Use of the phaco tip technique for lens cleavage and removal does not require manual hydrodissection using a syringe and cannula, or cortical removal using an irrigation/aspiration tip. The phaco tip is the only surgical instrument required for this technique. Its advantages include maintaining a stable intraocular pressure during cortical cleaving hydrodissection and lens removal, which includ...

The procedures for purchasing surgical instruments and consumables are similar to those for purchasing equipment, which were addressed in our “Equipment for eye care” issue (number 73, September 2010). The major difference with consumables is that the number of items in stock (the ‘stock level’) must be monitored constantly. Consumables are generally fast moving and require frequent replacement...

laparoscopy or minimally-invasive surgery is a surgical technique in which the surgical operations are performed via a few small incisions. this kind of surgery has fewer complications over open surgery. finding methods for shortening the time of laparoscopic surgeries can improve operating room efficiency. an approach to shortening the time of laparoscopic surgeries is identifying the interrup...

The greatest burden of surgical disease exists in low- and middle-income countries, where the quality and safety of surgical treatment cause major challenges. Securing necessary and appropriate medical supplies and infrastructure remains a significant and under-recognised limitation to providing safe and high-quality surgical care in these settings. The majority of surgical instruments are sold...

BACKGROUND AND OBJECTIVES Few standardized testing procedures exist for instruments intended for Natural Orifice Translumenal Endoscopic Surgery. These testing procedures are critical for evaluating surgical skills and surgical instruments to ensure sufficient quality. This need is widely recognized by endoscopic surgeons as a major hurdle for the advancement of Natural Orifice Translumenal En...

For ease of use and to aid precision, left-handed instruments are invaluable to the left-handed surgeon. Although they exist, they are not available in many surgical centres. As a result, most operating theatre staff (including many left-handers) have little knowledge of their value or even application. With specific reference to cardiac surgery, this article addresses the ways in which they di...

The Northwest Society for Classical Studies (NWCS) was honored and privileged to have Professor Larry Bliquez speak on one of his favorite topics, the surgical instruments found in classical archeological sites and described in classical literature. Professor Bliquez is a distinguished and popular University of Washington professor, trained in classical (Latin and Greek) philology, winner of th...

In radiosurgery, a moving beam of radiation acts as an ablative surgical instrument. Conventional systems for radiosurgery use a cylindrical radiation beam of fixed cross section. The radiation source can be moved only along simple, standardized paths. A new radiosurgical system based on a six-degree-of-freedom robotic arm has been developed to overcome limitations of conventional systems. We a...

background and objectives: identification of surgical instruments in laparoscopic video images has several biomedical applications. while several methods have been proposed for accurate detection of surgical instruments, the accuracy of these methods is still challenged high complexity of the laparoscopic video images. this paper introduces a surgical instrument detection framework (sidf) for a...

The objective was to verify the association between time needed for room cleaning (TLPS) and the surgery size, and related advantages and difficulties faced by the circulator of the room asszgned to this task. A mixed method, with a transverse quantitative, retrospective approach, using a sample of 3095 surgeries performed,from January to June 2011, and a qualitative approach using a Thematic C...
