PSU-400 Electrosurgical Unit

The PSU-400 Electrosurgical Unit is an advanced surgical generator designed to cut, coagulate, and blend tissues using high-frequency currents. It offers multiple modes—pure cut, blend 1/2, standard coagulation, spray coagulation, bipolar cut/coag—allowing surgeons to tailor energy delivery to specific procedures. With features like 5 W incremental control, minimal tissue sticking, auto shutdown in 5 seconds to prevent misoperation, and compatibility with endoscopic and underwater cutting (e.g., TURP), it provides versatility, safety, and precision across surgical specialties.

Features

Technical Parameters

• NEW: double-sided, dual diaphragm chestpiece for both adult and paediatric assessment.
• NEW: The paediatric side is also easily transformed into a traditional open bell by replacing the single-piece diaphragm with the supplied non-chill rim.
• NEW: chestpiece is precision-machined into an aesthetically pleasing, less angular shape.
• NEW: single-piece diaphragm instead of separate diaphragm/rim making it easier to attach and easier to clean due to the smooth unbroken surface.
• NEW: The stem features an open side indicator to easily identify which diaphragm is in operation.
• NEW: next-generation tubing gives even longer tube life with improved resistance to skin oils, alcohol and staining.
• 3M’s ‘Tunable Technology’ lets you easily switch from low to high frequency sounds by switching from light to firm pressure on both the adult and paediatric sides of the chestpiece.
• High acoustic sensitivity when performing general physical assessment.
• Laser engraving of text and symbols to personalise your scope and avoid theft/loss
• Larger ear tubes on the anatomically designed headset comfortably positioned for better sound transfer. Easy adjustment by simply squeezing or pulling apart the eartubes.
• Comfortable Snap-Tight soft seal eartips create an excellent acoustic seal to reduce ambient noise.
• No natural rubber latex or phthalate plasticisers are used in the tubing or any other component—to help protect health and the environment.
• Complement your personal style with Littmann’s large range of chestpiece finishes and tubing colours.
• Used as a diagnostic aid as part of the physical assessment of a patient.

• Can be set as required sterilization temperature, working tem. range:room tem.:+5~126 Degree.
• Can ge set as required sterilization time of heat preservation, setting range:1~99min.
• Having a low water to stop heating function.
• This product uses the high quality stainless steel SUS304. Having to work under normal conditions adequate safety strength.

• The Ambu Oval Silicone resuscitator has a special textured surface combined with the unique support strap to ensures that a comfortable and firm grip is guaranteed, allowing for effective ventilation over extended periods, without the problem of hand fatigue.
• The Ambu Oval Silicone Resuscitators is made out of a view parts that can be disassembled easily. The Ambu Oval Silicone Resuscitator can easy be cleaned and autoclaved (except the oxygen reservoir) at a temperature of 134° Celsius.
• The unique shape is small and easy to hold. The ergonomic, lightweight design of Ambu Oval Silicone Resuscitator is made for optimal user handling and support even during extended ventilations.
• The resuscitators are semi-transparent allowing for a visual check of the patient’s condition. A pressure limitation valve is optional for the adult version and has been included into the design of the pediatric versions to ensure the safety of the patient*.

* International guidelines recommend that all manual resuscitators for infant and pediatric patients should be equipped with a pressure limitation mechanism so the airway pressure does not exceed 45 cm H2O.
