Multidirectional adjustable hard channel under neuroendoscopy

Abstract

The invention discloses a neuroendoscopic multidirectional adjustable hard channel, which comprises two hard channel plates, each hard channel plate is arranged in a semi-ring shape, the outer side of each hard channel plate is wrapped with an elastic wrapping layer, the side walls of the sides, close to each other, of the two elastic wrapping layers are both internally provided with a telescopic groove, and the telescopic grooves are arranged in the side walls of the sides, close to each other, of the two elastic wrapping layers. A plurality of telescopic grooves are formed in the hard channel plate, a movable plate is slidably connected to the interior of each telescopic groove, a connecting belt is arranged between every two corresponding movable plates, two transversely-arranged connecting springs are fixedly connected to the side walls of the sides, close to each other, of every two movable plates, and an expansion device is further arranged in the hard channel plate. The channel can be expanded, the brain tissue can be squeezed open, and after the brain tissue which is squeezed open is taken out from the channel, the brain tissue can return to the original position due to the elasticity of the brain tissue, so that damage to normal brain tissue of a patient is reduced to the maximum extent, and iatrogenic injury is reduced.

Description

technical field [0001] The invention relates to the medical field, in particular to a multi-directional adjustable hard channel under a neuroendoscope. Background technique [0002] When performing brain surgery, a puncture is usually required, that is, a small hole is opened in the brain to facilitate the surgical treatment of the patient. In order to prevent the brain tissue from blocking the patient, a hard channel will be used to insert the puncture The part is stuck to avoid the rebound of the brain tissue. [0003] When the existing hard channel is used, if its size is not enough, in order to facilitate the operation, it is usually punctured again to make a larger hole, and the brain tissue will be damaged again when the hole is opened, which is not conducive to the health of the patient. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when the hard channel is in use, if its size is not...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when the hard channel is in use, if its size is not enough, in order to facilitate the operation, it will usually be punctured again to open a larger hole, and after opening Holes will cause damage to the brain tissue again, which is not conducive to the health of the patient, and a multi-directional adjustable hard channel under the neuroendoscope is proposed.
