In general, quality assurance represents a way to avoid
mistakes in a product or service, and prevents problems. It is a part of the
quality management and its focus is on maintaining the quality and integrity of
a product or service.
When it comes to surgical tools, they represent particular
objects that have to meet some very high standards, because some people`s life
may depend on their quality and reliability. Cleaning and maintaining them
regularly is a standard practice, which ensures they are in proper working
order.
A quality test for assessing the quality and efficiency of surgical
tools may include but not be limited to:
· A drop test for needle holders, scissors, clamps and other similar instruments
The specialist holds the instrument upright and lightly, opens it and then let its upper part go free. It should not slam loosely to the closed position, but only close about two-thirds of the way.
· An approximation test for holders such as clamps or bone cutters
The device is held up to light. If light can be spotted passing through the jaws, the alignment is not god and the instrument has to be replaced with one that allows surgeons to operate safely, without wobble.
· A plastic bag test for specialized clamps
The specialist gets a plastic bag, fills it with water and
uses a clamp to grasp a corner of the bag. When the clamp is removed, the bag
must be intact, with no perforation, just with some teeth impressions.
