[0032] In the related art, for an ultrasonic product such as an ultrasonic therapeutic instrument, the focal plane distance at which the transducer emits energy exceeds the specified upper or lower limit range, resulting in a risk of treatment accidents. Currently, the focal plane distance of ultrasonic products is generally detected and calibrated by punching acrylic plates of different thicknesses on the ultrasonic products during factory production.

[0033] The present utility model provides a treatment head 10.

[0034] Please refer to Figure 1 and Figure 2 , in an embodiment of the present utility model, the treatment head 10 includes:

[0035] A housing 11, the housing 11 having a sound-transmitting end;

[0036] A detection component 13, the detection component 13 being disposed inside the housing 11; and

[0037] A transducer component 12, the transducer component 12 being movably disposed inside the housing 11 and having a moving stroke of moving towards or away from the sound-transmitting end. The transducer component 12 has a calibration position on its moving stroke. During the process of the transducer component 12 moving towards the sound-transmitting end to the calibration position, the transducer component 12 approaches the detection component 13, and the detection component 13 is used to detect whether the transducer component 12 moves in place;

[0038] During the process of the transducer component 12 moving away from the sound-transmitting end from the calibration position, the transducer component 12 can adjust its focusing depth.

[0039] Among them, the housing 11 serves as the installation base for the treatment head 10 and is used to accommodate the detection component 13 and the transducer component 12. The transducer component 12 is used to emit energy towards the sound-transmitting end of the housing. It can be drivingly connected to the driving component 21 so as to move towards or away from the sound-transmitting end of the housing 11 under the drive of the driving component 21, thereby realizing the function of adjusting the movement of the transducer component 12 within the housing 11, and realizing the focusing treatment of the ultrasonic therapeutic apparatus by changing the position of the transducer component 12. Moreover, the treatment head 10 is further provided with a detection component 13. The detection component 13 is arranged within the housing 11 and is used to detect whether the transducer component 12 has moved into place.

[0040] Specifically, when using the ultrasonic therapeutic apparatus 100, the position of the transducer component 12 in the treatment head 10 can be initially calibrated first. When initially calibrating the transducer component 12, first drive the transducer component 12 to move towards the sound-transmitting end of the housing 11 along its moving stroke until the detection component 13 detects that the transducer component 12 has reached the preset calibration position, so as to realize the automatic calibration of the focal plane distance of the transducer component 12.

[0041] Then, drive the transducer component 12 to move away from the sound-transmitting end from the calibration position, so as to adjust the focusing depth of the transducer component 12 to the selected depth by controlling the length of this moving stroke. Among them, the focusing depth refers to the distance from the sound-transmitting port of the transducer component 12 to under the skin.

[0042] In some embodiments, the focusing depth can be set to 2 mm for corresponding to the dermis layer of the skin; the focusing depth can also be set to 3 mm for corresponding to the fat layer of the skin; the focusing depth can also be set to 4.5 mm for corresponding to the SMAS fascia layer of the skin.

[0043] It should be noted that the transducer component 12 of the present utility model can simultaneously have multiple selected depths with different numerical values and can be switched and adjusted between different selected depths.

[0044] Specifically, after adjusting the focusing depth of the transducer component 12 to one of the selected depths, when performing the second adjustment on the transducer component 12, the adjustment steps based on the calibration position in the foregoing embodiments can be repeated, that is, first drive the transducer component 12 to reach the preset calibration position, and then realize the focal length calibration of the transducer component 12 based on the calibration position. Of course, when performing multiple adjustments, the same adjustment steps can be followed and will not be elaborated here.

[0045] Of course, the technical solution of the present utility model is not limited thereto. In some embodiments, the transducer component 12 can also realize the focal length calibration of the transducer component 12 based on its previous selected depth.

[0046] Specifically, after adjusting the transducer assembly 12 to the previously selected depth, the further movement direction and movement stroke of the transducer assembly 12 can be obtained based on the difference between the current selected depth and the previously selected depth. By controlling the length of the movement stroke and the movement direction of the transducer assembly 12, the transducer assembly 12 can move toward or away from the sound-transmitting end of the housing 11 at the previously focused position to decrease or increase the focusing depth of the transducer assembly 12. In this way, the flexibility of the automatic calibration of the transducer assembly 12 can be improved.

[0047] In some embodiments, the detection component 13 can implement the detection function through non-contact detection. For example, the detection component 13 can be set as a photoelectric sensor, a grating encoder, etc.

[0048] Of course, the technical solution of the present invention is not limited to this, and the detection component 13 can also implement the detection function through contact detection.

[0049] In an embodiment of the present invention, the detection component 13 is a pressure sensor. When the transducer assembly 12 is in the calibration position, at least a part of the transducer assembly 12 abuts against the pressure sensor to detect whether the transducer assembly 12 has moved in place.

[0050] Specifically, when the transducer assembly 12 moves to abut against the pressure sensor, it can be determined that the transducer assembly 12 has reached the preset calibration position. It can be understood that, compared with configuring the detection component 13 as a photoelectric sensor, a grating encoder, etc., setting the detection component 13 as a pressure sensor can not only detect quickly, but also help save the internal space of the treatment head 10 and facilitate the assembly of the detection component 13.

[0051] Please refer to Figure 2 , in an embodiment of the present invention, a convex structure 131 is provided on the side of the pressure sensor facing the transducer assembly 12 for abutting against the transducer assembly 12. In this way, the pressure sensor can abut against the transducer assembly 12 through the convex structure 131 as its detection end, so as to facilitate the in-place detection of the transducer assembly 12.

[0052] Please refer to Figure 2 , in an embodiment of the present invention, there are a plurality of the convex structures 131, and the plurality of convex structures 131 are arranged at intervals in sequence along the circumferential direction of the pressure sensor. By providing a plurality of convex structures 131, a plurality of detection ends can be formed on the pressure sensor. The specific number of the convex structures 131 can be set according to actual needs.

[0053] Furthermore, when multiple detection ends all feedback contact signals with the transducer assembly 12 , it can be determined that the transducer assembly 12 is completely in place, thereby improving the detection accuracy of the pressure sensor.

[0054] Of course, the technical solution of the present invention is not limited to this. In addition to the photoelectric sensor, grating encoder, and pressure sensor mentioned in the above embodiments, the detection component 13 can also be configured as an infrared photoelectric switch, a limit switch, etc. The specific implementation method can be configured according to actual needs and is not limited here.

[0055] It should be noted that when the transducer assembly 12 reaches the calibration position, the detection assembly 13 can be located on the side of the transducer assembly 12 facing the sound-transmitting end, or on the side of the transducer assembly 12 away from the transmission end, or on the circumferential side of the transducer assembly 12, or at any other position where detection can be achieved.

[0056] See also Figure 1 and Figure 2 In one feasible embodiment, the detection assembly 13 is disposed on a side of the transducer assembly 12 facing the sound-transmitting end, with at least a portion of the detection assembly 13 disposed opposite a peripheral edge of the transducer assembly 12. The detection assembly 13 can determine whether the transducer assembly 12 has reached the calibration position by detecting the position of the peripheral edge of the transducer assembly 12.

[0057] In some embodiments, the calibration position can be set as the extreme position of the movement of the transducer assembly 12 toward the sound-transmitting end of the housing 11. In this way, the detection assembly 13 is arranged on the side of the transducer assembly 12 facing the sound-transmitting end in the calibration position, which can prevent the detection assembly 13 from interfering with the movement of the transducer assembly 12.

[0058] Specifically, see Figure 2 In an embodiment of the present invention, the detection component 13 is an annular structure with a hollow interior, which is used to enclose and form a sound-permeable hole to avoid the sound wave transmission path of the transducer component 12.

[0059] With such an arrangement, on the one hand, the sound wave transmission path of the transducer assembly 12 can be avoided through the sound-transmitting holes in the annular structure to ensure the normal operation of the transducer assembly 12. On the other hand, by arranging the detection assembly 13 along the circumference of the transducer assembly 12, it is also beneficial to increase the relative area between the detection assembly 13 and the transducer assembly 12, so as to accurately detect the position of the transducer assembly 12.

[0060] In another feasible embodiment, the detection component 13 is located on a side of the transducer component 12 away from the sound-transmitting end, the detection component 13 is provided with a avoidance opening, and the transducer component 12 is movably arranged in the avoidance opening.

[0061] With such a setting, the movement path of the transducer assembly 12 can be avoided through the avoidance opening, preventing interference between the transducer assembly 12 and the detection assembly 13 when the transducer assembly 12 moves towards or away from the sound-transmitting end of the housing 11, thereby ensuring the normal implementation of the focal length adjustment function of the transducer assembly 12.

[0062] Please refer to Figure 1 In the embodiment of the present invention, one end of the transducer assembly 12 facing away from the sound-transmitting end is used to connect to the driving assembly 21, so as to move towards or away from the sound-transmitting end under the drive of the driving assembly 21.

[0063] Among them, the driving assembly 21 can be but is not limited to being set as a linear telescopic motor, a stepping motor and other linear driving mechanisms to directly drive the transducer assembly 12 to linearly move towards or away from the sound-transmitting end of the housing 11 of the treatment head 10.

[0064] In some embodiments, the driving assembly 21 can also include a rotary driving mechanism such as a rotary motor and a transmission mechanism. The transmission mechanism can be but is not limited to being set as a lead screw transmission mechanism, etc. The rotary driving mechanism can drive at least part of the transmission mechanism to rotate, and further convert the rotational motion into a linear motion to drive the transducer assembly 12 to linearly move towards or away from the sound-transmitting end of the housing 11 of the treatment head 10. The specific implementation method can be set according to actual needs and is not limited herein.

[0065] In the embodiment of the present invention, the detection assembly 13 and the driving assembly 21 are electrically connected and are used to feedback the in-place detection result to the driving assembly 21 in real time.

[0066] By accurately and timely feeding back the detection result of the detection assembly 13 to the driving assembly 21, it is beneficial to quickly calibrate the position of the transducer assembly 12.

[0067] The present invention also proposes an ultrasonic therapeutic apparatus 100, which includes a main body 20 and a treatment head 10. The specific structure of the treatment head 10 refers to the above embodiment. Since this ultrasonic therapeutic apparatus 100 adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated herein one by one.

[0068] Among them, the main body 20 and the treatment head 10 are detachably connected. The driving assembly 21 can be built into the housing 11 of the treatment head 10 and be drivingly connected to the transducer assembly 12 in the housing 11; the driving assembly 21 can also be arranged at one end of the main body 20 facing the treatment head 10 and be drivingly connected to the transducer assembly 12 in the housing 11, which is not limited herein.

[0069] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
