Technical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of nothing for spinal operation navigation tracer
Create fixed device.
Background technique
Spinal operation navigation usually obtains patient image in the preoperative or in art, realizes that image guides hand later to be registrated in art
Art.Currently used image bootmode include two dimensional perspective guidance, CT guidance and art in conical beam CT guidance etc..Backbone hand
The displacement of patient caused by any reason or bone structure variation in art are tracked in art navigation by tracer.It is usually that tracer is secured
It is fixed near patients surgery bone structure, acquires under such situation image, the position that navigation system passes through tracer in corresponding art
It sets to realize the image-guided surgery to surgical structure.Tracer fixing means is usually different due to modus operandi, Minimally Invasive Surgery
General pass through percutaneously is fixed, and tracer is then directly clamped or be anchored on the position for closing on bone structure by open surgery.
The effect of tracer ontology is in the course of surgery to provide a coordinate origin for navigation system, and metal clip
Effect is to connect the backbone of tracer ontology and patient, forms a stable rigid connection, prevents in surgical procedure
Coordinate origin is mobile, causes surgical errors.When in use, the opening of a 3-4cm is opened on patient spine first, will be owned
Soft tissue removing, exposes the bony structure of entire backbone, then protrudes into metal clip in opening, and be clipped in ridge it is prominent on, to reach
To the purpose of fixed tracer ontology, the pain and Infection probability of patient are increased in this way, and the shape that ridge is dashed forward is irregular
, it is unstable that metal clip is clipped in the prominent upper fixation of ridge, it is easy to positional shift occurs, in addition, metal clip is metal material, cost compared with
Height, processing technology are complicated；And metal clip can generate development when carrying out x-ray fluoroscopy, impact to the bone development of patient,
Artifact can be also generated, transparent effect is influenced.
Utility model content
To solve the above-mentioned problems, the utility model devises a kind of noninvasive fixation for spinal operation navigation tracer
Device, the fixation device and backbone fixation, will not move, and ensure that the navigation accuracy in operation.
In order to reach above-mentioned technical purpose, above-mentioned technical effect is realized, the utility model is real by the following technical programs
Existing:
A kind of noninvasive fixed device for spinal operation navigation tracer, including fixed block and positioning fixed pin, positioning
The quantity of fixed pin is at least 4, is evenly distributed on the two sides of fixed block；It is characterized by:
The fixed block is square block, and bottom surface opens up semicolumn groove, opens up cross recess among top surface, described ten
Word groove extends to fixed block edge and fixed block top surface is equally divided into four pieces, fixed block top surface and semi-cylindrical recesses axis phase
Parallel rib be removed formed be in plane 45 degree angles inclined-plane, uniformly open up at least four threaded hole on inclined-plane, threaded hole with it is oblique
Face is perpendicular to be connected to semicolumn groove；It designs screw thread in the positioning fixed pin to be placed in threaded hole, tail portion is fixedly connected
There is socket cap, periphery designs anti-skid chequer.
Further, the fixed block is PETG plastic material.
Further, the depth of the cross recess is 1-2cm.
Further, the diameter of the positioning fixed pin is 2mm.
The beneficial effects of the utility model are: the semicolumn groove of the utility model floor design can make fixed block be placed in ridge
The two sides of column make fixed block position fixing-stable, at the same position fixed pin by screw thread directly from skin surface screw in it is intraspinal,
It avoids the body surface in patient to open up wound and cause to infect, and positions fixed pin and be provided with more and be fixed on backbone difference
Position, and be fixed on the two sides of backbone, the pulling force to backbone is that balance can make to fix to reduce the damage to backbone
It is stronger.
Detailed description of the invention
In order to illustrate more clearly of the technical solution of the utility model embodiment, make required for being described below to embodiment
Attached drawing is briefly described, it should be apparent that, the drawings in the following description are merely some embodiments of the present invention,
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings
Other attached drawings.
