[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the relevant medical auxiliary equipment used by the inventors of the present invention when treating the thyroid gland with high-intensity focused ultrasound is first introduced.

[0037] Related medical auxiliary equipment includes auxiliary straps and multiple auxiliary pads of varying thicknesses. When using this equipment for high-intensity focused ultrasound (HIFU) treatment of the thyroid gland, one or more auxiliary pads are placed on the treatment bed, and the patient lies prone on the bed and the pads. The treatment bed has a first treatment port, below which the HIFU treatment head can be positioned. The position and number of auxiliary pads can then be adjusted to elevate the patient's waist to chest, raising the shoulders. An auxiliary strap can be used to support the patient's chin, with both ends connected and suspended to elevate the head, thus suspending the neck above the first treatment port and the treatment head, exposing the thyroid lesion area to the treatment range. A water-sealing garment is then placed between the patient's chin and the auxiliary strap, between the waist to chest and the auxiliary pads, and between the chest to the neck and the treatment bed. This garment has a second treatment port corresponding to the first treatment port. The garment then wraps around the patient's waist to shoulders and head, allowing the chest to neck to be submerged in water without leakage. Afterwards, the treatment head can be used to perform high-intensity focused ultrasound treatment on the thyroid lesion area.

[0038] However, when using related medical auxiliary equipment for high-intensity focused ultrasound (HIFU) treatment of the thyroid gland, adjusting the height of the head elevation requires adjusting the connection length at both ends of the auxiliary strap to adjust the height the strap supports the head. Adjusting the shoulder height requires increasing or decreasing the number of auxiliary pads and adjusting the overall thickness of the pads below the patient to adjust the height the pads support the shoulders. This makes shoulder and head adjustments inconvenient. Furthermore, due to varying patient body shapes, the adjustment limitations of the auxiliary straps and pads in the related medical auxiliary equipment are significant. For example, the maximum connection length at the joint of the auxiliary strap may be short, or the thickness of multiple auxiliary pads may not be able to be combined to achieve an appropriate thickness. This can obscure the thyroid lesion area, hindering complete exposure of the thyroid lesion area and consequently affecting the accuracy of HIFU treatment of the thyroid lesion area.

[0039] The medical auxiliary device provided by the present invention will now be described in detail with reference to the accompanying drawings.

[0040] like Figures 1-6 As shown, this embodiment of the invention provides a medical assistive device 100, including a first support adjustment structure 1 and / or a second support adjustment structure 2. The first support adjustment structure 1 includes a first support body 11 and a first adjustment component. The first support body 11 is used to support the head, and the first adjustment component is connected to the first support body 11 to adjust the height of the first support body 11. The second support adjustment structure 2 includes a second support body and a second adjustment component 22. The second support body is used to support the torso, and the second adjustment component 22 is connected to the second support body to adjust the height of the second support body.

[0041] The medical auxiliary device 100 provided in this embodiment of the invention, when used to treat thyroid diseases, allows the patient 300 to lie prone on the first support adjustment structure 1 and / or the second support adjustment structure 2. The head can be supported by the first support body 11, and the height of the head supported by the first support body 11 can be adjusted by adjusting the height of the first support body 11 using the first adjustment component. That is, the head can be supported by the first support adjustment structure 1, and the height of the head supported can be adjusted. And / or, the shoulders can be supported by the second support body by supporting the torso, and the height of the torso supported by the second support body can be adjusted by adjusting the height of the second support body using the second adjustment component 22, thereby adjusting the height of the shoulders supported by the second support body. That is, the shoulders can be supported by supporting the torso using the second support adjustment structure 2, and the height of the shoulders supported can be adjusted by adjusting the height of the torso. This makes the adjustment of the height of the shoulders and / or the head convenient, which is beneficial for the complete exposure of the thyroid lesion area, and thus improves the accuracy of high-intensity focused ultrasound treatment of the thyroid lesion area.

[0042] Taking the medical auxiliary device 100 provided in this embodiment of the invention, which includes a first support adjustment structure 1 and a second support adjustment structure 2, as an example, in practical applications, when using the medical auxiliary device 100 provided in this embodiment of the invention to perform high-intensity focused ultrasound treatment on the thyroid gland, the first support adjustment structure 1 and the second support adjustment structure 2 can be placed on the treatment bed 200, and the patient 300 can lie prone on the treatment bed 200 and the first support adjustment structure 1 and the second support adjustment structure 2. The treatment bed 200 has a first treatment port 201, and a high-intensity focused ultrasound treatment head can be provided below the first treatment port 201. At this point, the first support body 11 supports the patient's head, and the second support body supports the patient's shoulders by supporting the patient's torso. Then, the height of the first support body 11 supporting the head can be adjusted by using the first adjustment component, and the height of the second support body supporting the torso can be adjusted by using the second adjustment component 22, thus adjusting the height of the second support body supporting the shoulders. This allows the patient's neck to be suspended above the first treatment port 201 and the treatment head, exposing the thyroid lesion area to the treatment range of the treatment head. Next, a water-sealing garment can be placed between the patient's head and the first support body 11, between the patient's torso and the second support body, and between the patient's torso and the treatment bed 200. The water-sealing garment has a second treatment port corresponding to the first treatment port 201. The water-sealing garment can then wrap around the patient's torso and head, allowing the patient's chest to neck to be immersed in water without leakage. Afterwards, the treatment head can be used to perform high-intensity focused ultrasound treatment on the thyroid lesion area.

[0043] However, the medical auxiliary device 100 provided in this embodiment of the invention is not limited to the use of the first support adjustment structure 1 and the second support adjustment structure 2 together. For example, the first support adjustment structure 1 can also be used in conjunction with the auxiliary pad in the related technology, or the second support adjustment structure 2 can be used in conjunction with the auxiliary belt in the related technology. Compared with the auxiliary belt in the related technology, the first support adjustment structure 1 makes the adjustment of head height more convenient, and compared with the auxiliary pad in the related technology, the second support adjustment structure 2 makes the adjustment of shoulder height more convenient. Therefore, the use of the first support adjustment structure 1 and / or the second support adjustment structure 2, compared with the use of related technologies, can both facilitate the complete exposure of the thyroid lesion area, thereby improving the accuracy of high-intensity focused ultrasound treatment of the thyroid lesion area.

[0044] like Figure 3 and Figure 4As shown, in one embodiment of the present invention, the first support adjustment structure 1 may further include a first support base 13 and a lifting bracket 14. The lifting bracket 14 and the first support base 13 are configured to be raised and lowered relative to each other. The first adjustment component is connected to the first support body 11 through the lifting bracket 14 and is used to adjust the height of the first support body 11 by adjusting the lifting bracket 14 relative to the first support base 13.

[0045] In other words, the first adjustment component is connected to the lifting bracket 14, and the lifting bracket 14 is connected to the first support body 11. In practical applications, the first adjustment component can adjust the lifting bracket 14 relative to the first support base 13, and the first support body 11 can rise and fall with the lifting bracket 14, thereby enabling the first adjustment component to adjust the height of the first support body 11.

[0046] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the number of first support seats 13 can be multiple. The lifting bracket 14 includes a bracket body 141 and multiple lifting connecting parts 142. Multiple first support seats 13 are spaced apart on a first transverse plane parallel to the bracket body 141. The bracket body 141 is connected to the first support body 11 and is configured to cooperate with the multiple first support seats 13 in a relatively lifting manner through the multiple lifting connecting parts 142 corresponding to each other.

[0047] In other words, multiple lifting connecting parts 142 are configured to cooperate with multiple first support seats 13 in a one-to-one manner, allowing them to be raised and lowered relative to each other. The support body 141 is connected to the multiple lifting connecting parts 142, and the first support body 11 is connected to the support body 141. By arranging multiple first support seats 13 at intervals on a first transverse plane parallel to the support body 141, and by configuring the support body 141 to cooperate with the multiple first support seats 13 in a one-to-one manner through the multiple lifting connecting parts 142, the support and lifting stability of the lifting support 14 can be improved.

[0048] like Figure 3 and Figure 4 As shown, optionally, there can be two first support seats 13 and two lifting connection parts 142. The two lifting connection parts 142 are arranged one-to-one at both ends of the bracket body 141 and are arranged to cooperate with the two first support seats 13 in a relatively lifting manner.

[0049] Optionally, the first adjustment component can adjust the lifting of multiple lifting connecting parts 142 relative to multiple first support seats 13 in a one-to-one correspondence. The bracket body 141 can rise and fall with the lifting of multiple lifting connecting parts 142, thereby realizing the adjustment of the lifting bracket 14 relative to the first support seat 13 by the first adjustment component.

[0050] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the first adjustment component may include a first rotating active member, a transmission shaft 121 and a plurality of transmission mechanisms (not shown in the figure). The first rotating active member is connected to the plurality of transmission mechanisms through the transmission shaft 121 and is used to provide rotational power to the plurality of transmission mechanisms through the transmission shaft 121. The plurality of transmission mechanisms are connected one-to-one with a plurality of lifting connection parts 142 and are used to convert the rotational power into lifting power and provide the lifting power to the plurality of lifting connection parts 142 one-to-one.

[0051] In other words, the first rotating drive member is connected to the drive shaft 121, and the drive shaft 121 is connected to multiple transmission mechanisms. In practical applications, the first rotating drive member can provide rotational power to the drive shaft 121 to drive the drive shaft 121 to rotate. The rotation of the drive shaft 121 can transmit the rotational power to multiple transmission mechanisms. The multiple transmission mechanisms can convert the rotational power into lifting power and provide the lifting power to multiple lifting connection parts 142 one by one, thereby causing the multiple lifting connection parts 142 to rise and fall relative to the multiple first support seats 13.

[0052] Optionally, multiple transmission mechanisms can be arranged one-to-one in multiple first support seats 13, and at least a portion of the lifting connection part 142 can be inserted into the corresponding first support seat 13 and connected to the corresponding transmission mechanism.

[0053] In one embodiment of the present invention, the transmission mechanism may include a longitudinal bevel gear, a transverse bevel gear and a lead screw. The longitudinal bevel gear is connected to the transmission shaft 121 and meshes with the transverse bevel gear. The screw of the lead screw is connected to the transverse bevel gear, and the nut of the lead screw is connected to the lifting connection part 142.

[0054] In practical applications, the first rotating active member can provide rotational power to the transmission shaft 121 to drive the transmission shaft 121 to rotate. The rotation of the transmission shaft 121 can drive the longitudinal bevel gear to rotate, the rotation of the longitudinal bevel gear can drive the transverse bevel gear to rotate, the rotation of the transverse bevel gear can drive the screw of the lead screw to rotate, the rotation of the screw of the lead screw can drive the nut of the lead screw to rise and fall relative to the screw of the lead screw, and the rising and falling of the nut of the lead screw relative to the screw of the lead screw can drive the lifting connection part 142 to rise and fall accordingly.

[0055] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the first rotating active member may include a first rotating handle 122 or a first rotating motor 123.

[0056] In practical applications, when the first rotating active component includes the first rotating handle 122, the first rotating handle 122 can be manually rotated to provide rotational power to the transmission shaft 121. When the first rotating active component includes the first rotating motor 123, the first rotating motor 123 can be powered to provide rotational power to the transmission shaft 121.

[0057] Optionally, when the first rotating active component includes a first rotating motor 123, the medical auxiliary device 100 may also include a first drive module and a first button 124. The first button 124 is electrically connected to the first rotating motor 123 through the first drive module. In practical applications, a start electrical signal can be applied to the first drive module via the first button 124, and the first drive module can apply a rotational electrical signal to the first rotating motor 123 based on the start electrical signal to drive the first rotating motor 123 to rotate.

[0058] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the orthographic projection of the support body 141 on the first transverse plane can be arc-shaped, and the arc apex of the support body 141 is connected to the first support body 11.

[0059] In practical applications, when the first support adjustment structure 1 is placed on the treatment bed 200, the arc top of the support body 141 can be placed above the first treatment port 201 of the treatment bed 200. This allows the first support body 11 to be located above the first treatment port 201 of the treatment bed 200, which helps to suspend the patient's neck above the first treatment port 201 and the treatment head, thereby helping to expose the thyroid lesion area to the treatment range of the treatment head.

[0060] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the first support body 11 may include a support body portion 111 and a plurality of support connecting portions 112. The support body portion 111 is arc-shaped and is used to support the head by abutting against the chin. The plurality of support connecting portions 112 are spaced apart on a first longitudinal plane parallel to the support body portion 111. The support body portion 111 is connected to the lifting bracket 14 through the plurality of support connecting portions 112.

[0061] In other words, the main support body is connected to multiple support connecting parts 112, and the multiple support connecting parts 112 are connected to the lifting bracket 14. By making the main support body 111 arc-shaped, it can be adapted to the curved chin of the patient 300, allowing the main support body 111 to support the head by abutting against the chin, and providing a certain degree of envelopment for the head, thereby improving the support stability of the main support body 111. By arranging multiple support connecting parts 112 at intervals on a first longitudinal plane parallel to the main support body 111, and connecting the main support body 111 to the lifting bracket 14 through the multiple support connecting parts 112, the support stability of the main support body 111 can be improved, reducing the possibility and amplitude of head shaking, thereby improving the accuracy of high-intensity focused ultrasound treatment of thyroid lesions.

[0062] like Figure 3 and Figure 4 As shown, optionally, there can be two support connection parts 112, and the two support connection parts 112 are arranged at both ends of the support body part 111 in a one-to-one correspondence.

[0063] Optionally, the lifting bracket 14 may be provided with multiple support insertion slots, and multiple support connection parts 112 are connected to the lifting bracket 14 by being inserted into the multiple support insertion slots in a one-to-one correspondence.

[0064] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the first support adjustment structure 1 may further include a support airbag 15, the support airbag 15 being correspondingly arranged with the first support body 11, the first support body 11 being used to abut against the chin, the support airbag 15 being used to abut against the forehead, and the support airbag 15 and the first support body 11 jointly supporting the head.

[0065] In practical applications, when patient 300 lies prone on treatment bed 200, patient 300's chin can rest against the first support body 11, and forehead can rest against the support airbag 15. Thus, the support airbag 15 and the first support body 11 jointly support the head, improving head support stability. Furthermore, the relatively soft support airbag 15 resting against the forehead enhances head support comfort.

[0066] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the first support adjustment structure 1 may further include an inflation component 16, which is connected to the support airbag 15 and is used to inflate the support airbag 15.

[0067] In practical applications, by inflating the support airbag 15 with the help of the inflation component 16, the size of the inflation of the support airbag 15 can be adjusted according to the actual size of the patient's head 300, so that the support airbag 15 can be against the forehead of the patient 300 with different head sizes, thereby improving the applicability of the medical auxiliary device 100.

[0068] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the first support adjustment component may further include a hanging bracket 17. The hanging bracket 17 is disposed above the first support body 11 and connected to the first adjustment component so that it can change with the change of the height of the first support body 11. The hanging bracket 17 is used to hang the water-sealing garment.

[0069] In practical applications, the water-sealing suit has connecting straps on both sides of the portion of the suit located between the chin and the first support body 11. These two straps can be connected and suspended on the hanging bracket 17. By connecting the two straps, the portion of the water-sealing suit located between the chin and the first support body 11 can wrap around the head. By suspending the two straps on the hanging bracket 17, the portion of the water-sealing suit located between the chin and the first support body 11 can be secured using the hanging bracket 17. Optionally, the two straps can be connected using Velcro.

[0070] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the first support adjustment structure 1 may further include a hanging strap 18, which is connected to the first support body 11 and can be hung on the hanging bracket 17.

[0071] In practical applications, by suspending the sling 18 on the sling bracket 17, the first support body 11 can be fixed with the help of the sling bracket 17, thereby fixing the patient's head and improving the head support stability.

[0072] like Figure 3 and Figure 4 As shown, optionally, each support connection 112 can be provided with a hanging strap 18, and the hanging straps 18 of multiple support connections 112 can be connected to each other and hung on the hanging bracket 17.

[0073] Optionally, multiple hanging straps 18 can be connected by Velcro.

[0074] like Figure 3 and Figure 4 As shown, optionally, the hanging bracket 17 may have a bend 171 for hanging the waterproof clothing and / or the hanging strap 18.

[0075] By suspending the water-sealing garment and / or the hanging strap 18 at the bend 171, the hanging stability of the water-sealing garment and / or the hanging strap 18 can be improved.

[0076] In one embodiment of the present invention, the hanging bracket 17 is adjustable in height relative to the first support body 11.

[0077] In practical applications, if the patient 300 has a large head, the hanging bracket 17 can be raised relative to the first support body 11, increasing the space between the hanging bracket 17 and the first support body 11, so that the head of the patient 300 with a large head can be placed smoothly on the first support body 11, thereby improving the applicability of the medical auxiliary device 100.

[0078] Optionally, the hanging bracket 17 can be threaded into the bracket body 141. In practical applications, the hanging bracket 17 can be raised or lowered relative to the first support body 11 by rotating it.

[0079] like Figure 5 and Figure 6 As shown, in one embodiment of the present invention, the second support body may include a support belt 21, the second support adjustment structure 2 may include a fixed support assembly, the second adjustment assembly 22 may include a second rotating active member and a driven shaft 221, one end of the support belt 21 is connected to the fixed support assembly, and the other end is connected to the driven shaft 221, the driven shaft 221 is rotatably connected to the fixed support assembly, the second rotating active member is connected to the driven shaft 221 and is used to provide rotational power to the driven shaft 221, the support belt 21 is tightened or loosened by winding or unwinding the support belt 21 by the driven shaft 221, so as to adjust the height of the support belt 21.

[0080] In practical applications, the second rotating driving member can provide rotational power to the driven shaft 221 to drive the driven shaft 221 to rotate. The rotation of the driven shaft 221 can cause the end of the support belt 21 connected to the driven shaft 221 to rotate with the driven shaft 221, so that the end of the support belt 21 connected to the driven shaft 221 is wrapped around the driven shaft 221. Since the other end of the support belt 21 is connected to the fixed support assembly, the support belt 21 can be straightened and tightened, so that the height of the shoulder supported by the support belt 21 increases. Alternatively, the rotation of the driven shaft 221 can cause the end of the support belt 21 connected to the driven shaft 221 to rotate with the driven shaft 221, so that the wrapping of the end of the support belt 21 connected to the driven shaft 221 can be canceled, thereby loosening the support belt 21 and lowering the height of the shoulder supported by the support belt 21, thereby realizing the adjustment of the height of the support belt 21.

[0081] Optionally, the support strip 21 can be a gel strip.

[0082] like Figure 5 and Figure 6 As shown, in one embodiment of the present invention, one end of the support belt 21 connected to the driven shaft 221 can be sleeved on the driven shaft 221 and fixedly connected to the driven shaft 221. Alternatively, the second adjustment component 22 may further include a fixing clamp 222, which is fixedly connected to the driven shaft 221, and the end of the support belt 21 connected to the driven shaft 221 is disposed between the driven shaft 221 and the fixing clamp 222.

[0083] By fitting the end of the support belt 21 connected to the driven shaft 221 onto the driven shaft 221 and fixing it to the driven shaft 221, relative rotation between the end of the support belt 21 connected to the driven shaft 221 and the driven shaft 221 can be avoided during the rotation of the driven shaft 221. This allows the driven shaft 221 to stably wind or unwind the support belt 21 during the rotation of the driven shaft 221. By positioning the end of the support belt 21 connected to the driven shaft 221 between the driven shaft 221 and the fixed clamp 222, the fixed clamp 222 and the driven shaft 221 can clamp and fix the end of the support belt 21 connected to the driven shaft 221 between the fixed clamp 222 and the driven shaft 221. This prevents the end of the support belt 21 connected to the driven shaft 221 from rotating relative to the driven shaft 221 during the rotation of the driven shaft 221. Consequently, the driven shaft 221 can stably wind or unwind the support belt 21 during the rotation of the driven shaft 221.

[0084] Optionally, a fixed plane can be provided on the peripheral wall of the driven shaft 221. The fixed plane can extend axially on the driven shaft 221. The fixed plane can be provided with multiple threaded holes. The fixed clamping plate 222 can be provided with multiple through holes, and the multiple through holes correspond one-to-one with the multiple threaded holes.

[0085] By providing a fixed plane on the peripheral wall of the driven shaft 221, it is convenient to place one end of the support belt 21 and to facilitate its cooperation with the fixed clamp 222. In practical applications, one end of the support belt 21 can be placed on the fixed plane first, and then the fixed clamp 222 can be placed on the portion of the support belt 21 located on the fixed plane. At this time, one end of the support belt 21 is located between the fixed plane and the fixed clamp 222. Then, multiple bolts can be passed through multiple through holes one by one and threaded into multiple threaded holes one by one, thereby clamping and fixing one end of the support belt 21 between the fixed clamp 222 and the driven shaft 221 through the fixed clamp 222 and the driven shaft 221.

[0086] like Figure 5 and Figure 6As shown, in one embodiment of the present invention, the second adjustment component 22 may further include a rotation limiting member 223, which is connected to the driven shaft 221 and is used to limit the driven shaft 221 from rotating in the opposite direction to the rotational force.

[0087] This design can prevent the support belt 21 from being wrapped around the driven shaft 221 and tightened during the rotation of the driven shaft 221, or from being unwrapped and loosened by the driven shaft 221 itself after the height of the support belt 21 is adjusted to the appropriate position, thereby improving the support stability of the support belt 21.

[0088] Optionally, the limiting rotation element 223 may include a ratchet.

[0089] Optionally, the limiting rotation member 223 and the second rotation driving member can be arranged at both ends of the driven shaft 221 in a one-to-one correspondence.

[0090] like Figure 5 and Figure 6 As shown, in one embodiment of the present invention, the second rotational active member may include a second rotational handle 224 or a second rotational motor 225.

[0091] In practical applications, when the second rotating drive element includes the second rotating handle 224, the second rotating handle 224 can be manually rotated to provide rotational power to the driven shaft 221. When the second rotating drive element includes the second rotating motor 225, the second rotating motor 225 can be powered to provide rotational power to the transmission shaft 121.

[0092] Optionally, when the second rotating actuator includes a second rotary motor 225, the medical auxiliary device 100 may also include a second drive module and a second button 226. The second button 226 is electrically connected to the second rotary motor 225 through the second drive module. In practical applications, a start electrical signal can be applied to the second drive module via the second button 226. The second drive module can then apply a rotational electrical signal to the second rotary motor 225 based on the start electrical signal, thereby driving the second rotary motor 225 to rotate.

[0093] like Figure 5 and Figure 6 As shown, in one embodiment of the present invention, the fixed support assembly may include a second support base 231, a first fixing frame 232 and a second fixing frame 233. The first fixing frame 232 and the second fixing frame 233 are spaced apart on the second support base 231. The first fixing frame 232 is connected to one end of the support belt 21, and the second fixing frame 233 is provided with a driven shaft 221.

[0094] like Figure 5 and Figure 6 As shown, in one embodiment of the present invention, the second support base 231 has a recess 2311 in its orthogonal projection on a second transverse plane parallel to the second support base 231, and at least a portion of the orthogonal projection of the support band 21 on the second transverse plane is located within the recess 2311.

[0095] This design is due to the fact that in the relevant medical assistive device 100, even if the assistive pad is placed above the patient's chest, the part of the assistive pad above the patient's chest will sink into the first treatment port 201 of the treatment bed 200, and thus cannot support the part above the patient's chest. As a result, in the relevant medical assistive device 100, the assistive pad can only effectively support the part between the patient's waist and chest. The effective support of the assistive pad for the patient's torso is far from the patient's shoulders, and cannot provide sufficient support for the patient's shoulders. The support for the shoulders still needs to rely on the support strap to support the chin, resulting in poor comfort for the patient. Furthermore, the adjustment effect of the assistive pad in raising the shoulder height is poor. In practical applications, the medical auxiliary device 100 provided in this embodiment of the invention allows the second support adjustment structure 2 to be placed on the treatment bed 200. The recess 2311 of the second support seat 231 can be aligned with the first treatment opening 201 of the treatment bed 200. By positioning at least a portion of the orthographic projection of the support strap 21 onto the second transverse plane within the recess 2311, the support strap 21 can be positioned above the first treatment opening 201 of the treatment bed 200. This allows the support strap 21 to support the patient 300 at a position between the chest and shoulder. Compared to auxiliary pads in related technologies, the support strap 21 can support the patient 300 at a position closer to the shoulder than the chest, effectively improving support for the patient 300's shoulder and thus enhancing the patient's comfort. Furthermore, this also improves the shoulder height adjustment effect of the support strap 21, facilitating complete exposure of the thyroid lesion area.

[0096] In summary, the medical auxiliary device 100 provided in this embodiment of the invention enables convenient adjustment of shoulder and / or head height, which is beneficial for complete exposure of the thyroid lesion area, thereby improving the accuracy of high-intensity focused ultrasound treatment of the thyroid lesion area.

[0097] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
