Abstract

The invention provides a variable-diameter neuroendoscopic surgery working channel. The variable-diameter neuroendoscopic surgery working channel comprises a base plate; the expansion tube is of a circumferentially-closed hollow columnar structure and comprises a first edge part and a second edge part which extend in the axial direction and can relatively move in the circumferential direction; the first edge part is connected with the substrate and keeps static relative to the substrate; the adjusting assembly is connected with the second edge part; the adjusting assembly and the base plate are selectively connected or disconnected, when the adjusting assembly and the base plate are connected, the adjusting assembly and the base plate are kept static relative to each other, the second edge part and the base plate are kept static relative to each other, and when the adjusting assembly and the base plate are disconnected, the adjusting assembly can drive the second edge part to move relative to the base plate; therefore, the inner diameter of the expansion tube is changed. The variable-diameter neuroendoscopic surgery working channel can be applied to a neuroendoscopic surgery, and the inner diameter of the expansion tube can be adjusted according to needs so as to adapt to surgery needs.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a variable diameter neuroendoscopic surgical working channel. Background technique [0002] In recent years, neuroendoscopy has developed rapidly and has been widely used in brain tumors, ventricular lesions, especially hypertensive intracerebral hemorrhage. The working channel of neuroendoscopic surgery is a device that reaches the "pathological structure" through brain tissue, and is an indispensable surgical equipment for neuroendoscopic surgery. The neuroendoscopic surgical channel is generally cylindrical, and is placed in a deep position inside the brain tissue to provide an operating space for the operation. When the working channel is first implanted, its size is required to be small to minimize the mechanical damage to the brain tissue; during the surgical operation, the inner diameter of the working channel needs to be gradually increased to facilitate neuroend...
