Abstract

A port device includes a tubular body sized to be inserted through a pair of ribs in a chest wall of a patient, a ball provided about the body, and a base defining a socket in which the ball is provided. Detent structure permits but limits longitudinal movement of the body relative to the ball. The base includes a clamping system which compresses the ball to lock the ball at a selected orientation within the socket and also immobilizes the port body relative to the ball. The distal end of the body includes a pair of swivels rotatably attached thereto. An obturator is extendable within the body maneuvers the swivels between a closed position (in which the swivels are oriented substantially parallel to the axis of the body), and an open position (in which the swivels are directed outward from the port).

Claims

1. A port assembly for insertion through a hole in a chest wall and for receiving medical instruments, comprising:

a) a port body having a proximal end and a distal end and defining an opening sized to receive a distal portion of a medical instrument therethrough;

b) a mechanical clamp including clamping elements adapted to be positioned about internal and external sides of a portion of the chest wall and apply compression to said portion;

c) a means for angling said port body relative to said clamp such that when said port body is in an angled position, said clamping elements of said clamp maintain compressing contact with the internal and external sides of the portion of the chest wall; and

d) a means for locking said port body relative to said clamp.

2. A port assembly according to claim 1, wherein:

said port body is longitudinally movable relative to said clamp.

3. A port assembly according to claim 1, wherein:

said clamp clamps exterior and interior portions of the chest wall.

4. A port assembly according to claim 1, wherein:

said clamp comprises swivels coupled to a distal portion of said port body and rotatable relative thereto and a base member.

5. A port assembly according to claim 1, wherein:

said means for angling includes a ball about said port body and a socket element.

6. A port assembly according to claim 5, wherein:

said port body is longitudinally movable relative to said ball.

7. A port assembly according to claim 5, further comprising:

e) detent means for limiting movement of said port body relative to said ball.

8. A port assembly according to claim 5, wherein:

said ball includes two oblate portions and a plurality of slits extending into each of said oblate portions.

9. A port assembly according to claim 8, wherein:

said means for clamping compresses said ball to substantially prevent movement of said port body relative to said ball.

10. A port assembly according to claim 1, further comprising:

e) means for coupling said port assembly to a medical instrument having a distal end extending through said port body.

11. A port assembly for insertion through a hole in a chest wall and for receiving medical instruments, comprising:

a) a port body having a proximal end and a distal end and defining an opening sized to receive a distal end of a medical instrument therethrough;

b) at least one swivel at or adjacent said distal end of said port body and rotatable relative to said port body;

c) a base longitudinally movable over a portion of said port body proximal of said at least one swivel, said port body and said base being angularly movable relative to each other such that when said port body is any angled position relative to said base, each of said at least one swivel is adapted to maintain contact with the chest wall; and

d) means for locking said base relative to said port body.

12. A port assembly according to claim 11, further comprising:

e) a ball element about said port body,

wherein said base includes a socket in which said ball element is rotatable.

13. A port assembly according to claim 11, further comprising:

e) a means for introducing said port body into the hole in the chest wall and rotating said at least one swivel.

14. A port assembly according to claim 11, wherein:

said at least one swivel is two swivels, and each said swivel comprises first and second elements which are coupled together to define a pivot axis, said first element including a hole aligned with said pivot axis and said second element including an outer axle aligned with said pivot axis and an inner elongate ear portion.

15. A port assembly for insertion through a hole in a chest wall and for receiving medical instruments, comprising:

a) a port body having a proximal end and a distal end and defining an opening sized to receive a distal portion of a medical instrument therethrough;

b) a clamping means for clamping interior and exterior sides of the chest wall;

c) a means for locking, wherein said port body is longitudinally movable relative to said clamping means and said means for locking locks said port body relative to said clamping means; and

d) detent means for limiting movement of said port body relative to said ball when said means for locking is in an unlocked state.

16. A port assembly for insertion through a hole in a chest wall and for receiving medical instruments, comprising:

a) a port body having a proximal end and a distal end and defining an opening sized to receive a distal end of a medical instrument therethrough; and

b) two swivels at or adjacent said distal end of said port body and rotatable relative to said port body, each said swivel comprising first and second elements which are coupled together to define a pivot axis, said first element including a hole aligned with said pivot axis and said second element including an outer axle aligned with said pivot axis and an.inner elongate ear portion.

17. A port assembly according to claim 16, wherein:

one of said first and second elements defines a channel curved along a radius of curvature, and the other of said first and second elements includes key portion curved along said radius of curvature and sized to fit within the channel.

18. A port assembly according to claim 17, wherein:

said first and second elements each include a bore, and a pin is inserted through said bores in said first and second elements.

19. A port assembly according to claim 16, wherein:

each said swivel is provided with an elastomeric sleeve over portions of said first and second elements.
