PROBLEM TO BE SOLVED: To make a surgical handpiece easy to be gripped.SOLUTION: A surgical handpiece comprises: a suction flow passage member for suctioning liquid a suction force adjustment mechanism comprising a hole communicating with the suction flow passage member and a housing having the suction flow passage member and the suction force adjustment mechanism. The housing is provided with the suction force adjustment mechanism on an upper surface side, and comprises: a grip section gripped by a user and a bent portion being positioned at a leading end side of the grip section and bent obliquely downward with respect to the grip section. At least a part of the grip section is positioned closer to the leading end side of the housing and closer to a lower surface side of the housing than a center of the suction force adjustment mechanism in a longitudinal direction of the housing, and the grip section comprises an inclined portion inclined to the upper surface side as it goes toward the leading end side.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】手術用ハンドピースを把持し易くすること。【解決手段】液体を吸引するための吸引流路部材と、前記吸引流路部材に通じる孔を備える吸引力調整機構と、前記吸引流路部材および前記吸引力調整機構を有する筐体と、を備え、前記筐体は、上面側に前記吸引力調整機構が設けられ、ユーザーによって把持される把持部と、前記把持部の先端側に位置し、前記把持部に対して斜め下向きに屈曲する屈曲部と、を備え、前記把持部は、少なくとも一部が前記筐体の長手方向についての前記吸引力調整機構の中心よりも前記筐体の先端側、且つ前記筐体の下面側に位置し、前記先端側に向かうに連れて上面側に傾斜する傾斜部を備える手術用ハンドピース。【選択図】図5
