Abstract

The invention discloses an arc-shaped external fixator for soft tissue traction. The arc-shaped external fixator for soft tissue traction is characterized by comprising a pair of arc-shaped guide rails, an arc-shaped rack, a sliding bar pin clip, a fixed bar pin clip, a worm, a clamp spring and multiple Z-shaped bone pins, wherein the sliding bar pin clip and the fixed bar pin clip are arranged on the two sides of the arc-shaped guide rails respectively in a sleeving mode, the worm is screwed to one end of the arc-shaped rack and the fixed bar pin clip, the clamp spring is arranged at the tail end of the worm in a sleeving mode, the Z-shaped bone pins are arranged on the sliding bar pin clip and the fixed bar pin clip, and the worm meshes with the arc-shaped rack through threads on the worm. In use, soft tissue can be pulled along an arc-shaped track, so that the arc-shaped external fixator for soft tissue traction is suitable for traction of soft tissue of cylindrical muscle or body, cutting of skin or soft tissue is avoided, and secondary injury is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an arc-shaped soft tissue pulling external fixator. Background technique [0002] The soft tissue traction external fixator is mainly used in the traction repair surgery of skin, muscle and tendon soft tissue in clinical practice. It is used to stretch the soft tissue with large defect or local skin for covering traction, and finally achieve the effect of skin coverage. [0003] At present, the soft tissue stretching external fixators used clinically are all straight soft tissue stretching external fixators. For example, patent document 201510026674.3 discloses a soft tissue stretching external fixator, and this fixation frame is only suitable for soft tissues of the planar body or small areas. The stretching of soft tissue defects is not suitable for the cylindrical surface of the body. When it is used on the cylindrical surface of the body, it is easy to cause repeated contact be...
