A device for treating diabetic foot

Abstract

The invention discloses a device for treating diabetic foot, which comprises at least two first elastic struts, at least one support rod, and at least two magnetically controlled telescopic rods; at least two deformable frames are formed in the device, and the support rod pairs can The deformable frame plays a supporting role; the device of the present invention regulates the elongation and shortening of the magnetically controlled telescopic rod through a magnetic field, so that the deformable frame is deformed, thereby achieving stretching of the periosteum and promoting blood vessel repair. The device has a simple structure, and when used, it is implanted into the human body and adopts external regulation, which can effectively prevent infection and achieve precise adjustment functions. In addition, the device of the present invention can also be equipped with bone needles to further realize bone marrow participating in the repair of blood vessels, Reconstruction is beneficial to the treatment and recovery of diabetic foot.

Description

technical field [0001] The invention belongs to the field of medical technology, and relates to a diabetic foot treatment device and a using method thereof. Background technique [0002] Diabetic foot and other diseases can easily cause limb ischemia, pain and necrosis. Many patients have to amputate their limbs, and even after amputation, the wound will not heal. , vascular stents and other treatment methods to rebuild the microcirculation of limb tissues. [0003] In recent years, the widely used transverse bone transport technique is an effective way to treat diabetic foot. This technology stimulates the regeneration and recanalization of local bone, soft tissue and blood vessels through slow and continuous tension stimulation. However, the transverse bone transport technique is complicated to operate during the operation and requires fine manipulation to separate a section of bone. Regulates the regeneration and recanalization of blood vessels by stimulating the isola...

Problems solved by technology

[0005] The above two technologies generally involve relatively large defects and high risks in the equipment products; first, the products need to use Kirschner wires on the cortical bone for positioning and retractor-shaped bone needles for bone transportation, and one side enters the bone. The other side is exposed to the air, which is likely to cause bone infection; secondly, the driving part of the adjustment screw is often exposed outside the skin, and the overlapping part of the thread and the skin is always in contact with the outside air, which is also easy to cause infection; and usually the screw is Full thread, there is no effective limit to the lifting distance, there is a possibility of misoperation, too much lifting will not only cause treatment failure, but also increase complications, so the adjustment accuracy and quality depend on the doctor's work experience
