Problems solved by technology

[0003] When people have brain lesions, doctors need to cut the cerebral cortex for treatment, and directly reach the lesion area for surgery, but there are too many nerve tissues in the brain. The tissue often accumulates and closes, which will affect the doctor's operation. It is necessary to traction and locate the nerve tissue on both sides of the cerebral cortex channel, and at the same time, the nerve tissue cannot be lost

Abstract

The invention discloses an auxiliary device for channel expansion of neuroendoscopic surgery. The device comprises a fixing plate 1, the top of one side of the fixing plate 1 is welded with an inverted U-shaped plate, the two ends of a U-shaped groove of the U-shaped plate are respectively provided a motor 3, the output end of each motor 3 is connected with a telescopic rod 2, and each telescopicrod 2 penetrates through the U-shaped plate and is provided with a vacuum suction cup; and one end of the bottom of the fixing plate 1 is welded with a fixing plate 2, the bottom of one side of the fixing plate 2 far away from the U-shaped plate is provided with a sliding plate 1, one side of the sliding plate 1 far away from the fixing plate 1 is provided with a rack 1 which is slidingly matchedwith the sliding plate 1, the end of one side of the sliding plate 1 closed to the fixing plate 2 is provided with an L-shaped support plate, and the lower part of one side of the L-shaped support plate far away from the fixing plate 2 is provided with a gear 1 which is meshed with the rack 1. Traction and fixation of the cut cerebral cortex channel is performed by the auxiliary device, doctors are aided to performed surgery, and the auxiliary device facilitate neuroendoscopic surgery to carry out normally.

Description

technical field [0001] The invention relates to the technical field of neuroendoscopic surgery, in particular to an auxiliary device for channel expansion of neuroendoscopic surgery. Background technique [0002] Neuroendoscope is a tool for observation and operation in endoscopic neurosurgery. Clinically commonly used neuroendoscopes include rigid endoscopes and flexible endoscopes, and the development of the latter has gone through two stages: fiber optic endoscopes and electronic flexible endoscopes. Neuroendoscopic surgery has become one of the main development directions of modern minimally invasive neurosurgery. [0003] When people have brain lesions, doctors need to cut the cerebral cortex for treatment, and directly reach the lesion area for surgery, but there are too many nerve tissues in the brain. The tissue often accumulates and closes, which will affect the doctor's operation. It is necessary to traction and locate the nerve tissue on both sides of the cerebr...
