Description
Technical field
The utility model relates to the field of medical instrument technology, in particular to a kind of anterior approach vertebra localization device.
Background technique
The anterior approach of cervical vertebra requires Fluoroscopy location in art, to determine the segment of operation.And traditional localization method is logical
It is often after staying tail using injection needle bending or the pilot pin of long-tail being stayed to be inserted into interverbebral disc, X-ray examination positioning to be carried out, in positioning operation
When, injection needle bending stays tail or the positioning of long-tail is stayed to be needled into interverbebral disc, and when due to X-ray examination, come loose drag hook esophagus air flue
And return is organized in inside, holds plus pilot pin is unmanned, tends to pilot pin occur to shift and skids off intervertenral space, neck easily occurs
The damage of esophagus tracheae and big blood vessel causes great security risk to clinical operation.In addition, domestic and foreign scholars confirm
If injection needle bending stays tail or the pilot pin of long-tail is stayed accidentally to be placed in the interverbebral disc of No operation segment, it is easy to occur this in the later period
There is Adjacent segment degeneration acceleration in regression after the damage of interverbebral disc, and ASD after operation of spondylosis is caused to occur to influence late result,
Even some patientss need re-treatm ent.
The anterior approach vertebra localization device that we design, positioning operation is convenient and efficient, accurate firm, and easily implantation easily takes
Out, the shakiness for staying long-tail pilot pin interverbebral disc to position in the past is avoided easily to shift the drawbacks of causing secondary damage.Take undercut mark without
It positions, is effectively prevented during Fluoroscopy location to may esophagus air flue and Cervical Vessels in the locator implantation centrum of blocking
Damage, vertebra localization avoids the possibility that interverbebral disc positioning causes artificial acceleration intervertebral regression, while vertebra localization hole can
Directly damage of the operation to centrum itself is effectively reduced using throat dilator.

The anterior approach vertebra localization device of the utility model embodiment is described in detail with reference to the accompanying drawings.
As shown in Figures 1 to 4, according to the anterior approach vertebra localization device of the utility model embodiment, including locator 10
With position manipulator 20, the position manipulator 20 is detachably connected with locator 10, to will be determined by position manipulator 20
Position device 10, which is inserted into anterior approach centrum, carries out Fluoroscopy location.
Specifically, the locator 10 includes pilot pin 11 and the interconnecting piece 12 set on 11 top of pilot pin, the company
Socket part 12 is equipped with a threaded hole 13 far from the end face center of the pilot pin 11；The position manipulator 20 include handle 21 and
The body of rod 22 connecting with the handle 21, the end of the body of rod 22 are provided with the thread head 23 being adapted to the threaded hole 13,
The position manipulator 20 is detachably connected by the cooperation of the thread head 23 and the threaded hole 13 with the locator 10
It connects.
According to the anterior approach vertebra localization device of the present embodiment, needing to position in use, first by the screw thread of locator 10
Hole 13 is tightened on the thread head 23 of position manipulator 20, so that locator 10 is fixed on position manipulator 20, at this time
The pilot pin 11 of locator 10 is inserted into anterior approach centrum by holding position manipulator 20, and will be determined after stationary positioned needle 11
Bit manipulation device 20 is removed from spiral on the interconnecting piece 12 of pilot pin 11, then carries out the positioning of C arm X-ray perspective, positional operand in art
It is convenient and efficient, accurate firm to make, and easily implantation is easily taken out, and the shakiness for staying long-tail pilot pin interverbebral disc to position in the past easily displacement is avoided to make
The drawbacks of at secondary damage.It takes in the unobstructed locator implantation centrum of undercut mark and positions, effectively prevent Fluoroscopy location mistake
To the damage of possible esophagus air flue and Cervical Vessels in journey, vertebra localization avoids interverbebral disc positioning and causes artificial acceleration vertebra
Between regression possibility, while vertebra localization hole can be used directly throat dilator and effectively reduce operation itself to the damage of centrum
Wound.
It should be noted that the diameter of pilot pin 11 is 1.5mm, end is cutting-edge structure, and length can be there are many specification
(such as 10mm or 12mm etc.) can prevent pilot pin 11 from entering too when pilot pin 11 is inserted by the effect of interconnecting piece 12
It is deep, play the role of limit deeply, damages esophagus and tracheae to avoid pilot pin 11.
Further, the interconnecting piece 12 is the flat structure vertical with the pilot pin 11, and is square structure,
At least two symmetrical bayonets 14 are provided on side wall.In the present embodiment, in the middle position difference of 12 4 side wall of interconnecting piece
It is recessed to have a bayonet 14.
The anterior approach vertebra localization device of the utility model further includes having clamper (not shown), and the clamper is using general
Logical operation gripper clamp, using clamper by clamping two bayonets 14 of the interconnecting piece 12 with by the locator
10 is fixed.That is, passing through clamping after the pilot pin 11 of locator 10 is inserted into anterior approach centrum by position manipulator 20
Device is clamped in opposite two bayonets 14 of interconnecting piece 12, and locator 10 is fixed, at this time can be by position manipulator 20 from even
It screws out and takes away in the threaded hole 13 of socket part 12；In addition, can directly be pulled out by gripper locator 10 after completing positioning
Out, locator 10 easily takes out.
In one embodiment of the utility model, the handle 21 is integrally formed with the body of rod 22, and on the handle 21
It is arranged with an antiskid glue sleeve 24, the outer surface of the antiskid glue sleeve 24 is provided with anti-skid chequer.It is fixed so as to be held convenient for operator
Locator 10 is inserted into anterior approach centrum by bit manipulation device 20, is made more reliable and more stable in position fixing process.In other embodiments,
Thread head 23 is that the external screw thread being adapted to by the end peripheral wall setting in the body of rod 22 with threaded hole 13 is formed by.
Preferably, the distal end faces of the handle 21 are the plane 25 vertical with the body of rod 22, can so determine holding
When locator 10 is inserted into anterior approach centrum by bit manipulation device 20, the plane 25 of 21 end of handle is gently tapped by bone hammer, so that
The needle point of pilot pin 11 enters centrum appropriate depth, and pressure applied is uneven when avoiding hand-held insertion.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model
Transformation, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
