目的介绍一种显微手术用磁力底座拉钩及其在小鼠显微微创手术中的应用.方法磁力底座拉钩由纽扣磁铁、螺栓、螺母及牙用不锈钢丝弯折而成的拉钩组成.螺栓倒扣在磁铁上组成简易的磁力底座;不锈钢丝拉钩经两个螺母夹持固定在磁力底座的螺栓上,组成简易的磁力底座拉钩;纽扣磁铁具有较强的磁性,可使磁力底座拉钩吸附在不锈钢手术平台上.利用该拉钩辅助小鼠听泡暴露手术,并与传统常规拉钩进行比较.结果磁力底座拉钩可方便并有效牵引手术切口及肌肉等软组织,牵引方向、高度及强度均可调节,可获得良好的术窗暴露效果;与常规拉钩相比,可明显缩短手术切口,对肌肉及血管损伤少,减少意外出血机会.结论磁力底座拉钩可方便有效地暴露小鼠听泡显微手术窗口,具有微创特点,可作为一种简单有效且易于推广的小鼠显微手术器械.

Objective To introduce a novel retractor with magnetic fixator for mouse microsurgery. Methods The retractor was consisted of a magnet, a screw, two screw nuts and a hook made of dental stainless wire. The screw was connected to the magnet with magnetic force, and then was assembled to be a so-called magnetic fixator. The hook was clamped by two screw nuts on the screw, and these makes up of the retractor finally. Comparison has been done between the novel retractor and traditional retractor in the clinical application of the otocyst exposure. Results The retractor can quickly claw and retract massive tissue like muscles and vessels to the target position, thus, this properties would tend to offer a clear and expanded operative field. In addition, the height, orientation and strength of traction was all adjustable. By Comparison with tradition retractor, the operative incision can be shorten via the application of the retractor, also, it would reduce the trauma of muscles and vessels as well as the accidental rate of bleeding in the process of operation. Conclusions The retractor can offer a expanded operative field of the mouse otocyst conveniently. It could be a simple, powerful and minimal invasive tool for mouse microsurgery.
