Description
Technical field
This utility model is related to technical field of medical instruments, solid more particularly, to a kind of tibial insertion of anterior cruciate ligament stop fracture
Determine device.
Background technology
Knee joint function disorder is most commonly seen bone injury in daily life, especially with sending out for communication and building industry
Exhibition, in increase trend.Therefore, how simpler, more firmly fixing limbs are fractured, and how to reduce to fracture blood supply as far as possible
Affect so as to the emphasis and difficult point that promote union of fracture to be always orthopedist's concern.When bone ruptures, need to fix knochenbruch
Together, in order to correct healing, otherwise, it is easy to which the faulty unions such as dislocation occur.Traditional method is by skeleton
After para-position, by way of suture, bones are fixed together, but are because that suture is thinner, rely solely on suture difficult
With by skeletal fixation together, in order to preferably heal, need it is a kind of it is simple easily using holder skeleton para-position to be fixed,
Avoid secondary insult.
The content of the invention
In order to overcome the shortcomings of in background technology, the utility model discloses a kind of tibial insertion of anterior cruciate ligament stop fracture is solid
Determine device, it is adaptable to which the fracture of the tibial insertion of anterior cruciate ligament stop under arthroscope recovers operation.
In order to realize the goal of the invention, this utility model is adopted the following technical scheme that：A kind of tibial insertion of anterior cruciate ligament stops
Point fracture fixing apparatuss, including upper holder, fixing line, threading needle and external fixator；Fixed device is elongated ellipse
Body structure, is provided with the needle tray of a placement threading needle needle point on the one end side of ellipsoidal structure, needle tray tiltedly stretches to fixation
The center of device；The side surface of fixed device is additionally provided with fixed line three-way hole；Threading is additionally provided with the threading needle
Hole；The fixing line sequentially passes through fixed line three-way hole and through wires hole, and two ends of fixing line are fixed by external fixator；
The fixed line three-way hole includes two passes hole, and the fixing line sequentially passes through two access openings.
For further improved technology scheme, the inner bottom of needle tray described in the utility model is provided with Magnet layer, described
The tip position of threading needle is the metallic iron or Magnet attracted with Magnet layer magnetic picture.
For further improved technology scheme, the inside of needle tray described in the utility model is additionally provided with fixed threading needle needle point
Rubber fixed area.
For further improved technology scheme, through wires hole described in the utility model is arranged on the needle tip of threading needle；It is described
The other end of through wires hole is connected with needle handle.
For further improved technology scheme, on this utility model, holder is polyether-ether-ketone material.
As a result of above-mentioned technical proposal, this utility model has the advantages that：Hand over before described in the utility model
Upper holder can be adjusted fixing line suitable after fixing line fixation, then by fork ligament tibia stop fracture fixing apparatuss
Elasticity and position, then outer lines holder is fixed on the other end of fracture region, is conducive to the rehabilitation of skeleton.
When upper holder is withstood on fracture region by threading needle, the ductile deformation of metal itself is on the one hand make use of, be increased
Pressure between upper holder and threading needle will not be separated ensureing both, led to first in another aspect on holder inside needle tray
Rubber extruded deformation in rubber fixed area is crossed, and the magnetic force of needle point and Magnet layer attracts, it is ensured that both will not separate together；When
Threading needle ejects upper holder behind fracture region, using the ductile deformation of metal itself, you can the angle of holder in change,
As upper holder is slender structure, the position of fixed line three-way hole is caused when line is strained and fixed, and upper holder can transverse gear
Enter stuck state in commitment positions, upper holder is automatically stuck outside fracture region.
This utility model is applicable not only to the fixation after tibia sites are fractured and rehabilitation, applies also for other any positions
Fixed and rehabilitation, this utility model simple structure are novel in design, can be widely used in the middle of medical treatment.

Specific embodiment
Explanation this utility model that can be detailed by the following examples, open the purpose of this utility model are intended to protection
All technological improvements in the range of this utility model.
A kind of tibial insertion of anterior cruciate ligament stop fracture fixing apparatuss, including upper holder 1, fixing line 3, threading needle 4 and outside
Holder 6；Fixed device 1 is elongated ellipsoidal configuration, and a placement is provided with the one end side of ellipsoidal structure
The needle tray 2 of 4 needle point of threading needle, needle tray 2 tiltedly stretch to the center of holder 1；The centre position of fixed device 1 also sets
It is equipped with fixed line three-way hole 101；The fixed line three-way hole 101 includes two passes hole, and the fixing line 3 sequentially passes through two passages
Hole.Through wires hole 401 is additionally provided with the threading needle 4；The fixing line 3 sequentially passes through fixed line three-way hole 101 and through wires hole
401, and two ends of fixing line 3 are fixed by external fixator 6.The inner bottom of the needle tray 2 is provided with Magnet layer
201, the tip position of the threading needle 4 is the metallic iron or Magnet attracted with 201 magnetic picture of Magnet layer.The needle tray 2 it is interior
