Claims (6)
- 脳室へシースを留置するための脳室穿刺用ダイレータ装置であって、脳室穿刺用チューブと、この穿刺用チューブに相対的にスライド可能に外挿された拡張用ダイレータと、このダイレータと穿刺用チューブを所定位置で固定可能な固定機構と、前記ダイレータに相対的にスライド可能に外挿されたシースとを具え、前記穿刺用チューブの前端部に前記ダイレータの前端と係合してダイレータが前記チューブの前端から突出しないようにする係合部が設けられていることを特徴とする脳室穿刺用ダイレータ装置。
- 請求項1に記載の脳室穿刺用ダイレータ装置において、係合部は、先が細く後端にいくにしたがい次第に径が大きくなり、ダイレータの前端と係合する後端がやや丸みをもった湾曲面に形成されていることを特徴とする脳室穿刺用ダイレータ装置。
- 請求項1又は2に記載の脳室穿刺用ダイレータ装置において、脳室穿刺用チューブに剛性を付与するためにスライド可能に内挿されたスタイレットを具えたことを特徴とする脳室穿刺用ダイレータ装置。
- 請求項1ないし3のいずれかに記載の脳室穿刺用ダイレータ装置において、ダイレータの前端側が徐々に径が小さくなる形状に形成されていることを特徴とする脳室穿刺用ダイレータ装置。
- 請求項3又は4に記載の脳室穿刺用ダイレータ装置において、スタイレットと穿刺用チューブを所定位置で固定可能な固定機構を具えたことを特徴とする脳室穿刺用ダイレータ装置。
- 請求項1ないし5のいずれかに記載の脳室穿刺用ダイレータ装置において、シースの後端部にはシースが過度に脳室に押し込まれるのを防ぐための脳表ストッパが設けられていることを特徴とする脳室穿刺用ダイレータ装置。
