Description
Technical field
The present invention relates to a kind of medical treatment for inserting human body fixed consumptive material, particularly inserting for human spine malformation correction
Extender in backbone pitman body in human spine.
Background technology
For in the correction of children's Early onset deformity of spine, it is desirable to have an apparatus does periodically constantly extension to children's backbone,
With spinal growth, gradually correction deformity, finally reaches preferable orthopedic result, then do the spinal fusion surgery in whole latter stage.Mesh
The spinal growth rod of preceding application is primarily present following problems:
(1)The application of valve is grown, needs incision scope larger in repeatedly extension backbone, it is necessary to general anesthesia operation, repeatedly operation pair
Children's influence is big, costly.(2)Some, which slide extension fixture, needs to live to children in the reserved longer pitman in correction area both sides
Dynamic and life makes a big impact.(3)Magnetic force extension fixture is costly, prolongation effect is limited, is difficult to promote at home.
The content of the invention
In view of there is drawbacks described above in existing spinal growth rod, it is an object of the invention to provide one kind it is easily operated, safe,
Effectively, extender in cheap backbone pitman body, to solve the problem of children's backbone extends very well.
To achieve these goals, the technical scheme that the present invention takes is as follows:Extender in a kind of backbone pitman body, bag
Include pitman;It is characterized in that:Also include extender cuboid;Provided with extension handle hole in the middle of above extender cuboid, prolong
The both sides of long handle hole are provided with four pitman fixing holes, and extender cuboid is provided with two left and right insertions being parallel to each other
Pitman receiving opening, extension handle hole side is connected with pitman receiving opening, pitman fixing hole lower end and pitman
Receiving opening is connected;Pitman is two, and pitman one end is provided with rack, and rack is arranged on pitman receiving opening and two
Pitman rack is towards extension handle hole, and pitman fixing hole is provided with fastening screw, fastening screw and pitman apical grafting.
Present invention additionally comprises the T-shaped gimlet operated with;The working end of T-shaped gimlet is provided with tooth post, the tooth form of tooth post
Matched with the tooth form of pitman rack.T-shaped gimlet is rotated, pitman can be extended to both sides or shortening.
Extender is made up of the titanium alloy good with histocompatbility in backbone pitman body, prevents appearance during use
Rejection.
The present invention is simple in construction, easily operated, safe and effective;It is cheap compared with magnetic force extension fixture.In use,
Pedicle nail is implanted into the concave side of human spine lateral bending first, the length of pitman needed for measuring in vivo, and estimate follow-up
The length of extension is needed, the pitman for being adapted to length is chosen, two pitmans is penetrated into pitman receiving opening, and wear in opposite
Go out;The fastening screw of pitman fixing hole is tightened, the firm fixation of pitman is effectively prevented movement by fastening screw.
When later stage needs to do pitman extension, extender surface can be appeared under local anaesthesia in the incision of extender surface
Five holes, unclamp fastening screw, by gimlet working end insertion extension handle hole, and the rack of tooth post and pitman coincide,
Rotary screw is bored, tooth post band carry-over bar, and then causes pitman to extend to ideal length to both sides, is then tightened fastening screw and is consolidated
Determine pitman, keep extending length to fix, finally sew up a wound, complete operation.
The present invention is invented on inventor for many years clinical experience basis, overcomes lacking for original backbone extension fixture
Point, the present invention can under local anaesthesia small otch to the multiple extension of backbone.Compared with prior art, otch is substantially reduced, by original
It is reduced to 2.5cm more than the 10cm come, substantially reduces postoperative complication and expense, it is to avoid general anesthesia repeatedly is made to the nerve of children
Into damage.
Extender in backbone pitman body, while suitable for 6.0mm systems and 5.5mm system pitmans.

Embodiment
The present invention is described in further details below according to accompanying drawing and implementation.As shown in Fig. 1 and Fig. 2:A kind of backbone connects
Take over the baton internal extender, including pitman 5;Also include extender cuboid 1;Extender cuboid 1 is provided with extension in the middle of above
Handle hole 2, extension handle hole 2 is used to extend pitman;Extend the both sides of handle hole 2 provided with four pitman fixing holes 3, extension
Pitman receiving opening 4 of the device cuboid 1 provided with two left and right insertions being parallel to each other, the side of extension handle hole 2 and pitman
Receiving opening 4 is connected, and the lower end of pitman fixing hole 3 is connected with pitman receiving opening 4;Referring to Fig. 3:Pitman 5 is two
Root, one end of pitman 5 is provided with rack 501, and rack 501 is arranged on the court of rack 501 of pitman receiving opening 4 and two pitmans
Tooth-like part of anything to extension handle hole 2, i.e. rack is face-to-face, mutually correspondence, and pitman fixing hole 3 is provided with fastening screw, tightly
Gu screw and the apical grafting of pitman 5, pitman is fixed.
Referring to Fig. 4:Present invention additionally comprises matching used T-shaped gimlet 6 during operation;The working end of T-shaped gimlet 6 is provided with
Tooth post 601, the tooth form of tooth post 601 matches with the tooth form of pitman rack 501, supporting correspondence.Extend the hole shape rule of handle hole 3
Lattice are adapted with the side surface shape specification of tooth post 601.
Pitman 5 is cylinder, and one end of cylinder pitman 5 is used for inserting backbone vertebra provided with rack 501, the other end
The pedicle nail connection of body.
Extender cuboid 1 and pitman 5 are made up of the titanium alloy good with histocompatbility, effectively prevent from using process
In there is rejection.
In use, pedicle nail is implanted into the concave side of human spine lateral bending first, pitman needed for measuring in vivo
Length, and estimate the follow-up length for needing to extend, the pitman for being adapted to length is chosen, two connection stick section of rack are penetrated
Pitman receiving opening, and passed in opposite, make the tooth-like part of anything of rack face-to-face, mutually correspondence;Tighten pitman fixing hole
