Abstract

The invention provides an endoscope electrode system for an electromagnetic knife surgery. The system comprises control equipment, an endoscope electrode and a corresponding cable, wherein the endoscope electrode is connected with the control equipment through the cable; the control equipment is used for controlling the output of electromagnetic signals required by the surgery; the output impedance of a built-in circuit in the control equipment is matched with the input impedance of the cable, and is smaller than the characteristic impedance of the cable; the characteristic impedance of an endoscope electrode cable is greater than the characteristic impedance of the cable; a metal electrode connected with a core wire of the cable is used as a positive electrode; and a metal conductor shielding layer connected with a shielded wire of the cable is used as a negative electrode. The endoscope electrode system for the electromagnetic knife surgery has the advantages that the energy output efficiency of the endoscope electrode system can be improved, so that the focusing performance of the output energy of the endoscope electrode is good; and the surgery safety is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscopic electrode system for electromagnetic knife surgery. Background technique [0002] When using the electromagnetic knife surgery system for intracranial surgery, a new minimally invasive surgical method is to make a small hole in the skull, insert an endoscope, and use a long and thin endoscopic electrode to enter the brain through the endoscopic channel, While observing and confirming the state of the lesion area through the camera lens, the endoscopic electrode is controlled to perform surgical operations. However, in narrow areas such as brain surgery and spinal surgery, the operating channel of the endoscope has an inner diameter of only about 2 mm, and it needs to work in effusion or perfusion fluid. The output current signal of the traditional high-frequency surgical device cannot focus the energy of the current power at one point in the conductor e...
