Product Information

Il nuovo sistema Versajet: Clicca qui per saperne di più


The innovative Versajet* Hydrosurgery system is a specialised powered surgical instrument designed to improve care for patients undergoing wound debridement in the Operating Room

Why use the Versajet Hydrosurgery System?

The Versajet Hydrosurgery System utilises a high-pressure jet of sterile saline that travels parallel to the wound surface. This high-speed jet creates a Venturi effect that enables the surgeon to simultaneously hold, cut and remove tissue, while irrigating and aspirating the wound, with a single instrument. This new technology allows the surgeon to differentiate between tissue types through technique as well as by varying power settings, therefore sparing viable tissue while precisely targeting and removing debris and damaged tissue. Rapid and effective hydrosurgical debridement using the Versajet Hydrosurgery System can help to reduce procedure times as well as potentially reducing the number of debridements each wound requires compared to traditional modalities e.g. the use of scalpel and pulsed lavage. This modality is suitable for surgical debridement of chronic and acute wounds in the Operating Room with the patient undergoing general anesthesia.

Science

Venturi effect

A high velocity stream of sterile saline jets across the operating window and into an evacuation collector, creating a localised vacuum to hold and cut targeted tissue while aspirating debris from the site

 

Tissue excision

When the operating window is orientated parallel to the tissue, excision and aspiration are performed. At higher power levels, harder or tougher tissue can be excised. The surgeon can control the cutting and aspiration effects by adjusting console power settings, hand piece orientation and hand piece pressure.

Contaminant removal

When the operating window is orientated obliquely to the tissue, the primary action becomes vacuuming and irrigation of the contaminated tissue. The closer the operating window is to parallel, the more aggressive the tissue excision - whereas the more oblique, the more gentle contaminant vacuuming. 

Applications

Versajet's unique properties enable clinicians to debride traumatic wounds, chronic wounds, or other soft tissue lesions or remove contaminants from a wound quickly and efficiently. The system is highly controllable:

  • At the lowest power levels, Versajet will function mainly as a vacuum and remove little tissue with each pass.
  • As the power is increased, tissue ablation increases, as does the ability to remove harder, tougher tissue types.
  • At the highest power levels, the Versajet system will remove non-viable tissue very rapidly and cut all but the hardest tissues.

FAQ's

Clinical and General FAQs

Q: What do the warning lights mean?

A: There are three indicator lights located to the left of the digital display

  • Door: when illuminated, an amber Door light indicates that the console door is not completely closed.
  • Pedal: when illuminated, an amber Pedal light indicates that the foot pedal is not properly connected.
  • Error: when illuminated, an Error light indicates a system error. This may be cleared by toggling the power switch off and on.

 

Q: What happens if the saline bag empties?

A: Once the system has been primed with saline, do not allow the saline bag to empty; an empty bag will allow air into the system and reduce the system's efficiency. Therefore, always change to a new saline bag before the bag in use empties. If air does enter the system, pump fluid on high setting until the system is purged of all air.

 

Q: What happens if the device tip becomes blocked with foreign matter?

A: Remove the hand piece from the wound site. Stop the jet flow by releasing the foot pedal. Remove the obstruction with forceps taking care not to touch the opening in the high-pressure jet. Once removed, depress the foot pedal and check that there is a single coherent jet flow. If the obstruction is not completely removed, repeat procedure.

 

Q: Can Versajet be used for minimally invasive surgery?

A: Versajet is intended to debride wounds of damaged, diseased or necrotic soft tissue. In addition it will remove contaminants and debris. Versajet creates a localised vacuum to hold cut and remove tissue and aspirate wounds. Versajet can be used in difficult to reach areas with limited access. Versajet is not suitable for use in areas that are required to be filled with fluid or gas for visualisation purposes as Versajet will evacuate these as it debrides.

 

Q: Is Versajet the same as pulsed lavage?

A: Versajet is not the same as pulsed lavage. Versajet is intended to debride wounds of damaged, diseased or necrotic soft tissue. In addition it will remove contaminants and debris. Versajet works in a completely different way to pulsed lavage. With Versajet a controlled tight beam of sterile saline travels parallel to the wound creating a localised vacuum that enables the surgeon to hold cut and remove tissue and debris and at the same time irrigate and aspirate the area covered. Versajet does not spray saline directly into the wound. Pulsed lavage sprays saline directly into the wound and onto debris.

 

Q: Will Versajet cut Arteries and Nerves?

A: Versajet is intended to debride wounds of damaged, diseased or necrotic soft tissue. In addition it will remove contaminants and debris. Versajet is a debridement device and at higher power settings will cut soft tissues. Versajet should be used with caution around delicate structures and should be used at low settings to begin with.

 

Q: Will Versajet cut bone?

A: Versajet is intended to debride wounds of damaged, diseased or necrotic soft tissue. In addition it will remove contaminants and debris. Versajet is not intended to cut bone, however in higher power settings it can debride wounds of small bone fragments and may remove very soft diseased bone

 

Q: Will Versajet remove bone cement?

A: Versajet is intended to debride wounds of damaged, diseased or necrotic soft tissue. In addition it will remove contaminants and debris. Versajet is not intended as a cement removal tool and is not designed to cut up or remove cement mantles or large pieces of cement mantle. However Versajet will remove smaller particles of cement from the soft tissues and joint spaces.

 

Q: Does Versajet have a cautery action?

A: Versajet is intended to debride wounds of damaged, diseased or necrotic soft tissue. In addition it will remove contaminants and debris. Accurate debridement of the soft tissue can been seen to reduce bleeding due to the ability to debride down to punctuate bleeding tissue rather than taking more tissue than desired and encouraging copious bleeding. Versajet facilitates accurate debridement of wounds by allowing the surgeon to plane down through the tissues and get very good visibility of the operative sight. Versajet does not have a cautery action.

Precautions >

 

Power Console

Front Panel

  • The Power Switch is on the lower left corner of the front panel. When the system is not in use, this switch should be in the off (O) position.
  • The Foot Switch Receptacle receives the cable connector from the external Foot Switch to allow remote operation of the system.

 

  • The Foot Switch is the only means of activating the device. It allows for direct surgeon control over console activation.
  • The digital display, located to the left of the up and down-speed control arrows on the centre of the panel, defaults to speed level 1, the lowest pressure level for the system. The up and down arrows that are immediately adjacent to the digital display can be used to increase or decrease the speed respectively.
  • Three indicator lights are located to the left of the digital display.

Rear Panel

"Door"

When illuminated, an amber Door light indicates that the console knob is not completely closed.

"Pedal"

When illuminated, an amber Pedal light indicates that the foot switch is not properly connected.

"Error"

When illuminated, a red Error light indicates that an over-pressure condition has occurred that can only be cleared by toggling the power switch off and on. If this does not resolve the issue please contact your local Smith & Nephew representative.

Disposable Handpiece Assembly with Pump Cartridge  

The Disposable Hand piece Assembly consists of two main components: the hand piece itself and a pump cartridge to pressurise the fluid. In addition to these main components, there are three hoses pre-assembled and included in the system. A bag spike hose allows the fluid from a sterile saline bag to enter the pump cartridge. A high-pressure hose then carries the pressurised fluid from the cartridge to the hand piece. Finally, the waste hose carries the saline solution and any material collected at the instrument tip from the hand piece to an appropriate waste container.

The hand piece consists of an ergonomic handle, a small diameter high-pressure tube, and a larger evacuation tube. Near the end of the high-pressure tube is a small, precise opening which regulates the size and flow of the fluid jet. The end of the evacuation tube is specifically designed to generate an appropriate vacuum for removal of material while still allowing the surgeon to visualise the wound being debrided. It also allows the fluid jet to contact tissues and material that should be cut or ablated. No external vacuum source is required.

In summary, the Disposable Hand piece Assembly controls the flow of sterile saline from the fluid supply bag through the pump cartridge, where it is pressurised, and then to the hand piece for use at the surgical site. It also ensures removal of tissue debris from the instrument tip into an appropriate waste container.

Foot Switch with Connector

The Foot Switch is connected to the Power Console through the receptacle on the front panel. It allows the surgeon to activate the instrument while working in the sterile surgical field. A missing or poorly connected Foot Switch is indicated when the "pedal" light is illuminated.

Power Cord

The Power Cord provides electrical power to the console from a wall socket.
