Multi-section 3D printed artificial rib with retractable structure

Abstract

The invention relates to the field of medical instruments, in particular to a retractable multi-section 3D printed artificial rib. An artificial rib body comprises a double-mortise structure, a single-mortise single-tenon structure, a single-mortise structure with spherical joints and a single-tenon structure with spherical joints; sliding mortises are used for connection, the multi-section combination between the artificial rib and human ribs or between the artificial rib and other artificial ribs is achieved, and the retractable multi-section artificial rib which conforms to the curvature ofthe human ribs is formed. The artificial rib is mainly used for replacing a lesion rib and can be passively lengthened or shortened along with extension and retraction of the thorax, the movement ofthe thorax is not restricted any longer, the requirement of anatomical functional repair of the ribs is met, the influence on the physiological functions of the rib is minimized at the same time, andthe physical fitness and life quality of patients are improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a multi-segment 3D printed artificial rib with a stretchable structure. 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. [0003] 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. The contents include heart, lung, trachea, bronchi, mediastinum and other important internal organs. The back of the thorax is the spine, the ribs and intercostal spaces are on the sides, and the sternum is in the front. The thorax has a certain degree of elasticity and mobility, which plays a role in supporting and...

Problems solved by technology

This will lead to the following adverse consequences. On the one hand, the bare sliding groove will not slide normally due to the attachment and growth of cell tissue, or even embedded in the groove.

On the other hand, the top of the protruding screw will rub against the pleural surface of the chest wall as the ribs slide during breathing, and the constant friction may lead to pleurisy. Because the nerves of the pleura are very sensitive, it may cause obvious pain when the patient breathes. chest pain
