Document Type and Number:
WIPO Patent Application WO/2023/197581
Kind Code:
A1
Abstract:
A connecting rod assembly (100), comprising a double-slit connecting rod (110). The double-slit connecting rod (110) comprises a first connecting ring (111), a first pressing plate (112), a second connecting ring (113), a second pressing plate (114), and a connecting plate (115); the first connecting ring (111) and the second connecting ring (113) are arranged at two longitudinal ends of the connecting plate (115), and the axes of the first connecting ring (111) and the second connecting ring (113) are parallel; the first pressing plate (112) and the second pressing plate (114) are configured to drive the diameter of a first ring hole (a) and a second ring hole (b) to decrease upon being pressed by opposite pressing forces. A double-connecting-rod fixing device, comprising two connecting rod assemblies (100) and a directional column (200). A surgical head frame, comprising a double-connecting-rod fixing device. The first pressing plate (112) and the second pressing plate (114) of the double-slit connecting rod (110) are simultaneously pressed to reduce the diameter of the first ring hole (a) and the second ring hole (b), so that shafts inserted into the first ring hole (a) and the second ring hole (b) can be locked in a single step.
