the standard block pin hole of standard block and the fixed block pin hole in the special block that one side is connected pass through fixed pin and connect, standard block pin hole two and the special block that the opposite side is connected in the movable block pin hole pass through fixed pin and connect.
Further, the width and radian of the external cambered surface of the fixed block and the width and radian of the cambered surface of the main body part of the standard block are equal.
Furthermore, the number of the standard blocks and the number of the special blocks can be increased according to requirements, and the corresponding arc length can be correspondingly reduced.
The movable block pin hole and the fixed block pin hole are both used as mounting holes.
And the mounting holes on the special block and the standard block are used for mounting an additional device, and the additional device comprises an expansion link and a steel needle clamp.
The beneficial effects of the utility model are that:
1. the utility model discloses the taylor frame of constitution can regard as a skeleton centering instrument, and the patient can select internal fixation steel sheet or other fixed modes by oneself after the centering is accomplished
2. The Taylor frame formed by the utility model can vacate operation space for other operations when the patient has other operation demands near the affected part
3. The utility model discloses can change the use form of current taylor frame, need not follow the form of installing ring reloading pole earlier or external design completion integral erection again, can freely select the installation order according to the patient's condition, and the selection degree of freedom is bigger
4. The utility model relates to an external fixation support ring reuse rate is high, can retrieve the spare part of external fixation support ring after the patient fully recovers, and this will reduce treatment cost effectively.
5. The utility model relates to an outer fixed bolster ring though only provide the quick assembly disassembly of ring, but through the dismouting to the piece that links to each other with the telescopic link, also can realize the quick assembly disassembly of telescopic link, and the range of application is wider.
6. The utility model discloses it is compatible strong, can use all kinds of structures of current taylor frame to need not to customize again.
