Brain spatula for neurosurgery operation
The invention discloses a brain spatula for neurosurgery operation, and relates to the technical field of surgical instruments. The brain spatula comprises an annular flexible shell; the interior of the shell is of a cavity structure; the cavity is filled with photosensitive resin; a coloring agent is mixed in the photosensitive resin; in the cavity structure, flexible light guide pipes are distributed on the side wall of an inner ring of the shell in a threaded mode; injectors and aspirators are distributed at one end of the shell in the circumferential direction in an array mode; and the injector is filled with a cosolvent. The brain spatula has the beneficial effects that after the shell is placed in a proper position, light rays are conducted along the spirally-distributed light guide pipes, so that the photosensitive resin on the peripheral side of the light guide pipes is cured to support the shell to form a surgical operation channel, and the contact with brain tissues during surgical operation is avoided; the photosensitive resin in other positions is kept in a fluid state, so that the outer wall of the shell is kept flexible to be in contact with brain tissues, and the damage to the brain tissues is avoided; and after the use, the photosensitive resin is extracted to keep a flexible structure and is taken out, and the use is flexible, safe and convenient.
