Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a cavity volume probe and an ultrasonic testing device. Background Technology

[0002] The intracavitary volume probe is a type of volumetric ultrasound probe that can perform volumetric scanning of the ultrasound beam. It can be used in gynecological examinations, such as examinations of uterine and ovarian diseases, monitoring of follicle development, pelvic floor ultrasound, in vitro fertilization and embryo transfer, and other routine medical examinations and surgical procedures. Due to the special nature of the area to be examined and the limited operating space, and because the intracavitary volume probe has a larger, more complex, and heavier handheld structure compared to other B-mode ultrasound probes, doctors are prone to wrist fatigue during the examination. Furthermore, the intracavitary volume probe is generally designed in a rod shape, which makes it difficult to operate accurately in actual diagnostic procedures, especially when using it with a puncture frame attached, as it is difficult to precisely adjust the needle to the puncture site. Summary of the Invention

[0003] The main technical problem addressed in this application is how to achieve the bending and adjustment of the bending angle of the handle of the cavity volume probe, so as to reduce labor intensity, save manpower, and improve detection results.

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide a cavity volume probe. The cavity volume probe includes: a handle housing with a probe mounting portion, a grip portion, and a connecting portion connecting the probe mounting portion and the grip portion, the connecting portion being used to adjust the included angle between the probe mounting portion and the grip portion, wherein the included angle is an obtuse angle; a probe body fixedly connected to one end of the probe mounting portion away from the connecting portion; wherein the cavity volume probe further includes: a drive mechanism disposed within the handle housing; a transmission mechanism disposed within the handle housing, and the transmission mechanism being connected to both the probe body and the drive mechanism, the drive mechanism being used to drive the transmission mechanism to work, the transmission mechanism driving the probe body to move; wherein the transmission mechanism includes: a first-stage transmission mechanism and a second-stage transmission mechanism; the first-stage transmission mechanism is connected to the drive mechanism; the second-stage transmission mechanism is located between the probe body and the first-stage transmission mechanism and is connected to the probe body; the drive mechanism is used to drive the first-stage transmission mechanism to work, the first-stage transmission mechanism driving the second-stage transmission mechanism to work, the second-stage transmission mechanism driving the probe body to move; and a transmission belt is used to realize the second-stage transmission mechanism.

[0005] To address the aforementioned technical problems, another technical solution adopted in this application is to provide an ultrasonic testing device. This ultrasonic testing device includes a controller and the aforementioned cavity volume probe. The controller is connected to the cavity volume probe and is used to control the cavity volume to perform ultrasonic testing on the area to be tested.

[0006] The beneficial effects of this application's embodiments are as follows: The cavity volume probe of this application includes: a handle housing, which has a probe mounting part, a gripping part, and a connecting part connected between the probe connecting part and the gripping part. The connecting part is used to adjust the included angle between the probe mounting part and the gripping part, wherein the included angle is an obtuse angle; and a probe body, which is fixedly connected to the end of the probe mounting part away from the connecting part. In this way, the handle housing of the cavity volume probe of this application has a connecting part between the probe mounting part and the gripping part. The included angle between the probe mounting part and the gripping part of the handle housing can be adjusted through the connecting part. The probe mounting part of the handle housing is connected to the probe body, and the gripping part of the handle housing is the handheld end of the cavity volume probe.

[0031] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0032] This application first proposes a cavity volume probe, such as Figures 1 to 9 As shown, Figure 1 This is a three-dimensional structural schematic diagram of an embodiment of the cavity volume probe of this application; Figure 2 yes Figure 1 Schematic diagram of one side view of the cavity volume probe in the embodiment; Figure 3 yes Figure 2 Schematic diagram of the cavity volume probe in different adjustment states in the embodiment; Figure 4 yes Figure 1 Schematic diagram of one side view of the cavity volume probe in the embodiment; Figure 5 yes Figure 1 A partial cross-sectional view of the cavity volume probe along line A' in the embodiment; Figure 6 yes Figure 5 Schematic diagram of one side view of the cavity volume probe in the embodiment; Figure 7 yes Figure 5 Schematic diagram of one side view of the cavity volume probe in the embodiment;

[0033] Figure 8 yes Figure 5 An enlarged structural schematic diagram of region B in the cavity volume probe of the embodiment; Figure 9 yes Figure 5 An enlarged structural diagram of region C in the cavity volume probe of this embodiment. The cavity volume probe 10 of this embodiment includes: a handle housing 110 and a probe body 120; wherein, the handle housing 110 is provided with a probe mounting part 111, a grip part 112 and a connecting part 113 connected between the probe mounting part 111 and the grip part 112, the connecting part 113 is used to adjust the included angle between the probe mounting part 111 and the grip part 112, wherein the included angle is an obtuse angle; the probe body 120 is fixedly connected to the end of the probe mounting part 111 away from the connecting part 113.

[0034] The included angle α between the probe mounting part 111 and the grip part 112 of the handle housing 110 is the included angle α between the central axis of the probe mounting part 111 and the central axis of the grip part 112; since the probe body 120 is fixedly connected to the end of the probe mounting part 111 away from the connecting part 113, the included angle α is also the included angle α between the central axis of the probe body 120 and the central axis of the grip part 112 (handheld end).

[0035] During the use of the cavity volume probe 10, the user can adjust the bending angle, i.e. the included angle α, between the probe mounting part 111 and the grip part 112 of the handle housing 110 according to actual needs, so as to adjust the bending angle between the probe body 120 and the grip part 112, thereby improving the user's comfort and detection accuracy.

[0036] Unlike existing technologies, in this embodiment, the handle housing 110 of the cavity volume probe 10 has a connecting part 113 between the probe mounting part 111 and the grip part 112. The angle between the probe mounting part 111 and the grip part 112 can be adjusted via the connecting part 113. The probe mounting part 111 is connected to the probe body 120, and the grip part 112 serves as the handheld end of the cavity volume probe 10. Therefore, the angle between the probe body 120 and the handheld end can be adjusted via the connecting part 113, increasing the operating space at the handheld end, alleviating wrist fatigue, and improving operating accuracy. Thus, this embodiment enables adjustable bending angle of the handle of the cavity volume probe 10, thereby reducing labor intensity, saving manpower, and improving detection results.

[0037] The cavity volume probe 10 in this embodiment is a type of volume probe, which refers to an ultrasonic probe with three-dimensional imaging function. It has a transducer 122 inside for transmitting and receiving signals, and a power source driven by a motor 141. Under the signal control of the controller, the motor 141 drives the transducer 122 to swing back and forth within a certain angle range through a transmission mechanism. When scanning the human body, the transducer 122 can transmit ultrasonic signals and receive echo signals with human tissue information during each angular swing. The controller processes the echo information received by the probe to image the human tissue, thereby constructing a three-dimensional image of the human tissue.

[0038] Optionally, in this embodiment, the connecting part 113 and the probe mounting part 111 are integrally provided, and the angle between the end of the connecting part 113 near the holding part 112 and the end of the connecting part 113 near the probe mounting part 111 is adjusted to adjust the included angle α.

[0039] In this embodiment, the cavity volume probe 10 further includes a drive mechanism 114 and a transmission mechanism (not shown in the figure), both of which are disposed inside the handle housing 110. The transmission mechanism is connected to the probe body 120 and the drive mechanism 114 respectively. The drive mechanism 114 is used to drive the transmission mechanism to work, and the transmission mechanism drives the probe body 120 to move.

[0040] For ease of description, in this embodiment, the integrally formed connecting part 113 and probe mounting part 111 are referred to as the first housing; wherein, the drive mechanism 114 is disposed within the grip part 112, and the transmission mechanism is disposed within the first housing. In this embodiment, the handle housing 110 protects the internal structures such as the drive mechanism 114 and the transmission mechanism; and the handle housing 110 is realized by the first housing and the grip part 112, making the installation of the cavity volume probe 10 more convenient.

[0041] Furthermore, the grip portion 112 in this embodiment is also used to realize the handheld end of the cavity volume probe 10, and the first housing is also used to realize the connection between the grip portion 112 and the probe body 120.

[0042] Optionally, the transmission mechanism in this embodiment includes: a first-stage transmission mechanism 115 and a second-stage transmission mechanism 116; wherein, the first-stage transmission mechanism 115 is connected to the drive mechanism 114; the second-stage transmission mechanism 116 is located between the probe body 120 and the first-stage transmission mechanism 115, and is connected to the probe body 120; the drive mechanism 114 is used to drive the first-stage transmission mechanism 115 to work, the first-stage transmission mechanism 115 drives the second-stage transmission mechanism 116 to work, and the second-stage transmission mechanism 116 drives the probe body 120 to move.

[0043] As can be seen from the above analysis, the included angle α between the probe mounting part 111 and the grip part 112 can be adjusted by the connecting part 113. Therefore, this embodiment adopts a two-stage transmission mechanism, which can match the housing structure of the handle housing 110, avoid the influence of the bending angle of the handle housing 110 on the operation of the transmission mechanism, and thus avoid the influence of the bending angle of the handle housing 110 on the detection accuracy.

[0044] Optionally, in this embodiment, the probe mounting part 111, the connecting part 113, and the gripping part 112 are integrally arranged. The connecting part 113 is made of a deformable material, and the angle between the end of the connecting part 113 near the gripping part 112 and the end of the connecting part 113 near the probe mounting part 111 can be adjusted by the deformation of the material of the connecting part 113.

[0045] The deformable material in this embodiment is bendable, stretchable, and torsional, allowing the probe mounting part 111 and the gripping part 112 to be deformably connected. The deformable material can be a polymer material such as resin or fiber, or a flexible metal tube, etc.

[0046] To simplify the manufacturing process, the connecting part 113, the gripping part 112, and the probe mounting part 111 in this embodiment are integrally formed. Of course, in other embodiments, the connecting part may be set independently of the probe mounting part and / or the gripping part, and the probe mounting part, the gripping part, and the connecting part may be connected by means of adhesive bonding or screws.

[0047] When the bending angle of both ends of the handle housing 110 increases, one side of the connecting part 113 undergoes a certain elongation deformation, resulting in stretching, while the other side of the connecting part 113 undergoes compression deformation; when the two ends of the handle housing 110 are nearly parallel, one side of the connecting part 113 undergoes a certain compression deformation, resulting in compression, while the other side of the connecting part 113 undergoes stretching.

[0048] Optionally, the first-stage transmission mechanism 115 of this embodiment includes: a driving gear 151 and a driven gear 152; wherein, the driving gear 151 is connected to the drive mechanism 114; the driven gear 152 is meshed with the driving gear 151 and is connected to the second-stage transmission mechanism 116; the drive mechanism 114 drives the driving gear 151 to rotate, the driving gear 151 drives the driven gear 152 to rotate, and the driven gear 152 drives the second-stage transmission mechanism 116 to move.

[0049] The first-stage transmission mechanism 115 in this embodiment adopts a cylindrical gear transmission structure. Cylindrical gears have the advantages of reliable transmission operation, long service life, high transmission efficiency, compact structure and simple operation and maintenance.

[0050] In other embodiments, other transmission mechanisms can be used instead of the first-stage transmission mechanism 115 of this embodiment, such as pulley assemblies and transmission belts.

[0051] Optionally, the second-stage transmission mechanism 116 in this embodiment includes: a drive pulley 161 and a transmission belt 162; wherein, the drive pulley 161 is fixedly connected to the driven gear 152; one end of the transmission belt 162 is connected to the drive pulley 161, and the other end of the transmission belt 162 is connected to the probe body 120; the driven gear 152 drives the drive pulley 161 to rotate, the drive pulley 161 drives the transmission belt 162 to slide, and the transmission belt 162 drives the probe body 120 to move.

[0052] In this embodiment, the driving pulley 161 can be fixedly connected to the driven gear 152 via the connecting shaft 163, or the driving pulley 161 and the driven gear 152 can be integrated into one structure, so that the driving pulley 161 rotates as the driven gear 152 rotates.

[0053] In this embodiment, the transmission belt 162 is a steel wire rope or other non-elastic transmission belt; in this embodiment, the transmission belt 162 is used to realize the second-stage transmission mechanism 116, which can improve the flexibility of the bending angle adjustment of the handle 110.

[0054] As can be seen from the above analysis, during the use of the cavity volume probe 10, the angle α between the end of the handle housing 110 near the probe body 120 and the other end is adjustable. In this embodiment, the second-stage transmission mechanism 116 adopts an active pulley 161 and a transmission belt 162, so that the extension direction of the end of the transmission belt 162 connected to the probe body 120 changes with the end of the probe mounting part 111 near the probe body 120, so that the bending angle of the handle housing 110 is adjustable and does not affect the detection accuracy.

[0055] Optionally, the second-stage transmission mechanism 116 of this embodiment further includes: a first reversing wheel 164 and a second reversing wheel 165; wherein, the first reversing wheel 164 is disposed between the drive pulley 161 and the probe body 120; the second reversing wheel 165 is disposed between the first reversing wheel 164 and the probe body 120; the other end of the transmission belt 162 extends from the drive pulley 161 along the first reversing wheel 164 and the second reversing wheel 165 to the probe body 120, so that the end of the transmission belt 162 connected to the probe body 120 is parallel to the end of the probe mounting part 111 connected to the probe body 120.

[0056] In this embodiment, the first reversing wheel 164 and the second reversing wheel 165 are used to switch the transmission belt 162 from the radial direction of the driving pulley 161 to the parallel direction of the end where the probe mounting part 111 is connected to the probe body 120.

[0057] In this embodiment, the rotation surface of the active pulley 161 is perpendicular to the rotation surface of the first reversing wheel 164, and the rotation surface of the second reversing wheel 165 is parallel to the rotation surface of the first reversing wheel 164; the axial direction of the active pulley 161 is parallel to the central axis of the gripping part 112.

[0058] The axial direction of the drive pulley 161 is parallel to the central axis of the grip portion 112, which makes the axial direction of the drive gear 151 parallel to the central axis of the grip portion 112. This, in turn, makes the connecting shaft between the drive mechanism 114 and the drive gear 151 parallel to the central axis of the grip portion 112. This allows the drive mechanism 114 and the drive gear 151 to be arranged along the central axis of the grip portion 112, that is, along the length of the handle housing 110. Therefore, the radial dimension of the grip portion 112 can be reduced, making it easier for the user to hold.

[0059] Optionally, the second-stage transmission mechanism 116 of this embodiment further includes: a tensioning pulley 166 and a spring 167; wherein, the tensioning pulley 166 is located between the first reversing pulley 164 and the second reversing pulley 165, and the transmission belt 162 extends from the first reversing pulley 164 along the tensioning pulley 166 to the second reversing pulley 165 to increase the tension of the transmission belt 162; the spring 167 is arranged around the fixed shaft of the first reversing pulley 164, and one end abuts against the connecting part 113, and the other end abuts against the fixed shaft of the tensioning pulley 166 to generate an elastic torsional force, so that the transmission belt 162 is in a taut state.

[0060] In other embodiments, to simplify the structure, only a tensioning wheel may be provided; in other embodiments, other elastic elements may be used instead of springs.

[0061] The second-stage transmission mechanism 116 in this embodiment includes two first reversing pulleys 164, two second reversing pulleys 165, and two tensioning pulleys 166. The middle end (middle position) of the transmission belt 162 is connected to the drive pulley 161, and the two ends of the transmission belt 162 are connected to the probe body 120 through their respective first reversing pulleys 164, second reversing pulleys 165, and tensioning pulleys 166.

[0062] The middle end of the transmission belt 162 is connected to the drive pulley 161 to divide the transmission belt 162 into a first part and a second part. When the drive pulley 161 rotates counterclockwise, the length of the first part of the transmission belt 162 becomes shorter, while the length of the second part becomes longer, allowing the probe body 120 to move in the first direction. When the drive pulley 161 rotates clockwise, the length of the first part of the transmission belt 162 becomes longer, while the length of the second part becomes shorter, allowing the probe body 120 to move in the second direction. The first direction and the second direction are opposite, enabling the probe body 120 to swing back and forth. The probe body 120 is affected by the combined action of the first and second parts of the transmission belt 162, which increases the stability of the swing of the probe body 120 and thus improves the detection effect.

[0063] In other embodiments, the second-stage transmission mechanism may consist of only a first reversing wheel, a second reversing wheel, and a tensioning wheel. One end of the transmission belt is connected to the drive pulley, which retracts or extends the transmission belt when it rotates. The other end is connected to the probe body via the first reversing wheel, the second reversing wheel, and the tensioning wheel. When the drive pulley rotates counterclockwise, the transmission belt shortens (is shortened), allowing the probe body to move in the first direction. When the drive pulley rotates clockwise, the transmission belt lengthens (is extended), allowing the probe body to move in the second direction. The first and second directions are opposite, enabling the probe body to swing back and forth. Since only one first reversing wheel, one second reversing wheel, and one tensioning wheel are provided, the volume of the cavity volumetric probe can be reduced.

[0064] Optionally, the drive mechanism 114 in this embodiment includes a coupling 142 and a motor 141; wherein the coupling 142 is fixedly connected to the drive gear 151; the motor 141 is drively connected to the coupling 142; the motor 141 drives the coupling 142 to rotate, and the coupling 142 drives the drive gear 151 to rotate.

[0065] In this embodiment, a coupling 142 is used to realize the transmission connection between the motor 141 and the drive gear 151, which can improve power buffering, vibration reduction and improve the dynamic performance of the shaft system.

[0066] In this embodiment, the motor 141 can be a stepper motor; in other embodiments, a DC motor or the like can be used instead of a stepper motor, or a motor can be used to drive the drive gear directly.

[0067] Optionally, in this embodiment, the cavity volume probe 10 further includes a base 140, which is fixedly connected to the connecting part 113. A transmission mechanism is disposed on the first side of the base 140, and a drive mechanism 114 is disposed on the second side of the base 140. The first side and the second side of the base 140 are disposed opposite to each other, and the base 140 is disposed at the connection between the connecting part 113 and the gripping part 112.

[0068] Of course, in other embodiments, the base may also be fixedly connected to the gripping part, or the gripping part and the connecting part may be fixedly connected to the base respectively.

[0069] The probe body 120, the probe mounting part 111 and the connecting part 113 are filled with liquid for ultrasonic transmission coupling, and the liquid is separated from the drive mechanism 114 by the base 140.

[0070] Furthermore, the cavity volume probe 10 in this embodiment also includes a motor bracket (not shown in the figure), the motor 141 is mounted on the motor bracket, and the motor bracket is fixed on the second side of the base 140.

[0071] Furthermore, in this embodiment, the driven gear 152 is rotatably fixed on the first side of the base 140 via a connecting shaft (not shown in the figure); the driving gear 151 is connected to the coupling 142 via a connecting shaft (not shown in the figure), which passes through the base 140.

[0072] Furthermore, the cavity volume probe 10 in this embodiment also includes: a transmission bracket (not shown in the figure) and a reversing wheel bracket (not shown in the figure). The reversing wheel bracket is mounted on the transmission bracket via a reversing wheel base pin (not shown in the figure). The first reversing wheel 164 and the tensioning wheel 166 are respectively mounted and fixed on both sides of the reversing wheel bracket and can rotate freely. The second reversing wheel 165 is mounted on the reversing wheel bracket. The reversing wheel bracket is fixed on the first side of the base 140. One end of the spring 167 is limited to a protrusion on the first side of the base 140.

[0073] Optionally, the probe body 120 of this embodiment includes: a third housing 121, a transducer 122, a head assembly base 124, and a transducer base 123; wherein, the third housing 121 is provided with an acoustic window (not shown in the figure) and is fixedly connected to the probe mounting part 111; the transducer 122 is disposed in the third housing 121; the head assembly base 124 is disposed in the third housing 121; the transducer 122 is disposed on the transducer base 123, and the transducer base 123 is provided with a boss (not shown in the figure) and a groove (not shown in the figure), the transducer base 123 is rotatably disposed on the head assembly base 124 through the boss, and the other end of the transmission belt 162 is fixed in the groove of the transducer base 123.

[0074] As can be seen from the above analysis, the second-stage transmission mechanism 116 of this embodiment includes two first reversing pulleys 164, two second reversing pulleys 165, and two tensioning pulleys 166. The middle end of the transmission belt 162 is connected to the drive pulley 161, and the two ends of the transmission belt 162 are respectively connected to the probe body 120 through their respective first reversing pulleys 164, second reversing pulleys 165, and tensioning pulleys 166. Two grooves are provided on both sides of the transducer base 123, and the two ends of the transmission belt 162 are respectively wound and fixed in the grooves on both sides of the transducer base 123. The transducer 122 can be fixedly installed on the transducer base 123 with epoxy resin.

[0075] The probe body 120 in this embodiment also integrates components or devices such as a sound-absorbing back block, a matching layer, a crystal array, and connecting wires.

[0076] Optionally, the cavity volume probe 10 of this embodiment further includes a tail sleeve assembly 130, which is disposed at one end of the handle 110 away from the probe body 120. Specifically, the tail sleeve assembly 130 is fixedly connected to one end of the grip portion 112 away from the connecting portion 113. The tail sleeve assembly 130 is used to connect the cavity volume probe 10 to the controller, and can also be used to realize signal transmission between the transducer 122 and the controller.

[0077] Optionally, the included angle α between the two ends of the handle housing 110 in this embodiment is 135°-150°.

[0078] Under the control of the controller, the motor 141 generates power and drives the drive gear 151 to rotate through the coupling 142. The drive gear 151 transmits power to the driven gear 152 through meshing transmission. The driven gear 152 drives the drive pulley 161 to rotate. The drive gear 151 also drives the deceleration motion, further amplifying the power. The transmission belt 162, which is fixedly wound around the drive pulley 161, transmits the motion to the probe body 120 under the drive of the drive pulley 161 and guided by the first reversing wheel 164 and the second reversing wheel 165. The transducer base 123 swings back and forth under the drive of the transmission belt 162, enabling the transducer 122 to swing back and forth within a certain angle range, thereby realizing three-dimensional data acquisition. The controller realizes 3D imaging based on the three-dimensional data.

[0079] As clinical ultrasound research into puncture continues to deepen, more and more doctors are conducting clinical studies on three-dimensional puncture. Because the intracavitary volume probe can visualize the path or position of the puncture needle on three visual planes in real time, it is theoretically much safer than using a two-dimensional probe. Therefore, in response to the needs of clinical puncture and the special nature of the clinical environment, the application scope of the intracavitary volume probe has been further expanded. However, the current intracavitary volume probes are all straight-handle structures, which cannot be changed in actual clinical applications. Moreover, when used with a puncture frame, the surgical space is small and difficult to operate, which has certain limitations for transvaginal examination and puncture.

[0080] Therefore, this application further proposes another embodiment of the cavity volume probe, such as... Figures 10 to 12 , Figure 10 This is a three-dimensional structural schematic diagram of an embodiment of the cavity volume probe of this application; Figure 11 yes Figure 10 Schematic diagram of one side view of the cavity volume probe in the embodiment; Figure 12 yes Figure 11 Schematic diagram of the cavity volume probe in different adjustment states of the embodiment. The difference between the cavity volume probe 20 of this embodiment and the cavity volume probe 10 of the above embodiment is that the cavity volume probe 20 of this embodiment further includes: a support 210 and a needle 220. The support 210 is disposed on the outside of the first housing (the probe mounting part 111 and the connecting part 113 are integrally disposed), and the needle 220 is disposed inside the support 210.

[0081] Specifically, the outer side of the first housing corresponds to its bent outer side; the bracket 210 of this embodiment includes a mounting part and a positioning part for accommodating the needle 220; wherein, the positioning part is tubular, the needle 220 passes through the positioning part, and both ends extend out of the positioning part, so that one end near the probe body 120 can contact the part to be tested, and the other end can extend out of the cavity, which is convenient for the user to operate.

[0082] In this embodiment, the mounting part can be an arc-shaped fastening structure fixed to the positioning part. When installing the bracket 210, the arc-shaped fastening structure is directly fastened to the first housing, which is convenient for installation. Moreover, in the non-puncture detection, the bracket 210 can be directly removed without affecting the non-puncture detection effect. Of course, in other embodiments, the mounting part can also adopt other structures, such as a sliding snap-fit ​​structure.

[0083] To improve the stability of bracket 210 installation, at least two mounting points should be provided.

[0084] Furthermore, to achieve precise positioning of the stent 210 on the first housing, a notch positioning structure can be provided on the outside of the first housing. During clinical puncture, one end of the stent 210 is positioned and installed on the first housing through the notch positioning structure, and the other end is installed on the probe body 120. The needle 220 enters the stent 210 from one end of the stent 210 and exits from the other end of the stent 210, that is, it reaches the position directly above the acoustic window in the probe body 120 to achieve the puncture function.

[0085] As the included angle α between the two ends of the handle 110 decreases, the included angle β between the grip 112 and the bracket 210 and the needle 220 increases, thus increasing the space in which the user's hand can move when gripping the grip 112.

[0086] The other structures of the cavity volume probe 20 in this embodiment are similar to those of the cavity volume probe 10 described above, and will not be repeated here.

[0087] This application further proposes another embodiment of the cavity volume probe, such as... Figures 13 to 22 The above, Figure 13 This is a three-dimensional structural schematic diagram of an embodiment of the cavity volume probe of this application; Figure 14 yes Figure 13 Schematic diagram of one side view of the cavity volume probe in the embodiment; Figure 15 yes Figure 13 Schematic diagram of one side view of the cavity volume probe in the embodiment; Figure 16 yes Figure 14 An enlarged structural schematic diagram of region E in the cavity volume probe of the embodiment; Figure 17 yes Figure 13 Schematic diagram from top view of the cavity volume probe of the embodiment; Figure 18 yes Figure 13 A partial cross-sectional view along D-D' of the cavity volume probe of the embodiment; Figure 19 yes Figure 18 Schematic diagram from top view of the cavity volume probe of the embodiment; Figure 20 yes Figure 18 Schematic diagram of one side view of the cavity volume probe in the embodiment; Figure 21 yes Figure 18 Schematic diagram of the structure of the first and second housings in the cavity volume probe of the embodiment; Figure 22 yes Figure 21 A magnified structural diagram of region F in the embodiment. The difference between the cavity volume probe 30 in this embodiment and the cavity volume probe 10 in the above embodiment is that: in this embodiment, the connecting part 313 and the probe mounting part 311 are integrally set, while the holding part 312 and the connecting part 313 are separately set, and the included angle α is adjusted by adjusting the angle between the end of the holding part 312 and the connecting part 313 that is close to the probe mounting part 311.

[0088] Optionally, in this embodiment, the end of the connecting part 313 near the gripping part 312 is provided with a first adjustment mechanism (not shown in the figure), and the end of the gripping part 312 near the connecting part 313 is provided with a second adjustment mechanism (not shown in the figure). The first adjustment mechanism and the second adjustment mechanism cooperate to adjust the angle between the gripping part 312 and the end of the connecting part 313 near the probe mounting part 311.

[0089] In this embodiment, the first adjustment mechanism includes a groove 321 disposed on the side wall of the connecting part 313 near the gripping part 312, and the second adjustment mechanism includes a slide rail 331 disposed on the side wall of the gripping part 312 near the connecting part 313. When the included angle α is adjusted, the slide rail 331 slides in the groove 321.

[0090] In this embodiment, the first adjustment mechanism and the second adjustment mechanism are implemented through a slide groove and slide rail structure. In other embodiments, other first adjustment mechanisms and second adjustment mechanisms can be used to implement the first adjustment mechanism and the second adjustment mechanism of this embodiment, so as to achieve the adjustable angle between the end of the grip connection part and the end near the probe mounting part.

[0091] In this embodiment, the slide groove 321 is a "T"-shaped arc-shaped slide groove. In other embodiments, the slide groove can also be other structures, such as a straight arc-shaped slide groove. In other embodiments, miniature arc-shaped gear rack transmission, miniature slide rail transmission, and other mechanical structures can be used instead of the slide groove 321 and slide rail 331 of this embodiment.

[0092] In this embodiment, the end face of the grip portion 312 near the connecting portion 313 is arranged in a gradient, such that the end face of the grip portion 312 near the connecting portion 313 includes a first end face and a second end face arranged in a gradient. The slide rail 331 is disposed on the second end face and extends from the second end face to the first end face, with the first end face being disposed near the connecting portion 313 relative to the second end face. With this structure, the slide rail 331 can slide within the slide groove 321, that is, when adjusting the included angle, there is no contact between the connecting portion 313 and the grip portion 312, and the grip portion 312 can rotate relative to the connecting portion 313 within a certain angle range, allowing the user to find a suitable operating angle.

[0093] Furthermore, the slide rail 331 is provided with a clamping member 332 for fastening the slide rail 331 and the slide groove 321, which can improve the stability of the connection between the connecting part 313 and the gripping part 312. The clamping member 332 can be a tightening nut or the like.

[0094] Optionally, the adjustment part 310 of this embodiment further includes a groove (not shown) provided on the end face of the connecting part 313 near the gripping part 312 and a protrusion 333 provided on the end face of the gripping part 312 near the connecting part 313. The protrusion 333 is embedded in the groove and is rotatably connected to the connecting part 313 through the connecting shaft 334. When adjusting the included angle, the protrusion 333 rotates along the connecting shaft 334. With this structure, the flexibility of adjusting the included angle between the connecting part 313 and the gripping part 312 can be improved.

[0095] The groove 321 and the recess are located on opposite sides of the connecting part 313 (inner and outer sides of the handle bend), and the slide rail 331 and the protrusion 333 are located on opposite sides of the grip part 312 (inner and outer sides of the handle bend).

[0096] The second reversing wheel (not shown in the figure) of this embodiment is installed and positioned in the connecting part 313. The gripping part 312 can rotate relative to the connecting part 313 within a certain radius range, and the rotation center O is set on the connecting part 313. The first-stage transmission mechanism (not shown in the figure) is fixedly installed with the gripping part 312.

[0097] After the connecting part 313 and the gripping part 312 are installed, the gripping part 312 can rotate in a circular motion relative to the connecting part 313 within a certain angle range, with the rotation center "O" as the center. When the clinician rotates to the desired position, the clinician can tighten the nut on the gripping part 312 to lock it, thereby fixing the slide rail 331 in the "T"-shaped arc-shaped slide groove 321.

[0098] The other structures of the connecting part 313 in this embodiment are similar to those of the first housing described above, and will not be described in detail here; the other structures of the gripping part 312 in this embodiment are similar to those of the second housing 330 described above, and will not be described in detail here; the other structures of the cavity volume probe 30 in this embodiment are similar to those of the cavity volume probe 10 described above, and will not be described in detail here.

[0099] In this embodiment, the active pulleys of the first-stage transmission mechanism and the second transmission mechanism are fixed to the grip (handheld end of the handle housing) via a base. When the grip is bent relative to the connecting part (connected to the probe body), the first-stage transmission mechanism and the base rotate synchronously, and the reversing wheel is fixed relative to the connecting part. When the user adjusts the position of the grip according to the actual clinical situation, the transmission direction of the transmission belt is fixed. That is, when the user needs to adjust the grip and the connecting part to various angles, it will not affect the transmission direction of the transmission belt. When the user adjusts the angle, the tension wheel in the second transmission mechanism will adjust with the change of angle to keep the transmission belt taut at all times.

[0100] In other embodiments, the first-stage transmission mechanism and the second-stage transmission mechanism may also be implemented by one or more combinations of planetary gear transmission mechanism, bevel gear transmission mechanism and rope wheel transmission mechanism.

[0101] This application further proposes an ultrasonic testing device, such as... Figure 23 As shown, Figure 23 This is a schematic diagram of an embodiment of the ultrasonic testing device of this application. The ultrasonic testing device of this embodiment includes a controller 1111 and a cavity volume probe 1112. The controller 1111 is connected to the cavity volume probe 1112 and is used to control the cavity volume probe 1112 to perform ultrasonic testing on the part to be tested.

[0102] The controller 1111 in this embodiment can be a control chip or a terminal, etc. The controller 1111 can be connected to the cavity volume probe 1112 via wired or wireless means.

[0103] The cavity volume probe 1112 is similar to the cavity volume probe described above, and will not be described in detail here.

[0104] In other embodiments, the controller may also be integrated into the cavity volume probe.

[0105] Unlike existing technologies, the cavity volume probe of this application includes: a handle housing with a probe mounting portion, a grip portion, and a connecting portion connecting the probe mounting portion and the grip portion. The connecting portion is used to adjust the angle between the probe mounting portion and the grip portion, wherein the angle is an obtuse angle; and a probe body, which is fixedly connected to the end of the probe mounting portion away from the connecting portion. In this way, the handle housing of the cavity volume probe of this application has a connecting portion between the probe mounting portion and the grip portion. The angle between the probe mounting portion and the grip portion can be adjusted through the connecting portion. Since the probe mounting portion of the handle housing is connected to the probe body, and the grip portion of the handle housing is the handheld end of the cavity volume probe, the angle between the probe body and the handheld end can be adjusted through the connecting portion, which increases the operating space of the handheld end, reduces wrist fatigue, and improves operating accuracy. Therefore, this application can achieve adjustable bending angle of the cavity volume probe handle, thereby reducing labor intensity, saving manpower, and improving detection results.

[0106] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
