在神经外科部分肿瘤切除术中，需要牵拉肿瘤来分离肿瘤与其周围正常组织的粘连，以利手术切除肿瘤。而以往分离肿瘤与周围正常组织粘连时，多用脑压板推拉，带线牵拉肿瘤来完成牵拉分离步骤。上述两种牵拉效果差、易出血、分离视野小、步骤繁琐、甚至无法起到牵拉肿瘤的作用而 In the neurosurgery, some tumors need to be pulled to separate the adhesion of the tumor and its surrounding normal tissues in order to facilitate the surgical removal of the tumor. In the past, when isolated tumors adhered to surrounding normal tissues, they were often pushed and pulled using a brain pressure plate, and the tumor was pulled with a wire to complete the pulling and separation step. The above two kinds of pulling effects are poor, bleeding is easy, the field of separation is small, the procedures are tedious, and even the role of pulling tumors cannot be achieved.
