Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of children's intervertebral bone grafting apparatus.
Background technique
In spinal operation, in order to increase the stability of backbone, usually bone graft fusion between row Thoracolumbar disk.Intervertebral bone graft melts
Condensation material can use Invasive lumbar fusion device, autologous bone and homogeneous allogenic bone, since Invasive lumbar fusion device is expensive, homogeneous allogenic bone rejection
React more, therefore many patients require to select to take autologous bone (spinous process and vertebral plate bone that cut off in such as autologous ilium and art) as bone grafting
Material.The implantation of bone material at present commonly uses the broken bone of the clamping such as instrument such as nucleus pulposus clamp and fills in intervertenral space, and this bone grafting mode is deposited
Each bone amount it is few, need to operate repeatedly repeatedly, easy damaged dural sac, be implanted into the shortcomings that broken bone is not concentrated.And existing intervertebral bone graft
The tamper of device is by bone material push-in bone grafting and when tamping, casing front end is completely open, and tamper is prominent when firmly excessive in casing
Broken anterior longitudinal ligament damage abdominal cavity blood vessel and internal organs, and it is firmly too small lower end can be made to block, and influence bone grafting effect.In addition,
When filling broken bone in casing, since lower end is not closed, can only be blocked using hand, the broken bone filling in casing is not firm,
Bone amount loads less, and after hand relieving, is easy to produce leakage.
Utility model content
The purpose of the utility model is to overcome drawbacks described above, provide that a kind of structure is simple, plants using safe children's intervertebral
Bone object can prevent bone grafting instrument from exerting oneself quantum jump anterior longitudinal ligament damage abdominal cavity blood vessel and internal organs, improve children's spinal operation bone grafting
Safety.
The utility model is to achieve the goals above, as follows using technical solution:
A kind of children's intervertebral bone grafting apparatus, including casing and tamper, the closing of described sleeve pipe front end, side wall are equipped with opening,
Casing front end inner cavity forms smooth bevel, and the lower end on inclined-plane and the lower end of sidewall opening are horizontal, and the lever front end of tamper is extended
The body portion of elongated rod-shaped, the end in body portion form the body portion inclined-plane matched with cannula bevel, and the body portion of tamper is inserted into casing
It is fitted close to and slides up and down with union body inner wall.
Leak jacket pipe, the bottom opening of leakproof casing are provided with outside described sleeve pipe, the short end and sleeve side walls of side wall are open
Upper surface it is horizontal, the lower end surface of the long end of side wall and sleeve side walls opening is horizontal or is lower than lower end surface.
Graduation mark is provided on the leakproof sleeve outer wall.
The leakproof sleeve upper end forms handle.
Funnel-shaped structure is formed at described sleeve pipe top, is provided with handle.
Graduation mark is provided on the outer wall of described sleeve pipe, tamper body portion is provided with graduation mark.
The children intervertebral bone grafting apparatus casing front end of the utility model is closed, sidewall opening, the casing when being tamped using tamper
Closed front end stops tamper, so that tamper is not broken through anterior longitudinal ligament damage abdominal cavity blood vessel and internal organs, improves what bone grafting instrument used
Safety, at the same be provided with outside casing leak jacket pipe can prevent from loading and art between leak.
Detailed description of the invention
The structural schematic diagram of Fig. 1 the utility model.
The leakproof casing structural schematic diagram of Fig. 2 the utility model.
The tamper structural schematic diagram of Fig. 3 the utility model.
In figure, 1 leakproof casing, 2 casings, 3 tampers, 11 handles, 12 long ends, 13 short ends, 21 union bodies, 22 funnel-form knots
Structure, 23 inclined-planes, 24 openings, 25 handles, 31 levers, 32 body portions, 33 body portion inclined-planes.
Specific embodiment
As shown in Figure 1-Figure 3, children's intervertebral bone grafting apparatus of the utility model is made of casing 2, tamper 3 and leakproof casing 1,
Funnel-shaped structure 22 is formed at 2 top of casing, is provided with handle 25, the closing of 2 front end of casing, and side wall is equipped with opening 24,
2 front end inner cavity of casing forms smooth bevel 23, and the lower end on inclined-plane 23 and the lower end of sidewall opening 24 are horizontal.The lever 31 of tamper 3
The body portion 32 of elongated rod-shaped is extended in front end, and the end in tamper body portion 32 forms the body portion inclined-plane matched with cannula bevel 23
33, the body portion of tamper 3, which is inserted into casing 2, to be fitted close and slides up and down with 21 inner wall of union body.It is provided on the outer wall of casing 2
Graduation mark, for measuring the broken bone amount in casing 2,3 body portion of tamper is provided with graduation mark and protrudes into casing 2 for measuring tamper body
Depth.
Leak jacket pipe 1, the bottom opening 24 of leakproof casing 1, the short end 13 and sleeve side walls of side wall are provided with outside casing 2
The upper surface of opening 24 is horizontal, and the lower end surface of the long end 12 of side wall and sleeve side walls opening 24 is horizontal or is lower than lower end surface.Leakproof
1 upper end of casing forms handle 11.It is provided with graduation mark on 1 outer wall of leakproof casing, enters depth at bone grafting for measuring casing.
In use, leakproof casing 1 is outside casing, the opening 24 of sleeve side walls is closed at 1 sidewall length end 12 of leakproof casing,
Broken bone is put into casing by 2 upper funnel shape structure 22 of casing, tamper 3, which is inserted into casing 2, applies certain pressure, casing
Broken bone compacting, measures broken bone volume in casing according to 2 EXT scale of casing, bone grafting instrument is inserted at wanted bone grafting, rotation is anti-in 2
Leakage casing 1 is located at 1 side wall short end 13 of leakproof casing at sleeve side walls opening 24, is implanted into appropriate bone to 24 direction of sidewall opening
Afterwards, bone grafting instrument direction is rotated, allows bone grafting instrument opening 24 to the direction for needing bone grafting, continues bone grafting.The utility model structure is simple,
Using safe.
