Electrode for neurotic electrophysiological monitoring in laparoscopy

Abstract

The invention belongs to the field of medical instruments and auxiliary devices, and relates to an electrode for neurotic electrophysiological monitoring in laparoscopy. A probe electrode is composedof a head, an electrode stem, a handle and a guide line. The head is in a needle type, a round cake type or a spherical type, the head is located at the top end of the electrode stem, and the guide line penetrates through the handle and is welded to the other end of the electrode stem. According electrode for neurotic electrophysiological monitoring, the application limitation caused by body figure differences of patients does not exist; extra current does not be generated, tissue burn does not be generated, and the disturbance by bioelectricity of surrounding tissues is little; a probe is a blunt end, and vice injury is little in the operation and moving process; certain elasticity and plasticity are achieved, safe application can be achieved in a laparoscopy environment, certain degree of bending can be automatically reset, and the probe shape can be adjusted according to intra-operative demands and the monitoring effect is not affected; and recording electrode is not required to beremoved during neurotic electrophysiological monitoring, image analysis is not affected, and the operation is simple, convenient and standard.

Description

technical field [0001] The invention belongs to the field of medical equipment and auxiliary devices, and relates to an intraoperative monitoring device used in a laparoscopic environment, in particular to a neuroelectrophysiological monitoring electrode used in laparoscopy, and the monitoring electrode is suitable for pelvic cavity in a laparoscopic environment Noninvasive electrophysiological monitoring of the autonomic nervous system. Background technique [0002] The prior art discloses that in clinical surgical treatment of colorectal cancer, radical resection is the primary task of clinical treatment, but the pelvic autonomic nerve injury caused by extensive lymph node dissection and total mesorectal resection often brings voiding dysfunction to patients , sexual dysfunction (ED) and a series of problems. On the premise of meeting the requirements of R0 resection and minimally invasive tumors, the guarantee of quality of life is a new requirement for patients in the m...

AI Technical Summary

Problems solved by technology

In current clinical practice, pelvic autonomic nerve preservation relies on the operator's experience in surgery and anatomy as well as visual observation, and there is no exact technical monitoring method to improve its accuracy and reliability; it still has the following defects: The pursuit of lymph node dissection may lead to destructive damage to neurological function and affect the quality of life of patients; excessive emphasis on the preservation of neurological function may easily lead to incomplete lymph node dissection and residual tumors, leading to tumor recurrence in a short period of time and shortening the survival time of patients, etc.

[0003] At present, clinical practice urgently needs probe electrodes for laparoscopic neurophysiological monitoring that can overcome the above defects, so as to solve the inaccurate problem of neuroprotection that needs to rely on experience accumulation and visual assessment in practice.
