Development of configuration differing master slave combined forceps

With small incision, patient is benefited in laparoscopic surgery. However, surgeon has to perform with less dexterity owing to the constraint by the incision. To enhance the operationally in this surgery, master slave forceps with three additional freedoms at the end of conventional forceps was developed. Master part and slave part are combined and different configuration was chosen for the master and slave. Developed forceps can be used like the conventional forceps and has three additional freedoms for better operationality. Description of developed forceps is shown in this paper.
