[0002] The three key surgical electrode knife utilizes the heat generated when high-frequency high-voltage current contacts with tissue to realize the separation and coagulation of muscle tissue, and during the operation, the doctor can control the intensity and mode of the current by selecting different operation buttons, so as to realize the purpose of cutting and hemostasis.

[0003] The existing electrode knife head and electrode handle are fixedly connected, so that the electrode knife head and the electrode handle cannot be disassembled and replaced, but during use, the knife head is gradually worn out, which reduces the cutting efficiency, increases the maintenance cost, and different operations or use scenarios require different knife heads, so that the knife head cannot be quickly replaced, and the most suitable cutting tool cannot be flexibly selected according to the operation progress and the patient's condition, which has limitations.

[0004] The reason for this problem is that the knife head is the most easily worn part of the electrode knife. If the knife head cannot be replaced, the degree of wear of the knife head will gradually increase with the increase of the use time, which will reduce the cutting efficiency of the electrode knife and even cannot complete the expected cutting task. When the knife head is worn or damaged, the doctor needs to send the entire electrode knife back to the manufacturer for repair or replacement. This will increase the repair cost and time cost, and may also affect the smooth progress of the operation. The doctor needs to prepare multiple electrode knives, and needs to spend a lot of time to find the required electrode knife during use, which increases the operation time and complexity, and cannot guarantee that each electrode knife can be used normally, which has limitations. Therefore, we propose a three key surgical electrode handle to solve the above problems. UTILITY MODEL CONTENTS
