Tongue diagnosis assesses health status by observing tongue characteristics, and tongue segmentation, as a key step in intelligent tongue diagnosis, requires accurately separating the tongue body from the background to lay a foundation for subsequent feature extraction and health analysis. However, tongue segmentation currently faces two main challenges: data scarcity and the dependency of existing large segmentation models (such as the segment anything model) on manual prompts. To address these issues, this paper proposes a zero-shot multimodal segmentation method. This method combines the SAM model with multimodal prompt techniques and implemented in a two-stage framework: 1) initial segmentation and similarity clustering, where the SAM model generates initial segmentation results, followed by a similarity clustering decoder to filter out potentially effective segmentations; 2) refined segmentation, where a multimodal large language model analyzes tongue characteristics to generate precise point prompts, which are re-entered into the SAM model to achieve high-precision segmentation. This method enables intelligent segmentation with the SAM model in tongue diagnosis without the need for task-specific training or annotated data. Experimental results show that, compared to the original SAM model, this method improves the mIoU metric on three tongue diagnosis datasets by 27.3%, 18.2%, and 29.7%, respectively. %K 舌体分割， %K 零样本学习， %K 多模态大语言模型， %K 相似度聚类， %K 医学图像处理
