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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing:
1, adjustable shelf; 2, swing handle; 3, fixed mount; 4, positioning and guiding pipe.
11, threaded rod; 12, removable cross bar; 13, sliding sleeve.
31, transverse part; 32, vertical portion; 33, hook portion.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is 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 preferred implementation of the present utility model; not design of the present utility model and scope are limited; do not departing under the prerequisite of this utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model; all should fall into protection domain of the present utility model; the technology contents that this utility model is asked for protection, is all documented in claims.
This utility model 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
