Problems solved by technology

Since the vital capacity of the patient before the operation is not high, the decline in the vital capacity after the operation will greatly limit the patient's ability to engage in high-intensity exercise or physical labor, resulting in a significant decline in the patient's quality of life

Embodiment Construction

[0024] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] figure 1 It is a schematic diagram of the artificial sternum part of the present invention. The artificial sternum includes: an artificial sternum 100 and a first pair of artificial ribs 101 . There are 4 pairs of inner spherical joint chambers 104 on both sides of the artificial sternum 100, simulating the joint chambers of human bones. The chamber openings 105 are located on both sides of the artificial sternum 100, and the openings are square. In addition, several fixing holes 106 are opened on the upper part of the artificial sternum 100 for connecting with the human clavicle or other tissue structures. The number of fixing holes depends on the size of the connecting surface and the requirements of the degree of fastening. One end of the first pair of artificial ribs 101 is provided with a sliding tenon groove 102,...

Abstract

The invention belongs to the field of medical apparatus and instruments, and relates to a 3D printed connecting structure of artificial sternums and artificial ribs with movable joints. The connectingstructure comprises a 3D printed artificial sternum and five pairs of artificial ribs. The artificial ribs are connected to a spherical joint cavity arranged at the side face of the artificial sternum through a spherical joint structure at one end of each artificial rid to form movable structures similar to human joints. The 3D printed connecting structure of the artificial sternums and artificial ribs with the movable joints is mainly used for replacing diseased sternums and ribs, can move within a certain range with the expansion or contraction of a thorax, do not restrict the movement of the thorax and pulmonary lobes, thus it is realized that the repair of the sternum and rib anatomy functions is satisfied, the influence on the physiological function is reduced to the minimum, and patients' physical agility and life quality are improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a 3D printed artificial sternum and artificial rib connection structure with movable joints. 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 thoracic surgery as an example, according to the knowledge of human anatomy, the sternum is located in the center of the anterior chest wall. It is a flat bone with a wide upper part and a narrower lower part. The manubrium sternum is wide at the top and narrow at the bottom, and its lateral margin connects with the first costal cartilage. The body of the sternum is flat and long, rectangular, with notches connecting the 2nd to 7th costal cartilages on both sides. T...
