Description
Technical field
The utility model relates to Orthopedic Clinical bone plate field more particularly to a kind of destressing metal locking type osteopathy plate systems
System.
Background technique
Bone plate is plate bone fracture internal fixing device part with holes, is clinically often used cooperatively with bone screws or synthetism silk.At present
Bone plate used in clinic can be made into bar shaped, Y shape, L shape, T shape etc. according to the different purposes of bone plate.In clinic, it is being implanted into
Greateset risk after human body is exactly the failure of desired use.Bone plate is as a kind of important medical instrument, after being implanted into human body, leads to
Bone plate and skeleton are locked frequently with bone screws.And squeeze into the bone screws in skeleton, then to bear skeleton
Interior stress, under long-term high stress environment, bone screws are likely to occur crack and are even broken, and cause implantation material to be broken, synthetism
Plate system cannot effectively fix fracture portions bone, influence to treat.
Utility model content
Technical problem to be solved by the utility model is: the deficiency in order to overcome the prior art, the utility model provides one
Kind can effectively disperse to bear skeleton internal stress, avoid being broken, and promote a kind of destressing metal of patient's early recovery
Locking bone fracture plate system.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of destressing metal locking type osteopathy plate system
System, including lockplate and is plugged on lockplate the bone screws by lockplate and skeletal fixation, is provided at least two on lockplate
Lock screw set, the bone screws grafting and with lock screw cover locking；The bone screws include that sleeve and cooperation are plugged on
Core bar in sleeve；The sleeve inner is hollow to be inserted into for core bar, integrally formed with circumferential with externally threaded at the top of sleeve
Lower nut；The core bar is that bottom stretches out sleeve bottom surface and top and is higher than lower nut top surface, at the top of the core bar integrally formed with
It is circumferential that there is externally threaded upper cap nut；In the external screw thread inner wall of nut and upper cap nut is respectively provided under the lock screw set is corresponding
Screw thread.
Further, closely and stress, core bar bottom end and bone-contact are effectively conducted with skeletal fixation for the ease of core bar
Face is arc arcuate surface.
Further, for the ease of sleeve and bone-contact and it is effectively conducted stress, sleeve peripheral outer wall and sleeve bottom surface
Between for chamfering connect.
When operation, at the bone for needing locking bone fracture plate, lockplate is placed, lock screw set is then directed at and squeezes into sleeve
And nut lower at the top of sleeve and lock screw are covered into internal thread locking.Alignment sleeve squeezes into core bar in sleeve and will be at the top of core bar
Upper cap nut and lock screw cover internal thread locking, and the operation of locking bone fracture plate can be completed.Match between sleeve and core bar for gap
It closes.
The utility model has the beneficial effects that a kind of destressing metal locking type osteopathy plate system provided by the utility model,
After bone screws are implanted into human body, core bar and sleeve can bear skeleton stress simultaneously, and core bar is plugged in sleeve, skeleton
The stress of generation partial offset, reduction skeleton stress can cause the wind of bone screws fracture in core bar and sleeve clearance fit
Danger enables lockplate and bone screws to play expected effect, promotes patient's early recovery.

Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
A kind of destressing metal locking type osteopathy plate system as shown in Figures 1 to 4, is the utility model optimum embodiment,
Including lockplate 1 and it is plugged on the bone screws of lockplate 1 and skeletal fixation on lockplate 1.At least two are provided on lockplate 1
Lock screw set 2, the bone screws grafting are simultaneously locked with lock screw set 2.
Bone screws include sleeve 3 and the core bar 4 that cooperation is plugged in sleeve 3.For the ease of sleeve 3 and bone-contact and have
Effect conducts stress, connects between 3 bottom surface of 3 peripheral outer wall of sleeve and sleeve for chamfering.3 inner hollow of sleeve is inserted into for core bar 4, set
3 top of cylinder has externally threaded lower nut 5 integrally formed with circumferential.
Closely and it is effectively conducted stress with skeletal fixation for the ease of core bar 4,4 bottom end of core bar and bone-contact face are arc
Arcuate surface.Core bar 4 is that bottom stretches out 3 bottom surface of sleeve and top and is higher than lower 5 top surface of nut, 4 top of core bar integrally formed with
It is circumferential that there is externally threaded upper cap nut 6.
The external screw thread inner wall of the corresponding lower nut 5 of lock screw set 2 and upper cap nut 6 is respectively provided with internal screw thread 7.
When operation, at the bone for needing locking bone fracture plate, lockplate 1 is placed, lock screw set 2 is then directed at and squeezes into set
Cylinder 3 simultaneously locks nut 5 lower at the top of sleeve 3 and lock screw 2 internal screw threads 7 of set.Alignment sleeve 3 squeezes into core bar 4 simultaneously in sleeve 3
4 top upper cap nut 6 of core bar is covered 2 internal screw threads 7 with lock screw to lock, the operation of locking bone fracture plate can be completed.Sleeve 3 and core
It is clearance fit between bar 4.
After lockplate 1 and bone screws implantation human body, bone screws can bear the stress in skeleton.Due to 4 bottom of core bar
Stretching out 3 bottom surface of sleeve and bone-contact, core bar 4 can meet with stresses, and 3 outer wall of sleeve has been also subjected to stress, and core bar 4 and sleeve 3
Between be clearance fit, core bar 4 bear stress and sleeve 3 bear part stress can thus clearance fit offset part, subtract
Lack stress to the entire effect of bone screws, reduces the risk that bone screws are broken.
A kind of destressing metal locking type osteopathy plate system being designed in this way, after bone screws are implanted into human body, core bar 4 and sleeve 3
Skeleton stress can be born simultaneously and offsets part stress, reduced the risk that skeleton stress causes bone screws to be broken, made
Lockplate 1 and bone screws can play expected effect, promote patient's early recovery.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
