    摘要: A surgical access port for insertion into a body cavity can have an elongate tubular body extending along an axis between a proximal end and a distal end, and a tip at the distal end of the tubular body for penetrating through a body wall and into the body cavity. The distal tip moves from a first, penetrating position to a second, retaining position when the body wall has been traversed. The surgical access port may further comprise a seal housing connected to the proximal end of the tubular body, the seal housing having an access port providing an opening into the tubular body to allow passage of surgical instruments. The distal tip may be sharp, pointed or bladed. The distal tip may also be substantially blunt or have a conical surface. The access port may further comprise a retention member for connecting the tubular body and the distal tip.
