Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to a bracket for an ultrasound probe and an ultrasound interventional device. Background Technology

[0002] Thermal ablation mainly uses high-frequency current, microwaves, or lasers to generate heat, which is then transferred to the ablation area through an ablation needle. This causes the water inside and outside the cells in the ablation area to evaporate, dry, shrink, and slough off, resulting in aseptic necrosis, thereby achieving the therapeutic purpose.

[0003] In ablation surgery, an ultrasound probe is typically used to guide the positioning of the ablation needle and observe the ablation area. Currently, ultrasound temperature imaging is one of the core technologies for achieving precise and safe treatment in ablation procedures. The primary function of ultrasound temperature imaging is to quantify and display the temperature distribution of the ablation area in real time. Ultrasound thermometry is widely used for temperature monitoring in thermal ablation therapy due to its non-invasive nature. However, individual differences in the thermal strain coefficient k of the same organ tissue among different patients can lead to deviations in ultrasound temperature measurement results, thus affecting the effectiveness of treatment. Therefore, researchers have proposed using a thermometer to monitor the temperature of the ablation area in real time to achieve real-time dynamic calibration of the thermal strain coefficient k in the ultrasound temperature image, thereby improving the accuracy of the ultrasound temperature image. However, in ablation surgery, operators typically need to hold the ultrasound probe in one hand and the ablation needle in the other, making it difficult to monitor the temperature of the ablation area using a thermometer. Summary of the Invention

[0004] The purpose of this application is to overcome the difficulty of using a temperature measuring needle to monitor the temperature of the ablation area in existing ablation procedures, where operators need to hold the ultrasound probe and ablation needle while performing the ablation operation.

[0005] Therefore, this application provides a support for an ultrasonic probe, comprising a support body adapted to be clamped on the ultrasonic probe, a first guide disposed on the support body, and a second guide disposed on the support body. When the support body is clamped on the ultrasonic probe, the first guide is located on the side of one end in the length direction of the ultrasonic probe, and the second guide is located on the side of one end in the width direction of the ultrasonic probe. Either the first guide or the second guide is used to guide an ablation needle, and the other of the first guide or the second guide is used to guide a temperature measuring needle. During ablation, the needle of the first guide is coplanar with the scanning surface of the ultrasonic probe, and the tip of the needle of the second guide is located within the scanning surface of the ultrasonic probe.

[0006] Furthermore, the support body includes two opposing short beams and two opposing long beams, which are connected to each other to form a support body that is fitted onto the ultrasound probe. A first guide is disposed on one of the short beams and a second guide is disposed on one of the long beams.

[0007] Furthermore, the second guide is detachably connected to the long beam of the support body.

[0008] Furthermore, the second guide includes a second base and a guide member disposed on the second base, the guide member having a second needle path through which a temperature measuring needle or an ablation needle passes.

[0009] Furthermore, the second base includes at least two substrates that are parallel to each other and arranged opposite to each other, and a connecting part connecting the two substrates. When the support body is clamped on the ultrasonic probe, the substrates are parallel to the acoustic window of the ultrasonic probe, and the connecting part is clamped between the long beam and the ultrasonic probe.

[0010] Furthermore, the guide includes guide posts respectively disposed on two substrates, the axes of the two guide posts being on the same straight line, each guide post being connected to a guide portion, each guide portion being provided with a needle hole for the temperature measuring needle to pass through, the axes of the needle holes on the two guide portions being on the same straight line, and the needle holes of the two guide portions forming a second needle path.

[0011] Furthermore, the guide is inclined on the substrate to accommodate the puncture depth of the temperature measuring needle.

[0012] Furthermore, the short beam opposite to the first guide is hinged to the long beam on which the second guide is mounted, the long beam opposite to the second guide is hinged to the short beam on which the first guide is mounted, and the short beam opposite to the first guide and the long beam opposite to the second guide are detachably connected by a locking member.

[0013] Furthermore, a support portion opposite to the connecting portion is also connected between the two substrates.

[0014] This application also provides an ultrasound interventional device, which includes an ultrasound probe and the aforementioned support for the ultrasound probe.

[0015] The aforementioned support for the ultrasound probe is clamped onto the ultrasound probe during ablation surgery. The operator can hold the ultrasound probe with one hand and insert the ablation needle into the ablation area with the other hand. Then, the temperature measuring needle is inserted into the edge of the ablation area to measure the temperature of the ablation area. The temperature measuring needle stably measures the temperature of the ablation area under the friction of the guide, thus enabling real-time monitoring of the temperature of the ablation area using the temperature measuring needle during ablation surgery. This allows for real-time dynamic calibration of the thermal strain coefficient k of the ultrasound temperature image, thereby improving the temperature accuracy of the ultrasound temperature image. Therefore, this application reduces the difficulty of accurately monitoring the temperature of the ablation area using the temperature measuring needle. Attached Figure Description

[0027] Example 1

[0028] Reference Figures 1-4 Embodiment 1 of this application provides a support for an ultrasonic probe, including a support body 1 suitable for clamping the ultrasonic probe, a first guide 2 disposed on the support body 1, and a second guide 3 disposed on the support body 1. When the support body 1 is clamped on the ultrasonic probe, the first guide 2 is located on the side of one end in the length direction of the ultrasonic probe, and the second guide 3 is located on the side of one end in the width direction of the ultrasonic probe. Either the first guide 2 or the second guide 3 is used to guide an ablation needle 4, and the other of the first guide 2 and the second guide 3 is used to guide a temperature measuring needle 5. During ablation, the needle of the first guide 2 is coplanar with the scanning surface of the ultrasonic probe, and the tip of the needle of the second guide 3 is located within the scanning surface of the ultrasonic probe. The scanning surface of the ultrasonic probe refers to the two-dimensional ultrasonic imaging plane formed by the emission and reception of sound waves when the ultrasonic probe is in contact with the human body.

[0029] The operator clamps the aforementioned support for the ultrasound probe onto the ultrasound probe. During the ablation procedure, the operator can hold the ultrasound probe with one hand and insert the ablation needle 4 into the ablation area with the other hand. Then, the temperature measuring needle 5 is inserted into the edge of the ablation area to measure the temperature of the ablation area. The temperature measuring needle 5 stably measures the temperature of the ablation area under the frictional force of the guide, thus enabling the temperature of the ablation area to be monitored in real time during the ablation procedure using the temperature measuring needle 5. This allows for real-time dynamic calibration of the thermal strain coefficient k of the ultrasound temperature image, thereby improving the temperature accuracy of the ultrasound temperature image. Therefore, this application reduces the difficulty of accurately monitoring the temperature of the ablation area using the temperature measuring needle 5.

[0030] Specifically, the ablation area is the location of the lesion to be ablated. The first guide 2 guides the ablation needle 4, and the second guide 3 guides the thermometer needle 5. Guiding the ablation needle 4 via the first guide 2 allows for real-time observation of the entire needle shaft and tip, facilitating medical personnel's observation of the needle's insertion and the ablation process of the lesion. Alternatively, placing the ablation needle 4 on the second guide 3 also allows for observation of the needle tip's position relative to the lesion and the ablation process itself.

[0031] Reference Figure 1 and Figure 2 The support body 1 is positioned close to the scanning end of the ultrasound probe when clamped onto it. The support body 1 includes two opposing short beams 11 and two opposing long beams 12. The long beams 12 and short beams 11 are interconnected to form the support body 1, which is fitted onto the ultrasound probe. A first guide 2 is disposed on one of the short beams 11, and a second guide 3 is disposed on one of the long beams 12. The first guide 2 and the second guide 3 are arranged adjacent to each other. Specifically, the two opposing long beams 12 and the two opposing short beams 11 are interconnected to form an approximately rectangular support. The curvature of the two long beams 12 is similar to the curvature of the sides at both ends of the ultrasound probe in the width direction, and the curvature of the two short beams 11 is similar to the curvature of the sides at both ends of the ultrasound probe in the length direction. Matching the curvature of the long beams 12 and short beams 11 with the curvature of the sides of the ultrasound probe improves the firmness of the connection between the support body 1 and the ultrasound probe.

[0032] Reference Figure 1 and Figure 2 The short beam 11 opposite to the first guide 2 is hinged to the long beam 12 on which the second guide 3 is mounted. The long beam 12 opposite to the second guide 3 is hinged to the short beam 11 on which the first guide 2 is mounted. The short beam 11 opposite to the first guide 2 and the long beam 12 opposite to the second guide 3 are detachably connected by the locking member 6. With this configuration, when the bracket body 1 is installed on the ultrasound probe, the connection between the short beam 11 opposite to the first guide 2 and the long beam 12 opposite to the second guide 3 is disengaged by opening the locking member 6. The short beam 11 opposite to the first guide 2 and the long beam 12 opposite to the second guide 3 are rotated to wrap the bracket body 1 around the ultrasound probe. Then, the short beam 11 opposite to the first guide 2 and the long beam 12 opposite to the second guide 3 are locked by the locking member 6, thereby clamping the bracket for the ultrasound probe onto the ultrasound probe, facilitating the connection between the bracket body 1 and the ultrasound probe.

[0033] Reference Figure 1 and Figure 2The locking component 6 includes a rotating rod 61 rotatably connected to the end of the long beam 12 opposite to the second guide 3. The rotating rod 61 rotates about an axis perpendicular to the acoustic window of the ultrasonic probe, which is the side of the ultrasonic probe that contacts the human body. The rotating rod 61 is located at the end of the long beam 12 opposite to the second guide 3 away from the first guide 2. The free end of the rotating rod 61 is threaded with a locking cap 62. The short beam 11 opposite to the first guide 2 is provided with a slot 121 for the rotating rod 61 to be inserted. The slot 121 is set facing the long beam 12 opposite to the second guide 3. When the bracket body 1 is clamped on the ultrasonic probe, the rotating rod 61 is rotated to be inserted into the slot 121. Then the locking cap 62 is rotated to press against the short beam 11 opposite to the first guide 2, thereby locking the short beam 11 opposite to the first guide 2 and the long beam 12 opposite to the second guide 3.

[0034] Reference Figures 2-4 The second guide 3 is detachably connected to the long beam 12 of the support body 1. By detachably connecting the second guide 3 to the long beam 12 of the support body 1, it is convenient to replace and maintain the second guide 3.

[0035] Reference Figures 2-4 The second guide 3 includes a second base 31 and a guide member 32 disposed on the second base 31. The guide member 32 is provided with a second needle channel through which the temperature measuring needle 5 passes. When the temperature measuring needle 5 is installed on the second guide 3, it is fixed in the second needle channel by friction with the second needle channel.

[0036] Specifically, refer to Figures 2-4 The second base 31 includes at least two substrates 311 that are parallel to each other and arranged opposite to each other, and a connecting part 312 that connects the two substrates 311. When the support body 1 is clamped on the ultrasonic probe, the substrates 311 are parallel to the surface of the ultrasonic probe’s acoustic window, and the connecting part 312 is clamped between the long beam 12 of the support body 1 and the ultrasonic probe.

[0037] In some embodiments, refer to Figures 2-4To facilitate the installation of the second guide 3, the height of the connecting part 312 is greater than or equal to the height of the long beam 12 used to install the second guide 3. When installing the second guide 3, the short beam 11 opposite to the first guide 2 and the long beam 12 used to install the second guide 3 are sequentially passed through the gap between the two bases, so that the second guide 3 is positioned on the long beam 12. The locking member 6 is opened to clamp the bracket body 1 onto the ultrasonic probe. Tightening the locking member 6 clamps the connecting part 312 between the side of the ultrasonic probe and the long beam 12, thereby fixing the second guide 3. Specifically, the shape of the connecting part 312 is adapted to the shape of the side of the ultrasonic probe at one end in the width direction that is in contact with the connecting part 312, improving the firmness of the second guide 3's connection to the bracket body 1.

[0038] Specifically, refer to Figures 2-4 A support portion 7, opposite to the connecting portion 312, is connected between the two substrates 311. The connecting portion 312 and the support portion 7 are located at opposite ends of the substrates 311. The support portion 7 improves the stability of the connection between the two substrates 311 and reduces the possibility of shaking between the two substrates 311 due to the lack of a support portion 7 when the temperature probe 5 passes through the second needle path into the ablation area. The connecting portion 312 may also have an opening (not shown in the figure). The opening extends through the connecting portion 312 in a direction parallel to the length of the long beam 12, and the height of the opening is less than the height of the long beam 12. The substrates 311, connecting portion 312, and support portion 7 of the guide are all made of a rigid material with a certain degree of elasticity. When connecting the second guide 3, the opening can be slightly pried open and fitted onto the long beam 12, and then the connecting portion 312 is clamped between the ultrasonic probe and the long beam 12 to install the second guide 3.

[0039] Reference Figure 3 and Figure 4 The guide member 32 includes guide posts 321 respectively disposed on two base plates 311. The axes of the two guide posts 321 are on the same straight line. Each guide post 321 is connected to a guide portion 322, which is inserted into the guide post 321. Each guide portion 322 is provided with a needle hole 3221 for the temperature measuring needle 5 to pass through. The axes of the needle holes 3221 on the two guide portions 322 are on the same straight line, and the needle holes 3221 on the two guide portions 322 are interconnected to form a second needle channel. Specifically, the two guide posts 321 are centrally symmetrically arranged. Each guide post 321 is provided with a slot 3211, which extends along the axial direction of the guide post 321. Each guide portion 322 has a protrusion 3222 on its side wall for engaging with the slot 3211 of the corresponding guide post 321. When the guide portion 322 is installed on the guide post 321, the protrusion 3222 engages with the slot 3211.

[0040] Specifically, the guide 32 is inclined on the substrate 311 to accommodate the puncture depth of the temperature measuring needle 5. Specifically, during the manufacturing of the second guide 3, the angle between the guide 32 and the substrate 311 of the second guide 3 can be changed to produce a second guide 3 with a different angle between the second needle path and the substrate 311. When the angle between the second needle path and the substrate 311 is different, the depth to which the temperature measuring needle 5 penetrates into the patient's skin is also different. The operator can select a second guide 3 with a different puncture depth according to the needs.

[0041] Reference Figure 1 and Figure 2 The first guide 2 includes a first base 21 connected to the short beam 11 and a first needle channel 22 disposed on the first base 21, the first needle channel 22 being used to guide the ablation needle 4. The first base 21 is rotatably disposed on the short beam 11 to change the puncture depth of the ablation needle 4.
