Brain spatula for neurosurgery operation

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of teaching aids. Background technique [0002] When performing brain neurosurgery, it is necessary to use the brain compression plate to stretch the brain tissue to violently deep lesions, and provide a good view for neuroendoscopy and other surgical operations. It will still cause the risk of surgical instruments and other contact with brain tissue and cause damage to brain tissue, and when using a hard structure of the brain pressure plate, it is easy to cause damage to the brain tissue during use, while using a soft structure of the brain pressure plate When it is used, the soft structure cannot effectively support the brain tissue, so that the exposure of the surgical field of view is not thorough enough, which affects the operation process. Therefore, the traditional brain compression board has certain limitations in use. Contents of the invention [0003] The technical problem to be solved by the p...
