Abstract
The utility model belongs to the medical rongeur used for operation, in particular to a bone rongeur of sphenoidal sinus used in the operation on the sphenoidal sinus. The utility model mainly comprises a right and left rongeur body compising a handle arm and an operating arm and is characterized in that the right and left rongeur body is of the scissors shape like a gun and is provided with a pin shaft at the middle part, and the front end of the operating arm is provided with an upper and lower cutting blade nozzle in which a bone storing groove is arranged; the rear ends of the handle arm of the right and left rongeur body are provided with handle holes like scissors, and the included angle between the handle arm of the right and left rongeur body and the operating arm is an obtuse angle. The beneficial effect of the utility model is that the utility model can replace the bone chisel in the operation of the sphenoidal sinus and can not block the line of sight of the doctor and then help the doctor to open the front wall of the sphenoidal sinus quickly and accurately.
Description
Technical field
This utility model belongs to the medical operating pincers, relates in particular to the sphenoid punch that uses in a kind of trans-nasal-sphenoidal approach operation.
Background technology
The operation of saddle district space occupying lesion such as Pituitaryadenoma at present, the doctor takes single nostril through the sphenoid sinus approach operation of " windowing " usually.In operation process, need at first to chisel anterior sphenoidal wall with osteotome.When the doctor operates, can only observe anterior sphenoidal wall by nasal cavity, the visual field is very little, and the osteotome that stretches into nasal cavity also stops doctor's sight line, thicker because of the anterior sphenoidal wall sclerotin again, and it is protruding that the sphenoid sinus left and right sides forms the V-arrangement point, and the antetheca out-of-shape is slided when osteotome is opened the antetheca sclerotin easily, extremely unstable, cause operating accuracy poor, can not open anterior sphenoidal wall rapidly and accurately, operation efficient is low.At present, generally use a kind of sphenoid punch both at home and abroad, its structure is to be become by preceding cutter, back knife tackle, and preceding cutter is motionless, fully by pushing away before the cutter of back, operation place flat bone is squeezed when preceding cutter is worked with back cutter interlock.After this rongeur only is adapted at the anterior sphenoidal wall center line and is opened, sting, play the effect that enlarges the bone window except that the relatively thin sclerotin in both sides, and can not the true anterior sphenoidal wall of opening of replacement bone.In the trans-nasal-sphenoidal approach operation, demand developing the sphenoid punch that a kind of alternative osteotome also can be opened anterior sphenoidal wall rapidly and accurately urgently.
The utility model content
The purpose of this utility model provides in a kind of trans-nasal-sphenoidal approach operation and substitutes osteotome, and does not block the sphenoid punch that patient's sight line also can be opened anterior sphenoidal wall rapidly and accurately.
For realizing the purpose of this utility model, the technical scheme that is adopted is: a kind of sphenoid punch, mainly contain the left and right sides caliper that grips arm, working arm composition, it is characterized in that: described left and right sides caliper is the scissor of pistol shape, the middle part of left and right sides caliper working arm is provided with bearing pin, and the working arm front end is provided with occlusive blade opening up and down, is provided with bone storing groove in the occlusive blade opening, the gripping arm end of described left and right sides caliper is provided with scissor gripping hole, and the gripping arm and the angle between working arm of left and right sides caliper are the obtuse angle.
Described bone storing groove is for long semicircle.
After closing up, described working arm front end bite cutting edge is conical.
The beneficial effects of the utility model: it can substitute osteotome in the trans-nasal-sphenoidal approach operation process, and does not block doctor's sight line and can open anterior sphenoidal wall rapidly and accurately.
Further specify the purpose of this utility model, feature and advantage below in conjunction with accompanying drawing and preferred embodiment.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, a kind of sphenoid punch, mainly contain the left and right sides caliper 6,7 that grips arm 1, working arm 2 compositions, described left and right sides caliper 6,7 is the scissor of pistol shape, the middle part of left and right sides caliper working arm is provided with bearing pin 8, and working arm 2 front ends are provided with occlusive blade opening 3 up and down, are provided with bone storing groove 4 in the occlusive blade opening 3, the gripping arm end of described left and right sides caliper is provided with scissor gripping hole 5, and the gripping arm and the angle between working arm of left and right sides caliper are the obtuse angle.Described bone storing groove is for long semicircle.After closing up, described working arm front end bite cutting edge is conical.Grip arm during operation outside the operator visual field, working arm diameter 5mm, through the passage arrival anterior sphenoidal wall of the about 1.5cm of diameter, and the folding mode of employing shears, do not stop patient's sight line, the accuracy when therefore whole design has guaranteed operation.Working arm front end bite cutting edge adopts the interlock mode of common pliers, can utilize the protruding characteristics of anterior sphenoidal wall V-arrangement point when operation, stings except that the anterior sphenoidal wall sclerotin from left and right directions, therefore can not slide in operation, guarantees the stability of operation.The patient puts into the gripping hole that grips the arm end with thumb and middle finger, adopts the gripping mode of shears, has guaranteed the stability of gripping in operation and the facility of snap-action.The anterior sphenoidal wall sclerotin of stinging cutting-out can be stored in the interior bone storing groove of cutting edge.This utility model can substitute osteotome in the trans-nasal-sphenoidal approach operation process, and does not block doctor's sight line and can open anterior sphenoidal wall rapidly and accurately.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
