[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. According to the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0027] In one aspect of the present application, an ultrasound probe is provided. Figure 1 and Figure 2 , Figure 1 is a schematic diagram of an embodiment of an ultrasound probe provided by the present application; Figure 2 yes Figure 1A schematic diagram of the cross-sectional structure of the ultrasonic probe along the AA direction. In one embodiment, the ultrasonic probe includes a housing 1 and a sound head assembly 2, a transmission rope 3, a first rope pulley 43, a driving member 41 and a transmission member 42 contained in the housing 1. The sound head assembly 2 includes a mounting bracket 21 and a transducer 22 fixed to the mounting bracket 21, and the mounting bracket 21 is rotatably mounted in the housing 1, wherein the driving member 41 is connected to the transmission member 42, the transmission member 42 is connected to the first rope pulley 43, the transmission rope 3 is wound around the first rope pulley 43 and fixed on the mounting bracket 21, the driving member 41 drives the transmission member 42 to rotate, the transmission member 42 drives the first rope pulley 43 to rotate, and drives the mounting bracket 21 and the transducer 22 to rotate through the transmission rope 3, at this time, the entire ultrasonic probe has a larger transmission ratio, so that while achieving the same transmission effect, the mass inside the entire ultrasonic probe is reduced and the driving force required for the ultrasonic probe as a whole is reduced, so that the requirements for the driving member 41 can also be reduced, making it easier to operate.

[0028] Specifically, the transmission member 42 includes a first transmission wheel 421 and a second transmission wheel 422, wherein the first transmission wheel 421 is connected to the driving member 41, and the second transmission wheel 422 is transmission-connected to the first transmission wheel 421 and the first rope wheel 43. The transmission member 42 uses a wheel transmission, which has a relatively simple structure and can transmit the driving force provided by the driving member 41 relatively smoothly.

[0029] Please continue to refer to Figure 2 More specifically, the driving member 41 includes a power body 411 and a driving shaft 410 connected to the power body 411. The transmission member 42 also includes a rotating shaft 423 disposed in the housing 1, and the second transmission wheel 422 and the first rope wheel 43 are both fixedly disposed on the rotating shaft 423, so that the second transmission wheel 422 and the first rope wheel 43 can rotate together under the drive of the driving member 41, thereby ensuring the maximization of the transmission efficiency. The first transmission wheel 421 is fixedly connected to the driving shaft 410, wherein the first transmission wheel 421 and the second transmission wheel 422 are both gears, and the first transmission wheel 421 and the second transmission wheel 422 are meshed with each other, so that the transmission member 42 can be transmitted at a relatively stable transmission ratio, and the transmission efficiency of the transmission member 42 is improved, so that when the same transmission effect is achieved, the requirements for the driving member 41 are simpler.

[0030] Furthermore, in some embodiments, the first transmission wheel 421 and the second transmission wheel 422 are both bevel gears, the axes of the first transmission wheel 421 and the second transmission wheel 422 are perpendicular to each other, and the first transmission wheel 421 and the second transmission wheel 422 are meshed with each other, so that the transmission element 42 is designed more compactly in the ultrasound probe while ensuring the transmission effect, and the space occupied is reduced, which is more conducive to reducing the size of the ultrasound probe and making it easier to operate. Furthermore, the instantaneous transmission ratio of the bevel gear is constant, and the working stability is high, which is more conducive to the ultrasound probe being able to scan the inside of the abdominal cavity smoothly and form a clearer image.

[0031] In other embodiments, the first transmission wheel 421 and the second transmission wheel 422 are both helical gears. The helical gears generate less noise during transmission, and when the gear module and gear width are the same, the effective tooth width of the helical gears is larger, and the helical gears have a stronger load-bearing capacity than spur gears.

[0032] It is understandable that both the first transmission wheel 421 and the second transmission wheel 422 can be plastic gears. Plastic gears are lighter in material, which is more conducive to reducing the mass of the ultrasound probe. When they are meshed and driven, they generate less noise and have a better shock-absorbing and noise-reducing effect. Furthermore, plastic gears have a higher degree of design freedom, which to a certain extent breaks through the design limitations of metal gears, shortens the production process and reduces manufacturing costs.

[0033] While ensuring that the transducer 22 can rotate flexibly, it is more convenient for the operator to hold it for operation. The driving member 41 and the transmission member 42 can be arranged more flexibly. In some embodiments, the rotation axis of the rotating shaft 423 is parallel to the rotation axis of the mounting bracket 21, such as Figure 2 The X direction described in the figure makes it possible for the second transmission wheel 422 and the first rope wheel 43 to smoothly drive the mounting bracket 21 to rotate through the transmission rope 3, thereby avoiding the transducer 22 from being unable to rotate normally in the housing 1 due to the different directions of the transmission force, thereby causing the ultrasonic probe to malfunction. Due to the demand for the drive member 41 and the size of the drive member 41, it often occupies a relatively large volume inside the entire ultrasonic probe housing 1. Therefore, in some application scenarios, the axis of the drive shaft 410 is perpendicular to the axis of rotation of the rotating shaft 423, that is, it is arranged along the length direction of the housing 1, wherein the length direction of the housing 1 is also Figure 2 The Y direction.

[0034] It is understandable that, in order to make the driving force direction provided by the driving member 41 consistent with the rotation direction of the transducer 22, the rotation axis of the driving shaft 410 is parallel to the rotation axis of the rotating shaft 423, which is also in the X direction, thereby reducing the driving force loss caused by the different directions of the force and reducing the demand for the driving member 41. Figure 2In some specific embodiments, when the first transmission wheel 421 and the second transmission wheel 422 are bevel gears meshing vertically with each other, the rotation axis of the drive shaft 410 is perpendicular to the rotation axis of the rotating shaft 423, so that the driving force of the driving member 41 can be coaxially transmitted to the first transmission wheel 421, and under the meshing action of the gears, the second transmission wheel 422 is driven to transmit, thereby driving the transducer 22 to rotate.

[0035] Under the action of the driving member 41, the first transmission wheel 421 and the second transmission wheel 422 mesh and rotate, the first rope wheel 43 rotates coaxially with the second transmission wheel 422, and driven by the transmission rope 3, they rotate together with the mounting bracket 21 and the transducer 22, thereby realizing multi-angle scanning of the abdominal cavity from outside the body, so that the user does not need to move the ultrasound probe multiple times at a high frequency when using the ultrasound probe, and can also perform a comprehensive scan.

[0036] Please refer to Figure 1 and Figure 3 , Figure 3 yes Figure 1 The schematic diagram of the structure of the internal structure of the shell of the ultrasonic probe described in the figure. The shell 1 includes a probe handle shell 11 and a probe acoustic window 12 connected to each other, one end of the probe handle shell 11 is an open end, and the end opposite to the open end is a sealed end. The sealed end is provided with a wire hole 110, and the outer wall of the probe handle shell 11 is also recessed to form a recessed portion, so that it is convenient to hold the probe handle shell 11 when in use. Among them, the probe handle shell 11 and the probe acoustic window 12 are surrounded to form an installation space 13, and the ultrasonic probe also includes a base 5, the base 5 is arranged in the shell 1, and the mounting bracket 21 is rotatably mounted on the base 5, that is, the base 5 is arranged in the installation space 13, and the installation space 13 is divided into an upper cavity 131 facing the probe acoustic window 12 and a lower cavity 132 away from the probe acoustic window 12, and the transducer 22 faces the probe acoustic window 12, and the ultrasonic wave emitted by the transducer 22 penetrates the surface of the human body through the probe acoustic window 12.

[0037] The base 5 separates the installation space 13, wherein the acoustic head assembly 2, the second transmission wheel 422, the first rope wheel 43 and the transmission rope 3 are all arranged in the upper cavity 131, and the driving member 41 is arranged in the lower cavity 132. The base 5 is also provided with a through hole 51, which passes through the upper cavity 131 and the lower cavity 132, connects the acoustic head assembly 2 with the driving member 41, and then drives the transducer 22 to rotate, so as to realize the normal operation of the ultrasonic probe. Among them, the first transmission wheel 421 is rotatably arranged on the base 5. The rotating shaft 423 is also rotatably arranged on the base 5, wherein, in some embodiments, the rotation axis of the rotating shaft 423 is perpendicular to the rotation axis of the first transmission wheel 421, and the rotation axis of the rotating shaft 423 is parallel to the rotation axis of the mounting bracket 21. At this time, the rotation directions of the rotating shaft 423 and the first transmission wheel 421 are perpendicular to each other. On the premise of ensuring the normal rotation of the transducer 22, the distance between the first transmission wheel 421 and the rotating shaft 423 along the probe acoustic window 12 to the probe handle shell 11 is reduced, and the vertical size of the ultrasonic probe is reduced, making it easier to hold and use. Furthermore, in order to protect the cable, a protective cover is connected to the wire hole 110. The material of the protective cover is a softer rubber material. The protective cover wraps the cable, thereby protecting the contact between the cable and the shell 1 from multiple bendings, which will cause the cable to break, further avoiding safety accidents of the ultrasonic probe.

[0038] Please continue to refer to Figure 2 and Figure 3 , the driving member 41 is arranged on the side of the base 5 facing away from the first transmission wheel 421. The first transmission wheel 421 is meshed with the second transmission wheel 422 in the upper cavity 131, and the driving force provided by the driving member 41 is transmitted to the second transmission wheel 422. The first transmission wheel 421 has a transmission shaft 4210, and the transmission shaft 4210 extends through the through hole into the lower cavity 132 and is connected to the driving member 41. Since a medical coupling agent is contained inside the ultrasonic probe, it is used to reduce the acoustic impedance difference between the ultrasonic probe and the skin and improve the image quality. A sealing sleeve 44 is sleeved on the transmission shaft 4210, and the transmission shaft 4210 is rotatably arranged on the through hole, and after passing through the through hole, it is connected to the driving shaft 410 through the coupling 412, which can effectively reduce and buffer the vibration generated by the driving member 41 during operation or reversing, so that the power output is more stable and reliable. The sealing sleeve 44 is located between the transmission shaft 4210 and the through hole, and is used to protect the medical coupling agent contained in the base 5 from leaking into the lower cavity 132 and thus affecting the normal operation of the driving member 41 .

[0039] More specifically, the second transmission wheel 422 is located below the mounting bracket 21, and a avoidance notch 4220 is provided at one end of the second transmission wheel 422 toward the mounting bracket 21. The setting of the avoidance notch 4220 further ensures that when the mounting bracket 21 rotates, there is sufficient rotation space inside the ultrasonic probe, and the distance from the highest point of the avoidance notch 4220 to the mounting bracket 21 is greater than the diameter of the second transmission wheel 422. On the premise of minimizing the size of the ultrasonic probe, the mounting bracket 21 is prevented from colliding with the second transmission wheel 422 when driving the transducer 22 to rotate, so that the transducer 22 cannot rotate to a corresponding angle.

[0040] Furthermore, in some other embodiments, the shape of the second transmission wheel 422 can be set to be fan-shaped or obtained by cutting half of a complete gear according to the actual rotation requirements of the transducer 22 of the ultrasonic probe. Under the premise of ensuring the normal operation of the second transmission wheel 422, the space occupied by the internal transmission parts 42 of the ultrasonic probe is further reduced, thereby reducing the size of the ultrasonic probe.

[0041] Furthermore, in other embodiments, when the required ultrasonic probe does not require additional control structure dimensions, that is, the internal space is large enough, the second transmission wheel 422 may also be a complete gear, that is, the avoidance notch 4220 may not be provided on the second transmission wheel 422 to ensure that the transducer 22 can rotate at a larger angle.

[0042] Please continue to refer to Figure 2 and Figure 3 The mounting bracket 21 is rotatably mounted on the base 5 by connecting the bearing 210. The acoustic head assembly 2 also includes a driven rope wheel 23 arranged on the mounting bracket 21, and the transmission rope 3 is fixed to the driven rope wheel 23, and the rotation axis of the driven rope wheel 23 is parallel to the rotation axis of the first rope wheel 43. Since the driven rope wheel 23 is fixedly mounted on the mounting bracket 21, its rotation direction is the same as that of the mounting bracket 21. Therefore, the driven rope wheel 23 is linked with the mounting bracket 21. When the transmission rope 3 drives the driven rope wheel 23 to rotate, the contact area with the driven rope wheel 23 is larger, which has a certain buffering effect on the traction force. Without affecting the normal operation of the transducer 22, the wheel arc of the driven rope wheel 23 can be used to provide a certain driving force, thereby reducing the workload of the driving member 41.

[0043] In order to prevent the driven rope pulley 23 from rotating at too large an angle and causing the edge of the driven rope pulley 23 to touch the second transmission wheel 422, thereby causing a rotation failure of the transducer 22, in some embodiments, a limiting structure (not shown) is provided on the mounting bracket 21. The limiting structure can be provided on the base 5 or near the connecting bearing 210, so as to prevent the mounting bracket 21 from rotating beyond the required amount, thereby preventing the transmission member 42 from causing a rotation failure of the transducer 22, and ensuring that the transducer 22 does not hit the edge of the transmission member 42, thereby causing damage to the transducer 22.

[0044] Since the transmission rope 3 is continuously subjected to tensile force when the transmission member 42 is transmitting, the transmission rope 3 needs to be kept taut to ensure the transmission accuracy. In addition, the transmission rope 3 is more likely to fail when the efficiency is high. In order to ensure the service life of the transmission member 42, please refer to Figure 4 , Figure 5 and Figure 6 , Figure 4 yes Figure 3 A schematic diagram of a partial connection structure between the first rope pulley and the elastic member; Figure 5 yes Figure 3 A schematic structural diagram of the elastic member described in; Figure 6 yes Figure 3 The schematic diagram of the structure of the acoustic head assembly and the transmission rope in the middle part. In some embodiments, the ultrasonic probe further includes an elastic member 6, and the elastic member 6 includes a fixing portion 61, a first connecting portion 62 and a second connecting portion 63, wherein the first connecting portion 62 and the second connecting portion 63 are respectively provided at opposite ends of the fixing portion 61. The fixing portion 61 is fixed to the first rope pulley 43 by bolts or other fixing members, and the two ends of the transmission rope 3 are respectively fixed to the first connecting portion 62 and the second connecting portion 63, and the transmission rope 3 is fixed to the two sides of the driven rope pulley 23, and is connected to the opposite sides of the first rope pulley 43 after being extended around the circumference of the driven rope pulley 23 from the two sides of the driven rope pulley 23 and crossed. When the transmission rope 3 is stretched, due to the deformation of the first connecting part 62 and the second connecting part 63, there is a tensile force on the transmission rope 3 to restore the deformation, so that the transmission rope 3 can continue to remain taut and continuously fit with the driven rope wheel 23 and the first rope wheel 43 for elastic compensation, thereby avoiding the transmission rope 3 from failing and deforming under the continuous taut state, causing looseness between the transmission rope 3 and the driven rope wheel 23 and the first rope wheel 43, resulting in reduced transmission efficiency.

[0045] Among them, the first connecting part 62 and the second connecting part 63 can be a hook, a knot or other similar structures, which are used to fix the transmission rope 3 to the elastic member 6 through the first connecting part 62 and the second connecting part 63 to prevent the transmission rope 3 from detaching from the elastic member 6 when it is subjected to tension, causing the transmission of the entire ultrasonic probe to fail and affecting the normal operation of the ultrasonic probe.

[0046] It is understandable that the elastic member 6 can be a spring, an elastic sheet, or other elastically deformable structures. Among them, the central axis of the first connecting portion 62 and the central axis of the second connecting portion 63 are colinear. The central axis introduced here can be a symmetry axis (for example, a centrally symmetrical symmetry axis, an axisymmetric symmetry axis), or an axis where the axis center is located. It is ensured that the elastic forces received by both ends of the elastic member 6 are balanced with each other, and it is avoided that when the entire transducer 22 rotates inside the probe acoustic window 12 due to uneven force at both ends of the elastic member 6, its rotation angle cannot reach the maximum rotatable angle, which reduces the scanning efficiency of the ultrasonic probe.

[0047] Furthermore, in order to enhance the service life of the transmission member 42, a gasket group 64 is included between the elastic member 6 and the bolt, which increases the contact area between the bolt and the elastic member 6, reduces the pressure of the bolt on the surface of the elastic member 6, and further ensures that the bolt tightly fixes the elastic member 6 and the first rope pulley 43.

[0048] In order to enable the driven rope wheel 23 to drive the mounting bracket 21 to swing, in some embodiments, the transmission rope 3 includes a first rope 31 and a second rope 32, one end of the first rope 31 is connected to the driven rope wheel 23, the other end is wound around the first rope wheel 43, and connected to the first connecting portion 62. One end of the second rope 32 is connected to the driven rope wheel 23, the other end is wound around the first rope wheel 43, and connected to the second connecting portion 63, and the first rope 31 and the second rope 32 are stretched on both sides of the first rope wheel 43 and the driven rope wheel 23, respectively, reducing the extension burden of the transmission rope 3 and ensuring the service life of the internal transmission part 42 of the ultrasonic probe. The first rope 31 and the second rope 32 cross each other at the part between the first rope wheel 43 and the driven rope wheel 23, so that the first rope wheel 43 drives the driven rope wheel 23 to rotate under the pulling of the first rope 31 and the second rope 32, thereby realizing the rotation of the transducer 22.

[0049] Furthermore, in order to ensure the relative fixation of the position between the transmission rope 3 and the first rope pulley 43 and the driven rope pulley 23, in some embodiments, the first rope pulley 43 and the driven rope pulley 23 are both provided with annular grooves 230 in the circumferential direction, and two annular grooves 230 are correspondingly provided. The first rope 31 and the second rope 32 are respectively accommodated in the annular grooves 230, thereby preventing the transmission rope 3 from detaching from the first rope pulley 43 and the driven rope pulley 23 due to excessive rotation speed when the transmission member 42 is transmitting, thereby causing the ultrasonic probe to malfunction.

[0050] Another aspect of the present application provides an ultrasonic imaging device, which includes an ultrasonic host and any of the above-mentioned ultrasonic probes, and the ultrasonic probe is connected to the ultrasonic host. Therefore, it also has all the beneficial effects of the above-mentioned ultrasonic probes, which will not be repeated here.
