PROBLEM TO BE SOLVED: To provide a medical powder intracorporeal injection device with a novel structure which, when a medical powder such as an antiadhesive material is injected into a body along with an aseptically introduced pressure gas, can achieve a predefined injection state regardless of the injection direction even during endoscopic surgery, etc.SOLUTION: Provided is a medical powder intracorporeal injection device 10 for injecting a medical powder along with a pressure gas, the injection device being provided with a rotatable powder storage component 30 for storing the medical powder such that the medical powder is supplied from the powder storage component 30 to an injection passage 60 of the pressure gas by a centrifugal force due to the rotation of the powder storage component 30 so as to be injected along with the pressure gas.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】癒着防止材などの医療用粉体を無菌的に導入された圧力気体と共に体内へ噴射するに際して、例えば内視鏡手術等においても、噴射方向に拘らず所定の噴射状態を安定して実現することのできる、新規な構造を備えた医療用粉体の体内噴射装置を提供すること。【解決手段】医療用粉体を圧力気体とともに噴射する医療用粉体の体内噴射装置10において、医療用粉体を収容する粉体収容部材30が回転可能に設けられており、医療用粉体が粉体収容部材30の回転に伴う遠心力によって粉体収容部材30から圧力気体の噴射通路60へ供給されて圧力気体とともに噴射されるようにした。【選択図】図4
