　　Objective: To explore the methods to prevent rabbit sarcoidosis and dilator displacement in deep fascia.

　　Method: 40 normal experimental rabbits were randomly divided into 2 groups, 20 experimental group and 20 control group. On the side of the back skin, the deep surface of the carnivore is separated from the incision, forming the implant cavity. Suture the hole and deep fascia intermittently with 3-0 silk thread and 50 mL kidney shape. Embedded with silicone rubber soft tissue expander. One week after the operation, a puncture machine was used to perform black stabs at four points around the dilator to mark the position of the dilator. The experimental group began to inject water two months after the operation until the total volume reached 140 mL, and the control group began to inject water until the total volume reached 140 mL one week after the operation. Observe and record complications, such as whether the experimental dilator and control dilator move during the infusion, whether the incision is split, whether the injection pot is turned over, and animal mortality.

　　Result: The rabbits in the experimental group did not experience the dilator shift, while the 4 rabbits in the control group survived the dilator shift. Comparing the displacement of dilators between the two groups, the difference was statistically significant (P0.05); at the same time, there was no statistical difference in the turnover rate, infection rate and animal mortality of the dilators between the two groups. P\→ 0.05)).

　　 Conclusion: A single intraluminal fixation and delayed dilation operation can effectively prevent the dilator from shifting between the rabbit sarcoidosis and the deep fascia, thereby effectively dilating.
