Thoracic surgery rib fracture fixing device

Abstract

The invention relates to the field of medical instruments, specifically to a thoracic surgery rib fracture fixing device. The device comprises a left bone plate and a right bone plate; long circular holes are formed in the middle parts of the left bone plate and the right bone plate; sliding grooves are formed in the inner side walls of the long circular holes; fixing threaded sleeve assemblies are slidably connected into the long circular holes; each fixing threaded sleeve assembly comprises a screw, a threaded sleeve and a limiting block; the threaded sleeves slide in the long circular holesand are in threaded fit with the screws; and sliding blocks in sliding fit with the sliding grooves are arranged on the circumferential outer sides of the threaded sleeves in a front-back symmetry mode. According to the invention, by moving the thread sleeve, the thread sleeve is aligned with the preformed hole; therefore, the screw can be conveniently and accurately nailed into the preformed hole; meanwhile, the angle between the left bone plate and the right bone plate can be adjusted conveniently through clamping fit of the rectangular blocks and the rectangular holes and matching of the guide rods and the guide holes, it is not needed to spend time in selecting matched titanium alloy steel plates, then the left bone plate and the right bone plate are sequentially fixed to the rib, andrapid fixing of the rib is achieved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a rib fracture fixation device for thoracic surgery. Background technique [0002] There are a total of 12 pairs of ribs, which are equally divided on both sides of the chest. The front is connected to the sternum and the back to the thoracic vertebrae to form a complete thorax. When the chest is injured, whether it is a closed injury or an open injury, rib fractures are the most common, accounting for about 100% of thoracic fractures. 90%, in children, the ribs are elastic and not easy to break, but in adults, especially the elderly, the ribs are less elastic and prone to fractures. Rib fractures are generally caused by external violence. When direct violence acts on the chest, rib fractures often occur in the At the affected part, the fracture end breaks inward, and at the same time, the internal organs of the chest are damaged. When indirect violence acts on the chest, such ...

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a rib fracture fixation device for thoracic surgery, which can effectively solve rib fracture sites with different curvatures in the prior art, requiring different types of titanium alloy steel plates, that is, choosing different The curved titanium alloy steel plate takes time to select and match the required titanium alloy steel plate, which is time-consuming and laborious. At the same time, the titanium alloy steel plate usually has two sets of fixed screw holes. The doctor needs to accurately match the screw holes to the reserved holes on the ribs. , thus increasing the difficulty of surgery
