Endoscopic elevator apparatus
View Patent ↗An endoscopic elevator apparatus cooperable with an insertion tube extending to a distal tip and having enhanced grasping and reduced scraping of an elongate medical device is disclosed. The apparatus comprises an elevator movably attached to the distal tip. The elevator has an inner side formed thereon defining a grasping slot for engagement with the endoscope. The elevator has a surface projection disposed thereon for inhibiting damage to the elongate medical device.
1. An endoscopic elevator apparatus cooperable with an insertion tube extending to a distal tip and having enhanced grasping and reduced scraping of an elongate medical device, the apparatus comprising:
an elevator movably attached to the distal tip, the elevator having an inner side formed thereon defining a grasping slot for engagement with the elongated medical device, the elevator having a surface projection disposed thereon for inhibiting damage to the elongate medical device: and
a grasping cover disposed directly on and adhered to the elevator, wherein the grasping cover includes a body having an open lip defining an opening within which the elevator is received, the surface projection being disposed on the grasping cover.
2. The apparatus of claim 1 wherein the surface projection is disposed on the inner side of the elevator.
3. The apparatus of claim 1 wherein the surface projection is a plurality of surface projections formed on the inner side of the elevator.
4. The apparatus of claim 1 wherein the surface projection is formed laterally across the inner side of the elevator.
5. The apparatus of claim 1 wherein the surface projection is formed longitudinally across the inner side of the elevator.
6. The apparatus of claim 1 wherein the grasping cover comprises a plurality of ridges.
7. The apparatus of claim 6 wherein the each ridge is formed laterally across the body relative to the elevator.
8. The apparatus of claim 1 wherein the inner side of the elevator comprises an edge adjacent to the grasping slot, and further wherein the surface projection is configured so that the surface projection inhibits contact between the elongate medical device and the edge.
9. The apparatus of claim 1 wherein the surface projection projects into the grasping slot and is configured to inhibit damage to the elongate medical device.
10. An endoscopic system for reduced scraping of an elongate medical device, the system comprising:
an insertion tube extending to a distal tip including an elevator movably attached to the distal tip, the elevator having an inner side formed thereon defining a grasping slot for engagement with the elongate medical device, the elevator having a surface projection disposed thereon for inhibiting damage to the elongate medical device, the insertion tube further including a grasping cover disposed directly on and adhered to the elevator,
wherein the grasping cover includes a body having an open lip defining an opening within which the elevator is received, and further wherein the at least one surface projection is disposed on the grasping cover.
11. The system of claim 10 wherein the surface projection is disposed on the inner side of the elevator.
12. The system of claim 10 wherein the surface projection is a plurality of surface projections formed on the inner side of the elevator.
13. The system of claim 10 wherein the surface projection is formed laterally across the inner side of the elevator.
14. The system of claim 10 wherein the surface projection is formed longitudinally across the inner side.
15. The system of claim 10 wherein the grasping cover comprises a plurality of ridges.
16. The system of claim 15 wherein the each ridge is formed laterally across the body relative to the elevator.
