How realistic are the bone puncture and femoral vein puncture models in the simulation operation?

The realism of bone puncture and femoral vein puncture models in the simulation operation is very important for the training of medical students and clinical interns. These models not only provide learners with a safe and risk-free practice environment, but more importantly, they can highly simulate the real human anatomy and operation process, so that learners can feel similar experience in the simulation operation.

First, bone puncture models are typically made with environmentally friendly thermoplastic elastomeric mixed adhesive materials that have similar hardness and elasticity to real bone. Through the stainless steel mold by injection molding machine high temperature injection pressure, the model can present realistic bone morphology and anatomical structure. In the simulation of bone piercing operation, learners can clearly feel the texture and shape of bones, and then better understand and master the skills and methods of bone piercing.

Secondly, the femoral vein puncture model also has a high degree of imitation. These models are typically made of polymer materials that simulate real human skin and blood vessel systems. When simulating a femoral vein puncture, learners can feel the softness of the skin and the elasticity of the blood vessels, while the presence of simulated blood also adds more realism to the operation.

In addition, these models strive to be realistic in detail. For example, the anatomical markers in the bone puncture model (such as superior sternal notch, superior border of sternal stalk, anterior superior iliac spine, etc.) are clearly palpable for learners to perform puncture positioning. The vein direction and blood vessel depth in the femoral vein puncture model are also simulated according to the real situation, so that learners can find the puncture point more accurately in the operation.

In the simulation, learners can improve their piercing skills through repeated practice. These models allow learners to perform multiple piercing exercises at the same site without fear of harm to real patients. At the same time, due to the repairability of the model, learners can repair pinholes on the bone surface or skin after piercing for the next exercise.

In summary, bone puncture and femoral vein puncture models are highly realistic in simulation. They can not only simulate the real human anatomy and operating process, but also present a realistic operating experience in detail. These models provide a safe and effective practice platform for medical students and clinical interns to better master puncture skills and improve their clinical practice ability.
