Design and Fabrication of an Industrial Thread Tension-testing Machine which provides a Quality-testing Solution to manufacturer of Suturing Needle Holder

Abstract

Biomedical devices are manufactured just like other products except for they are required to undergo strict quality tests to qualify stringent standards. Sialkot is manufacturing hub of biomedical devices, where most of the products are designed for both domestic and international markets. Dr Frigz International (Pvt) Ltd manufactures a brand of Needle Holders used in operation theatres for manual suturing. The device is manufactured through conventional processes and machining techniques. But through last few stages, the dimensional accuracy and functional quality is given great consideration. One such test is the ability of the Needle Holder to effectively hold suturing thread when given tension. This specific test is conventionally performed by hand, and therefore lot to lot inconsistencies are imminent. The aim of this project-based thesis is to design and fabricate an automation system which would not only speed up the quality-testing process but also ensure consistent test parameters for pass/fail labelling of Needle Holders.
