Obviously, the embodiments described below are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0051] It should be noted that the focal point of the medical probe 5 is located at a preset position in the axial direction, so when the medical probe 5 is arranged to be inclined to the Y-axis direction, the axis of the medical probe 5 and the axis of the Y-axis adjusting module 4 must have an intersection point (it is necessary to ensure that they are located on the same plane); at this time, the medical probe 5 is adjusted so that the above intersection point is located in the focusing area of the medical probe 5, so that the acting position of the focusing area can be conveniently adjusted.

[0052] The working principle of the present application is as follows: in operation, the medical probe 5 is installed in the mounting hole 11 on the connecting assembly 1, so that the medical probe 5 is coaxially arranged with the mounting hole 11, so that the axis of the medical probe 5 is arranged to be inclined to the Y-axis direction, the position of the Y-axis adjusting module 4 is first adjusted to a preset reference line; the first adjusting part 32 is operated to drive the first sliding connecting part 31 to move along the X-axis direction, so as to drive the working head to move along the X-axis direction relative to the Y-axis adjusting module 4, so as to adjust the position of the focusing area of the medical probe 5 to a recognizable position, and then the second adjusting part 41 is operated to drive the X-axis adjusting module 3 to move along the Y-axis direction, so that the focusing area of the medical probe 5 moves along the preset reference line to the working area, and the position adjustment of the medical probe 5 is completed; compared with the medical equipment in the prior art, the present positioning device can adjust the position of the focusing area of the medical probe 5 in multiple directions, and drive the focusing area to move along a recognizable trajectory, so as to facilitate the control of the acting position of the medical probe 5, and the overall controllability is high, the position accuracy is high, and the treatment effect can be fully guaranteed.

[0053] It should be noted that the adjustment mode of the medical probe 5 in the present application is not limited to the above mode, but also can be, the first adjusting part 32 and the second adjusting part 41 are respectively operated to drive the support assembly 2 to adjust the position along the X-axis direction and the Y-axis direction respectively, so as to drive the medical probe 5 to have an inclined movement trajectory, and adjust the spatial position, so as to achieve a dynamic adjustment process, which is simple to operate, but the accuracy is relatively general.

Preferably, the first adjusting part 32 is an adjusting screw.

[0055] In combination Figures 1 to 3 As shown in the figure, the adjusting and driving structures of the X-axis adjusting module 3 and the Y-axis adjusting module 4 in the scheme are the same, the Y-axis adjusting module 4 comprises a second connecting rod connected with a second adjusting part 41, and the second connecting rod; both adopt adjusting screws to drive the rotation of the lead screw 13 to achieve the effect of linear driving.

[0056] The specific working principle of the X-axis adjusting module 3 is that the first adjusting part 32 is twisted to drive the rotation of the first connecting rod 34, so that the first sliding connecting part 31 moves linearly along the length direction of the first connecting rod 34 through the action of the threaded part and the first sliding connecting part 31, thereby playing a role of adjusting the position of the support assembly 2.

[0057] Further, the outer side wall of the first housing 33 is provided with a scale part 35 along the length direction thereof; the first sliding connecting part 31 is provided with an extension part 36, the extension part 36 is slidably connected with the outer side wall of the first housing 33; and the extension part 36 is provided with an indicating part for indicating the corresponding scale. Through the cooperation of the indicating part and the scale part 35, the visualization of the displacement distance of the medical probe along the X-axis direction is realized; similarly, the outer side wall of the Y-axis adjusting module 4 is provided with a scale part 35, and the displacement distance of the medical probe along the Y-axis direction can be recognized through the scale part 35.

[0059] In combination Figure 4 As shown in the figure, the support assembly 2 in the scheme is assisted and guided by the guide assembly 24, one side wall of the guide assembly 24 is slidably connected with the Y-axis adjusting module 4, so that the support has good parallelism along the Y-axis.

[0060] Further, the upper end surface of the second supporting arm 23 is provided with a T-shaped groove 25, the T-shaped groove 25 is provided with a T-shaped plate 26, the T-shaped plate 26 is connected with the guide assembly 24; the second supporting arm 23 is provided with a connecting hole penetratingly connected with the T-shaped groove 25, the connecting hole is provided with a connecting bolt 27, one end of the connecting bolt 27 is screwed with the T-shaped plate 26, so that the guide assembly 24 and the second supporting arm 23 are detachably connected.

[0061] It should be noted that in the present scheme, a detachable connecting structure is arranged between the second supporting arm 23 and the guide assembly 24, so that the support assembly 2 can be disassembled, and the shape and size of the support assembly 2 can be replaced to adapt to different working requirements.

[0062] In the present embodiment, one end of the second supporting arm 23 is provided with a connecting boss 28, the connecting boss 28 is inclinedly arranged along the Y-axis direction; the upper end surface of the connecting boss 28 is provided with a mounting groove 29, the mounting groove 29 is rotatably connected with a third adjusting member 12, the third adjusting member 12 is rotatably connected with the connecting boss 28 through a rotating connecting rod 13; by rotating the third adjusting member 12, the connecting assembly 2 can be adjusted around the Y-axis adjusting module. At the same time, since the axis of the mounting hole 11, the axis of the inclined mounting surface 21 and the axis of the Y-axis adjusting module 4 intersect at the same intersection point, the connecting assembly 2 does not damage the position accuracy of the medical probe 5 during rotation.

[0063] In combination with Figure 5 As shown in the figure, in order to facilitate the adjustment of the medical probe 5, a third adjusting member 12 is arranged on the support assembly 2 in the present scheme, the third adjusting member 12 is driven to adjust along the preset inclined direction, the stroke is small, the function of fine adjustment is realized, and the medical probe 5 has more flexible adjustability.

[0064] In the present embodiment, the positioning device further comprises an ultrasonic probe 6 arranged at the lower end of the Y-axis adjusting module 4, for ultrasonic imaging of the user's preset body position. Through the ultrasonic probe 6, the user's target body position for treatment can be identified in advance, so as to facilitate the subsequent positioning work of the medical probe 5.

[0065] In the embodiment, the positioning device further comprises a limiting assembly 7 for positioning the medical probe 5, the limiting assembly 7 comprises an inner ring 71 and an outer ring 72 connected in rotation, the inner ring 71 is connected with the connecting assembly 1 along the same axis; a plurality of abutting pieces 73 are sequentially hinged on the inner side wall of the outer ring 72, the other end of the abutting piece 73 is connected with an elastic piece 74, the elastic piece 74 is used for pushing the abutting piece 73 to move away from the outer ring 72; wherein, the outer side wall of the inner ring 71 is provided with a slope push block 75 opposite to the abutting piece 73; when the outer ring 72 is rotated, the slope push block 75 pushes the abutting piece 73 to rotate, so as to compress the elastic piece 74. Figure 7 and Figure 8 As shown in FIGS. 1-4, the arrow direction in the figure is the opening rotation direction of the limiting assembly 7.

[0066] It should be noted that in the conventional technology, the positioning mode of the medical probe 5 adopts the mode of tightening the steel hoop by the bolt to lock the medical probe 5, but the disadvantage of this mode is that due to the characteristics of the steel hoop, the coaxiality is poor, so the axial precision of the medical probe 5 is poor, which leads to a large deviation when moving.

[0067] Therefore, in the present scheme, the limiting assembly 7 is used to position the medical probe 5, and the specific working principle is that the outer ring 72 is driven to rotate relative to the inner ring 71, the slope push block 75 pushes the abutting piece 73 to rotate, so as to compress the elastic piece 74, so that one end of the abutting piece 73 rotates towards the outer ring 72, and the limiting assembly 7 presents an open state; then one end of the medical probe 5 passes through the inner ring 71, the outer ring 72 is reversely rotated, the abutting piece 73 is reset under the action of the elastic piece 74, and moves away from the outer ring 72, so that the limiting assembly 7 presents a closed state, thereby limiting the medical probe 5.
