<p>Provided is a surgical instrument, wherein the pressure-opposing force and the flexibility of the spring part can be easily adjusted and manipulability improved. The surgical instrument (10) is provided with: a functional part (11) that performs grasping, cutting, etc. of the object; an operating part (13) that allows the user to operate the functional part (11) by applying force; and a spring (14) that is configured from a pair of elastic strip-shaped parts and impels the operating part (13) to open the functional part (11). Forming multiple grooves (14A) in the strip-shaped parts of the spring (14) causes changes in the pressure-opposing force and the bending characteristics of the spring part (14) and allows adjustment of the manipulability of the functional part (11).</p> |
