Tool axial direction moves forward or back；
Step 4: clamping and is implanted into intervertebral motion retaining device, first rotation knob, and driving supporting rod is advanced axially relative,
Clamping limb is in open configuration, then, implantation instrument clamping bootstrap block is deep into intervertebral motion retaining device or more bone plate
In gap, to determine and gripper hook is guided to clamp, gripper hook is deep into intervertebral motion along clamping guidance Block direction and retains dress
The opening zone end of upper and lower bone plate is set, at this point, the gap between clamping bootstrap block and upper and lower gripper hook is just fastened on up and down
On bone plate, further ensure that accuracy, the reliability of clamping, then reversely rotate knob, at the same entire implantation instrument slightly to
Intervertebral motion retaining device direction is mobile, until closure clamps clamping limb inside under the squeezing action of holding rod, clamping is hooked into
Enter pinch zones, firmly clamped at this point, intervertebral motion retaining device is implanted instrument, holds implantation instrument and protect entire intervertebral motion
It stays device to be implanted to operation presumptive area, that is, completes the clamping and implantation of intervertebral motion retaining device；
Step 5: unclamping intervertebral motion retaining device, withdraw from implantation instrument, rotate knob, at the same hold implantation instrument to
Direction far from intervertebral motion retaining device is moved slightly, until clamping limb opens, gripper hook returns to opening zone, can extract plant out
Enter instrument, is properly completed the implantation of intervertebral motion retaining device.
The invention has the benefit that
1. intervertebral motion retaining device the utility model has the advantages that
(1) present invention using height biomimetic features design, based on to 2000 health Chinese backbone MRI images measurement,
Analysis, research, it is ensured that upper and lower bone plate sagittal facial contour, footmark facial contour can more preferably match with corpus vertebrae bone shape,
And lower bone plate is even more unique outer rim beveling plane for being equipped with protection uncovertebral joint or circular arc, retains dress compared to traditional intervertebral motion
It sets, the contact area of corresponding intrument and vertebral bone of the present invention is bigger, can effectively facilitate Bone Ingrowth healing, and can effectively reduce hand
Centrum amount of bone resection in art retains vertebral bone to greatest extent, simplifies surgical procedure, reduces operating difficulty.
(2) bone plate holding tank is entirely located inside bone plate i.e. using embedded design, instrument the present invention up and down
Gripper hook enters after holding tank clamping, the outer thickness constraints plus bone plate above and below intervertebral motion retaining device, it is ensured that intervertebral
Movement retaining device is not in the movement in direction up and down, can effectively avoid traditional intervertebral motion retaining device and clamps not strongly
Gu there are the major defects such as the loosening of intervertebral motion retaining device, displacement, abjection in implantation process.
(3) bone plate clamping slot structure is located on the inside of bone plate rear end face the present invention up and down, relative to other intervertebral motions
Retain the design that holding tank is placed on intervertebral motion retaining device left and right sides by intervertebral motion retaining device, the present invention is clamping
And unclamp intervertebral motion retaining device when implantation instrument all directions without departing from the size of intervertebral motion retaining device
Range, can effectively reduce window space of performing the operation needed for surgical procedure, and doctor can be effectively reduced in lesser operation window
The operative incision of surgical procedure difficulty, generation is smaller, can effectively reduce operation healing time.
2. the guiding implantation instrument of intervertebral motion retaining device the utility model has the advantages that
(1) present invention initially enters intervertebral motion reservation using clamping guiding design, supporting rod front end clamping bootstrap block
Device among synthetism sheet separation, enters correctly into holding tank region for gripper hook and provides accurate direction guidance, it is ensured that clamping up and down
Process settles at one go, rapid and simple, effectively avoids needing in traditional implantation instrument intervertebral motion retaining device clamping process constantly
The drawbacks of attempting alignment or needing extra means auxiliary alignment.
(2) the rotary motion confinement section of supporting rod of the present invention can effectively prevent implantation instrument knob rotate when supporting rod with
It rotates therewith, and then realizes the axial movement by knob translating rotation for supporting rod, use it compared to traditional instrument
His supplementary structure structure such as pin shaft etc. prevents supporting rod from rotating, rotary motion confinement section of the present invention and supporting rod other structures one
Change design on supporting rod, easy to process, effect is reliable, avoids structural failure wind caused by implantation instrument structure excessively complexity
The excessive drawback in danger.
(3) holding rod configuration design of the present invention is designed using biomimetic features, and shape is in four continuous ring shapes, is performed the operation
Four fingers, which can all be held, in journey is fixed on implantation instrument, and traditional implantation instrument is avoided not have grip portions or gripping
Part it is tiny it is smooth be not easy to operation doctor use and effectively firmly the disadvantages of.
(4) present invention is equipped with elastic telescopic ring and realizes relative motion between holding rod and knob, independent elastic telescopic ring
Structure, especially tapered telescopic section easy to process, is connected through a screw thread and is securely fixed in knob, be easily installed, and fixed
Effect is reliable.
3. the method for implantation of the guiding implantation instrument of intervertebral motion retaining device the utility model has the advantages that
(1) implantation instrument installation of the present invention is simple to operation, and guiding designs so that implantation instrument and intervertebral motion retain
Device docking operation is simple and direct efficiently, and unique holding tank and gripper hook design can effectively ensure that implantation instrument clamps intervertebral
It is solid and reliable in transfer process after movement retaining device, it is not in any opposite between intervertebral motion retaining device component
It is mobile.
(2) since implantation instrument is integrated apparatus in implantation process, intervertebral motion retaining device is implanted to the present invention
The latter step in position is withdrawn from, and is not needed additional auxiliary instrument or is withdrawn from by different level, and surgical procedure is simplified, and saves operating time.
(3) initially to during the entire process of completing implantation, implantation instrument clamping head is always positioned at intervertebral fortune for present invention implantation
Dynamic retaining device is up and down in extreme azimuth, without departing from intervertebral motion retaining device size range outside so that surgical procedure
In open up and be possibly realized with the comparable operation window of intervertebral motion retaining device size, effectively avoid traditional intervertebral motion from retaining dress
It sets larger window of performing the operation in implantation process, increase operating difficulty, extend the drawbacks such as operating time, surgical wound healing time length.
