Retractable safety penetrating instrument for portal sleeve introduction |
摘要 |
A retractable safety penetrating instrument for introducing a portal sleeve into a cavity in the body includes a portal sleeve and a penetrating member disposed within the portal sleeve and supported in a manner to automatically move proximally from an extended position wherein a sharp distal end of the penetrating member protrudes from the portal sleeve to a retracted position wherein the sharp distal end of the penetrating member is protected in response to distal movement of the retractable safety penetrating instrument upon penetration into a cavity in the body. A retracting mechanism moves the penetrating member proximally and is normally locked in a position preventing proximal movement of the penetrating member and is released by distal movement of an operating member to trigger retraction of the penetrating member.
