Access portal including sponge
摘要:
A surgical access portal includes a seal housing and a sleeve mounted to the sleeve housing having an internal longitudinal passage adapted to provide access to underlying tissue. A seal is in mechanical cooperation with an inner wall of the seal housing and has an opening for reception and passage of a surgical instrument in a substantially sealed relation. A sponge is disposed distally of the seal and absorbs fluids that enter the seal housing.
