ForceSensingNeedle

1.  Vision for Force Sensing Needle

During the insertion and manipulation of minimally invasive tools, a physician’s ability to accurately feel forces on the tool is compromised as it transverses tissues of varying properties. It is valuable to know, for example, when specific membranes are punctured, or if there is a fatty deposit occluding the tool’s trajectory. These informations are important to make decisions for driving needle and perform a needle intervention. So we aims to provide interventional surgeons with the haptic cues for forces at the tip of a biopsy needle.

2.  Design

The function of this needle is similar to the MRI-compatible 3D shape sensing needle. Fiber Bragg gratings (FBG) sensors are used for strain sensing along the needle. Enhanced features and FBG sensors at the tip of the needle allow for resolution of contact loads at the needle tip. Deformations due to the axial loading were smaller than the deform caused by radial forces so we modified the needle tip design (adding multiple oval shape holes) to improve axial sensitivity. FEA result shows that ratio between axial and radial sensitivity before the modification the was 1:30 but after it became 1:4.
