The invention relates to a comb-cutting type sunflower harvesting method and header. The Comb-cutting type sunflower harvesting method and header header comprises a rack, a comb-supporting type standing grain pulling mechanism, a translation mechanism, a lifting mechanism, a cutting mechanism and a conveying mechanism. The cutting mechanism is used for cutting off stalks of sunflowers. The comb-supporting type standing grain pulling mechanism is used for supporting sunflower discs of the sunflowers in good time and throwing plants to the conveying mechanism after the lower ends of the plants are cut off. The translation mechanism and the lifting mechanism are used for driving the comb-supporting type standing grain pulling mechanism to move in the horizontal direction and the vertical direction respectively. The functions of a divider are integrated by the comb-supporting type standing grain pulling mechanism, hitting of a standing grain wheel to the sunflower discs and damage caused by grain falling are greatly reduced, the position of the comb-supporting type standing grain pulling mechanism can be independently adjusted up and down or front and back, comb-supporting and cuttingactions are timely, effectively and stably completed in cooperation with the cutting mechanism, and therefore the header adapts to the differentiation of sunflower plant heights and sunflower disc distribution height ranges under the condition of different plots or varieties.

The invention relates to a surgical method for two-step excision of a patient side liver by a liver winding belt method under a complete laparoscope, which comprises the following steps that: (1) a patient undergoes complete laparoscopic surgery in a general anesthesia state, the liver winding belt method is used for ligating a portal vein branch of the to-be-excided patient side liver, meanwhile, a liver winding belt is used for tightening the connecting portion between the left liver and the right liver to block traffic blood flow between the to-be-excided patient side liver and the to-be-reserved half side liver, after an abdominal cavity drainage tube is reserved at the portal of the liver, the abdomen is closed, and the first operation is completed; (2) after the first operation, the patient gradually recovers diet and recures for 6-15 days, so that the volume of theto-be-reserved half side liveris increased to the expected residual liver volume which is 30-40% or above of the standard liver volume; and (3) after the volume of the to-be-reserved half side liverof the patient is increased to the expected residual liver volume, a second operation is performed, a complete laparoscopic operation under general anesthesia is performed to excide the half-side liver of the patient, and the patient recures until complete rehabilitation. The invention further discloses a pressure-adjustable liver tightening device special for the surgical method.
