Abstract:
A surgical implement and a manipulation system including the surgical implement may include at least one instrument including at least one joint portion. The joint portion may include a first part, a second part connected to the first part, and a force applying element for applying a force for bending (or rotating) the second part. A distance between a joint point and a force application point where a force is applied may be greater than a diameter of at least one of the first part and the second part. The instrument may further include a second joint portion spaced apart from the joint portion, and a surgical tool connected to an end portion of the second joint portion. The manipulation system may include a supporting structure, at least one instrument supported by the supporting structure, and an operating device for operating the instrument.
