|1. (WO2018162206) INTEGRATED MEDICAL INSTRUMENT FOR MEASURING FORCES IN THE DISTAL REGION OF A ROD AND PRODUCTION METHOD THEREFOR|
|Applicants:||TECHNISCHE UNIVERSITÄT DARMSTADT
|Title:||INTEGRATED MEDICAL INSTRUMENT FOR MEASURING FORCES IN THE DISTAL REGION OF A ROD AND PRODUCTION METHOD THEREFOR|
The invention relates to an integrated medical instrument for measuring forces in the distal region of a rod and to a manufacturing method therefor. The rod-shaped medical instrument according to the invention has a guide rod and at least one force sensor, which serves to measure forces in a distal region. In a preferred embodiment, the medical instrument is placed by means of a hollow needle, wherein the guide rod is guided through the interior of the hollow needle in order to guide a tip of the guide rod to the distal hollow needle section and beyond. The guide has a hole and a primary cable channel, wherein a substantially planar application surface, which is elastic, is formed on at least one inner side of the hole or of the cavity, wherein at least one force sensor is arranged on the at least one application surface of the guide rod in order to represent forces on the tip, by bending the application surface, wherein the force sensor is arranged in a protected manner, and wherein a conductor of the at least one force sensor is led through the primary cable channel from the inside.
