High-frequency electrotome convenient to use

Abstract

The present invention provides a high-frequency electrotome convenient to use which comprises a main machine, a knife handle and a knife head, a high-frequency circuit system controlled through a controller is arranged in the main machine, a knife groove is formed in the end of the knife handle, a positive electrode cable of the high-frequency circuit system penetrates through the knife handle and then is connected with the knife groove, and the knife groove is used for installing the knife head and recognizing the type of the knife head. The controller is connected with the cutter groove so as to control the high-frequency circuit to output adaptive high-frequency electric waves to the cutter head in the cutter groove after receiving the type of the cutter head. When the tool bit is replaced, the tool groove recognizes the model of the tool bit and feeds back the model to the controller, the controller controls the high-frequency circuit system to output high-frequency electric waves with adaptive power to the tool bit, the operation that the output frequency is adjusted on the main machine first during tool replacement is reduced, and the controller further controls the high-frequency circuit system to output the maximum power to the tool bit. The tool bit is prevented from being damaged by power overload or a patient on an operating bed or an operating chair is prevented from being accidentally injured.

Description

technical field [0001] The invention belongs to the technical field of high-frequency electric knife, and in particular relates to an easy-to-use high-frequency electric knife, which is suitable for excision of uvula, soft palate and other tissues in the human body, especially in narrow openings in ENT surgery. tissue resection. Background technique [0002] High-frequency electric knife is usually used in the tissue resection of ENT. There are many kinds of high-frequency electric knife heads, such as the cutting head for main cutting, the mixed cutting head for main cutting, and the hemostatic knife for hemostasis. Head, main electrocautery, and ablation head, among them, the output power of the cutting head is as high as 120W, and the output power of the ablation head is as low as 40W, and the same host is used for all kinds of cutter heads, and the host controls the high-frequency The circuit system outputs high-frequency radio waves to the cutter head. During the opera...

[0002] High-frequency electric knife is usually used in the tissue resection of ENT. There are many kinds of high-frequency electric knife heads, such as the cutting head for main cutting, the mixed cutting head for main cutting, and the hemostatic knife for hemostasis. Head, main electrocautery, and ablation head, among them, the output power of the cutting head is as high as 120W, and the output power of the ablation head is as low as 40W, and the same host is used for all kinds of cutter heads, and the host controls the high-frequency The circuit system outputs high-frequency radio waves to the cutter head. During the operation, the doctor needs to replace the cutter head with different functions to achieve different operations. Before replacing the cutter head, the output frequency on the host needs to be adjusted to avoid outputting to the cutter head beyond its functional range. The electric wave caused damage to the cutter head, and in severe cases, it also damaged the patient's body. Especially the adjustment process of the existing high-frequency electric knife is complicated. For medical staff who are not skilled in operation or have poor psychological quality, it is very easy to Wrongly adjust the output power on the host, which makes the operation inefficient and easily causes medical accidents

[0003] In addition, there are two types of switch buttons for the existing high-frequency electric knife, one is the pedal type installed on the host, and the other is the finger-press type installed on the knife handle. The generation of high-frequency electric waves will cause harm to the human body accidentally touched. Therefore, the switch on the high-frequency electric knife is usually set to conduct the circuit after pressing the switch, and disconnect the circuit after releasing it. During the operation, someone needs to continue to step on the foot The pedal switch or the medical staff press the finger switch continuously to make the knife head and the high-frequency circuit conduct. The efficiency is reduced, and it is also not conducive to the health of medical staff; in addition, when performing uvula cutting surgery in the larynx, there is no special tool in the prior art, and there will always be problems in the cutting process of medical staff using existing tools.
