The novel open surgery mixed type cutter head single-pole ablation electrode with deep lighting, smoke suction and measuring functions comprises a handle assembly, a mixed type cutter head assembly, a transmission assembly, a lamplight illumination assembly, an electrode system, a light source system and a smoke suction system; a mixed type cutter head of the novel open surgery mixed type cutter head single-pole ablation electrode with deep lighting, smoke suction and measuring functions comprises a T-shaped single-pole ablation electrode and mechanical scissors, so that target tissues can be efficiently and finely cut and separated,tissues except the target tissues can be effectively protected, the mechanical scissors assembly can be further used for shearing eschar tissues, thread ends and the like, the time for replacing surgical instruments can be saved, and the surgical efficiency can be greatly improved; in addition, all keys are designed on the handle, so that the operation usability can be greatly improved, and the operation time is obviously saved; the smoke suction assembly can quickly and efficiently suck smoke generated in the surgical operation, so that the harm of the surgical smoke to doctors and nurses isgreatly reduced; the lamplight illumination assembly can efficiently and accurately illuminate a surgery operation area, the shadowless lamp adjusting operation of doctors and nurses is reduced, and the surgery safety is obviously improved while the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electrosurgical instruments, and more specifically, relates to a novel open surgery with deep lighting and smoking measurement function hybrid cutter head unipolar ablation electrode. Background technique [0002] As a basic surgical energy instrument, high-frequency electrosurgical instruments are widely used in various clinical surgical procedures, especially in open surgery. However, the unipolar high-frequency electrosurgical instruments currently used in open surgery are mainly unipolar electrosurgical pens (including tungsten needle knives often used in fine operations such as thyroid surgery, plastic surgery, and breast surgery), and most of the existing monopolar electrosurgical instruments When performing deep surgical operations (such as axillary, thoracic, abdominal and pelvic lymph node dissection), the stability of the electrosurgical pen tip in the extended state of the knife rod is poor, an...

However, the unipolar high-frequency electrosurgical instruments currently used in open surgery are mainly unipolar electrosurgical pens (including tungsten needle knives often used in fine operations such as thyroid surgery, plastic surgery, and breast surgery), and most of the existing monopolar electrosurgical instruments When performing deep surgical operations (such as axillary, thoracic, abdominal and pelvic lymph node dissection), the stability of the electrosurgical pen tip in the extended state of the knife rod is poor, and the exposed electrosurgical pen tip is easy to accidentally damage other than the target tissue At this time, surgeons often need to use surgical instruments such as ultrasonic scalpels. However, the efficiency of ultrasonic scalpels for cutting and separating tissues is low; in addition, the current electrosurgical pens or ultrasonic scalpels lack or cannot have smoking lighting, etc. at the same time. Function, there are still many deficiencies that need to be further improved. The specific deficiencies are as follows: 1. In open surgery, the cutter head of most monopolar high-frequency electrosurgical instruments has no protective layer, and the entire metal part is exposed beside the surgical target area. When performing delicate operations such as paravascular lymph node dissection, the over-exposed cutter head is likely to accidentally injure surrounding tissues; when performing deep surgery, the operating space is often significantly limited, and the length of the cutter bar needs to be further extended to complete complex and delicate operations , which greatly reduces the stability of the surgical operation, and it is easier to damage the surrounding tissues and organs. Sometimes it is even necessary to replace the surgical equipment such as the ultrasonic knife; Cutting with scissors; 3. Most of the unipolar ablation electrodes have sharp-edged electrosurgical pen blades, some of which have edges and corners on the surface. When performing blunt dissection, it may damage the surrounding tissue plane and cause bleeding; 4. High-frequency electrosurgical instruments use electric energy to cauterize and stop bleeding and cut tissue to vaporize tissue liquid. The vaporized tissue produces relatively large smoke, and the smoke contains a large amount of toxic gas. During open surgery, doctors and nurses on the operating table At the same time, the smoke will hinder the surgical field of view, which is not conducive to improving the safety and efficiency of the operation, and seriously affects the progress of the operation; 5. In open operations such as the deep mediastinum, retroperitoneal organs, and pelvic cavity (retroperitoneal tumors) , pelvic median resection, etc.), the visual field and operating space are often very limited, and the surgical lighting source cannot accurately illuminate the surgical target area, which seriously affects the surgical process and quality, and the risk of accidentally injuring peripheral organs and blood vessels increases significantly
