Abstract
The present invention relates to the field of medical instrument technology, and disclose a kind of osteoporosis pedicle screw, including screw, the screw suit is in nail seat, surface of the screw far from nail seat one end offers through-hole, internal activity of the nail seat far from screw one end is connected with nail plug, one section of cavity being in communication with the outside is offered inside screw, nail seat surface position corresponding with through-hole offers outlet, outside of the nail seat far from through-hole one end open up it is fluted, top of the nail seat far from groove one end be taper.The osteoporosis pedicle screw, by the way that through-hole is arranged and takes hollow screw, so that this pedicle screw is after entering subjects bones inside, operator can add bone cement by through-hole to the bones of patient, to reach preferable fixed effect using bone cement, the sclerotin intensity of sufferers of osteoporosis face is substantially increased, the structure of taper may help to user and preferably squeeze into pedicle screw inside subjects bones.
Description
Technical field
The present invention relates to the field of medical instrument technology, specially a kind of osteoporosis pedicle screw.
Background technology
Pedicle screw is mainly to squeeze into the bones of people human skeleton is helped to reply, and plays correcting, can be with
For correcting Juvenile development deformity etc..
There are osteoporosis, osteoporosis, that is, osteoporosis, caused by being many reasons with what skeleton deformity generated
One group of osteopathy, it is in normal rates with matrix that bone tissue, which has normal calcification, calcium salt, and spy is reduced to unit volume inner bone tissues amount
The metabolic bone disease of point becomes.In most osteoporosises, caused by the reduction of bone tissue increases mainly due to bone absorption.With bone
Pain is characterized with fracture is easy to, and the bone of sufferers of osteoporosis face is more fragile compared with normal bone, therefore at some
Although having stamped pedicle screw for sufferers of osteoporosis face, but because sclerotin reason can not be fixed preferably, without sclerotin
The loose dedicated pedicle screw of patient brings bigger difficulty to the operation of sufferers of osteoporosis face.
Invention content
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of osteoporosis pedicle screw, has suitable sclerotin
The advantages that loose patient's constitution, solves the problems, such as that sufferers of osteoporosis face is bad using common pedicle screw effect.
(2) technical solution
To realize that above-mentioned osteoporosis is suitble to sufferers of osteoporosis face constitution purpose, the present invention to provide as follows with pedicle screw
Technical solution：A kind of osteoporosis pedicle screw, including screw, for the screw suit in nail seat, the screw is separate
The surface of nail seat one end offers through-hole, and internal activity of the nail seat far from screw one end is connected with nail plug.
Preferably, the cavity that one end is in communication with the outside is offered inside the screw.
Preferably, nail seat surface position corresponding with through-hole offers outlet.
Preferably, outside of the nail seat far from through-hole one end opens up fluted.
Preferably, top of the nail seat far from groove one end is taper.
(3) advantageous effect
Compared with prior art, the present invention provides a kind of osteoporosis pedicle screw, have following advantageous effect,
The osteoporosis pedicle screw, by the way that through-hole is arranged and takes hollow screw so that this pedicle screw is entering
After subjects bones inside, operator can add bone cement by through-hole to the bones of patient, to utilize bone cement
Reach preferable fixed effect, substantially increases the sclerotin intensity of sufferers of osteoporosis face.
Description of the drawings
Fig. 1 is structure of the invention diagrammatic cross-section；
Fig. 2 is structure of the invention outside schematic diagram.
In figure：1 screw, 2 nail seats, 3 through-holes, 4 nail plugs, 5 grooves.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, a kind of osteoporosis pedicle screw, including screw 1, screw 1 are sleeved in nail seat 2, spiral shell
1 surface far from 2 one end of nail seat of nail offers through-hole 3, and internal activity of the nail seat 2 far from 1 one end of screw is connected with nail plug 4.
One section of cavity being in communication with the outside is offered inside screw 1.
2 surface of nail seat position corresponding with through-hole 3 offers outlet.
Outside of the nail seat 2 far from 3 one end of through-hole opens up fluted 5.
Top of the nail seat 2 far from 5 one end of groove is taper.
Pedicle screw is that when treating skeletal diseases and correction deformity, commonly a kind of instrument, human body are like one to people
The composition of a armored concrete is the same, and bone is exactly reinforcing bar, and flesh and blood is exactly concrete, and armored concrete is being repaired in life
Additional reinforcing bar is generally taken to be reinforced when composition, in the reparation of skeleton, pedicle screw is exactly people for repairing
The additional reinforcing bar of bone can help doctor to carry out Minimally Invasive Surgery etc., but it is setting that present pedicle screw, which uses all,
On the basis of normal bone, to encounter special circumstances just seem that some are unable to do what one wishes, for example, sufferers of osteoporosis face sclerotin compared with
The density of ordinary person is relatively low, and corresponding fixed force is not achieved in very possible bone after pedicle screw is thrown into so that vertebral arch
Root toner screw carries out work and increases difficulty, and can also increase pain to patient again after falling off, and increases flower
Take, we are that the outer binder of addition improves the intensity for needing to repair position faced with this situation in life, consequently facilitating applying
Work, it is exactly bone cement just to have bone cement, bone cement during present orthopaedics therapy, the entitled acrylic cement of chemistry or
Polymethyl methacrylate, nineteen fifty-one, Sweden Klaer use PMMA to fix material as hip prosthesis；Charnley in 1958
It furthers investigate and promotes the use of, to make the displacement of bone cement fixed fae body succeed；It succeeds in developing and answers within 1978 in China
With with clinic, bone cement is being many times substitute as joint, and the people for helping some joints that can not move replaces
One new joint, in the present invention by opening up special bone cement through-hole 3 on traditional pedicle screw surface, in this hair
The bright inner cavity that bone cement is just poured into screw 1 from the axle center of nail seat 2 later into subjects bones, it is solid using the property of bone cement
The bone of the fixed present invention and patient, and as a kind of thing similar to gel, by the bone that sufferers of osteoporosis face is originally loose
Matter is reinforced so that the sclerotin of sufferers of osteoporosis face meets the requirement using pedicle screw, and the configuration of the present invention is simple mitigates
The pain of patient, while being also that doctor creates preferable operation and Curing circumstance, there is stronger practicability, the present invention couple
In pedicle screw how using there is no improvement, therefore which is not described herein again, while having opened up groove 5 in the outside of nail seat 2
It is easy to use the present invention.
In conclusion the osteoporosis pedicle screw, by the way that through-hole 3 is arranged and takes hollow screw 1 so that
For this pedicle screw after entering subjects bones inside, operator can add bone by through-hole 3 to the bones of patient
Cement substantially increases the sclerotin intensity of sufferers of osteoporosis face to reach preferable fixed effect using bone cement.
It should be noted that herein, relational terms such as first and second and the like are used merely to a reality
