Abstract
The invention discloses a kind of skeletal grains to clog equipment, is used for spinal vertebral fusion, and including the casing with hollow channel and propelling piece compatible with the casing for holding skeletal grain, propelling piece is configured in casing, pushes skeletal grain is mobile to complete filling.Beneficial effects of the present invention: skeletal grain can be placed in the hollow channel of casing by one end of not curved surface before surgery.When vertebral fusion needs skeletal grain, insert the cannula into the gap between centrum.Curved surface and be connected to casing external peripheral surface protect the wing to can protect nerve root from surgical injury.The lateral margin of curved surface is tightly attached to the bottom of centrum, plays the role of fixing pipe body position；Then it is pushed into casing from the same end by propelling piece, skeletal grain is pushed among vertebral plate；The efficiency for improving filling saves a large amount of operating time, reduces the probability of patient's infection.
Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to a kind of skeletal grain filling for spinal vertebral fusion to set
It is standby.
Background technique
Statement in this part merely provides background information related with present disclosure, thereby increases and it is possible to not constitute
The prior art.
When requiring vertebral fusion in spinal operation, need to be inserted into bone material between centrum, but because bone material is non-
Chang little Qi partial size is less than 5mm, therefore interleaves in centrum and be not easy into bone material, and there are no standards for spinal interbody fusion operation at present
Interbody fusion skeletal grain filling and nerve root protective device.
Surgeon is generally using tweezers clamping bone material and one piece one piece is put into intervertebral in the prior art, but this
It is inconvenient, and more time can be spent, it is well known that the infected probability of the longer patient of operating time is bigger；While by
It is sharper in tweezers, and operating area is very close from spinal cord and nerve root, it is easy to occur unnecessary nerve damage in bone grafting
Wound.
Therefore the prior art has much room for improvement and develops.
Summary of the invention
The technical problem to be solved in the present invention is to provide it is a kind of filling it is high-efficient, expend the time it is few, reduce patient infection
Skeletal grain clogs equipment.
The technical solution of the invention is as follows: a kind of skeletal grain filling equipment is used for spinal vertebral fusion, including for containing
The casing with hollow channel and propelling piece compatible with the casing of skeletal grain are put, propelling piece configures in casing, pushes bone
Grain is mobile to complete filling.
Described sleeve pipe one end is configured with two curved surfaces of left and right.
The curved surface is one section in annulus.
Further include the protection wing perpendicular to casing axis, the protection wing be connected to described sleeve pipe outer circumference surface and with the song
Face is located at the same end of casing.
Described sleeve pipe side wall in axial direction offers the observation window for being connected to its hollow channel, is covered on the observation window
Bright part.
The Transparent Parts are PVC film.
The propelling piece includes that lever section and filling section, the lever section diameter are greater than the diameter of the hollow channel.
The length of the filling section is greater than the length of hollow channel.
Diameter of the diameter of the hollow channel slightly larger than the filling section.
Beneficial effects of the present invention:
Using the above structure, skeletal grain can be placed in the hollow channel of casing by one end of not curved surface before surgery
In.When vertebral fusion needs skeletal grain, will be finished between the casing insertion centrum of bone grafting grain by instrument nurse filling in advance
Gap in.Curved surface and be connected to casing external peripheral surface protect the wing to can protect nerve root from surgical injury.Curved surface
Lateral margin is tightly attached to the bottom of centrum, plays the role of fixing pipe body position；Then it is pushed into casing from the same end by propelling piece, bone
Grain is pushed into intervertenral space；The efficiency for improving filling saves a large amount of operating time, reduces the probability of patient's infection, exempts from
Unnecessary nerve root and spinal cord injury may.

Specific embodiment
Embodiment:
Refering to fig. 1 to Fig. 5；The present invention discloses a kind of skeletal grain filling equipment, is used for spinal vertebral fusion, including for containing
The casing 1 with hollow channel 11 and propelling piece 2 compatible with the casing 1 of skeletal grain are put, propelling piece 2 configures in casing 1,
Push skeletal grain is mobile to complete filling.
1 one end of described sleeve pipe is configured with two curved surfaces 3 of left and right.
The curved surface 3 is one section in annulus.
Further include the protection wing 4 perpendicular to 1 axis of casing, the protection wing 4 be connected to 1 outer circumference surface of described sleeve pipe and with institute
State the same end that curved surface is located at casing 1.
1 side wall of described sleeve pipe in axial direction offers the observation window 5 for being connected to its hollow channel, is covered on the observation window
Transparent Parts.
The Transparent Parts are PVC film, and the PVC film is consistent with casing pipe thickness, and the film is transparent can see
Bone grafting grain clogs situation.
The propelling piece 2 includes that lever section 21 and filling section 22,21 diameter of lever section are greater than the hollow channel
Diameter.
The length of the filling section 22 is greater than the length of hollow channel 11.
Diameter of the diameter of the hollow channel 11 slightly larger than the filling section 22.
In particular it is object of the present invention to which skeletal grain to be more easily packed to the centrum that need to be merged, make in the present invention
Material includes polyvinyl chloride (PVC), brass and timber.Casing 1 is 150mm long, internal diameter 10mm, wall thickness 1mm.The casing conduct
The container of bone material can be got ready before surgery.One end of casing is designed to two curved surfaces, and refering to Fig. 2, it is to lose
The annulus of two block portions point.The protection wing of casing axis is perpendicular on the outside of two curved surfaces.Curved surface and the protection wing play patron saint
The effect of warp.The other end of casing be it is open, for placing skeletal grain, be also used for push-in propelling piece, propelling piece of the invention is
Clog rod.The material of the main structure of casing is brass.On tube wall, a rectangle observation window instead PVC are opened up
Film, such surgeon can see the amount of bone material in pipe.Clog rod shape be two cylinders, one end tubbiness, directly
Diameter 50mm, long 100mm are wooden lever.The other end is elongated, diameter 9.8mm, long 190mm, for the part for being pushed into casing.
Use process of the invention: skeletal grain can be placed in the hollow logical of casing by one end of not curved surface before surgery
In road.When vertebral fusion needs skeletal grain, insert the cannula into the gap between centrum.Curved surface and it is connected to casing outer circle weekly form
The wing is protected to can protect nerve root from surgical injury in face.The lateral margin of curved surface is tightly attached to the bottom of centrum, plays fixed tube body
The effect of position；Then it is pushed into casing from the same end by propelling piece, skeletal grain is pushed among vertebral plate；Improve the effect of filling
Rate saves a large amount of operating time, the probability of patient's infection is reduced, to protect nerve root and spinal cord.
