Abstract

The invention discloses a portable positioning device for intracerebral cathetering in neurosurgery. In cerebral hemorrhage or other brain diseases, the surgery application range of intracerebral cathetering is wide. Most of diseases of people suffering from the brain diseases are sudden onset; in the emergency surgery, the lesions are roughly positioned according to a preoperative computed tomography (CT) film under the general condition, free-hand puncturing is performed, and the cathetering path, direction and depth cannot be accurately controlled. The positioning device can find the level reached by cathetering through CT according to the principle that distances between all points on a spherical surface and a sphere center are equal, and the position of a catheter to be placed in the brain is adjusted to the angle that the sphere center of the positioning device and the puncturing direction can be changed front and back and left and right, and the cathetering depth is the radius of the sphere, so that the device can accurately reach the puncturing point. The positioning device is convenient to operate in intracerebral cathetering surgery such as intracranial hematoma puncturing, ventricular puncturing, and brain abscess puncturing, and can position the lesions accurately, and improve the achievement ratio of surgery. The portable positioning device is convenient to operate and practical in the encephalic cathetering in brain surgery and has wide popularization and application prospect.

Description

便携式脑内置管定位器 Brain built portable locator tube

技术领域 FIELD

[0001] 本发明是属于脑外科脑内置管手术时的定位仪器,在脑内置管手术时方便、实用、精准。 [0001] The present invention belongs to the positioning instrument during brain surgery, cerebral vascular surgery built, the built-in cerebral vascular surgery convenient, practical, precise. 属于医疗器械领域。 Belonging to the field of medical devices.

背景技术 Background technique

[0002] 脑内置管术是脑外科常用的手术方式,常用于脑出血,脑室出血,脑脓肿等疾病。 [0002] Cerebral built catheterization is commonly used surgical brain surgery, commonly used in cerebral hemorrhage, intraventricular hemorrhage, brain abscess and other diseases. 此类病人一般为急诊病人,病情为重,临床一般情况下根据术前CT片及患者的体表标志,进行粗略定位,徒手穿刺,置管路径、置管的方向及深度不能精确控制;尤其是头皮穿刺点与脑内置管位置不在同一CT扫描层面时(比如侧脑室穿刺),置管需要与颅骨形成一定角度时,往往置管位置欠佳,有时需根据临床经验,多次调整穿刺置管,这样往往造成了不必要的脑组织损伤。 Such patients generally emergency patients, the disease is severe, according to the general clinical preoperative CT scan and landmarks of the patient, for coarse positioning, puncture hand, catheterization path, the direction and the depth of the catheter can not be accurately controlled; in particular, when the scalp is not the same puncture and brain CT scan dimensions Drainage and location (such as the lateral ventricle puncture), catheter requires a certain angle with the skull, the catheter position is often poor, sometimes required based on clinical experience, several adjustments puncture pipe, which often resulted in unnecessary brain tissue damage. 给患者预后造成不可挽回的损伤。 Prognosis irreparable damage to the patient. 为了解决快速、精准、方便的穿刺置管手术,我们研制了此定位器。 In order to address the rapid, accurate and convenient catheterization surgery, we developed this locator.

[0003]目前,临床上脑外科置管手术的定位方法:①侧脑室置管:一般冠状缝前2cm中线旁开2.5cm处钻孔,置管时方向为同侧内目此与双侧外耳道的连线的交点,置管深度5-8cm,不同人群根据经验给予调整脑出血血肿腔穿刺术:一般在CT扫描同一层面穿刺时,根据CT扫描可以确定头皮穿刺点及置管深度,但有时由于钻孔移位可能导致穿刺不准;有时为了避开颅内重要功能区,头皮穿刺点与颅内置管位置不在同一CT扫描平面时,或者置管需要一定角度时,穿刺置管往往是在测量加经验下进行,穿刺置管精准性没有保障,效果欠佳;③脑立体定位穿刺:此手术需术前先戴头架,然后在CT室定位扫描后再穿刺置管,虽然手术定位准确,但手术过程繁琐,时间较长,不适宜于病情危急,意识不清,烦躁的患者。 [0003] Currently, clinical method of positioning neurosurgical catheter procedures: ① the lateral ventricle catheter: General front coronal suture adjacent the midline 2cm 2.5cm drilling, when the direction of the catheter and ipsilateral this purpose bilateral external auditory canal intersection connection, the depth of 5-8cm catheter, adjusting them to different populations cavity of intracerebral hemorrhage puncture experience: CT scan of the same general level puncturing, the puncture point can be determined and the scalp depth catheter according to CT scan, but sometimes Since the borehole may lead to displacement of the puncture allowed; intracranial sometimes important functional areas in order to avoid, when scalp and intracranial catheter puncture position is not in the same plane CT scan, or catheterization requires a certain angle, often in catheterization plus experience for the measurement, precision catheterization no protection is ineffective; ③ brain biopsy in: this procedure prior to wear headgear preoperative required, then CT scanning chamber positioned after the puncture, although the accurate positioning operation but surgical procedures cumbersome, long time, not suitable for critical illness, confusion, irritability patients. 但临床上大部分置管患者为脑出血患者,病情危重,意识不清,躁动,不宜立体定向穿刺,而需要方便、快捷、准确的定位器,此定位器正好解决了这一难题,为脑出血等急诊患者置管手术提供了保障。 But clinically most catheterization in patients with cerebral hemorrhage, in critical condition, confusion, agitation, not stereotactic puncture and need convenient, fast and accurate locators, this locator is just to solve this problem, the brain emergency surgery in patients with bleeding catheter to provide a guarantee. 可以大大提高手术成功率。 Can greatly improve the success rate.
