A kind of electromyography detection device combined with laparoscope and operation method thereof

Abstract

The invention discloses a myoelectric detection device combined with a laparoscope and an operation method thereof, comprising a working mirror tube, a laparoscope and a myoelectric detection electrode, wherein the inside of the working mirror tube is provided with an imaging channel and an electrode channel parallel to each other. The mirror is set in the imaging channel, and the myoelectric detection electrode is set in the electrode channel. The myoelectric detection electrode includes a medical trocar needle, an electrode, two inner sleeves and an outer sleeve with different inner diameters and nested in each other, and the medical trocar needle. It is fixed on one end of the outer cannula, and the electrode is fixed on the inner cannula. The electrode on one side of the inner cannula is introduced into the medical cannula needle and the front end of the electrode is flush with the needle tip of the medical cannula needle. The other end of the inner cannula The electrode tail on the side is connected with the biological signal acquisition system through a wire. The operation trauma of the present invention is small, can effectively alleviate the pain of the patient, recover quickly after the operation, reduce the interference factors caused by the operation, and make the experimental results more convincing.

Description

technical field [0001] The invention belongs to the technical field of medical supplies for digestive tract detection, and in particular relates to a myoelectric detection device combined with a laparoscope and an operation method thereof. Background technique [0002] The myoelectric action potential of the colon is generated on the slow wave, which is consistent with the contraction of smooth muscle and is the main driving force of propulsive movement. Therefore, as an objective electrophysiological index, the colonic myoelectric activity can indirectly reflect the dynamic state of the colon. Slow wave is a relatively regular periodic electrical activity that controls the contraction rhythm of the intestinal tract, whether it is contracted or not. At present, the recording of EMG activity is one of the important methods in the study of colon motility. In some experiments, because there are many blood vessels in the normal intestinal mucosa, it is red under the microscope,...

AI Technical Summary

Problems solved by technology

[0003] Common electrodes for gastrointestinal myoelectricity mostly use tin electrodes. The material of tin electrodes is soft, not hard enough, and has a low melting point. It is difficult to weld after disconnection.

In addition, the electrodes are usually covered with insulating tubes such as polyvinyl chloride or connected with auxiliary tools such as medical suture needles for guidance. The insulating tubes and medical suture needles will have a destructive and irreversible impact on the intestinal wall, resulting in abnormalities on the EMG. Larger interference waves appear, so ideal experimental results cannot be obtained
