Until quite recently, I had been in tlie habit of thinking, and indeed sometimes of teaching, that when the obstetric forceps slipped off the head during the operation of extraction, the instrument had been unskilfully applied. Within the last month I have changed my views on this point entirely. Up till October of this year I had no personal experience of the accident, but during that month I ...

Endoscopic surgery has recently been adopted in various surgical operations. Forceps stuck through trocars into the abdominal or chest cavity, dissects and grasps internal organs. Due to their xed shapes, the current forceps limit the skill of surgeons. We have worked on the development of active forceps adoping shape-memory-alloy pipes and coaxicially assembling them. In this paper, we show se...

is described a method of tying ligatures by means of artery forceps. On this one has developed a technique by which all manoeuvres of ligaturing and suturing are done by means of pressure forceps, so that one may perhaps describe it as " The Pressure Forceps Technique." One has always seen in the so-called " spoon and fork operation on bone, brain and joint an element of r^v introduced by hand ...

A handheld Smart Micromanipulation Aided Robotic-surgery Tool (SMART) micro-forceps guided by a fiber-optic common-path optical coherence tomography (CP-OCT) sensor is presented. A fiber-optic CP-OCT distance and motion sensor is integrated into the shaft of a micro-forceps. The tool tip position is manipulated longitudinally through a closed loop control using a piezoelectric motor. This novel...

During the process of human childbirth, obstetric forceps delivery is a justified alternative to Caesarean section when normal vaginal delivery proves difficult or impossible. Currently, training of forceps interventions is done directly on patients due to the lack of realistic training facilities. The research presented in this paper demonstrates a first implementation of an obstetric forceps ...

Using a Potential Field Source Surface model (PFSS), we study magnetic field overlying erupted filaments in solar active regions. The filaments studied here were reported to experience a kink instability or a torus instability. The torus instability leads to a full eruption, while the kink instability leads to a full eruption or a failed eruption. It is found that for full eruption the field de...
