Electrode for prostate gasification surgery

Abstract

The invention discloses an electrode for a prostate gasification surgery, which comprises a casing. An electrode tool bit is arranged on the top of the casing, and a pair of electrode pieces is separately arranged on the electrode tool bit; a group of connecting pole pieces to be connected with a high-frequency surgical instrument are arranged on the bottom end of the casing, and the electrode pieces are respectively connected with the pole pieces through circuits; the electrode tool bit is arranged on the top of the casing, the electrode pieces are arranged on the electrode tool bit, and the electrode acts on a pathological part after the electrode is connected with the high-frequency surgical instrument through the connecting pole pieces on the bottom end of the casing; the electrode pieces are directly connected into a circuit through the pathological part without adhering a pole plate. Therefore, the aim of the electrode for the prostate gasification surgery is realized.

Description

technical field [0001] The invention relates to an electrode for surgery, in particular to an electrode for prostate gasification surgery for high-frequency surgical instruments. Background technique [0002] With the continuous development of electrosurgical techniques, vaporization of the prostate is receiving increasing attention and has gradually become a safer and more effective method for the treatment of benign prostatic hyperplasia. The principle of prostate gasification is that due to the different water content of human tissue, the electrical conductivity is different. It can be regarded as a resistor. When different currents pass through these resistors, different thermal effects will be produced. [0003] Generally, electrosurgery often uses two waveforms of current, that is, intermittent bursts of coagulation current with low energy and continuous and high-energy electric cutting current. When the electric coagulation current and electric cutting current act on ...

AI Technical Summary

Problems solved by technology

[0004] At present, the prostate gasification surgery generally adopts the unipolar cutting mode. The prostate-specific electrode connection is inserted into the foot-controlled knife socket of the high-frequency surgical instrument. The diseased part and the plate form a conduction loop. The disadvantage of this mode is that the distance between the plate and the dedicated electrode for the prostate is relatively large, and the area where the current flows through the patient is large, and the part where the plate is attached is likely to cause burns, resulting in non-patient Part damage
