Description

Technical Field

[0001] The invention relates to the field of medical device manufacturing, and in particular to a low-intensity pulsed ultrasound treatment device and a use thereof. Background Art

[0002] Femoral head necrosis is one of the common causes of hip pain and dysfunction. Especially since the invention and widespread use of glucocorticoids, long-term or excessive use of glucocorticoids has become the number one cause of the disease. Compared with patients with other types of femoral head necrosis, patients with steroid-induced femoral head necrosis are generally younger in age, and most are still in the labor force. Younger patients not only have to face the adverse effects of a long course of disease, but also have to consider how to better protect joint function in the early and middle stages of the disease, avoid premature loss of ability to work, and the durability of artificial hip prostheses and the additional risks of multiple revisions.

[0003] It is generally believed that insufficient blood supply to local tissues is the main factor leading to the occurrence and development of femoral head necrosis. Relevant studies have confirmed that appropriate mechanical stimulation can activate mechanical ion channels, effectively promote VEGF (vascular endothelial growth factor) metabolism, promote the production of osteoblasts and H-capillaries, thereby improving the blood supply to the femoral head and enhancing osteogenic differentiation, and has a good therapeutic effect on joint protection in patients with early and middle stage femoral head necrosis.

[0004] Low intensity pulsed ultrasound (LIPUS) is a new type of therapeutic ultrasound characterized by high energy density, strong penetration and high safety. Its energy density is high and precisely adjustable and controllable, with higher treatment accuracy and applicable population, and lower side effects. Compared with traditional high intensity focused ultrasound (HIFU), LIPUS has good mechanical effect and minimal tissue thermal effect; compared with extracorporeal shock-wave therapy (ESWT), LIPUS has low single pulse energy but high repetition frequency, and its emission energy is precisely controllable, with higher treatment safety and wider applicable population.

[0005] Currently, extracorporeal shock wave physical therapy is used for femoral head necrosis and related diseases. This type of equipment is expensive, bulky, and requires professional operation. Patients need to be hospitalized for treatment. Moreover, this treatment is only effective for patients in the middle and late stages, which causes inconvenience to patients with femoral head necrosis in the middle and late stages who have difficulty walking. In addition, the treatment process is very painful, and the shock wave energy is often out of focus due to body movement. These shortcomings lead to poor compliance with this type of treatment and poor clinical results.

[0006] Therefore, there is an urgent need for a physical therapy instrument with potential for home application scenarios and that is safer and more portable, so that patients with femoral head necrosis can receive convenient and effective self-treatment. Studies have shown that low-intensity pulsed ultrasound therapy has shown positive therapeutic effects in promoting VEGF and H-angiogenesis. In addition, low-intensity pulsed ultrasound also has the advantages of small device size, precise and adjustable parameters, and convenient and quick use. On this basis, the present invention proposes a wearable low-intensity pulsed ultrasound treatment device, as well as its use in femoral head necrosis and related diseases. Summary of the invention

[0033] like Figure 1-3 The low-intensity pulsed ultrasound treatment device shown includes Figure 3 The housing 1 shown in the figure has a plurality of pulsed ultrasonic generators 11 connected to the controller 4 arranged side by side in the housing 1, and the pulsed ultrasonic generators 11 are used to generate low-intensity pulsed ultrasonic waves. The frequency of the low-intensity pulsed ultrasonic waves generated by the pulsed ultrasonic generator is greater than 20Khz and less than 20Mhz, and the spatial intensity is greater than 0.1W / cm 2 And less than 3W / cm 2 .

[0034] A pulse transmission channel formed by a water bag 12 is arranged on the pulse output channel of the pulse ultrasonic generator 1. It should be noted that the surface area 121 of the water bag 12 after being filled needs to cover the area 111 of the pulse output channel of the pulse ultrasonic generator 11. This can facilitate the transmission of low-intensity pulsed ultrasound.

[0035] The thickness of the water bag ranges from 0.1 mm to 0.15 mm, which facilitates the smooth transmission of low-intensity pulsed ultrasound.

[0036] The temperature of the water bag 12 is controlled by a heating control device (not shown in the figure) connected to the controller 4.

[0037] The heating control device here can be various commercial flexible heating control devices.

[0038] The controller 4 is provided with a human-machine interaction interface 41, which is used by the user to input shutdown instructions, startup instructions, startup confirmation instructions and parameter adjustment instructions of the ultrasonic treatment device; the parameters at least include the frequency and spatial intensity of low-intensity pulsed ultrasound and the temperature adjustment of the water bag.

[0039] The controller 4 is provided with a display 42 , through which shutdown instructions, startup instructions, startup confirmation instructions and parameter adjustment instructions are displayed and confirmed.

[0040] The outside of the shell 1 is installed by means of the flexible belt 2 and the shell installation surface 301 cut on the flexible fixing member 3 and matching the shape of the shell 1.

[0041] The pulse ultrasonic generator 11 and the water bag 12 in the shell 1 are integrally assembled on the shell mounting surface 301 , and the fixed positions of the upper and lower assemblies are controlled by secondary restraint of the shell 1 and the flexible belt 2 .

[0042] The edge of the flexible fixing member 3 is provided with an adhesive surface, and the flexible fixing member 3 is attached to the treatment part of the user correspondingly to form a flexible treatment restraint cavity through mutual bonding or detachment of different adhesive surfaces.

[0043] Specifically, the flexible fixing member 3 is a first flexible fixing member 31 and a second flexible fixing member 32 attached to each other, and a first protruding end 311 of the first flexible fixing member 31 and a first protruding end 321 of the second flexible fixing member 32 are attached to each other.

[0044] The second protruding end 312 of the first flexible fixing member 31 and the second protruding end 322 of the second flexible fixing member 32 are attached to each other to form a flexible treatment restraint cavity.

[0045] The width of the flexible treatment restraint cavity can be adjusted by adjusting the attachment angle and depth.

[0046] Because of the above structure, the working principle of the present invention is:

[0047] After the machine is turned on, the frequency and spatial intensity of the low-intensity pulsed ultrasound and the temperature of the water bag are adjusted according to the parameters set by the human-machine interaction interface 41 of the controller 4 to meet the needs of different users.

[0048] The width of the flexible treatment restraint cavity is adjusted according to different treatment parts, so that the lower end of the water bag is attached to the treatment part of the therapist and the low-intensity pulse ultrasound is effectively transmitted.

[0049] The present invention combines a pulsed ultrasound generator of low-intensity pulsed ultrasound with a water bag, and fixes them in a flexible fixing part. When in use, the device is wrapped around the patient's hips and hips, so that the water bag is aligned with the patient's treatment part and is close to its surface skin; at this time, the tension generated by the deformation of the flexible fixing part can squeeze the water bag to form an effective restraint, generate an efficient energy transmission channel, and enhance the treatment function. The flexible treatment restraint cavity formed by the flexible fixing part can adapt to different users and different treatment parts, so that the energy transmission channel can better fit the treatment part.

[0050] The basic principles and main features of the invention and the advantages of the invention are shown and described above.
