The CHW-E17I High Frequency Bipolar Electrosurgical Electrical Cautery Knife uses the new high-tech product appraised by state pharmaceutical Inspection Administration.

Characteristics
I.Constant Output Power:
CHW-E17I  is similar to VALLEYLAB FORCE-2/BIRTCHER4400, having Electrocision、Blend1、Blend2、Blend3、Bipolar、Coagulation,and may move thin with the digital demonstration. Especially the electricity congeals and opens a way nearly 10,000 volts of voltage very much only, cooperating with argon car can become argon car can become argon high-frequency electric knife, The coagulation is extremely good, Has selected the biplanes negative plate, may examine the resistance function which and the human body contacts. Each kind of acousto-optic demonstration function is complete.

II.Excellent Safety:
Because this Generator adopts the full-bridge non-industrial frequency transformer high frequency switch power supply as the power source for high frequency power amplifier, the application portion of the Generator has dual insulation from the power supply of the power network, which promotes the safety guarantee for the users and the patients.

III. High Reliability:
CHW-E17I is made by advanced circuit design, which has corresponding actuations for circuit protection against various load variations in order to guarantee the normal functioning of active transistor. The comprehensively designed control circuit has strong capability against common fault operations. Besides that the critical portions adopt the imported units, the strict filtering realizes the more superior quality level of the entire Generator.

IV.The performance-to-price ratio is high:
The electricity knife present price only is approximately 1/4 of the import similar product.
