Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a knee arthritis pressing, stretching and traction therapeutic device. Background Art

[0002] Knee arthritis can cause bow legs, commonly known as "bow legs." This deformity occurs when the inner ankles of the feet touch each other and the knees cannot be brought together when the lower limbs are naturally straightened or standing. Causes of this condition include skeletal development disorders during development, bone deformation or poor development of articular cartilage, long-term bad habits that cause imbalances in the muscles controlling the joints, trauma, or other diseases. People with bow legs have genu varum, and excessive body weight is concentrated on the medial articular surface of the knee joint, leading to wear of the medial cartilage surface of the knee joint, collapse of the tibial plateau, and secondary osteoarthritis. Leg deformities not only affect appearance and health, but can also cause patients to suffer from negative psychological problems such as low self-esteem.

[0003] Currently, there are two methods for correcting bow legs: surgical and non-surgical. Surgery is suitable for more severe cases and offers quick results, but it carries significant costs and risks. Therefore, there is a need for a knee arthritis compression, stretching, and traction device that continuously stretches and restores the knee ligaments, thereby improving the effectiveness of bow legs treatment and shortening the treatment cycle. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a knee arthritis pressing, stretching and traction therapeutic instrument.

[0005] In order to solve the above technical problems, the technical solution adopted by the present utility model is:

[0006] The knee arthritis pressing, stretching and traction therapeutic device is characterized by comprising:

[0007] A fixed bottom plate, wherein the middle portion of the fixed bottom plate has a guide portion arranged along the length direction of the fixed bottom plate;

[0008] A reduction assembly includes a slide plate, the bottom of which is in sliding engagement with the guide portion, and four traction rods arranged in a rectangular shape on the upper surface of the slide plate. The traction rods are retractable, and universal joints are fixed to both ends of the traction rods. One end of the traction rod is fixed to the slide plate, and the other end is fixed to a reduction plate capable of covering the side of the patient's knee joint. The two reduction plates on the left and right sides are fixed by straps. A support plate is provided below the four reduction plates, which is supported below the patient's knee joint, and its four corners are fixed to the four reduction plates by connecting straps; and

[0009] The traction assembly comprises a traction seat for holding the distal end of the tibia. The bottom of the traction seat is in sliding engagement with the guide portion. A power component for driving the traction seat to move toward the distal end is connected to the traction seat.

[0010] A further technical solution is that the traction seat includes a base and an upper cover, the upper surface of the base is a downwardly concave arc surface, and an airbag cushion connected to the inflation and deflation assembly is provided on the arc surface, and the upper cover is arc-shaped and buckled into the upper part of the base, and can be locked or opened with the base.

[0011] A further technical solution is that the power component includes:

[0012] A take-up shaft is laterally located at the distal end of the traction seat, with both ends of the take-up shaft rotatably fixed to the fixed base plate, and one end is connected to a motor driving the take-up shaft to rotate, and a take-up wheel is fixed on the take-up shaft;

[0013] A guide shaft is arranged parallel to the winding shaft and is located between the winding shaft and the traction seat. Both ends of the guide shaft are rotatably fixed to the fixed base plate, and a guide wire wheel is fixed on the guide shaft; and

[0014] One end of the traction line is fixed to the connecting column above the traction seat, and the other end can be led out horizontally and wound around the guide wheel and then wound around the winding wheel.

[0019] A further technical solution is that the length of the connecting belt is adjustable.

[0020] A further technical solution is that the four reset plates are fixed by two cross-arranged straps.

[0021] The beneficial effects of adopting the above technical solution are:

[0022] During treatment, the patient lies on a fixed base plate and fixes the knee joint with the reduction plate on the four traction rods in the reduction assembly. The deformation of the four traction rods can reduce the valgus of the knee joint, and then the contraction of the four traction rods can achieve downward pressure on the knee joint. During the downward pressure process, the knee joint will move distally in space. The displacement can be adapted by sliding the slide board, thereby achieving reduction exercise for the valgus and downward pressure of the knee joint and correcting bone displacement.

[0023] In addition, the traction component pulls the distal end of the affected limb to further assist in reduction, allowing the knee joint ligaments to continue to stretch and recover, thereby improving the treatment effect of bow legs. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1 and Figure 2 As shown, the knee arthritis pressing, stretching and traction therapeutic device includes a fixed base plate 10, a reduction component 20 and a traction component.

[0030] The middle part of the fixed base plate 10 is provided with a guide portion 11 arranged along its length. The guide portion 11 can be a raised guide rail or a recessed guide groove. The reset assembly 20 includes a slide plate 21. The bottom of the slide plate 21 has a slider that is engaged with the guide portion 11, so that the slide plate 21 and the guide portion 11 are in sliding engagement, so that the slide plate 21 can slide along the guide portion 11. There are four traction rods 22 arranged in a rectangular shape on the upper surface of the slide plate 21. The traction rods 22 can be telescopic. The traction rods 22 can be in the form of a cylinder, an oil cylinder or an electric telescopic rod. Universal joints are fixed at both ends of the traction rods 22. One end of the traction rod 22 is fixed to the slide plate 21, and the other end is fixed with a reset plate 23 that can cover the left and right sides of the patient's knee joint. The two reset plates 23 on the left and right sides are fixed by a strap. Preferably, the two reset plates 23 at opposite corners are fixed by a strap, and the two straps are fixed crosswise. There is a support plate 24 below the four reset plates 23. The support plate 24 is supported below the patient's knee joint, and its four corners are fixed to the four reset plates 23 by connecting belts. The reset plate 23 and the support plate 24 are preferably arc-shaped, which can better adapt and fit the patient's knee joint. The length of the connecting belt is adjustable, and the length can be adjusted by providing buckles or Velcro on the belt to accommodate patients of different body shapes. When the four reset plates 23 and the support plate 24 are fixed around the knee joint, the four traction rods 22 are in the form of a quadrangular pyramid. In addition, a disposable gel patch is pasted on the inner side of the reset plate 23. The provision of the gel patch can increase the comfort of the patient.

[0031] During treatment, the patient lies on the fixed base plate 10 and fixes the knee joint with the reset plate 23 on the four traction rods 22 in the reset assembly 20. The knee joint can be reset due to the deformation of the four traction rods 22, and then the knee joint is pressed downward by the contraction of the four traction rods 22. During the downward pressure, the knee joint will be displaced distally in space, and the displacement can be adapted by the sliding of the slide plate 21, thereby achieving the reset exercise of the knee joint valgus and downward pressure, and correcting bone displacement.

[0032] The traction assembly includes a traction seat 31 for holding the distal end of the tibia. The bottom of the traction seat 31 is in sliding engagement with the guide portion 11 . A power component is connected to the traction seat 31 to drive it to move toward the distal end.

[0033] The traction seat 31 comprises a base and a cover. The base's upper surface is a downwardly concave arc, housing an airbag cushion connected to the inflation and deflation assembly. The arc-shaped cover snaps onto the upper portion of the base, allowing for locking and unlocking. The airbag cushion and base are secured with Velcro. The secondary and primary Velcro strips secure the cushion and base, respectively, facilitating assembly and disassembly, as well as cleaning and disinfection. The airbag cushion's varying inflation levels can accommodate patients of varying body shapes.

[0034] In addition, the traction component pulls the distal end of the affected limb to further assist in reduction, allowing the knee joint ligaments to continue to stretch and recover, thereby improving the treatment effect of bow legs.

[0035] The power assembly includes a reel 32, a guide shaft 33, and a traction line 34. The reel 32 is located transversely at the distal end of the traction seat 31. Both ends of the reel 32 are rotatably fixed to the fixed base plate 10, and one end is connected to a motor 322 that drives its rotation. A reel 321 is fixed to the reel 32. The guide shaft 33 is arranged parallel to the reel 32 and located between the reel 32 and the traction seat 31. Both ends of the guide shaft 33 are rotatably fixed to the fixed base plate 10 via bearings, and a guide line reel 331 is fixed to the guide shaft 33. One end of the traction line 34 is fixed to a connecting post above the traction seat, while the other end can be drawn out horizontally, wrapped around the guide line reel 331, and then wound around the reel 321.

[0036] By driving the reel 32 to rotate forward or reverse, the traction line 34 can be reeled in and secured. When the fixed seat needs to be pulled to the far end, the reel 32 is rotated and the traction line 34 is wound around the reel wheel 321, which can pull the fixed seat to the far end.

[0037] The setting of the guide shaft 33 can ensure that the traction line 34 is led out horizontally, so that the traction force is pulled in the horizontal direction.

[0038] The traction seat 31 and the slide plate 21 are connected as one body via a connector 40. This allows the power member to simultaneously pull the distal tibia and the knee joint during traction, continuously stretching and restoring the knee ligaments, thereby improving the treatment effect of bow legs. The connector 40 is an adjustable length connecting rod to accommodate patients of different heights.

[0039] In addition, the fixed base plate 10 has a space for the patient to lie down on both sides of the guide portion 11, and is paved with soft cushions. By changing the position where the patient lies, patients on different sides can be treated.

[0040] The above are only preferred embodiments of the present invention. Any simple modification, deformation and equivalent replacement made by anyone to the present invention based on the content of the present invention shall fall within the protection scope of the present invention.
