Description
Technical field
This utility model relates to medical apparatus and instruments aid, refers specifically to outside a reverse superior ramus of pubis pulling force spiral shell in 1/2 marrow
Nail guiding die plate.
Background technology
Reverse superior ramus of pubis screw is fixing becomes what conventional superior ramus of pubis was fractured because it has good biomechanical property
One of internal fixation method.Outside reverse superior ramus of pubis, 1/2 because of next-door neighbour acetabular bone, pelvis medial wall, and operative site exists deeply, puts
The requirement of nail is high, and difficulty is big, and relevant postoperative complication happens occasionally.If the implantation position of screw is the best, hip can be caused
Mortar damages, femoral head damage and pelvic nerve, blood vessel injury and injury of bladder.It is necessary that operation is characterized by pedicle screw
By narrow and small bone passage.
In routine operation, outside reverse superior ramus of pubis, in 1/2 marrow, lag screw is inserted and is fixed and relies primarily on X-ray in art
Pivoting results determines outside reverse superior ramus of pubis the position of lag screw in 1/2 marrow, then carries out touch system, by C in art
Arm pivoting results and the experience of operative doctor and the impact of technology, and owing to anatomical position is relatively deep, art is difficult to accurately
Location, inevitably results from the error of anthropic factor, causes screw to deviate, and lag screw fixed position is not satisfied,
Cause damage and acetabular bone, the capital damage of pelvic blood vessels, time serious, may result in operative failure；And art needs big
Amount perspective, has certain damage to human body.
Summary of the invention
Technical problem to be solved in the utility model is that the present situation for prior art provides one can thoroughly avoid people
For factor impact, help operative doctor to carry out outside the reverse superior ramus of pubis that is accurately positioned lag screw in 1/2 marrow to guide
Template, thus reduce perspective number of times, ensure to improve success rate of operation, avoid the generation of artificial Iatrogenic Complications.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is: outside this reverse superior ramus of pubis in 1/2 marrow
Lag screw guiding die plate, it is characterised in that include and location-plate and lead；
Described location-plate include with described superior ramus of pubis outside the suitable outer panel top suitable with superior ramus of pubis end face
Plate and with superior ramus of pubis inside suitable interior plate, described outer panel, top board and interior plate are one-body molded；Described outside
On plate, the location interval near lower limb is provided with hole, two location, and the middle part of described outer panel is provided with pilot hole；
Described lead is the tubular structure of hollow, and a port of lead connects described pilot hole；Described pilot hole
Axis is 38～42 ° relative to the sagittal plane angle of described outer panel, and the axis of described pilot hole is relative to described outer panel
Coronalplane angle be 43～47 °.
Described interior plate connects 0.25-0.4 times of the edge length of a length of described top board at the edge of described top board, and
The deployed condition of described interior plate be angle, outer end be the triangular structure of fillet.
The thickness of described location-plate is 0.9-1.2mm, and the aperture in hole, described location is 0.9-1.1mm, described pilot hole
Aperture is 2.8-3.2mm, a length of 5-7mm of described pilot hole.4
The guiding die plate of multiple specification can be prepared, with the crowd of adaptive different building shape in the range of above-mentioned each scheme.
Compared with prior art, lag screw guiding module in 1/2 marrow outside reverse superior ramus of pubis provided by the utility model
Plate designs according to CT Three-dimensional anatomical evaluation statistical data, and outside Ipsilateral pubic tubercle, place plane is as reference point, guides
Template fits tightly with Ipsilateral pubic tubercle place plane, is inserted outside reverse superior ramus of pubis by the guide channel of hollow
Lag screw in 1/2 marrow, can accomplish to put nail accurate, it is to avoid pulling force in 1/2 fracture marrow outside reverse superior ramus of pubis
Screw passes the problem of cortical bone, effectively reduces operating time and perspective number of times, and minimizing fluoroscopy during operation, to human injury, subtracts
The generation of the artificial Iatrogenic Complications that lag screw position deviation causes in 1/2 marrow outside few reverse superior ramus of pubis, and knot
Structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As it is shown in figure 1, in 1/2 marrow, lag screw guiding die plate includes outside this reverse superior ramus of pubis:
Location-plate 1, thickness is 1 millimeter, uses medical grade resin to be prepared from；Fit including outside superior ramus of pubis
The top board 12 that fits with superior ramus of pubis end face of outer panel 11 and with superior ramus of pubis inside the interior plate 13 that fits,
Outer panel 11, top board 12 and interior plate 13 are one-body molded；It is spaced on two side positions of outer panel 11 lower limb and sets
Having hole 14, two location, the middle part of outer panel 11 is provided with pilot hole 15；Described interior plate 13 connects described top board 12
