Description

TECHNICAL FIELD

[0001] The utility model relates to electric knife head technical field, especially in one off multifunctional high frequency electric knife head. BACKGROUND

[0002] In thoracic surgery, whether open surgery or endoscopic surgery, it is inevitable to encounter adhesion, which is mostly caused by inflammation, tuberculosis, trauma, tumor radiotherapy and chemotherapy, targeted therapy, immunotherapy, etc. Adhesion is divided into many types, such as membranous adhesion, cord-like adhesion, diffuse adhesion, etc. There are small blood vessels in the adhesion tissue, which is easy to bleed when cutting. The electric knife will denature protein during the adhesion process, causing the small blood vessels to close and stop bleeding, but it will also cause the formation of many carbon substances, which will stick to the electric knife blade, requiring repeated wiping to avoid affecting the operation.

[0003] The adhesion problem encountered in thoracic surgery is how to contact the adhesion and cut it off, so that the operation can be smoothly performed. However, some adhesions, such as lateral chest wall adhesion and deep chest cavity lesions, require a curved electric knife head to contact them, whether it is endoscopic surgery or small incision surgery or open surgery. Most of the electric knife heads used now are straight and cannot be bent, so they cannot solve the problem of lateral chest wall adhesion and deep dissection. Some can be bent, but the bending causes the entire electric knife head to loosen, which increases the risk of surgery when repeatedly rotating; the detachable electric knife head is also straight and cannot solve the problem of lateral lesion treatment.

[0004] Usually, the electric knife produces a large amount of smoke during cutting and coagulation, especially when dealing with severe diffuse adhesion, which is particularly serious. The amount of smoke produced is extremely large. Smoke itself is harmful to the human body, especially for patients with infectious diseases such as tuberculosis and AIDS. The smoke may contain live Mycobacterium tuberculosis and viruses, which can harm the personnel in the operating room, especially the lead surgeon, who will inhale the smoke into his lungs first. Although there is a smoke aspirator, the effect is not good. Because only the root of the smoke is sucked, too much smoke will spread into the operating room.

[0005] The electric knife head generates very high temperature during coagulation and cutting, such as temperature above 100℃ in the cutting mode. This high temperature is used for cutting tissue, and in the coagulation mode, the temperature range is 60-100℃, mainly for hemostasis and coagulation of tissue. If blood vessels or organs are accidentally damaged, it will cause heat damage. Therefore, local cooling and reducing the side effects of the electric knife are also the future development trend.
