Description

Technical Field

[0001] The invention belongs to the technical field of medical machinery, and in particular relates to a low-intensity pulsed ultrasound (LIPUS) fracture interventional treatment table. Background Art

[0002] LIPUS is a "green" and healthy physical therapy program after fracture surgery. Due to the limited activity of fracture patients after surgery, the fracture site lacks sufficient mechanical stimulation, which leads to bone loss. LIPUS provides continuous mechanical stimulation to the fracture site in the form of periodic loads, thereby compensating for the adverse effects of the above-mentioned bone loss and shortening the patient's recovery period. At present, the actual application of ultrasound trolleys is limited to the treatment of superficial soft tissues and diagnosis, while LIPUS has been clinically proven to have good therapeutic effects on deep tissues, but it has not been popularized on a large scale. LIPUS can not only be used to treat fractures, but also has a good mechanical therapeutic effect on soft tissues such as human muscles that lack mechanical stimulation for a long time. However, since the content and distribution of soft tissues in various parts of the body of the target audience are different, the setting of ultrasound parameters should depend on the specific physical condition of the patient.

[0003] Research has found that LIPUS has been used in clinical postoperative skin healing and rehabilitation treatment for patients after fracture surgery. Currently, small ultrasonic therapeutic devices are mainly used at home and abroad to perform rehabilitation treatment for acute postoperative skin healing, but the treatment effect is not obvious for patients with deep tissue trauma, such as femoral fractures.

[0004] At present, LIPUS has certain applications in real life for relieving muscle strain and superficial tissue discomfort at home, but the design of postoperative rehabilitation treatment equipment for deep tissue surgery in hospitals is still lagging behind. LIPUS mainly adjusts the irradiation frequency to achieve the ability to penetrate a certain tissue. At that time, adjusting the ultrasound duty cycle (the ratio of the working time to the rest time within the unit working time of the ultrasound) can control the ultrasound action time within the unit irradiation cycle. For tissues with little force, the LIPUS sound intensity can be adjusted to increase the tissue force and provide sufficient mechanical stimulation.

[0005] At present, the existing ultrasound radiation carts in domestic hospitals are mainly used for treatment, and the only LIPUS treatment carts are only sufficient for postoperative skin healing and superficial soft tissue treatment of patients. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the current low-intensity pulsed ultrasound (LIPUS) deep tissue treatment equipment, and provide a LIPUS fracture interventional treatment table, which is set according to the height of the human body. A telescopic ultrasonic trolley can be adjusted according to the specific height of the patient and the volume is more convenient in terms of movement than traditional large medical equipment. It can be flexibly transported to various places in hospitals with complicated personnel and narrow roads. The locking device can ensure that the ultrasonic treatment table will not be extended due to external force when it is in a contracted state. By pressing the side button, the required telescopic part is ejected through the spring device. The parameter adjustment operation table is set at the front end of the main frame of the LIPUS fracture interventional treatment trolley, and the parameters required for treatment can be adjusted in time according to the specific weight and BMI parameters of the patient, so as to achieve symptomatic treatment in the true sense. The bottom is an ultrasonic radiation device, which is connected to five ultrasonic probes. At the same time, the five ultrasonic probes can be fixed to the ultrasonic probe mounting plate through a threaded connection. Because the degree of injury in the deep tissue of the patient is different, stronger ultrasonic mechanical stimulation is often required. Therefore, the number of ultrasonic probes is increased to five to facilitate the postoperative rehabilitation of patients with severe injuries in the deep tissue or the injured area and large-area trauma of the surgical skin.

[0007] The present invention is achieved through the following technical solutions:

[0008] A low-intensity pulsed ultrasound (LIPUS) fracture interventional treatment table; comprising: a table main frame, an extension frame, a LIPUS radiation device, a LIPUS control device, a locking device and a moving device;

[0009] The trolley main frame is the main frame body, which is used to control the direction during movement and carry the LIPUS radiation and control device;

[0010] The extension frame is used for extending and retracting the treatment table, so that adult patients can be treated in a proper posture;

[0011] The LIPUS control device is used to control the LIPUS irradiation frequency, duty cycle and sound intensity;

[0012] The locking device is used to provide horizontal constraints on the trolley main frame and the extension frame;

[0013] The moving device is used to fix and move the main frame and the extension frame of the trolley;

[0014] The LIPUS radiation device includes an ultrasonic transducer, an internal electrical energy storage element and a mechanical vibration system. The internal electrical energy storage element mainly changes the electric field or magnetic field according to the electric oscillation signal transmitted by the excitation power supply. This change will generate an electric field force or a magnetic force, thereby giving the vibration system a driving force to cause the vibration system to enter a vibration state. The vibration generates mechanical waves (ultrasound waves), which then radiate sound waves to human tissues.

[0015] In the above technical solution, the main frame of the trolley includes smooth balls, end baffles, bottom LIPUS radiation device placement slots, moving handrails, extension frame expansion slots, smooth balls required for the movement of the extension frame, spring clips, and threaded holes for the bottom moving device of the trolley; the smooth balls are placed on the upper left and upper right of the ultrasonic irradiation trolley and are symmetrically distributed. The end baffle ensures good contact between the end of the extension frame and the end of the smooth ball trolley main frame slot to achieve the fixing effect after the extension is completed; the bottom LIPUS is to install the LIPUS radiation box at the bottom of the trolley for easy movement with the treatment trolley. The extension frame expansion slot provides good space compression capacity for the extension frame and the main frame; the smooth ball required for the movement of the extension frame is fixed and symmetrically distributed with the left and right ends of the extension frame expansion slot in the main frame, and there is an end slot in the middle to ensure that the bottom slide rail can continue to move after moving to the end.

[0016] In the above technical solution, the LIPUS radiation device can select the appropriate number of ultrasonic transducers according to the specific treatment area required by the patient and fix them on the ultrasonic transducer buckle for treatment.

[0017] In the above technical solution, the mobile device can fix the LIPUS treatment table to the ground through a pedal, and the position of the treatment table can be adjusted by releasing the pedal.

[0018] In the above technical solution, the locking device can provide fixed constraints on the main frame and the extended frame in the horizontal direction, and the locking device buckle can be released by pressing the locking button to achieve the effect of releasing the constraint.

[0019] In the above technical solution, a ball bearing slide rail is provided at the bottom of the extension frame to facilitate the complete fit of the protruding part of the extension frame with the extension frame expansion slot of the trolley main frame to achieve the effect of optimizing the use of space, and a spring rod is provided in the center of the complementary part of the extension frame expansion slot of the main frame to ensure that the locking effect is achieved after being released from the main frame.

[0020] In the above technical solution, the LIPUS control device can adjust the irradiation frequency (f), duty cycle (DC) and sound intensity parameters of LIPUS to suit different patients.

[0021] The advantages and beneficial effects of the present invention are:

[0022] The main frame and the extension frame of the treatment table designed by the present invention have simple structures, are easy to process and install, and are mostly made of plastic materials, which are low in cost and easy to mass produce.

[0023] The LIPUS used in the present invention has been proven to be a "green" health physiotherapy program with no side effects. It can have a good postoperative rehabilitation physiotherapy effect on both superficial and deep tissues. The present invention combines a new telescopic treatment trolley with LIPUS to provide a new physiotherapy program for postoperative trauma patients and a low-cost, high-treatment-effect medical device for hospitals and medical device companies.

[0024] The present invention combines the LIPUS radiation device with a control device to perform parameter regulation according to the patient's specific physical fitness and body tissue content, breaking away from the traditional fixed-parameter ultrasound treatment plan and achieving truly customized treatment.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0032] A low intensity pulsed ultrasound (LIPUS) fracture interventional treatment table comprises a main trolley frame, an extension frame, a LIPUS radiation device, a LIPUS control device, a locking device and a moving device.

[0033] The main frame 1 of the treatment table includes a main frame bearing surface 101, a movable armrest 102, a spring buckle 103, an upper ball 104, and a bottom ball 105; the main frame 101, the main frame bearing surface 102, the movable armrest 102, the spring buckle 103, the upper ball 104, and the bottom ball 105 are connected by threads, ordinary matching and welding to form the entire main frame of the treatment table. The upper ball 104 and the bottom ball 105 are matched to reduce friction, and are used to match 601 and 604 to reduce rolling friction. The movable armrest 102 is threadedly connected to the main frame bearing body 101, and multiple movable armrests 102 are welded with metal materials. The spring buckle 103 is connected to the main frame by ordinary matching.

[0034] The LIPUS radiation device includes a telescopic hose 201, an ultrasonic transducer 202, and an ultrasonic transducer buckle 203. The LIPUS radiation device is placed in a groove at the bottom of the main frame of the treatment table 1, and five telescopic hoses 201 extend externally. The LIPUS control device 3 can adjust the parameters required for treatment, and is fixed on the ultrasonic transducer buckle 203 through a threaded connection according to the required number of ultrasonic transducers 202.

[0035] The LIPUS control device comprises 301; touch buttons, 302; control circuit, 303; control circuit box; the control circuit box 303 is used to adjust the required current size for the internal energy storage element of the ultrasonic transducer to control the vibration frequency output by the vibration system; the control circuit 302 is placed in the metal support tube through internal wiring and extends upward to the upper control panel, and the touch buttons 301 are arranged in three columns, namely LIPUS frequency, duty cycle and sound intensity, and the required parameters of LIPUS are controlled by touching the buttons.

[0036] The mobile device includes a locking pedal 501, a wheel hub 502, a rubber wheel 503, and a mounting thread 504. The parameters of the mounting thread 504 are 30 turns with a pitch of 0.8 mm; the rubber wheel 503 and the wheel hub 502 are connected by ordinary rods, and the end of the locking pedal 501 is fixed to the wheel hub 5.2 by nuts and bolts.

[0037] The telescopic frame includes a ball-bearing slide rail 601, a spring rod member 602, a bottom baffle plate 603, and a bottom ball-bearing slide rail 604; the ball-bearing slide rail 601 cooperates with the balls of the main frame 104 of the treatment table to reduce the friction during extension and retraction, the spring rod member 602 and the spring buckle 103 contact each other to achieve horizontal constraint between the main frame of the treatment table and the telescopic frame; the bottom baffle plate 603 ensures contact with the bottom card slot of the main frame of the treatment table to reach the maximum extension state, and the bottom ball-bearing slide rail 604 contacts with the bottom balls of the main frame 105 of the treatment table.

[0038] The use process of the present invention: Before the treatment begins, the medical staff needs to open the spring buckle of the main frame 104 of the treatment table and drag the extension frame to increase the area of ​​the treatment table. After the extension is completed, step on the locking pedal of the moving device 501 to fix it below, observe the approximate thickness of the patient's soft tissues such as fat and muscle according to the diagnostic CT film, adjust the treatment parameters required by the 3LIPUS control device according to the needs, including the ultrasound irradiation frequency, duty cycle and sound intensity, and select the appropriate number of 202 ultrasonic transducers according to the patient's physical therapy area and fix them with the 203 ultrasonic transducer buckle for treatment. After use, push the 6 extension frame and the 1 main frame to lock them at the locking device, and push the 102 moving armrest to place the LPIUS fracture interventional treatment table elsewhere.

[0039] On the basis of the above discussion, it should be added that, since the material of the telescopic frame of the treatment table is relatively thin, in order to provide a higher load-bearing capacity of the extension frame, it is recommended to use high-strength material as the manufacturing material.

[0040] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the elements described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0041] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0042] The present invention is described above by way of example. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by those skilled in the art without inventive effort falls within the protection scope of the present invention.
