A SIMPLIFIED PERITONEUM-GRASPING FORCEPS

Endoscopic resection of a large pedunculated duodenal polyp using a grasping type scissors forceps.

tally discovered during screening esopha− gogastroduodenoscopy in a 72−year−old woman. The polyp, located in the second portion of the duodenum, had a long stalk and a large head. Its removal was consid− ered to be technically demanding be− cause the head of the polyp occluded the lumen of the duodenum, making it diffi− cult to maneuver the snare over the polyp. The stalk part of the polyp, how...

Ultrasound-guided retrieval of lost intrauterine devices using very fine grasping forceps: a case series.

AIM To assess the efficacy of a novel ultrasound-guided procedure for the retrieval of intrauterine contraceptive devices (IUDs) when the threads are not visible at the external cervical os ('lost threads'). METHODS This was a prospective cohort study of consecutive women referred for ultrasound examination because of lost IUD threads. The procedures were performed under local anaesthesia in ...

Retrieval of a Disconnected Left Atrial Appendage Occluder with Endoscopic Grasping Forceps

Automatic Layered 3D Reconstruction of Simplified Object Models for Grasping

Most grasping systems require complete CAD models as input, but building these models automatically is not straightforward. We propose a strategy for approximating complete models of previously unknown objects from a single 3D scan of a cluttered scene. We achieve this by exploiting common symmetries in objects of daily use, and by handling overand under-segmentation issues. The idea is to use ...

Manual Removal of Primary Posterior Capsular Plaques Using Retinal End-Grasping Forceps

INTRODUCTION Primary posterior capsular plaques can be highly adherent to the posterior capsule leading to possible posterior capsular rupture during attempted removal. Here we describe a novel method for posterior capsular plaque removal using a technique inspired by the experience of retina surgeon in the peeling of membranes from the posterior pole. METHODS Retinal end-grasping forceps wer...
