Surgical Stop Bleeding Harmosonic Scalpel

System Description

The UHS14 System utilizes ultrasonic energy to enable haemostatic cutting and/or coagulation of soft tissue. The system consists of an ultrasonic generator, a foot switch, an optional hand switching adaptor, a hand piece, and a variety of open and minimally invasive instruments.

Ultrasonic Scalpel System UHE14

The instruments vibrate longitudinally at 55.5 kilohertz. This ultrasonic vibration at the blade enhances its cutting ability. The same vibration seals small vessels with coagulated blood and tissue proteins. Haemostasis occurs when tissue couples with the instrument. This coupling causes collagen molecules within the tissue to vibrate and become denatured, forming a coagulum.

Indications

The UHS14 System is indicated for soft tissue incisions when bleeding control and minimal thermal injury are desired. The System instruments can be used as an adjunct to or substitute for electro surgery, lasers, and steel scalpels.

Contraindications

        The instruments are not indicated for incising bone.
 
        The instruments are not intended for contraceptive tubal occlusion.

System Components

Generator 
The generator supplies the hand piece with electrical energy and facilitates selection of power levels, system monitoring, and system diagnostics.
 
Power is delivered by activating the foot switch or hand switching adaptor.
 

Hand Piece
The hand piece contains an acoustic transducer that converts the electrical energy supplied by the generator to mechanical motion. The transducer is connected to an ultrasonic wave guide/amplifier which amplifies the motion produced by the transducer and relays it to the instrument.
 
 
Instrument
The mechanical motion from the hand piece advances to the instrument, transmitting ultrasonic energy which enables
haemostatic cutting and/or coagulation of tissue.

Power Levels

The generator delivers two power levels: minimum (MIN) and maximum (MAX). The minimum power level may be adjusted by the user from Level 1 to 5. The maximum power level is always Level 5. With all instruments except the ball coagulator, use a higher generator power level for greater tissue cutting speed and a lower generator power level for greater coagulation. For the ball coagulator, higher generator power levels will provide greater coagulation. The amount of energy delivered to the tissue and resultant tissue effects are a function of many factors including the power level selected, instrument characteristics, grip force (when applicable), tissue tension, tissue type, pathology, and surgical technique.
