Described here is a rat headholding device intended for use in stereotaxic surgery. The assembly consists of a mouthpiece that accommodates the upper incisors and fits against the lateral and occlusive surfaces of the upper molars and of a contoured extension that is clamped down against the snout. To determine whether the apparatus could provide adequate stereotaxic support, we compared measures of skull displacement during surgery when using the "snoutclamp" and when using conventional earbars. Although the snoutclamp did not hold the head as rigidly as the earbar assembly did, the loss of accuracy was small. We judge that the snoutclamp can be used effectively as an alternative headholding device for many applications of stereotaxic surgery.
这里描述的是一种用于立体定向手术的大鼠头部固定装置。该组件包括一个容纳上门齿并贴合在上颌磨牙的侧面和咬合面的咬嘴，以及一个向下夹在口鼻部的异形延伸部分。为了确定该装置是否能提供足够的立体定向支撑，我们比较了在手术过程中使用“口鼻夹”和使用传统耳杆时颅骨位移的测量值。尽管口鼻夹不像耳杆组件那样牢固地固定头部，但精度损失很小。我们认为，口鼻夹可以有效地用作立体定向手术许多应用中的替代头部固定装置。
