Visiting Points with a Bevel-Tip Needle∗
Many surgical procedures could benefit from guiding a bevel-tip needle through a sequence of treatment points in a patient. For example, brachytherapy procedures implant radioactive seeds to treat cancer, and biopsy procedures extract tissue samples to test for cancer. A bevel-tip needle has an asymmetric tip that cuts through tissue along a circular arc. By rotating the needle during its inser...
متن کاملForce-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 کاملPreliminary evaluation of robotic needle distal tip repositioning
Advances in medical imaging now provide detailed images of solid tumors inside the body and miniaturized energy delivery systems enable tumor destruction through local heating powered by a thin electrode. We have developed a robot for accurately repositioning the distal tip of a medical instrument such an ablation probe to adjacent points within tissue. The position accuracy in ballistics gelat...
متن کاملAn unusual foreign body (sewing needle tip) in the tonsils.
Foreign bodies in the throat are common emergencies in ear nose and throat practice. Usual foreign bodies includes coin, bone piece, fish bone, nails, button, glass pieces, denture, ear ring, chain, pins and needles . There are very few reported cases of a foreign body in the tonsillar substance. Pharyngeal foreign bodies get lodged in the mucosa and may not be visible on routine ENT examinatio...
متن کاملVisiting a Sequence of Points with a Bevel-Tip Needle
Many surgical procedures could benefit from guiding a bevel-tip needle along circular arcs to multiple treatment points in a patient. At each treatment point, the needle can inject a radioactive pellet into a cancerous region or extract a tissue sample. Our main result is an algorithm to steer a bevel-tip needle through a sequence of treatment points in the plane while minimizing the number of ...
