Description
Technical field
This utility model relates to a kind of surgical postoperative medical apparatus and instruments, is particularly a kind ofly applicable to the postoperative rehabilitation appliances preventing cicatricial contracture of elbow joint.
Background technology
At present, elbow joint Post operation, can cause cicatricial contracture after the cicatrix healing at operative incision place, and the strength of cicatricial contracture is very large, and in the cicatrix agglutination of extensive tissue defect, the strength of its contracture is cumulative property.Before wound does not heal in early days, the activity of limbs and profile can be close to normally; Once healing, its contracture strength increases, and the lighter is skin and sub-dermal soft tissue contracture, and severe one can cause muscle, tendon, blood vessel, neural cripetura, even deformity of joint, contracture for many years, limbs distortion can be caused to be serpentine deformity, completely lose work function.The strength of cicatricial contracture can exceed the tension force of bone, joint, ligament, tendon, makes joint distortion, subluxation of joint or dislocation.Therefore, just need a kind ofly can help the postoperative rehabilitation appliances preventing cicatricial contracture of patient articular.
Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, provides a kind of and is applicable to the postoperative rehabilitation appliances preventing cicatricial contracture of elbow joint.
The technical scheme in the invention for solving the technical problem is: the apparatus preventing elbow joint postoperative scar contracture, is characterized in that: comprise Double shaft-extension motor, frame, supporting plate and fixing head; The both sides of described supporting plate and frame are for being rotatably connected, the left side of supporting plate is connected with the first half-ring gear, the right side of supporting plate is connected with the second half-ring gear, and the both sides of described supporting plate are connected with one end of connecting plate respectively, and the other end of connecting plate and the both sides of fixing head are for being fixedly connected with; Described frame is provided with a motor rack, described motor rack is provided with Double shaft-extension motor, and the two ends of described Double shaft-extension motor are respectively equipped with a turning cylinder; The turning cylinder in the left side of described Double shaft-extension motor is connected with the first half gears, and the turning cylinder on right side is connected with the second half gears, and described the first half gears and the second half gears are installed in opposite directions; Described the first half gears in rotation process can with supporting plate on the left of the first half-ring gear internal messing; The right side of described frame and a travelling gear for being rotatably connected, described the second half gears in rotation process can with travelling gear external toothing, the second half-ring gear on the right side of described travelling gear and supporting plate is internal messing.
Compared with prior art, this utility model has following outstanding beneficial effect:
1, this utility model structure is simple, reasonable in design, simple to operate;
2, this utility model can carry out passive flexion and extension exercise to elbow joint place, prevents cicatricial contracture, and effect certainly.

Fig. 1 is top view of the present utility model.
Fig. 2 is left view of the present utility model.
Fig. 3 is right view of the present utility model.
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.
As shown in Figure 1,2 and 3, this utility model comprises Double shaft-extension motor 6, frame 2, supporting plate 1 and fixing head 11.
Convenient in order to describe, below alleged " left side " " right side " consistent with the left and right directions of Fig. 1 itself.As shown in Figure 1, the both sides of described supporting plate 1 and frame 2 are for being rotatably connected, the left side of supporting plate 1 is connected with the first half-ring gear 4, the right side of supporting plate 1 is connected with the second half-ring gear 7, the both sides of described supporting plate 1 are connected with one end of connecting plate 10 respectively, and the other end of connecting plate 10 and the both sides of fixing head 11 are for being fixedly connected with.Described frame 2 is provided with a motor rack 3, and described motor rack 3 is provided with Double shaft-extension motor 6, and the two ends of described Double shaft-extension motor 6 are respectively equipped with a turning cylinder.
In prioritization scheme, described fixing head 11 has binding strip.
The turning cylinder in the left side of described Double shaft-extension motor 6 is connected with the first half gears 5, and the turning cylinder on right side is connected with the second half gears 8, and described the first half gears 5 and the second half gears 8 are installed in opposite directions.Described the first half gears 5 in rotation process can with supporting plate 1 on the left of the first half-ring gear 4 internal messing.The right side of described frame 2 and a travelling gear 9 for being rotatably connected, described the second half gears 8 in rotation process can with travelling gear 9 external toothing, described travelling gear 9 is internal messing with the second half-ring gear 7 on the right side of supporting plate 1.When starting Double shaft-extension motor 6, the first half gear 5 and the first half-ring gear 4 internal messing, the first half gears 5 drive the first half-ring gear 4 to rotate, and the first half gears 5 are identical with the first half-ring gear 4 direction of rotation.When the first half gears 5 and the first half-ring gear 4 depart from engage time, the second half gears 8 are meshed with travelling gear 9, due to the second half gears 8 and travelling gear 9 external toothing, so the second half gears 8 are contrary with travelling gear 9 direction of rotation, due to travelling gear 9 and the second half-ring gear 7 internal messing, so travelling gear 9 is identical with the second half-ring gear 7 direction of rotation, thus supporting plate 1 can be realized drives fixing head 11 to do reciprocally swinging.
Operating process is as follows: when using this utility model, patient is sitting on chair, forearm to be placed on fixing head 11 and to fix, be half flexion under upper arm and forearm naturalness, start Double shaft-extension motor 6, Double shaft-extension motor 6 drives the first half gears 5 to rotate, the first half gears 5 and the first half-ring gear 4 enter engagement, due to the first half gear 5 and the first half-ring gear 4 internal messing, the first half gears 5 are identical with the first half-ring gear 4 direction of rotation, the first half gears 5 drive the first half-ring gear 4 to rotate, and supporting plate 1 is identical with the direction of rotation of Double shaft-extension motor 6.When the first half gears 5 and the first half-ring gear 4 depart from engage time, the second half gears 8 enter engagement with travelling gear 9, due to the second half gears 8 and travelling gear 9 external toothing, so the second half gears 8 are contrary with travelling gear 9 direction of rotation, due to travelling gear 9 and the second half-ring gear 7 internal messing, so travelling gear 9 is identical with the second half-ring gear 7 direction of rotation, supporting plate 1 is contrary with the direction of rotation of Double shaft-extension motor 6, thus can fixing head 11 be driven to do reciprocally swinging by real supporting plate 1, continuous change upper arm and forearm angle, namely the flexion-extension motion of elbow joint is completed, back and forth can train the elbow joint of patient.
It should be noted that; particular of the present utility model has been described in detail this utility model; for a person skilled in the art, the various apparent change carried out it when not deviating from spirit and scope of the present utility model is all within protection domain of the present utility model.
