System for assessment of colonoscope manipulation
A comprehensive system for objective assessment of colonoscope manipulation includes a handgrip for collecting and transmitting colonoscope handling data including force and motion data; a patient pain monitor for collecting and transmitting data on the level of patient's pain and discomfort; and digital processing means for extracting useful features such as colonoscope tip advancement speed from colonoscope-provided video images. All data is wirelessly transmitted to an electronic unit for processing and displaying on a monitor. A colonoscopy procedure is properly conducted when certain shaft advancement causes appropriate tip advancement, all without an increased level of patient's pain. The system of the invention is aimed at providing objective assessment data allowing for safer and less painful colonoscopies.
1. A system for assessment of colonoscope manipulation comprising:
a means for characterizing colonoscope shaft handling, said means adapted to collect and transmit colonoscope shaft handling data including forces applied to said colonoscope shaft and its movement resulting therefrom,
a colonoscope video monitor adapted for receiving, processing and displaying a colonoscope-provided video image,
a patient pain monitor adapted to collect and transmit data characterizing patient's pain and discomfort,
an electronic unit adapted to receive and process colonoscope shaft handling data and patient pain monitor data,
a digital image processing means adapted to extract image features from said video image and transmit them to said electronic unit, said digital image processing means is adapted to determine linear and rotational speed of a tip of said colonoscope from a series of progressive images supplied by said video monitor.
2. The system as in claim 1 , wherein said image features include at least one feature selected from a group of features consisting of sharpness, brightness and contrast distribution.
3. The system as in claim 1 , wherein said electronic unit is equipped with a display presenting received data in real time.
