Abstract

An endoscopic inspection closure is described which has a guide device preventing the puncture incision created by a trocar obturator and cannula from closing and a closure device which fits within the guide device. The closure device is removable after the initial endoscopic operation, for observation of healing and introduction of endoscopic surgical instruments.

Claims

1. Endoscopic closure inspection device comprising:

a guide device for long term placement into the body, said guide device comprising a sleeve having an internal diameter and a length with a flange at its proximal end and a cylindrical guide rod emplaceable into said sleeve, said guide rod having an outer diameter less than the internal diameter of said sleeve and a length longer than the length of said sleeve;

said guiding device inserted into a puncture site in the body and said guiding device preventing said puncture site from healing; and

a closure device which is insertable into said sleeve.

2. Endoscopic inspection device according to claim 1 characterized in that the sleeve is made from plastic.

3. Endoscopic inspection device according to claim 1 characterized in that the flange is provided with spaced apart openings.

4. Endoscopic inspection device according to claim 2, characterized in that the flange has a patient facing underside with a double-sided adhesive tape on said underside.

5. Endoscopic inspection device according to claim 1 characterized in that a germ barrier is arranged at the flange.

6. Endoscopic inspection device according to claim 5 characterized in that the germ barrier is a sealing ring on the side of the flange facing away from the sleeve.

7. Endoscopic inspection device according to claim 1 characterized in that an aperture is provided in the flange in the area of the sleeve and is covered with a material which seals itself after being pierced.

8. Endoscopic inspection device according to claim 1 characterized in that the closure device has a stopper provided with a flange which abuts the flange of the guide device when said closure device is inserted into said sleeve.

9. Endoscopic inspection device according to claim 8 characterized in that the stopper projects slightly beyond the distal end of the sleeve.

10. Endoscopic inspection device according to claim 9 characterized in that the stopper consists of plastic material.

11. Endoscopic closure inspection device comprising:

a guide device for long term placement into the body, said guide device comprising a sleeve having an internal diameter and a length with a flange at its proximal end;

said guiding device inserted into a puncture site in the body and said guiding device preventing said puncture site from healing; and

a closure device which is insertable into said sleeve closure device having, on the side of the flange facing the guide device, an envelope closed by the flange, said envelope made from expandable material.

12. Endoscopic inspection device according to claim 11 characterized in that the envelope can be extended beyond the distal end of the sleeve.
