Description

Collimation guide instrument

Technical Field

The application belongs to the technical field of operation navigators, and particularly relates to a collimation guide instrument.

Background

Cerebral hemorrhage (cerebral hemorrhage) refers to hemorrhage caused by non-traumatic rupture of blood vessels in brain parenchyma, and accounts for 20% -30% of all cerebral apoplexy, and the death rate in acute stage is 30% -40%. The cause of the disease is mainly related to the pathological changes of the cerebral vessels, namely closely related to hyperlipidemia, diabetes, hypertension, vascular aging, smoking and the like. Patients with cerebral hemorrhage often suffer from sudden onset of diseases due to emotional agitation and strenuous exertion, the early mortality rate is very high, and most survivors have different degrees of sequelae such as dyskinesia, cognitive impairment, speech dysphagia and the like.

Cerebral hemorrhage is common hemorrhagic stroke, has high disability rate and mortality, is particularly most dangerous for cerebral hemorrhage, accounts for about 10 percent of clinical cerebral hemorrhage cases, has low morbidity, but has acute onset of cerebral hemorrhage, serious illness and poorer prognosis, and is the disease with the highest fatality rate and the worst prognosis in all cerebral apoplexy. The cerebral hemorrhage accounts for 5.0-13.4% of cerebral hemorrhage, and is usually caused by rupture of the artery passing through the basilar artery supplying the cerebral bridge. The death rate of patients with 10ml of cerebral hemorrhage is 100%; in the past, brainstem hemorrhage is not suitable for surgery, but with the development of minimally invasive technology, particularly the application of stereotactic accurate positioning in clinic, the surgery has obviously benefited patients with brainstem hemorrhage, the survival rate is obviously improved, and even a part of patients are conscious. Hemorrhage puncture drainage and intracerebral lesion (brain tumor, inflammation, infarction and the like) disease detection of important structures such as brainstem and the like: according to the concept of precise neurosurgery, the damage to the surrounding brain tissue is minimized, intracerebral hematoma such as brainstem and the like is led out to the maximum extent, and intracerebral lesion tissues are taken out accurately for definite diagnosis, so that the method has important significance for improving the curative effect of operations on important functional areas of the brain, reducing complications and maintaining the life quality of patients.

Because the tumor in the brain is not directly visible, the three-dimensional stereotaxic apparatus is usually adopted for directional treatment, and the domestic three-dimensional stereotaxic apparatus is mainly used in provincial and municipal major hospitals and cannot be widely popularized in local hospitals at present due to the fact that the price is high and the three-dimensional stereotaxic apparatus is mainly imported. Moreover, the three-dimensional orientation instrument is complex to operate, and has high puncture abrasion, maintenance and use costs.
