Combined type prosthesis for breastbone reconstruction

Abstract

The invention discloses a piece of combined type prosthesis for breastbone reconstruction and relates to the technical field of artificial prosthesis. The combined type prosthesis comprises at least two breastbone pieces, the breastbone piece is provided with a left rib clip and a right rib clip, an insert slot is formed in the middle of the lower side of the breastbone piece, a connecting lug capable of being embedded into the insertion slot and matched with the insertion slot is arranged in the middle of the upper side of the breastbone piece, the connecting lug of the lower-side breastbone of the two adjacent breastbone pieces is embedded into the insert slot of the upper-side breastbone, connecting and fixing devices mutually matched are respectively arranged on the connecting lugs and the insert slots of the adjacent two breastbone pieces, a sternoclavicular joint or a breastbone upper fixing block is arranged on the uppermost-side breastbone piece, and a breastbone lower end block or a breast lower fixing block is arranged on the lowermost-side breastbone piece. The combined type prosthesis provides a horizontal support force and a vertical support and limit function and has a good effect of protecting thoracic cavity organs like thoracic cavity, heart and lung; the sizes, the shapes and the installation positions of the component units are adjusted at any time according to the individual differences and operation conditions of patients, the surgical operation saves time and labor, and the operation effect is good.

Description

technical field [0001] The invention relates to the technical field of artificial prostheses. Specifically, it is a prosthesis that can provide lateral support and longitudinal support, has a good decompression effect on the chest cavity, and has a good protection effect on organs in the chest cavity. The operation is simple, time-saving and labor-saving, and postoperative. Combined prosthesis for sternal reconstruction with good rehabilitation effect. Background technique [0002] We know that sternotectomy and reconstruction is a common technique after sternal tumor resection. In order to protect the organs in the thoracic cavity, the method of sternal reconstruction, that is, the "sandwich" method, is widely used in large-area defects, usually in the One layer of polypropylene fiber (Marlex Mesh) or polypropylene textile fiber (Prolene) patch is sutured to the remaining sternum and the medial surface of the ribs, and the second layer completes the rigid reconstruction of ...

AI Technical Summary

Problems solved by technology

After this kind of prosthesis is implanted in the human body, it only provides horizontal support, without vertical support and position limiting function, and has poor decompression effect on the chest cavity and poor protection effect on chest organs such as the heart; the size of the connecting plate and the connecting rod and connection The position of the plate connection is fixed and cannot be adjusted at any time according to the differences between individuals and the size differences of each sternum. The operation is time-consuming and laborious, and the postoperative rehabilitation effect is poor.
