As shown in Figure 1 to Figure 3, the drag hook component for interbody fusion of the present embodiment includes: two drag hook bodies 100；
Drag hook body 100 includes: the arm-tie 110 being connected and pull handle 120, and one end of pull handle 120 is connected with one end of arm-tie 110,
It is inner side that arm-tie 110 arranges the side of pull handle 120, pull handle 120 relative to arm-tie 110 for being obliquely installed；Outside arm-tie 110
Side 111 is oppositely arranged with the medial surface 112 of arm-tie 110, and the lateral surface 111 of arm-tie 110 is provided with abutment sleeve 200,
In the present embodiment, the quantity of abutment sleeve 200 is two.
Determining lumbar motion segment, and cut skin, subcutaneous fat, separate paravertebral muscles, retract nerve root after, by two drag hooks
The arm-tie 110 of body 100 inserts in the muscle of separation respectively, and two arm-ties 110 are oppositely arranged, and two pull handles 120 are also phases
To setting；Medical personnel pull out two pull handles being oppositely arranged 120, make muscle separate further；Again by locating pin 610
Penetrating in abutment sleeve 200, and locating pin 610 be fixed on vertebral body, the interval region formed between two arm-ties 110 is
Operation path 500, after operation path 500 is formed, can carry out remaining operation technique.Owing to arm-tie 110 is a plate body,
So when inserting in the muscle separated, avoiding big blood vessel easily, thus prevent the accidental injury to big blood vessel.Locating pin 610
Can be firmly fixed on vertebral body, operation path 500 space making formation is bigger.
During in order to make the present invention use, medical personnel will not be stopped by patient body when pulling pull handle 120, makes the interior of pull handle 120
Formed by the junction of the medial surface 112 of side 122 and arm-tie 110, angle α is more than or equal to 90 degree, in the present embodiment, and pull handle
Angle formed by the medial surface 122 of 120 and the junction of the medial surface 112 of arm-tie 110 is 95 degree, and this angle is more convenient for medical care
Librarian use drag hook body 100.
Arm-tie 110 is arc, and the arm-tie 110 of arc is for bend towards pull handle 120, and this structure makes arm-tie 110 to fit
The muscle of human body, it is simple to when pulling pull handle 120, makes muscle separate.
Arm-tie 110 includes the insertion plate body 113 being connected and extends plate body 114, extends plate body 114 and is connected with pull handle 120,
Abutment sleeve 200 is arranged on the lateral surface inserting plate body 113, after this structure makes arm-tie 110 in the muscle inserting separation,
Insert plate body 113 and be in the lower section extending plate body 114, the most just make abutment sleeve 200 be in the bottom of arm-tie 110, it is simple to be fixed
Position nail 610 penetrates abutment sleeve 200 and is fixed on vertebral body.
In order to avoid the screw thread of locating pin 610 damages tissue, abutment sleeve 200 includes support tube 210 and is arranged at support
Cylinder positioning tube 220 within 210, positioning tube 220 can be in support tube 210, along moving axially of support tube 210, fixed
Position nail 610 penetrates in positioning tube 220, and during locating pin 610 moves down, positioning tube 220 can be along with locating pin
610 move down, and locating pin 610 is isolated from the outside by positioning tube 220.Locating pin 610 includes nail head 611 and nail
Bar portion 612, the length of nail shank 612 is more than the length of positioning tube 220, to ensure that nail shank 612 can penetrate vertebral body
In.
Extending middle interconnecting piece 1141 and light source carrier 1142 that plate body 114 includes being connected, middle interconnecting piece 1141 is with slotting
Entering plate body 113 to connect, light source carrier 1142 is connected with pull handle 120, and the lateral surface of light source carrier 1142 is provided with light source
Mounting cylinder 300.Before this drag hook component uses, light source component can be installed and put in light source mounting cylinder 300, in the present embodiment, light
The quantity of source mounting cylinder 300 is two.
Light source carrier 1142 and pull handle 120 junction are set to fillet, and this structure makes drag hook body 100 preferably fit human body
Muscle.
Drag hook body 100 also includes that positive stop hook 400, positive stop hook 400 are arranged on one end away from arm-tie 110 of pull handle 120；
Owing to medical personnel are holding pull handle 120, and during pulling out pull handle 120, hands is easily separated from pull handle 120, arranges
Positive stop hook 400, it is possible to opponent plays position-limiting action, prevents hands from departing from pull handle 120.
Positive stop hook 400 extends from the lateral surface 121 of pull handle 120 to one end of the close arm-tie 110 of pull handle 120, and this structure makes
The hands that hold pull handle 120 can be snapped in positive stop hook 400, it is simple to medical personnel hold pull handle 120, separating muscle.
The invention still further relates to the using method of a kind of drag hook component for interbody fusion, comprise the following steps:
1) determine lumbar motion segment, take about 12cm by center line, long incision 2.5-3cm, 45 ° towards vertebral body, at successively percutaneous incision
Skin, subcutaneous fat, blunt separation paravertebral muscles, retract nerve root after, two arm-ties 110 are inserted respectively the muscle of separation
In, two arm-ties 110 are oppositely arranged；Medical personnel hold two pull handles being oppositely arranged 120, and pull out two
Individual pull handle 120, makes muscle separate further；
2) four locating pins 610 being respectively penetrated in the positioning tube 220 of corresponding abutment sleeve 200, locating pin 610 drives fixed
Position cylinder 220 moves downwardly together, and screwdriver 700 turns the nail head 611 of locating pin 610, locating pin 610 is fixed on
On vertebral body, the interval region formed between two arm-ties 110 is operation path 500.
The present invention can be prevented effectively from the accidental injury to big blood vessel, easy and simple to handle, and in art, the drag hook component of the present invention can be firm
Be fixed on vertebral body, highly stable, expansive space is relatively big, and beneficially intervertebral processes and implants the operation of fusion device.To sum up, this
Bright effectively overcome various shortcoming of the prior art and have high industrial utilization.
The principle of above-described embodiment only illustrative present invention and effect thereof, not for limiting the present invention.Any it is familiar with this skill
Above-described embodiment all can be modified under the spirit and the scope of the present invention or change by the personage of art.Therefore, such as
All that in art, tool usually intellectual is completed under without departing from disclosed spirit and technological thought etc.
Effect is modified or changes, and must be contained by the claim of the present invention.
