Description

Technical Field

[0001] The present invention relates to the technical field of targeted therapy, in particular to a stem cell guided static fixation device based on magnetic targeting technology. Background Art

[0002] With the development of magnetic nanomedicines, applying an external magnetic field to improve the targeting efficiency of magnetic nanomedicines has become an important and safe physical intervention strategy.

[0003] There are two traditional methods of applying an external magnetic field. One is to use a permanent magnet attached to the skin of the patient's lesion site. Although this treatment method is low-cost, it is not easy to control the magnetic strength. The other is to use an electromagnet to be placed at the patient's lesion site, and change the magnetic field strength by the current size to adjust to the magnetic field strength suitable for different drugs. However, the ring formed by this electromagnet is not easy to adjust the position and can only move in the horizontal direction. Different lesion locations require different deflection angles to ensure better magnetic field targeting effect. If there is a deviation in the magnetic field angle, it is easy to affect organs in other normal parts and reduce the efficacy of stem cell targeted therapy. Moreover, the size of the electromagnet itself is not easy to adjust, so the size of the magnetic field cannot be adjusted according to the size of the lesion site, which affects the treatment effect. In response to the shortcomings of the existing technology, the present invention provides a stem cell guided static fixation device based on magnetic targeting technology to solve the above problems. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the present invention provides a stem cell guidance static fixation device based on magnetic targeting technology, which is convenient for assembling or storing the entire device. After the entire device is assembled, an electromagnetic induction coil is used to provide magnetic targeted stem cell guidance to the patient's lesion site. The electromagnetic induction coil is not only convenient for disassembly and assembly to replace different sizes and models to adapt to lesions of different sizes, but also the rotation angle of the electromagnetic induction coil and the left and right and up and down angles can be flexibly adjusted. The height of the electromagnetic induction coil is also convenient to adjust, so that the electromagnetic induction coil can be conveniently facing the patient's lesion site and the position and angle of the electromagnetic induction coil can be kept stable. The strength of the magnetic field is adjusted by adjusting the current passed into the electromagnetic induction coil, so that the stem cell guidance process of the magnetic targeting technology is stable, ensuring that the magnetic targeting positioning of the drug delivery treatment effect is good.

[0061] Working Principle: This stem cell guided static fixation device based on magnetic targeting technology is easy to assemble and store as a whole. When storing the device as a whole, the carrier frame 3 and the lifting adjustment seat 2 are disassembled, the fixed clamping column 8 and the angle adjustment seat 7 are disassembled, and then the carrier frame 3, the upper and lower position adjustment shaft 4, the left and right position adjustment shaft 5, the adjustment arm 6, the angle adjustment seat 7, the fixed clamping column 8, the connecting rod 9 and the electromagnetic induction coil 10 are placed in the storage compartment 104 for storage. At the same time, the device is disinfected and sterilized by the ultraviolet germicidal lamp 106 to ensure the hygiene of the device.

[0062] During use, the device is easy to assemble quickly, and the height and XYZ axis deflection angle of the electromagnetic induction coil 10 can be adjusted and fixed in position at the same time, thereby achieving the goal of using the induced magnetic field generated by the electromagnetic induction coil 10 to face the lesion site while maintaining the position and angle of the electromagnetic induction coil 10 stable. The intensity of the magnetic field is adjusted by adjusting the current flowing into the electromagnetic induction coil 10, thereby stabilizing the stem cell guidance process of the magnetic targeting technology and ensuring good magnetic targeting drug delivery treatment effects.

[0063] When assembling the entire device, first fix the first mounting plate 204 and the second mounting plate 301 with bolts, then insert the fixed clamping column 8 into the fixed clamping slot 701, and pull the unlocking handle 1104 upwards at the same time, so that the unlocking handle 1104 drives the slider 1101 and the locking rod 1102 to move upwards and squeeze the spring 1103 at the same time. When the fixed clamping column 8 is fully inserted into the fixed clamping slot 701, release the unlocking handle 1104, and use the restoring elastic force of the spring 1103 to push the slider 1101 and the locking rod 1102 to move, so that the locking rod 1102 is inserted into the locking hole 801, thereby fixing the fixed clamping column 8, the connecting rod 9 and the electromagnetic induction coil 10 on the adjusting arm 6 and the angle adjustment seat 7;

[0064] Furthermore, the rotation angle of the electromagnetic induction coil 10 is adjusted so that the electromagnetic induction coil 10 is facing the patient's lesion. After the adjustment is completed, the rotation handle 705 is rotated to drive the second screw rod 703 to rotate, and the second screw rod 703 is used to push the arc-shaped clamping and positioning block 704 to move and clamp the arc-shaped clamping and positioning block 704 to limit the connecting rod 9, thereby achieving a fixed angle between the connecting rod 9 and the electromagnetic induction coil 10.

[0065] Furthermore, the height of the electromagnetic induction coil 10 is adjusted by driving the motor body 203, which drives the first screw rod 202 to rotate, and the first screw rod 202 drives the lifting adjustment seat 2 to move, and the lifting adjustment seat 2 drives the supporting frame 3, the upper and lower position adjustment shaft 4, the left and right position adjustment shaft 5, the adjustment arm 6, the angle adjustment seat 7, the fixed clamping column 8, the connecting rod 9 and the electromagnetic induction coil 10 to move up and down as a whole, thereby achieving the height adjustment of the electromagnetic induction coil 10;

[0066] When adjusting the left and right and up and down inclination angles of the height of the electromagnetic induction coil 10, the first electric push rod 402 and the second electric push rod 502 are used. When the first electric push rod 402 is working, it drives the first rack 403 to move, and the first rack 403 drives the first gear 401 to rotate. The first gear 401 drives the upper and lower position adjustment shafts 4 to rotate, and the upper and lower position adjustment shafts 4 drive the left and right position adjustment shafts 5, the adjustment arm 6, the angle adjustment seat 7, the fixed clamping column 8, the connecting rod 9 and the electromagnetic induction coil 10 to rotate as a whole, thereby achieving the up and down angle adjustment of the electromagnetic induction coil 10;

[0067] When the second electric push rod 502 is working, it drives the second rack 503 to move relative to the second gear 501, so that the adjustment arm 6 rotates along the left and right azimuth adjustment axis 5. Then, the adjustment arm 6 drives the angle adjustment seat 7, the fixed clamping column 8, the connecting rod 9 and the electromagnetic induction coil 10 to rotate as a whole, thereby achieving left and right angle adjustment of the electromagnetic induction coil 10;

[0068] In summary, the stem cell guidance static fixation device based on magnetic targeting technology is convenient for assembling or storing the entire device. After the entire device is assembled, the electromagnetic induction coil 10 is used to provide magnetic targeted stem cell guidance to the patient's lesion site. The electromagnetic induction coil 10 is not only convenient for disassembly and assembly to replace different sizes to suit lesions of different sizes, but also the rotation angle of the electromagnetic induction coil 10 and the left and right and up and down angles can be flexibly adjusted. The height of the electromagnetic induction coil 10 is also convenient to adjust, so that the electromagnetic induction coil 10 is convenient to face the patient's lesion site and keep the position and angle of the electromagnetic induction coil 10 stable. The strength of the magnetic field is adjusted by adjusting the current passed into the electromagnetic induction coil 10, so that the stem cell guidance process of the magnetic targeting technology is stable, ensuring that the magnetic targeting positioning drug delivery treatment effect is good.
