Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intraoperative guide plate structure, in particular to a foldable self-expanding intraoperative guide plate structure. BACKGROUND

[0002] In the field of surgical operation, the external contact guide plate is widely used in clinical scenes such as orthopedics and maxillofacial surgery due to its characteristics of directly adhering to the skin surface and assisting the precise positioning of surgical instruments. However, the traditional external contact guide plate is mostly made of rigid material and is integrally formed, which is fixed in structure and lacks flexibility. In actual use, it exposes many problems. On the one hand, its large size leads to inconvenience in storage and transportation, especially in emergency rescue or mobile medical scenes, making it difficult to respond quickly. On the other hand, due to the complex and variable morphology of the human skin surface, the rigid guide plate cannot closely fit the body surface profile of different patients, which is easy to produce gaps or displacement, resulting in positioning deviation of surgical instruments, affecting the accuracy and safety of the operation. In addition, during a long operation process, the continuous compression of the hard guide plate on the skin may cause local tissue ischemia, pressure sores and other complications, reducing the patient's comfort and postoperative recovery quality. At the same time, if the surgical plan needs to be adjusted according to real-time images during the operation, the traditional external contact guide plate cannot be conveniently repositioned or disassembled, limiting the flexibility and efficiency of the operation. With the development of medical technology towards minimally invasive and precision, as well as the continuous improvement of personalized medical needs, the development of a new type of external contact guide plate with foldable and self-expanding functions has become the key to solving the above problems.
