Description
Technical field
The present invention relates to a kind of bone surgery utensil, a kind of auxiliary acetabular anterior column direct motion screw merging and when fracturing removing
The surgical instrument that positioning is conveniently fixedly connected can be aimed at immediately.
Background technique
The fixed operation wound of acetabular anterior column screw is small, fixed reliable, influences on surrounding tissue small, is a kind of excellent interior solid
Determine mode.But since anatomical tissue important around acetabular anterior column is more, screw placement difficulty is big, after slightly deviation may cause seriously
Fruit, clinically often using screw placement mode of driving in the wrong direction, lower implantation is looked on the road Ji Qian straight after cutting；It results in needing front and back road in this way
The patient of operation, needs to change in art position and the sterile list of disinfection paving could be completed entirely to perform the operation again, leads to operating time
Extend, increases the possibility that operation surprisingly occurs.Technology is placed in using acetabular anterior column direct motion screw at this time, then patient uses one
Entire operation can be completed in position；But due to the relationship of anatomical structure, acetabular anterior column direct motion screw merging technology is difficult to using hand
The mode of art direct-view, when merging, is more difficult, and application clinically is greatly limited.
Also due to anatomy relationship, clinically when carrying out fracture of acetabulum posterior approach, quilt in front of greater sciatic notch plane
It is considered as operation forbidden zone, does not allow to carry out in this region the operation such as to remove.Inventor passes through the anatomical structure hair studied in detail herein
A degree of removing now is carried out to this region and the operations such as the reduction of the fracture be it is safe, this point is further in later reality
It is verified in surgical procedure.Inventor invents the sighting device, and operator can greatly be facilitated to pass through acetabular bone posterior approach
Direct motion is placed in acetabular bone anterior screw.
In addition, first having to the nerve, blood vessel, bone to fracture site when being attached fixation for treatment operation to fracture site
The hard and soft tissues such as film carry out cleaning removing with removing spoon, and detect preferable point in cleaning removing and be attached fixation.?
During this, usually after the completion of clearing up removing, removing utensil is transferred to, suitable point is then found again and is attached admittedly
It is fixed, but transfer to remove spoon after because losing object of reference, doctor is with sight and feels to operate, to the point of operative approach with
Angle is difficult to accurately differentiate, be connected and fixed and exchange internode away from and angle all determined by the experience of doctor, be easy to produce people
For error.
CN2582553Y proposes a kind of bone surgery sighting device, aims at for cone positioning and directing, by workbench and leads
It is formed to device, structure is more complicated, is only used in centrum artis, and need having according to spiral CT three-dimensional rebuilding in the preoperative
Data are closed to support.Therefore most of human body fractures are not determined accurately and reliably there are in the poor situation of medical condition
Position object of reference, or feel to operate with medical experience by the sight of doctor, it be easy to cause human error and accident.
Summary of the invention
The present invention is placed in the difficult point of acetabular bone anterior screw for current acetabular bone posterior approach direct motion, and fracture is connected and fixed
Operative treatment, which exists, lacks positioning datum point, still feels the defect operated with medical experience, design with the sight of doctor
A kind of band aims at the stripper of positioning, when doctor carries out removing cleaning to fracture site, is determined by subject matter of stripper
Position is aimed at, and is carried out fracture site immediately and is aimed at the fixation that is located by connecting, and fracture fixation connection operation is completed.
The technical solution of the invention is as follows:
Fracture removing aims at locator, including stripper and guider, it is characterized in that the stripper by stripping rod, be located at removing
The removing spoon that bar front end extends is located at the handle composition of removing rod rear end, and the stripping rod upper end connects a cross bar guider, institute
It states and is longitudinally uniformly arranged several pilot holes in cross bar guider, guide cylinder, socket in the guide cylinder are socketed in the pilot hole
The guide pin of alignment removing spoon blade endpoint.
Described removing spoon one end is detachably fixed with stripping rod to be connect, and the other end is hilted broadsword sword or double cutting edge ellipse arc cutter
Piece.
The cross bar guider is circular arc camber bar, and top and bottom are to remove spoon blade endpoint as the circular arc camber in the center of circle.
The guide cylinder is made of clamping head and folder needle tubing, and folder needle tubing is first inserted in pilot hole, and clamping head presss from both sides guide pin
Hold fastening.
The radian of the circular arc camber is 45~50 degree of circular arc curvatures centered on exploiting spoon blade.
Spacing is 7~8 degree of circular arc curvatures between pilot hole in the cross bar guider.
The stripper of the present apparatus removes irregular bone folding face with the removing spoon front end edge of a knife, and the articular surface of removing has blood vessel, mind
Through, periosteum, tendon etc., with stripper Detection location to optimal point while removing, immediately on cross bar guider
Pilot hole alignment removing spoon where point, select suitable pilot hole socket upper bush and be inserted in fixing glue.Utilize removing spoon
It is accurately positioned for benchmark target, the appropriate location reference point of target may be selected, fracture is made to be connected and fixed facilitating operation peace
Entirely, reach quick minimally invasive effect, be particularly suitable for the need of the disaster relief or wartime first aid.
Detailed description of the invention
Fig. 1 is schematic diagram of the three-dimensional structure.
Fig. 2 is Fig. 1 vertical section structure schematic diagram.
Fig. 3 is that pilot hole socket aims at schematic diagram.
Fig. 4 is embodiment schematic diagram.
Specific embodiment
Referring to shown in Fig. 1, fracture removing sighting device includes stripper and guider, and the stripper is located at by stripping rod 1
The removing spoon 2 and be located at the composition of handle 3 for removing rod rear end that 1 front end of stripping rod extends, 1 upper end of stripping rod connects a cross bar
Guider 4 is longitudinally uniformly arranged several pilot holes 5 in the cross bar guider, and described 2 one end of removing spoon and stripping rod are detachable
It is fixedly connected, the other end is the elliptic arc blade of hilted broadsword sword or double cutting edge.Stripping rod 1 is mutually perpendicular to be fixed for pushing away with handle 3
Dynamic or rotation operation removing spoon 3.
Referring to shown in Fig. 2, Fig. 3, cross bar guider 4 is circular arc camber bar, and above and below is to remove spoon blade endpoint 8
For the circular arc camber in the center of circle.The radian of the circular arc camber is 45~50 writing music face centered on removing spoon blade endpoint,
The cross bar guider 4 is longitudinal to be uniformly arranged pilot hole 5, and the spacing between pilot hole 5 is 7~8 circular arc degrees.In the pilot hole
It is socketed guide cylinder 6 in 5, guide pin 7 is socketed in the guide cylinder 6, if guide pin 7 is to remove 2 blade of spoon as aiming point, from cross
In many pilot holes 5 of rod guide 4, the 5 pairs of 2 blade end points of removing spoon of pilot hole for selecting position proper are taken aim at one by one
Standard selects appropriate point to squeeze into fracture fixing apparatus, carries out minimally invasive fixed surgical procedure of fracturing, to improve operation accuracy rate.
Removing spoon cutting edge can be known common knife-edge, can also need to design more applicable knife-edge according to clinical,
To adapt to a variety of positions and bone types.
The guide cylinder is made of clamping head 61 and folder needle tubing 62, and folder needle tubing 62 is first inserted in pilot hole 5, and clamping head 61 will
