Abstract

The invention belongs to the technical field of neuroendoscopy auxiliary equipment, and particularly relates to neuroendoscopy stereotactic surgery auxiliary passage equipment. The neuroendoscopy stereotactic surgery auxiliary passage equipment comprises a passage tube, a limiting plate, a partition unit and a flushing unit; the limiting plate is of an annular structure and fixedly connected to the end of the passage tube; the partition unit comprises a rotating shaft, a fixing ring, a limiting rod and partition plates; and the fixing ring is located in the middle of an inner hole of the passage tube. According to the invention, through the effect of the passage tube, a stable working passage is guaranteed to be established between the surface layer of a minimally invasive wound and a diseased part which needs to be treated in the body of a patient; and the interior of the passage tube is divided into a plurality of sub-passages which are not interfered with one another through the partition plates evenly arranged on the side wall of the rotating shaft nested in the fixing ring, so that a neuroendoscope and other surgical instruments can simultaneously extend into the passage tube along different sub-passages and treat the diseased part, and different surgical instruments acting at the same time do not interfere with each other, thereby ensuring that the treatment process is successfully carried out.

Description

technical field [0001] The invention belongs to the technical field of neuroendoscope auxiliary equipment, in particular to a neuroendoscope stereotaxic operation auxiliary channel equipment. Background technique [0002] Stereotaxic surgery is one of the important diagnosis and treatment methods of minimally invasive neurosurgery. It uses imaging positioning and orientation instrument guidance to place microscopic instruments such as microelectrodes, puncture needles, and biopsy needles into specific targets in the brain; through recording electrophysiological , Leaving tissue samples, producing damaged lesions or removing lesions, etc., to diagnose and treat various diseases of the central nervous system. In the process of stereotaxic surgery, neuroendoscopic equipment is mainly used for positioning and directional precise treatment of the diseased part of the patient. Among them, compared with conventional neurosurgery, neuroendoscopic surgery has the characteristics of ...
