Abstract
The utility model discloses a calibrator for operation navigation system comprises steel needle and hood, and the cantilever is held to metal steel needle needle point, and another end is vertical quadrangular, the circular piece of plastics hood for having thickness, one side have around screw form slot, and there is an arch of taking the quadrangular shape recess at the center of another side, insert the end cooperation of steel needle quadrangular on the hood in the bellied quadrangular shape recess, constitute a calibrator for operation navigation system. The utility model discloses simple structure, convenient to use can discover in the art and ration navigation deviation to guide going on smoothly of operation.
Description
Art
This utility model relates to technical field of medical instruments, particularly relates to a kind of aligner for operation guiding system.
Background technology
Recently as scientific and technological progress, modern operation guiding system has been applied in hospital clinical operation, operation guiding system, be by image data in preoperative for patient or art and on operation table differences in patient accurately corresponding, operation is followed the tracks of operating theater instruments and the position of operating theater instruments form real-time update with virtual probe on patient's image is shown, make doctor that operating theater instruments is very clear relative to the position of differences in patient, make surgical operation more rapid, more accurate, safer. But in clinical manipulation, it is likely to occur various error, causes the deviation of navigation final effect, affect surgical effect. Presently used operation guiding system all lacks deviation calibration device, the deviation found can not be carried out quantitative adjusting, have influence on the degree of accuracy of surgical navigational. If this deviation can be found in art in time and how much carries out quantitative deviation, then it is more beneficial for being successfully completed of navigating surgery. Develop and a kind of can find navigation deviation in art in time and to carry out the quantitative aligner for operation guiding system be the task that the art has needed.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of simple in construction, easy to use, can find in art and the aligner being used for operation guiding system of deviation of quantitatively navigating, in order to being smoothed out of guided operation.
In order to achieve the above object, this utility model adopts following structural principle: a kind of aligner for operation guiding system, is made up of draw point and top cap, is characterized in: metal draw point needle tip cantilever, and other end termination is longitudinal quadrangular; Plastics top cap is the circular piece with thickness, top cap one side is with around screw-like channels, the center of top cap another side is provided with the projection of four prism type groove, four prism type groove is corresponding with the quadrangular of draw point termination, draw point quadrangular termination is coordinated in the four prism type groove inserting top cap projection, constitute the aligner for operation guiding system.
In described top cap, the spacing around screw-like channels is 1 millimeter.
When this utility model uses, before navigation starts, metal draw point needle tip is squeezed in the bone around operating space by electric drill, insert in the four prism type groove of top cap one side at draw point quadrangular end; During navigation, metal draw point is scanned into the visual field; During operation, detector nib (pointer) is directed at the top cap center around screw-like channels, and compares in navigation picture, with accuracy of judgement degree;If there is deviation, detector nib (pointer) is moved between top cap screw thread, after monitor shows that detector nib is corresponding with center, the distance at record actual detector nib distance top cap center and direction, it is the degree of deviation, thus quantitatively inclined extent, it is simple to adjust deviation, it is ensured that smoothly completing of operation.
This utility model simple in construction, easy to use, can find in art and quantitatively navigate deviation, in order to being smoothed out of guided operation, has reached goal of the invention.
