Force-Sensor-Based Estimation of Needle Tip Deflection in Brachytherapy
A virtual sensor is developed for the online estimation of needle tip deflection during permanent interstitial brachytherapy needle insertion. Permanent interstitial brachytherapy is an effective, minimally invasive, and patient friendly cancer treatment procedure. The deflection of the needles used in the procedure, however, undermines the treatment efficiency and, therefore, needs to be minim...
متن کاملPrediction of needle deflection based on reaction force analysis for needle puncture robot with CT equipment
Abstract: There is a surgical method called Interventional Radiology (IR). This surgical method is conducted with imaging modality such as CT and X-rays. As compared with conventional survey, IR can be conducted in local anesthesia and this surgical method is minimally-invasive to patients. Recently IR is conducted by surgeons using a forceps and a needle. The minimum size of malignancy is appr...

متن کاملCharacterizing tissue stiffness at the tip of a rigid needle using an opto-mechanical force sensor
We present a novel device that allows the user to measure the Young Modulus of a material at the opening of a 5 mm diameter needle. The device relies on a miniaturized cantilever spring mounted at the end of the needle and interrogated via Fabry-Pérot optical fiber interferometry. The probe is repetitively brought in and out of contact with the sample at the end of the needle by means of a stee...
متن کاملEffects of Tip Geometry of Surgical Needles: an Assessment of Force and Deflection
Precise placement and steering of surgical needles is very important for many medical diagnostic and therapeutic procedures. But accurate steering and placement of needles in soft tissue is challenging because of a variety of reasons. In this study we focused on the effects of tip geometry (bevel tip, diamond tip, and conical tip) of brachytherapy needles while inserted in soft material phantom...
