Description

Hip Fixation Device

This invention relates to a medical device, in particular to a hip joint fixation device used after surgery.

The hip joint is severely degenerated, necrosis, rheumatoid arthritis, trauma or disease, resulting in functional impairment that affects normal life, pain and discomfort, and even inconvenience in movement and inability to take care of oneself. When the symptoms cannot be alleviated by medication or other methods, the doctor may choose to replace the artificial hip joint through surgery. After the operation, the artificial hip joint will be suspended due to the patient's habit of crossing his legs; or the artificial hip joint will be retracted due to the patient's habit of lying flat or lying on his side, which can easily cause postoperative hip dislocation. Therefore, in order to avoid artificial hip dislocation, the commonly used method is to place a pillow between the patient's legs so that the patient's legs can be kept in an abducted position of about 15 to 30 degrees.

However, when the patient is sleeping or has a disordered consciousness, the pillow cannot be fixed to the patient's legs, so the patient's legs cannot be kept in the predetermined abduction position, resulting in the risk of retraction and dislocation of the artificial hip joint.

In view of this, the conventional hip joint fixation methods still need to be improved.

To solve the above problems, the purpose of this invention is to provide a hip joint fixation device that can be fixed between the legs of a user to improve the convenience of use.

A second object of the present invention is to provide a hip joint fixation device that can reduce the overall volume of the hip joint fixation device to save storage space.

Another object of the present invention is to provide a hip joint fixation device that can reduce manufacturing costs.

Another object of the present invention is to provide a hip joint fixation device that can improve the comfort of use.

In order to make the above and other purposes, features and advantages of this creation more clearly understood, the following specifically cites a preferred embodiment of this creation and provides a detailed description in conjunction with the attached drawings; in addition, items marked with the same symbols in different drawings are deemed to be the same and their descriptions will be omitted.

Please refer to FIG. 1 , which is a preferred embodiment of the hip joint fixing device of the present invention, comprising a main body 1 and a plurality of belt bodies 2 , wherein the plurality of belt bodies 2 are connected to the main body 1 .

Please refer to FIG. 1. The frame body 1 can be used to be assembled between the legs (as shown in FIG. 4). The frame body 1 has a fixed frame 1a and a rotating frame 1b. The rotating frame 1b is rotatably connected to the fixed frame 1a. In detail, the fixed frame 1a can have a coupling seat 11 and a first bracket 12. The first bracket 12 can be connected to the coupling seat 11 and extend in a direction away from the coupling seat 11. Preferably, the first bracket 12 can be integrally formed and connected with the coupling seat 11 to enhance the structural strength of the fixed frame 1a. Among them, the fixed frame 1a can have a plurality of clamping grooves 13, and each of the clamping grooves 13 can be located on the coupling seat 11.

Please refer to Figures 1 and 2. The rotating frame 1b may have a connecting portion 14 and a second bracket 15. The connecting portion 14 may be pivotally connected to the coupling seat 11 via a coupling member F. The rotating frame 1b may have a central axis X at the coupling member F. The second bracket 15 may rotate toward the first bracket 12 or away from the first bracket 12 with the central axis X as the axis, so that the rotating frame 1b may be rotatably coupled to the fixed frame 1a. In addition, the second bracket 15 may be connected to the connecting portion 14 and extend in a direction away from the connecting portion 14, so that the second bracket 15 may be aligned with the first bracket 12. Preferably, the second bracket 15 may be integrally connected to the connecting portion 14 to enhance the structural strength of the rotating frame 1b.

Thus, when the second bracket 15 rotates toward the first bracket 12 with the central axis X as the axis, the second bracket 15 can be close to the first bracket 12 as shown in FIG. 2, so that the overall volume of the hip joint fixing device of the invention can be reduced, thereby saving storage space. Moreover, when the second bracket 15 rotates away from the first bracket 12 with the central axis X as the axis, the second bracket 15 and the first bracket 12 can be unfolded as shown in FIG. 3, so that the rotating frame 1b and the fixed frame 1a can have an unfolding angle θ as shown in FIG. 4.

As shown in FIG. 1 , in addition, the rotating frame 1b may have an operating member 16, and the operating member 16 may be disposed on the connecting portion 14. The operating member 16 may have an operating end 16a and a limiting end 16b, and the limiting end 16b is closer to the plurality of clamping slots 13 than the operating end 16a, and the limiting end 16b may be used to be clamped in one of the plurality of clamping slots 13. Furthermore, the operating member 16 may have an abutting piece 161, and the abutting piece 161 may be located between the operating end 16a and the limiting end 16b. It is also explained that the method of combining the operating member 16 and the connecting part 14 is based on the principle that the operating member 16 can be stably set on the connecting part 14, and the present invention is not limited to this. In this embodiment, the rotating frame 1b can have two positioning plates 17, each of which can be locked on the connecting part 14, and the operating member 16 can be inserted into each of the positioning plates 17, so that the operating member 16 can be combined with the connecting part 14 through each of the positioning plates 17.

Please refer to Figures 2 and 3. In addition, the rotating frame 1b may have a reset element 18. The reset element 18 may be located between each of the positioning pieces 17. The reset element 18 may be a known spring or the like. The reset element 18 may be sleeved on the operating member 16. The reset element 18 may be closer to the operating end 16a than the abutting piece 161, and the two ends of the reset element 18 abut against the abutting piece 161 and the positioning piece 17, respectively. When the operating end 16a of the operating member 16 is stretched, the reset element 18 is squeezed by the abutting piece 161 so that the limiting end 16b of the operating member 16 is not clamped in the clamping groove 13, thereby enabling the second bracket 15 to rotate relative to the first bracket 12 with the central axis X as the axis. When the operating end 16 a of the operating member 16 is not stretched, the operating member 16 can be reset by the elastic restoring force of the reset element 18 , so that the limiting end 16 b of the operating member 16 is locked in the locking groove 13 .

As shown in FIG. 4 , the plurality of belt bodies 2 are connected to the second bracket 15 of the rotating frame 1b and the first bracket 12 of the fixing frame 1a, respectively. Each of the belt bodies 2 can be wrapped around the legs, so that the rotating frame 1b and the fixing frame 1a can be fixed to the legs by each of the belt bodies 2, so that the hip joint fixing device of the invention can be prevented from being separated from between the legs when the user moves the body, which can improve the convenience of use.

The hip joint fixing device of the invention may further include two protective pads 3, each of which may be connected to the outer side of the first bracket 12 and the outer side of the second bracket 15, respectively. Each of the protective pads 3 may be made of soft material, and each of the protective pads 3 may contact the user's legs, thereby preventing the user from feeling uncomfortable and improving the comfort of use. Preferably, each of the protective pads 3 is detachably connected to the first bracket 12 and the second bracket 15, such as by snapping, magnetism or bonding, etc., and the invention is not limited thereto, so that each of the protective pads 3 can be easily removed for regular cleaning.

Please refer to Figures 3 and 4. When the hip joint fixing device of the present invention is used, the medical staff can first wrap the belt bodies 2 located on the fixing frame 1a around the legs, and stretch the operating end 16a of the operating member 16 so that the limiting end 16b of the operating member 16 is not clamped in the clamping groove 13. At this time, the second bracket 15 can rotate in a direction away from the first bracket 12 with the central axis X as the axis, so that the second bracket 15 and the first bracket 12 can be unfolded, so that the rotating frame 1b and the fixing frame 1a can have the unfolding angle θ; then, the belt bodies 2 located on the rotating frame 1b are wrapped around the legs, and the hip joint fixing device of the present invention can be installed between the legs of the user.

Therefore, even if the user has different habits of lying flat or lying on the side, the hip joint fixing device can be fixed between the user's legs so that the legs can be kept in a predetermined abducted position, which can greatly reduce the risk of artificial hip joint contraction and dislocation, and has the effect of improving the convenience of use.

Please refer to FIG. 2. After the hip joint fixation device of the present invention is used, the medical staff can first remove the belt body 2 from the leg, and then stretch the operating end 16a of the operating member 16 so that the limiting end 16b of the operating member 16 is not stuck in the locking groove 13. At this time, the second bracket 15 can rotate toward the direction of the first bracket 12 with the central axis X as the axis, so that the overall volume of the hip joint fixation device of the present invention can be reduced, thereby saving storage space.

In summary, the hip joint fixing device of the invention utilizes the expansion angle between the rotating frame and the fixing frame, and the plurality of straps are respectively connected to the rotating frame and the fixing frame; the hip joint fixing device can be fixed between the legs of the user, so that the legs can be kept in a predetermined abduction position, which can greatly reduce the risk of contraction and dislocation of the artificial hip joint. After use, the overall volume of the hip joint fixing device of the invention can be reduced by rotating the rotating frame toward the fixing frame, which can be convenient to use and save storage space.
