Further, the clamping groove for fixing the guide catheter has a convex cross section.
Furthermore, a clamping groove 8 matched with the nerve navigation piece is arranged on the outer side of the connecting hole of the nerve navigation piece.
Further, the end of the neuro-navigation piece is provided with a navigation slot 9.
Further, the navigation groove 9 of the end of the neuro-navigation piece is circular.
Further, the material of the flexible shaft fixer thimble 3 and the stainless steel screw is 304 stainless steel.
Further, the groove 10 on the upper surface of the other end of the thimble 3 is circular.
Compared with the prior art, the invention has the beneficial effects that: the invention has simple structure and reasonable design. The convex clamping groove is formed in the front side face of the end part of the short arm of the catheter connecting device body, so that the catheter connecting device is stably connected with a guide catheter. The outer side surface of the bending part of the short arm of the catheter connecting device body is provided with a nerve navigation part connecting hole, and the outer side of the connecting hole is provided with a clamping groove matched with the nerve navigation part, so that the nerve navigation part is detachably connected with the catheter connecting device body, and the nerve navigation part is removed from the catheter connecting device body when not needed, and the visual field of an operator is not influenced. The end part of the nerve navigation part is provided with a navigation groove, so that the guide catheter can be conveniently positioned. The device ensures the reliability of the craniocerebral operation to be greatly guaranteed.
