FORCE SENSOR AND METHOD FOR DETECTING AT LEAST ONE FORCE COMPONENT

摘要

Disclosed is a force sensor for detecting a force component, especially a force component of a force (F) acting in the longitudinal direction of an elongate device, particularly a medical device such as a catheter or guide wire. The inventive force sensor encompasses a force transducer for the force that is to be detected, which consists of a base body with a front surface, at least one voltage- and/or expansion-sensitive resistance and a connection for mounting the sensor to the elongate device. The base body comprises at least one groove that causes an asymmetry of the base body relative to the the longitudinal direction of the elongate device, which causes the base body to bend when the force is applied from the axial direction. The front surface has a surface area which is substantially greater than the cross-sectional area of the base body in the region of the groove, but not substantially smaller than the cross-section of the remaining base body. The electrical connecting areas or trenches are mounted in a non-vertically manner to the axial direction of the elongate device.
