Occlusion ring and method and device for its application

Claim 2

A ring applicator device for use in applying an elastic occluding ring to an anatomical tubular structure which comprises an inner cylinder slidable disposed within an outer cylinder, forceps means slidably disposed within said inner cylinder, said forceps means being spring loaded so that they spring open when they are displaced from the end of the inner cylinder, means for moving said forceps means into and out of the inner cylinder and means for ejecting an elastic ring from the end of said inner cylinder by axially displacing said outer and inner cylinders relative to each other.

Claim 3

The device of claim 1, wherein the inner cylinder is associated with a spring means such that in the loaded state the front end portion of the inner cylinder extends beyond the front end portion of the outer cylinder.

Claim 4

The device of claim 2, wherein means are provided for locking and unlocking the inner cylinder relative to the outer cylinder.

Claim 5

The device of claim 1, wherein the forceps means are slidably disposed within the inner cylinder.

Claim 6

The device of claim 4, wherein handle means are attached to the opposite end portion of the forceps means, said handle means being adapted to slide a fixed distance in the axial direction of the ring applicAtor to expose the forceps means from the end of the inner cylinder and retract said forceps means into the inner cylinder.

Claim 7

The device of claim 1, wherein an optical viewing means and an illuminating means are combined with the ring applicator.

Claim 8

The device of claim 6, wherein the optical viewing means and illuminating means is a laparoscope.

Claim 9

The device of claim 1, wherein a culdoscope is combined with the ring applicator, said culdoscope and ring applicator being in justaposition with respect to each other.

Claim 10

The device of claim 1, wherein the optical viewing means and illuminating means are recessed from the end portion of the inner cylinder so that the physician has full vision of said end portion and the extension and retraction of the forceps means therefrom.

Claim 11

A ring applicator device for use in applying an elastic occluding ring to an anatomical tubular structure which comprises an outer cylinder having a cut-away front portion and slidably disposed about an inner cylinder, said inner cylinder housing optical viewing means, illuminating means and a hollow cylinder, said hollow cylinder extending a distance in front of the optical viewing means and illuminating means and housing forceps means slidably disposed therein, said cut-away portion of the outer cylinder terminating in a ring pusher which is coaxially disposed about said hollow cylinder and slidably disposed with respect thereto, means for moving said forceps means into and out of the hollow cylinder, and means for removing an elastic ring from the end of the hollow cylinder by axially displacing said outer and hollow cylinders relative to each other.

Claim 12

A ring applicator device for use in applying an elastic occluding ring to an anatomical tubular structure which comprises an outer cylinder having a cut-away front portion and slidably disposed about an inner cylinder, said inner cylinder housing optical viewing means, illuminating means and a hollow cylinder, said hollow cylinder extending a distance in front of the optical viewing means and illuminating means and housing forceps means slidably disposed therein, said cut-away portion of the outer cylinder terminating in a ring pusher which is coaxially disposed about said hollow cylinder and slidably disposed with respect thereto, means for moving said forceps means into and out of the hollow cylinder, and means for removing an elastic ring from the end of the hollow cylinder by axially displacing said outer and hollow cylinders relative to each other.

Claim 13

The device of claim 10, wherein handle means are attached to the opposite end portion of the forceps means, said handle means being adapted to slide a fixed distance in the axial direction of the ring applicator to expose the forceps means from the end of the hollow cylinder and retract said forceps means into the hollow cylinder.

Claim 14

The device of claim 11, wherein the opposite, rear end portions of the optical viewing means is off-set with respect to the ring applicator.

Claim 15

The device of claim 10, wherein the outer and inner cylinders are provided with a spring locking device.

Claim 16

The device of claim 13, wherein the spring locking device is provided with a screw lock.

Claim 17

The device of claim 13, wherein the spring locking device is provided with a trigger means.

Claim 18

The ring applicator device of claim 1, wherein in the loaded state, the front end of the inner cylinder protrudes beyond the outer cylinder.
