Technology be robot brain's horseley-Clarke technique, establish brain coordinate system and direction finder be installed on skull, coordinate system is established, to brain
Portion's target structure is positioned, and surgical manipulator (such as microelectrode, damages needle, scalpel at biopsy needle) is imported target spot and is grasped
Make, at this time, it may be necessary to the two-way scalpel for disposably accurately cutting off nerve, current scalpel length is shorter, cannot
Meets the needs of some operations.This is in place of the deficiencies in the prior art.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of medical nerve surgical knife, convenient bidirectional it is primary
Property cutting nerve.
The utility model adopts the following technical solution realizes goal of the invention:
A kind of medical nerve surgical knife, including lever, it is characterized in that: cylinder is cased on the outside of the lever, it is described
One end of support frame is fixedly connected on the outside of cylinder, the other end of support frame as described above passes through cylinder one respectively and cylinder two is cut with scissors respectively
Connect one end of support plate two and support rod one, the other end of the support rod one and the support plate two passes through three He of cylinder respectively
Cylinder four is hinged in support plate one, and the support plate one is fixed in fixed plate, and set square is equipped on the upside of the fixed plate,
Blade is equipped on the downside of the fixed plate.
As further limiting for the technical program, it is characterized in that: the upper end of the lever is equipped with support rod three, the branch
The both ends of strut three pass through one end of six hinged support bar two of cylinder respectively, and the other end of the support rod two is cut with scissors by cylinder five
It connects in the support plate two.
Compared with prior art, the advantages and positive effects of the utility model are as follows: according to robot brain's horseley-Clarke technique,
After position is had good positioning, attending physician takes lever on the other hand, takes support frame on the other hand, pushes lever, drives support rod three and support rod
Two movement, to drive support plate two and support rod one to swing along cylinder four and cylinder three in succession, because of support plate two and branch
Strut one is hinged in support plate one, and support plate one is fixed in fixed plate, and the downside of fixed plate is equipped with blade, so with moving knife
Piece closure, cuts off nerve, hinged, the hinge of support rod two and support rod three of support plate two and support plate one and support frame
It connects, both contributes to the operation that attending physician performs the operation, flexible motion, to realize two-way disposable accurately general
The cutting of nerve, in addition, support rod two, support rod one and support plate two also increase the length of entire scalpel, so that blade
Inside of human body can be deep into be cut off.The utility model is easy to use, and structure is simple, in the operation for carrying out neurosurgery
When, it is safe and efficient.

Specific embodiment
With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this
The protection scope of utility model is not limited by the specific implementation.
As Figure 1-Figure 5, the utility model includes lever 11, and the outside of the lever 11 is cased with cylinder 10, the circle
The outside of cylinder 10 is fixedly connected with one end of support frame 8, and the other end of support frame as described above 8 passes through cylinder 1 and cylinder 2 12 respectively
It is respectively articulated with one end of support plate 26 and support rod 1, the other end of the support rod 1 and the support plate 26 leads to respectively
Being hinged in support plate 1 of cylinder 3 14 and cylinder 4 15 is crossed, the support plate 1 is fixed in fixed plate 2, the fixation
It is equipped with set square 1 on the upside of plate 2, is equipped with blade 3 on the downside of the fixed plate 2.
The upper end of the lever 11 is equipped with support rod 39, and it is hinged that the both ends of the support rod 39 pass through cylinder 6 17 respectively
The other end of one end of support rod 27, the support rod 27 is hinged in the support plate 26 by cylinder 5 16.
Utility model works process are as follows: according to robot brain's horseley-Clarke technique, after position is had good positioning, attending physician
Lever 11 is taken on the other hand, takes support frame 8 on the other hand, pushes lever 11, the movement of support rod 39 and support rod 27 is driven, thus in succession
Support plate 26 and support rod 1 is driven to swing along cylinder 4 15 and cylinder 3 14, because support plate 26 and support rod 1 are hinged
In support plate 1, support plate 1 is fixed in fixed plate 2, and the downside of fixed plate 2 is equipped with blade 3, so closing with cutting blade 3
