Description
技术领域technical field
本发明涉及医疗器械技术领域，具体地说，是一种用于神经导航的无创头架。The invention relates to the technical field of medical instruments, in particular to a non-invasive head frame for neuronavigation.
背景技术Background technique
神经导航系统一种提供术前制定手术方案、术中指导手术操作的精确定位技术，它将神经影像诊断技术、立体定向外科和显微外科通过高性能计算机结合起来，虚拟出病人颅内的三维结构，在虚拟的数字化影像与实际神经系统解剖结构之间，运用GPS定位原理建立起动态的联系，实时了解手术操作部位与周围重要结构的关系，达到以最小手术损伤获得切除病灶的目的，并且能够最大限度保留神经功能。神经导航系统作为一种医学辅助定位设备，能够为医生提供实时的术中信息，有效弥补了传统神经外科手术方式的不足，提高了手术质量。目前，神经外科中常用有创三钉头架对患者头部进行固定(如德国生产的DORO三钉头架)，其通过将头钉刺穿头皮，嵌于颅骨上固定患者头部，该类头架稳定性好，可以满足良好的头位固定，但其存在如下缺点：(1)创伤大，头架在固定头部时，三个尖锐头钉需要穿破头皮、肌肉直达颅骨外板，很容易伤到头皮和肌肉的血管和神经；(2)后遗症明显，由于头部遭三钉创伤，导致穿刺点出血和术后长时间的头痛、头皮痛或者头皮麻木，这种疼痛和头皮麻木常常迁延不愈，令医患相当苦恼；(3)影响美观，额部被固定时，头钉需要打在前额部，此处没有头发覆盖，往往是一个钉眼在额部非常显眼的部位，而且有时由于不慎，甚至头钉滑动造成较大的伤口，需要缝合，大大影响美观；(4)头架安装程序复杂，每次使用前后都需检查设备性能，一旦发现头钉用久变钝或出现倒钩等异常情况便不可再使用，安装过程至少需两人配合，为防止疼痛，病人多需全麻。此外，三钉头架在使用中还有可能造成一些并发症的发生，如颅骨钉孔出血、伤口感染；在手术结束以后，卸掉头架夹持系统的同时，空气会迅速从颅骨钉孔处渗入到静脉血管，以导致发生空气栓塞的危险；对于有些患者，本身的颅骨较薄或是未完全发育的婴幼儿患者，还有本身因脑颅内发生病变而导致的颅骨变得比较薄的患者，在进行颅脑手术中头架夹持系统时可能会出现一些症状，比如脑膜炎、硬膜外血肿、脑脊液漏等危险，严重者甚至会导致大脑皮质损伤。图1为现有的三钉头架固定头颅情况。The neuronavigation system is a precise positioning technology that provides preoperative planning and intraoperative guidance for surgical operations. It combines neuroimaging diagnosis technology, stereotaxic surgery and microsurgery through high-performance computers to virtualize the three-dimensional intracranial of the patient. Structure, between the virtual digital image and the actual anatomical structure of the nervous system, use the GPS positioning principle to establish a dynamic connection, understand the relationship between the surgical operation site and the surrounding important structures in real time, and achieve the purpose of resecting the lesion with minimal surgical damage, and Can preserve neurological function as much as possible. As a medical auxiliary positioning device, the neuronavigation system can provide doctors with real-time intraoperative information, effectively make up for the shortcomings of traditional neurosurgery methods, and improve the quality of surgery. At present, in neurosurgery, an invasive three-nail head frame is commonly used to fix the patient's head (such as the DORO three-nail head frame produced in Germany), which pierces the scalp with the head nail and inserts it into the skull to fix the patient's head. The head frame has good stability and can satisfy good head fixation, but it has the following disadvantages: (1) The trauma is large. When the head frame fixes the head, three sharp nails need to penetrate the scalp and muscles to reach the outer plate of the skull. It is easy to injure the blood vessels and nerves of the scalp and muscles; (2) the sequelae are obvious, because the head is traumatized by three nails, resulting in bleeding at the puncture point and long-term postoperative headache, scalp pain or scalp numbness, this pain and scalp numbness (3) It affects the appearance. When the forehead is fixed, the head nail needs to be hit on the forehead. There is no hair covering here, and it is often a nail hole in a very conspicuous part of the forehead. And sometimes due to carelessness, even the head nails slide to cause large wounds, which need to be sutured, which greatly affects the appearance; (4) The installation procedure of the head frame is complicated, and the performance of the equipment needs to be checked before and after each use. Once the head nails are found to be blunt after a long time Or it can no longer be used if abnormal conditions such as barbs appear. At least two people are required to cooperate during the installation process. To prevent pain, patients often need general anesthesia. In addition, the use of the three-nail head frame may cause some complications, such as bleeding from the nail hole and wound infection; after the operation, when the head frame clamping system is removed, the air will quickly flow from the nail hole. Infiltrate into veins and blood vessels to cause the risk of air embolism; for some patients, infants and young children with thin skulls or underdeveloped skulls, and thinner skulls due to intracranial lesions Patients may experience some symptoms during the head frame clamping system in craniocerebral surgery, such as meningitis, epidural hematoma, cerebrospinal fluid leakage and other dangers, and severe cases may even lead to cerebral cortex damage. Fig. 1 is the situation of fixing the skull with the existing three-nail head frame.
