PROBLEM TO BE SOLVED: To provide a puncture device which allows reliable puncture of a body tissue to a prescribed depth, does not impose heavy burden on a patient, is high in safety for the patient, and is high in safety for a practitioner as well.SOLUTION: A puncture device 1 includes: a puncture needle 5 for puncturing body tissues 600, and having a non-sharp but round needlepoint 55 a longitudinal-shaped vaginal insertion member inserted into a vagina a guide member 3 having a distal end part 321 positioned in the direction in which the needlepoint 55 heads and a joint means for joining the vaginal insertion member and the guide member 3. The vaginal insertion member or the joint means is provided with a support portion for supporting the puncture needle 5 so that the needlepoint 55 can move in such a way as to approach the distal end part 321. Further, the distal end part 321 is provided with a regulation portion 8 for regulating movements of the puncture needle 5 before the needlepoint 55 is exposed on a body surface 700 when the puncture needle 5 moves from the inside to the outside of the body tissues 600 in a state where the vaginal insertion member is inserted in the vagina and the guide member 3 is put on the body surface 700.COPYRIGHT: (C)2014,JPO&INPIT【課題】生体組織を所定の深さに確実に穿刺することができるとともに、患者の負担が少なく、患者の安全性が高く、また術者の安全性も高い穿刺装置を提供すること。【解決手段】穿刺装置1は、生体組織600を穿刺する、丸みを帯びた非鋭利な針先55を有する穿刺針5と、膣内に挿入される長手形状の膣挿入部材と、針先55が向かう方向に位置する先端部321を有する案内部材3と、膣挿入部材と案内部材3とを連結する連結手段とを備えている。膣挿入部材または連結手段には、穿刺針5を針先55が先端部321に向かって接近するように移動可能に支持する支持部が設けられている。また、先端部321には、膣挿入部材を膣内に挿入し、案内部材3を体表面700に宛がった状態で、穿刺針5が生体組織600をその内側から外側に向かって移動した際、針先55が体表面700に露出する前に、穿刺針5の移動を規制する規制部8が設けられている。【選択図】図2
