A microsurgical device and a usage method thereof can be used for the treatment of various conditions including eye diseases, such as glaucoma, by using minimally invasive surgical techniques. A dual-blade device can be used for cutting the trabecular meshwork (TM) in the eye. The device tip provides an entry into the Schlemm's canal via its size (i.e., for example, 0.2-0.3 mm width) and configuration where a ramp elevates the TM away from the outer wall of the Schlemm's canal and guides the TM to first and second lateral elements for creating first and second incisions through the TM. The dimensions and configuration of the blade is such that the entire strip of TM is removed without leaving TM leaflets behind and without causing the collateral damage to the adjacent tissues. 一种显微外科手术装置及其使用方法可用于使用微创外科技术治疗各种病症，包括眼病，比如青光眼。双刀片装置可用于切割眼睛中的小梁网("TM")。装置末端通过其尺寸(即，例如，0.2-0.3mm宽)和构造提供进入巩膜静脉窦的入口，在其构造中，斜坡将TM远离巩膜静脉窦的外壁地提升，并将TM引导至第一横向元件和第二横向元件，以产生穿过TM的第一切口和第二切口。刀片的尺寸和构造使得整个TM条带被移除，而不会留下TM小叶，并且不会对邻近组织造成附带损伤。
