Abstract

The invention relates to the technical field of medical instruments, and particularly discloses a radio-frequency suction scalpel for hepatobiliary and pancreatic surgery. The radio-frequency suctionscalpel comprises a scalpel handle, an electrode connecting base and an electrode scalpel; the electrode connecting base is positioned at the right end of the scalpel handle; the electrode scalpel iselectrically connected with the electrode connecting base; a suction pump is installed at the left end of the scalpel handle; a connecting rod is fixedly connected to the left end of the suction pump;a radio-frequency generating device is installed at the left end of the connecting rod; the radio-frequency generating device is electrically connected with the scalpel handle; and a spring cable iselectrically connected to the middle of the left end of the radio-frequency generating device. According to the invention, an arranged suction tube can be matched with an arranged aspirator; when in use, a horn cover is matched and connected; the normal use of the electrode scalpel is matched; generated smoke can be absorbed; the influence on the visual field of the normal use of the electrode scalpel is avoided; meanwhile, the electrode connecting base is matched; therefore, the electrode scalpel can be replaced according to different use conditions; and various different use requirements canbe met.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radio frequency suction scalpel for hepatobiliary and pancreatic surgery. Background technique [0002] Radio frequency scalpel is a kind of energy generated by high frequency electrical signals applied to biological tissue to cut and stop bleeding. However, the electrosurgical scalpel is widely used because of its high precision and other characteristics of radio frequency scalpel. It is used in surgical operations in various departments. With the continuous development of medicine, the complexity of surgical operations has gradually increased. At the same time, the causes and principles of various malignant diseases and the means of treatment are also gradually complicated. [0003] Existing radio frequency scalpels have been difficult to meet the requirements of use, especially when performing some hepatopancreatic and biliary surgery, when the tissue needs to be di...
