Referring to fig. 1, the housing 10 may include a probe handle case 11, a probe acoustic window 12, and a base 13. In some embodiments, the probe handle case 11 and the probe acoustic window 12 are connected to form a receiving cavity 101. The base 13 is disposed within the accommodation chamber 101 to divide the accommodation chamber 101 into an accommodation chamber 102 and a liquid chamber 103. The receiving chamber 102 is for receiving the driving assembly 20. The liquid chamber 103 is used to accommodate the ultrasonic transducer 30 and a liquid such as a coupling liquid. In addition, the driving assembly 20 may be partially disposed in the liquid chamber 103 and drivingly connected to the ultrasonic transducer 30.

The probe acoustic window 12 may be made of a rigid material. In some embodiments, a transparent material may be used, and other materials may be used, which are not described in detail. Of course, the material of the probe acoustic window 12 can be adjusted according to the needs of the volume probe 100. The probe acoustic window 12 may be tubular or cylindrical in shape as a whole, but may have other structures. The probe acoustic window 12 may be a shell-shaped structure, and a liquid chamber 103 is disposed inside the probe acoustic window and may be matched with the probe handle shell 11 to accommodate the base 13, the driving assembly 20, the ultrasonic transducer 30, and other structures.

Of course, the matching and connection mode of the probe handle shell 11 and the probe acoustic window 12 is not limited to screw connection, but may be bonding, clamping, plugging, welding, etc. In one embodiment, the probe handle shell 11 is of unitary construction with the probe acoustic window 12.

Referring to fig. 1, the base 13 may be disposed in the accommodating chamber 101. In some embodiments, the base 13 may be connected to the probe handle case 11 or the probe acoustic window 12 by screwing, bonding, clipping, plugging, welding, etc. to divide the receiving cavity 101 into the receiving cavity 102 and the liquid cavity 103. In some embodiments, the base 13 may also be connected to the probe handle shell 11 to form a receiving chamber 102.

The base 13 provides a mounting bracket 131 within the receiving chamber 102 for mounting the drive assembly 20. In some embodiments, the mounting bracket 131 may be made of a rigid material, may have a frame structure, and may have other structures.

A boot bracket 132 is provided on the base 13, such as on the mounting bracket 131, to facilitate mounting on or to other structures. In some embodiments, the boot carrier 132 may be coupled to the probe handle shell 11. In some embodiments, the boot mount 132 may be partially located within the receiving chamber 102. In some embodiments, boot bracket 132 may not be disposed on base 13, such as mounting bracket 131. In some embodiments, boot support 132 is used to route electrical traces.

A pivot assembly 133 is provided on the base 13 to facilitate mounting of the ultrasonic transducer 30. A rotation assembly 133 may be located within the liquid chamber 103. In some embodiments, the rotation assembly 133 may include a bearing.

Referring to fig. 1 and 2, fig. 2 is a partial schematic structural view of the volume probe 100 in the embodiment shown in fig. 1. The base 13 may be provided with a liquid outlet 134 in communication with the liquid chamber 103, such as to couple liquid flow into or out of the liquid chamber 103, to regulate the pressure within the liquid chamber 103. The base 13 may be provided with a liquid inlet 135 in communication with the liquid chamber 103 for filling the liquid chamber 103 with a liquid, such as a coupling liquid, through the liquid inlet 135.

It will be appreciated that in some scenarios, the base 13 may not be part of the housing 10.

Referring to fig. 1 and 2, the driving assembly 20 may include a driving member 21 fixed to the base 13, such as a mounting bracket 131, and a driving head 22 mounted on a driving shaft of the driving member 21. The driving shaft of the driving member 21 can be connected with the base 13 in a sealing manner, so that the driving shaft is partially positioned in the liquid chamber 103 and is fixedly connected with the driving head 22, and partially positioned in the accommodating chamber 102. The drive head 22 is located in the liquid chamber 103 and is mounted on the drive shaft of the drive member 21 so as to rotate together with the drive shaft of the drive member 21 and move on a circular trajectory under the drive of the drive member 21. The driving head 22 is in transmission connection with the ultrasonic transducer 30 to drive the ultrasonic transducer 30 to move.

In some embodiments, the drive 21 may be a motor, such as a stepper motor.

Referring to fig. 1, an ultrasonic transducer 30 may include a mounting bracket 31 rotatably coupled to a base 13, such as a pivot assembly 133, and a transducer body 32 mounted on the mounting bracket 31. The mounting bracket 31 cooperates with the rotation assembly 133 to effect rotation, e.g., reciprocation at a rotation angle, relative to the base 13. The mounting bracket 31 may be drivingly connected to a drive assembly 20, such as a drive head 22, to effect rotation of the mounting bracket 31 relative to the base 13. The transducer body 32 is mounted on the mounting bracket 31 for scanning detection.

Referring to fig. 1 and 3, fig. 3 is a schematic structural diagram of the mounting bracket 31 according to the embodiment shown in fig. 1 of the present application. The mounting bracket 31 is provided with a first rotating shaft 311 rotatably connected to the rotating assembly 133 to rotate around the first rotating shaft 311 under the driving of the driving assembly 20, such as the driving head 22, for reciprocating motion.

The mounting bracket 31 is provided with a slide slot 312 for slidably coupling with the drive assembly 20, such as the drive head 22. Thereby, when the driving assembly 20, for example, the driving head 22, moves on the circular track, the driving assembly slides on the sliding groove 312, and further, the rotation transmission is converted into the linear transmission, so that the mounting bracket 31 moves in the direction perpendicular to the axial direction of the first rotating shaft 311. In some embodiments, the sliding groove 312 may extend in the same axial direction as the first rotating shaft 311.

Referring to fig. 1 and 2, the volume probe 100 further includes a hose 40 connected to the base 13 and in communication with the outlet 134. The hose 40 is used for returning liquid, such as coupling liquid, into the liquid chamber 103 by a volume change when the liquid, such as the coupling liquid, in the liquid chamber 103 shrinks, so as to adjust the pressure in the liquid chamber 103. The hose 40 is used to regulate the pressure in the liquid chamber 103 by undergoing a volume change to accommodate the liquid, e.g., coupling liquid, flowing from the liquid chamber 103 when the liquid, e.g., coupling liquid, in the liquid chamber 103 thermally expands.

Referring to fig. 1 and 2, the volume probe 100 further comprises a loading port plug 50 for plugging the loading port 135. In some embodiments, the inlet plug 50 may be tethered to the base 13 by a cord, connector, or the like to prevent loss of the inlet plug 50.

The hose 40 may be sealed by heat-sealing to form a sealed end 43. In some embodiments, the second end 42 of the hose 40 may be blown and melted using a heat gun and then the second end 42 may be clamped with a tool to fuse and seal the walls of the tube to form the closed end 43. In some embodiments, the second end 42 of the hose 40 may be directly clamped together or the second end 42 of the hose 40 may be clamped together after being folded, and then the wall of the second end 42 of the hose 40 may be thermally fused and sealed by using a heat gun to form the blocking end 43. Of course, the hose 40 may be heated by other methods than by a heat gun, such as ultrasonic heating, friction heating, etc.

Before the hose 40 is sealed, a hot melt 44 may be placed on the second end 42 of the hose 40, and then the tube wall and the hot melt 44 are hot-melted and sealed by the heating method exemplified in the above embodiments to form a sealed end 43.

It is understood that the hot melt 44 in the above embodiment may be replaced by a plug, and the tube wall and the plug are hot-melted and sealed by the heating method in the above embodiment to form the blocking end 43.

Referring to fig. 17, 18 and 19, fig. 17 is a schematic cross-sectional view of the hose 40 at line a-a in the embodiment of fig. 4 of the present application, fig. 18 is a schematic cross-sectional view of the hose 40 in the embodiment of fig. 17 of the present application in another embodiment, and fig. 19 is a schematic cross-sectional view of the hose 40 in the embodiment of fig. 17 of the present application in yet another embodiment. The cross-sectional inner contour of the hose 40 in the middle between the two ends satisfies: the curvature radius of each point of the inner contour of the section is larger at least at one part of points than at least at another part of points.

Those skilled in the art will appreciate that the radii of curvature at each point on the circular profile are equal. In the present embodiment, the curvature radius of at least some points of the inner contour of the cross section of the middle portion of the hose 40 is not equal, and the curvature radius of at least some points is larger than the curvature radius of at least other points.

In the present embodiment, the "inner cross-sectional contour" refers to a contour on the inner side of a cross-section perpendicular to the axis of the hose 40 and defining the inner cavity (lumen) of the hose 40, and the "outer cross-sectional contour" refers to a contour on the outer side of the cross-section.

Referring to fig. 17, the cross-sectional inner contour of the middle portion of the hose 40 may be an oval shape. In other embodiments, the cross-sectional inner contour of the middle portion of the hose 40 may have several other shapes. For example, referring to FIG. 18, the cross-sectional inner profile of the middle portion of the hose 40 may be "oblong". For example, referring to fig. 19, the cross-sectional inner profile of the middle portion of the hose 40 may be "hyperbolic".

It will be appreciated that the cross-sectional inner profile of the central portion of the hose 40 may also be any other non-circular shape, as long as the area enclosed by the inner profile can be increased by deforming the inner profile without stretching the wall of the hose.

When the cross-sectional inner contour of the middle portion of the hose 40 is a non-circular contour, the area enclosed by the cross-sectional inner contour in the natural state is denoted as S1, the area enclosed by the cross-sectional inner contour in the operating state is denoted as S2, and the area enclosed by the cross-sectional inner contour when the cross-sectional inner contour becomes circular and the circumferential length of the tube wall thereof is constant is denoted as S3.

S1 and S2 can be made to always satisfy S1 < S2, so that the internal pressure of the hose 40 can be ensured to be always greater than the external pressure in the operating state.

Of course, S2 and S3 may be made to satisfy S2 < S3 at all times, so that the pressure inside the hose 40 in the working state is always lower than the pressure for deforming the tube wall into a circular shape, and thus the tube wall is not stretched, so that the pressure inside the hose 40 is lower than the pressure.

Of course, it is also possible to satisfy S1 < S2 < S3 at the same time.

In the present embodiment, the "operating state" of the hose 40 refers to a state in which the hose 40 is within its operating temperature range; the "natural state" refers to a state in which the coupling liquid is not injected before the volume probe 100 is assembled and the hose 40 is in a natural state, and the area enclosed by the inner contour of the cross section refers to the area of the cavity enclosed by the inner contour of the cross section.

In addition, for a section with a certain circumference of the pipe wall, the sectional area is the largest when the sectional shape is circular; when the shape is non-circular, the cross-sectional area is determined by the specific shape, the minimum approaches to 0, and the maximum approaches to the area when the shape is circular, and the change is very obvious. The area is changed from the minimum to the maximum, the perimeter is not changed, and the change of the area can be realized only by the change of the shape.

Thus, S2 is constantly greater than S1 and/or S2 is constantly less than S3. Since S2 is constantly larger than S1, the internal pressure of the hose 40 is always larger than the external pressure in the working state, so that external air can be prevented from entering the closed space; since S2 is constantly smaller than S3, the hose 40 always works with a non-circular cross-sectional inner contour, the wall of the hose is not stretched, and the pressure in the enclosed space is small.

In some embodiments, the liquid, such as a coupling liquid, changes volume only under the influence of temperature. Therefore, in the above embodiment, when the hose 40 is installed, and the coupling liquid such as the coupling liquid is injected and sealed, the initial pressure of the coupling liquid in the liquid chamber 103 and the hose 40 is adjusted (i.e. the initial magnitude of S2 is adjusted) reasonably, so that when the lowest working temperature of the hose 40 is the lowest, the coupling liquid volume is the smallest, and S2 is also the smallest, S2 is still greater than S1, and when the highest working temperature of the hose 40 is the highest, the coupling liquid volume is the largest, and S2 is also the largest, S2 is still less than S3, so that S2 is constantly greater than S1 and less than S3 in the working state.

For the hose 40 which has not reached the state of the circular cross-section inner contour, the force required for such change is small, and the pressure generated to the internal liquid such as the coupling liquid is also small, and therefore, the force acting on the sealing structure and the connecting structure of the probe acoustic window 12 and the base 13 is small, thereby avoiding the problem that the sealing structure between the probe acoustic window 12 and the base 13 is easily broken due to the large pressure of the internal liquid such as the coupling liquid.

In the several embodiments provided in the present application, it should be understood that the disclosed method and apparatus may be implemented in other manners. For example, the above-described apparatus embodiments are merely illustrative, and for example, a division of a module or a unit is only one type of logical division, and other divisions may be realized in practice, for example, a plurality of units or components may be combined or integrated into another system, or some features may be omitted, or not executed.

The integrated unit can be realized in a form of hardware, and can also be realized in a form of a software functional unit.
