设计制作一种低成本、可靠性高的神经外科肿瘤标本留取装置。

运用纱布阻隔、负压抽吸的原理，设计制作了神经外科肿瘤标本留取装置。该装置包括壳体，壳体的底部中心处存在凸起，而底部的侧壁上设有出口，内部的中断设有过滤的装置，过滤装置设有漏网，漏网上存在接收片，壳体的顶部设有顶盖，顶盖上方存在进口。临床运用该装置进行术中肿瘤标本留取，取得很好的效果。

该神经外科肿瘤标本留取装置实验结果显示肿瘤标本留取满意，使用方便。

设计的神经外科肿瘤标本留取装置使用方便，结构简单、易存放、操作方便、成本低，具有实用价值。

To design a kind of lowcost, high reliability of tumor specimens return device for neurosurgery.

Using the principle of the gauze block and negative pressure suction, we design a kind of tumor specimens return device for neurosurgery. At the bottom of the device, it includes a shell which is raised at the bottom of the center, and an export equipped at the bottom of its′ side walls, filter device equipped in internal interrupt. The top of the shell has a roof, it is an import in roof. Clinical use of the device to return tumor specimens obtain a good effect.

The experimental result of tumor specimen return device shows that it's satisfactory, convenient to use.

The design is easy to use, simple structure, easy to store, convenient operation, low cost, and has a practical value.
