PROBLEM TO BE SOLVED: To provide a surgical needle device for being used together with a replaceable lancet.SOLUTION: A surgical needle device comprises: a housing that accepts a replaceable lancet 34 introduced to the housing, when used; a driving mechanism 59 operable to instantly drive the lancet 34 so as to protrude a tip end thereof from the housing; and a nose part 14 having an opening that the lancet passes to protrude when being emitted. The nose part 14 is engaged with a front end part of the housing by a screw system such that an intrusion depth of the lancet 34 can be set in advance. The nose part 14 can be elastically deformed between a position where the nose part is locked so as not to rotate and a position where the nose part 14 can freely rotate.SELECTED DRAWING: Figure 4 |
