Problems solved by technology
Some early tumors can be resected endoscopically to achieve a radical cure. Endoscopic submucosal high-frequency electrosurgical dissection is a commonly used surgical method; currently, high-frequency electric knife is commonly used in treatment, but the high-frequency electrosurgical knife seen in the market currently Poor controllability of the direction of the electric knife, especially in early tumor cutting and treatment will increase the difficulty, bringing many unfavorable factors to both doctors and patients
[0003] In addition, one type of traditional high-frequency electric knife can be injected, and the other is an electrode part with a ball head. If more complicated operations occur in medical diagnosis, two types of electric scalpels are needed, and operations are frequently added during use. Time affects the efficiency of surgery

The present invention relates to the technical field of medical devices, in particular to a multifunctional composite high-frequency electric knife, which includes an electrode part, a metal rod, a sleeve and an operating part, the electrode part is connected to the sleeve through a metal rod, and the operating part is connected to the sleeve , the electrode part includes a ceramic head and a cylindrical electrode, one end of the ceramic head is set on one end of the metal rod, the cylindrical electrode is set on one end of the ceramic head, the other end of the ceramic head is provided with a pointed hole, the pointed hole communicates with the metal rod, and the operation part It includes a pull ring of the main body, a liquid delivery pipe joint, a sliding part and a connector part. The liquid delivery pipe joint is externally connected with a liquid storage device through a hose, and the connector part is externally connected with a high frequency generating device. In the present invention, a pointed hole is arranged at one end of the ceramic head, and the pointed hole is connected with one end of the metal rod, and the other end of the metal rod is connected with the sleeve. The pipe joint communicates with the barrel hole, so that the ceramic head not only has the function of high-frequency cutting, but also has the function of injecting water.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a multifunctional composite high-frequency electric knife. Background technique [0002] With the development of endoscopy and people's attention to health, more and more early tumors of the digestive system are found. Some early tumors can be resected endoscopically to achieve a radical cure. Endoscopic submucosal high-frequency electrosurgical dissection is a commonly used surgical method; currently, high-frequency electric knife is commonly used in treatment, but the high-frequency electrosurgical knife seen in the market currently Poor controllability of the direction of the electrosurgical knife, especially in early tumor cutting and treatment will increase the difficulty, bringing many unfavorable factors to both doctors and patients. [0003] In addition, one type of traditional high-frequency electric knife can be injected, and the other is an electrode part with...
