摘要：
A fixing device for intravital lumen, comprises a base (18) and a fixing mechanism (5), fixed on said base (18) wherein, said fixing mechanism (5) comprises a housing (5a), and at least a set of clamping brackets (3) and a rotating shaft (7) wherein, a bracket hole (3b) is formed on each clamp bracket (3), and the rotating shaft (7) passes through said bracket hole (3b) and fixes each set of the clamping brackets (3) on the housing (5a) of the fixing device when the fixing device for intravital lumen is placed inside an intravital lumen (11), a soft tissue (11a) of intravital lumen enters a clearance space (3d), and a force is acted on back ends of at least a pair of the clamping bracket (3) and causes the clamping brackets (3) to rotate around the rotating shaft (7) and the soft tissue in the clearance space (3d) is squeezed and clamped. The fixing device is fixed at multiple points on the wall of intravital lumen, which provides a restriction to the axial rotation of such device in the lumen, enhances the reliability of fixation, and improves the accuracy of locating of device.
