Abstract
The utility model discloses a radian measuring instrument for the connecting rod of a screw-rod system in the orthopedics department and belongs to the technical field of medical apparatus and instruments. The radian measuring instrument comprises a measuring plate, the lower right corner of the measuring plate serves as a peak, the bottom edge of the measuring plate serves as a zero graduation line, a plurality of angle measuring lines are arranged on the measuring plate, and a plurality of concentric arcs taking the peak as a center are further arranged on the measuring plate; the radian measuring instrument provided by the utility model has a simple structure, is reasonable in design, convenient to use, do not require medical staff to judge according to experiences, reduces errors, avoids repeated rod folding during operation, and can effectively prevent harmful complications after operation.
Description
Technical field
This utility model relates to technical field of medical instruments, nail-stick system pitman arc measurement instrument for especially a kind of orthopaedics.
Background technology
Operation for thoracolumbar fractures therapeutic purposes comprise recovers the height of vertebral body, the correction of the reset of bone fragments in vertebral canal, sagittal plane deformity finally reaches the reconstruction of spinal stability.The correction of sagittal plane deformity relies on the bending of nail-stick system titanium rod in art.But in operation process, due to the bending radian neither one standard value of titanium rod, the accurate radian of titanium rod relies on patient's experience to operate mostly.Inevitable like this causing in art repeatedly repeated curved rod, and postoperative check finds that fracture segment is larger or less at the radian of orthopedic rear sagittal plain, and then need to again perform the operation.
Summary of the invention
Technical assignment of the present utility model is the nail-stick system pitman arc measurement instrument for a kind of orthopaedics providing for above the deficiencies in the prior art.
This utility model solves the technical scheme that its technical problem adopts: nail-stick system pitman arc measurement instrument for a kind of orthopaedics, comprise measurement plate, the lower right corner of described measurement plate is summit, base is zero graduation line, be provided with some angular surveying lines measuring on plate, on described measurement plate, be also provided with some isocentric circular arc that summit is the center of circle of take.
The measuring range of described angular surveying line is 0 °-45 °.
The radius of described isocentric circular arc is 0-200mm.
On the right flank of described measurement plate and bottom surface, be respectively equipped with measurement baffle plate, be convenient to doctor and measure in operation.
The utility model has the advantage of: simple in structure, reasonable in design, easy to use, without medical worker, rule of thumb judge, reduced error, avoid folding rod, the effectively generation of the bad complication of prevention of postoperative repeatedly in art.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with Figure of description, this utility model is described below.
As shown in the figure, nail-stick system pitman arc measurement instrument for a kind of orthopaedics, comprises and measures plate 1, the lower right corner of described measurement plate 1 is summit 2, base is zero graduation line, is provided with some angular surveying lines 3 measuring on plate 1, is also provided with some isocentric circular arc 4 that summit is the center of circle of take on described measurement plate 1.
The measuring range of described angular surveying line 3 is 0 °-45 °.
The radius of described isocentric circular arc 4 is 0-200mm.
On the right flank of described measurement plate 1 and bottom surface, be respectively equipped with and measure baffle plate 5, be convenient to doctor and measure in operation.
The anatomical features of the sagittal plane physiological camber of the normal breast lumbar vertebra of this measuring instrument utilization, according to preoperative assessment or with reference to need fixed-segment ordinary people's Cobb angle be the bending angle of titanium rod in art.In art, titanium rod is curved to standard round arc as far as possible, one end of titanium rod is positioned over to 2 places, summit of this measuring instrument, the other end finds the angle corresponding with this titanium rod length in isocentric circular arc 4, measures efficient and convenient.
