Description
Technical field
The utility model relates to a kind of fixed consumptive materials of medical treatment of merging human body, especially for human spine malformation correction
It is placed in extender in the backbone pitman body in human spine.
Background technique
Periodically constantly extend in the correction of children's Early onset deformity of spine, needing an instrument and being done to children's backbone,
With spinal growth, gradually correction deformity, is finally reached ideal orthopedic as a result, doing the spinal fusion surgery of terminal phase again.Mesh
The spinal growth stick of preceding application is primarily present following problems:
(1) application for growing valve, it is larger when repeatedly extending backbone to need to cut range, needs general anesthesia to operate, repeatedly hand
Art influences greatly children, costly.(2) some slidings extend device and need to reserve longer pitman to small in correction area two sides
Youngster's activity and life make a big impact.(3) magnetic force extension installation cost is high, prolongation effect is limited, is difficult to promote at home.
Summary of the invention
In view of existing spinal growth stick there are drawbacks described above, the purpose of this utility model is to provide it is a kind of it is easily operated,
Safely, effectively, extender in backbone pitman body inexpensively, to solve the problems, such as that children's backbone extends very well.
To achieve the goals above, the technical solution that the utility model is taken is as follows: a kind of backbone pitman body is interior to be extended
Device, including pitman；It is characterized by also including extender cuboids；Intermediate be equipped with extends operation above extender cuboid
Hole, the two sides for extending handle hole are set there are four pitman fixation hole, and extender cuboid sets that there are two what is be parallel to each other left and right to pass through
Logical pitman receiving opening extends handle hole side and is connected with pitman receiving opening, pitman fixation hole lower end and company
Receiving opening of taking over the baton is connected；Pitman be two, pitman one end be equipped with rack gear, rack gear be mounted on pitman receiving opening and
Two pitman rack gears are equipped with fastening screw, fastening screw and pitman apical grafting towards handle hole, pitman fixation hole is extended.
The utility model further includes the T shape gimlet operated with；The working end of T shape gimlet is equipped with tooth post, tooth post
Tooth form matches with the tooth form of pitman rack gear.T shape gimlet is rotated, pitman can be extended or be shortened to two sides.
Extender prevents from occurring in use process by being made with the good titanium alloy of histocompatbility in backbone pitman body
Rejection.
The utility model structure is simple, easily operated, safe and effective；It is cheap compared with magnetic force extends device.It uses
When, it is implanted into pedicle nail in the concave side of human spine lateral bending first, measures the length of required pitman in vivo, and after estimation
It is continuous to need extended length, the pitman for being suitble to length is chosen, two pitmans are penetrated into pitman receiving opening, and in opposite
It is pierced by；The fastening screw of pitman fixation hole is tightened, the firm fixation of pitman is effectively prevent moving by fastening screw.
When later period needs to do pitman extension, it can be cut under local anaesthesia in extender surface, appear extender surface
Fastening screw is unclamped in five holes, and gimlet working end is inserted into and extends handle hole, and the rack gear of tooth post and pitman coincide,
It is solid then to tighten fastening screw so that pitman extends to ideal length to two sides for rotary screw cone, tooth post band carry-over bar
Determine pitman, keep extending length to fix, finally sew up a wound, completes operation.
The utility model is designed on inventor's many years clinical experience basis, is overcome original backbone and is extended device
The shortcomings that, the utility model can repeatedly extend backbone in small notch under local anaesthesia.Compared with prior art, notch contracts significantly
It is small, by being reduced to 2.5cm more than original 10cm, postoperative complication and expense are substantially reduced, avoids general anesthesia repeatedly to children
Nerve cause to damage.
Extender in backbone pitman body, while being suitable for 6.0mm system and 5.5mm system pitman.

Specific embodiment
Below according to attached drawing and implement to be described in further details the utility model.As shown in Fig. 1 and Fig. 2: a kind of ridge
Extender in column pitman body, including pitman 5；It further include extender cuboid 1；Extender cuboid 1 is intermediate above to be equipped with
Extend handle hole 2, extends handle hole 2 for extending pitman；The two sides for extending handle hole 2 are set there are four pitman fixation hole 3,
Extender cuboid 1 is set there are two the pitman receiving opening 4 for the left and right perforation being parallel to each other, and extends 2 side of handle hole and company
Receiving opening 4 of taking over the baton is connected, and 3 lower end of pitman fixation hole is connected with pitman receiving opening 4；Referring to Fig. 3: pitman 5
It is two, 5 one end of pitman is equipped with rack gear 501, and rack gear 501 is mounted on the rack gear of pitman receiving opening 4 and two pitmans
501 towards handle hole 2 is extended, i.e. the dentate part of rack gear is face-to-face, corresponds to each other, and pitman fixation hole 3 is equipped with fastening spiral shell
Silk, fastening screw and 5 apical grafting of pitman, pitman is fixed.
Referring to fig. 4: the utility model matching used T shape gimlet 6 when further including operation；The working end of T shape gimlet 6
Equipped with tooth post 601, the tooth form of tooth post 601 matches with the tooth form of pitman rack gear 501, mating correspondence.Extend the hole of handle hole 3
Shape specification is adapted with the side surface shape specification of tooth post 601.
Pitman 5 is cylindrical body, and one end of cylindrical body pitman 5 is equipped with rack gear 501, the other end is used for and merging backbone vertebra
The pedicle nail of body connects.
Extender cuboid 1 and pitman 5 effectively prevent use process by being made with the good titanium alloy of histocompatbility
In there is rejection.
In use, being implanted into pedicle nail in the concave side of human spine lateral bending first, required pitman is measured in vivo
Length, and estimate the subsequent extended length of needs, the pitman for being suitble to length is chosen, two connection stick section of rack are penetrated
Pitman receiving opening, and be pierced by opposite, keep the dentate part of rack gear face-to-face, corresponds to each other；Tighten pitman fixation hole
Fastening screw, fastening screw fixes pitman is firm.
When later period needs to do pitman extension, it can be cut under local anaesthesia in extender surface, appear extender surface
Five holes manifest and extend four pitman fixation holes that handle hole and its two sides are equipped with；Fastening screw is unclamped, by T
The working end insertion of shape gimlet extends handle hole, and tooth post and pitman rack gear are coincide, and rotates T shape gimlet, and tooth post drives
The rack gear of pitman then tightens fastening screw and is fixedly connected with stick so that pitman extends to ideal length to two sides, keeps prolonging
Length；It sews up a wound.Aforesaid operations use local anaesthesia, complete under infant waking state, avoid general anesthesia repeatedly to small
The nerve of youngster causes to damage, and guarantees infant safety.
