Chinese and western combined adjustable orthopedic external fixation frame

Abstract

The invention relates to the technical field of orthopedic medical apparatuses and instruments, and discloses a Chinese and western combined adjustable orthopedic external fixation frame. The Chinese and western combined adjustable orthopedic external fixation frame comprises a first connecting column and a second connecting column; a first mounting groove is formed in the first connecting column; a first rotating block is movably mounted inside the first mounting groove; a first telescopic rod is fixedly mounted on one side of the first rotating block. According to the invention, by rotating the first rotating rod, the first rotating rod can drive a second gear to rotate in the rotating process, and the second gear can drive a rotating shaft to rotate by a first gear in the rotating process; and a screw thread is formed at the outer side end of the rotating shaft, and threaded grooves matched with the rotating shaft are formed inside a second telescopic rod and a second rotating block, so that the rotating shaft can drive the second telescopic rod to extend out by the length of the second connecting column in the rotating process, and the included angle between the first telescopic rod and the second telescopic rod can be changed through a first rotating shaft block to adapt to wounds at different positions.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to an adjustable orthopedic external fixator combining Chinese and Western techniques. Background technique [0002] As the incidence of traffic accidents in society is getting higher and higher, once serious traffic accidents occur, they will be fatal, and light ones will also cause fractures and other problems. Especially in recent years, the orthopedic wards of hospitals are overcrowded. How to treat orthopedic patients It is particularly urgent to carry out effective treatment and protection, and most of the bone injuries now require fixed treatment, so in the case of physical therapy in the later stage, it is generally chosen to fix the regressed or bone injured parts, thinking that the fixation method is to use Bandages or other protective gear for protection. [0003] After retrieval, Chinese Patent No. CN209695348U discloses an adjustable orthopedic exter...

Problems solved by technology

[0003] After retrieval, Chinese Patent No. CN209695348U discloses an adjustable orthopedic external fixator, including a plurality of support rods, the ends of two adjacent support rods are connected by a rotating device, and any one of the support rods is covered A plurality of bone nail bases are provided, and the bone nails are clamped on the bone nail bases, and the rotation rod is hinged with the first lock block to realize the rotation of two adjacent support rods. The second locking block, adjust the second locking block away from or fit on the first locking block, realize the rotation or fixation of two adjacent support rods, and install the bone nail clip on the non-connecting fixing surface of the adjustment seat hole, and the bone nail clip is screwed into the bone nail clip installation hole, which realizes the multi-position and multi-angle installation of the bone nail clip, and can adjust the joint range of motion according to the actual situation of the patient to prevent elbow stiffness, effectively solving the existing problem The problem that the orthopedic external fixator cannot move in the joints of the patient, but this kind of fixator, for different heights and different lengths of the injured area, it is not easy to fix the bone when using this kind of fixator, and this kind of fixator is only A single fixed ring frame fixes the wound, which is easy to cause secondary injury
