Embodiment

[0017] Such as figure 1 As shown, a multifunctional self-locking orthopedic external fixator includes clamping unit A1 and clamping unit B8 arranged at both ends, and a main body rotation mechanism A and Main body rotation mechanism B. Angle adjustment units are respectively arranged between the main body rotating mechanism A and the clamping block unit A, and between the main body rotating mechanism B and the clamping block unit B.

[0018] In this embodiment, the angle adjustment unit includes a worm gear device 2 respectively connecting the main body rotation mechanism A and the clamp unit A1 , the main body rotation mechanism B and the clamp unit B8 , and the worm gear device 2 is provided with an adjusting screw 9 . Wherein, considering the practical application, the clamping unit A is a T-shaped clamping unit, and the clamping unit B is a five-needle clamping unit.

[0019] In this embodiment, the main body rotating mechanism A includes a rotating main body A3 connecte...

Abstract

The invention discloses a multifunctional self-locking type orthopedic outer fixing frame which comprises a block clamping unit A and a block clamping B. The block clamping unit A and the block clamping B are respectively arranged at two ends of the multifunctional self-locking type orthopedic outer fixing frame which is characterized in that a main body rotary mechanism A and a main body rotary mechanism B are arranged between the block clamping A and the block clamping B, an angle adjusting unit is arranged between the main body rotary mechanism A and the block clamping A, and an angle adjusting unit is arranged between the main body rotary mechanism B and the block clamping B. As an improvement, the angle adjusting units comprise worm and gear devices provided with adjusting screws. the main body rotary mechanism A and the block clamping A are connected through the worm and gear devices, and the main body rotary mechanism B and the block clamping B are connected through the worm and gear devices. The multifunctional self-locking type orthopedic outer fixing frame is reasonable in design, simple in structure, and capable of achieving fine adjustment, moreover guarantees recovery effect, and meanwhile has multiple chooses on the block clamping units, achieves multiple purposes, and greatly reduces using cost.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a multifunctional self-locking orthopedic external fixator. Background technique [0002] The external fixator is an external fixation device that does not directly contact the human skin. According to different fractures or deformities in the human body, different external support structures are assembled. Longitudinal rods (tubes) and / or rings are connected to act on local bone parts to achieve plane and three-dimensional support fixation, thereby playing the role of stabilization, reduction, compression or traction extension, and correction of angular deformities, thereby assisting fractures Therapeutic effect in healing or correcting deformities. However, the existing external fixation bracket cannot be fine-tuned during use, and the fixed part will become loose after long-term use. The looseness of the fixed part will affect the correction effect and affect the ...
