The curved bar is used in the correction of the deformities of the sunken chest (pectus excavatum) and the pigeon’s chest (pectus carinatum).

Materials and Methods: Conventionally, the surgeon shapes pectus bars manually during the surgery by trial/error method. In these surgeries, it may not be possible to give the ideal shape manually each time due to the complex anatomy of the patients’ deformity, which might lead to increases in the operation time and the risk of complications (organ injury, bleeding, etc.). The present invention aims to prepare a customized preoperative bent bar by using the CT coordinates of the deformity by the surgeon via a custom software. Besides, as an alternative method, as usual, the novel automated bender can copy a soft metal template.

Results: We presented this project to a few national and international companies. A national company has decided to take the project seriously about starting the process of producing the automatic bender to be used in the related field. The patent has protection both nationally and internationally.

Conclusions: This patent will probably change the clinical pectus bar bending process providing excellent results with high satisfaction rates for both the patients and the surgeons. Keywords : thoracic wall, congenital abnormalities, patent, tomography, software
