Abstract

Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient'"'"'s body while maintaining insufflation.

Claims

1. A surgical device, comprising:

a surgical access device having an inner pathway extending between proximal and distal ends thereof, and the access device including;

first and second sealing elements each configured to form a seal around a surgical instrument inserted therethrough and extending through the inner pathway,

a first pathway extending circumferentially around the access device and having disposed therein a first compressible member configured to laterally bunch in response to movement of the first sealing element within the first pathway relative to the second sealing element, and

a second pathway extending circumferentially around the access device having disposed therein a second compressible member configured to laterally bunch in response to movement of the second sealing element within the second pathway relative to the first sealing element and the first compressible member, wherein the first and second compressible members each include a bellows.

2. The device of claim 1, wherein the access device includes a base member at the proximal end, the base member having the first and second compressible members disposed therein.

3. The device of claim 1, wherein each of the rotatable members are in a vertical stack with the retractor being vertically below the rotatable members.

4. A surgical device, comprising:

surgical access device having an inner pathway extending between proximal and distal ends thereof, and the access device including;

first and second sealing elements each configured to form a seal around a surgical instrument inserted therethrough and extending through the inner pathway,

a first pathway extending circumferentially around the access device and having disposed therein a first compressible member configured to laterally bunch in response to movement of the first sealing element within the first pathway relative to the second sealing element, and

a second pathway extending circumferentially around the access device having disposed therein a second compressible member configured to laterally bunch in response to movement of the second sealing element within the second pathway relative to the first sealing element and the first compressible member, wherein the first sealing element is configured to move 360°

around the access device in the first pathway, and the second sealing element is configured to move 360°

around the access device in the second pathway.

5. The device of claim 4, wherein the first and second compressible members each include a bellows.

6. The device of claim 4, wherein the access device includes a base member at the proximal end, the base member having the first and second compressible members disposed therein.

7. A surgical device, comprising:

a flexible retractor configured to be positioned in tissue and having a pathway extending therethrough;

a rotatable member configured to rotate relative to the retractor, the rotatable member having a sealing element coupled thereto that rotates therewith, the sealing element being configured to receive a surgical instrument therethrough to pass into the pathway, and the sealing element being configured to form a seal around the surgical instrument;

a locking mechanism configured to lock the rotatable member in rotated position relative to the retractor and thereby lock the sealing element in rotated position relative to the retractor;

a second rotatable member configured to rotate relative to the retractor, the second rotatable member having a second sealing element coupled thereto that rotates therewith, the second sealing element being configured to receive a second surgical instrument therethrough and into the pathway, and the second sealing element being configured to form a seal around the second surgical instrument; and

a second locking mechanism configured to lock the second rotatable member in rotated position relative to the retractor and thereby lock the second sealing element in rotated position relative to the retractor;

wherein the rotatable member and the second rotatable member are in a vertical stack with one of the rotatable member and the second rotatable member being vertically below the other, and with the retractor being vertically below the rotatable member and the second rotatable member.

8. The device of claim 7, further comprising a base member having a track formed therein, the locking mechanism being configured to move between an unlocked position, in which the locking mechanism is configured to slide within the track and allow the rotatable member to rotate relative to the retractor, and a locked position, in which the locking mechanism is prevented from sliding within the track and prevents the rotatable member from rotating relative to the retractor.

9. The device of claim 7, wherein the rotatable member includes a ring.

10. The device of claim 7, further comprising a base member having first and second tracks formed therein, wherein:

the locking mechanism is configured to move between an unlocked position, in which the locking mechanism is configured to slide within the first track and allow the rotatable member to rotate relative to the retractor, and a locked position, in which the locking mechanism is prevented from sliding within the first track and prevents the rotatable member from rotating relative to the retractor, and

the second locking mechanism is configured to move between an unlocked position, in which the second locking mechanism is configured to slide within the second track and allow the second rotatable member to rotate relative to the retractor, and a locked position, in which the second locking mechanism is prevented from sliding within the second track and prevents the second rotatable member from rotating relative to the retractor.
