Description
Technical field
The utility model relates to medical instruments, more particularly, to a kind of dedicated ancon of nerve endoscope assistant.
Background technique
With the fast development of medical technology and surgical instrument manufacture craft, nerve endoscope has become neurosurgery
One of main instrument, be particularly suitable for skull base surgery, such as: pituitary tumor surgery, tubercle of sellae and Planum sphenoidal tumorectomy
Deng.Since nerve endoscope can provide illumination for art area, can approach observation and provide operative region clearly image in real time, make to perform the operation
It is more minimally invasive, safely, effectively, to be praised highly by the numerous neurosurgical doctors in the whole world.
Skull base surgery, especially intranasal-skull base surgery, by surgical procedure narrow space, it usually needs continuous adjustment mind
Angle and depth through scope.Although there is special nerve endoscope fixed arm at present, it is made of multi-joint, needs to adjust every time
It is fixed again after needing to unclamp multi-joint when the angle and depth of whole nerve endoscope, has seriously affected the progress of operation, extended hand
The time of art, and it is expensive.Patient generally requires a hand-held scope, the other hand operation as a result,.It is complicated, important in basis cranii
Institutional framework position, one-handed performance is often difficult to perform the operation.Therefore, an only people helps nerve endoscope, people's both hands hand
Art operation can make operation safety, effectively carry out.In art, assistant's hand nerve probe scope, rotation or forearm by wrist
Movement provide the illumination of art area and the image of clear, real-time, effective, each angle in time, effectively for patient, guarantee operation safety,
Successfully carry out.Neurosurgery, especially skull base surgery, usually take a long time, and assistant helps the arm of nerve endoscope long
Time is in vacant state, and arm muscles become stiff, bad stability, it is difficult to be precisely controlled the depth that nerve endoscope arrives at art area
Degree and angle, can also seriously affect the degree of safety and fluency of operation, to extend operating time.
How to enable assistant's arm muscles in long-time hand nerve probe scope not stiff, so as to be accurately controlled
The depth and angle of nerve endoscope provide the illumination of art area and the image of clear, real-time, effective, each angle for patient, are to ensure hand
The key of the safe and smooth progress of art.If one stable supporting point of ancon of assistant's hand nerve probe scope can be given in art,
Problem above will be readily solved.But the equipment or device of stable supporting point are specially provided for nerve endoscope assistant currently, still lacking
Tool.
Summary of the invention
