Description

Contactless positioning auxiliary device for intracranial hematoma microscopic wound dissection
Technical field
This utility model belongs to technical field of medical equipment, is specifically related to a kind of contactless positioning auxiliary device for intracranial hematoma microscopic wound dissection.
Background technology
Cerebral hemorrhage (intracerebral Hemorrhage, ICH) refer to the hematostaxis in non-traumatic cerebral essence.The overwhelming majority is that the arteriolosclerotic angiorrhexis of hypertension causes.Hypertensive patient there are about the probability of 1/3 and cerebral hemorrhage, the patients with cerebral hemorrhage of about 95% can be occurred to have hypertension.Cerebral hemorrhage is that the acute cerebrovascular disease that middle-aged and elderly people is common, case fatality rate and disability rate are the highest.According to the statistics of European Stroke association, 1 year survival rate of patients with cerebral hemorrhage is only 46% [ Steiner T, Al-Shahi Salman R, Beer R, Christensen H, Cordonnier C, Csiba L, et aL. European Stroke Organisation (ESO) guidelines for the management of spontaneous intracerebral Hemorrhage [J]. Int J Stroke, 2014,9:840-855 ].Chinese society is just stepping into aging, and the sickness rate of cerebral hemorrhage also can rise therewith, and 2014 Annual occurence rates have been up to 100.9/ ten thousand people, brings white elephant to society and family.Hypertensive cerebral hemorrhage site distribution situation is: 70% occurs in the shell core of Basal ganglia and capsula interna district, and bleeding profusely can ventricular extension and subarachnoid space;Cerebral lobe, brain stem and cerebellar hemorrhage respectively account for 10%.The Therapeutic Method of cerebral hemorrhage mainly has internal medicine conservative treatment and surgery to open cranium hematoma clearance.In recent years Microlesion intracranial hematoma dissection because of its expense low, easy and simple to handle, the advantages such as operation wound is little [Li Ge, Shen Ming. bone window craniotomy operation evacuation of hematoma treats the Comparison of therapeutic [J] of hypertensive cerebral hemorrhage with microtrauma puncture evacuation of hematoma. nerve injury and reconstruction, 2014, 9:160, 171.], it is made to have also been obtained relatively broad application in clinic, and achieve good clinical effectiveness [Huang Yuanzhi, Hu Cuizhu, yellow published article. the application [J] in hypertensive cerebral hemorrhage of the microtrauma puncture evacuation of intracranial hematoma. Wicresoft's medical science, 2013, 8:366-367.].
Microlesion intracranial hematoma dissection is divided into hard passage and the main art formula of two kinds of soft passage.The former is represented as " WTF-1 type intracranial hematoma Wicresoft clearance technique ", it is directly to drill through head with a draw point carrying drill bit to arrive hematoma, suction and treatment drain hematoma [Zhang Qingzhong, Wen Chuanzhi, Jiang Ming, Jia Bin. the clinical practice [J] of WTF-1 type intracranial hematoma directional puncture apparatus. apoplexy and sacred disease magazine 2006, 3: 362];And the latter is first sphenotresia, again by cranium hole flexible pipe puncture hematoma [Sun Guiliang, Bai Chunyan, Sun Zhongbo. soft passage microtrauma puncture evacuation of hematoma treatment acute cerebral hemorrhage Clinical efficacy [J]. contemporary medical science, 2014,20(20): 111-112.].
The clinical technology threshold of Microlesion intracranial hematoma dissection is low, is the medical and health appropriate technology being suitable for and having promoted in basic unit, but hematoma is positioned at intracranial, and naked eyes can not directly be observed, and conventional Head And Face physiology body surface marking cannot meet the requirement of precisely puncture.The softest passage or hard access penetrations art, hematoma location, inserting needle path are often by head CT, square auxiliary positioning, rely primarily on naked eyes and clinical experience completes, occur puncturing error and cause puncturing effect and reduce, even result in the complication such as normal cerebral tissue's major injury.The more method of Clinical practice is to simulate head median sagittal plane with flat board with head front, and naked eyes judge the vertical relation of puncture needle and this face, and puncture needle and CT examination collimation relation of plane, and method is coarse, and shortage is scientific.The intracranial hematoma microtrauma puncture clearance technique specification of 2014 editions describes the technical method using the auxiliary locator of external fixer pattern to increase positioning accurate accuracy, but complex operation step, equipment is complicated, technical threshold is high, and contact position finder exists the risk increasing intracranial infection rate, in actual clinical, utilization rate is the highest.
