Abstract

There is provided herein, an endoscope comprising an elongated shaft terminating with a tip section wherein said tip section comprises a permanent section connected to the elongated shaft and a removable section securely connectable to the permanent section, wherein the removable section comprises at least one capture device and at least one light source.

Claims

1. An endoscope comprising an elongated shaft defined by a longitudinal axis, wherein the elongated shaft comprises:

a permanent section fixedly connected to the elongated shaft, wherein the permanent section extends cylindrically along the longitudinal axis, comprising;

a cylindrical recess that extends along the longitudinal axis;

a first connector positioned within said cylindrical recess; and

a hollow cylindrical elongated protrusion extending from a distal face of the permanent section;

a cylindrical removable section connectable to the permanent section, the removable section comprising;

a cylindrical channel into which the hollow cylindrical elongated section protrusion from the permanent section is configured to be slidably inserted, thereby securely connecting the cylindrical removable section to the permanent section;

an elongated section extending from a proximal face of the cylindrical removable section and having a second connector, wherein said second connector is configured to connect to the first connector positioned in the cylindrical recess;

at least one capture device positioned in the cylindrical removable section; and

at least one light source positioned in the cylindrical removable section;

wherein, upon attachment of the cylindrical removable section to the permanent section, a substantially cylindrical endoscope tip is formed;

a locking mechanism configured to form a connection between the permanent section and the cylindrical removable section; and

a button positioned in a recess located on a side of the permanent section or cylindrical removable section, wherein the button is configured to release the locking mechanism, wherein the locking mechanism is configured to only be released if a corresponding command is provided from a control on a display device and wherein said corresponding command is configured to cause an electrical or mechanical effect required for releasing the locking mechanism.

2. The endoscope of claim 1, wherein the cylindrical removable section comprises a distal face of the endoscope tip.

3. The endoscope of claim 1, wherein the at least one capture device within the cylindrical removable section comprises a front-facing camera.

4. The endoscope of claim 1, wherein the at least one capture device within the cylindrical removable section comprises a side-facing camera.

5. The endoscope of claim 1, wherein the at least one capture device within the cylindrical removable section comprises a front-facing camera and further comprising a side-facing camera positioned in the cylindrical removable section.

6. The endoscope of claim 1, wherein the permanent section comprises at least one capture device.

7. The endoscope of claim 6, wherein at least one capture device within the permanent section comprises at least one side-facing camera.

8. The endoscope of claim 1, wherein, when the cylindrical channel of the cylindrical removable section and the hollow cylindrical elongated section protrusion from the permanent section are mated, a working channel is formed, wherein said working channel is configured to receive a surgical tool.

9. The endoscope of claim 1, wherein the cylindrical removable section comprises a first optic fiber and a first lens, and the permanent section comprises a second optic fiber and a second lens, such that the first lens is aligned with the second lens so as to transfer light between the first optic fiber and the second optic fiber.

10. The endoscope of claim 1 further comprising a switch on the permanent section, wherein the endoscope is configured to only operate when the switch is pressed by the cylindrical removable section.

11. The endoscope of claim 10 wherein an indication of a status of the switch is displayed on a display device.

12. An endoscope comprising an elongated shaft defined by a longitudinal axis, wherein the elongated shaft comprises:

a permanent section fixedly connected to a distal end of the elongated shaft, wherein the permanent section is cylindrical and extends distally along the longitudinal axis;

a cylindrical removable section configured to connect to the permanent section, wherein, upon connection of the cylindrical removable section to the permanent section, a substantially cylindrical endoscope tip is formed; and

a button positioned in a recess located on a side of the permanent section or the cylindrical removable section, wherein the button is configured to release the connection between the cylindrical removable section and the permanent section, wherein the connection is only released if a corresponding command is provided from a control on a display device, and wherein the corresponding command is configured to cause an electrical or mechanical effect required for releasing the connection.

13. The endoscope of claim 12, wherein the permanent section comprises:

a cylindrical recess that extends along the longitudinal axis; and

a hollow cylindrical elongated protrusion emerging from a distal face of the permanent section.

14. The endoscope of claim 13, wherein the cylindrical removable section comprises a cylindrical channel into which the hollow cylindrical elongated section protrusion from the permanent section is configured to be slidably inserted, thereby securely connecting the cylindrical removable section to the permanent section.

15. The endoscope of claim 13, wherein the cylindrical removable section comprises an elongated section comprising a first connector, wherein a second connector is positioned within a recess in the permanent section, and wherein the first connector is configured to connect with the second connector when said cylindrical removable section is connected to the permanent section.

16. The endoscope of claim 12, wherein the cylindrical removable section comprises at least one capture device.

17. The endoscope of claim 16, wherein the at least one capture device within the removable section comprises at least one of a front-facing camera and a side-facing camera.

18. The endoscope of claim 12, wherein the cylindrical removable section comprises at least one light source.
