Abstract
The invention provides a fixing device for self-tapping screws fo surgery. The fixing device can be used for skull connecting plate fixation and skull repairing titanium plate fixation after craniotomy, skull drilling surgery and cranioplasty of neurosurgery and can also be applied to the field involving bone fixation and repairing, such as dentofacial surgery, cardiothoracic surgery and orthopaedics. The fixing device is simple and convenient to use, can consistently making a screw be perpendicular to a bone surface during application, and is adaptive to various bone connecting plates and surgical repairing materials.
Description
Technical field
The present invention relates to one, the fixing device of surgery screw, it belongs to surgery bone even
The technical field that contact pin or repair materials are fixed.
Background technology
Relate to bone fix and the field repaired include neurosurgery, decorative sursery, cardiothoracic surgery,
Orthopaedics etc., such as neurosurgery open cranium, sphenotresia, cranioplasty, all can relate to art
Rear skull connects sheet to be fixed, and skull repairing titanium plate is fixing.Such as, decorative sursery wounded patient
Need to repair maxillofacial bone bone and profile, relate to repair materials, such as fixing of titanium alloy sheet, breast
Cardiac Surgery Thorax operration chest rib is also received needs connection sheet to fix.The operation of orthopaedics majority all refers to art
Rear bone is fixed and reparation problem, and the major way that current bone is fixed still connects for application titanium alloy bone
Plate repaired by sheet or moulding titanium alloy, and applies self-tapping screw nail to be fixed in inside bone.
Now, bone screws manufacturing enterprise both domestic and external mainly by screw bulk storage, and
Put into a box when needed after aseptic process or direct scattered state is placed down in operating-table
Upper in case applying, fetch loaded down with trivial details and be difficult to operate, increase nurse and working doctor amount, and every time
Application uses hand screwdriver to be pierced in bone by screw, but due to surgery screw, especially
Neurosurgery and face amount surgery, screw small volume (less than surgical aspirator bore),
Quality is relatively light, easily comes off in bacteria district or is attracted device suction by mistake, then largely effecting on operation
Process.And pungent DIS of such as Switzerland of main overseas enterprise, although apply a plastic stent
Screw is stored respectively, but need nonetheless remain for breaking outside plastic stent into two with one's hands when application, then take
Go out screw, and apply hand screwdriver that screw is pierced skull, when operation application screw
When quantity is more very inconvenient, and screw cannot be avoided to be attracted device and to inhale by mistake.
Summary of the invention
For the problems referred to above of the prior art, it is an object of the present invention to provide one
Plant and be easy to the storage of surgery screw, application, it is to avoid nail is attracted device and inhales by mistake and surprisingly come off,
Simplify the device of operation technique flow process.
For realizing this purpose, the present invention provides the fixing device of a kind of surgery screw,
Comprising: shell fixed by screw fixation spring tab and screw.This fixing device is suitable to spiral shell
Silk nail is fixed therein portion so that screw is integral with external fixation device shape, plays storage
Deposit and protect the effect of screw, it is possible to separate with screw after work.
The screw fixation spring tab of described device has 4-8 piece, it is preferable that fixation spring tab is length
Spend equal, be spaced identical being uniformly distributed, fixation spring tab trend for from screw shell diagonal to
Under, the head end of shell fragment surrounds a circular hole, the diameter of this circular hole and internal screw shaft diameter one
Cause or smaller.Described shell fragment has certain resilient properties, can have certain displacement laterally, i.e.
Moved by from outside adaptability during the pressure effect of the head of a nail during screw moves down
Dynamic, under work or quiescent condition, no matter all can keep the vertical center position of screw.
Casing appearance fixed by the screw of described device is a square or cuboid sample, and it is fitted
In screw is fixed therein portion, plays and store and the effect of protection screw.
The screw of described device fix the internal diameter of shell identical with screw head of a nail end diameter or
Slightly larger than screw head of a nail end diameter, it can play the effect of fixing internal screw, prevent spiral shell
Silk nail swings at device inner transition.
Described device fixes shell rear portion at screw, i.e. screw head of a nail end rear has inwardly
The microprotrusion in portion, it is preferable that a diameter of 0-1.0mm of this projection, protrudes inwardly from scope
0-1.0mm, plays the effect preventing screw from coming off backward.
The screw of described device is fixed shell and is had certain resilient properties, can be to mould
Material material, this shell can not only setscrew, moreover it is possible to conveniently installed by screw
Therein.
In a non-operative state, screw is stored in fixing device partial interior to described device,
When needed screw can also be installed into fixing device from fixture enclosure part tail end
In.
Under described device busy state, under the auxiliary of fixation spring tab and shell, screw
Nail can remain the direction being perpendicular to surface of bone, by stubborn spike devices such as screwdriver, and can be by
Screw in described fixing device progressively pierces inside bone, and may finally take off with fixing device
From.
The screw head of a nail in described device is in the rotating down pressing effect by twisting spike devices
Under, progressively it is drilled down in bone, during piercing, screw fixation spring tab is bound along with twisting
That puts produces corresponding mobile to bottom offset to surrounding, same ensureing that screw moves gradually downward
Time keep screw direction be in vertical center position all the time, when screw pierces in bone completely
After, shell fragment is bound to original position again, and whole screw fixing device separates with screw.
Further object is that a kind of combination unit of offer, it includes according to this
The fixing device of the surgery screw described in invention and screw.
The present invention further an object is that offer fixing device of the present invention or combination
Device application in manufacturing the fixed system of bone connection sheet or repair materials.
By using assembly of the invention, the installation of surgery screw, store, sterilize,
Apply more convenient, alleviate operative doctor and nurse job amount, moreover it is possible to avoid to the full extent
Screw in operation process comes off and misses air draught danger, is greatly enhanced procedure efficiency.
In this application, without particularly illustrating, then the position relationship of each assembly
Based on position relationship shown in the drawings, the device used, instrument, assembly, size and
His condition etc. is all well-known in the art, or those skilled in the art are according to application
Describe and combine what prior art can realize.
About the description of term in the present invention, if with this area before description difference,
Should be as the criterion with the description in the application.
