Abstract
Various devices are provided for allowing multiple surgical instruments to be inserted through a single surgical access device at variable angles of insertion, allowing for ease of manipulation within a patient's body while maintaining insufflation. Safety shields and release mechanisms are also provided for use with various surgical access devices.
Claims20
A surgical method, comprising:
- positioning a retractor in tissue to form a pathway through the tissue;
- moving in a proximal direction a select one of a plurality of sealing elements in a substantially rigid housing relative to the housing, the retractor, and each of the other sealing elements, wherein the retractor extends distally from the housing, and each of the sealing elements is configured to receive a surgical instrument therein and form a seal around the surgical instrument;
- either before or after moving the one of the plurality of the sealing elements in the proximal direction, moving in a distal direction the one of the plurality of sealing elements relative to the housing, the retractor, and each of the other sealing elements;
- and
- either before or after moving the one of the plurality of the sealing elements in the distal direction, and either before or after moving the one of the plurality of the sealing elements in the proximal direction, angularly orienting the one of the plurality of sealing elements relative to the housing, the retractor, and each of the other sealing elements.
2 more elements
A surgical method, comprising:
- positioning a cannula in a body of a patient, the cannula extending distally from a housing with a single port therein;
- advancing a surgical instrument through the single port of the housing and then into a passageway extending through the cannula, the housing including a sealing element that forms a seal around the surgical instrument;
- and
- rotating an annular disc having the sealing element seated therein such that the annular disc, the sealing element, and the surgical instrument rotate relative to the housing, the annular disc having a first o-ring disposed on a top surface thereof, the annular disc having a second o-ring disposed on a bottom surface thereof, and the first and second o-rings forming a seal between the annular disc and the housing.
1 more element
A surgical device, comprising:
- a housing including a seal base that has a plurality of sealing ports formed therein, each of the sealing ports having a sealing element disposed therein that is configured to form a seal around a surgical instrument inserted therethrough;
- and
- an adapter associated with one of the sealing ports, the adapter being configured to move between a first position, in which the adapter is attached to the housing and the one of the sealing ports has a first effective diameter through which a surgical instrument is insertable, and a second position, in which the adapter is attached to the housing at a hinge and the one of the sealing ports has a second effective diameter through which a surgical instrument is insertable, the second effective diameter being less than the first effective diameter.
