Description
Technical field
It is a kind of to be used for eye socket surgery scope navigation system specifically the present invention relates to technical field of medical instruments
Sclerite fixed traction tracer, the device are applied in eye socket surgical operation, can fix, draw and real-time location tracking weight
Want bone piece.
Background technology
Eye socket surgical endoscope navigation system is by medical image, Computer Image Processing, space orientation technique and scope
The surgical assistant system that the technology organic combinations such as imaging form, is innovation to eye socket surgically.It extends surgery
The limited field range of doctor, it is easy to patient to observe the institutional framework in deep, while monitors with early warning to avoid iatrogenic injury.
Its appearance breaches the boundary of traditional Orbital Surgery, promotes the change of Orbital Surgery theory so that eye socket surgical operation is imitated
Fruit has qualitative leap.
Navigation system uses infrared optical location technology more at present, is fixed on the anti-with infrared ray of skull by identification
The positioning frame of reference of source or emission source is penetrated, patient image is learned into the virtual coordinate system of data and the world coordinate system of patient's reality is done
Registration registration, by identifying operation tool and positioning the infrared emitting source on frame of reference or the position of reflection sources, follow the trail of and fixed
Position operation tool and the locus of patient, and it is included in navigation system display, surgical doctor is understood operation work
The information such as the position of tool, direction.
Positioning of the navigation system to locus at present is showed in the form of point-to-point, it is impossible to intuitively real in art
When show the locus of floating bone block, and must be touched in all directions by tracer probe bone piece could obtain indirectly it is some
The spatial positional information of point, and require that these point sets are connected into line in brain and are built into face by surgical doctor, thus it can just obtain
Know the locus of bone piece in art.This requires that surgical doctor possesses stronger spatial thinking ability, and is needed repeatedly in art
Bone piece or implant are detected in ground using tracer probe, and its is cumbersome, and display is not directly perceived, not only extends operating time, has
When even because causing reset effect undesirable the false judgment of locus.
The application for a patent for invention of Application No. 201410036033.1 discloses a kind of for eye socket surgery scope navigation system
The sclerite fixed traction tracer of system, including base element, gripping part, tracer part and fixing nut.But the device
All component combinations must be used together to reach tracer effect, and all component combinations together when, between each part
Relative position be all fixed, can not meet to draw any direction, limit the flexibility of operation.
Therefore, those skilled in the art is directed to developing a kind of sclerite fixed traction tracer dress for navigation system
