TNMI Insightra - SmartVision Arthroscopy Pump for Surgical Procedures

SHARE

The SmartVision Arthroscopy Pump, developed by Insightra, is an advanced technology designed to enhance surgical procedures through efficient fluid management. The pump features a patented technology that automatically adjusts fluid pressure and flow rates, improving the precision and effectiveness of arthroscopic surgeries. It integrates an optical detector located behind the Patient Cassette, which uses LED light deviation to distinguish between blood and debris. This allows the pump to increase fluid inflow to control bleeding or enhance fluid flow to clear debris as needed. The Double Pump RF model also connects with an RF generator, ensuring optimum settings during joint ablation. Operation relies on disposable slide-in tubing cassettes for in-flow and out-flow, maximizing sterility and efficiency. Key technical specifications include input voltage, frequency, power consumption, fuse rating, pressure range, and flow range. These features position the SmartVision pump as a vital tool for medical professionals aiming for precision and control in surgical environments.

The Double Pump RF is one of the most advanced and high-tech
arthroscopy pumps on the market. The reason for using a pump in an arthroscopic procedure is to:
  • Keep the joint distended through pressurization and expansion of the operating field
  • Compress damaged blood vessels to maintain hemostasis through increased pressure
  • Maintain visibility by flushing the operating field in a controlled way

SmartVision is a patented technology owned by Insightra, which automatically adjusts the pressure and flow when blood or debris is detected. The SmartVision function consists of an optical detector located behind the Patient Cassette. Through deviation of LED light the detector can differentiate between blood and debris and adjust fluid pressure and flow rate accordingly. When the sensor detects blood, fluid inflow is increased in steps which increase pressure, blocking off the blood vessels to stop the bleeding. When the bleeding stops, the pressure gradually decreases to its original setting. If the sensor detects debris, inflow and outflow are increased, leading to an increase in flow rate. When the debris is flushed out the pump returns again to its original settings.

The Double Pump RF has the ability to communicate with a RF generator, allowing optimal pressure and flow settings during ablation in the joint. ​The Double Pump RF controls both the in- and out-flow and consequently both pressure and flow. The pump operates through usage of disposable slide-in tubing cassettes, one cassette which controls the in-flow (Day Cassette, used for one surgical day) and one that controls the out-flow (Patient Cassette, new for every patient). The key advantages of using the Double Pump are:

  • The patented SmartVision® function
  • Compatibility with RF systems
  • Compatibility with most shaver systems on the market
  • Calculation of the true pressure in the joint (true IAP)
  • The easy-to-use Cassette technique
  • The Outflow Tracking function 
The fluid used is saline which is administrated through two types of cassettes, a “Patient” and a “Day” cassette. The Day cassette is used for one surgical day and transports the fluid from the sterile saline bag via the pump to the joint, where it connects to the arthroscope sheath.
 
The Patient cassette then transports the contaminated fluids from the joint, through an outflow cannula, via the pump and into a waste dispenser. However, today some surgeons exclude the usage of separate outflow channel (via the disposable cannula). Instead evacuation of irrigated fluids is made through the working port or through the Shaver (if the function “Shaver suction” is available on the pump).
 
Neither of these alternatives to the disposable outflow cannula is efficient when it comes to visibility, which is most often compromised due to bad fluid management performance when a proper evacuation port is excluded. The evacuation issue is one of most important areas of improvement to reach a problematic-free arthroscopic procedure with maximum visibility.
