Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical equipment, and in particular to a wireless ultrasound probe. Background Art
[0002] The 360 ultrasound probe includes a rotating shaft and a transducer that can rotate back and forth. During rotational inspection, the transducer's unidirectional rotation angle is greater than 180°. A transducer that rotates back and forth at a large angle can obtain images over a wider range during ultrasound testing. The rotating shaft of the 360 ultrasound probe extends from the proximal end to the distal end, and the transducer is fixed on the rotating shaft.

[0057] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.
[0058] 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).
[0059] In response to the problem that the transducer wire in the current 360 probe is easily damaged by twisting, the present application provides an ultrasound probe. The ultrasound probe has a slip ring, which is connected to the transducer wire through the rotor of the slip ring. In this way, the transducer wire can rotate relative to the stator of the slip ring after being subjected to a twisting force, and the transducer is not easily damaged by excessive torque.
[0060] In one embodiment, please refer to Figure 1 and Figure 2 The ultrasound probe includes a handle housing 1, an intracavity housing 2, a transducer 3, a main shaft 4, a transducer drive mechanism 5, a transducer cable 6, and a slip ring 7. The handle housing 1 is used for the operator to hold the ultrasound probe. The proximal end of the intracavity housing 2 is connected to the distal end of the handle housing 1, and the intracavity housing 2 is used to extend into the patient's cavity.
[0061] 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 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 endocavity housing 2, the proximal end of the endocavity housing 2 is closer to the operator, and the distal end is farther from the operator.
[0062] Please refer to Figure 2 At least a portion of the main shaft 4 is located within the intracavitary housing 2, and the transducer 3 is disposed within the intracavitary housing 2 and mounted on the main shaft 4, so that the main shaft 4 can drive the transducer 3 to rotate about the axis of the main shaft 4. In one embodiment, the transducer 3 rotates in a single direction at a rate greater than or equal to 180° during a scanning inspection, such that the sum of the rotation angles of the transducer 3 during a reciprocating motion functional cycle is no less than 360°. In one embodiment, the transducer 3 can also rotate in a single direction at a rate greater than or equal to 360° during a scanning inspection.
[0063] Please refer to Figure 2 , the transducer drive mechanism 5 is connected to the main shaft 4 in a transmission manner to drive the main shaft 4 to rotate, thereby driving the transducer 3 on the main shaft 4 to rotate. The transducer wire 6 is connected to the transducer 3. When the transducer 3 rotates, since the transducer wire 6 is connected to the transducer 3, one end of the transducer wire 6 rotates with the transducer 3. In order to reduce the torsion of the transducer wire 6, the transducer wire 6 is connected to the rotor 71 of the slip ring 7, and the stator 72 of the slip ring 7 is fixed in the handle housing 1. In some other embodiments, the stator 72 can also be fixed in the intracavitary housing 2. The rotor 71 rotates in coordination with the stator 72 and is conductive with the stator 72, so that the stator 72 and the rotor 71 can transmit signals and / or electrical energy. The transducer wire 6 is connected to the rotor 71 so that the end of the transducer wire 6 connected to the rotor 71 can rotate when subjected to a torsional force.
[0064] In the ultrasonic probe of the present application, the rotor 71 of the slip ring 7 is connected to the transducer wire 6. After the transducer wire 6 is subjected to a torsional force, the rotor 71 can rotate under the action of the transducer wire 6, thereby releasing the torsional force on the transducer wire 6, and making the transducer wire 6 less likely to be damaged by twisting.
[0065] Further, regarding the transducer drive mechanism 5, in one embodiment, please refer to Figure 2 The transducer drive mechanism 5 includes a drive motor 51, and a stator 72 is fixed to a motor housing 511 of the drive motor 51. In one embodiment, the drive motor 51 is fixed in the handle housing 1. Fixing the stator 72 to the motor housing 511 is more convenient for installation than fixing the stator 72 to the handle housing 1. In some other embodiments, the stator 72 can also be fixed to the inner wall of the handle housing 1, or a bracket can be fixed in the handle housing 1, and the stator 72 can be mounted on the bracket.
[0066] Further, in one embodiment, please refer to Figure 2 and Figure 3The ultrasound probe includes a stator mounting bracket 8, through which the stator 72 is fixed to the motor housing 511. The stator 72 is mounted on the stator mounting bracket 8. Securing the stator 72 via the stator mounting bracket 8 further facilitates assembly of the stator 72. In some other embodiments, the stator 72 can also be directly fixed to the motor housing 511. In this case, the shape and size of the stator 72 must meet installation requirements.
[0067] In order to simplify the structure, further, in one embodiment, please refer to Figure 2 and Figure 3 The ultrasonic probe includes a circuit board (not shown in the figure), which is fixed on the stator mounting frame 8. The circuit board and the slip ring 7 are arranged along the length direction of the handle housing 1. The stator 72 and the circuit board share a mounting frame, which can simplify the structure inside the handle housing 1 and achieve a higher degree of integration. The circuit board and the slip ring 7 are arranged in the length direction of the handle housing 1, which can stagger their positions and prevent them from interfering with each other. In some other embodiments, the circuit board can also be directly fixed in the handle housing 1. Of course, a circuit board bracket can also be added to the handle housing 1, and the circuit board bracket can fix the circuit board separately.
[0068] It should be noted that the length direction of the handle housing 1 is the direction in which the proximal end and the distal end of the handle housing 1 are arranged, that is, the two ends of the handle housing 1 in its length direction are the proximal end and the distal end respectively.
[0069] Specifically, in one embodiment, please refer to Figure 2 and Figure 3 The stator mounting frame 8 includes a mounting plate 81, a side plate 82 and a cantilever 83, wherein the mounting plate 81 is fixed to the distal end of the motor housing 511, and there are two side plates 82. The two side plates 82 are clamped on opposite sides of the motor housing 511, and the cantilever 83 extends toward the proximal side of the mounting plate 81. The circuit board is fixed on the cantilever 83. The stator 72 is fixed on the two side plates 82 and is fixed to the stator 72 by the two side plates 82, so that the stability of the stator 72 is higher. In one embodiment, the mounting plate 81 and the side plates 82 are fixed to the motor housing 511 by fasteners. In one embodiment, there are two cantilevers 83, and the circuit board is fixed on the two cantilevers 83. The arrangement direction of the two cantilevers 83 is consistent with the arrangement direction of the two side plates 82.
[0070] In one embodiment, please refer to Figure 2 The stator 72 and the circuit board extend in the length direction of the handle housing 1, and the stator 72 is close to the distal end of the circuit board and away from the proximal end of the circuit board, so that the wires led out from the stator 72 can be easily connected to the circuit board.
[0071] Further, in one embodiment, please refer to Figure 2The slip ring 7 is located on one radial side of the drive motor 51, and the rotation axis of the rotor 71 is parallel to the axis of the drive motor 51 and spaced apart. This makes installation of the slip ring 7 more convenient and fully utilizes the space inside the handle housing 1. In some other embodiments, the slip ring 7 can also be coaxial with the drive motor 51, that is, the rotation axis of the rotor 71 in the slip ring 7 coincides with the axis of the drive motor 51.
[0072] Specifically, in one embodiment, please refer to Figure 2 and Figure 3 The transducer drive mechanism includes a drive wheel 52 connected to a drive motor 51 and a transmission wheel 53 fixed to the main shaft 4. It also includes a transmission belt 54 connecting the drive wheel 52 and the transmission wheel 53. When 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 through the timing 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 rotating gear coincides with the axis of the main shaft 4.
[0073] In some other embodiments, the transmission belt 54 may be replaced by a transmission rope or a transmission chain. In some other embodiments, in addition to using the drive motor 51 and a belt transmission mechanism to drive the main shaft 4, the transducer drive mechanism 5 may also use the drive motor 51 and a gear train to drive the main shaft 4, or may use the drive motor 51 to directly drive the main shaft 4 to rotate.
[0074] In one embodiment, the rotor is shown in FIG. Figure 2 The rotation axis of rotor 71 is parallel to or coincides with the rotation axis of transducer 3. This facilitates the connection between transducer cable 6 and rotor 71. In other embodiments, under special circumstances, the rotation axis of rotor 71 may also form a certain angle with the rotation axis of transducer 3. In this case, when transducer cable 6 is subjected to torsion, rotor 71 can also rotate to reduce the magnitude of the torsion applied to transducer 3.
[0075] Further, in one embodiment, please refer to Figure 2 The rotor 71 is coaxial with the main shaft 4 and is locked so that the rotor 71 rotates with the main shaft 4. When the rotor 71 is directly mounted on the main shaft 4 and rotates with the main shaft 4, the rotor 71, the transducer cable 6, and the main shaft 4 can rotate synchronously around the axis of the main shaft 4, further reducing the torsional load on the transducer 3. In some other embodiments, in addition to directly mounting the rotor 71 on the main shaft 4, the rotor 71 can also be rotatably mounted on the handle housing 1 or the motor housing.
[0076] Specifically, in one embodiment, please refer to Figure 2The main shaft 4 is fixedly connected to the rotor 71. The main shaft 4 and the rotor 71 can be connected by any feasible means, such as welding, key connection, bonding, magnetic attraction, or fastener fixation. In some other embodiments, in addition to being directly fixed to the main shaft 4, the rotor 71 can be assembled together by a rotation-proof assembly method, such as by spline assembly between the rotor 71 and the main shaft 4.
[0077] In one embodiment, please refer to Figure 2 The rotor 71 and the transmission wheel 53 are arranged in the axial direction of the main shaft 4. The rotor 71 is fixed at the proximal end of the main shaft 4, and the transmission wheel 53 is fixed between the rotor 71 and the distal end of the main shaft 4, which facilitates the installation of the slip ring 7.
[0078] Further, 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 transducer wire 6 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 transducer wire 6 located in the central hole 41 will not be entangled with the main shaft 4.
[0079] Of course, in one embodiment, since the main shaft 4, transducer wire 6, rotor 71 and transducer 3 rotate synchronously, according to actual needs, the transducer wire 6 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 transducer wire 6 extends to the position of the rotor 71 and needs to be connected to the rotor 71.
[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 shell 1, and the ultrasonic probe includes an intermediate sealing seat 9, which separates the inner cavity of the handle shell 1 from the inner cavity of the intracavity shell 2. The main shaft 4 seals through the intermediate sealing seat 9 to enter the intracavity shell 2, and the rotor 71 is in the handle shell 1. The inner cavity of the handle shell 1 is separated from the inner cavity of the intracavity shell 2 by the intermediate sealing seat 9, which facilitates the filling of the medium into the intracavity shell 2. The rotor 71 is arranged in the handle shell 1 to prevent the medium filled in the intracavity shell 2 from having a bad influence on the rotor 71. Of course, in some other embodiments, the handle shell 1 can also be connected with the intracavity shell 2. In this case, the rotor 71 can be arranged in the intracavity shell 2 or the handle shell 1 as needed.
[0081] Regarding the type of slip ring 7, in one embodiment, please refer to Figure 2 The slip ring 7 is a conductive slip ring or a fiber optic slip ring. The rotor 71 of the conductive slip ring is electrically connected to the stator 72. Specifically, the conductive slip ring can be of any feasible type, such as a hollow shaft conductive slip ring or a through-hole conductive slip ring. Fiber optic slip rings 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 slip ring 7 is a conductive slip ring with a hollow structure. The rotor 71 is cylindrical, and the distal end of the rotor 71 is fixed to the proximal end of the main shaft 4 by fasteners. The proximal end of the rotor 71 is assembled with the stator 72, and the rotor 71 and the stator 72 can rotate relative to each other.
[0083] Based on the type of the slip ring 7 , the transducer line 6 can be of various feasible types. For example, the transducer line 6 can include a conductive wire for electrical connection or an optical fiber for transmitting optical signals.
[0084] Further, in one embodiment, please refer to Figure 2 and Figure 3 The ultrasound probe also includes a lead wire 10 connected to the stator 72. The lead wire 10 extends through the handle housing 1 for connection to the ultrasound host. The lead wire 10 enables signal exchange and circuit continuity between the ultrasound probe and the ultrasound host. In some other embodiments, the stator 72 may be fixed to a circuit board, and the ultrasound host may be connected to the circuit board.
[0085] 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 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.
[0086] During an examination, an ultrasound probe is inserted into a body cavity and scans a complete circumference to obtain data from the portion being examined, such as a pelvic examination. As the ultrasound probe scans the body cavity, the transducer drive mechanism 5 rotates the main shaft 4 within the cavity housing 2. As the transducer 3 rotates, the transducer cable 6 connected to the transducer 3 also rotates around the axis of the main shaft 4.
[0087] In an embodiment of an ultrasound device, the ultrasound device includes an ultrasound host and an ultrasound probe as described in any of the above embodiments, and the details are not repeated here. The ultrasound probe is connected to the ultrasound host and can at least exchange signals.
[0088] 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.
