Description
Technical field
The present invention relates to a kind of medicine equipment, more specifically a kind of extension intramedullary needle for reducing pin hole.
Background technology
Nowadays, people increasingly pay attention to for own health and external image, are intended to oneself have a healthy body
With a preferable stature.With the development of Limb lengthening technology, more and more people for wanting to increase can pass through bone lengthening
Realize the dream of oneself.
Limbs are by structure compositions such as bone, muscle, nerve, blood vessel, skins, increase limbs length, it is necessary to make this
The length of a little structures all increases.The effect of wherein bone is most important, extends also relatively difficult.Conventional method is to pass through operation
Bone is cut off, multigroup draw point or steel nail pass through the perforation of intramedullary needle, and outside lead body, are connected to external fixed mount.In art
Afterwards daily, adjusts the bolt of fixed mount in vitro, pulls knochenbruch both ends in the opposite direction, makes to produce between knochenbruch empty
Gap.The bone that the processes such as plastotype are converted into maturation is transformed by the organization of hematoma of the broken ends of fractured bone, intramembranous ossification and enchondral ossification, poroma,
After a period of time, bone is just extended.The soft tissues such as muscle, nerve, blood vessel, skin are also extended therewith.It is but conventional
Method need to set multiple draw points on human body, it may appear that the problem of pin hole scar is more, knochenbruch gap is adjusted by fixed mount,
In the presence of adjust it is inconvenient the problem of.
The content of the invention
It is existing so as to solve the invention provides a kind of extension intramedullary needle for reducing pin hole based on above technical problem
In technology, it is inconvenient to be adjusted caused by using fixer in vitro, the technical problem more than pin hole scar.
The technical solution adopted by the present invention is as follows：
A kind of extension intramedullary needle for reducing pin hole, including intramedullary needle main body, fixing glue and regulating nail；The fixing glue passes through
Intramedullary needle main body upper end；The intramedullary needle lower body part is provided through the regulating tank of intramedullary needle main body；The regulating tank is vertical
Side be provided with rack；The regulating nail passes through regulating tank；The gear being meshed with rack is provided with the middle part of the regulating nail,
Wheel and rack is engaged, and regulating nail is connected with intramedullary needle main body.
Specifically, the regulating tank both sides of the edge are provided with the bumping post for limiting gear translation.
Specifically, the regulating nail both ends are additionally provided with regulation handle；Regulating nail both ends end face is polygonal grooves；
The connection main body of the regulation handle is corresponding with regulating nail both ends polygonal grooves convex stupefied；The connection of the regulation handle
The corresponding groove in main body insertion regulating nail both ends, regulation handle is connected with regulating nail.
Specifically, to be provided with card stupefied for the gear both ends on the regulating nail；The card is stupefied to form neck between gear；
Two sleeves are cased with the regulating nail；Described sleeve one end is provided with baffle plate；The baffle plate is caught in neck, for preventing to cover
Cylinder moves in the horizontal direction.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, the present invention extends knochenbruch gap length by intramedullary needle internal regulation groove, makes regulation more convenient.
2nd, without fixer in vitro, the needle track caused by avoiding long-term use of fixator infects the present invention.
3rd, when fixing human and intramedullary needle of the present invention, it is only necessary to the fixing glue on top and the regulating nail of bottom, required pin
Hole is few, and postoperative stayed pin hole scar is few, and the fixing glue on top need not be stretched into the human body, can further reduce pin hole scar
Trace, reduce pin site infection.
4th, the present invention, which blocks, to be moved left and right with limiting gear, avoid gear from entering in bone, bone is caused damage.
5th, regulation handle of the present invention not only can conveniently adjust the gap between knochenbruch, and regulation handle is lived with regulating nail
Dynamic connection, regulation handle when that need not adjust, can be pulled down, avoid patient's maloperation.
6th, the sleeve that the present invention is set with flesh contact, can avoid regulating nail from directly being contacted with the human body when in use,
When rotating regulating nail, the human body is caused damage, baffle plate can avoid sleeve from being dropped from regulating nail.
