Description

TECHNICAL FIELD

[0001] The present application relates to a medical instrument, in particular to a multifunctional surgical dissector. BACKGROUND

[0002] In the medical field, the high-frequency electrotome is a common surgical instrument for surgical operation, which simplifies the operation process of the doctor and improves the safety of the operation due to its own safety and reliability. The working principle is to gather high-frequency current with high current density to directly destroy the tissue at the point in contact with the effective electrode tip. This high-frequency electrotome has high cutting efficiency, but during use, the smoke generated by the electrically burned tissue hinders the doctor's field of vision and the excessive inhalation of the operating surgeon will harm the human body. At the same time, due to the high temperature of the electrically burned tissue, the high-frequency electrotome head is easy to make the burned and charred tissue adhere to the head, affecting the use of the electrotome. Often after a while, the burned tissue is scraped off from the electrotome to continue using, which is very unfavorable for the operation. Now there is an ultrasonic surgical knife. The main mechanism of the ultrasonic surgical knife is that the main machine outputs an electric signal, which is converted into mechanical energy to produce high-frequency vibration through the transducer using the electrostrictive effect or magnetostrictive effect. Through the amplification and coupling of the amplitude rod, the knife head works and transmits energy to the local tissue of the human body, so as to achieve the purpose of surgical treatment. Due to the generation of high-frequency vibration, the knife head has a self-cleaning effect, which can solve the adhesion of tissue on the surface of the electrotome head. However, the ultrasonic cutting hemostatic knife has low cutting efficiency and cannot replace the high-frequency electrotome for use. Therefore, a multifunctional surgical dissector is needed, which can have the cutting efficiency of the high-frequency electrotome and the self-cleaning effect of the ultrasonic surgical knife, and can also be used alone as a high-frequency electrotome or an ultrasonic surgical knife.
