A cavity electrode

Abstract

A channel electrode, comprising an upper shell and a lower shell made of an insulating material with windows, an upper electrode and a lower electrode made of a conductive material; the conductive material of the upper electrode and the lower electrode is made of a metal piece The upper shell and the lower shell are fixedly assembled into a hollow geometric structure by a positioning device; the upper electrode and the lower electrode are respectively embedded in the upper shell and the lower shell, and part of the surface penetrates the upper and lower The window of the shell is exposed; the end faces of the upper shell and the lower shell are respectively provided with through holes, and the tail end faces of the upper electrode and the lower electrode are provided with bosses; The connecting device is inserted into the through hole, passes through the positioning hole of the positioning device, and is in conflict with the boss to form an elastic deformation tight fit. The invention has greatly improved electrical conductivity, low manufacturing cost and strong working reliability.

Description

【Technical field】 [0001] The invention belongs to a medical device, in particular to a low-resistance cavity electrode capable of collecting and transmitting electrophysiological signals. 【Background technique】 [0002] The pelvic floor muscles are like a hanging net, tightly hanging the urethra, bladder, vagina, uterus, rectum and other organs, so as to maintain their normal positions so that they can perform their functions. Pelvic floor muscles are closely related to urinary control, urination, defecation, and sexual life. Dysfunction of pelvic floor muscles may lead to pelvic floor organ prolapse, urinary incontinence, fecal incontinence, constipation, pelvic floor pain, sexual dysfunction, etc. disease. The use of electrophysiological methods to screen, evaluate or treat the functional status of the pelvic floor muscles has important clinical significance. This requires the use of a cavity electrode inserted into the vagina or rectum to cooperate with the diagnosis an...

Problems solved by technology

[0004] In the prior art, the cavity electrodes drawn out by connecting wires and metal electrodes after welding conduction, although their conductivity is low, still need welding process and connecting wire parts, which can further reduce material cost, production cost and defective rate, The need to avoid environmental pollution and reduce resource consumption
