Endoscopic clip (endoclip) is a metallic mechanical device used in gastrointestinal endoscopy practices with the intention of close mucosal surfaces deprived of the requirement for surgery and sew up. Nowadays, endoclip is accessible in the market predominantly in single firing mode, where the clip can only be used once in a period of process. Due to that, the clip is loaded to its applicator repeatedly during the operation which cause delay for the surgery that can lead to fatality. Therefore, this project aims to develop a multi-firing endoclip cartridge that can reduce the difficulty of reloading the endoclip system to its applicator by improving current design. Three design of multi-firing endoclip cartridges were produced by using different mechanism to apply the endoclip. The casing of the cartridge was designed in cylindrical shape with 40 mm diameter and 68 mm length with CATIA V5 software. These three designs formerly assessed by using decision matrix method for assortment of the best concept design. The result from the decision matrix table shows that design with revolve internal clip holder got the highest decision matrix selection amongst the three designs, advantaging in holding more clips and can reduce operation time compared to the other two designs
