Description
Technical field
A kind of rongeur is the utility model is related to, particularly a kind of sphenoid punch.
Background technology
Pituitary operation in, generally through sphenoid sinus enter cut off, needed during this with sharp rongeur come
Sting the processus coracoideus except vomer make anterior sphenoidal wall exposure or with rongeur bite away sphenoid sinus interval with this fully to expand approach with
Lower wall before exposure ephippium.But the occlusion structure of existing sphenoid punch is generally in horizontally disposed with rongeur main body
, it is unfavorable for rongeur and gos deep into, field of view is smaller, and V-arrangement point is convex, and antetheca shape is not advised due to being formed at left and right sides of sphenoid sinus
Then, rongeur easily slides in occlusion, extremely unstable, causes manipulation accuracy not high.Meanwhile current rongeur can only be right
One direction is engaged, and doctor needs continuous adjusting position angle to be engaged the sphenoid sinus vomer of different zones in operation,
So not only increase the operation difficulty of doctor, can also reduce the efficiency of operation.Therefore, existing rongeur is unstable there is occlusion
Calmly, the problems such as accuracy is not high, operation difficulty is big and reduces procedure efficiency.
Utility model content
The purpose of this utility model is, there is provided a kind of sphenoid punch.It has the stability for improving rongeur occlusion
Precision with occlusion, the characteristics of reducing operation difficulty and improving procedure efficiency.
The technical solution of the utility model：Sphenoid punch, including the fixed handle and flexible handle being hinged, it is fixed
Handle upper end is provided with connecting rod, and interlinking lever end is provided with the fixed pliers head that bending is set, and fixed pliers head end is provided with the fixation of U-shape structure
Cutting edge, fixed pliers head upper surface are provided with T-slot, and T-slot is provided with one group of band joint and movable binding clip, and adjustable clamp cephalic par is provided with
The movable cutting edge corresponding with fixed cutting edge；The connecting rod upper surface is provided with the second T-slot, and the second T-slot is provided with push rod, pushed away
Bar one end is connected through bearing pin with joint, and the push rod other end is provided with and pushes away groove, pushes away the drive block for being provided with groove and being connected with flexible handle.
In foregoing sphenoid punch, inclined arrangement between the fixed cutting edge and fixed pliers head.
In foregoing sphenoid punch, the angle of bend between the fixed pliers head and connecting rod is 25-35 degree.
In foregoing sphenoid punch, the angle of bend between the fixed pliers head and connecting rod is 30 degree.
In foregoing sphenoid punch, the angle of bend between the fixed pliers head and connecting rod is 85-95 degree.
In foregoing sphenoid punch, the angle of bend between the fixed pliers head and connecting rod is 90 degree.
In foregoing sphenoid punch, the gag lever post of arcuate structure is provided with the inside of the fixed handle, gag lever post is hinged with
Motion bar, motion bar are fixed on the inside of flexible handle, and are provided with loose slot on the inside of flexible handle.
In foregoing sphenoid punch, the fixed handle is provided with bumping post and locking handwheel；Set on the flexible handle
There is screens bar, screens boom end is provided with the half slot to be fastened with bumping post.
Compared with prior art, the utility model is thus greatly square by the way that fixed pliers head is arranged into warp architecture
Rongeur go deep into, and occlusion structure and rongeur agent structure are not in the same plane, do not interfere with operator's observation
The visual field.Meanwhile by flexible handle, push rod, the cooperation with joint and movable binding clip, by setting fixed cutting edge and active blade
The occlusion of mouth so that rongeur is not easy to slide in occlusion, adds the occlusion stability of rongeur, improves the accurate of operation
Property, reduce the influence to patient；By the way that fixed cutting edge and movable cutting edge are arranged into U-shape structure, rongeur tool is so allowed for
There is an articulation port in 3 directions, what doctor only needed to finely tune rongeur in operation stings bone direction, greatly facilitates operation, carries
The efficiency and success rate of height operation.In summary, the utility model has the stability for improving rongeur occlusion and occlusion
Precision, reduce the characteristics of operation difficulty and raising procedure efficiency.
