摘要：
PROBLEM TO BE SOLVED: To provide a spinous process spacer for widening and maintaining the space between spinous processes which has become narrow in a spinal canal stenosis patient.SOLUTION: The spinous process spacer includes: a first member having a first barrel section arranged in between both adjacent spinous processes and provided to be capable of supporting the upper spinous process, a first upper blade section extending upward from the first barrel section, a first lower blade section extending downward from the first barrel section and provided to be capable of supporting one side surface of the upper spinous process, and capable of supporting the other side surface of the lower spinous process, and an insertion section extending from the first barrel section to the side surface and a second member having a second barrel section having a fitting hole into which the insertion section is fitted, a second upper blade section extending upward from the second barrel section and provided to be capable of supporting the other side surface of the upper spinous process, and a second lower blade section extending downward from the second barrel section and provided to be capable of supporting the other side surface of the lower spinous process. The spinous process spacer has excellent biocompatibility since there is no possibility of damaging a ligament or a bone when operating on the spinal canal stenosis patient and is secure.COPYRIGHT: (C)2013,JPO&INPIT【課題】棘突起間スペーサを提供すること。【解決手段】隣り合う両棘突起間に配置されて上棘突起を支承可能に設けられる第1の胴部と、前記第1の胴部から上方に伸びて上棘突起の一方の側面を支持可能に設けられる第1の上羽根部と、前記第1の胴部から下方に伸びて下棘突起の一方の側面を支持可能に設けられる第1の下羽根部と、前記第1の胴部から側面に伸びた嵌入部と、を有する第1の部材と、前記嵌入部が嵌まり込む嵌入孔を有する第2の胴部と、前記第2の胴部から上方に伸びて上棘突起の他方の側面を支持可能に設けられる第2の上羽根部と、前記第2の胴部から下方に伸びて下棘突起の他方の側面を支持可能に設けられる第2の下羽根部と、を有する第2の部材と、を備える棘突起間スペーサ。本発明に係る棘突起間スペーサは、脊柱管狭窄症の患者への施術に際して靱帯や骨が損傷する虞がなく、堅固である他、人体への適合性に優れている。【選択図】図2
