[0031] The related art provides an ultrasonic puncture device, which comprises a puncture needle, an ultrasonic probe, and a display in communication connection with the ultrasonic probe. One hand of an operator acts on a target to be punctured by the ultrasonic probe, and the other hand of the operator stabs the puncture needle into the target to be punctured. When the ultrasonic wave emitted by the ultrasonic probe is conducted to the puncture needle, part of the ultrasonic wave is reflected by the puncture needle, and the ultrasonic probe receives the reflected ultrasonic wave, so that the display displays the ultrasonic image of the puncture needle in the target to be punctured in real time.

[0032] However, the intensity of the reflected part of the ultrasonic wave is small, and the clarity of the puncture needle image formed is low.

[0033] In view of the above technical problems, please refer to Figure 1 The embodiments of the present application provide an ultrasonic puncture device, which comprises an ultrasonic generator 100 and a puncture needle 200. The ultrasonic generator 100 vibrates and drives the puncture needle 200 to vibrate, so that the ultrasonic generator 100 emits a first ultrasonic wave, and the puncture needle 200 emits a second ultrasonic wave. The device further comprises an ultrasonic receiver 300 and a display (not shown). The ultrasonic generator 100, the puncture needle 200, and the display are in communication connection with the ultrasonic receiver 300. The ultrasonic receiver 300 is used to receive the first ultrasonic wave and the second ultrasonic wave and feed back to the display, so that the display displays an ultrasonic image.

[0034] The ultrasonic puncture device provided by the embodiment of the present application is provided with an ultrasonic generator 100 and a puncture needle 200, the ultrasonic generator 100 vibrates and drives the puncture needle 200 to vibrate, the ultrasonic generator 100 can emit first ultrasonic waves, and the puncture needle 200 can emit second ultrasonic waves.

[0035] The ultrasonic receiver 300 is used to receive the first ultrasonic waves and the second ultrasonic waves and feed back to the display, and the display can display an ultrasonic image, in this process, the emission of the first ultrasonic waves and the second ultrasonic waves can provide ultrasonic images from multiple angles.

[0036] Specifically, when the first ultrasonic waves pass through the target to be punctured, the first ultrasonic waves can be used to form an ultrasonic image of the target to be punctured, and when the puncture needle 200 penetrates into the target to be punctured, the second ultrasonic waves can be used to form an ultrasonic image of the puncture needle 200 in the target to be punctured, compared with the prior art in which only the reflected part of the ultrasonic waves forms the ultrasonic image of the puncture needle 200, the second ultrasonic waves emitted by the puncture needle 200 itself as a signal source have higher intensity, and the ultrasonic image of the puncture needle 200 formed is clearer.

[0037] The ultrasonic generator 100 of the embodiment of the present application can be arranged on the puncture needle 200, and the puncture needle 200 is held by a human hand or a mechanical hand to perform a puncture operation. The ultrasonic generator 100 can also be sleeved on the fingers of the human hand or the mechanical hand, and the puncture needle 200 is held by the fingers during the puncture operation. It should be noted that the specific arrangement position of the ultrasonic generator 100 is not limited in the embodiment of the present application, as long as the puncture needle 200 can be driven to vibrate and the puncture needle 200 can emit second ultrasonic waves.

[0038] The preferred technical scheme of the ultrasonic puncture device of the embodiment of the present application is described below with reference to the drawings.

[0039] In some embodiments, referring to Figure 1 , the number of ultrasonic generators 100 is two, and the two ultrasonic generators 100 clamp the puncture needle 200.

[0040] In the embodiment, the number of ultrasonic generators 100 is two, and both of the two ultrasonic generators 100 can vibrate, which not only improves the intensity of the first ultrasonic waves emitted by the ultrasonic generator 100, but also improves the intensity of the second ultrasonic waves emitted by the puncture needle 200, thereby improving the clarity of the ultrasonic image of the puncture needle 200 in the target to be punctured.

[0041] And, the two ultrasonic generators 100 hold the puncture needle 200, not only can stably control the puncture direction and the puncture strength of the puncture needle 200, but also make the puncture needle 200 directly contact with the ultrasonic generator 100, so that the ultrasonic generator 100 directly drives the puncture needle 200 to vibrate, thereby making the intensity of the second ultrasonic wave generated by the puncture needle 200 larger, and further improving the clarity of the ultrasonic image of the puncture needle 200 formed by the second ultrasonic wave.

[0042] In some specific embodiments (not shown in the embodiment), the two ultrasonic generators 100 are provided with connecting portions, one of the two connecting portions is magnetic, the connecting portion with magnetism can attract the puncture needle 200 to position the puncture needle 200, and the connecting portion without magnetism is used to cooperate with the connecting portion with magnetism to provide additional support for the puncture needle 200, so as to ensure the stability of the puncture needle 200 during the puncture process.

[0043] In another specific embodiment, please refer to Figure 1 and Figure 2 , the two ultrasonic generators 100 are provided with elastic portions 110, and the two elastic portions 110 are used to elastically abut on the puncture needle 200, so that the two elastic portions 110 jointly hold the puncture needle 200.

[0044] In the embodiment, the elastic portion 110 can adapt to the slight change of the puncture needle 200. Specifically, this clamping mode can adapt to the diameter and shape change of the puncture needle 200 to provide stable fixing effect.

[0045] In some examples, the elastic portion 110 is a rubber portion or a silica gel portion, both of which have good elasticity and flexibility, which can not only adapt to the slight change of the puncture needle 200, but also will not damage the puncture needle 200.

[0046] Further, please refer to Figure 1 and Figure 2 , the two ultrasonic generators 100 are provided with anti-skid portions 120, and each anti-skid portion 120 is correspondingly arranged on each elastic portion 110, and the two anti-skid portions 120 are used to abut on the puncture needle 200.

[0047] In specific implementation, the anti-skid portion 120 includes a plurality of anti-skid textures or a plurality of small protrusions to enhance the friction force between the ultrasonic generator 100 and the puncture needle 200, and prevent the puncture needle 200 from sliding during the puncture operation.

[0048] In another embodiment, please refer to Figure 1 and Figure 2 , the ultrasonic generator 100 is annular.

[0049] In the embodiment, the annular ultrasonic generator 100 is convenient to be sleeved on the finger of the first operating body 400. Thus, when the puncture operation is performed, the operator does not need to use an additional fixing device, but only needs to sleeve the annular ultrasonic generator 100 on the finger, which simplifies the operation steps and improves the work efficiency.

[0050] It can be understood that the first operating body 400 can be a human hand or a mechanical hand, and the ultrasonic generator 100 is used to be sleeved on the finger of the first operating body 400.

[0051] When the operator is selected to puncture the puncture target, the experience and knowledge of the operator can be used to judge the specific situation to ensure the feasibility and effectiveness of the puncture. When the mechanical hand is selected to puncture the puncture target, the mechanical hand can provide higher stability.

[0052] Further, referring to Figure 1 and Figure 2 , the ultrasonic generator 100 comprises an adjusting ring 130 and a generator body 140 arranged on the adjusting ring 130, and the inner diameter of the adjusting ring 130 is adjustable.

[0053] The adjustable inner diameter of the adjusting ring 130 enables the ultrasonic generator 100 to adapt to the fingers of different sizes of the first operating body 400. Specifically, the inner diameter of the adjusting ring 130 can be adjusted according to the thickness of different fingers of the same operator or the thickness of the fingers of different operators, so as to ensure that the ultrasonic generator 100 is stably and comfortably fixed on the finger. The flexibility improves the application range of the ultrasonic generator 100.

[0054] The adjustable inner diameter of the adjusting ring 130 not only enables the ultrasonic generator 100 to closely fit the finger, but also adjusts the tightness of the adjusting ring 130 according to the needs of the operator, so as to improve the comfort of wearing the ultrasonic generator 100, avoid the compression or discomfort caused by excessive tightness, and also avoid the ultrasonic generator 100 from falling off or sliding due to excessive looseness, thereby improving the stability of the puncture process.

[0055] In a specific implementation, the adjusting ring 130 is an elastic ring which is not closed. The two ends of the elastic ring which are not closed are close to each other under the action of an external force, so that the inner diameter of the adjusting ring 130 becomes smaller. The two ends of the elastic ring which are not closed are away from each other under the action of an external force, so that the inner diameter of the adjusting ring 130 becomes larger.

[0056] In still some embodiments, the ultrasonic generator 100 is used to abut against the puncture target, and the pressure between the ultrasonic generator 100 and the puncture target is adjustable.

[0057] In the embodiment, the ultrasonic generator 100 is directly abutted with the target to be punctured, which can ensure that the first ultrasonic wave is directly transmitted to the target to be punctured, thereby reducing the energy loss of the first ultrasonic wave, improving the transmission efficiency of the first ultrasonic wave, and further improving the clarity of the ultrasonic image.

[0058] In addition, the pressure-adjustable design allows the operator to adjust the contact pressure between the ultrasonic generator 100 and the target to be punctured according to specific needs, which is beneficial to adapt to different puncture scenarios and ensure that the first ultrasonic wave has better transmission effect in different scenarios. For example, when the skeleton needs to be punctured, the hardness of the skeleton is strong, and the pressure between the ultrasonic generator 100 and the target to be punctured needs to be increased. For example, when the thigh needs to be punctured, the tissue of the thigh is thick, and the pressure between the ultrasonic generator 100 and the target to be punctured also needs to be increased. For example, when the abdominal cavity needs to be punctured, the tissue of the abdominal cavity is soft and shallow, and the pressure between the ultrasonic generator 100 and the target to be punctured needs to be reduced.

[0059] In some specific embodiments, the first operation body 400 is the hand of the operator, and the operator can control the force applied by the hand on the target to be punctured to adjust the pressure between the ultrasonic generator 100 and the target to be punctured.

[0060] In other specific embodiments (not shown in the embodiment), the first operation body 400 is a mechanical device, and a pressure adjusting mechanism can be provided on the mechanical device. The pressure adjusting mechanism controls the movement of the mechanical device in the direction towards the target to be punctured to adjust the pressure between the ultrasonic generator 100 and the target to be punctured. For example, the mechanical device can be a mechanical hand, and the pressure adjusting mechanism can be a hydraulic cylinder, an air cylinder or a telescopic rod.

[0061] In other embodiments (not shown in the embodiment), the number of ultrasonic generators 100 is more than two, at least one ultrasonic generator 100 is arranged on the first operation body 400, and the other ultrasonic generators 100 are arranged on the second operation body.

[0062] In the embodiment, the number of ultrasonic generators 100 is more than two, which can further improve the intensity of the first ultrasonic wave emitted by the ultrasonic generator 100, and further improve the intensity of the second ultrasonic wave emitted by the puncture needle 200, to further improve the clarity of the ultrasonic image of the puncture needle 200 in the target to be punctured.

[0063] Furthermore, by mounting at least one ultrasound generator 100 on the first operating body 400, the ultrasound generator 100 on the first operating body 400 is primarily used to resonate with the puncture needle 200, causing the puncture needle 200 to emit a second ultrasound wave; by mounting other ultrasound generators 100 on the second operating body, the ultrasound generators 100 on the second operating body are primarily used to generate a first ultrasound wave, allowing the first ultrasound wave to pass through the target to be punctured, thereby forming an ultrasound image of the target to be punctured. Thus, the first operating body 400 and the second operating body work together, with different functions, which not only allows for precise control of the clarity of the ultrasound image of the puncture needle 200 to achieve a more refined puncture operation, but also provides more comprehensive multi-angle ultrasound image information, facilitating more accurate observation of the position and puncture path of the puncture needle 200.

[0064] In practice, when the first operating body 400 is one of the operator's hands and the second operating body is the other hand of the operator, the two hands work together. One hand is used to hold the puncture needle 200 and the other hand is used to operate the ultrasound generator 100 to form an ultrasound image of the puncture needle 200 in the target to be punctured, making the operation more convenient.

[0065] It should be noted that the ultrasonic generator 100 and the ultrasonic receiver 300 have similar shapes and structures, which will not be described in detail here. It is important to note that the ultrasonic generator 100 is used to emit ultrasonic waves, and the ultrasonic receiver 300 is used to receive ultrasonic waves.

[0066] In some embodiments (not shown in this embodiment), the ultrasound receiver 300 is integrated with the display.

[0067] In this embodiment, only the ultrasonic generator 100 needs to be held, and the ultrasonic receiver 300 does not need to be held, making the operation simple, convenient, and highly efficient.

[0068] In other embodiments, the ultrasound receiver 300 is positioned opposite the ultrasound generator 100.

[0069] In this embodiment, the ultrasound receiver 300 and the ultrasound generator 100 are arranged opposite each other, so that the ultrasound receiver 300 and the ultrasound generator 100 are close to each other. The first ultrasound emitted by the ultrasound generator 100 has a shorter propagation path in the medium, less energy loss and attenuation, and the ultrasound receiver 300 can receive the first ultrasound with higher intensity, thereby improving the clarity of the ultrasound image of the target to be punctured.

[0070] In practice, the ultrasound receiver 300 and the ultrasound generator 100 can be located on opposite sides of the target to be punctured.

[0071] In some specific embodiments, the ultrasonic generator 100 and the ultrasonic receiver 300 are respectively fitted onto different fingers of the first operating body 400.

[0072] In this embodiment, the ultrasound generator 100 and the ultrasound receiver 300 are mounted on the same operating body (i.e., the first operating body 400), so only one operating body is needed to perform the puncture operation.

[0073] In some other specific embodiments (not illustrated in this embodiment), the ultrasonic generator 100 is disposed on the first operating body 400, and the ultrasonic receiver 300 is disposed on the second operating body.

[0074] In this embodiment, the ultrasonic generator 100 is mounted on the first operating body 400, and the ultrasonic receiver 300 is mounted on the second operating body. The second operating body can share the workload of the first operating body 400. In practical implementation, it can be operated by one operator's two hands or by two operators, which is quite convenient.

[0075] In other embodiments, the ultrasound receiver 300 and the puncture needle 200 are arranged opposite each other, and the ultrasound generator 100 and the puncture needle 200 are located on the same side of the ultrasound receiver 300.

[0076] In this embodiment, the ultrasound receiver 300 and the puncture needle 200 are arranged opposite each other, so that the distance between the ultrasound receiver 300 and the puncture needle 200 is relatively close. The propagation path of the second ultrasound emitted by the puncture needle 200 in the medium is shorter, and the energy loss and attenuation are smaller. The ultrasound receiver 300 can receive the second ultrasound with higher intensity, thereby improving the clarity of the ultrasound image of the puncture needle 200 in the target to be punctured.

[0077] In practice, the ultrasound receiver 300 and the puncture needle 200 can be located on opposite sides of the target to be punctured, while the ultrasound generator 100 and the puncture needle 200 are located on the same side of the target to be punctured.

[0078] In some other embodiments, the ultrasonic puncture device also includes a frequency converter (not shown) electrically connected to the ultrasonic generator 100, which can adjust the vibration frequency of the ultrasonic generator 100.

[0079] By adjusting the vibration frequency of the ultrasound generator 100, the operator can select an ultrasound frequency suitable for different depths and tissue types.

[0080] It should be understood that the embodiments of this application are not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
