Background technique
Nowadays there are two types of the scalpels that doctor generally uses, and one kind is willow leaf formula scalpel, is divided into blade and knife handle, makes
Used time, a hand-held knife handle, the other hand clamp blade with needle forceps, are embedded in knife handle front end recess, then blade is clipped with needle forceps
?.Another kind is electric knife, is a kind of electrosurgical unit for replacing mechanical operation knife to carry out tissue cutting, by effective
The high-frequency high-voltage current that eletrode tip generates heats tissue when contacting with human body, realizes the separation to injected organism tissue and coagulates
Gu and then achieving the purpose that cutting and hemostasis.
Willow leaf formula scalpel: it is cut by doctor's wrist strength, cutting force degree, depth, angle and range are difficult to essence
It really holds, encounters that narrow and deep notch or notch are smaller to be, operation and its difficult.
Electric knife: electric knife have very strong heat-conduction effect, can damage adjacent tissue, especially blood vessel, nerve,
And this damage is not easy to discover during surgery, while electric knife is larger to tissue damage, and Yi Yinqi tissue necrosis leads to hand
The disunion of art notch or healing time important case field increase patient suffering and incidence of complications;The principle of electric knife
It is that cutting purpose is reached by moment high-frequency current, needs to form electric current in patient's body, when electric knife cathode and skin contact surface
Easily lead to skin scald when smaller;Since electric knife must have electric current by human body, the patient equipped with pacemaker prohibits
Avoid use;Electric knife can also generate a large amount of toxic gases in use, generate threat to medical staff's health, more
More electric knives generates spark, contains alcohol in many thimerosals, is easy to cause fire, jeopardizes doctors and patients' life.
