目的 有效提升手术刀执刀训练实验教学效果和降低实验环境要求，改变现有实验教学手段单一的局面。 方法 提出了一种智能手术刀执刀训练教学指导模型的设计方法，并进行了2版的修正设计和实验。 结果 所设计的教学指导模型不但能模拟解剖工作场景，还具有手术刀执刀手法及动作的智能识别功能，可以感知握刀的手型、倾角、用力大小、入刀和出刀动作、行刀方向、速度、距离等。通过运用4种执刀法的训练预案，可实现手术刀执刀训练，交互式语音指导和训练成果评价的整个实验教学指导过程。 结论 教学指导模型可有效提升执刀训练教学的效果和效率，是一种值得推广的医学实验教具和训练设备。

Objective To effectively enhance the scalpel holding training, reduce the environmental requirements for training, and change the current experimental-teaching method . Methods We proposed a design method for intelligent scalpel holding training model, and corrected the design and experiment of version 2. Results The designed training model not only simulated anatomical work scene, but also intelligently recognized the hand-type of holding scalpel and the scalpel knife action. Concretely, the proposed model was able to apperceive the scalpel holding angle, force, insertion and evulsion, the direction, speed and distance of scalpel holding training. By using the four scalpel holding training plans, the proposed model completed the whole experimental teaching process, including scalpel holding training, interactive voice guidance and evaluation of the training result. Conclusion The experimental result shows that the teaching guidance model can greatly enhance the scalpel holding training teaching effect and efficiency, and is a worthy promotion of medical experimental teaching aids and training equipment.
