Surgical sleeve and trocar |
摘要 |
A surgical sleeve includes a housing and inner and outer sleeves coupled to the housing. A modular expandable hinge member is coupled to the outer sleeve and defines a radially expandable member to prevent inadvertent withdrawal of the surgical sleeve from a body cavity. A trigger is carried by the housing to cause relative movement between the inner and outer sleeves and radial expansion of the expandable member. The housing is further provided with a transversely slidable reducer assembly having three outer diameter seals for sealing against the exterior of surgical instruments having a variety of outer diameters. A trocar is provided for use with the surgical sleeve that is modular in construction and includes a shaft member and a modular, tubular, metallic cutting portion. The cutting portion forms only a portion of the trocar spike and the length of the shaft member governs the overall length of the trocar.
