Craniosynostosis operation simulation system and method

Abstract

The invention discloses a craniosynostosis operation simulation system and method. The system comprises an operation table body and a stereoscopic skull model, a model fixing device is arranged on theupper portion of the operation table body, the stereoscopic skull model is connected with the model fixing device, an operation simulation layer is arranged inside the stereoscopic skull model and sequentially comprises a bone simulation layer, a bleeding point simulation layer and a simulation force feedback layer from outside to inside, the bleeding point simulation layer comprises a circulating liquid structure, and the simulation force feedback layer comprises a micro-sensor array for monitoring pressure applied to a cutting point. Personalized operation planning is provided for specificpatients, complicated skull reconstruction operation is visualized, doctors can perform preoperative planning and physical operation rehearsing, operation plans can be continuously adjusted and optimized, remodeled skulls are more attractive, and operation risks are reduced.

Description

technical field [0001] The invention relates to the technical field of surgery simulation, in particular to a craniosynostosis surgery simulation system and method thereof. Background technique [0002] Craniosynostosis is a collective term for a group of diseases caused by premature closure of cranial sutures in different parts, resulting in changes in the growth of the skull and affecting the normal development of the skull and brain. In some cases, there is enough space in the cranial cavity to accommodate the developing brain, but deformity of the skull and abnormal facial features result. In other cases, the narrowing of the cranial cavity cannot accommodate the normal development of the brain, which can lead to increased intracranial pressure, resulting in visual impairment, sleep disturbance, difficulty swallowing, or mental retardation and mental retardation. [0003] For all types of craniosynostosis, surgery is currently the only treatment. Through surgical interv...

Problems solved by technology

There are many problems with this conventional method: Some skull reconstructions do not necessarily require all the skulls to be cut and spliced, but only part of the skull to be cut, separated, and spliced, so it is difficult to design a plan before the operation; cranial reconstruction involves The positioning problem in three-dimensional space, it is difficult to fully consider the three-dimensional spatial relationship between the bone flaps in the process of skull reconstruction on the two-dimensional plane; due to the lack of effective means, the surgical plan cannot be effectively transferred to the implementation of the operation. The bone flaps that have been removed cannot be optimally utilized, and it is difficult to obtain an accurate splicing relationship between the bone flaps, so it is difficult to achieve the expected plastic results designed in the preoperative plan; because the surgical plan cannot be fully implemented during the operation, therefore During the operation, the protection of important positions and anatomical structures planned in the preoperative plan cannot be achieved; the operation cannot be meticulous and precise, resulting in excessive cutting of the skull, which has brought great harm to the bone flap. The injury is not easy to heal after operation, and there is a possibility of bleeding; the operation time is long, which affects the blood supply, blood pressure, and metabolism of the patient, increases the uncertain factors of the operation, and increases the risk of the operation

Some hospitals use virtual reality technology to simulate the surgical environment with the help of computer technology, and doctors use appropriate devices to perform interactive simulation operations on the three-dimensional virtual interface. However, the current technology has poor real-time performance, poor experience, and complex system design.
