A scalable multi-segment 3D printed artificial rib

Abstract

The invention discloses a telescopic multi-sectional 3D printed artificial rib, which includes a connecting bone. First strut bones are fixedly connected to two sides of the connecting bone. Second strut bones are fixedly connected to the upper sides of the first strut bones, wherein insert grooves are formed in the second strut bones. A third strut bone is disposed in each insert groove. A firstbolt is arranged on one side of each second strut bone. A first screw hole is formed in the side wall of each second strut bone and is corresponded to each first bolt. A connection base is arranged onone side of the connecting bone. Two symmetrically arranged semicircle rings are rotatably connected to the upper side of the connection base. By means of a fixing mechanism, the connecting bone of the artificial rib is fixed. By means of a lifting mechanism, the height of a top plate is adjusted, so that the structure can clamp and fix artificial ribs in different specifications. By means of a holding mechanism, the third strut bones of the artificial rib can be clamped and fixed. Through the simple fixing structure, a doctor can conveniently perform following medical operations.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a retractable multi-segment 3D printed artificial rib. Background technique [0002] In recent years, with the maturity and promotion of 3D printing technology, this technology has gradually entered the medical field from the industrial field, and its promotion has provided new methods and means for the successful diagnosis and treatment of many difficult diseases. Taking orthopedics as an example, according to the knowledge of human anatomy, the thorax is a bony cage-like support composed of the spine, ribs, sternum, and intercostal muscles, and contains important internal organs such as the heart, lungs, trachea, bronchi, and mediastinum. When the intercostal muscles and diaphragm relax, the ribs move in opposite directions, the volume of the thorax shrinks, and the lungs retract accordingly, completing exhalation. However, the lesions of the rib itself, the malignan...

Problems solved by technology

[0004] The purpose of the present invention is to solve some conditional hospitals at home and abroad that exist in the prior art. 3D printing technology has been used to use titanium alloy or special engineering plastics, such as polyaryletherketone materials, etc., to successfully print and produce artificial Ribs, and the replacement of the diseased parts, the existing 3D printed artificial ribs need to be temporarily fixed, but there is no device to fix the artificial ribs, so it is not convenient for the doctor to deal with the shortcomings of the follow-up work, A scalable multi-segment 3D printed artificial rib
