Reset fixing frame for orthopedics department

Abstract

The invention discloses a reset fixing frame for the orthopedics department, and relates to the technical field of medical instruments. The reset fixing frame comprises a first annular frame and a second annular frame which have the same structure and are coaxially arranged; the near ends of the first annular frame and the second annular frame are connected through an internal thread sleeve; and first threads opposite in rotating direction are symmetrically formed in the two ends of the inner wall of each inner threaded sleeve. The first annular frame comprises an outer ring and an inner ring.The outer ring and the inner ring are coaxially arranged, and the opposite surfaces of the outer ring and the inner ring are connected through four fixing round rods which are annularly and evenly arranged. A pressing plate adjusting assembly used for limb connection adjustment is fixed to the side face, opposite to the inner ring, of the outer ring and located in the middle of every two adjacentfixing round rods. Second threads matched with the first threads are formed in the circumferential side face of the inner ring. Through combined use of the first annular frame, the second annular frame, the internal thread sleeves, the pressing plate adjusting assemblies and a guide rod assembly, omnidirectional angle adjustment can be conducted on a limb at the joint.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a reduction and fixation frame for orthopedics. Background technique [0002] In orthopedic treatment, sometimes bone fragments must be centered or re-centered and repositioned with the help of a reset fixation frame to restore the continuity of the bone and the function of the backbone. The fractured or fractured bone heals in a misplaced position, which will cause Acquired deformity caused by improper osseous joint development and dislocation. [0003] The invention with the application number 201710560557.4 discloses a reset fixation frame for orthopedics, which has two fixed chassis, and the effective length of the root support rods whose two ends are respectively hinged on the two fixed chassis can be adjusted. A fixed chassis forms a certain angle, the support rod includes a connecting rod, both ends of the connecting rod have external threads, and the left end of ...

AI Technical Summary

Problems solved by technology

The entire adjustment device is not stable enough in positioning, and can only perform six operations of shrinking and extending, left and right angulation, front and rear angulation, left and right translation, front and rear translation, and rotation. For single-end omnidirectional angle adjustment and stability of limbs There is a missing gap in narrowing the butt
