摘要：
Methods and devices are provided for providing access through tissue to a surgical site. Generally, the methods and devices allow adjustment of a surgical access ports longitudinal length. In one embodiment, a surgical access port is provided that includes a housing having a cannula distally extending therefrom. The housing can be configured to cut a proximal portion of the cannula to adjust a longitudinal length of the cannula and hence of the surgical access port. In another embodiment, a surgical access port is provided that includes a cannula formed of a plurality of modular segments removably coupled together. One or more of the segments can be configured to be removable from the cannula to change the cannulas longitudinal length.
