Abstract
The utility model relates to a medical utensil, particularly a vertebral arch pedicle screw positioner used in a bone surgery. The utility model has the technical scheme that the position between two sleeve pipes is hinged with a telescopic transverse rod through a fixed block to form an H-shaped support frame, and by fixing a small sleeve pipe in the vertical direction at the middle part of the transverse rod, an inner sleeve of the small sleeve pipe is provided with a spinous process fixing needle. The inner sleeves of two sleeve pipes are provided with tapping cones. Two ends of the transverse rod is inwards and respectively provided with graduated scales, and the graduated scales are respectively and orderly arranged on the tapping cone and the fixing needle along the tip upwards. The fixed block comprises a sleeve hoop and a screw bolt. The utility model has the effect that after a doctor can calculate the position, the angle and depth of needed fixed steel nails according to an X-ray sheet of a patient, by adjusting the position, the angle and the depth of an associated component of the utensil, the utensil is positioned on the operated position of the patient. Through the auxiliary positioning action of the utensil, needed screw holes are accurately drilled. The utensil has the advantages of simple structure, convenient operation and accurate positioning.
Description
One, technical field:
This utility model relates to a kind of medical apparatus, is the pedicle screw localizer that uses in a kind of bone surgery specifically.
Two, background technology:
At present in the pedicle of vertebral arch that Orthopeadic Surgery carries out is drilled the process of screw hole fully by manual operation, lack necessary location utensil, departing from or locate the situation of being forbidden often appears in the screw hole of drilling like this, has brought misery to the patient, has influenced fixed effect simultaneously.
Three, summary of the invention:
The purpose of this utility model is exactly the problem that exists at complete manual operations, and a kind of pedicle screw localizer is provided.
Its technical scheme is: form " H " shape support by the fixed block hinge by telescopic cross bar between two sleeve pipes, by being fixed with small casing, be with the spinous process locking pin in the middle part of cross bar vertical direction in small casing, be with the tapping awl in two sleeve pipes.Be respectively equipped with rule in the cross bar inward at both ends, on tapping awl and locking pin, be provided with rule successively along point upward respectively.Described fixed block comprises cuff and bolt composition.
To be the doctor can calculate needs fixedly behind the position, angle, the degree of depth of steel nail according to patient's X-ray sheet to effect of the present utility model, position, angle and the degree of depth of the associated components by adjusting utensil, utensil is placed in the position of needs of patients operation, by the assist location effect of utensil, the screw hole of accurately drilling and needing.This utensil structure is simple, and is easy to operate, and accurate positioning has good application prospects.
Four, description of drawings:
Accompanying drawing is a perspective view of the present utility model.
Five, specific embodiment:
With reference to accompanying drawing, between two sleeve pipes 2, form " H " shape support by telescopic cross bar by cuff 3 and bolt 4 hinges.Cross bar is pegged graft to cooperate by trocar sheath 6 and inner sleeve 9 and is formed, and can adjust width and angle between such two sleeve pipes 2 and the cross bar.Be fixed with small casing 8 in the middle part of cross bar vertical direction by cuff 3 and bolt 4, in small casing, be with spinous process locking pin 7.In two sleeve pipes 2, be with tapping awl 1.For the ease of observing and calculating, on two sleeve pipes 2, be provided with rule 5 from bottom to top, be respectively equipped with rule 5 in the cross bar inward at both ends, on tapping awl and locking pin, be provided with rule 5 successively along point upward respectively.
Claims (3)
1, a kind of pedicle screw localizer, it is characterized in that: between two sleeve pipes, form " H " shape support by telescopic cross bar by the fixed block hinge, by being fixed with small casing, in small casing, be with the spinous process locking pin in the middle part of cross bar vertical direction, in two sleeve pipes, be with the tapping awl.
2, pedicle screw localizer according to claim 1 is characterized in that: be respectively equipped with rule in the cross bar inward at both ends, be provided with rule successively along point upward respectively on tapping awl and locking pin.
