在各种外科手术中，出血和止血伴随整个手术过程，特别是手术渗血是外科的一大难题。以往外科常用的电凝、缝扎、压迫、凝血酶等止血技术，都存在着不同的局限性或副作用。以后研制的用于止血的生物蛋白胶，由于其制备需要以人血作为原料，所以成本昂贵，而且易造成血液传播性 In various surgical procedures, bleeding and hemostasis are associated with the entire surgical procedure. In particular, surgical oozing is a major surgical problem. In the past, surgical coagulation, suturing, compression, and thrombin, which are commonly used in surgery, have different limitations or side effects. Since the preparation of biological protein gel for hemostasis requires the use of human blood as a raw material, it is expensive and easily causes blood transmission.
