[0002] With the development of society and the continuous advancement of medical technology, the treatment of childhood hemangioma has received more and more attention. Childhood hemangioma is a common childhood disease. Minimally invasive treatment has become one of the important means of treating childhood hemangioma due to its advantages of small trauma and quick recovery. In the minimally invasive treatment of childhood hemangioma, accurate drug injection is one of the key steps. By accurately injecting drugs into the site of hemangioma, the growth of hemangioma can be effectively inhibited, its regression can be promoted, adverse effects on children's bodies can be reduced, and the healthy growth of children can be ensured.

[0003] However, in the injection process of minimally invasive surgery for children's hemangiomas, doctors mainly rely on handheld syringes for injection operations. Due to the limited flexibility of hand operation, doctors' hands are prone to fatigue during long operations, which not only leads to a decrease in hand stability, but also makes it extremely difficult to adjust the angle of the syringe. In addition, the tense atmosphere of the surgical environment and the strict requirements for surgical accuracy make it difficult for doctors to accurately adjust the angle of the syringe under the influence of psychological pressure. In addition, children may have involuntary movements or body movements during surgery. In order to cope with these situations, doctors need to frequently adjust their hand posture and strength, which further increases the difficulty of adjusting the angle of the syringe.
