Surgical Instruments for Robotic Microsurgery
• Micro-scale surgery requires a very technically advanced skill set, including high hand-eye coordination and little-tono hand tremor. • To improve microsurgical procedures, such as vein suturing, we have developed tools for the REMS, a cooperativelycontrolled surgical robot that reduces tremor when operating. • Our goal is to design effective needle holders and validate the use of the REMS by...
متن کاملQuality of surgical instruments.
INTRODUCTION Many surgeons will have encountered the scissors that would not cut, and the artery clip that comes off in a deep difficult location, but it would be reasonable to assume that new instruments should be of assured quality. This study reports the surprising findings of a local quality control exercise for new instruments supplied to a single trust. MATERIALS AND METHODS Between Jan...
متن کاملLoad sensing surgical instruments.
Force and pressure sensing technology applied to smart surgical instruments as well as implants allow to give a direct feedback of loads to the surgeon lead to better reliability and success of surgical operations. A common technology used for sensors is low-cost piezoresistive thick-film technology. However, the standard thick-film firing conditions degrade the properties of medical alloys. In...
متن کاملHand-Held Force Magnifier for Surgical Instruments
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...
متن کاملA cleaning protocol for rotary nickel-titanium endodontic instruments.
BACKGROUND The cleaning of endodontic and all dental instruments prior to sterilization is a prerequisite for their processing for re-use. This study aimed to develop a clinically practical cleaning protocol for rotary nickel-titanium (NiTi) endodontic files prior to sterilization. METHODS Cleaning experiments were conducted on six different types of files that had been used on human teeth. T...
