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, having a distal section, wherein said distal section comprises;

a permanent section fixedly connected to the elongated shaft and comprising a first semi-cylindrical portion that extends along said longitudinal axis and a second semi-cylindrical portion that extends along said longitudinal axis, wherein said first semi-cylindrical portion is longer than said second semi-cylindrical portion, at least one recess in said first semi-cylindrical portion, a cylindrical recess in the second semi-cylindrical portion, at least one working channel positioned between a top surface of the first semi-cylindrical portion of said permanent section and said recess;

a semi-cylindrical removable section comprising at least one protrusion adapted to be slidably inserted into the recess in the first semi-cylindrical portion and a cylindrical protrusion adapted to be slidably inserted into said cylindrical recess, thereby securely connecting the removable section to both the first semi-cylindrical portion and the second semi-cylindrical portion of the permanent section, wherein the removable section comprises at least one capture device and at least one light source and wherein, upon attachment of the 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 semi-cylindrical removable section;

a button positioned in a recess located on a side of the permanent section or semi-cylindrical removable section, wherein the button is configured to release the connection, wherein the connection 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 connection.

2. The endoscope according to claim 1, wherein said at least one capture device within the removable section comprises a front-facing camera.

3. The endoscope according to claim 1, wherein said at least one capture device within the removable section comprises a side-facing camera.

4. The endoscope according to claim 1, wherein said at least one capture device within the removable section comprises a front-facing camera and a side-facing camera.

5. The endoscope according to claim 1, wherein said permanent section comprises at least one capture device.

6. The endoscope according to claim 5, wherein at least one capture device within the permanent section comprises a side-facing camera.

7. The endoscope according to claim 1, wherein the substantially cylindrical endoscope tip comprises a distal face, and wherein the permanent section forms a part of the distal face and the removable section forms another part of the distal face.

8. The endoscope according to claim 1, wherein said removable section further comprises a hollow elongated section protruding from the removable section and the permanent section comprises a channel configured to mate with said hollow elongated section, so as to provide a working channel configured for insertion of a surgical tool.

9. The endoscope according to claim 1, wherein said cylindrical recess in the second semi-cylindrical portion and cylindrical protrusion in the removable section form an elongated section configured to pass a cable for electric or data signals, the elongated section ending with a first connector.

10. The endoscope according to claim 1, wherein said removable section comprises a first optic fiber and a first lens, and said permanent section comprises a second optic fiber and a second lens, such that the first lens corresponds to the second lens so as to transfer light between the first optic fiber and the second optic fiber.

11. The endoscope according to claim 1, further comprising a switch on the permanent section such that the endoscope can operate only if the switch is pressed by the removable section.

12. The endoscope according to claim 11, wherein an indication of a status of the switch is displayed on said display device.
