Description
Technical field
The utility model belongs to clinical medicine, field of spinal surgery, and in particular to a kind of modified form intervertebral fusion with a scale
Bone grafting funnel.
Background technique
Spinal surgery faces a large amount of unstable spine operation at present, it is necessary to intervertebral fusion accessory come to unstable spinal band
Stablize, most commonly used be exactly Invasive lumbar fusion device, but broken bone can be first spread to intervertenral space before Invasive lumbar fusion device implantation, to increase
Add bone grafting area, increases fusion probability.
Because most of operation is all to enter centrum from vertebra side (such as left side), and bone grafting funnel in the market is all straight
, if needing again to be elapsed broken bone block to opposite side with other tool, increasing broken bone implant to opposite side (such as right side)
Operating time and risk；And funnel lacks scale, can not quantify, the depth into intervertenral space (centrum) can only be invisible by rule of thumb
Middle increase risk, if touching the abdominal aorta before intervertenral space (centrum) into too deep, consequence can not be remedied；And current
Bone grafting funnel will be put into broken bone from uppermost enlarged portion, and the bone amount needed in this way is more, and broken bone passes through funnel whole region, road
Journey length is also easy to block.
Utility model content
Purpose of utility model: overcoming the deficiencies of existing technologies, and designs a kind of modified form Interbody fusion funnel with a scale,
Can be directly by broken bone passage to opposite side, bone grafting is abundant；It can quantify the depth that funnel enters centrum, reduce group in front of injected vertebral body
The possibility knitted；Simplify the process that broken bone reaches centrum designated position, saves operating time.
Technical solution: the utility model adopts the following technical solution:
Modified form Interbody fusion funnel with a scale, including straight funnel, elbow, handle, the straight funnel have
Enlarged portion, enlarged portion outer wall side connect the handle, gripping when facilitating operation；The elbow is by elbow top, circular arc
Outlet portion composition, the elbow top is consistent with the axis of straight funnel, and external screw thread is had at the top of the elbow, with the straight leakage
The internal screw thread that the bottom of bucket has closely is connected；The side of the circular arc outlet portion of the elbow is circular arc, and the other side is opening, institute
The maximum width for stating circular arc outlet portion is no more than the diameter of the straight funnel bottom, guarantees ruler when the bone grafting funnel enters centrum
Very little minimum not will lead to bone grafting funnel bottom width and increase and influence bone grafting operation, to reduce the risk of operation；The bone grafting
The outer wall of funnel is equipped with two groups of scales, and first group of scale continues up to the corresponding side of straight funnel since curved bottom
Place, can measure straight funnel and elbow enters the depth of centrum；The opposite side of first group of scale is arranged in second group of scale, from straight leakage
Bucket bottom starts to continue up to the straight funnel side somewhere, after unloading elbow, still can measure the straight funnel and enter
The depth of centrum；And after unloading elbow, the outer wall of the bottom of the straight funnel be it is smooth, still have original funnel function
Can, the bone grafting operation of straight funnel in next step is not influenced.
Preferably, the height at the top of the curved bottom to elbow of the circular arc outlet portion is 1~2cm.
Preferably, the bone grafting funnel also has a poker, the poker be it is rodlike or coniform, for being arrived when bone grafting funnel
Pre-packed broken bone in elbow is ejected after up to predetermined position.
Concrete operation step: first filling broken bone for the elbow, and elbow is threadedly attached to straight funnel bottom, holds
The entire bone grafting funnel is sent into centrum by handle, pays attention to observing the scale on funnel, is pre-positioned when the bone grafting funnel reaches
It postpones, with the broken bone pre-installed in poker ejection elbow, operation terminates, and takes out bone grafting funnel.
The utility model has the beneficial effects that the utility model can install broken bone in elbow in advance, dress bone process is simplified,
Propulsion time of the broken bone in funnel is reduced, broken bone is prevented to be stuck in funnel, and then reduces operation time, reduces bleeding；
And broken bone directly can be sent to designated position in centrum by elbow, bone grafting is abundant；With two rows of scales on bone grafting funnel, at any time
Know that bone grafting funnel enters the depth of centrum, reduce the damage possibility organized in front of centrum, accomplishes to quantify bone grafting amount, precisely plant
Bone reduces the harassing and wrecking to intraspinal tube spinal nerve.

Specific embodiment
In order to keep the purpose of this utility model, technical solution and advantage clearer, with reference to the accompanying drawing and it is embodied
The utility model is described in detail in example.
Such as Fig. 1~4, modified form Interbody fusion funnel with a scale, including straight funnel 1, elbow 2, handle 3 are described straight
Enlarged portion 11 is had at the top of funnel 1, the 11 outer wall side of enlarged portion connects the handle 3, gripping when facilitating operation；It is described curved
First 2 are made of 20, circular arc outlet portion 22 at the top of elbow, and 20 is consistent with the axis of straight funnel 1 at the top of the elbow, and the elbow
Top 20 has external screw thread 21, and the internal screw thread 13 having with the bottom of the straight funnel 1 is closely connected；The circular arc of the elbow 2
The side of outlet portion 22 is circular arc 221, and the other side is opening 222, and the maximum width L of the circular arc outlet portion 22 is no more than described
The diameter D of straight 1 bottom of funnel guarantees that size is minimum when the bone grafting funnel enters centrum, and it is wide not will lead to bone grafting funnel bottom
Degree increases and influences bone grafting operation, to reduce the risk of operation；The outer wall of the bone grafting funnel be equipped with two groups of scales, first
Group scale 12 continues up to the corresponding side somewhere of straight funnel 1 since 221 bottom of circular arc, can measure straight funnel 1 and elbow 2
Into the depth of centrum；The opposite side of first group of scale 12 is arranged in second group of scale 23, continues up since straight 1 bottom of funnel
To the straight funnel 1 side somewhere, after unloading elbow 2, the depth that the straight funnel 1 enters centrum still can be measured；And it unloads
After lower elbow 2, the outer wall of the bottom of the straight funnel 1 be it is smooth, still have original funnel function, not under the influence of one
Walk the bone grafting operation of straight funnel.
221 bottom of circular arc of the circular arc outlet portion 22 at the top of elbow 20 height is 1~2cm.
The bone grafting funnel also has a poker 4, the poker 4 be it is rodlike or coniform, for when bone grafting funnel reach it is pre-
Positioning postpones pre-packed broken bone in ejection elbow 2.
Concrete operation step, such as Fig. 5: first filling broken bone for the elbow 2, and elbow 2 is threadedly attached to straight funnel 1
Bottom holds handle 3 for the entire bone grafting funnel and is sent into centrum, pays attention to observing the scale on bone grafting funnel, when the bone grafting
After funnel reaches predetermined position, the broken bone pre-installed in elbow 2 is ejected with poker 4, operation terminates, and takes out bone grafting funnel.
Above-described specific embodiment, to the purpose of this utility model, technical scheme and beneficial effects carried out into
One step is described in detail.It should be pointed out that being not used to limit the utility model the above is only preferred embodiments of the present invention
Protection scope under the premise of not departing from the utility model structure, can also make for a person skilled in the art
Several modifications and improvements, these improvement also should be regarded as the protection scope of the utility model, these all will not influence the utility model
The effect and patent practicability of implementation.
