Endoscope.

A Simple Stereoscopic Endoscope

A very simple method is described for producing and viewing stereoscopic endoscopic images. The addition of two simple prisms to the end of a conventional television-monitored endoscope with a simple viewing device produces a stereoscopic endoscope which appears to be suitable for surgical use.

Endoscope-assisted myringoplasty.

INTRODUCTION To date, myringoplasty conducted under the operating microscope has been found to have its limitations. With the introduction of the endoscope into other branches of surgery, there have been attempts at its utilisation in otology. METHODS Endoscope-assisted myringoplasty was carried out in 50 patients aged 18-45 years using the temporalis fascia graft. The middle ear was examined...

Urogenital photoacoustic endoscope.

Photoacoustic (PA) endoscopy for human urogenital imaging has the potential to diagnose many important diseases, such as endometrial and prostate cancers. We have specifically developed a 12.7 mm diameter, rigid, side-scanning PA endoscopic probe for such applications. The key features of this endoscope are the streamlined structure for smooth cavity introduction and the proximal actuation mech...

Catheter-based photoacoustic endoscope.

We report a flexible shaft-based mechanical scanning photoacoustic endoscopy (PAE) system that can be potentially used for imaging the human gastrointestinal tract via the instrument channel of a clinical video endoscope. The development of such a catheter endoscope has been an important challenge to realize the technique's benefits in clinical settings. We successfully implemented a prototype ...
