[0002] As we all know, the medical treatment of femoral head necrosis is nothing more than the following several options: (1) for avascular necrosis without femoral head collapse (stage I, stage II), generally take corresponding drugs to recover Blood supply, or take the method of surgical decompression or bone grafting, its effect is all not very ideal, often also requires the patient to avoid weight-bearing during treatment, do long-term bed rest, affect work and life; (2) for causing femoral head collapse (Patients with stage III and abov

Embodiment 1

[0012] exist figure 1 Among them, 1. It is a hollow cylindrical (￠8) titanium metal rod (nail). The front part of one end is slightly smaller and pointed. There is a "one" groove, and the length of the porous hollow titanium handle (nail) is 80cm (the hospital selects different lengths of the porous hollow titanium handle (nail) according to the length of the patient's femoral tuberosity to the femoral head through inspection).

[0013] Due to the use of titanium metal, it has stable chemical properties, good adaptability to biological tissues, high strength, non-magnetic, light weight, and does not affect X-ray irradiation; the thread shape is suitable for fixing on bone; the "one" groove is easy to insert Or take it out; the hollow and porous not only ensure the reasonable structure, but also facilitate multiple perfusion of drugs, so that the drugs can penetrate into the necrotic area of ​​the femoral head, promote the reconstruction of the microvascular network, improve th...

Abstract

The invention relates to an orthopedic surgery instrument, in particular to a multi-aperture titanium hollow metal bar (nail) for reconstruction of caput femoris necrosis, biomechanics support and medicine infusion treatment. The multi-aperture titanium hollow metal bar (nail) comprises a metal bar (nail) body and is characterized in that: the hollow titanium metal bar (nail) body is drilled with regular and even holes; the external thread end of the bar (nail) is provided with a transverse groove. As titanium metal is used, the invention has stable chemical performance, good adaptability of biological tissue, high intensity, no magnetism, light weight and no influence on X-ray irradiation; the thread shape is suitable for being fixed on sclerotin; the transverse groove is convenient for being placed in or taken out; hollow and multi-aperture design ensures the reasonable structure, is convenient for infusing medicine for many times, so that medicine can be permeated into the area of caput femoris necrosis to promote reconstruction of capillary net and improve the blood transportation to reconstruct necrosis bone. The invention can treat caput femoris necrosis conveniently, simply and effectively.

Description

technical field [0001] The invention relates to the technical field of orthopedic surgery materials, which is a porous titanium hollow metal rod (nail) capable of reconstructing femoral head necrosis, biomechanical support and drug infusion treatment. Background technique [0002] As we all know, the medical treatment of femoral head necrosis is nothing more than the following several options: (1) for avascular necrosis without femoral head collapse (stage I, stage II), generally take corresponding drugs to recover Blood supply, or take the method of surgical decompression or bone grafting, its effect is all not very ideal, often also requires the patient to avoid weight-bearing during treatment, do long-term bed rest, affect work and life; (2) for causing femoral head collapse (Patients with stage III and above are often treated with artificial joint replacement in medicine, which is unacceptable to many patients, and the economic burden is heavy; (3) memory alloy, trabecul...
