Description

Technical Field

[0001] This utility model relates to the field of ultrasonic therapy equipment technology, and in particular to an imaging adjustment structure and its ultrasonic therapy head device. Background Technology

[0002] Ultrasonic cavitation mechanical ablation therapy, based on high-intensity focused ultrasound (HIFU) technology, is a novel non-invasive treatment technique that has emerged in recent years. Its main principle is to utilize high-intensity, low-duty-cycle pulsed energy applied to the target tissue. Through extremely short, intense bursts of acoustic energy, controlled cavitation is induced within the focal volume. This cavitation is formed by microbubbles, and the violent expansion and collapse of these microbubbles mechanically homogenizes the cellular and tissue structures within the focal volume, transforming them into cell-free fluids or subcellular structures, thereby achieving the therapeutic goal. Currently, ultrasonic cavitation technology shows great promise in the treatment of tumors and thrombosis.

[0003] During ultrasonic cavitation therapy, it is necessary to monitor the treatment effect. Therefore, an imaging head is installed inside the ultrasonic treatment head, which moves with the ultrasonic treatment head to provide real-time imaging. However, since the height of the ultrasonic treatment head needs to be determined according to specific circumstances, the existing imaging head is fixed inside the ultrasonic treatment head without adjustment. This means that the imaging head may not be at the most suitable height for imaging, which will affect the imaging effect. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order; the cold water mentioned in the specification and claims of this invention includes room temperature water.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Reference Figures 1 to 5 , Figure 8 and Figure 9 The first embodiment of this application proposes an imaging adjustment structure, which includes: an imaging mounting component 400 and a lifting drive assembly 500 disposed on an external housing 100; the imaging mounting component 400 is used to fix the imaging assembly 300.

[0036] The housing 100 is provided with an imaging mounting hole, and the imaging mounting member 400 is slidably inserted into the imaging mounting hole. One end of the imaging mounting member 400 passes through the entrance of the imaging mounting hole to be connected and fixed to the driving end of the lifting drive assembly 500. The lifting drive assembly 500 drives the imaging mounting member 400 to rise or fall within the imaging mounting hole.

[0037] Specifically, the lifting drive assembly 500 drives the imaging mount 400 to rise or fall within the imaging mount hole, indirectly causing the imaging end of the imaging assembly 300 to rise closer to the outlet of the imaging mount hole or fall away from the outlet of the imaging mount hole.

[0038] In this embodiment, the imaging mount 400, the lifting drive assembly 500, and the imaging assembly 300 are mounted using the housing 100. The external ultrasonic transducer 200 is used to perform non-invasive treatment on the target location; the imaging assembly 300 then images the treated target to obtain post-treatment information, thus detecting the treatment effect. For individual treatment areas at the target location that are small or far from the imaging end of the imaging assembly 300, the lifting drive assembly 500 lowers and slides the imaging mount 400 within the imaging mount hole, indirectly causing the imaging assembly 300 to lower and slide. This allows the imaging end of the imaging assembly 300 to gradually approach the target location, enabling the imaging assembly 300 to acquire a clearer image of the treatment status at the target location. Alternatively, if the imaging end of the imaging component 300 is too close to the target position, it may not be able to fully capture the designated treatment area of ​​the target position. By driving the lifting drive component 500 to rise, the imaging mount 400 slides upward within the imaging mount hole, which indirectly causes the imaging component 300 to rise and slide. This allows the imaging end of the imaging component 300 to gradually move away from the target position, thereby enabling the imaging component 300 to acquire a clear and comprehensive image of the treatment situation at the target position.

[0039] In summary, the imaging adjustment structure enables arbitrary adjustment of the height of the imaging component 300, so that the imaging component 300 can adjust the imaging distance to obtain a clearer and more comprehensive image of the treatment situation.

[0040] Furthermore, in this embodiment, the imaging mount 400 is hollow along the radial direction, reducing the material used in the imaging mount 400. The imaging assembly 300 is inserted and fixed into the hollow hole of the imaging mount 400.

[0041] Reference Figures 1 to 5 ,and Figure 9 The imaging adjustment structure further includes a rotation drive assembly 600. The imaging mounting component 400 is provided with a keyhole 420. The rotation drive assembly 600 includes a rotation drive component 610 and a second gear 640. The rotation drive component 610 is fixed to the housing 100. The drive end of the rotation drive component 610 is driven to connect to the second gear 640. The second gear 640 is sleeved on the imaging mounting component 400. The internal part of the second gear 640 is vertically and retractably embedded in the keyhole 420. The rotation drive component 610 drives the second gear 640 to rotate the imaging mounting component 400 within the imaging mounting hole, thereby indirectly causing the imaging component 300 to rotate around the hole axis of the imaging mounting hole. The lifting direction of the second gear 640 relative to the keyhole 420 is parallel to and opposite to the lifting direction of the imaging mounting component 400.

[0042] In this embodiment, the rotation drive assembly 600 drives the rotation of the imaging mount 400, indirectly causing the imaging assembly 300 to rotate around the hole axis of the imaging mount hole. With the imaging end of the imaging assembly 300 oriented horizontally, the imaging assembly 300 can capture images of the target location from all angles, acquiring a comprehensive horizontal treatment view of the target location. Combined with the lifting drive assembly 500, the imaging assembly 300 can simultaneously acquire clear and vertically comprehensive treatment views. Then, through the keyhole 420, and the fact that a portion of the second gear 640 is liftably embedded within the keyhole 420, it is ensured that the driving of the rotation drive assembly 600 and the lifting drive assembly 500 do not interfere with each other.

[0043] Reference Figures 1 to 4 ,and Figure 9 The lifting drive assembly 500 includes a lifting drive component 510, a lifting guide rod 520, a lifting slide cylinder 530, and a lifting collar 540. The lifting drive component 510 is fixed to the housing 100. The driving end of the lifting drive component 510 is connected to and fixed to one end of the lifting guide rod 520 and drives the lifting guide rod 520 to rotate. The lifting slide cylinder 530 is slidably sleeved on the lifting guide rod 520. The outer wall of the lifting collar 540 is fixed to the lifting slide cylinder 530. The lifting collar 540 is sleeved and fixed to the imaging mounting component 400.

[0044] In this embodiment, the lifting drive component 510 drives the lifting guide rod 520 to rotate, causing the lifting slide cylinder 530 to move up and down along the rod axis of the lifting guide rod 520. Through the lifting slide cylinder 530, the lifting collar 540, and the imaging mount 400, the imaging assembly 300 is indirectly moved up and down. The lifting collar 540 is sleeved and fixed to the outside of the imaging mount 400. When the lifting drive component 500 indirectly drives the lifting collar 540 to move up and down, the imaging mount 400 rises smoothly, avoiding local height deviations during the ascent. Specifically, it prevents the connection point between the imaging mount 400 and the lifting collar 540 from being higher than the position of the imaging mount 400 that is far from the lifting collar 540.

[0045] Specifically, the lifting guide rod 520 has threads on its peripheral wall, and the lifting cylinder 530 has threads in its bore corresponding to the threads on the lifting guide rod 520. The threaded connection of the lifting cylinder 530's bore to the peripheral wall of the lifting guide rod 520 allows the lifting cylinder 530 to move vertically only along the axis of the lifting guide rod 520, thanks to the aforementioned threads and the radial position restriction of the lifting collar 540. This prevents the lifting cylinder 530 from rotating around the lifting guide rod 520, thus facilitating the vertical movement of the lifting collar 540 using the lifting cylinder 530.

[0046] In other embodiments, the lifting drive assembly 500 is provided in two or more sets and is evenly distributed around the circumference of the imaging mount 400. This further improves the smoothness of the lifting of the imaging mount 400.

[0047] Reference Figures 1 to 4 ,and Figure 9 The rotary drive assembly 600 further includes a rotary guide rod 620 and a first gear 630; the driving end of the lifting drive component 510 is connected and fixed to one end of the rotary guide rod 620 and drives the rotary guide rod 620 to rotate; the first gear 630 is sleeved on the rotary guide rod 620, and the first gear 630 is meshed with the second gear 640.

[0048] In this embodiment, the rotary drive 610 drives the rotary guide rod 620 to rotate, which in turn drives the first gear 630 to rotate. Through meshing with the first gear 630, the second gear 640 rotates, which in turn drives the imaging mount 400 to rotate, thereby causing the imaging assembly 300 to rotate. Furthermore, the meshing connection between the first gear 630 and the second gear 640 improves the rotational stability of the imaging mount 400.

[0049] In other embodiments, there are two or more rotary drive members 610, with rotary guide rods 620 and first gears 630 corresponding to each other. Two or more first gears 630 are evenly distributed around the second gear 640 and are all meshed with it. This further improves the rotational stability of the imaging mount 400.

[0050] Reference Figures 1 to 4 ,and Figure 9 The imaging mounting component 400 has a first toothed groove 410 on its outer wall, and the lifting collar 540 includes a first collar 541 and a second collar 542. The outer wall of the first collar 541 is fixed to the lifting slide cylinder 530. The outer wall of the second collar 542 has an annular groove 5421, and its inner wall has a second toothed groove 5422. The first collar 541 is fitted inside the annular groove 5421, and the first collar 541 is located between the top side wall and the bottom side wall of the annular groove 5421. The second collar 542 is fitted onto the imaging mounting component 400, and the second toothed groove 5422 is fastened to the first toothed groove 410.

[0051] In this embodiment, the imaging mounting component 400 and the second collar 542 are fastened together using the first groove 410 and the second groove 5422. Then, the first collar 541 is fitted into the collar groove 5421 to connect the first collar 541 and the second collar 542. This ensures that the first collar 541 can drive the second collar 542 to move up and down, and also avoids the lifting drive of the lifting drive component 500 from affecting the rotation drive of the rotation drive component 600.

[0052] Reference Figures 1 to 4 ,and Figure 9 Further based on this embodiment, the first collar 541 is provided with a first sleeve hole 5411 and a second sleeve hole 5412. The first sleeve hole 5411 is fitted and fixed to the imaging mounting component 400, and the second sleeve hole 5412 is fitted and fixed to the lifting slide cylinder 530. The first collar 541 is also provided with a plurality of first screw holes (not shown in the figure). The first screw holes are evenly distributed around the second sleeve hole 5412. The lifting slide cylinder 530 is provided with corresponding second screw holes 531. The first screw holes and the second screw holes 531 are arranged in a one-to-one correspondence and face each other. The first screw holes and the second screw holes 531 cooperate to further fix the first collar 541 and the lifting slide cylinder 530.

[0053] Reference Figures 1 to 4 ,and Figure 9 The inner ring wall of the second gear 640 is provided with a protruding rib 641, which is vertically and retractably embedded in the key hole 420. The lifting direction of the protruding rib 641 is parallel to and opposite to the lifting direction of the imaging mount 400 relative to the key hole 420.

[0054] In this embodiment, the protruding ridge 641 and keyhole 420 are used to ensure that the second gear 640 can drive the imaging mounting component 400 to rotate, and also to ensure that the imaging mounting component 400 can move up and down under the indirect drive of the lifting drive component 510, so that the rotational movement and the lifting movement of the imaging mounting component 400 can be realized and carried out simultaneously.

[0055] Reference Figures 1 to 10 Another embodiment of this utility model provides an ultrasonic therapy head device, which includes the above-mentioned imaging adjustment structure, ultrasonic transducer 200 and the housing 100; the ultrasonic transducer 200 is fixed to the bottom of the housing 100 and located at the outlet of the imaging mounting hole.

[0056] In this embodiment, the imaging adjustment structure and the ultrasonic transducer unit 200 are mounted using the housing 100. The imaging assembly 300 is indirectly driven to move vertically and rotate relative to the ultrasonic transducer unit 200 using the lifting drive assembly 500 and the rotation drive assembly 600 of the imaging adjustment structure, enabling the imaging assembly 300 to acquire a clear and comprehensive image of the treatment situation at the target location.

[0057] Specifically, several of the ultrasonic transducer units 200 are arranged in an array. The array mounting of the ultrasonic transducer units 200 is achieved using the housing 100, enabling the ultrasonic treatment head to achieve the effect of high-intensity focused ultrasound.

[0058] Reference Figures 1 to 3 , Figure 6 , Figures 8 to 10 Further based on this embodiment, the shell 100 includes an inner shell 110 and an outer shell 120; the inner shell 110 includes a first inner cylinder 111 and a second inner cylinder 112, and the outer shell 120 is provided with an accessory mounting cavity 121; the first inner cylinder 111 is provided with a first inner cylinder hole 1111, and the imaging mounting component 400 is slidably inserted into the first inner cylinder hole 1111, the hole axis of the first inner cylinder hole 1111 is parallel to the lifting direction of the imaging mounting component 400; one end of the first inner cylinder 111 is embedded in the accessory mounting cavity 121, one end of the second inner cylinder 112 is fixed to the other end of the first inner cylinder 111, and the other end of the second inner cylinder 112 is detachably fitted into the cavity opening fixed to the accessory mounting cavity 121;

[0059] The power signal terminal of the ultrasonic transducer 200 passes through the second inner cylinder 112 and is located inside the accessory mounting cavity 121.

[0060] Specifically, the imaging mounting hole is the first inner cylinder hole 1111.

[0061] In this embodiment, the first inner cylinder hole 1111 of the first inner cylinder 111 is used to radially limit the imaging mounting component 400, and also restricts the imaging mounting component 400 to move up and down only along the axial direction of the first inner cylinder hole 1111, thereby improving the smoothness of the lifting and lowering of the imaging mounting component 400. The second inner cylinder 112 is used to realize the array installation of the ultrasonic transducer unit 200, and the power signal terminal of the ultrasonic transducer unit 200 is set in the accessory mounting cavity 121 to realize the closed connection between the power signal line of the ultrasonic transducer unit 200 and the ultrasonic treatment head device, so as to avoid moisture or dust at the connection between the ultrasonic transducer unit 200 and the power signal line.

[0062] Furthermore, the second inner cylinder 112 and the accessory mounting cavity 121 of the outer shell 120 can be detachably fitted together, thereby achieving the fitting and fixing of the second inner cylinder 112 and the outer shell 120. This not only achieves the closed setting of the accessory mounting cavity 121, but also facilitates the installation of accessories such as the imaging mounting component 400, the lifting drive component 500, and the rotating component into the accessory mounting cavity 121.

[0063] Reference Figures 1 to 3 , Figures 8 to 10Further, based on this embodiment, the outer shell 120 includes a first outer cylinder 122, a second outer cylinder 123, and a third outer cylinder 124; the bottom end of the first outer cylinder 122 is detachably fitted to the top end of the second outer cylinder 123, the bottom end of the second outer cylinder 123 is detachably fitted to the top end of the third outer cylinder 124, and the bottom end of the third outer cylinder 124 is detachably fitted to the second inner cylinder 112. The accessory mounting cavity 121 is formed by the first outer cylinder 122, the second outer cylinder 123, and the third outer cylinder 124.

[0064] In this embodiment, the outer casing 120 is also made detachable, which further facilitates the installation of accessories in the accessory mounting cavity 121.

[0065] Reference Figure 3 and Figure 10 The second outer cylinder 123 is provided with a wire outlet hole 1231, which is used to lead out the control lines of the imaging component 300, the lifting drive component 510, the rotating drive component 610 and the ultrasonic transducer unit 200.

[0066] Reference Figure 10 Furthermore, based on this embodiment, the outer wall of the first outer cylinder 122 is provided with a handle 800 for easy gripping by the user.

[0067] Reference Figures 1 to 2 , Figures 6 to 10 Furthermore, based on this embodiment, the second inner cylinder 112 is provided with a second inner cylinder hole 1121, the top end of which is connected to the first inner cylinder hole 1111. The diameter of the top end of the second inner cylinder hole 1121 is smaller than the diameter of the bottom end. The diameter of the second inner cylinder hole 1121 gradually decreases along the direction from the top end to the bottom end. This results in high focusing power for the ultrasonic transducer unit 200 mounted on the second inner cylinder 112. The imaging end of the imaging assembly 300 is located inside the second inner cylinder hole 1121.

[0068] Reference Figure 1 , Figure 2 , Figure 6 and Figure 9 Furthermore, the second inner cylinder 112 is a cylindrical structure with a dome-shaped cross-section. Specifically, the second inner cylinder 112 is embedded in the accessory mounting cavity 121, and the second inner cylinder 112 protrudes towards the first inner cylinder hole 1111.

[0069] Reference Figures 1 to 3 , Figure 6 , Figure 8 and Figure 9Furthermore, sealing rings 700 are provided at the fitting connection between the first outer cylinder 122 and the second outer cylinder 123, the fitting connection between the second outer cylinder 123 and the third outer cylinder 124, and the fitting connection between the third outer cylinder 124 and the second inner cylinder 112. While achieving fitting and fixing, the sealing effect of the fitting connection is ensured, preventing external moisture from entering the accessory installation cavity 121 from the fitting connection.

[0070] Reference Figures 1 to 2 , Figure 6 ,and Figure 9 Furthermore, the second inner cylinder 112 has several ultrasonic mounting holes 1122 on its cylinder wall. The ultrasonic transducer unit 200 is set in a one-to-one correspondence with the ultrasonic mounting hole 1122. The control end of the ultrasonic transducer unit 200 passes through the ultrasonic mounting hole 1122 and is located in the accessory mounting cavity 121.

[0071] Reference Figure 7 Furthermore, the peripheral wall of the ultrasonic transducer unit 200 is provided with a sealing connection groove 210. The sealing connection groove 210 is L-shaped, with one wall abutting against the wall of the ultrasonic mounting hole 1122 and the other wall abutting against the outer wall of the second inner cylinder 112. Sealing rings 700 are also provided between one wall of the sealing connection groove 210 and the wall of the ultrasonic mounting hole 1122, and between the other wall of the sealing connection groove 210 and the outer wall of the second inner cylinder 112. This improves the sealing connection between the ultrasonic transducer unit 200 and the second inner cylinder 112.

The imaging mounting component 400 is rotatably and liftably inserted through the third mounting plate 150. The first gear 630 and the second gear 640 are both located between the second mounting plate 140 and the third mounting plate 150.

[0077] In this embodiment, the third mounting plate 150 is used to limit the upward offset of the first gear 630 and the second gear 640, so as to prevent either the first gear 630 or the second gear 640 from excessively offset upwards, thereby preventing the first gear 630 and the second gear 640 from disengaging from the transmission connection.

[0078] Reference Figures 1 to 2 , Figure 5 ,and Figure 9 The bottom surface of the third mounting plate 150 is provided with a guide ridge 151, and the top surface of the second gear 640 is provided with a guide groove 642. The guide groove 642 is arranged around the circumference of the second gear 640. The shape of the guide ridge 151 is adapted to the shape of the guide groove 642. The guide ridge 151 is slidably embedded in the guide groove 642. The rotation drive member 610 indirectly drives the second gear 640 to rotate, so that the guide groove 642 rotates along the guide ridge 151.

[0079] In this embodiment, the guide rib 151 and guide groove 642 are used to improve the rotational smoothness of the second gear 640 and prevent the second gear 640 from rotating off-center.
