fixing component 5 is in the shape of a cuboid, and is disposed at one end of the leveling base 2 away from the leveling pad 4 .

[0059] In another example, the upper end surface of the leveling base 2 is rectangular, and the fixing component 5 is in the shape of a cylinder and is arranged at the end of the leveling base 2 away from the leveling pad 4. It can be understood that, compared with setting the shape of the fixing component 5 as a rectangular parallelepiped or a cube, setting the shape of the fixing component 5 as a cylinder can reduce the number of sharp edges of the fixing component 5 itself and reduce the risk of workers being scratched during operation. It should be noted that in order to ensure the firmness of the connection between the cylindrical fixing component 5 and the leveling base 2, the end of the fixing component 5 that abuts against the leveling base 2 can be set to a plane, thereby increasing the contact area between the leveling base 2.

[0060] According to an embodiment of the utility model, at least one first limiting protrusion is provided at one end of the fixing component 5 that abuts against the leveling base 2, and a first limiting groove corresponding to the first limiting protrusion is provided on the upper surface of the leveling base 2. The embodiment of the utility model realizes a detachable connection between the fixing component 5 and the leveling base 2 through the mutual cooperation of the first limiting protrusion on the fixing component 5 and the first limiting groove on the leveling base 2, so that different fixing components 5 can be replaced on the leveling base 2 to meet the operation of angle calibration of the angle sensor 101 in the ultrasonic probe 1 of different shapes.

[0061] It should be noted that the end of the fixing component 5 that abuts against the leveling base 2 may be provided with one, two or four first limiting protrusions, which are not specifically limited here. In addition, the layout of the first limiting protrusions on the fixing component 5 may also be in various forms, for example, two or more are arranged oppositely on the end surface where the fixing component 5 abuts against the leveling base 2, or multiple are arranged at intervals on one side of the end surface where the fixing component 5 abuts against the leveling base 2, which are not specifically limited here. It is understandable that the first limiting protrusion may also be arranged on the leveling base 2, and the first limiting groove may be arranged on the fixing component 5; or both the first limiting protrusion and the first limiting groove may be arranged on the leveling base 2, and the corresponding first limiting protrusion and the first limiting groove may be arranged on the fixing component 5, as long as the position locking of the fixing component 5 and the leveling base 2 can be achieved while realizing the detachable connection between the fixing component 5 and the leveling base 2.

[0062] According to an embodiment of the utility model, the first limiting protrusion and the first limiting groove are provided with a coaxially arranged through hole, and a fastener 202 is inserted into the through hole. In the embodiment of the utility model, the first limiting protrusion and the first limiting groove are provided with a coaxially arranged through hole, and the first limiting protrusion and the first limiting groove are fixed together by the fastener 202, that is, the positional relationship between the fixing component 5 and the leveling base 2 is fixed, which can prevent the positional relationship between the fixing component 5 and the leveling base 2 from changing under the influence of external factors, causing new errors and affecting subsequent angle calibration operations.

[0063] According to an embodiment of the utility model, a second limiting groove 5021 is provided on both the first slot 501 and the second slot 502, and the second limiting groove 5021 is suitable for fixing the ultrasonic probe 1. It should be noted that when the ultrasonic probe 1 is used for lumbar puncture positioning, a puncture frame positioning protrusion 103 is usually provided on the peripheral side of the head end of the ultrasonic probe 1. Therefore, when the ultrasonic probe 1 is calibrated by the ultrasonic probe calibration device in this embodiment, by setting the puncture frame positioning protrusion 103 in the second limiting groove 5021 in the first slot 501 or the second slot 502, the ultrasonic probe 1 can be prevented from moving or shaking during the calibration process, thereby ensuring the calibration accuracy of the angle sensor 101.

[0064] According to an embodiment of the present utility model, on the other hand, an ultrasound probe calibration system is provided, comprising: an ultrasound probe 1, the above-mentioned ultrasound probe calibration device, an operating handle and a display.

[0065] Specifically, an angle sensor 101 is provided inside the ultrasonic probe 1; the above-mentioned ultrasonic probe 1 calibration device is suitable for calibrating the angle sensor 101; the operating handle is connected to the angle sensor 101 by signal; and the display is connected to the angle sensor 101 by signal.

[0066] The embodiment of the utility model connects the angle sensor 101 in the ultrasonic probe 1 to the operating handle and the display signal respectively, so that when the angle sensor 101 is calibrated using the above-mentioned ultrasonic probe calibration device, the angle information of the angle sensor 101 can be fed back to the display in real time, and then the operator can make corresponding operations on the angle sensor 101 through the operating handle according to the information fed back by the angle sensor 101 on the display.

[0067] According to one embodiment of the utility model, the ultrasound probe calibration system also includes an ultrasound probe host, which is respectively connected to the operating handle and the display signal. A fixed bracket 6 is also provided on one side of the ultrasound probe host, and a horizontal detection device 201 is provided on the fixed bracket 6 and a third slot 601 is provided on the side away from the ultrasound probe host. The ultrasound probe 1 is suitable for being clamped in the fixed bracket 6 through the third slot 601, and the head end of the ultrasound probe 1 extends out of the third slot 601.

[0068] The embodiment of the utility model can ensure that the fixed bracket 6 always maintains a horizontal state on the ultrasonic probe host by setting a horizontal detection device 201 on the fixed bracket 6, so that after the ultrasonic probe 1 is set on the fixed bracket 6 through the third slot 601, the angle sensor 101 in the ultrasonic probe 1 can be calibrated by utilizing the structure of the ultrasonic probe host itself.

[0069] According to an embodiment of the utility model, the outer periphery of the ultrasonic probe 1 is provided with a guide protrusion 102 arranged along the length direction of the ultrasonic probe 1, and the third slot 601 is provided with a guide groove matched with the guide protrusion 102. In the embodiment of the utility model, by providing the guide protrusion 102 arranged along the length direction of the ultrasonic probe 1 on the outer periphery of the ultrasonic probe, and then providing the guide groove matched with the guide protrusion 102 in the third slot 601 of the fixed bracket 6, it is possible to ensure that the ultrasonic probe 1 remains in a vertical state in the horizontally arranged fixed bracket 6, thereby ensuring the accuracy of the subsequent calibration of the angle sensor 101.

[0070] The process of the embodiment of the present invention for calibrating the angle sensor 101 in the ultrasonic probe 1 by means of the fixed bracket 6 is as follows:

[0071] like Figure 5 As shown, the fixed bracket 6 is horizontally set on one side of the ultrasonic probe main unit through the horizontal detection device 201, and then the guide protrusion 102 on the ultrasonic probe 1 is set in the guide groove in the third slot 601, so that the ultrasonic probe 1 is vertically set on the fixed bracket 6. At this time, if it is found through the display that the angle of the angle sensor 101 on the X-axis and the Y-axis is not zero, the X-axis and the Y-axis of the angle sensor 101 can be zeroed and calibrated by the control handle.

[0072] According to one embodiment of the utility model, the ultrasonic probe 1 includes a piezoelectric layer and a backing layer 104 and a shell located around the piezoelectric layer and the backing layer 104; the angle sensor 101 is arranged at one end of the backing layer 104 away from the piezoelectric layer or on the inner side of the shell through a PCB board 1041.

[0073] The angle sensor 101 of the embodiment of the utility model is arranged on the backing layer 104 or the shell through the PCB board 1041, which can fix the position of the angle sensor 101 in the ultrasonic probe 1, and can make the angle sensor 101 and the head end of the ultrasonic probe 1 have a certain orientation and coordinate relationship, thereby ensuring the accuracy of subsequent angle information.

[0074] It should be noted that the PCB board 1041 can be fixed to the backing layer 104 or the housing by gluing or screwing, as long as the PCB board 1041 can be firmly fixed to the backing layer 104 or the housing, and no limitation is made here.

[0075] In one example, if Figure 6 As shown, the PCB board 1041 is fixed to the backing layer 104 by screwing. Compared with gluing, screwing can ensure better connection strength and is conducive to later replacement or maintenance.

[0076] In another example, a heat conductor is provided at one end of the backing layer 104 away from the piezoelectric layer, and the PCB board 1041 is arranged on the backing layer 104 through the heat conductor. It can be understood that the temperature of the backing layer 104 can be reduced by providing the heat conductor, so that it is always within the normal operating temperature range.

[0077] According to an embodiment of the present invention, an angle control unit is further provided in the ultrasonic probe 1 , and the angle control unit is connected to the angle sensor 101 and the ultrasonic probe host, respectively.

[0078] The embodiment of the utility model can monitor the angle information of the angle sensor 101 in real time by setting an angle control unit in the ultrasonic probe 1. When the angle information of the angle sensor 101 remains unchanged for a long time, the angle control unit can transmit this information to the ultrasonic probe host, and then the ultrasonic probe host will stop supplying power to the ultrasonic probe 1, so as to avoid damage to the ultrasonic probe 1 when it is powered on for a long time.
