Pump for Arthroscopic Use

A new pump designed for use during arthroscopy, minimally invasive surgery on joints, provides consistent pressure and is easy to use.

In any arthroscopic procedure, a pump controls the flow of sterile fluid into the joint being treated. This fluid distends the joint area, creating a work space for the surgeon. The pressure within the joint must be sustained and be high enough to minimize the blood flow into the area so the surgeon will have a clear field of view. The Dyonics 25 pump provides consistent pressure and accurate measurements.

The pump has twin transducers and features a variety of snap-in tube cartridges that provide various options, depending on the facility's surgical volume. One option features a two-zone "day tubing” design, configured for centers that perform multiple procedures each day. One zone remains connected to the pump for the day, and the other is changed with each procedure, which lowers the cost per procedure. A one-way valve in the day tubing prevents fluid transfer from one patient to another.

"Having a quality pump is essential in minimally invasive surgery, but surgical pumps in the marketplace today are typically difficult to set up, to use, and to troubleshoot,” said Dr. Joseph Abate, of the University of Vermont (Burlington, USA). "By comparison, the Dyonics 25 pump is strikingly simple to use, and maintains a clear field of view for all my procedures without a lot of adjustment to the equipment.”

The Dyonics 25 is the product of Smith & Nephew Endoscopy (Andover, MA, USA), a global medical technology business, specializing in orthopedics.
