Abstract

A surgical or diagnostic camera system is disclosed that has a disposable cap-like device that is structured for removal of adhesions while under direct visualization with the camera. The adhesion removal device may have an electrode on the tip that can be activated to enhance separation of tissues and may be configured to securely snap on to the housing of the camera system.

Claims

1. An adhesion removal device comprising:

an engagement surface for releasable attachment to a housing; and

a tip portion structured when attached to the housing to extend outwardly from a leading end of the housing, the tip portion having an edge for prying bound tissue of an adhesion apart under direct view of a camera.

2. The adhesion removal device recited in claim 1 having a first end and a second end, the tip portion being positioned on the first end of the removal device, and further comprising an electrode on the first end and an energy tether extending from the second end for operative connection to a source of energy.

3. The adhesion removal device of claim 2 having a channel along the perimeter thereof for carrying a wire for the transfer of energy from the energy tether to the electrode.

4. The adhesion removal device of claim 1 having engagement surfaces for releasable attachment to the camera.

5. The adhesion removal device of claim 4 wherein the engagement surfaces of the removal device comprise a pair of prongs for grasping the housing.

6. An adhesion removal system comprising:

a housing having a first end and at least one camera positioned on the first end; and

an adhesion removal device releasably mounted on the housing and having a tip portion that extends outwardly from the first end of the housing structured for prying bound tissue of an adhesion apart.

7. The adhesion removal system of claim 6 wherein the removal device has a first end and a second end, the tip portion being positioned on the first end of the removal device, and further comprising an electrode on the first end and an energy tether extending from the second end for operative connection to a source of energy.

8. The adhesion removal system of claim 7 wherein the removal device has a channel along the perimeter thereof for carrying a wire for the transfer of energy from the energy tether to the electrode.

9. The adhesion removal system of claim 6 wherein the removal device has engagement surfaces for releasable attachment to the housing.

10. The adhesion removal system of claim 9 wherein the engagement surfaces of the removal device comprise a pair of prongs for grasping the housing.

11. The adhesion removal system of claim 9 wherein the housing has engagement surfaces configured for releasable complementary engagement with the engagement surfaces of the removal device.

12. The adhesion removal system of claim 6 wherein the removal device is made of a transparent biocompatible nonmagnetic material.

13. The adhesion removal system of claim 6 wherein the removal device is made of a biocompatible material.

14. The adhesion removal system of claim 6 wherein the housing has one camera having a lens directed at an angle greater than 0 degrees and less than 90 degrees downwardly from the central axis of the camera relative to such axis.

15. The adhesion removal system of claim 14 wherein the housing has a second camera.

16. The adhesion removal system of claim 15 wherein the second camera has a lens directed along one of the central axis of the housing or an axis parallel to the central axis of the housing.

17. The adhesion removal system of claim 14 wherein the camera lens is directed at an angle between 10 and 45 degrees downwardly from the central axis relative to the central axis of the housing.

18. The adhesion removal system of claim 6 wherein the housing further comprises at least one light source adjacent to the at least one camera.

19. The adhesion removal system of claim 6 wherein the housing further comprises magnets mounted therein.

20. The adhesion removal system of claim 19 further comprising an external magnetic control unit for manipulating the movement of movement of the housing when deployed in use in a patient.
