Description

[0001] This application claims priority to the following application: Chinese patent application No. 201922108008.0 filed on November 29, 2019, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present invention relates to the technical field of medical equipment, and in particular to an ultrasonic inspection device. Background Art

[0003] Ultrasound examination is a basic means for doctors to obtain information about lesions and is also the key to diagnosing diseases. Ultrasound interventional diagnosis and treatment devices generally include an ultrasound probe and a puncture stand installed on the ultrasound probe. After the ultrasound probe diagnoses the location of the lesion, the puncture needle is inserted into the lesion to obtain living tissue.

[0004] Take the breast cancer biopsy puncture operation as an example. The existing diagnostic device generally uses a two-dimensional ultrasonic probe equipped with a puncture frame, which makes it difficult to accurately find the puncture position and puncture the puncture needle to the designated position to obtain living tissue. Because the breast is easily deformed under the rotation and pressure of the ultrasonic probe, and the breast cancer lesion itself is difficult to accurately find and locate through two-dimensional ultrasound. In addition, the staff needs to operate the equipment by hand, and the operational stability is difficult to ensure, which ultimately leads to the puncture easily deviating from the lesion, causing secondary damage to the patient. If a diagnostic device with a three-dimensional ultrasonic probe and a puncture frame is used, the ultrasonic transducer is rotatably installed inside the outer shell of the probe end, and the puncture frame is fixed on the outer shell of the probe end. When the ultrasonic transducer rotates in the outer shell of the probe end to achieve three-dimensional imaging, the puncture frame fixed on the outer shell of the probe end cannot rotate synchronously with the ultrasonic transducer, and it is difficult to ensure that the puncture path of the puncture needle is on the scanning plane of the ultrasonic probe, and it is difficult to achieve accurate puncture. Therefore, currently very few three-dimensional ultrasound probes are used in ultrasound interventional treatment. Most ultrasound interventional treatments still use two-dimensional ultrasound probes. However, two-dimensional ultrasound probes can only provide two-dimensional ultrasound image information, which has great limitations for lesion diagnosis and puncture operation guidance.

[0087] Embodiment 1:

[0088] like Figure 1-Figure 6 As shown, this embodiment provides an ultrasonic inspection device, including a 3D ultrasonic probe A400 and a puncture frame A700 installed on the ultrasonic probe A400. The ultrasonic probe A400 includes a mounting shell A1 and an ultrasonic transducer A2 disposed in the mounting shell A1. The ultrasonic transducer A2 is spaced apart from the inner wall of the mounting shell A1. The ultrasonic transducer A2 can rotate in the mounting shell A1 to scan the relevant part to be inspected. The puncture frame A700 is disposed on the outside of the mounting shell A1. A puncture guide hole A721 for the puncture needle A900 to pass through is provided on the puncture frame A700. After the ultrasonic transducer A2 finds the lesion, the puncture needle A900 is inserted into the lesion to obtain living tissue.

[0089] The ultrasonic examination device also includes an operating table A100 and a driving mechanism disposed on the operating table A100. The patient lies on the operating table A100. The driving mechanism includes a driving member A200 and a transmission member A300. The driving member A200 is fixed on the operating table A100. The output end of the driving member A200 is connected to the transmission member A300, and the transmission member A300 is connected to the mounting shell A1 of the ultrasonic probe A400. The driving member A200 drives the transmission member A300 to move, and the transmission member A300 then drives the entire ultrasonic probe A400 to move to the patient's part to be examined. The driving member A200 is preferably a motor, and the transmission member A300 is preferably a connecting rod assembly, which is not limited here.

[0090] The ultrasonic inspection device also includes a host A600 and a display A500. The display A500 is used to display the ultrasonic image formed after the ultrasonic probe A400 scans the part to be inspected. The host A600 controls the ultrasonic probe A400, the puncture frame A700, the drive mechanism and the display A500 to work respectively. This is the prior art and will not be described in detail.

[0091] In this embodiment, the puncture frame A700 can rotate synchronously with the ultrasonic transducer A2, so that the axis of the puncture guide hole A721 on the puncture frame A700 is always on the real-time scanning plane A800 of the ultrasonic transducer A2, so as to achieve accurate puncture and obtain more efficient and accurate diagnosis and treatment.

[0092] Specifically, the ultrasonic inspection device also includes a first driving member A3 and a first spindle A4 disposed in the mounting shell A1. The output end of the first driving member A3 is connected to the first spindle A4 through a first transmission mechanism A5, and the first spindle A4 is connected to the ultrasonic transducer A2. An avoidance hole is provided on the mounting shell A1, and the first spindle A4 extends out of the mounting shell A1 through the avoidance hole and is connected to the puncture frame A700. The first driving member A3 drives the first spindle A4 to rotate through the first transmission mechanism A5, and the first spindle A4 drives the ultrasonic transducer A2 and the puncture frame A700 to rotate synchronously, so that the axis of the puncture guide hole A721 on the puncture frame A700 is always on the real-time scanning plane A800 of the ultrasonic transducer A2. The first driving member A3 is preferably a motor. Thereby, the synchronous rotation of the ultrasonic transducer A2 and the puncture frame A700 is realized.

[0093] The first transmission mechanism A5 is connected to the output end of the first driving member A3 through a gear. The first transmission mechanism A5 includes a worm, and a turbine is coaxially mounted on the first main shaft A4, and the worm drives the turbine to rotate. A turbine worm transmission with a self-locking function is adopted, and there is no need to introduce motor torque locking or additional electric or manual locking. Obviously, in other embodiments, belt drive or chain drive can also be used to achieve the transmission connection between the first transmission mechanism A5 and the first main shaft A4.

[0094] The puncture device comprises a frame A6 and a puncture guide A7. The frame A6 is fixedly connected to one end of the first main shaft A4 extending out of the mounting shell A1. The puncture guide A7 is rotatably mounted on the frame A6.

[0095] The frame body A6 includes a connecting portion A61 and a frame body A62 connected to each other. The connecting portion A61 may be tubular or semi-tubular, and is sleeved on one end of the first main shaft A4 extending out of the mounting shell A1. The connecting portion A61 is fixed to the first main shaft A4 by a fastener or a clamp. The connecting portion A61 preferably extends into the mounting shell A1 from the avoidance hole to prevent impurities such as dust or water vapor from entering the mounting shell A1 through the gap between the hole wall of the avoidance hole and the first main shaft A4, thereby achieving sealing and ensuring the service life of the ultrasonic transducer A2. A sealing ring may also be sleeved on the outer wall of the connecting portion A61 to further improve the sealing performance.

[0096] The puncture guide A7 includes an articulated frame A71 and a guide A72. The puncture guide hole A721 is provided on the guide A72. The guide A72 is fixed to the articulated frame A71. The bottom of the articulated frame A71 (the end close to the patient) is hinged to the frame body A62. A slide groove is provided on the frame body A62. The top of the articulated frame A71 (the end away from the patient) is provided with a matching portion, which is inserted into the slide groove, can slide in the slide groove, and can be fixed relative to the slide groove by a fastener.

[0097] Preferably, a plurality of positioning grooves A621 are provided on the groove wall of the slide groove. A protrusion A73 is provided on the mating portion. The articulated frame A71 is rotated, and the protrusion A73 can be inserted into any positioning groove A621, so as to realize the angle adjustment of the entire puncture guide A7 along the frame body A6 within the scanning plane A800 of the ultrasonic transducer A2, and ensure that the puncture needle A900 is accurately inserted into the lesion. Each positioning groove A621 corresponds to a number, and each positioning groove A621 corresponds to a different number. The protrusion A73 is inserted into different positioning grooves A621, and the corresponding puncture guide A7 rotates to different angles.

[0098] In addition, the guide member A72 may be provided with a plurality of puncture guide holes A721 of different sizes to accommodate puncture needles A900 of different sizes and to accommodate punctures of different parts.

[0099] Figure 4 The ultrasonic transducer A2 in the figure is a convex array ultrasonic transducer with good imaging quality, which is suitable for detecting deeper parts of the body. Figure 7 The ultrasonic transducer A2 in the figure is a linear array ultrasonic transducer, which has better image quality in superficial tissues and can provide better ultrasonic interventional diagnosis and treatment of superficial tissues.

[0100] See also Figure 8 The method for using the ultrasonic inspection device provided in this embodiment is roughly as follows:

[0101] Taking the puncture of breast A1000 lesion as an example, the mounting shell A1 of the ultrasonic probe A400 is pressed to the surface of the breast, and the mounting shell A1 remains stationary to avoid deformation of breast tissue caused by the movement of the mounting shell A1, thereby ensuring the accuracy of subsequent ultrasonic images. The first driving member A3 drives the first main shaft A4 to rotate through the first transmission mechanism A5, and the first main shaft A4 drives the ultrasonic transducer A2 to rotate, scans the three-dimensional ultrasonic image of the formed part of the breast, and displays it on the display A500. After selecting the puncture target in the ultrasonic image, the system will automatically rotate the ultrasonic transducer A2 and the puncture frame A700 to the plane where the puncture target is located, and give the number of the positioning groove A621. The puncture guide A7 is manually rotated so that the protrusion A73 is stuck in the corresponding numbered positioning groove A621, so that the puncture guide A7 is aligned with the puncture target. The puncture needle A900 is inserted into the puncture guide hole A721 of the puncture guide A7 and inserted into the breast along the predetermined path. During the insertion process, the actual trajectory of the puncture needle A900 in the ultrasound image and the theoretical trajectory can be compared to confirm whether the puncture needle A900 reaches the predetermined position according to the predetermined trajectory. The puncture is accurate and efficient.

[0102] It should be noted that since the puncture needle A900 is relatively thin, it may bend or deflect when inserted into the tissue. For the sake of patient safety, it is extremely important to monitor the actual position of the puncture needle A900. If the puncture needle A900 bends within the image plane, the bending deformation can be monitored within the image plane. If the puncture needle A900 bends outside the image plane, it can be judged by whether the puncture needle A900 can be seen in the image. The bending deformation of the puncture needle A900 within the image plane can be corrected by fine-tuning the puncture guide A7. If the puncture needle A900 bends outside the image plane, it must be corrected by pulling out the puncture needle A900 and reinserting it.

[0103] It should also be noted that, in addition to the above-mentioned breast A1000 puncture, the ultrasound examination device can also be used in operations such as emission particle implantation, cryotherapy and radiofrequency ablation needle therapy, and can provide the precision requirements required for targeted treatment, which is no longer limited here.

[0104] In the ultrasonic inspection device provided in this embodiment, the 3D ultrasonic probe A400 can provide a three-dimensional ultrasonic image, and the puncture frame A700 rotates synchronously with the ultrasonic transducer A2 to ensure that the puncture path is always within the real-time scanning plane A800 of the ultrasonic transducer A2 (that is, the axis of the puncture guide hole A721 of the puncture guide A7 is always within the real-time scanning plane A800 of the ultrasonic transducer A2). At the same time, the position of the puncture guide A7 on the frame A6 can be manually adjusted to provide precise positioning for the puncture operation, improve the puncture efficiency and accuracy, reduce the operation time, reduce the difficulty of the operation, and achieve accurate, low-traumatic, simple and fast surgical treatment.

[0105] Embodiment 2:

[0106] The difference between this embodiment and the first embodiment is as follows:

[0107] See also Fig. 9 and Fig.10 As shown, the ultrasonic inspection device of this embodiment also includes a second driving member A8 and a second transmission mechanism A9. The second driving member A8 is disposed in the mounting shell A1, and the output end of the second driving member A8 is connected to the second transmission mechanism A9. The second transmission mechanism A9 is connected to a second main shaft A10, which extends out of the avoidance hole on the mounting shell A1 and is connected to the puncture frame A700. The second driving member A8 is preferably a motor.

[0108] The outputs of the second driving member A8 and the first driving member A3 are controlled at the same time, so as to control the puncture frame A700 to rotate synchronously with the ultrasonic transducer A2. When the puncture needle A900 is bent out of the image plane and cannot be seen in the ultrasonic image plane, the puncture needle A900 can be found by controlling only the first driving member A3 to start, that is, only the ultrasonic transducer A2 rotates, and the position of the image plane is changed, while the puncture needle A900 is not moving.

[0109] Exemplarily, the second transmission mechanism A9 is connected to the output end of the second driving member A8 through a gear. The second transmission mechanism A9 includes a worm, and a turbine is coaxially mounted on the second main shaft A10, and the worm drives the turbine to rotate. Obviously, in other embodiments, the second driving member A8 and the second transmission mechanism A9, as well as the second transmission mechanism A9 and the second main shaft A10, can be connected by a belt drive or a chain drive.

[0110] The second main axis A10 is preferably coaxial with the first main axis A4, so as to ensure that the puncture path on the puncture frame A700 is always on the real-time scanning plane A800 of the ultrasonic transducer A2.

[0111] Obviously, in other embodiments, the second driving member A8 and the second transmission mechanism A9 may also be disposed on the outside of the mounting shell A1 to ensure the sealing of the mounting shell A1 and improve the service life of the ultrasonic transducer A2.

[0112] Embodiment three:

[0113] The difference between this embodiment and the first embodiment is as follows:

[0114] See also Fig.11 and Fig.12 As shown, in the ultrasonic inspection device of this embodiment, the mounting shell A1 is slender. The mounting shell A1 includes a probe end shell A11 and a shell A12 that are connected. The probe end shell A11 includes a head and a sound-transmitting hollow rod.

[0116] Embodiment 4:

[0117] The difference between this embodiment and the first and third embodiments is as follows:

[0118] See also Fig.13 and Fig.14 As shown, the ultrasonic inspection device provided in this embodiment further includes a second main shaft A10. The output end of the first driving member A3 is drivingly connected to the first main shaft A4 and the second main shaft A10 at the same time.

[0119] Specifically, the output end of the first driving member A3 is directly connected to the first main shaft A4. The output end of the first driving member A3 is connected to the second main shaft A10 through a belt transmission. The second main shaft A10 extends out of the mounting shell A1 and is in transmission connection with the puncture frame A700.

[0120] The portion of the second main shaft A10 extending out of the mounting shell A1 is coaxially mounted with an external gear A20, which is meshed with an internal gear A30, and the outer peripheral wall of the internal gear A30 is fixedly connected to the puncture frame A700. The second main shaft A10 drives the external gear A20 to rotate through the internal gear A30, and the external gear A20 further drives the puncture frame A700 to rotate.

[0121] In this embodiment, a clearance opening is provided on the probe end housing A11 corresponding to the internal gear A30. Obviously, in other embodiments, the size of the internal gear A30 or the probe end housing A11 and related structures can be adjusted to avoid interference between the internal gear A30 and the probe end housing A11, and the probe end housing A11 does not need to provide a clearance opening to improve sealing.

[0122] In addition, compared with the connection block A80 in the third embodiment extending from the sound-transparent hollow rod of the probe end shell A11, a second main shaft A10 is provided in this embodiment to extend out of the mounting shell A1 to achieve connection with the puncture frame A700. This embodiment is more convenient to set sealing devices such as sealing rings and has better sealing performance.

[0123] Embodiment five:

[0124] The difference between this embodiment and the fourth embodiment is:

[0125] See also Fig.15 As shown, the ultrasonic inspection device provided in this embodiment also includes a second driving member A8 and a second main shaft A10 disposed in the housing A12. The second driving member A8 is preferably a motor. The second main shaft A10 is coaxially connected to the output shaft of the second driving member A8. The second main shaft A10 extends out of the housing A12 and is transmission-connected to the puncture frame A700. Specifically, the portion of the second main shaft A10 extending out of the mounting shell A1 is coaxially mounted with an external gear A20, and the external gear A20 is meshed with an internal gear A30, and the internal gear A30 is fixedly connected to the puncture frame A700. The second main shaft A10 drives the external gear A20 to rotate through the internal gear A30, and the external gear A20 then drives the puncture frame A700 to rotate.

[0126] The ultrasonic transducer A2 and the puncture frame A700 rotate synchronously under the drive of the first driving member A3 and the second driving member A8 respectively. When the puncture needle A900 is bent out of the image plane and cannot be seen in the image plane, the puncture needle A900 can be found by controlling only the first driving member A3 to start, that is, only the ultrasonic transducer A2 rotates, changing the position of the image plane, while the puncture needle A900 is stationary.

[0130] Exemplarily, the ultrasonic transducer A2 is a convex array ultrasonic transducer A2. The center line of the scanning plane A800 of the ultrasonic transducer A2 is perpendicular to and coplanar with the first principal axis A4. Obviously, the scanning area of ​​the ultrasonic transducer A2 of this embodiment is different from the scanning area of ​​the ultrasonic transducer A2 of the third embodiment.

[0131] The puncture frame A700 is connected to the first main axis A4 through a connecting rod, and the puncture frame A700 and the ultrasonic transducer A2 swing synchronously around the first main axis A4. The puncture guide hole A721 on the puncture frame A700 forms an angle with the center line of the scanning plane A800 of the ultrasonic transducer A2. The axis of the puncture guide hole A721 on the puncture frame A700 forms an angle with the axis of the sound-transmitting hollow rod of the probe end housing A11, so as to adjust the occupied space of the entire ultrasonic inspection device so that the ultrasonic inspection device can adapt to different surgical operation spaces.

[0143] The puncture guide A7 is provided with a plurality of puncture guide holes A721 of different sizes and arranged in parallel, each of which corresponds to a letter.
