Abstract
The utility model relates to an acetabular bone circle ligament exsector, it includes application of force lever and vertical axis, its characteristics are: still include blade and bottom knife, last blade and bottom knife have the same size and structural blade or bottom knife and form by linking firmly afterbody as an organic whole and blade, the afterbody and the blade contained angle alpha that go up blade and bottom knife are 135-165, the blade front end sets up the through -hole, it is relative with lower blade cutting edge to go up the blade, the afterbody links firmly, the vertical axis circular bead is under, pass the through -hole of the blade front end setting of blade and bottom knife simultaneously, the higher authority of blade is placed in to application of force lever, the width articulates in the breach that the vertical axis set up for L's wall thickness. During the use, form the lever state with the upset of application of force lever earlier, again will the utility model discloses acetabular bone circle ligament both sides are placed in to the blade that last blade is relative with the bottom knife of exsector, hold between the fingers with the hand and press application of force lever and blade afterbody, can completely wipe out acetabular bone circle ligament.
Description
Technical field
This utility model relates to medical apparatus and instruments, is a kind of acetabular bone round ligament exsector.
Background technology
In current prosthetic replacement's operation, after femoral head dislocation, acetabular bone round ligament usually remains a part in acetabular bone because tearing, usually excise with routine operation cutter.Because of residual acetabular bone round ligament be present in acetabular bone recessed in, visual area is limited in scope, angle is not good, sometimes in order to excise residual acetabular bone round ligament completely, need lengthen the edge of a knife and expand visual area, or tractive soft tissue excises with strength, both time-consuming, effort, lengthen operating time, again easily because increase knife edge length or excessively tractive soft tissue make patient recovery times extend, increase misery and the financial burden of patient, even can excise incomplete.
Summary of the invention
Technical problem to be solved in the utility model is: the shortcoming overcoming prior art, there is provided that a kind of structure is simple, practical and convenient, time saving and energy saving, low cost, high efficiency acetabular bone round ligament exsector, acetabular bone round ligament can be excised completely, avoid increasing knife edge length or excessive tractive soft tissue, reduce patient suffering and financial burden.
The scheme of this utility model technical solution problem is: a kind of acetabular bone round ligament exsector, it comprises force lever and vertical pivot, described force lever is long-armed by what be fixed with one, galianconism and fulcrum composition, long-armed and galianconism is fixed with one with obtuse angle, galianconism arranges a rectangular through-hole, galianconism termination and rectangular through-hole mouth limit have the wall thickness that width is L, on long-armed, long-armed and junction that is galianconism arranges convex outside fulcrum, described vertical pivot one end arranges shoulder, the other end arranges the breach of inclination, it is characterized in that: also comprise top cutter and bottom knife, described top cutter and bottom knife have identical size and structure, its structure is: top cutter and bottom knife are made up of afterbody and blade, the angle α of afterbody and blade is 135 ° ~ 165 °, blade front end arranges through hole, top cutter is relative with bottom knife cutting edge, afterbody is connected, vertical pivot shoulder under, the through hole that the blade front end simultaneously passing top cutter and bottom knife is arranged, force lever is placed in above top cutter, width is that the wall thickness of L is articulated in the breach of vertical pivot setting.
This utility model acetabular bone round ligament exsector, its blade termination arrange convex outside curved edge can stretch into acetabular bone recessed in wipe out acetabular bone round ligament, the cutting edge and the blade structure that are similar to " nail clipper " completely can either wipe out acetabular bone round ligament, visual area or tractive soft tissue with strength need not be expanded again, reduce patient suffering and financial burden.During use, the lever that first will exert a force upset forms lever state, then cutting edge relative with bottom knife for the top cutter of this utility model exsector is placed in acetabular bone round ligament both sides, pinches pressure force lever and blade afterbody with hands, completely can wipe out acetabular bone round ligament.There is the advantage that structure is simple, practical and convenient, time saving and energy saving, low cost, result of use are good.
Accompanying drawing explanation
Fig. 1 is the main structure schematic diagram of this utility model acetabular bone round ligament exsector;
Fig. 2 is the schematic top plan view of Fig. 1;
Fig. 3 is the structural representation of embodiment.
In figure: 1 top cutter, 2 bottom knife, 3 force levers, 4 fulcrums, 5 vertical pivots, 6 cutting edges, 7 galianconism, 8 is long-armed, 9 blades, 10 afterbodys.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated.
With reference to Fig. 1 ~ Fig. 3, a kind of acetabular bone round ligament of this utility model exsector, it comprises force lever 3 and vertical pivot 5, described force lever 3 is by be fixed with one long-armed 8, galianconism 7 and fulcrum 4 form, long-armed 8 and galianconism 7 be fixed with one with obtuse angle, galianconism 7 arranges a rectangular through-hole, galianconism 7 termination and rectangular through-hole mouth limit have the wall thickness that width is L, on long-armed 8, long-armed 8 and the junction of galianconism 7 convex outside fulcrum 4 is set, described vertical pivot 5 one end arranges shoulder, the other end arranges the breach of inclination, , also comprise top cutter 1 and bottom knife 2, described top cutter 1 and bottom knife 2 have identical size and structure, its structure is: top cutter 1 and bottom knife 2 are made up of afterbody 10 and blade 9, the angle α of afterbody 10 and blade 9 is 135 ° ~ 165 °, blade 9 front end arranges through hole, top cutter 1 is relative with bottom knife 2 cutting edge 6, afterbody 10 is connected, vertical pivot 5 shoulder under, the through hole that blade 9 front end simultaneously passing top cutter 1 and bottom knife 2 is arranged, force lever 3 is placed in above top cutter 1, width is that the wall thickness of L is articulated in the breach of vertical pivot 5 setting.This utility model adopts prior art manufacture.
When the present embodiment uses, first force lever 3 is overturn and form lever state, again cutting edge 6 relative with bottom knife 2 for the top cutter 1 of this utility model exsector is placed in acetabular bone round ligament both sides, pinches the afterbody 10 of pressure force lever 3 and blade 9 with hands, completely can wipe out acetabular bone round ligament.
This utility model is not limited to this detailed description of the invention, and to those skilled in the art, simple copy and improvement without creative work all belong to the scope that this utility model claim is protected.
