As the wireless communication module is arranged in the probe, information interaction with the ultrasonic host can be carried out through the wireless communication module, and no signal line is needed between the probe in the ultrasonic cavity and the ultrasonic host. In addition, the probe in the ultrasonic cavity comprises a power supply module, and the power supply module supplies power to the driving mechanism and the wireless communication module, so that the probe can work normally.

Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a wireless ultrasonic intracavity probe. Background Art

[0002] The 360° ultrasonic intracavitary probe includes a reciprocating rotary transducer. During a rotational examination, the transducer can rotate more than 180° in a single direction. This large reciprocating angle enables the acquisition of images over a wider range during ultrasound testing. When performing an ultrasound pelvic floor examination using a 360° probe, doctors typically hold the probe handle by hand, causing the cable to bend and sag, making probe operation inconvenient. Furthermore, during a pelvic floor examination, doctors often need to hold the probe still for extended periods to capture images, and the force exerted by the bent and drooping cable can exacerbate wrist pain.

DETAILED DESCRIPTION

[0048] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings.

In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood.

[0050] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0051] In response to the problem that the current 360 ultrasonic intracavitary probe is inconvenient to operate when connected to the ultrasonic host via a cable, the rotary transducer in this application exchanges information with the ultrasonic host through a wireless module and is powered by a built-in power module. No cable is required between the ultrasonic intracavitary probe and the ultrasonic host, making the operation of the 360 ​​ultrasonic intracavitary probe convenient.

[0052] In one embodiment, please refer to Figure 1 and Figure 2 The ultrasonic intracavitary probe includes a handle housing 1, an intracavitary housing 2, and a rotary transducer 3 disposed within the intracavitary housing 2. The rotary transducer 3 rotates in a single direction at an angle greater than or equal to 180° during a scanning inspection. Thus, when the rotary transducer 3 reciprocates, the sum of the rotation angles during one reciprocating motion cycle is no less than 360°. In one embodiment, the rotary transducer 3 can also rotate in a single direction at an angle greater than or equal to 360° during a scanning inspection.

[0053] The handle shell 1 is for an operator to hold the ultrasonic intracavitary probe. The proximal end of the intracavitary shell 2 is connected to the distal end of the handle shell 1. The intracavitary shell 2 is used to extend into the patient's cavity.

[0054] The ultrasonic intracavitary probe also includes a main shaft 4 and a transducer drive mechanism 5. At least a portion of the main shaft 4 is located within the intracavitary housing 2. The rotary transducer 3 is mounted on the main shaft 4 so that the main shaft 4 drives the rotary transducer 3 to rotate about the axis of the main shaft 4. The transducer drive mechanism 5 is in driving connection with the main shaft 4 to drive the main shaft 4 to rotate. The transducer drive mechanism 5 can drive the main shaft 4 to rotate in both forward and reverse directions.

[0055] Please refer to Figure 2The ultrasonic intracavitary probe further includes a control module 6, a wireless communication module 7, and a power supply module 8. The control module 6 is connected to the transducer drive mechanism 5 to control the transducer drive mechanism 5. The wireless communication module 7 is used to communicate with the ultrasound host. The wireless communication module 7 is also connected to the rotational transducer 3 to transmit detection data of the rotational transducer 3 to the ultrasound host. The power supply module 8 is conductively connected to the wireless communication module 7 to supply power to the wireless communication module 7. The power supply module 8 is also conductively connected to the transducer drive mechanism 5 to supply power to the wireless communication module 7.

[0056] The wireless communication module 7 and the rotating transducer 3 can be communicated and connected directly through a wire or through other processing modules. For example, in one embodiment, the wireless communication module 7 is communicated and connected to the rotating transducer 3 through the information processing module 9. The information of the rotating transducer 3 is transmitted to the information processing module 9 for processing and then transmitted to the wireless communication module 7.

[0057] Similarly, in one embodiment, the wireless communication module 7 is communicatively connected to the control module 6 so that external control instructions can be transmitted to the control module 6 via the wireless communication module 7. Of course, as needed, the wireless communication module 7 can also transmit information sent externally by the control module 6. The wireless communication module 7 and the control module 6 can be directly connected or communicated through the information processing module 9.

[0058] In one embodiment, the wireless communication module 7 and the information processing module 9 work together to realize information interaction between the ultrasound intracavity probe and the ultrasound host.

[0059] It should be noted that in this application, the proximal and distal ends are distinguished based on the distance from the operator of the ultrasound intracavitary probe. The proximal end is the end closer to the operator, and the distal end is the end farther from the operator. For example, of the two ends of the intracavitary housing 2, the proximal end of the intracavitary housing 2 is closer to the operator, and the distal end is farther from the operator.

[0060] Because the probe has a built-in wireless communication module 7, it can exchange information with the ultrasound host through the wireless communication module 7, eliminating the need for signal cables between the intracavity probe and the ultrasound host. Furthermore, the intracavity probe includes a power supply module 8, which supplies power to the transducer drive mechanism 5 and the wireless communication module 7, enabling the probe to operate normally. Because the intracavity probe and the ultrasound host do not use cables for information exchange and power supply, the intracavity probe is more flexible and convenient to operate.

[0061] Further, in one embodiment, please refer to Figure 2The power module 8 is arranged at the proximal end of the handle housing 1. This allows for a more centralized arrangement of the other modules within the ultrasound intracavity probe, facilitating connections between the internal modules. In other embodiments, the power module 8 may also be arranged in the middle or distal end of the handle housing 1, depending on actual needs.

[0062] Specifically, in one embodiment, please refer to Figure 2 The transducer driving mechanism 5 includes a driving motor 51, which is close to the distal end of the handle housing 1 and away from the proximal end of the handle housing 1, and the power module 8 is close to the proximal end of the handle housing 1 and away from the distal end of the handle housing 1.

[0063] Please refer to Figure 2 and Figure 3 The drive motor 51 is connected to the main shaft 4 via a belt transmission mechanism. The belt transmission mechanism includes a drive wheel 52 connected to the drive motor 51 and a transmission wheel 53 fixed to the main shaft 4. The belt transmission mechanism also includes a transmission belt 54 connecting the drive wheel 52 and the transmission wheel 53. After the drive motor 51 starts to rotate, it drives the drive wheel 52 to rotate. The drive wheel 52 drives the transmission wheel 53 to rotate via the transmission belt 54, and the transmission wheel 53 drives the main shaft 4 to rotate. The axis of the drive wheel 52 coincides with the axis of the drive motor 51, and the axis of the transmission wheel 53 coincides with the axis of the main shaft 4. In some other embodiments, the transmission belt 54 can also be replaced by a transmission rope or a transmission chain. In some other embodiments, in addition to using the drive motor 51 and the belt transmission mechanism to drive the main shaft 4, the transducer drive mechanism 5 can also use the drive motor 51 and a gear train to drive the main shaft 4, or can use the drive motor 51 to directly drive the main shaft 4 to rotate.

[0064] Further, in one embodiment, please refer to Figure 2 , at least part of the power module 8 is configured in the handle housing 1. Specifically, the power module 8 is fixed in the handle housing 1, which facilitates the installation of the power module 8. In some other embodiments, in addition to being installed in the handle housing 1, the power module 8 can also be used as a separate module to be plugged and fixed to the handle housing 1. In one embodiment, please refer to Figure 4 The power module 8 is detachably fixed to the proximal end of the handle housing 1. The power module 8 has a module housing 81, and the module housing 81 can be detachably connected to the handle housing 1 by means of fasteners, buckles, clamps, or other structures. The detachable connection of the power module 8 makes it easier to maintain or quickly replace.

[0065] In one embodiment, the power module 8 includes a charging module and a battery, and the battery can be charged by the charging module. In some other embodiments, the power module 8 can also use dry batteries.

[0066] Specifically, in one embodiment, please refer to Figure 1 and Figure 2The handle housing 1 has a charging port 11, which is located on the proximal end surface of the handle housing 1. This makes it convenient to connect the charging port 11 to the charger.

[0067] In one embodiment, please refer to Figure 2 The ultrasonic intracavitary probe includes a circuit board 10, which is fixed in the handle housing 1. At least one of the wireless communication module 7 and the control module 6 is integrated on the circuit board 10. In one embodiment, both the wireless communication module 7 and the control module 6 are integrated on the circuit board 10. In one embodiment, the wireless communication module 7 can be any other feasible communication module such as a Wi-Fi module, a Bluetooth module, etc. In one embodiment, the control module 6 can be in any feasible form, such as a CPU or a single-chip microcomputer.

[0068] In order to maintain the stability of the circuit board 10, in one embodiment, please refer to Figure 2 and Figure 3 The circuit board 10 is fixed on the motor housing 511 of the driving motor 51. This can not only keep the circuit board 10 stable, but also reduce the brackets in the handle housing 1.

[0069] Specifically, in one embodiment, please refer to Figure 2 and Figure 3 The ultrasonic intracavitary probe includes a mounting frame 101, through which the circuit board 10 is fixed to the motor housing 511. In one embodiment, the mounting frame 101 includes a mounting plate 1011, a side plate 1012, and a cantilever 1013. The mounting plate 1011 is fixed to the distal end of the motor housing 511. There are two side plates 1012, which are clamped on opposite sides of the motor housing 511. The cantilever 1013 extends toward the proximal end of the mounting plate 1011, and the circuit board 10 is fixed to the cantilever 1013.

[0070] In one embodiment, please refer to Figure 2 and Figure 3 , the mounting plate 1011 and the side plate 1012 are fixed to the motor housing 511 by fasteners. In one embodiment, please refer to Figure 2 and Figure 3 There are two cantilevers 1013 , and the circuit board 10 is fixed on the two cantilevers 1013 . The arrangement direction of the two cantilevers 1013 is consistent with the arrangement direction of the two side plates 1012 .

[0071] In one embodiment, please refer to Figure 2The ultrasonic intracavitary probe includes a rotating transducer line 102, which is connected to the rotating transducer 3. Since the rotating transducer 3 needs to rotate during operation, the rotating transducer line 102 connected to the rotating transducer 3 is prone to twisting. In order to avoid the rotating transducer line 102 from being twisted, in one embodiment, the ultrasonic intracavitary probe includes a slip ring 103, which includes a stator 1031 and a rotor 1032. The rotor 1032 rotates with the stator 1031 and is conductive with the stator 1031 so that the stator 1031 and the rotor 1032 can transmit signals and / or electrical energy. The stator 1031 is fixed in the handle housing 1, and the stator 1031 is communicatively connected to the wireless communication module 7.

[0072] The rotating transducer wire 102 is connected to the rotor 1032 so that the end of the rotating transducer wire 102 connected to the rotor 1032 can rotate when subjected to a torsional force. The rotor 1032 of the slip ring 103 is connected to the rotating transducer wire 102. In this way, when the rotating transducer wire 102 is subjected to a torsional force, the rotor 1032 can rotate under the action of the rotating transducer wire 102, thereby releasing the torsional force on the rotating transducer wire 102 and preventing the rotating transducer wire 102 from being damaged by twisting.

[0073] Specifically, the stator 1031 and the wireless communication module 7 can be directly connected via the stator lead 104, with information between the rotating transducer 3 and the wireless communication module 7 being transmitted via the rotating transducer wire 102, the rotor 1032, the stator 1031, and the stator lead 104. The stator 1031 can also be connected to the information processing module 9 and connected to the wireless communication module 7 via the information processing module 9. Information between the rotating transducer 3 and the wireless communication module 7 is transmitted via the rotating transducer wire 102, the rotor 1032, the stator 1031, and the information processing module 9.

[0074] Specifically, in one embodiment, please refer to Figure 2 and Figure 3 The stator 1031 is fixed to the motor housing 511 of the drive motor 51. Specifically, the stator 1031 and the circuit board 10 are both fixed to the mounting bracket 101. The stator 1031 is fixed to the two side panels 1012. The two side panels 1012 are fixed to the stator 1031, which provides high stability to the stator 1031. In some other embodiments, the stator 1031 can also be fixed to the inner wall of the handle housing 1.

[0075] In one embodiment, please refer to Figure 2 and Figure 3The stator 1031 and the circuit board 10 share a mounting bracket 101, which simplifies the internal structure of the handle housing 1 and achieves a higher degree of integration. The circuit board 10 and the stator 1031 are arranged in the longitudinal direction of the handle housing 1, so that their positions are staggered and they are unlikely to interfere with each other. In addition, the stator 1031 and the circuit board 10 share a mounting bracket 101, and the stator 1031 is close to the distal end of the circuit board 10 and away from the proximal end of the circuit board 10. This allows the wires leading from the stator 1031 to be easily connected to the circuit board 10.

[0076] Regarding the structure of the main shaft 4, in one embodiment, please refer to Figure 2 The main shaft 4 is a hollow shaft having a central hole 41. At least a portion of the rotary transducer wire 102 is located in the central hole 41 and extends along the central hole 41. In this way, when the main shaft 4 rotates about its axis, the rotary transducer wire 102 located in the central hole 41 will not be entangled with the main shaft 4.

[0077] In one embodiment, please refer to Figure 2 The main shaft 4 is fixedly connected to the rotor 1032. The main shaft 4 and the rotor 1032 can be connected by any feasible method, such as welding, keying, bonding, magnetic attraction, or fasteners. In some other embodiments, in addition to being directly fixed to the main shaft 4, the rotor 1032 can be assembled together by a rotationally fixed assembly method, such as by splines between the rotor 1032 and the main shaft 4.

[0078] In one embodiment, please refer to Figure 2 The rotor 1032 is directly mounted on the main shaft 4 and rotates with the main shaft 4. At this time, the rotor 1032, the rotating transducer line 102 and the main shaft 4 can rotate synchronously around the axis of the main shaft 4, further reducing the torque applied to the rotating transducer 3.

[0079] Of course, in one embodiment, since the main shaft 4, the rotating transducer wire 102, the rotor 1032 and the rotating transducer 3 rotate synchronously, according to actual needs, the rotating transducer wire 102 can also be arranged on the outer peripheral surface of the main shaft 4. In this case, the main shaft 4 can also be a solid shaft, and the rotating transducer wire 102 extends to the position of the rotor 1032 and needs to be connected to the rotor 1032.

[0080] Regarding the installation method of the main shaft 4, in one embodiment, please refer to Figure 2, the main shaft 4 extends along the length direction of the handle housing 1, and the ultrasonic intracavitary probe includes a sealing seat 105, which separates the inner cavity of the handle housing 1 from the inner cavity of the intracavitary housing 2. The main shaft 4 seals through the sealing seat 105 to enter the intracavitary housing 2, and the rotor 1032 is in the handle housing 1. The inner cavity of the handle housing 1 is separated from the inner cavity of the intracavitary housing 2 by the sealing seat 105, which facilitates the filling of coupling liquid into the intracavitary housing 2. The rotor 1032 is arranged in the handle housing 1, which can prevent the coupling liquid filled in the intracavitary housing 2 from having a bad influence on the rotor 1032. Of course, in some other embodiments, the handle housing 1 can also be connected to the intracavitary housing 2. In this case, the rotor 1032 can be arranged in the intracavitary housing 2 or the handle housing 1 as needed.

[0081] Regarding the type of slip ring 103, in one embodiment, please refer to Figure 2 The slip ring 103 is a conductive slip ring 103 or a fiber optic slip ring 103. The rotor 1032 of the conductive slip ring 103 is electrically connected to the stator 1031. Specifically, the conductive slip ring 103 can be any feasible type, such as a hollow shaft conductive slip ring 103 or a through-hole conductive slip ring 103. Fiber optic slip rings 103 can transmit optical signals via optical fibers and are typically used for high-speed data transmission.

[0082] In one embodiment, please refer to Figure 2 The rotor 1032 is cylindrical, the distal end of the rotor 1032 is fixed to the proximal end of the main shaft 4 by a fastener, the proximal end of the rotor 1032 is assembled with the stator 1031, and the rotor 1032 and the stator 1031 can rotate relative to each other.

[0083] Further, in one embodiment, please refer to Figure 2 and Figure 3 The intracavitary housing 2 includes an acoustic window 21 and a connecting housing 22. The connecting housing 22 is connected to the handle housing 1. The acoustic window 21 is connected to the distal end of the connecting housing 22. The rotary transducer 3 is located in the acoustic window 21. The end of the connecting housing 22 facing away from the acoustic window 21 is connected to the handle housing 1. One end of the main shaft 4 is connected to the acoustic window 21 via a bearing. The other end of the main shaft 4 is in driving connection with the transducer drive mechanism 5.

[0084] During the inspection process, the ultrasonic intracavitary probe is inserted into the human body cavity for a complete circumferential scan in order to obtain data of the inspection part, such as inspecting the pelvic cavity through the ultrasonic intracavitary probe. When the ultrasonic intracavitary probe is scanning in the body cavity, the transducer drive mechanism 5 drives the main shaft 4 to rotate in the intracavitary shell 2. When the rotating transducer 3 rotates, the rotating transducer line 102 connected to the rotating transducer 3 also rotates around the axis of the main shaft 4. The inspection data obtained is transmitted to the wireless communication module 7 through the rotating transducer line 102, the slip ring 103 and the information processing module 9, and then sent to the ultrasound host through the wireless communication module 7. During the inspection process, since the ultrasonic intracavitary probe and the ultrasound host rely on the wireless communication module 7 for information transmission, there is no connecting line between the ultrasonic intracavitary probe and the ultrasound host, making it easier and more convenient to operate the ultrasonic intracavitary probe.

[0085] In an embodiment of an ultrasound device, the ultrasound device includes an ultrasound host and an ultrasound intracavity probe as described in any of the above embodiments, and the details are not repeated here. There is no cable connecting the ultrasound host and the ultrasound intracavity probe, so the ultrasound intracavity probe can move flexibly and freely, making it more convenient to operate.

[0086] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
