A soft channel for neuroendoscopic surgery and its establishment method

Abstract

The invention discloses a soft channel for endoscopic neurosurgery. The soft channel includes an air bag and is characterized in that the air bag includes an inner wall and an outer wall; an enclosedcavity is formed between the inner wall and the outer wall and connected to a conveying assembly; the center of the air bag is provided with a cavity; a screw rod is arranged in the cavity; one end ofthe screw rod is exposed out of the air bag, and the other end of the screw rod is provided with an endoscope; the screw rod is provided with a contraction ring used for contracting the air bag; andthe end, close to the endoscope, of the air bag is provided with a transparent film. Through the air bag, the screw rod, the contraction ring, a conveying device and other structures, the channel thatcan reach ventricles with minimal trauma and can realize the continuous internal and external communication of the ventricles and the establishing method thereof can be provided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a soft channel for neuroendoscopic surgery and a method for establishing it. Background technique [0002] At present, in primary hospitals, neuroendoscopy is more and more widely used and has become an indispensable surgical tool. Ventricular hemorrhage is a common acute and severe disease of the nervous system. Among them, ventricular system hemorrhage casting is a kind of Common type, easy to cause acute severe hydrocephalus, has a high fatality rate, needs hematoma evacuation for treatment, and for this type of operation, the surgical channel is our first problem to be solved, the existing technology also provides a flexible brain expansion The flexible brain tissue retraction can be achieved by inflating the balloon, and then the tubular brain compression plate is inserted into the brain tissue following the balloon to establish a brain channel. However, in the proce...

[0002] At present, in primary hospitals, neuroendoscopy is more and more widely used and has become an indispensable surgical tool. Ventricular hemorrhage is a common acute and severe disease of the nervous system. Among them, ventricular system hemorrhage casting is a kind of Common type, easy to cause acute severe hydrocephalus, has a high fatality rate, needs hematoma evacuation for treatment, and for this type of operation, the surgical channel is our first problem to be solved, the existing technology also provides a flexible brain expansion The flexible brain tissue retraction can be achieved by inflating the balloon, and then the tubular brain compression plate is inserted into the brain tissue following the balloon to establish a brain channel. However, in the process of establishing the brain channel, due to the The length is far smaller than the length of the required brain channel, and the balloon needs to be expanded and advanced many times to complete the entire brain channel. Repeated expansion and contraction of the balloon makes it gradually advance, making it time-consuming and laborious to complete the placement of the entire tubular brain compression plate

Moreover, moving and expanding in this way not only tends to cause lateral stretching injury to the brain tissue, but also easily causes longitudinal stretching injury to the brain tissue. Repeated operations also increase the entire operation time, which is not conducive to the smooth progress of the operation.
