Description
Technical field
The utility model relates to a kind of medical instruments more particularly to a kind of thoracic and lumbar vertebral posterior to look at lower percutaneous cervical arc root screw straight
Percutaneous cervical arc root passage-opening awl when implantation surgery.
Background technique
Currently, under thoracic and lumbar vertebral posterior direct-view when percutaneous cervical arc root screw implantation surgery, with common passage-opening awl in pedicle of vertebral arch
Inside push cancellous bone open, nail channel is set in production.When carrying out production channel with this instrument, it is located at before passage-opening awl due to length scale
Section can not read passage-opening awl and enter depth in pedicle of vertebral arch because soft tissue blocks by vertebra, position locating for passage-opening awl tip when causing to have an X-rayed
It sets bad, often needs percentage regulation and to have an X-rayed repeatedly repeatedly, it is good with the channel position made by ensuring.Furthermore extract open circuit
When being inserted into seal wire after cone, Chang Yinwei surrounding soft tissue is blocked, and is caused seal wire insertion difficult, need to be found pedicle channel repeatedly, make
Cumbersome, operating time extends, perspective number increases, and brings pain to patient.
Summary of the invention
The utility model is after solving to extract passage-opening awl in the prior art, to be inserted into seal wire, cumbersome inconvenience, operation
Time is long, and the problem of pain is brought to patient.
The utility model aim is to provide one kind, and percutaneous cervical arc root screw merging production, can when setting nail channel under direct-view
It easier completes, rapid operation, safe and accurate, quick pediculus arcus vertebrae opening cone.
Following technical scheme is used to achieve the above object:
A kind of percutaneous cervical arc root passage-opening awl, including a wooden balanced handle and a round metal bars, round metal bars tail end
It is embedded into handle, round metal bars have flat front end, and round metal bars are equipped with length scale, and round metal bars tail end is arranged in hand
Handle center location, wood handle is equipped with the straight line pylone parallel with round metal bars, the through-hole eccentric setting, and through-hole lower end is tight
Metal pole.
The utility model easy to operate, time saving and energy saving, safety and precise when pedicle screw duct makes.
Preferably, the straight line pylone is fine aperture, and aperture is only passed through for wire guide.
Further, round metal bars are equipped with seal wire slot, and seal wire groove top point is docked with straight line pylone lower end.
Preferably, the flat front end of round metal bars is that V-butt processed is formed on barred body.
Detailed description of the invention

In figure: handle 1, round metal bars 2, length scale 3, flat front end 4, through-hole 5, seal wire slot 6.
Specific embodiment
The utility model is the cone of pediculus arcus vertebrae opening used in pedicle screw implantation surgery under a kind of direct-view.See Fig. 1,2,
3, which is made of wood handle 1, round metal bars 2.Wood handle 1 is rounded, is conducive to rotate left and right handle in art.Gold
Belong to pole 2 and be mounted to 1 center of wood handle, makes the Concentric rotation therewith of round metal bars 2 when rotating wood handle 1.In round metal bars 2
There is length scale 3, every length scale 3 was conducive to convenient reading scale in art around round metal bars 2 one weeks.Round metal bars 2 have
There is flat front end 4, is protruded into art in pedicle of vertebral arch in cancellous bone.
The setting of 2 tail end of round metal bars is equipped with the straight line parallel with round metal bars 2 in 1 handle center location, wood handle 1
Round metal bars 2 are close in through-hole 5,5 eccentric setting of through-hole, 5 lower end of through-hole.
The straight line pylone 5 is fine aperture, and aperture is only passed through for wire guide.Further, as shown in Figure 4,5, 6,
Round metal bars 2 are equipped with seal wire slot 6, and 6 vertex of seal wire slot is docked with 5 lower end of straight line pylone.The flat front end 4 of round metal bars is V
Shape groove, groove face can be plane, be also possible to arcwall face.Seal wire slot 6 is located in slope surface.
The utility model percutaneous cervical arc root screw in the case where implementing direct-view is placed in, when nail channel is set in production, this passage-opening awl is flat
Flat front end is put into pedicle of vertebral arch, is read and is entered depth；Then handle is rotated left and right, cancellous bone in pedicle of vertebral arch is pushed open；Third step,
When passage-opening awl front end enters certain depth in pedicle of vertebral arch, positive side position perspective is carried out, observe passage-opening awl front position and judges to set
Whether nail channel is good；4th step continues that passage-opening awl is promoted to enter front end in centrum；5th step slowly extracts passage-opening awl,
Percutaneous cervical arc root screw seal wire is inserted into the hole on handle simultaneously；6th step extracts passage-opening awl, while by seal wire along round metal bars
It is inserted into pedicle channel.
The utility model is backing out the front lower seal wire of road cone, provides guiding for seal wire, makes pedicle screw duct production behaviour
Make simpler, easily implementation.Lower seal wire process is time saving and energy saving, safety and precise.
It is as follows to implement the process once performed the operation using this passage-opening awl:
Lower label pedicle of lumbar vertebral arch skin projection, the longitudinal incision skin at pedicle of vertebral arch projection outer rim are had an X-rayed in patient lies prone position
Skin about 1.5cm.
Subcutaneous fat, lumbodorsal fascia are successively cut, reaches zygapophysial joint from blunt separation between paraspinal muscle flesh, small drag hook is to two
Side retracts soft tissue.
Light is adjusted, is open under direct-view in articular process outer rim and transverse process root intersection, passage-opening awl front end is put into opening
Place reads scale at skin.
Passage-opening awl is adjusted according to preoperative measurement angle, handle is rotated left and right, makes passage-opening awl front end in pedicle of vertebral arch cancellous bone
It moves ahead.
When passage-opening awl front end reaches pedicle of vertebral arch and centrum intersection (preoperative CT measures pedicle of vertebral arch length), C-arm perspective
L spine ap & lat, side position confirmation passage-opening awl front end reach pedicle of vertebral arch and centrum intersection.
Normotopia confirmation passage-opening awl front end does not wear out pedicle of vertebral arch inner wall, and after confirmed position is good, passage-opening awl is continued forward
Rotation promotes 1.5cm to enter in centrum.
Perspective lateral lumber spine confirmation open circuit coning angle, position is good again, slowly extracts passage-opening awl, while by percutaneous vertebral arch
Root screw wire guide is inserted into handle aperture, and seal wire is made to be close to passage-opening awl metal bar downlink.
Passage-opening awl is exited on one side, promotes seal wire on one side, enters seal wire accurately in pedicle channel, is screwed into suitably along seal wire
The percutaneous cervical arc root screw of length.
Continue remaining operating procedure.
