Description
Technical field
The present invention relates to a kind of soft channels of nerve endoscope that skull fixed arm is adjusted with retractable scalp, belong to nerve
The surgical operating instrument technical field of surgery nerve endoscope platform.
Background technology
China has stepped into aging society at present, and hemorrhagic apoplexy patient about reaches 5,000,000 every year, mainly with hypertension
Based on cerebral hemorrhage and ventricular hemorrhage, the patient that hemotoncus is removed in operation is needed to account for about 20-30%, traditional operation mode is opens the big bone of cranium
Valve removes hemotoncus, haematoma cavity and ventricles of the brain catheter drainage, drawback：It opens cranium big bone flap removing hemotoncus and artificially aggravates cerebral injury
And complication is more；Preoperative positioning blind places pipe, may occur in which that puncture position deviates damage surrouding brain tissue, aggravates brain disorder,
Simple catheter drainage can make hemotoncus drainage insufficient, not up to shorten course of disease purpose.In addition, it swells in cranium brain deep tumor, the ventricles of the brain
In the diseases row traditional surgical procedures such as knurl and functionality, large-scale brain tissue exposure and operation passageway may occur in which artificial damage
Wound aggravates neurological dysfunction.
Carry out hypertensive cerebral hemorrhage removing art both at home and abroad at present, Intraventricular hematoma removes art, indoor tumor resection pushes away more
Extensively use disposable expander (disposable retractor).Its feature can accurately expose operative site to ventricles of the brain deep operation, behaviour
Make channel and be protected from the artificial secondary damage of brain tissue by expander.Operation is carried out compared to tradition using disposable expander
Operation method has more minimal invasive, while reduces flap bone flap exposure range, while shorten operating time, reduces postoperative infection machine
Rate, patient's recovery rehabilitation is fast, improves precision and the safety of operation.
With China's continuous research and development of nerve endoscope microinvasion platform in recent years, to the safety of nerve endoscope channel
Property, reliability, controllability requirement will be continuously improved.And the immature utilization for restricting this therapy always of endoscope passage and biography
It broadcasts.The patent of Publication No. CN107007333A discloses a kind of adjustable nerve endoscope channel of visualization, but the device can not
Operating walk way is fixed, and channel domestic demand places scope, aspirator and other operator tools simultaneously in surgical procedure；Such as
Fruit channel when more instruments operate in channel, is not only had an impact the stability of scope image without effectively fixed, heavier
Want be channel when more instruments operate in channel stability it is poor, it is further that channel generates hardness displacement in more instrumentations
Damage brain tissue；The optimum position that channel is arrived in surgical procedure, if without fixation, it will be because of the operation of instrument or with brain group
It knits displacement and shifts, adjusting channel position repeatedly also increases brain tissue impairment；Channel during endoscopic technic is rigid material, can not
Each visual field and work angle are more freely adjusted, if hardness compressing brain tissue is transferred to optimum field and work angle by force, just
It can rigid Displacement damage brain tissue.
