Abstract

The invention discloses a sternum gathering up holder. The sternum gathering up holder comprises a locking wheel, a male fixing component and a female fixing component, wherein the male fixing component and the female fixing component can be connected together in an inserting mode. The section of the locking wheel is of an olive shape or an oval shape. The male fixing component is provided with an elastic plug and a first paw-shaped hook plate, wherein first saw teeth are arranged at two sides of the elastic plug, a tightening groove is formed in the middle of the elastic plug, and a locking hole which is in transition fit with the outer wall face of the locking wheel is formed in the tightening groove, and the long axis direction of the locking hole is the insert-connect direction of the male fixing component and the female fixing component. The female fixing component is provided with a second paw-shaped hook plate and a plug seat, wherein the plug seat is provided with an inserting groove which is matched with the elastic plug, second saw teeth which are matched with the first saw teeth are arranged on two sides of the inserting groove, the rotatable locking wheel is installed inside the locking hole so as to rotate the locking wheel. When the tightening groove is enlarged, the second saw teeth are meshed with the second saw teeth. When the tightening groove is decreased, the first saw teeth are separated from the second saw teeth. The sternum gathering up holder is not only capable of conveniently adjusting the opened chest gathering up width, but also easy and convenient to fix and stable, and capable of not producing cutting phenomenon to sternum.

Description
