[0023] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.
[0025] Nerve block is a commonly used anesthesia method in clinical work. Long-acting local anesthetics are injected around the target nerves to block the conduction of pain. It plays a pivotal role in the conduction of surgical operations and postoperative analgesia. Nerve block has the characteristics of minimal impact on systemic circulation, no respiratory depression, but definite analgesic effect. For patients with multiple organ damage or elderly and frail patients who cannot tolerate severe circulation fluctuations or cannot safely remove the endotracheal tube after intubation, nerve block is undoubtedly the best anesthesia option.
[0026] Nerve block was originally a blind operation. After roughly locating the body's anatomical structure, the puncture needle was inserted. The patient judged that the puncture needle had reached the target position by the needle tip touching the nerve, causing the patient to have a strange sensation. This caused much damage and the effect was not perfect.
[0027] The combination of ultrasound and nerve block makes the operation of nerve block a visual process. Although it greatly overcomes the disadvantage of blind exploration, it cannot solve the problem of the puncture needle effectively reaching the target area.
[0028] The ultrasonic probe acts as a transducer, converting the electrical signal emitted by the host into ultrasonic waves. The ultrasonic waves are transmitted into human tissues and then return to the ultrasonic probe after encountering a reflection interface. The ultrasonic probe acts as a receiver, converting the sound waves into electrical signals and transmitting them back to the host. The ultrasonic probe has a certain thickness, but the ultrasonic emission plane (or ultrasonic imaging plane) is very narrow, usually located on the transverse mid-axis plane of the ultrasonic probe. Objects can only be displayed on the ultrasonic image if they appear in the ultrasonic emission plane. However, in actual operation, the two objects are often not in the same plane and cannot be imaged at the same time. For example, the ultrasonic probe finds the best puncture plane but cannot find the puncture needle. For example, the ultrasonic probe finds the puncture needle but misses the best puncture plane. This brings great confusion to novices learning this technology and greatly prolongs the learning cycle.
[0029] The commonly used ultrasound-guided nerve block puncture techniques in clinical practice are divided into in-plane puncture and out-of-plane puncture according to whether the puncture needle is in the ultrasonic emission plane throughout the process. In-plane puncture requires that the puncture needle is in the ultrasonic emission plane, and the needle body and trajectory of the puncture needle can be clearly seen on the ultrasound image. It is often used in the case where the target area is shallow and there are no structures that need to be avoided (such as blood vessels, internal organs, bones, etc.) on the path from the puncture point to the target area. The out-of-plane puncture ultrasound image will not show the trajectory of the puncture needle, but only the needle tip or a cross-section of a certain section of the needle body when the puncture needle reaches the ultrasonic emission plane. That is, the path of the puncture needle piercing the human body to reach the ultrasonic emission plane cannot be displayed. It is often used in the case where the puncture target area is deep or there are structures that need to be avoided on the path of in-plane puncture. Whether it is in-plane puncture or out-of-plane puncture, the operator's hand holding the probe and the hand holding the puncture needle are required to cooperate perfectly, otherwise the needle tip cannot accurately reach the target area and complete this nerve block operation. Especially for the out-of-plane puncture technique, even experienced operators need to make multiple adjustments to complete it, and it is even more difficult for inexperienced operators (e.g. beginners) to complete it. In addition, repeatedly adjusting the puncture angle and path of the puncture needle will cause great pain to the patient and will also cause unnecessary iatrogenic damage.
[0030] In response to the above problems, the embodiments of the present application provide a notched ultrasound probe and anesthesia puncture device for nerve block. By optimizing and modifying the ultrasound probe, when performing the puncture operation, the operator can insert the puncture needle into the human body close to the first functional surface of the ultrasound probe to achieve in-plane puncture, thereby ensuring that the puncture needle body can always be displayed in the ultrasound image after entering the human body, which is beneficial for the operator to understand all conditions on the forward path of the puncture needle, and in-plane puncture can be performed for both shallow and deep targets, thereby improving the puncture accuracy and puncture efficiency, reducing adverse complications, reducing the great pain caused to patients by multiple punctures to reach the target area, and reducing the interference of the operator's operating experience on the implementation effect of nerve block, which is beneficial to shortening the operator's learning cycle, and thus can overcome the many shortcomings of the blind probing method and the existing ultrasound-guided nerve block puncture method.
[0031] The following is a detailed description with reference to specific embodiments. It should be noted that the serial numbers of the following embodiments are not intended to limit the preferred order of the embodiments.
[0032] See also Figure 1 , Figure 1 Schematic diagram of the structure of the notched ultrasound probe for nerve block provided in the embodiment of the present application. Figure 1 As shown, the notched ultrasound probe 10 may include a probe portion 11, which is configured to form an ultrasound imaging plane S1, and may include a first functional surface F1. The first functional surface F1 is configured to guide a puncture needle (e.g., a first puncture needle 21) that is in close contact with the first functional surface F1 into the ultrasound imaging plane S1 for in-plane puncture, thereby ensuring that the puncture needle is in close contact with the first functional surface F1 and its trajectory after puncturing the human body can be clearly seen, and the ultrasound image can easily display the best puncture plane while also displaying the full view of the puncture needle after entering the human body.
[0033] Specifically, the probe part 11 may include a transducer, and the transducer in the probe part 11 is used to convert the electrical signal emitted by the host into ultrasonic waves, which are transmitted into human tissues, and then return to the probe part 11 after encountering a reflection interface. Accordingly, the ultrasonic imaging plane S1 may be the ultrasonic emission plane of the probe part 11, and objects located in the ultrasonic imaging plane S1 may be displayed on the ultrasonic image, so that the operator can perform the puncture operation based on the ultrasonic image when the notch ultrasonic probe 10 finds the best puncture interface.
[0034] In some embodiments, Figure 1 As shown, the ultrasound imaging plane S1 may be located on one side of the probe portion 11 along the first lateral direction Y, wherein the first lateral direction Y may be the width direction of the probe portion 11. Figure 1As shown, the ultrasonic imaging plane S1 may be formed in front of the probe part 11 .
[0035] In some embodiments, Figure 1 As shown, the notch ultrasound probe 10 may further include a handheld portion 12, which is used for the operator to hold and may be in the shape of a long strip. Specifically, the handheld portion 12 and the probe portion 11 may be connected, for example, vertically connected. In some examples, such as Figure 1 As shown, the handheld portion 12 and the probe portion 11 can be connected to form an L-shaped structure.
[0036] In some specific embodiments, Figure 1 As shown, the handheld portion 12 and the ultrasound imaging plane S1 may be located on opposite sides of the probe portion 11, for example, they may be located on opposite sides of the probe portion 11 along the first horizontal direction Y. In some examples, such as Figure 1 As shown, the hand-held part 12 and the ultrasonic imaging plane S1 may be located behind and in front of the probe part 11 respectively.
[0037] In some embodiments, Figure 1 As shown, the ultrasound imaging plane S1 may be located on the transverse median axis of the probe portion 11 and may be symmetrical about the longitudinal median axis of the probe portion 11. Figure 1 As shown, the shape of the ultrasonic imaging plane S1 may be a sector symmetrical with respect to the longitudinal median axis of the probe portion 11 .
[0038] In some embodiments, Figure 1 As shown, the first functional surface F1 and the ultrasonic imaging plane S1 may be located in the same plane, or may be located substantially in the same plane, to ensure that the operator can insert the puncture needle (eg, the first puncture needle 21) into the human body close to the first functional surface F1 to achieve in-plane puncture.
[0039] Specifically, in the above-mentioned embodiment where the first functional surface F1 and the ultrasonic imaging plane S1 are located in the same plane, the first functional surface F1 and the ultrasonic imaging plane S1 may partially overlap, or may be connected to ensure that the puncture needle (for example, the first puncture needle 21) that is in close contact with the first functional surface F1 can directly enter the ultrasonic imaging plane S1 through the first functional surface F1.
[0040] Specifically, the first functional surface F1 and the ultrasonic imaging plane S1 are basically located in the same plane, which may mean that: the first functional surface F1 is parallel to the ultrasonic imaging plane S1, and the interval between the first functional surface F1 and the plane where the ultrasonic imaging plane S1 is located is not greater than a preset distance. The preset distance may satisfy: while ensuring that the first functional surface F1 can guide the puncture needle (for example, the first puncture needle 21) that is close to the first functional surface F1 into the ultrasonic imaging plane S1, the problem that the first functional surface F1 may cut off the ultrasonic imaging plane S1 is avoided, that is, the problem that the first functional surface F1 may cut off the ultrasonic imaging plane S1 in the solution where the first functional surface F1 and the ultrasonic imaging plane S1 are located in the same plane can be overcome.
[0041] In some embodiments, Figure 1 As shown, the probe portion 11 may further include a second functional surface F2, which intersects with the first functional surface F1, and the intersection line of the second functional surface F2 and the first functional surface F1 may be located within the central vertical plane of the ultrasonic imaging plane S1, so that the operator can insert the puncture needle (for example, the second puncture needle 22) into the human body close to the intersection line of the second functional surface F2 and the first functional surface F1, thereby achieving vertical puncture within the plane, and the puncture needle can reach the target area with the shortest distance.
[0042] Specifically, Figure 1 As shown, the second functional surface F2 can be located in the same plane as the central vertical plane of the ultrasonic imaging plane S1, or can be at an acute angle to the central vertical plane of the ultrasonic imaging plane S1, so that the operator can quickly position the puncture needle (for example, the second puncture needle 22) to the intersection of the second functional surface F2 and the first functional surface F1, thereby improving the puncture efficiency.
[0043] In some examples, the angle between the first functional surface F1 and the second functional surface F2 can be an obtuse angle, that is, it can be greater than 90 degrees, so that it is easier for the operator to quickly position the puncture needle (for example, the second puncture needle 22) to the intersection of the second functional surface F2 and the first functional surface F1, and it is more conducive to improving the puncture efficiency.
[0044] It should be noted that, for a target area that is close to the skin and where there is no structure that needs to be avoided on the puncture path, when puncturing, the puncture needle (for example, the first puncture needle 21) can be inserted close to the first functional surface F1 with the first functional surface F1 as a reference, so that the puncture needle can always be in the ultrasonic imaging plane S1 and appear on the ultrasonic image, and the puncture needle can be punctured at different angles close to the first functional surface F1.
[0045] Moreover, for a shallow target area that is far away from the skin or has a structure that needs to be avoided on the puncture path, when puncturing, the puncture needle (for example, the second puncture needle 22) can preferentially perform an in-plane puncture operation with reference to the intersection of the first functional surface F1 and the second functional surface F2, so that the puncture needle can always be displayed in the ultrasound image and the puncture needle can reach the target area with the shortest distance.
[0046] Compared with the related art, when puncturing a shallow target area that is far away from the skin or has a structure that needs to be avoided on the puncture path, the needle must be inserted from the outside of the ultrasound probe. In this embodiment, the ultrasound probe is optimized and modified, so that when puncturing a shallow target area that is far away from the skin or has a structure that needs to be avoided on the puncture path, the puncture needle can preferentially use the intersection of the first functional surface F1 and the second functional surface F2 as a reference to perform an in-plane puncture operation, thereby converting out-of-plane puncture into in-plane puncture, and achieving in-plane puncture under real-time ultrasound guidance for both shallow and deep targets, thereby greatly improving the accuracy and efficiency of puncture (especially puncture of deep targets).
[0047] In some specific embodiments, Figure 1 As shown, the ultrasonic imaging plane S1 can be located on one side of the probe part 11 along the first transverse direction Y, and a groove can be provided on one side edge of the probe part 11 along the second transverse direction X, and the second functional surface F2 and the first functional surface F1 can be provided by the inner wall surface of the groove, for example, they can be the side wall surface and the bottom wall surface of the groove respectively. Among them, the second transverse direction X is perpendicular to the first transverse direction Y, for example, they can be the length direction and the width direction of the probe part 11 respectively. In addition, the groove can penetrate the probe part 11 along the first transverse direction Y, that is, the length of the groove along the first transverse direction Y can be the same as the length of the side edge of the probe part 11 provided with the groove along the first transverse direction Y, so that the puncture needle (for example, the first puncture needle 21 and the second puncture needle 22) can directly enter the other side area of the probe part 11 along the first transverse direction Y from the one side area of the probe part 11 along the first transverse direction Y through the groove, so as to facilitate the puncture operation.
[0048] Specifically, the intersection line of the second functional surface F2 and the first functional surface F1 can be parallel to the center line of the ultrasonic imaging plane S1, and the spacing distance between it and the center line of the ultrasonic imaging plane S1 can not exceed the preset distance, so as to ensure that the intersection line of the second functional surface F2 and the first functional surface F1 can basically coincide with the center line of the ultrasonic imaging plane S1, and avoid the problem that the ultrasonic imaging plane S1 is cut off due to the intersection of the second functional surface F2 and the first functional surface F1.
[0049] Furthermore, in a specific implementation, the above-mentioned groove can be formed by cutting along the transverse mid-axis plane and the longitudinal mid-axis plane of the probe portion 11 on one side (e.g., the right side) of the second transverse direction X (e.g., the length direction) of the probe portion 11, thereby obtaining an asymmetric structure that lacks 1 / 4 of the entire structure on one side of the second transverse direction X, and allowing the intersection of the longitudinal mid-axis line and the transverse center line of the surface of the probe portion 11 that contacts the human skin to be exposed, which is more convenient for positioning the insertion point of the puncture needle.
[0050] Specifically, in the above-mentioned embodiment where the notch ultrasound probe 10 further includes a handheld portion 12, as shown in FIG. Figure 1 As shown, the hand-held portion 12 and the above-mentioned groove can be respectively located at the opposite ends of the above-mentioned probe portion 11 in the second horizontal direction X. For example, the hand-held portion 12 can be connected to one end of the probe portion 11 along the second horizontal direction X, and the above-mentioned groove can be provided at the edge of the other end of the probe portion 11 along the second horizontal direction X, so that when puncturing, the hand-held portion 12 can be prevented from blocking the placement of the puncture needles (for example, the first puncture needle 21 and the second puncture needle 22).
[0051] In some examples, such as Figure 1 As shown, the hand-held portion 12 may be connected to the right end of the probe portion 11 , and the groove may be provided at the left edge of the probe portion 11 .
[0052] In other examples, such as Figure 2 As shown, the hand-held portion 12 may be connected to the left end of the probe portion 11 , and the groove may be provided at the right edge of the probe portion 11 .
[0053] Furthermore, in a specific implementation, the notched ultrasound probe 10 in the embodiment in which the handheld portion 12 is connected to the right end of the probe portion 11 (see Figure 1 ), and the notch ultrasound probe 10 in the embodiment in which the handheld portion 12 is connected to the left end of the probe portion 11 (see Figure 2 ) can form a 180° mirror relationship.
[0054] In some examples, the handheld portion 12 may be provided with common ultrasound function buttons (eg, a depth adjustment function button, a freeze function button, and / or a defrost function button, etc.).
[0055] In some alternative embodiments, such as Figure 3 As shown, the probe part 11 may not include the second functional surface F2, and the first functional surface F1 may intersect with the central vertical plane of the ultrasonic imaging plane S1, for example, may intersect with the central vertical plane of the ultrasonic imaging plane S1 perpendicularly.
[0056] Specifically, in the above embodiment in which the probe portion 11 includes the above first functional surface F1 and does not include the above second functional surface F2, Figure 4 or Figure 5 As shown, a mark M may be provided on the first functional surface F1, and the mark M may be configured to mark the intersection line of the first functional surface F1 and the central vertical plane of the ultrasonic imaging plane S1, and the edge line of the first functional surface F1 located on the side where the ultrasonic imaging plane S1 is located, so that the operator can quickly position the puncture needle (for example, the second puncture needle 22) to the intersection line of the first functional surface F1 and the central vertical plane of the ultrasonic imaging plane S1 with the assistance of the mark M, thereby improving the puncture efficiency.
[0057] In some examples, such as Figure 4 As shown, the mark M can be designed to present a very fine red line structure after the power is turned on, and the line structure can coincide with the intersection of the first functional surface F1 and the central vertical plane of the ultrasonic imaging plane S1, and can coincide with the edge line of the first functional surface F1 located on the side of the ultrasonic imaging plane S1, so as to facilitate the operator to accurately determine the needle insertion point.
[0058] In other examples, such as Figure 5 As shown, the mark M can be designed to present a red, scaled, and extremely fine line structure after the power is turned on. The scaled extremely fine line structure can coincide with the edge line of the first functional surface F1 located on the side where the ultrasonic imaging plane S1 is located, and the scale thereon can at least mark the intersection of the edge line and the central vertical plane of the ultrasonic imaging plane S1, so as to facilitate the puncture needle (for example, the first puncture needle 21 and the second puncture needle 22) to find the insertion point.
[0059] Furthermore, it should be noted that, compared with the solution in which the probe portion 11 includes the second functional surface F2, the solution in which the probe portion 11 does not include the second functional surface F2 cancels the second functional surface F2, and by setting a mark M on the first functional surface F1, the operator is assisted in finding the insertion point of the puncture needle, which is more conducive to providing a wider operating space for the puncture needle, thereby making the puncture angle and orientation of the puncture needle wider.
[0060] Specifically, in the above embodiment in which the probe portion 11 includes the above first functional surface F1 and the above second functional surface F2, as shown in FIG. Figure 6 As shown, the probe portion 11 may further include a mark M, which may be configured to mark the intersection of the first functional surface F1 and the second functional surface F2, and an edge line of the first functional surface F1 on the side where the ultrasonic imaging plane S1 is located, so that the operator can quickly position the puncture needle (for example, the second puncture needle 22) to the intersection of the first functional surface F1 and the second functional surface F2 with the assistance of the mark M, thereby improving the puncture efficiency.
[0061] In the above embodiment, if Figure 1 , Figure 2 or Figure 3 As shown, the first functional surface F1 may be provided by at least a portion of the first surface of the probe portion 11, and the first surface is located on one side of the plane where the ultrasonic imaging plane S1 is located. In some examples, the first surface may be a side surface of the probe portion 11 along the longitudinal direction Z (for example, the upper surface or the lower surface), that is, the first functional surface F1 may be provided by a side surface of the probe portion 11 along the longitudinal direction Z, wherein the longitudinal direction Z may be the thickness direction of the probe portion 11.
[0062] Specifically, in the above embodiment in which the probe portion 11 includes the first functional surface F1 and the second functional surface F2, as shown in FIG. Figure 1 As shown, the first functional surface F1 may be the right half of the first surface (eg, the upper surface) of the probe portion 11, and accordingly, the hand-held portion 12 may be connected to the left end of the probe portion 11; or Figure 2 As shown, the first functional surface F1 may be the left half of the first surface (eg, the upper surface) of the probe portion 11 , and accordingly, the hand-held portion 12 may be connected to the right end of the probe portion 11 .
[0063] Specifically, in the above embodiment in which the probe portion 11 includes the first functional surface F1 and does not include the second functional surface F2, Figure 3 As shown, the first functional surface F1 may be the entire first surface (eg, upper surface) of the probe portion 11 , and accordingly, the hand-held portion 12 may be connected to the left end, the right end or the middle of the probe portion 11 .
[0064] In some embodiments, the notched ultrasound probe 10 may be a convex array ultrasound probe, a linear array ultrasound probe, or an ultrasound probe of other shapes.
[0065] In some embodiments, the notched ultrasonic probe 10 may be a high-frequency ultrasonic probe or a low-frequency ultrasonic probe.
[0066] As can be seen from the above, the notched ultrasound probe for nerve block provided in this embodiment includes a probe portion, which is configured to form an ultrasound imaging plane and includes a first functional surface, which intersects with the central vertical plane of the ultrasound imaging plane, and the first functional surface is configured to guide the puncture needle that is closely attached to the first functional surface into the ultrasound imaging plane for in-plane puncture, so that when performing the puncture operation, the operator inserts the puncture needle into the human body closely attached to the first functional surface, and in-plane puncture can be achieved, ensuring that the puncture needle body can always be displayed in the ultrasound image after entering the human body, which is beneficial for the operator to understand all situations on the puncture needle's advancing path, and in-plane puncture can be performed for both shallow and deep targets, thereby improving the puncture accuracy and puncture efficiency, reducing adverse complications, reducing the great pain caused to the patient by multiple punctures to reach the target area, and reducing the interference of the operator's operating experience on the implementation effect of nerve block, which is beneficial for shortening the operator's learning cycle.
