Laparoscopy background l.jpg

Laparoscopy Background

  • Minimally invasive abdominal surgery

  • Multiple ports for tools – separate one for laparoscope

Current Laparoscopic Process

Trocascope XC2000 ver. 2.0

  • Eliminate one port by incorporating the camera onto the tool port

  • More convenient for surgical team - fewer hands required and viewable screen

  • Less traumatic for patient


Project goals and objectives l.jpg

Project Goals and Objectives

  • Combine current laparoscope with current surgical instrument to eliminate one port

  • Minimize camera module size, while maintaining speed and resolution

  • High resolution image displayed on LCD panel

  • Minimal wires – hopefully completely wireless and battery powered

  • Incorporate data storage device for later viewing


Low objectives l.jpg

Low Objectives

  • 10 mm max diameter for camera module

  • 640x480 resolution

  • 30 fps

  • LCD screen

  • LED lighting with imager

  • All wired connections

  • AC power


Mid level objectives l.jpg

Mid Level Objectives

  • Battery powered – supplement with AC (2-2.5 hr run time)

  • 6 mm max diameter of camera module

  • Higher resolution

  • Wireless

  • Stream video data to external monitor

  • Screen shot capability

  • SD onboard storage

  • Enable touch screen features


High level objectives l.jpg

High Level Objectives

  • Multi-camera interface – split screen

  • Motorized camera module

  • Time display

  • Audio features

  • Wireless transmission to external monitor

  • Foot pedal

  • 4 mm maximum diameter of camera module

  • Wireless storage to external device

32bit AVR


Camera l.jpg

Microcontroller w/ISI and LCD controller

Camera

(0V7690)

Camera

  • Connected via SCCB (I2C) and 8 parallel data lines

  • Camera takes 640x480 @ 30fps and sends it to the Image sensor interface on the microcontroller.

  • Microcontroller controls imager via SCCB connection.


Led s l.jpg

Microcontroller w/ISI and LCD controller

LED(s)

LED(s)

  • Connected via GPIO, possibly buffered with MOSFET or BJT to supply additional power

  • Each LED is connected through a buffer to a general I/O pin on the Microcontroller.

    • Allows touch screen to control LED through microcontroller, ideal for saving power and adjustable brightness.

  • LED will be selected for maximum efficiency and brightness. Don’t want to burn patient and want lots of illumination.


Slide12 l.jpg

Microcontroller w/ISI and LCD controller

VGA LCD Display

LCD

  • Connected via Microcontroller LCD interface.

  • Microcontroller takes data from imager and displays it on the LCD in VGA format.

  • Microcontroller takes button presses from LCD and performs desired operations, ie toggling LEDs, screenshots, etc

  • Utilizes RGB parallel input with 18 bits of color

  • VGA standards (480x640 @ 30 fps)


External storage l.jpg

Microcontroller w/ISI and LCD controller

SD Card

External Storage

  • SD Card viable option for video storage and retrieval

  • Uses standard SPI interface to communicate

  • Uses FAT32 storage system

  • SD interface built into processor

  • Easy to find documentation on SD interface

Risks concerns cont d l.jpg

Risks/Concerns Cont’d

  • Schedule Uncertainty

    • Enough time to learn how to store data, battery operable, etc.

    • Prototype completed by the beginning of March?

  • Component Risks

    • Expensive Eval. Board

    • Sensor frame rate and resolution vs. size

  • Questionable Feasibility

    • Low level objectives seem obtainable

    • Can we make our mid/high level objectives?


Market l.jpg

Market

  • Over 2 million laparoscopic surgeries performed each year

  • New laparoscopic surgeries are being introduced as technology improves

  • 6 million Trocar used each year


Laparoscopic surgery l.jpg

Laparoscopic Surgery

  • Patient’s Point of View

    • Cheaper

      • $1,000 less than open surgery

    • Quicker Recovery

      • Hospital stay is 1/4th the time of open surgery

    • Post operative pain is less

    • Reduced infection rate


Laparoscopic surgery23 l.jpg

Laparoscopic Surgery

  • Surgeon’s Point of View

    • Longer operative times
