Description

Technical Field

The utility model relates to the technical field of medical operation training equipment, in particular to a cerebral hemorrhage operation training device for simulating intracerebral vascular hemorrhage.

Background technique

Cerebral hemorrhage is a common acute disease with a very high mortality and disability rate, and its surgical operation is complicated and time-consuming. Therefore, each hospital needs a large number of doctors who can perform cerebral hemorrhage surgery. It is particularly important to quickly train doctors who are competent for cerebral hemorrhage surgery. In the existing technology, a simulated brain model is often produced to train doctors who perform cerebral hemorrhage surgery. However, the existing brain models only include a skull model and a brain flower model and a blood clot model filled in the skull model. When using the above-mentioned brain model for training, doctors can only be trained on how to deal with blood clots. However, there are emergencies in cerebral hemorrhage surgery. For example, the responsible cerebral blood vessels are more likely to rupture and bleed again when clearing blood clots. This process is a dynamic process and requires timely and effective treatment. This is a major challenge for doctors without practical experience, and the success rate is often low. Therefore, in order to solve the above problems, a new type of cerebral hemorrhage surgery training device that simulates intracerebral vascular bleeding is urgently needed.
