吸引器头是手术中必需的器械。但普通吸引器头易被吸引物堵塞,而且使用不便。1991年1月～1992年9月,我们在肝胆外科手术中使用自己研制的囊式吸引器头50例。并与使用普通吸引器头50例对比,囊式吸引器头有不易堵塞、使用方便的优点。 1 囊式吸引器头结构 1990年我们在“流泥井”及“水漩涡流”原理的启发下,研制了囊式吸引器头。由咀管,囊及尾管3部分组成(见图)。 囊式吸引器头全长35cm,由无色透明玻璃构成,咀管长25cm,为一弯管。内径0.7cm。咀管口径0.5cm,咀管末端向下弯,插入吸引器头囊内。
Suction head is necessary for surgery equipment. However, the common suction head is easy to be blocked by the attraction and inconvenient to use. From January 1991 to September 1992, we used 50 capsules of our own aspiration head in hepatobiliary surgery. And compared with the use of ordinary suction head 50 cases, capsule suction head is not easy to plug, easy to use. 1 Capsule Suction Head Structure In 1990, inspired by the principle of “flow well” and “water vortex flow”, we developed a capsule suction head. By the tube, capsule and tail pipe 3 parts (see photo). Capsule suction head full length 35cm, made of colorless and transparent glass, pipe length 25cm, for a bend. Inside diameter 0.7cm. Tsui pipe diameter 0.5cm, Tsui tube end bent down, insert the suction head capsule.
