Description

一种用于神经导航的无创头架 Non-invasive head frame for a neurological navigation

技术领域 FIELD

[0001]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。 [0001] The present invention relates to the technical field of medical devices, in particular, non-invasive neural headgear for navigation.

背景技术 Background technique

[0002]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。 [0002] The neuro-navigational system for providing surgical planning preoperative, intraoperative guidance of a surgical procedure precise positioning technology, it neuroimaging diagnostic techniques, stereotactic surgery and microsurgery by combining high-performance computer, a virtual patient skull within the three-dimensional structure, between the virtual and the actual digital imaging anatomy of the nervous system, using GPS positioning principle to establish dynamic links, real-time understanding of the relationship surgical operation site and surrounding vital structures, in order to achieve minimal surgical trauma obtain the removal of lesions purposes, and to maximize the retention of nerve function. 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。 The nervous system as a navigation aid locating medical equipment, doctors can provide real-time intraoperative information effectively make up for the shortcomings of traditional neurosurgery way to improve the quality of surgery. 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:(I)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迀延不愈,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 At present, there are commonly used in neurosurgery Gen. stud holder is fixed on the patient's head (e.g., German production DORO three stud holder), which is pierced by the stud scalp, embedded in the patient's head is fixed to the skull, such headstock good stability, good to meet the head position is fixed, but the following disadvantages: large (I) trauma, head frame is fixed at the head, three sharp stud requires perforation scalp, skull plate directly to muscle, is easy to hurt the scalp and muscles of blood vessels and nerves; (2) significant consequences, because the head was three nail trauma, leading to bleeding and puncture site after prolonged headache, pain in the scalp or scalp numbness, the pain and numbness of the scalp Gan often delay healing, so that doctors and patients considerable distress; (3) affect the appearance, when the forehead is fixed, tacks need to play in the forehead, with no hair covered here, it is often a nail hole in the forehead very prominent site , and sometimes accidentally because even cause greater sliding stud wounds required stitches, greatly affect the appearance; (4) Setup headgear complex, devices are required to check the performance before and after each use, if it is found by a long stud variant blunt or out 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。 Now barb other abnormal conditions will no longer use, the installation process with at least two people required to prevent pain, many patients require general anesthesia. 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。 In addition, three stud holder in use may also cause some complications, such as bleeding skull nail holes, wound infection; after the end of surgery, remove headgear clamping systems for air quickly from the skull nail hole penetrate into the vein to cause a risk of air embolism; for some patients, infants patient's skull itself is thin or not fully developed, and the skull itself due to cerebral intracranial lesions caused to become thinner patients may occur during brain surgery in the head frame clamping system some of the symptoms, such as meningitis, epidural hematoma, cerebrospinal fluid leakage, severe cases may even cause damage to the cerebral cortex. 图1为现有的三钉头架固定头烦情况。 1 where three trouble conventional stud frame fixed head.
