Medical ophthalmic device
A tool comprising a handpiece having a flattened cannulated tip that is adapted to receive flow from a pumping unit, in order to generate a jet of fluid suitable for procedures such “hydro-dissecting” cells in the eye. According to an embodiment of the invention, the tool comprises a visualization probe with at least one camera, wherein the sensor of the at least one camera is distally located at the tip of the tool to be inserted in to the eye for imaging from within the eye.
1. A medical ophthalmic endoscopic device comprising at least one camera, wherein a sensor of the at least one camera is located at a distal end of said endoscopic device,
wherein said camera and one or more components/tools are integrated in the endoscopic device,
wherein the outer diameter of said endoscopic device is about 1.5 mm or less,
wherein the camera is located at a center of the distal end and the one or more components/tools are arranged around the camera, and
wherein the camera has a rectangular shape and the distal end has a circular shape,
the endoscopic device further comprising a handpiece and a flattened distal tip configured to receive fluid flow from a pumping unit and generate a jet of fluid suitable for hydro-dissecting cells in an eye of a subject, wherein the fluid flow is controllable by a control unit configured to allow variations in the fluid flow to the flattened distal tip.
2. The device of claim 1 , wherein the endoscopic device is configured to be inserted through an incision made around a cornea of an eye of a subject during a procedure of cataract surgery and/or Minimally Invasive Glaucoma Surgery (MIGS).
3. The device of claim 1 , wherein the endoscopic device is configured to be inserted through a trocar.
4. The device of claim 1 , wherein the one or more components comprise one or more illumination sources.
5. The device of claim 4 , wherein the one or more illumination sources comprise one or more LEDs, the one or more LEDs are located around the sensor.
6. The device of claim 4 , wherein the one or more illumination sources are located proximally in the device thus light reaches the distal end of the endoscopic device via one or more optic fibres and/or one or more light guides.
7. The device of claim 1 , comprising a camera located at a distal end of the endoscopic device, one or more illumination sources located proximally in the device and one or more optic fibres and/or one or more light guides providing light from the illumination source to the distal end of the device.
8. The device of claim 7 , wherein the one or more optic fibres and/or one or more light guides are arranged around the sensor at the distal end of the device.
9. The device of claim 1 , wherein the one or more components/tools comprise an irrigation channel.
10. The device of claim 9 , comprising a camera located at a distal end of the endoscopic device; one or more illumination sources located proximally in the device; one or more optic fibres and/or one or more light guides providing light from the illumination source to the distal end of the device; and one or more irrigation channels.
11. The device of claim 10 , wherein the one or more optic fibres and/or one or more light guides and the one or more irrigation channels are arranged around the sensor at the distal end of the device.
12. The device of claim 1 , wherein the one or more tools comprise a phaco-emulsifier tool and/or a tool for removing lens cells under direct vision.
13. The device of claim 12 , wherein the tool for removing lens cells comprises an irrigation tool, an aspiration tool, or a combination thereof.
14. The device of claim 13 , wherein the irrigation and aspiration tools are integrated together in concentric circles, one in an inner circle and one in an outer circle, or they are located adjacently.
15. The device of claim 1 , wherein the handpiece comprises a valve configured to block or release the fluid flow, thereby facilitating control of a flow rate.
16. The device of claim 1 , wherein the valve is further configured to facilitate continuous or pulsed fluid flow.
17. The device of claim 1 , wherein the flattened distal tip is replaceable to control the fluid flow rate, pressure, velocity and/or trajectory.
18. The device of claim 1 , wherein the flattened distal tip is straight, curved or bendable.
19. The device of claim 1 , wherein the flattened distal tip is divided to facilitate separate fluid flow and suction.
20. The device of claim 1 , wherein the flattened distal tip is rotatable.
21. The device of claim 1 , wherein the size of an opening of the flattened distal tip is between about 0.5 mm-1 mm.
