Problems solved by technology
The insulation function can protect the front tissue from cutting, which can greatly increase the safety of the operation. If there is a more complicated operation in medical diagnosis, when two functions need to be used at the same time, the surgical instruments are frequently replaced during use, which greatly increases the operation time. affect the efficiency of surgery

The invention discloses a novel multifunctional compound high-frequency electric knife, which comprises an electrode part, a sleeve and an operation part, wherein the electrode part is connected with the operation part through the sleeve; the electrode part comprises a ceramic head, a hollow metal rod and a triangular electrode; one end of each of the ceramic head and the triangular electrode is mounted on one end of the hollow metal rod in a sleeving manner; the other end of the ceramic head is provided with an apical hole; the apical hole is communicated with the hollow metal rod; an inner circumferential layer of the hollow metal rod is coated with an insulation material; the operation part comprises a main body pull ring, a liquid conveying pipe joint, a sliding component and a connector part; the liquid conveying pipe joint is externally connected with a liquid storage device through a hose; the connector part is externally connected with a high frequency generating device. According to the novel multifunctional compound high-frequency electric knife, one end of the ceramic head is provided with the apical hole; the apical hole is connected with one end of the hollow metal rod; the other end of the hollow metal rod is connected with the sleeve; a sleeve hole is arranged in the sleeve; the operation part is provided with the liquid conveying pipe joint; the liquid conveying pipe joint is communicated with the sleeve hole; in this way, the ceramic head also has a water injection function while having a high-frequency incision function.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel 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 digestive system are found. Some early tumors can be resected endoscopically to achieve the purpose of radical cure. [0003] The functions of the high-frequency electric knife currently seen in the market are still limited: it has the function of insulation but not the function of water injection, and the function of water injection but not the function of insulation, especially in the early tumor cutting and treatment, which will increase the difficulty, which is very difficult for doctors and patients. There are many disadvantages. [0004] In addition, one of the traditional high-frequency electric scalpels is a water-injectable non-insulated knife, and the other is an insul...
