Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an ultrasonic therapeutic apparatus. Background Art

[0002] Ultrasound is a high-frequency mechanical wave with focusability, tissue penetration and energy deposition. An ultrasonic therapeutic device is an instrument that uses a focused ultrasonic transducer to focus ultrasound on a biological body, and produces thermal effects, cavitation effects and mechanical effects through the interaction between ultrasound and biological tissues to exert corresponding biological effects. It includes an ultrasonic therapeutic handle and a treatment head. The treatment head is detachably connected to the handle, and the transducer in the treatment head can emit ultrasound to act on the skin.

[0003] The utility model patent with application number CN201520088495.8 discloses a focused ultrasonic beauty device, which is equipped with a rotating motor. Under the control of the rotating motor and the moving motor, the precise distribution of the focused energy points of the focused piezoelectric ceramic sheet on the skin action surface can be precisely controlled. Through a single operation, multiple evenly arranged high-temperature points arranged in a surface can be emitted, and the lateral and longitudinal action positions between points can be precisely controlled.

[0004] However, in industrial production, a speed reducer is required between the output shaft of the rotating motor and the connecting rod of the treatment head. Through the gear transmission within the speed reducer, the high-speed rotational power of the rotating motor is converted into low-speed, high-torque output for the connecting rod. Due to the return clearance (also known as gear backlash) in the speed reducer, when the rotation direction is switched, the return clearance will occupy the number of steps of the rotating motor, resulting in reduced transmission efficiency and deviation in the rotation angle. Ultimately, it is impossible to effectively control the spacing between rows of high-temperature spots. Therefore, to solve the problem of return clearance, the control software usually adds a reverse step equal to the return clearance when switching the direction to compensate for the return clearance.

[0005] Theoretically, after software compensation, the step size of the rotating motor can be transmitted to the transducer completely and without loss. To facilitate assembly of the treatment head, the rotating rod is usually in the middle position. Because an insulating soft seal is installed at the connection between the upper end of the rotating rod and the inside of the treatment head shell, whether the rotating rod rotates left or right, it will be subject to the reset force caused by the elastic deformation of the seal. It may also be subject to the tension of the transducer connection harness (the harness tension is very small and can be ignored). In particular, the reset force of the seal will reverse left and right at the middle position during rotation. The seals on both sides of the rotating rod will also cause unstable force when they are compressed and stretched to different degrees. Therefore, the force of the seal during rotation will cause the rotating rod to deflect, making the software compensation results ineffective. The problem of not being able to effectively control the spacing between the rows of high-temperature points will still exist. There is even a risk that the spacing between two rows of high-temperature points is too close, resulting in excessive energy concentration and burns to the skin. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide an ultrasonic therapeutic device that can transmit the step amount of the rotary motion component to the transducer without loss, ensure that the software compensation is effective in eliminating the return gap, and effectively control the spacing between multiple rows of high-temperature points.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The ultrasonic therapeutic apparatus disclosed in the present invention is provided with a pulling member, and the pulling force of the pulling member on the rotating frame is set to be smaller than the rotational driving force of the rotary motion component on the rotating frame, and greater than the reset force of the sealing component on the rotating frame, so as to pull the rotating frame to one side and deflect the rotating frame by a certain angle. The deflection angle is the rotatable angle corresponding to the return gap in the rotary motion component. Since the pulling force of the pulling member is always in the same direction, the pulling force of the pulling member can offset the reverse reset force generated by the elastic deformation of the seal during rotation, so that the step amount of the rotary motion component can be transmitted to the transducer without loss, ensuring that the result of software compensation to eliminate the return gap is effective, so that the spacing between multiple rows of high-temperature points can be effectively controlled, and the risk of excessive energy concentration and skin burns due to the close spacing between two rows of high-temperature points is avoided.

[0029] 2.

DETAILED DESCRIPTION

[0046] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] As shown in the present invention, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not specifically refer to the singular, but also include the plural. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0048] like Figures 1 to 14 As shown, the ultrasonic therapeutic apparatus of this embodiment includes a handle and a therapeutic head; the handle includes a first shell 10, and the therapeutic head includes a second shell 20;

[0049] The first housing 10 is provided with a linear motion component 11 and a rotary motion component 12;

[0050] The second housing 20 is provided with a connecting rod 21, one end of the connecting rod 21 is connected to the rotary motion assembly 12, the other end of the connecting rod 21 is provided with a rotating frame 22, and the lower end of the rotating frame 22 is provided with a transducer 29;

[0051] Seals 23 are provided on both corresponding sides of the rotating frame 22;

[0052] A pulling member 24 is provided between the second housing 20 and the rotating frame 22. The pulling member 24 is used to pull the rotating frame 22 to one side so that the rotating frame 22 deflects a certain angle.

[0053] The pulling force of the pulling member 24 on the rotating frame 22 is greater than the restoring force of the sealing member 23 on the rotating frame 22, and is less than the rotational driving force of the rotating motion component 12 on the rotating frame 22; wherein, the rotational driving force of the rotating motion component 12 on the rotating frame 22 is greater than the sum of the restoring force of the sealing member 23 on the rotating frame 22 and the pulling force of the pulling member 24 on the rotating frame 22.

[0054] The ultrasonic therapeutic device drives the rotary motion component 12 to move linearly through the linear motion component 11 to achieve single-row dotting treatment; and drives the connecting rod 21 to rotate through the rotary motion component 12, and then cooperates with the linear motion to achieve multi-row dotting treatment. Figure 9 、 Figure 10 、 Figure 13 and Figure 14 As shown, by setting the pulling member 24, and setting the pulling force of the pulling member 24 on the rotating frame 22 to be smaller than the rotational driving force of the rotary motion component 12 on the rotating frame 22, and larger than the restoring force of the sealing member 23 on the rotating frame 22, the rotating frame 22 is pulled to one side, so that the rotating frame 22 is deflected by a certain angle. The deflection angle is the rotatable angle corresponding to the return gap in the rotary motion component 12. Taking the left and right directions in the figure as an example, since the pulling force of the pulling member 24 is always in the same direction, the rotating frame 22 is usually driven to rotate from the right to the left to scan once to complete the treatment of one area, and when switching to the next area, the rotating frame 22 is rotated to the left to scan once. When treating an area, the rotating frame 22 is driven to reverse from the left to the right for reset, and then it can be rotated to the left to scan again to complete the treatment of the next area; therefore, in the process of rotating scanning from right to left, the pulling force of the pulling member 24 can offset the reverse reset force generated by the elastic deformation of the sealing member 23, so that the step amount of the rotary motion component 12 can be transmitted to the transducer 29 without loss, ensuring that the software compensation is effective in eliminating the return gap, so that the spacing between multiple rows of high-temperature points can be effectively controlled, and the risk of excessive energy concentration and skin burns due to the close spacing between two rows of high-temperature points is avoided.

[0055] In this embodiment, the sealing member 23 is preferably a bellows, which has high strength and good durability.

[0056] In this embodiment, the rotating frame 22 is provided with a first hanging portion 231, and the second housing 20 is provided with a second hanging portion 232. The ends of the pulling member 24 are respectively connected to the first hanging portion 231 and the second hanging portion 232. Specifically, the pulling member 24 is disposed between the first hanging portion 231 and the second hanging portion 232, which facilitates installation and facilitates applying a pulling force to the rotating frame 22.

[0057] In this embodiment, the pulling member 24 is preferably a tension spring, the first hanging portion 231 and the second hanging portion 232 are both hooks, and the pulling member 24, the first hanging portion 231 and the second hanging portion 232 are all located on the same side of the rotating frame 22. Specifically, Figure 9 and Figure 10 As shown, the tension spring and the pull hook are both on the right side. By selecting a tension spring with appropriate tension, the two ends of the tension spring are hung on the corresponding hooks, thereby applying tension to the rotating frame 22. This structure is simple and easy to produce and assemble. In other embodiments, the pulling member 24 can also be made of elastic products such as rubber ropes and rubber rings.

[0058] In this embodiment, the second housing 20 is provided with a slide groove 233 for the second hooking portion 232 to move back and forth, thereby enabling the second hooking portion 232 to move forward and backward along with the rotating frame 22. Specifically, when the rotating frame 22 moves linearly, the cooperation between the second hooking portion 232 and the slide groove 233 allows the second hooking portion 232 to move linearly along with the rotating frame 22, thereby improving the stability of the structure.

[0059] In this embodiment, a sealed chamber is defined within the second housing 20, and the second attachment portion 232 is positioned at the top of the sealed chamber. Specifically, components such as the rotating frame 22, the seal 23, and the transducer 29 are all positioned within the sealed chamber, which is also filled with a liquid capable of conducting ultrasound waves. A treatment window is positioned at the lower end of the sealed chamber, where a sealing diaphragm is located. The second attachment portion 232 is positioned on the top wall of the sealed chamber, which is a flat surface for ease of processing and installation. In other embodiments, the second attachment portion 232 may also be positioned on the side wall of the sealed chamber.

[0060] In this embodiment, a first mounting seat 201 and a second mounting seat 202 are provided on the second shell 20, and the connecting rod 21 passes through the first mounting seat 201 and extends into the second shell 20. A guide rod 25 is provided between the first mounting seat 201 and the second mounting seat 202, and the connecting rod 21 can slide along the guide rod 25; one end of the connecting rod 21 located in the second shell 20 is the mounting end 211, and the upper end of the rotating frame 22 is connected to the mounting end 211, one of the sealing members 23 is provided between the first mounting seat 201 and one side of the mounting end 211, and the other sealing member 23 is provided between the second mounting seat 202 and the other side of the mounting end 211; a gas channel for connecting the two sealing members 23 is provided on the connecting rod 21. Specifically, when the connecting rod 21 drives the rotating frame 22 to move linearly and rotationally, the connecting rod 21 can slide along the guide rod 25. The guide rod 25 guides the connecting rod 21, which can avoid shaking of the mounting end 211 of the connecting rod 21, making the movement of the rotating frame 22 more stable, thereby ensuring the stable movement of the transducer 29 and ensuring the treatment effect; the setting of the two seals 23 can prevent liquid leakage and electric leakage; through the setting of the gas channel, when the rotating frame 22 moves linearly, the gas in the seals 23 on both sides can flow to each other, thereby balancing the air pressure in the seal 23, avoiding the air pressure in the seal 23 from generating resistance to the linear motion, which is beneficial to the linear motion and improves the reliability of the structure.

[0061] In this embodiment, the first mounting seat 201 is provided with a mounting portion 203 for mounting the guide rod 25, thereby locating the guide rod 25. The connecting rod 21 is provided with a clearance groove 212 for avoiding the mounting portion 203, thereby facilitating the reciprocating movement of the connecting rod 21. Specifically, the mounting portion 203 serves as a mounting support for the guide rod 25. The clearance groove 212 avoids the mounting portion 203, thereby facilitating the reciprocating movement of the connecting rod 21. The mounting portion 203 is provided with a protruding mounting post, and the guide rod 25 is a hollow rod that is sleeved on the mounting post to facilitate installation and positioning. In other embodiments, the mounting portion 203 may also be provided with a mounting hole, and the guide rod 25 can be inserted into the mounting hole for positioning.

[0062] In this embodiment, an opening is provided at the end of the mounting end 211, and a vent sleeve 26 is provided between the mounting end 211 and the guide rod 25. The vent sleeve 26 is provided with a vent groove 261. The opening, the vent groove 261 and the avoidance groove 212 form a gas channel. Specifically, Figure 7 As shown, taking the right seal 23 being compressed as an example, the gas in the right seal 23 flows from the opening through the vent groove 261 and the avoidance groove 212 into the left seal 23 to balance the air pressure in the seals 23 on both sides. This novel structure can not only ensure the sealing effect, but also avoid the air pressure from generating resistance to linear motion, and also avoid the air pressure from repeatedly squeezing the seal 23 and affecting the service life of the seal 23. Figure 12As shown, a plurality of vent grooves 261 are provided, and the plurality of vent grooves 261 are arranged at intervals along the circumference.

Specifically, the screw motor 111 is preferably a double-headed screw motor, which can reduce the space occupied in the first shell 10, and guide and limit the transmission seat 112 through the guide seat 113 and the guide rail 114 to improve the stability of movement; the first connecting head 123 is driven to rotate by the cooperation of the rotating motor 121 and the reducer 122, thereby realizing the rotation of the rotating frame 22. Under the action of the pulling member 24, the step amount of the rotating motor 121 can be transmitted to the transducer 29 without loss, ensuring that the software compensation is effective in eliminating the return gap, so that the spacing between multiple rows of high-temperature points can be effectively controlled, further improving the reliability of the device; by using the plug-in method, the positioning and anti-slipping of the treatment head are realized through the cooperation of the ball head plunger 124 and the plunger hole 281, the transmission reliability is higher, and the stable back and forth movement of the rotating frame 22 can be ensured, and the separation of the treatment head and the handle can be avoided, thereby ensuring the safety of the treatment process and stable power output.

Figure 6 and Figure 7 As shown, when the treatment head is removed, the reset member 27 pushes the mounting end 211 to the rightmost end, so that the second connecting head 28 abuts against the first mounting seat 201, preventing the connecting rod 21 and the rotating frame 22 from moving freely after removal, playing a protective role and facilitating transportation and storage.

[0066] In this embodiment, the reset member 27 is a reset spring, which is sleeved on the outside of the guide rod 25.
