Problems solved by technology

But its disadvantage is that in the process of establishing the brain channel, because the length of the balloon is much smaller than the length of the required brain channel, the balloon needs to be expanded and advanced several times to complete the entire brain channel.
The balloon needs to be expanded and deflated every time it advances, so the balloon needs to be expanded and deflated repeatedly to make it advance gradually, making it time-consuming and laborious to complete the placement of the entire tubular brain compression plate
Moreover, this kind of movement and expansion not only tends to cause lateral stretching injury to the brain tissue, but also easily causes longitudinal stretching injury to the brain tissue, and repeated operations also increase the entire operation time, which is not conducive to the smooth operation

Abstract

The invention relates to a brain operation expander and a brain channel establishing method for brain operation under neuroendoscopy using the brain operation expander, and relates to the technical field of medical treatment. A technical scheme includes through matching length of a sacculus with length of a brain spatula, the length of the brain spatula being required length of a brain channel, the sacculus can be sent to proper depth in one time to make the sacculus expand. The length of the sacculus satisfies length requirement of the whole brain spatula, that is, establishment of the brainchannel can be completed in one time. Compared with a method in the prior art that a sacculus gradually drives the brain spatula to go forward step by step through repeated expansion and contraction,operation time is shortened, and meanwhile brain tissue protection is realized to the maximum extent, so as to provide guarantee for optimal rehabilitation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dilator for brain surgery and a brain channel establishment method using the dilator. Background technique [0002] Ventricular hemorrhage is a common acute and severe disease of the nervous system. Among them, ventricular system hemorrhage casting is a common type of ventricular hemorrhage, which is prone to lead to acute severe hydrocephalus and has a high fatality rate. Emergency hematoma evacuation and dredging of the cerebrospinal fluid circulation pathway are required. With the development of microsurgical technology, especially the emergence of neuroendoscopic technology, small channels directly entering the ventricle can realize the removal of hemorrhage in the ventricular system and relieve hydrocephalus. Therefore, developing a channel that can reach the ventricle with minimal trauma and realize continuous communication between the ventricle and the ventricle...
