Description

Technical Field

[0001] The utility model relates to ultrasonic focusing, and more particularly to a focused ultrasonic system. Background Art

[0002] Focused ultrasound (HIFU) ablation technology achieves the purpose of treating diseases by precisely focusing ultrasound within a target area to achieve ablation of the target tissue in a matrix. The ultrasound focusing treatment head disclosed in CN216319558U includes a shell, a water bag is provided at the bottom of the shell, and a sleeve is provided outside the shell. The shell can move longitudinally within the water bag. The disadvantage of this ultrasound treatment device is that the diameter of the water bag is small, and the contact area with the outer surface of the target object is also small, and the fit is not high. Secondly, because the coupling agent in the water bag is fluid, when the treatment head is rotated sideways, the treatment head cannot be completely immersed in the coupling agent. Therefore, the ultrasound of the treatment head is only suitable for irradiating downward from above, and cannot perform ultrasound ablation surgery on the target tissue from the side. Secondly, existing ultrasound treatment devices mostly require the operator to manually move the treatment head. At the same time, the operator must observe the display while moving the treatment head to coincide with the target position of the treatment plan, which increases the difficulty of surgical control.

The B-ultrasound probe 12 is located in the center of the treatment head 2, and the transducers 21 are arranged around the B-ultrasound probe 12. In this embodiment, the treatment head 2 includes five transducers 21. It should be understood that the number of transducers 21 is 3 or more. The transducers 21 have the same focal length, diameter, and curvature, and are focused on the same point, namely, the focal point 21A (see FIG. Figure 6 ).

[0023] like Figure 1 and Figure 4 As shown, the focused ultrasound system according to this embodiment also includes a motion mechanism 3, a control cabinet 4, and an ultrasonic controller 5. The motion end of the motion mechanism 3 is connected to the treatment head 2 to drive the treatment head 2 to move. The control cabinet 4 is communicatively connected to the ultrasonic image acquisition device 1 and the motion mechanism 3, and includes a control host 41 for controlling the transducers 21. The ultrasonic controller 5 is communicatively connected to the control host 41 to activate or deactivate the multiple transducers 21. In this embodiment, the motion mechanism 3 is a six-axis robotic arm, each of the six rotating shafts being equipped with a drive motor. The motion end of the six-axis robotic arm can move along the X-axis, Y-axis, and Z-axis. In this embodiment, the ultrasonic controller 5 is a foot switch for ultrasonic transmission. It should be understood that the control cabinet 4 also includes a motion control module for controlling the motion mechanism 3, as well as a high-frequency, high-voltage power supply and an isolation transformer connected to the transducers 21.

[0024] like Figure 1 and Figure 3 As shown, the focused ultrasound system according to this embodiment further includes a motion controller 6, which is communicatively connected to the control cabinet 4 to control the movement of the motion mechanism 3. In this embodiment, the motion controller 6 is a 5D mouse. It should be understood that the motion controller 6 can also be a joystick, etc.

[0025] like Figure 1 and Figure 3 As shown, the focused ultrasound system according to this embodiment further includes a display device 7 , which is communicatively connected to the control cabinet 4 to display the real-time ultrasound image of the target tissue P obtained by the ultrasound image acquisition device 1 and the target position of the treatment plan.

[0026] like Figure 1 and Figure 4 As shown, the focused ultrasound system according to this embodiment further includes a water bag 8, a bracket 9 and a treatment bed 10, wherein the water bag 8 for containing the coupling agent is installed on the bracket 9, and the bracket 9 is detachably connected to the treatment bed 10.

[0027] The water bag 8 is a flexible water bag. In this embodiment, the water bag 8 is made of silica gel. Figure 5 As shown, the lower end of the water bag 8 is connected to a drain pipe 81 to discharge the coupling agent as needed.

[0028] like Figure 4 and Figure 5 As shown, the bracket 9 is an arched bracket, including a transverse support plate 91, with two vertical support plates 92 connected to both ends of the transverse support plate 91. The transverse support plate 91 has a through hole 911, and the water bladder 8 is detachably connected to the through hole 911. In this embodiment, the upper end of the water bladder 8 has a hard ring structure, so that the weight of the water bladder 8 is supported by the transverse support plate 91.

A real-time image of the treatment head 2 is displayed on a display device 7, allowing the focus 21A of the treatment head 2 to quickly coincide with the target location in the treatment plan. A bracket 9, which holds the water bladder 8, positions the patient between the water bladder 8 and the treatment bed 10. The bracket 9 can be moved as needed, significantly facilitating the procedure. Because the treatment head 2 is separated from the water bladder 8, the size of the water bladder 8 is not limited by the treatment head 2. The water bladder 8 can be enlarged to fit the entire outer surface of the target tissue P, for example, to the width of the patient's body, depending on the treatment needs. The treatment head 2 can freely move and rotate within the large water bladder 8, enabling ultrasonic ablation of the target tissue P from the side. Furthermore, the separation of the treatment head 2 from the water bladder 8 makes it very convenient to replace the water bladder 8 and the coupling agent.
