Technical Field

[0001] The utility model relates to the technical field of medical body surface energy treatment and massage, and in particular to a magnetic spring force compensation device for controlling the movement of an ultrasonic transducer. Background Art

[0002] Ultrasonic uterine rejuvenation technology is a medical technology that uses ultrasonic energy to penetrate the body surface to rehabilitate the female uterus. Its main working principle is to use an ultrasonic transducer to press on the female belly and emit ultrasonic energy into the body. In order to avoid localized fever and burns caused by long-term energy acting on one point, the ultrasonic transducer needs to be moved continuously on the belly. In reality, the body surface of a parturient woman after childbirth is often uneven or has wrinkles such as stretch marks, which hinders the plane movement of the ultrasonic transducer.

[0003] The existing ultrasonic transducer movement technology routes are mainly divided into two categories: the first category is manual or robotic arm bionics, and the second category is automatic operation. Under the first technical route, the ultrasonic transducer can change its height and angle well, fit the belly well in real time, and avoid obstacles such as uneven surface or stretch marks, so as to achieve good treatment effect and experience, but manual treatment requires the operator to bear huge labor intensity, and the robotic arm bionic solution has the disadvantage of high cost; under the second technical route, the main implementation method of automatic operation is rotation or reciprocating motion, and no matter which motion implementation method is used, it is basically based on plane motion, which is difficult to overcome the influence of uneven surface or stretch marks and other wrinkles encountered in the plane motion of the ultrasonic transducer, which can easily lead to problems such as blockage and stagnation of ultrasonic transducer movement, scraping of coupling agent, and excessive local pressure leading to excessive surface temperature during treatment. Utility Model Content

[0004] Technical purpose: In view of the shortcomings of the existing technology, the utility model discloses a magnetic spring force compensation device for controlling the movement of an ultrasonic transducer, which can effectively solve the problem that it is difficult to overcome the obstacles of ups and downs or wrinkles encountered in planar movement under the automatic operation scheme of the ultrasonic transducer in the existing technology, improve the smoothness of movement during use, maintain appropriate pressure and avoid the phenomenon of coupling agent being scraped off.

[0005] Technical solution: To achieve the above technical objectives, the utility model adopts the following technical solution:

[0006] A magnetic spring force compensation device for controlling the movement of an ultrasonic transducer comprises a magnetic core base for mounting the ultrasonic transducer, the magnetic core base is fixedly connected to the lower end of a linear guide rail, the upper end of the linear guide rail is slidably connected to a slider and can move up and down along the slider, the slider is fixed to a magnetic cylinder auxiliary block, the magnetic cylinder auxiliary block is fixed to the lower end of an adapter plate, a fixing component is arranged at the upper end of the adapter plate, the fixing component is fixedly connected to the upper end of a magnetic cylinder, the lower end of the magnetic cylinder passes through the magnetic cylinder auxiliary block, when the ultrasonic transducer is not mounted, the lower end of the magnetic cylinder contacts the magnetic core base, a magnetic core is arranged in the magnetic core base, the lower end of the magnetic core is fixed to the magnetic core base, and the upper end is passed through the magnetic cylinder, the interaction between the magnetic core and the magnetic cylinder generates a magnetic attraction opposite to the gravity direction of the ultrasonic transducer.

[0007] Preferably, the fixing assembly comprises a fixing base, on which a groove corresponding to the shape of the end of the magnetic cylinder is formed, and the magnetic cylinder is clamped in the groove and fixed to the fixing base.

[0008] Preferably, an L-shaped adapter plate for installing the magnetic elastic force compensation device is also fixedly arranged on the fixed base.

[0009] Preferably, a limit block for limiting the linear guide rail from falling out of the sliding block is provided at one end on the same side as the fixed component.

[0010] Preferably, the materials of the magnetic cylinder and the magnetic core are both permanent magnets, and the magnetic cylinder and the magnetic core do not contact each other.

[0011] Beneficial effects: The magnetic spring force compensation device for controlling the movement of an ultrasonic transducer provided by the utility model has the following beneficial effects:

[0012] The magnetic spring force compensation device of the utility model offsets a part of the gravity of the ultrasonic transducer through the strong magnetic force of mutual attraction between the magnetic core and the magnetic cylinder, so that the pressure of the ultrasonic transducer on the contact surface can be reduced. At the same time, because the pressure of the ultrasonic transducer on the contact surface is reduced, the heat generation caused by friction can be reduced, and the squeezing and scraping of the coupling agent applied on the contact surface by the ultrasonic transducer can be greatly reduced, thereby reducing the number of times the coupling agent is added during use.

[0013] The magnetic spring force compensation device of the utility model is provided with a linear guide rail. When the ultrasonic transducer encounters an uneven, undulating, wrinkled contact surface during movement, the ultrasonic transducer and the magnetic core base on which the ultrasonic transducer is mounted can move up and down under the constraint of the linear guide rail, thereby being able to control the ultrasonic transducer to more easily adhere to the contact surface and move up and down, overcoming obstacles and greatly improving the use effect.

[0018] The present invention will be described more clearly and completely below by way of a preferred embodiment in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiment.

[0019] like Figure 1-2 As shown, a magnetic spring force compensation device for controlling the movement of an ultrasonic transducer includes a magnetic core base 6 for mounting the ultrasonic transducer, the magnetic core base 6 is fixedly connected to the lower end of a linear guide rail 5 by screws, the upper end of the linear guide rail 5 is slidably connected to a slider 4, and can move up and down along the slider 4, the side of the slider 4 that is not in contact with the linear guide rail 5 is fixed to the inner side wall of a magnetic cylinder auxiliary block 2 by screws, and the outer wall of the magnetic cylinder auxiliary block 2 away from the slider 4 is fixed to the lower end of an adapter plate 1, and the adapter plate 1 A fixing assembly is provided at the upper end, and the fixing assembly is fixedly connected to the upper end of a magnetic cylinder 3. The fixing assembly includes a fixing base 8, and a card slot corresponding to the shape of the upper end of the magnetic cylinder 3 is opened on the fixing base 8. The upper end of the magnetic cylinder 3 is clamped in the card slot. The magnetic cylinder 3 is fixed to the side of the fixing base 8 by screws. The lower end of the magnetic cylinder 3 passes through the magnetic cylinder auxiliary block 2, and the linear guide 5 is located between the slider 4 and the magnetic cylinder 3. When the ultrasonic transducer is not mounted, the lower end of the magnetic cylinder 3 is in contact with the magnetic core base 2. The material of the magnetic cylinder 3 is a permanent magnet;

[0020] A magnetic core 7 is arranged in the magnetic core base 6. The material of the magnetic core 7 is a permanent magnet. One end of the magnetic core 7 is fixed to the magnetic core base 6, and the other end is passed through the magnetic tube 3. The magnetic core 7 and the magnetic tube 3 do not contact each other. A magnetic force of nearly constant 4N will be generated between the magnetic core 7 and the magnetic tube 3 within a movement stroke of 45mm. The magnetic force exerted on the magnetic core 7 will act on the magnetic core base 6, thereby generating a force opposite to the gravity direction of the ultrasonic transducer, thereby buffering the pressure of the ultrasonic transducer on the contact surface.

[0021] A limit block 9 is also provided at the upper end of the linear guide 5 for limiting the linear guide 5 from escaping from the slider. At the same time, when the device is in a stationary state, the magnetic core base 6 is in contact with the magnetic cylinder, which also limits the upward sliding distance of the linear guide 5.

[0022] An L-shaped adapter plate 10 for mounting the entire magnetic spring force compensation device on a designated device is also fixedly disposed on the fixed base 8 .

[0023] The working principle of the utility model is as follows: first, the entire magnetic spring force compensation device is fixed on the specified equipment through the L-shaped adapter plate 10, and then the ultrasonic transducer is mounted on the magnetic core base 6. The ultrasonic transducer contacts the surface of the position specified by the user. When the ultrasonic transducer moves on the contact surface, it will drive the linear guide 5 to move up and down. During the movement, the magnetic core 7 and the magnetic cylinder 3 will generate a strong magnetic force of mutual attraction close to a constant 4N within a movement stroke of 45mm. The magnetic core 7 and the magnetic cylinder 3 do not contact each other. The strong magnetic force of mutual attraction will reduce the pressure of the ultrasonic transducer on the contact surface, play a buffering role, and can reduce the friction force and thus reduce Due to the heat generated by friction, the squeezing and scraping of the coupling agent applied on the contact surface by the ultrasonic transducer is greatly reduced, and the number of times the coupling agent is added during use is reduced; at the same time, when the contact surface becomes uneven, undulating, or wrinkled during the movement of the ultrasonic transducer, the ultrasonic transducer can move up and down with the help of the linear guide 5 because it is mounted on the magnetic core base 6, so that it can move along the uneven, undulating, or wrinkled contact surface. At the same time, the limit block 9 on the linear guide 5 can limit the movement range of the linear guide 5 to ensure that it will not slide out of the slider 4, thereby ensuring that the ultrasonic transducer moves along the contact surface during use, thereby improving the use effect.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
