Abstract

Claims (30)

1. An endoscope with a side-mountable single-use portion and a multiple-use portion, wherein:

the single-use portion includes:

a housing that has a distal end and a proximal end and has a proximal port at said proximal end and an intermediate port distal to the proximal port;

a cannula that extends distally from the distal end of the housing in an axial direction and has a distal port at a distal portion of the cannula;

a single lumen extending from said proximal port at the proximal end of the housing to the distal port at the distal portion of the cannula;

an imaging and illumination module at said distal portion of the cannula;

an electrical connector that is affixed to said housing and is operatively coupled with said imaging and illumination module; and

the multiple-use portion includes:

a handle with a top, lateral side, and an open outwardly facing slot at the lateral side, which slot is elongated in the axial direction; and

a display module mounted to the handle;

wherein

wherein one of said housing and said multiple-use portion includes at least one ridge and the other includes at least on slot, each of said at least one ridge and at least one slot are elongated in the axial direction, and said at least one ridge is configured to snap snugly but releasably into said at least one slot in a relative motion of the single-use portion and the reusable portion in a direction across the axial direction to thereby secure the single-use portion and the multiple-use portion to each other and thereby form said endoscope;

wherein the electrical connectors of the housing and the reusable portion are configured to mate and establish an electrical contact between the single-use portion and the reusable portion in relative motion of the single-use portion and the reusable portion along the axial direction following the motion across the axial direction;

wherein said electrical connectors when mated transmit power to said imaging and illumination module and transmit images therefrom to said display; and

wherein said display nodule has a touch-sensitive screen that is above the single-use portion; and

each of the proximal port, the intermediate port and the distal port connect to said single lumen.

2. The endoscope of claim 1 , in which said proximal port protrudes proximally from said handle.

3. The endoscope of claim 1 , in which said grooves and ridges extend to proximal ends of said housing and handle.

4. The endoscope of claim 1 , in which the handle includes a WiFi circuit configured to wirelessly transmit images taken with said imaging and illumination module.

5. The endoscope of claim 1 , in which said electrical connector in the reusable portion is configured for coupling to external equipment comprising one or more of monitors and/or workstations for sending thereto images taken with said imaging and illumination module.

6. The endoscope of claim 1 , in which said display module is mounted on said handle for selective tilting and/or rotation relative to the handle about one or more axes.

7. The endoscope of claim 1 , in which said proximal port is vertically in line with a center of said display module and less than 15 cm from a center of the display module, thereby placing the proximal port in a line and angle of sight of a viewer that includes both the display module and the proximal port.

8. An endoscopic multiple-use portion comprising:

a multiple-use handle with a top, a lateral side, and a pistol grip configured for grasping with a user's hand;

an open, outwardly facing slot at the lateral side of said handle, wherein said slot is above the pistol grip and extends along a longitudinal axis;

wherein said slot is open in a direction transverse to said longitudinal axis, has a groove or a ride, and is configured for removably snap-fitting therein an insert housing that a proximally facing electrical contact and a ridge or a groove configured to snap to the groove or ridge in the slot when inserted in the slot in a direction across to said longitudinal axis;

a distally facing electrical contact mounted on the handle and configured to make electrical contact with the proximally facing contact of the housing in a relative motion of the handle and the housing along said longitudinal axis subsequent to the motion acrtoss the longitudinal axis;

a display module with a screen to display images, mounted to an upper portion of said handle for rotation and/or pivoting relative to the handle; and

image processing circuits inside the handle, operatively coupled with said display module when said insert housing is snapped into said slot and configured to display images sent thereto from said imaging module.

9. The endoscopic apparatus of claim 8 , including a lumen that extends essentially straight in said insert housing and cannula along said longitudinal axis and has a distal port extending proximally from a proximal end of the insert housing.
