Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to the little tuberosity fracture reduction fixator of a kind of femur.
Background technology
Intertrochanteric fracture of the femur is the common fracture of Orthopedic Clinical, most intertrochanteric fracture of the femur are associated with little tuberosity fracture simultaneously, special anatomical position (at the interior rear of femur) due to the little tuberosity of femur, in art, cannot look at straight and appear sclerite, opereating specification limitation, common fracture fixing apparatus cannot use, so fix for the reset of little tuberosity, is a bone surgery difficult problem always, previously common way is not give operation to fix or fix reluctantly, and often position is not good enough.
Summary of the invention
The object of this invention is to provide the little tuberosity fracture reduction fixator of femur that a kind of result of use is good.
For achieving the above object, the technical solution used in the present invention is:
The little tuberosity fracture reduction fixator of a kind of femur, comprise fixed mount and adjustable shelf, fixed mount is " ［ " shape, adjustable shelf is " L " shape, fixed mount comprises vertical portion, vertical portion vertically arranges, vertical portion upper end is fixedly connected with transverse part, transverse part horizontally set, vertical subordinate's end is fixedly connected with hook portion, adjustable shelf comprises threaded rod, threaded rod vertically arranges, threaded rod lower end is fixedly connected with removable cross bar, removable cross bar horizontally set, it is characterized in that: on transverse part, have threaded rod perforation, threaded rod passes in threaded rod perforation, swing handle has been threaded on threaded rod, swing handle is relative with transverse part to be rotatably connected, removable cross bar outer end has guide pipe perforation, in guide pipe perforation, be fixedly connected with positioning and guiding pipe, positioning and guiding tube hub is corresponding up and down with hook portion outer end.
According to the little tuberosity fracture reduction fixator of described femur, it is characterized in that: described removable cross bar inner end is fixedly connected with sliding sleeve, and sliding sleeve slides up and down and is connected with the vertical portion of described fixed mount.
According to the little tuberosity fracture reduction fixator of described femur, it is characterized in that: the vertical portion cross section of described fixed mount is polygon.
According to the little tuberosity fracture reduction fixator of described femur, it is characterized in that: described positioning and guiding pipe lower end is zigzag.
According to the little tuberosity fracture reduction fixator of described femur, it is characterized in that: in the middle of described hook portion, be bent downwardly, hook portion outer end is most advanced and sophisticated.
For addressing the above problem, the applicant, in long-term operation practice, to dissecting on the basis of abundant research, has invented this special equipment.In art, its hook portion tip can be walked around femur, be hooked the little tuberosity of femur center, indentation position, positioning and guiding pipe lower end is stuck in lateral side of femur face, by swing handle, make to produce pressurization between hook portion tip and two contact points of positioning and guiding pipe sawtooth end, thereby make the reset of pressurizeing completely of little tuberosity sclerite; One end of removable cross bar can be stable by sliding sleeve in the vertical portion of adjustable shelf, with the movement of removable cross bar, move, positioning and guiding Guan center is corresponding up and down with the hook portion bill of fixed mount, by positioning and guiding pipe bit hole, just can be drilled in the centre of little tuberosity sclerite, direction can obtain Reliable guarantee, this apparatus can guarantee to reset and once be successfully completed with fixing, flexible operation is easy, has fundamentally solved the fixing difficult problem of the little tuberosity reduction of the fracture of femur, and result of use is good.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
The little tuberosity fracture reduction fixator of a kind of femur, as shown in Figure 1, comprise fixed mount 3 and adjustable shelf 1, fixed mount 3 is " ［ " shape, adjustable shelf 1 is " L " shape, fixed mount 3 comprises vertical portion 32, vertical portion 32 vertically arranges, vertical portion 32 upper ends are fixedly connected with transverse part 31, transverse part 31 horizontally sets, vertical portion 32 lower ends are fixedly connected with hook portion 33, adjustable shelf 1 comprises threaded rod 11, threaded rod 11 vertically arranges, threaded rod 11 lower ends are fixedly connected with removable cross bar 12, removable cross bar 12 horizontally sets, it is characterized in that: on transverse part 31, have threaded rod perforation, threaded rod 11 passes in threaded rod perforation, swing handle 2 has been threaded on threaded rod 11, swing handle 2 is relative with transverse part 31 to be rotatably connected, removable cross bar 12 outer ends have guide pipe perforation, in guide pipe perforation, be fixedly connected with positioning and guiding pipe 4, positioning and guiding pipe 4 centers are corresponding up and down with hook portion 33 outer ends.
In the present embodiment, described removable cross bar 12 inner ends are fixedly connected with sliding sleeve 13, and sliding sleeve 13 slides up and down and is connected with the vertical portion 32 of described fixed mount 3.Vertical portion 32 cross sections of described fixed mount 3 are polygon.Described positioning and guiding pipe 4 lower ends are zigzag.In the middle of described hook portion 33, be bent downwardly, hook portion 33 outer ends are most advanced and sophisticated.
Embodiment recited above is described the preferred embodiment of the present invention; not the spirit and scope of the present invention are limited; do not departing under the prerequisite of design concept of the present invention; various modification and improvement that in this area, common engineers and technicians make technical scheme of the present invention; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection, is all documented in claims.
The present invention is made by medical stainless steel material, comprises fixed mount, adjustable shelf, positioning and guiding pipe and swing handle, and fixed mount is divided into vertical portion, hook portion and transverse part.On the transverse part of fixed mount, there is the threaded rod of adjustable shelf to pass, and by swing handle, can complete the lifting moving of adjustable shelf.The lower end of adjustable shelf is connected with removable cross bar, there is positioning and guiding pipe removable cross bar outer end, positioning and guiding pipe hollow, the opening of its upper end is through removable cross bar, lower end indentation, and positioning and guiding Guan center is vertical corresponding up and down with the hook portion tip of fixed mount.
For intertrochanteric fracture of the femur, merge little tuberosity fracture patient, after in art, incision appears, because cannot look at little tuberosity straight, available finger touches the little tuberosity of femur, the hook portion tip of fracture reposition instrument is hooked to the center position of little tuberosity, then by swing handle, adjustable shelf is declined, indentation position, positioning and guiding pipe lower end is stuck in lateral side of femur face, then is further rotated swing handle, and the hook portion gap of removable cross bar and fixed mount is dwindled, the little tuberosity sclerite of femur is also resetted completely simultaneously
Now positioning and guiding Guan center is most advanced and sophisticated completely corresponding with the hook portion of fixed mount, with drill bit, by positioning and guiding pipe bit hole, reaches the little tuberosity sclerite of femur, selects appropriate length screw to screw in fixing.
Good reset is fixedly the prerequisite that ensures patient satisfaction, and the present invention can effectively avoid the medical tangle that causes therefrom and the generation of accident, and this apparatus can repeated disinfection use, and production cost is lower, can significantly improve economic benefit and social benefit.
