Method and apparatus for hysteroscopy and endometrial biopsy
Methods and devices are described for performing a combined hysteroscopy and endometrial sampling. Techniques for improving visual images include forward facing fluid ports for clearing tissue debris and LED positioning and design. Manufacturability is improved through separately formed tip and shaft pieces. User interface features are described including user-friendly handle-mounted buttons as well the use of an interactive integrated touch screen display. The handle and display can be mated to a docking station for storage and recharging batteries.
1. An endoscopic device, comprising:
an elongate cannula configured for insertion through a cervix into a uterus;
a camera assembly disposed adjacent a distal end of the elongate cannula for acquiring imagery of the uterus;
a fluid port adjacent the distal end of the elongate cannula and through which fluid can flow to move debris away from the camera assembly to enhance the imagery acquired by the camera assembly;
a handle disposed proximal to the elongate cannula;
a display screen mounted to the handle;
a memory configured to store instructions; and
a processor configured to execute the instructions to perform operations comprising:
processing the imagery acquired by the camera assembly to generate processed imagery of the uterus, and
initiating presentation of one or more graphical user interfaces (GUIs) on the display screen, the one or more GUIs presenting the processed imagery of the uterus and one or more menus for collecting patient information via one or more soft buttons provided by the one or more menus, the one or more GUIs presenting the processed imagery of the uterus as a live video feed on the display screen automatically upon receipt of the patient information via the one or more soft buttons as the camera assembly continues to acquire additional imagery of the uterus, such that the live video feed provides live viewing of the uterus from the additional imagery,

6. The endoscopic device of claim 1 , wherein the camera assembly is capable of scanning a machine-readable code for collecting the patient information to identify a patient such that the live video feed is presented on the display screen automatically upon receipt of the patient information via the machine-readable code.
7. The endoscopic device of claim 1 , wherein the one or more soft buttons provide a list of one or more patient ID strings.
8. The endoscopic device of claim 7 , wherein the live video feed is presented on the display screen automatically upon user selection of a patient ID string of the one or more patient ID strings.
9. The endoscopic device of claim 8 , wherein the operations further comprise initiating a replay of a portion of the live video feed.
10. The endoscopic device of claim 8 , wherein the operations further comprise initiating a capture of a portion for the live video feed.
11. The endoscopic device of claim 10 , wherein the one or more GUIs present a timer indicating a duration of the portion of the live video feed.
12. The endoscopic device of claim 8 , wherein the operations further comprise initiating a capture of a photo from the live video feed.
13. The endoscopic device of claim 1 , wherein the operations further comprise initiating a replay of the processed imagery.
14. The endoscopic device of claim 13 , wherein the one or more GUIs further present one or more thumbnail images representing all of the photos and videos captured in association with a patient identified by the patient information.
15. The endoscopic device of claim 14 , wherein the one or more thumbnail images respectively present file names.
16. The endoscopic device of claim 14 , wherein at least one thumbnail image is associated with a video.
17. The endoscopic device of claim 14 , wherein the one or more GUIs comprise a video playback screen that is presented upon user selection of a thumbnail image of the one or more thumbnail images that represents a video.
18. The endoscopic device of claim 14 , wherein the one or more GUIs comprise a still image screen that is presented upon user selection of a thumbnail image of the one or more thumbnail images that represents a photo.
19. The endoscopic device of claim 1 , wherein the one or more GUIs present a setup menu comprising a plurality of device setting options.
20. The endoscopic device of claim 19 , wherein the plurality of device setting options comprises a system clock setting, a TV out formatting, and a memory card setting.
21. The endoscopic device of claim 1 , wherein the one or more GUIs present a return option for returning from a currently displayed GUI to a previously displayed GUI.
22. The endoscopic device of claim 1 , wherein the one or more GUIs comprises a home screen that provides a plurality of menu options, the plurality of menu options comprising a new patient option, a viewing option, and a replay option.
23. The endoscopic device of claim 1 , wherein the display screen is a touchscreen, and the one or more GUIs present a plurality of user selectable button images.
24. The endoscopic device of claim 1 , wherein the handle comprises a plurality of tactile elements in electrical communication with the camera assembly and by which a user can control the camera assembly to acquire the imagery of the uterus.
25. The endoscopic device of claim 1 , further comprising an electrical connector configured to relay electrical signals from the camera assembly to the display screen.
26. The endoscopic device of claim 25 , further comprising an electrical cable that extends from the camera assembly to the electrical connector.
27. The endoscopic device of claim 1 , further comprising a single-use portion that includes the elongate cannula and the camera assembly.
