磁性压迫腹部大血管血流阻断系统的研制

The Development of the System of Blood Flow Block by Using Magnetic Compression Abdominal Large Vascular

磁性压迫腹部大血管血流阻断系统由体内磁阻断单元、体外电磁单元、非顺磁性手术器械组成。该系统在特制的手术床上预置体外电磁单元,当术中需要阻断腹主动脉或下腔静脉时,可将体内磁阻断单元直接置于拟阻断大血管的腹侧,此时体内外磁单元相吸可迅速、直接压迫拟阻断血管,关闭腹腔出血总"阀门"。该系统利用磁性材料非接触性吸力的特点,借助生物医学工程技术,能够实现腹部手术术中迅速控血,该方法直接压迫拟阻断血管,无需分离就能达到血管阻断目的。

A new system of blood flow block for control of bleeding in abdominal operation is composed of an abdominal magnetic blocking unit, an abdominal external electromagnet unit and other non-magnetic operation instrument. The abdominal external electromagnetic unit is placed in advance in the operation bed. The abdominal magnetic blocking unit can be placed directly on the ventral of the large vessels when need to blocking the abdominal large vessels during the operation. According to the non-contact suction characteristics of magnetic materials, the two magnetic units wil attract each other and compression the vessels. Using this system for vascular occlusion does not need clear exposure and without separating vessel. There is the advantage of rapid, accurate and reliable for the system.
