Die Forming of Medical Forceps
Medical examinations and treatments using endoscopes are becoming increasing common due to their minimally invasive nature. Many types of medical devices for endoscopic therapy are available, and of these, forceps are most frequently used. Forceps prices are on the whole high, and one of the reasons for this can be attributed to the manufacturing method. Currently forceps parts are made by cutting or metal removal process. By replacing these methods with die forming, stable supply at low costs should be possible. This paper describes a study proposing and developing a forceps manufacturing method by die forming, and describes the successful results. It also reports the evaluation carried out on functions of the prototyped forceps and the proposed method of changing the shape of products for which die forming is not suitable.
