Guide plate for sternum reconstruction and manufacturing method of guide plate

Abstract

The invention relates to a guide plate for sternum reconstruction and a manufacturing method of the guide plate. The sternum guide plate is composed of a movable push plate and a guide plate body, wherein the movable push plate comprises a part corresponding to the sternum of the push plate, and a part corresponding to the rib of the push plate, and a plate taking arch hole is formed in the back of the part corresponding to the sternum of the push plate; the guide plate body comprises a part corresponding to the sternum of the guide plate body, and a part corresponding to the rib of the guide plate body, a lifting handle is arranged on the back of the guide plate body, a slot is formed in the part corresponding to the sternum of the guide plate body, and a gap for injecting bone cement is arranged between the part corresponding to the sternum of the guide plate body and the rib of a patient. The manufacturing method of the guide plate comprises the following steps: determining the reconstruction part of the sternum; generating the sternum guide plate composed of the movable push plate and the guide plate body; printing the movable push plate and the guide plate body; and finally, carrying out disinfecting for later use. According to the scheme, a nylon material and 3D printing are adopted, the integral guide plate is designed in a manner that the movable push plate and the guide plate body are matched for use, and the separate taking-out manner is adopted, so that the problem that the bone cement auxiliary part can not be taken out easily is solved.

Description

technical field [0001] The invention relates to a medical clinical auxiliary appliance, in particular to a guide plate for sternal reconstruction and a manufacturing method thereof. Background technique [0002] The sternum is a flat bone located in the middle of the anterior chest wall, shaped like a short sword, and divided into three parts: hilt, body, and xiphoid process. Both sides of the sternum are connected with the ribs to form the thorax, which plays an important role in protecting the mediastinum and internal organs of the thoracic cavity. Common sternal diseases such as sternal tumors, infections, radiation ulcers, trauma, and congenital deformities often require surgical treatment, resulting in sternal defects. In severe cases, the entire sternum needs to be removed. The integrity and stability of the thoracic cage and the protection of the mediastinal organs were destroyed, endangering the life of the patient. The sternum needs to be reconstructed. At present...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that bone cement is the main material for sternal reconstruction, but because the bone cement is very viscous and hardens quickly, after using auxiliary equipment, how to remove the auxiliary equipment has become a major problem in clinical operations.
