Self-adaptive dynamic neutral electrode contact quality detection method

Abstract

The invention discloses a self-adaptive dynamic neutral electrode contact quality detection method. The self-adaptive dynamic neutral electrode contact quality detection method comprises the following steps of: measuring an equivalent resistance value after inserting two negative plates, recording the resistance value as an initial value if the equivalent resistance value is judged to accord with a first resistance value range, monitoring a detection value of the two negative plates in real time, judging whether the detection value is greater than a threshold value when the detection value is not less than the initial value, and if the detection value is greater than the threshold value, giving an alarm; if the detection value is not greater than the threshold value, continuously monitoring; when the detection value is smaller than the initial value, updating the detection value to be the initial value, and updating the dynamic threshold value; if it is judged that the equivalent resistance value does not accord with the preset first resistance value range, carrying out alarm prompting; after the single negative plate is inserted, monitoring the detection value of the single negative plate in real time, and continuously monitoring if the detection value accords with a preset second resistance value range; and, if the detection value dose not accord with the preset second resistance value range, giving an alarm. According to the detection method, dynamic adjustment and judgment are detected in real time, so that thermal damage to a patient caused by the contact quality problem of the negative plate is avoided; and the medical safety is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an adaptive dynamic neutral electrode contact quality detection method. Background technique [0002] As an important part of the high-frequency surgical system and the patient's current loop, the neutral electrode directly provides a safe return path for the current generated by the patient's functional operations such as cutting and coagulation, and prevents the local temperature from being too high to cause burns to the patient. The function of the neutral electrode negative plate will also directly affect the safety of patients, so the negative plate is an important part that cannot be ignored in the electrosurgical high-frequency operation system. [0003] Under the pulse of a certain frequency, the single-piece neutral electrode has a good contact if the resistance value is not greater than the unipolar threshold; the two-piece neutral electrode has a good contact when the...

Problems solved by technology

[0004] The present situation that the current contact quality detection method feeds back the overall contact quality of the neutral electrode has the following disadvantages: 1) Due to the currently used method, there is a large resistance feedback error, and there is a risk of falsely triggering an early warning; 2) when the contact quality early warning or After exceeding the limit, the operation can only be suspended, and the medical staff can only apply pressure blindly to improve the contact quality, or replace a new neutral electrode; 3) The current warning value or alarm value is still a fixed value, which cannot fully meet the actual clinical use need
