Abstract
A kind of angle adjustable neck of femur blade plate, belongs to technical field of medical instruments.Comprise femur fracture plate, lag screw sleeve, the hub internal bore of lag screw sleeve, the boss of lag screw sleeve bottom, the axle bed of the boss of lag screw sleeve bottom is installed in the active cooperation of femur fracture plate upper end, it is characterized in that: boss and axle bed are respectively arranged with the identical boss ratchet hole of structure and axle bed ratchet hole, one engages the T-shaped ratchet shaft mated moves to coordinate by the boss of lag screw sleeve bottom be assemblied on the axle bed of femur fracture plate with boss ratchet hole and axle bed ratchet hole, the other end of T-shaped ratchet shaft is provided with inner bolt hole or external screw thread, one can make axle bed horizontal pressurized the inner bolt hole of stuck for boss tommyhead bolt in axle bed or nut and T-shaped ratchet shaft or external screw thread be matched.This utility model it not only can make between lag screw sleeve and femur fracture plate angle scalable, and structure is simple, and volume is little, lightweight, and cost is low, and angle adjustment operation is convenient and swift, thus can bring convenience for surgical.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of angle adjustable neck of femur blade plate.
Background technology
Intertrochanteric fracture of the femur, intertrochanteric fracture of the femur and fracture of femoral neck etc. are common cases in fracture, adopt neck of femur blade plate to be treatment intertrochanteric fracture of the femur, one of intertrochanteric fracture of the femur and fracture of femoral neck common method clinically.Be mostly the nonadjustable product of angle on the market at present, mainly contain the neck of femur blade plate that angle is 95 °, 130 ° and 135 °, therefore, before clinical operation, doctor can only select and the immediate steel plate of patient femur's profile angle.The neck of femur blade plate of adjustable angle is there has been proposed, as notification number: CN 2852972 " angle changeable type DHS femoral fixator ", publication number: CN1420747, technical schemes such as " devices of rotational stabilization of bone segments " for above-mentioned disadvantage.But the former technical scheme is led to worm screw and is engaged the angle regulating bone screw and femur fixing head with sector rack, and worm screw and sector rack not only cost is high, and volume is large, Heavy Weight.The technical scheme of the latter comprises a blade plate, a bone lag screw (18) and a retainer (24).What this technical scheme blade plate can only make radial angle relative to bone lag screw (18) rotates adjustment, and can not do the adjustment of axial angle.
Summary of the invention
This utility model object is the disadvantage existed to overcome above-mentioned prior art, a kind of angle adjustable neck of femur blade plate is provided, it not only can make the angle scalable between lag screw sleeve and femur fracture plate, and structure is simple, volume is little, lightweight, cost is low, angle adjustment operation is convenient and swift, thus can bring convenience for surgical, shortens operating time.
Above-mentioned goal of the invention is achieved through the following technical solutions: a kind of angle adjustable neck of femur blade plate, comprise femur fracture plate, lag screw sleeve, the hub internal bore of lag screw sleeve, the boss of lag screw sleeve bottom, the axle bed of the boss of lag screw sleeve bottom is installed in the active cooperation of femur fracture plate upper end, its main points are: boss and axle bed are respectively arranged with the identical boss ratchet hole of structure and axle bed ratchet hole, one engages with boss ratchet hole and axle bed ratchet hole the T-shaped ratchet shaft mated passes axle bed ratchet hole, the boss of lag screw sleeve bottom moves to coordinate and is assemblied on the axle bed of femur fracture plate by boss ratchet hole, thus make the angle scalable between lag screw sleeve and femur fracture plate, the other end of T-shaped ratchet shaft is provided with inner bolt hole or external screw thread, one can make axle bed horizontal pressurized the inner bolt hole of stuck for boss tommyhead bolt in axle bed or nut and T-shaped ratchet shaft or external screw thread be matched.
As preferably, the axle bed of femur fracture plate and the boss of lag screw sleeve are provided with the angle index indicatrix representing femur fracture plate relative tension screw sleeve adjusting angle.
As preferably, lag screw sleeve and femur fracture plate angle range of accommodation are 90 ° ~ 140 °.
As preferably, the ratchet of boss ratchet hole, axle bed ratchet hole, T-shaped ratchet shaft is divided into 36 or 72 equably, and lag screw sleeve and femur fracture plate angle minimal adjustment unit are 10 ° or 5 °.
This utility model beneficial effect compared with prior art: it to engage by one the T-shaped ratchet shaft mated and regulates angle between lag screw sleeve and femur fracture plate with boss ratchet hole and axle bed ratchet hole, so structure is simple, body is little, lightweight, cost is low, angle adjustment operation is convenient and swift, thus can bring convenience for surgical, shortens operating time.

Detailed description of the invention
Just represented by Fig. 1-4, embodiment is further described this utility model below: comprise femur fracture plate 1, lag screw sleeve 2, the hub internal bore 3 of lag screw sleeve 2, the boss 4 of lag screw sleeve 2 bottom, the axle bed 5 of the boss 4 of lag screw sleeve 2 bottom is installed in the active cooperation of femur fracture plate 1 upper end, boss 4 and axle bed 5 are respectively arranged with the identical boss ratchet hole 6 of structure and axle bed ratchet hole 7, one engages with boss ratchet hole 6 and axle bed ratchet hole 7 the T-shaped ratchet shaft 8 mated passes axle bed ratchet hole 7, boss 5 dynamic cooperation of lag screw sleeve 2 bottom is assemblied on the axle bed 5 of femur fracture plate 1 by boss ratchet hole 6, thus make the angle scalable between lag screw sleeve 2 and femur fracture plate 1, the other end of T-shaped ratchet shaft 8 is provided with inner bolt hole 9, and one can make axle bed 5 horizontal pressurized be matched with the inner bolt hole 9 of T-shaped ratchet shaft 8 by stuck for boss 4 tommyhead bolt 10 in axle bed 5, the axle bed 5 of femur fracture plate 1 and the boss 4 of lag screw sleeve 2 are provided with and represent that the angular range of femur fracture plate 1 relative tension screw sleeve 2 adjusting angle is the graduation indication line 11 of 95 ° ~ 135 °.The ratchet of boss ratchet hole 6, axle bed ratchet hole 7, T-shaped ratchet shaft 8 is divided into 72 equably, and lag screw sleeve 2 and femur fracture plate 1 angle minimal adjustment unit are 5 °.
