ophthalmic equipment, including surgical instruments and diagnostic devices, can be compared to the maintenance of a motor vehicle, something many of us understand well. If you had a car, would you drive it until the fuel runs out or until a tyre punctures, and then abandon it to buy a new car? Of course not. However, many eye care units purchase (or receive as a donation) expensive and delicat...

Robotic surgery is an exciting technology that allows the surgeon to sit at a computer console near the operating table, using mechanical arms with surgical instruments attached to them. This type of surgery is minimally invasive, and the procedure is performed through tiny incisions. This technology is widely used in the United States and is expected to evolve over time with an increase in the...

We present a novel and relatively simple method for magnifying forces perceived by an operator using a tool. A sensor measures the force between the tip of a tool and its handle held by the operator’s fingers. These measurements are used to create a proportionally greater force between the handle and a brace attached to the operator’s hand, providing an enhanced perception of forces between the...

HYPOTHESIS Exposure to certain new surgical instruments and operating room devices during procedures could cause hearing damage to patients and personnel. BACKGROUND Surgical instruments and related equipment generate significant sound levels during routine usage. Both patients and physicians are exposed to these levels during the operative cases, many of which can last for hours. The noise l...

BACKGROUND Recently, several transoral approaches for minimally invasive surgery have been developed for oropharyngeal cancer. However, all approaches have certain disadvantages. Therefore, we built and examined new surgical environments for improving the situation. METHODS Endoscopic transoral resection using a pharyngeal retractor or distending laryngoscope, rigid videoendoscope, and laparo...

There is substantial historical evidence to support the prevalence of surgical practice during ancient times in the subcontinent of India. However, in contrast to the contemporaneous Greek and Roman periods, there is a notable absence of any archaeological finds in the form of surgical instruments. Inquiries to major museums and personal contacts have not been fruitful. This lack of relevant ar...
