Abstract

The invention discloses a bone preventive reinforced minimally invasive treatment method based on controllable minimally invasive damage and a serialization instrument, and relates to the technical field of orthopedics minimally invasive. The invention realizes the self-repair and reconstruction of bone tissue by implementing percutaneous low-speed shallow hole drilling in a safe area through preoperative image positioning and utilizing controllable micro-damage to excite bone tissue to strengthen bone density and bone structure, and is matched with a serial limiting drilling device, thereby having multiple-diameter and multiple-depth specifications, being capable of accurately selecting according to different positions and different bone thicknesses and ensuring not to penetrate bone cortex and not to damage bone marrow. The invention has the advantages of extremely small wound, simple and convenient operation, safety and high efficiency, is suitable for early intervention and radical reinforcement of osteoporosis, early femoral head necrosis and knee osteoarthritis, and has extremely high clinical popularization value.

Description

Bone preventive strengthening minimally invasive treatment method based on controllable minimally invasive damage and serialization instrument Technical Field The invention relates to the technical field of minimally invasive surgery in orthopaedics, in particular to a minimally invasive treatment method for realizing self-reinforcement of bones through controllable shallow micropore stimulation and a matched special instrument. Background At present, the clinic lack of early, minimally invasive and preventive radical treatment means for diseases such as osteoporosis, femoral head necrosis, knee osteoarthritis and the like. The medicine can not promote bone density, the operation replacement wound is big, and traditional drilling technique can not accurate control degree of depth, easily causes penetration, infection, neurovascular damage. The present invention solves the pain point. Disclosure of Invention The invention discloses a bone preventive strengthening minimally invasive treatment method, which comprises the steps of measuring the thickness of bone cortex through preoperative images, performing percutaneous low-speed shallow hole drilling in a joint extension safety area, manufacturing controllable micro-damage, exciting a human body self-repairing mechanism, and realizing local bone density improvement, blood circulation reconstruction and structure strengthening. The invention also discloses a serial special limiting drilling device which comprises various diameters and various limiting depth specifications, is flexibly selected according to different positions and different bone thicknesses, ensures that the drilling does not penetrate through cortical bone, does not damage bone marrow, and has extremely small wound and extremely high safety. The technical scheme includes that 1, the thickness of the bone cortex and a safe operation area are determined through X-ray/CT before operation, 2, a limiting drilling device with corresponding specification is selected, 3, percutaneous penetration is carried out to the bone surface, drilling is carried out at a low speed, 4, depth is controlled to be 50% -80% of the thickness of the bone cortex, no penetration and no marrow feeding are carried out, 5, bone reinforcement is completed through simple bundling after operation by utilizing a self-healing mechanism. The bone fracture repair device has the beneficial effects of minimally invasive, painless, quick recovery, absolute and controllable depth, no penetration risk, suitability of the serialization apparatus for all bone parts of the whole body, excitation of self-repair, reinforcement of bones from root sources, and suitability for high risk groups of early femoral head necrosis, gonarthritis and osteoporosis. Drawings FIG. 1 is a schematic flow chart of the treatment method of the present invention; FIG. 2 is a schematic diagram of the special spacing drilling apparatus of the present invention. Detailed Description The method comprises the steps of performing imaging measurement on a target part to determine the thickness of a safe area and bones, sterilizing and locally anesthetizing, selecting a limit drill bit with a matched specification, performing percutaneous until reaching the bone surface, performing low-speed drilling until a limit cap automatically stops limiting, performing aseptic bandaging, recovering 3-7 days after operation, and remarkably improving the bone density for 3-6 months.
