摘要:
The present invention relates to an expandable device for vertebral or intervertebral support reduction, and more particularly to an implant designed for vertebral or intervertebral damage deformation and reconstruction of a condition for use in a minimally invasive manner. Into the vertebral body or intervertebral tissue; the expandable device may comprise one or more visible shapes of the patient to form an expandable device, such as a stent, implant, etc., which may comprise any geometric design; The expansion device may be a non-hollowed flat plate body, such as a cylindrical body, a bullet shape, a kidney shape, a curved body (such as a banana type), a rectangular body, a spherical body, etc., or may be wound to form any geometric shape, or The hollow flat plate body with a fine pore distribution on the surface may be formed by winding any geometric shape, such as a cylindrical body, a bullet shape, a kidney shape, a curved body (such as a banana type), a rectangular body, a spherical body, or the like; The material used in the planar plate body is a shape formed by a nitriding biocompatible shape memory alloy such as nickel-titanium alloy, whereby the characteristics of the shape memory alloy are constant. In the temperature range, the bundled state and the expanded state are generated, and the various bone cement or chondrocytes or bone matrix or artificial bone or tannin is filled in an expanded state, thereby achieving the effect of vertebral body or intervertebral reduction and allowing the patient to reduce bed rest. The time of hospitalization, the purpose of returning to normal life and work early.本創作係有關一種椎體或椎間支撐復位之可擴張裝置,尤指一種針對椎體或椎間損壞變形及重建病症所設計的植入物件,其用於以最小侵害之方式,作於植入椎體或椎間組織內;該可擴張裝置可包括一個或一個以上可視病患所需形體而成型一可包含任何幾何形狀設計的可擴張器件,例如支架、植入物等;上述該可擴張裝置可為一非鏤空的平面板體,作以捲繞成型一任何幾何形狀者,如圓柱形體、子彈形體、腎形體、彎曲形體(如香蕉型)、長方形體、圓球形體等,或可為一表面分佈細孔的鏤空平面板體,作以捲繞成型一任何幾何形狀者,如圓柱形體、子彈形體、腎形體、彎曲形體(如香蕉型)、長方形體、圓球形體等;上述該平面板體所使用的材質係屬一表面具氮化處理的生物相容形狀記憶合金如鎳鈦合金所製作成型者,藉以形狀記憶合金的特性在一定的溫度範圍內產生束收狀態與擴張狀態,並藉以擴張狀
