Abstract
A handgrip for a colonoscope shaft capable of measuring and presenting to the operator of radial and longitudinal forces applied by the operator during the manipulation with the colonoscope. The handgrip includes an internal sleeve positioned over the shaft of the colonoscope so that it can be released and repositioned by depressing a release button. And external sleeve covers the internal sleeve and provides for a convenient grip by the operator. The only means of transmission of force applied by the operator from the external sleeve to the internal sleeve is the engaging means such as a flexible rectangular bar or a set of engaging plates imbedded between the external sleeve and internal sleeve. The engaging means are equipped with a set of sensors such as strain gages positioned on all sides of the bar to measure the forces between the sleeves, which correspond to the forces applied by the operator to the shaft of the colonoscope. The measurements are then transmitted to an electronic unit for data processing and then further to a display system such as a personal computer.

18. A handgrip system for measuring of forces applied to a colonoscope incorporating a colonoscope shaft, said system comprising:
-
a handgrip comprising in turn an internal sleeve adapted to be placed over and temporarily engage with said colonoscope shaft, an external sleeve slidingly positioned about the internal sleeve, and an engaging means positioned between said internal and external sleeves, said engaging means further equipped with a sensor means to measure the forces applied between said external and said internal sleeves and provide a force data, an electronic unit for initial data processing, said electronic unit including a cable for transmission of said force data from said sensor means to said electronic unit, and a display for presentation of force data captured by said sensor means. - View Dependent Claims (19, 20)
