Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to one kind is cooperated by pedicle nail and pouch to limit
The effect of higher intensity and support construction is connected up in bone cement flowing processed and bone endoplasm bone and cortex bone.
Background technique
For osteoporosis and with the repressive patient for losing wound, needs to fill bone cement into bone and use pedicle nail
It is fixed.The scheme of tradition perfusion bone cement is first to be pierced into bone with passage-opening awl, and then silica gel balloon urinary is brought into and inflated, with
Just the space of injection bone cement is cleaned out in bone, and sacculus taking-up is reinjected into bone cement thereafter.The program is lacked there are following
Point: first, the silica gel balloon urinary endurance of inflation is poor, is easily deformed when clearing up space and is unable to reach ideal cleaning effect；The
Two, the silica gel balloon urinary of inflation is had pierced risk, needs to re-replace sacculus at this time, causes to delay operating time, and ball
Capsule is expensive；Third cleans out the sacculus in space in recycling, can not directly take out, need to take out together passage-opening awl sometimes
Passage-opening awl is worn back again later, leads to that operating time lengthens and the passage-opening awl worn back again is possible to positioning and is not allowed；4th, it should
In scheme, because first to withdraw sacculus Reperfu- sion bone cement, so bone cement limits after entering bone without foreign object, bone cement exists
A possibility that flowing, and bone cement once encounters nerve will result in serious consequence；5th, the bone cement and vertebral arch of traditional scheme
Root nail between only contact fix, in later period rehabilitation course, as patient does some strenuous exercises, it is possible to cause bone cement with
It is broken between pedicle nail.After more thorny problem may lock pedicle nail because bone density is bad, causes to loosen and fall off, nothing
Method reaches the effect of expection.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of structures simply, design is more reasonable, surgical procedure is more square
Just, accurate positioning, the pedicle nail structure with pouch that can prevent bone cement from flowing.
In order to solve the above technical problems, the utility model adopts the following technical solution: a kind of pedicle nail knot with pouch
Structure, it is characterised in that: include pedicle nail and pouch, forms pedicle nail pouch, and before pouch is fixed on pedicle nail
End；The front end that the pouch is first fixed on a pouch connector is then passed through inside pedicle nail；It further include having tube channel, and tube channel
Front end connected with pouch connector；Pouch connector is passed through inside pedicle nail in conjunction with pedicle nail by tube channel, and pouch
Then stretch out in the front end of pedicle nail.
The pouch connector is a pouch nipple, and pouch nipple is connected using thread.
The front end of tube channel is connected through thread with pouch nipple.
Pouch nipple with thread is passed through inside pedicle nail by tube channel and penetrates inside and outside tooth and pedicle nail
In conjunction with.
Using the hollow design that can be connected bone cement entrance inside tube channel and tube channel, pouch inside pouch nipple
There is side opening in nipple side.When operation, bone cement is mainly the center side opening injection pouch for passing through pouch nipple, but same
When can also be poured by side opening, and those side openings can also play the role of disperse pressure.
Pouch nipple is equipped with a snap ring in front, and pouch nipple is locked by the snap ring and pedicle nail, card
Ring is open type structure.
Pouch is made of mesh material, fixes after being fixed on the front end of pouch nipple through lantern ring.Reach
Effect that is ventilative but being not easy percolating water can effectively limit the flowing (setting time of bone cement is 6 minutes or so) of bone cement,
And the liquid of the flowing in bone cement will be slow evaporation and touch nerve without flowing out.
Pouch is fixed on the front end of pouch nipple through lantern ring, and lantern ring is then fixed on before snap ring.
One is equipped in tube channel to be used for the fixed pin of pouch correcting, the same fixed pin of pouch nipple, tube channel
It passes through inside pedicle nail and is fixed in pedicle nail together, before pouch and pouch nipple protrude from pedicle nail
End, fixed pin pass through pedicle nail and pouch nipple and are inserted in the fixing head of pouch, form the correcting knot to pouch
Structure takes out after completing correcting.
Further, the tail end of fixed pin is fixed with screwed fixed adapter, and it is logical that fixed adapter is fixed on one
On road pipe fitting, channel pipe fitting is fixed on the tail end of tube channel.It can be more convenient by channel pipe fitting and fixed adapter
Ground is operated.
Firstly, nail pedicle fix is penetrated on bone and then by pouch.Pouch, which is fixed on, to be spirally connected with tube channel
On pouch nipple, and by fixed pin by its correcting.After installing, the snap ring being arranged on pouch nipple can be bounced,
Tube channel is set not take pouch nipple out of when taking out, i.e. pouch and pedicle nail has reached stationary state.
The utility model is led by being fixed on pouch on the pouch nipple being spirally connected with tube channel with fixed pin
Just, it then by the cooperation of tube channel by pouch nipple and pouch and nail pedicle fix, can achieve so preferably
Space is cleared up, and solves the problems, such as that silica gel balloon urinary is easy to pierce through and may need passage-opening awl together with silica gel balloon urinary
The problem of withdrawal is worn back again；In addition, pouch can effectively limit the flowing of bone cement, making, which will not flow out in bone cement, touches nerve,
More important solution bone density is bad, locks pedicle nail and causes loosening not tight and fierceness or moment huge be wound that can take off again
The situations such as fall.
