The utility model discloses use pubic tubercle place plane and closely laminate with pubic tubercle as reference point, guide die board, can pinpoint the incoming position and the angle of pulling force screw in the 12 inboard marrows of reverse superior ramus of pubis to the reduction is gone through the doctor and is required and think the factor error, and reduces the transmission number of times, reduces operation time, reduces operation complication, and help superior ramus of pubis well reset.
Description
Technical field
The utility model relates to medicine equipment, specifically refers to lag screw guiding in 1/2 marrow of a kind of reverse superior ramus of pubis inner sideTemplate.
Background technology
In superior ramus of pubis fracture, the rear main factor of impact fracture is the situation of the reduction of the fracture. Therefore, pubis arm boneThe reset of folded block and stable fixing most important, it is related to, and superior ramus of pubis sclerite is effectively fixing to be encircled before stablizing pelvis.Clinically middlely utilize lag screw in reverse superior ramus of pubis marrow that strong gripping point is provided, the good and Wicresoft of stability maintenance, hasHelp the good reset of superior ramus of pubis fracture, can avoid again open operation to cause and extensively peel off the shadow that image superior ramus of pubis blood is transportedThe generation of loud and corresponding artificial Iatrogenic Complications.
Reverse superior ramus of pubis screw is fixing becomes conventional superior ramus of pubis fracture because it has good biomechanical propertyOne of internal fixation method. At present, for the location of lag screw in the 1/2 fracture marrow of reverse superior ramus of pubis inner side substantially allBe to carry out touch system according to radioscopy result in art, affected by C type arm perspective in art, and relevant with patient's experience.Complicated important because of pelvis adjacent structure, what nail was put in operation requires highly, and difficulty is large. If the implantation position of screw is not good, meetingCause pelvic nerve, injury of blood vessel, even threat to life. The main points of operation are that pedicle screw must pass through narrow and small boneProperty passage. But due to the difference in individual superior ramus of pubis anatomy, only determine with operative doctor experience, so just can not keep awayCan produce the error of human factor with exempting from, and in art, need a large amount of perspectives, cause lag screw in superior ramus of pubis marrow to be located notSatisfied, thus operating time extended, and relevant postoperative complication happens occasionally, and when serious, can cause operative failure.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of can accurately lead contrary for the present situation of prior artTo lag screw guiding die plate in 1/2 marrow of superior ramus of pubis inner side, thereby reduce, doctor's experience is required and transmission number of times.
The utility model solves the problems of the technologies described above adopted technical scheme: in this reverse superior ramus of pubis inner side 1/2 marrowLag screw guiding die plate, is characterized in that comprising for being fitted in the location-plate on pubis lateral surface, described location-plateOn binding face, have the round and smooth convex surface suitable with pubis lateral surface structure, location-plate is provided with at least three locating holes, fixedThe middle part of position plate is provided with pilot hole, is connected with guide pipe, on the axis of described guide pipe and Ipsilateral pubis on described pilot holeInside, the central passage of 1/2 fracture is suitable.
Preferably, described location-plate can adopt and have flexible medical material preparation;
The axis of described guide pipe becomes 41.5～47.5 ° of angles with respect to the sagittal plane of described location-plate thickness direction, relativelyCross section in described location-plate becomes 46.5～52.5 ° of angles. This structure can be by the distortion of the location-plate Different Individual of coincideingPubis structure, the angle that the distortion by location-plate simultaneously can corresponding adjustment guide pipe, can adaptive different othernessesIndividuality.
In such scheme, the thickness≤1mm of preferred described guide plate, the internal orifice dimension of described guide pipe and described pilot holeFor 4mm, the length of described guide pipe is 5～7mm, and the aperture of described locating hole is 1～2mm.
Preferably, described locating hole has four, and each described locating hole lays respectively on the edge angle of described location-plate.
Compared with prior art, lag screw guiding module in 1/2 marrow of reverse superior ramus of pubis provided by the utility model inner sidePlate is taking tuberculum pubicum place plane as reference point, and guiding die plate and tuberculum pubicum fit tightly, and can accurately locate reverse shameIncoming position and the angle of lag screw in 1/2 marrow of inner side on bone, require and think factor doctor's experience thereby reduceError, and reduce transmission number of times, reduce operating time, reduce postoperative complication, help superior ramus of pubis well to reset.
Brief description of the drawings

Fig. 3 is that the utility model embodiment uses view.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1 to Figure 3, in this reverse superior ramus of pubis inner side 1/2 marrow, lag screw guiding die plate comprises:
Location-plate 1, for being fitted in pubis lateral surface, is the pedestal of whole guiding die plate; Location in the present embodimentPlate 1 adopts has flexible medical plastic preparation, and its thickness is 1mm; Location-plate 1 medial surface with the subsides of pubis 3Close on face, have with pubis lateral surface on the suitable round and smooth convex surface 11 of recess, each on the position at four angles of location-plate 1Be provided with a locating hole 12, the aperture of locating hole 12 is 1mm, with the Kirschner wire of 1.0mm easy to use (in figure notIllustrate).
The middle part of location-plate is provided with pilot hole 13, is connected with guide pipe 2 on pilot hole 13, pilot hole 13 and guide pipe 2Dead in line, and both internal diameters equate. Pilot hole 13 can be one-body molded with guide pipe 2, also can be for dividingBody structure.
Guide pipe 2, leads to lag screw 4, can accurately enter central passage inside superior ramus of pubis. LeadAxis to pipe becomes 41.5～47.5 ° of angles with respect to the sagittal plane of location-plate 1 thickness direction, tilts to pubis outside41.5～47.5 °, the present embodiment is 45.5 °; The axis of guide pipe also becomes with respect to the cross section of location-plate simultaneously46.5～52.5 °, tilt 46.5～52.5 ° to pubis top, the present embodiment is 50.1 °.
The internal orifice dimension of pilot hole and guide pipe is 4mm, and the length of guide pipe 2 is 6mm.
In clinical use, after the reduction of the fracture of Ipsilateral superior ramus of pubis is satisfied, appear patient's tuberculum pubicum, just location-plate is protrudingFace is fitted in the concave surface of pubis lateral surface, squeezes into respectively the Kirschner wire of 1.0mm, by location-plate in four locating holesBe fixed on pubis side, now, the axis of guide pipe overlaps with the central passage of Ipsilateral superior ramus of pubis inner side 1/2 marrow;Select the os integumentale screw of diameter 7.0mm hollow, reverse superior ramus of pubis inner side 1/2 bone of squeezing under the guiding of guide pipeIn passage. Effectively avoid lag screw in the 1/2 fracture marrow of reverse superior ramus of pubis inner side to pass the problem of cortex of bone, greatlyImprove success rate of operation.
