Abstract
A kind of minimally invasive screw-pushing type spine graft device, including funnel, tube channel, thread spindle and handle, the funnel be it is with a scale detachable, its tail end of the tube channel has internal screw thread, and there are lever in two sides, the thread spindle head end is spindle nose, middle part has screw thread, and tail end has square connector, the internal screw thread matching of thread spindle and tube channel tail end, it is connected through a screw thread and protrudes into tube channel, the handle is installed on screw thread shaft tail end.Its advantage is that structure is simple, easy to use, it can be improved bone grafting speed, save operating time, operation risk, quantization bone grafting quantity are reduced, mitigates the labor intensity of hand, precisely carry out narrow depth in position bone grafting, solve the problems, such as that foramen intervertebrale lens operation can not bone grafting.
Description
Technical field
The utility model relates to the device of bone grafting, espespecially a kind of minimally invasive screw-pushing type spine graft are carried out in bone surgery
Device.
Background technique
The intervertebral fusion of clinical spinal operation, the filling in the centrum gap after compression fracture of the spine reset, foramen intervertebrale lens hand
The intervertebral fusion of art, the various lesions such as wound, inflammation, bone tumour cause bone defect to be both needed to carry out bone grafting treatment.Home and abroad is public
Recognizing most popular method is autologous transplanting bone or homogeneous allogenic bone, broken particle shape need to be stung into when being implanted into these sclerotin, at present ridge
There are two types of methods for column bone grafting one is with tweezers, by more than implantation bone defects of skeletal grain, this method for implantation is time-consuming and laborious, and
And skeletal grain is easy to be scattered and dissipate bone grafting in leakage its elsewhere, especially depths bone grafting such as backbone intervertenral space and is easy to cause dural sac, mind
It is pressurized through root.Another kind is to carry out bone grafting (Fig. 3) by bone grafting funnel communicating passage pipe, is carried out when intervertenral space bone grafting in tube channel
Diameter is necessarily less than 8mm, pedicle Vertebral body graft is necessarily less than 5mm, thus when bone grafting also can only many pass through tube channel plant
Entering in intervertenral space or centrum, speed is very slow, if primary, being put into more skeletal grains squeezes into bone grafting position by lead rod simultaneously, by
It is very big in frictional force, it can not be directly pushed by hand to which bone grafting cannot succeed.Spinal disease operative treatment application pedicle of vertebral arch
Internal fixation technology is restored to normal position by decompression and by centrum, releases the symptoms such as pain in the loins and the skelagia of patient, and will
Centrum is merged with adjacent vertebral.Any internal fixation device cannot all work forever, because metal can be sent out with bone interface
Raw to loosen, fusion device will appear the problems such as collapsing, deviating from.Sufficiently, efficiently bone grafting with the raising for ensuring fusion rate is still not
Negligible problem.Because the bone grafting entrance range of intervertenral space is very narrow and the reasons such as intervertenral space bone grafting range is deeper, operation
The problems such as middle intervertenral space bone grafting amount is few are not solved always.In recent years the minimally invasive foramen intervertebrale lens technology risen is due to logical without good tool
It crosses aperture mirror channel and carries out bone grafting to limit the further development of aperture mirror treatment.
Summary of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of minimally invasive screw-pushing type spine grafts
Device.It aims to solve the problem that the prior art there are bone grafting speed in spinal operation slow, bone grafting amount and can not clearly quantify, surgical doctor labour
Intensity is big, be easy to damage depressurized under dural sac, nerve root, foramen intervertebrale lens after the disadvantages of can not carrying out bone grafting.
The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of minimally invasive screw-pushing type backbone
Bone grafting instrument, it is characterised in that: including funnel, tube channel, thread spindle and handle, the tube channel is removably mounted under funnel
Side, internal screw thread is arranged at bottom, outside have lever, the thread spindle front end is spindle nose, and middle part has screw thread, and there is connection at rear portion
Internal screw thread below head, thread spindle and tube channel matches, and is connected through a screw thread and protrudes into tube channel, the handle is installed on screw thread
Shaft rear end.
There is scale on the funnel.The number of bone grafting amount can be quantified.
The connector is square connector.Convenient for being connected with handle and being not easy to skid.
The handle is ratchet handle.It is easy to operate, laborsaving.
The beneficial effects of the utility model are: structure is simple, easy to use, when can be improved bone grafting speed, saving operation
Between, operation risk, quantization bone grafting quantity are reduced, mitigates the labor intensity of hand, precisely carry out narrow depth in position bone grafting, solve
Foramen intervertebrale lens operation can not bone grafting problem.
Detailed description of the invention
The utility model will be further described with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model, and osseous granules are placed in tube channel by left hand view in advance, and right part of flg is by osseous granules
From tube channel spiral push-in bone grafting.
Fig. 2 is the structural decomposition diagram of the utility model.

Specific embodiment
Referring to attached drawing, a kind of minimally invasive screw-pushing type spine graft device of the utility model, it is characterised in that: including funnel 1,
Tube channel 2, thread spindle 3 and handle 4, the funnel be it is with a scale detachable, described its tail end of tube channel 2 has internal screw thread 24,
There is lever 23 in its two sides, and 3 head end of thread spindle is spindle nose 31, and middle part has screw thread 33, and tail end has square connector 34, screw thread
3 screw thread 33 of axis and the internal screw thread 24 of 2 tail end of tube channel match, and are connected through a screw thread and protrude into tube channel, the handle 4 is installed on
3 square connector 34 of thread spindle.
In the embodiments of the present invention:
The funnel 1 is used cooperatively for detachable convenience with tube channel, have thereon scale 13 can to bone grafting number
Quantified.
The tube channel 2, tail end have internal screw thread 24 to match common completion screw propulsion effect with 3 screw thread 33 of thread spindle.
The thread spindle 3, head end have spindle nose 31 to match with channel bore, spiral shell in screw thread axle thread 33 and tube channel
Screw propulsion effect is completed in the matching of line 24, and tail end is connected with 4 collet 42 of handle for square knuckle 34 and can anti-slip.
