Description

Technical Field

[0001] The present invention relates to the field of recovery after hip replacement surgery, and specifically provides a rehabilitation device and a rehabilitation method for hip dislocation after hip replacement surgery. Background Art

[0002] Developmental Dysplasia of the Hip (DDH) is a common disease that causes hip pain and dysfunction. It includes a series of hip abnormalities, such as instability, acetabular dysplasia and dislocation. Hip dislocation refers to the loss of the original normal aligning relationship of the bones that make up the joint, including subluxation and dislocation. The most serious is total dislocation of the hip. Total dislocation means that there is no connection between the acetabulum and the femoral head, and the hip joint is completely out of the acetabulum, so hip replacement surgery is required.

[0003] Before hip replacement, it is necessary to accurately assess the degree of hip joint disease, bone condition, soft tissue condition, etc. in order to develop a suitable surgical plan. Due to the poor tolerance of the acetabulum, the femoral head dislocates upward to form a "false acetabulum" in high-dislocated Crowe type IV DDH, which leads to unequal length of the patient's lower limbs and a limping gait. Therefore, severe hip pain will occur in late secondary hip osteoarthritis, and total hip arthro plasty (THA) is often the only effective treatment. During hip replacement, the femoral head is often reconstructed in the true acetabulum, and a subtrochanteric shortening osteotomy and prosthesis placement are performed to ensure that the hip joint can be successfully repositioned and the patient's lower limbs are equal in length. The operation is difficult and the process is complicated. Due to long-term hip dislocation, DDH patients have poor development and weak muscles of the gluteus medius, the most important abductor muscle of the hip joint. In addition, the rotation center of the hip joint changes greatly after surgery compared to before surgery, which leads to the elongation of the gluteus medius, which makes the exercise and rehabilitation of the gluteus medius much more difficult than ordinary joint replacement. Once the gluteus medius is weak, it will cause the patient to have obvious limping. However, the existing technology lacks effective means to improve the condition of the gluteus medius and promote the rehabilitation of the gluteus medius after hip replacement. Studies have shown that 44% of patients have limping caused by gluteus medius weakness during follow-up 9 years after replacement. Therefore, how to improve the condition of the gluteus medius and promote the rehabilitation of the gluteus medius after hip replacement has become a technical problem that needs to be solved urgently.

[0047] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

For example, although the description is based on the abductor muscles of the hip joint, it can be understood by those skilled in the art that the abductor muscles of the hip joint include the gluteus medius, gluteus minimus, tensor fasciae latae and minor hip abductor muscles, so the objects of action of the rehabilitation device and rehabilitation method of the present invention include all of the above muscle groups.

[0048] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0049] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] First, the application scenario of the solution proposed in the present invention is described.

[0051] Reference Figure 1 , Figure 2 Hip dislocation refers to the loss of the original normal apposition relationship of the bones that constitute the joint, including subluxation and full dislocation. Full dislocation means that there is no connection between the acetabulum and the femoral head, and the hip joint is completely out of the acetabulum, so hip replacement is required. During hip replacement, due to the high dislocation of the affected side, not only acetabulum reconstruction and femoral head replacement are required, but also subtrochanteric osteotomy is required to ensure that the hip joint can be smoothly reset and the patient's lower limbs are equal in length. Due to long-term hip dislocation, the most important abductor muscle of the hip joint, the gluteus medius, is poorly developed and weak in muscle. In addition, the rotation center of the hip joint after surgery has changed significantly compared to before surgery, resulting in the elongation of the gluteus medius, which in turn makes the exercise and rehabilitation of the gluteus medius much more difficult than ordinary joint replacement. Once the gluteus medius is weak, it will cause the patient to have obvious limping. Therefore, how to improve the condition of the gluteus medius and promote the rehabilitation of the gluteus medius after hip replacement has become a technical problem that needs to be solved urgently. For this purpose, the following implementation method is proposed.

[0052] Embodiment 1

[0053] like Figure 3As shown, in order to solve the problem in the prior art of poor effect in improving the condition of the gluteus medius muscle and promoting the rehabilitation of the gluteus medius muscle after hip replacement surgery, the present invention proposes a rehabilitation device 1 for hip dislocation after joint replacement surgery, the rehabilitation device 1 includes an electrical stimulation module 11, the electrical stimulation module 11 includes a current generating part 111 and an electrode sheet 112, the electrode sheet 112 is electrically connected to the current generating part 111 and the electrode sheet 112 is arranged at the abductor muscle of the hip joint. The current generating part 111 includes a first gear component and a second gear component. The first gear component is a conductive rod 1111, which is connected to the electrode sheet 112. The second gear component is a gear slot 1112. At least two gear sheets 1113 are arranged in the gear slot 1112. The gear sheets 1113 are connected to a power source and different gear sheets 1113 connect to different currents after being connected to the power source. The conductive rod 1111 is mechanically connected to the abductor muscle of the hip joint and is telescopically arranged in the gear slot 1112. As the position of the conductive rod 1111 in the gear slot 1112 changes, the conductive rod 1111 can contact the gear sheets 1113 at different positions. The electrical stimulation module 11 also includes a first fixing part 113 and a second fixing part 114. The first fixing part 113 and the second fixing part 114 are fixing straps, and the first fixing part 113 is used to fix the electrode sheet 112 to the abductor muscle of the patient's hip joint. The second fixing part 114 is connected to the current generating part 111 and fixed to the patient's buttocks, and is used to fix the current generating part 111.

[0054] In the case of adopting the above-mentioned embodiment, during the use of the postoperative rehabilitation device 1 for hip dislocation of the present invention, the electrode sheet 112 is first fixed to the patient's hip abductor muscle by the first fixing part 113, and the current generating part 111 is fixed by the second fixing part 114. Then, the conductive rod 1111 is placed in the gear slot 1112 and the conductive rod 1111 is adjusted to contact with the appropriate gear sheet 1113, and the current generating part 111 is started to generate current and transmit it to the electrode sheet 112 through the conductive rod 1111 to stimulate the patient's hip abductor muscle with current, so as to achieve the purpose of stimulating the muscle and promote the rehabilitation of the hip abductor muscle including the gluteus medius. Since the current stimulation needs to last for a certain period of time, the patient's hip joint will inevitably move during this period, and the stimulation effect achieved by the stimulation current of different sizes in the contraction and relaxation state of the muscle is also quite different. When the muscle contracts, the muscle begins to contract only when the electrical stimulation intensity reaches the threshold intensity, and as the stimulation intensity increases, the muscle contraction increases. After reaching the maximum stimulation intensity, the muscle contraction no longer increases. When the muscles are in a relaxed state, a current of a relatively low intensity can produce a stimulating effect, but will not cause obvious muscle contraction. Therefore, in this embodiment, the conductive rod 1111 is connected to the electrode sheet 112. When the patient's hip joint moves, the electrode sheet 112 moves with the patient's hip joint and drives the conductive rod 1111 in the gear slot 1112, thereby changing the gear sheet 1113 that the conductive rod 1111 contacts in the gear slot 1112, and then adjusting the magnitude of the stimulating current, so that the magnitude of the stimulating current can change with the contraction / relaxation state of the patient's hip abductor muscles, ensuring the stimulating effect, and solving the problem of poor improvement of the condition of the gluteus medius muscle and promotion of gluteus medius muscle rehabilitation after hip replacement surgery in the prior art.

[0055] It is also worth mentioning that the connection between the electrode sheet 112 and the conductive rod 1111 can be a hard connection or a soft connection. The technicians in this field can adjust the connection mode between the electrode sheet 112 and the conductive rod 1111 according to actual needs, as long as the corresponding technical effect can be achieved, and the present invention does not make specific restrictions on this. In addition, regarding the number of gear plates 1113 in the gear slot 1112, the technicians in this field can set it to two, three, four or other numbers not less than two according to needs, and the present invention does not make specific restrictions on this.

[0056] Embodiment 2

[0057] In the aforementioned embodiment 1, the first gear component and the second gear component are respectively the conductive rod 1111 and the gear slot 1112, while in the present embodiment, the first gear component and the second gear component are respectively the gear knob and the sliding rheostat (not shown in the figure), the first end of the sliding rheostat is connected to the power supply, the second end is mechanically connected to the electrode sheet 112, and the gear knob is connected to the sliding contact of the sliding rheostat.

[0058] In the case of adopting the above embodiment, different from the above-mentioned embodiment 1, the electrode sheet 112 in this embodiment is connected to the gear knob and can drive the gear knob to rotate, and the gear knob drives the sliding contact of the sliding rheostat to move to change the resistance value of the sliding rheostat, thereby changing the magnitude of the stimulation current delivered by the power supply to the electrode sheet 112. This embodiment proposes another form of the first gear component and the second gear component.

[0059] In a possible implementation, the electrical stimulation module 11 further includes an angle sensor, which is arranged at the hip joint and used to obtain the opening angle of the hip joint. The current generating unit 111 further includes a driving device, which is electrically connected to the angle sensor and used to drive the first gear component to move relative to the second gear component. Both the driving device and the angle sensor are connected to the controller of the electrical stimulation module in communication. The opening angle of the patient's hip joint is obtained through the angle sensor, and the position of the first gear component relative to the second gear component is adjusted by the driving device based on the opening angle of the hip joint, thereby adjusting the magnitude of the stimulation current so that the magnitude of the stimulation current can change with the contraction / relaxation state of the patient's hip abductor muscles to ensure the stimulation effect.

[0060] Embodiment 3

[0061] like Figure 4 As shown, the postoperative rehabilitation device 1 for hip dislocation joint replacement of the present invention also includes a fumigation module 12, and the fumigation module 12 includes a steam generator 121 and a steam belt 122. The steam generator 121 is used to generate fumigation steam, and the steam belt 122 is arranged at the abductor muscles of the hip joint. The steam generator 121 is connected to the steam belt 122 and the steam generated by the steam generator 121 can be transported to the abductor muscles of the hip joint for fumigation through the steam belt 122.

[0062] In the case of adopting the above-mentioned embodiment, during the use of the post-operative rehabilitation device 1 for hip dislocation of the present invention, the steam belt 122 is first arranged on the abductor muscles of the patient's hip joint, and then the fumigation liquid is injected into the steam generator 121, and the steam generator 121 is turned on to generate fumigation steam. The fumigation steam is transported to the abductor muscles of the patient's hip joint through the steam belt 122 to fumigate the affected area.

[0063] The advantage of the above embodiment is that by fumigating the abductor muscles of the patient's hip joint, the effect of improving muscle weakness can be achieved. It can be understood by those skilled in the art that in order to achieve a better postoperative rehabilitation effect, the patient's affected part can be electrically stimulated first and then fumigated, or fumigated first and then electrically stimulated, and these changes do not exceed the scope of protection of the present invention.

[0064] Embodiment 4:

[0065] The present invention also provides a method for rehabilitation after joint replacement for hip dislocation, comprising the apparatus 1 for rehabilitation after joint replacement for hip dislocation in the first embodiment, as shown in FIG. Figure 5 , Figure 7 and Fig.12 As shown, rehabilitation methods include:

[0066] S1. Fix the electrode sheet 112 to the Chengfu, Zhibian, Huantiao and Biguan acupoints through the first fixing part 113;

[0067] S2, fixing the current generating unit 111 through the second fixing unit 114;

[0068] S3. Adjust the position of the first gear component relative to the second gear component to adjust the magnitude of the current generated by the current generating unit 111.

[0069] In the above steps, step S3 further comprises:

[0070] S31, driving the conductive rod 1111 to move in the gear slot 1112 through the abductor muscles of the hip joint and contacting the gear pieces 1113 at different positions to adjust the magnitude of the current generated by the current generating part 111.

[0071] In the case of adopting the above-mentioned embodiment, the electrode sheet 112 is first fixed to the patient's Chengfu, Zhibian, Huantiao, and Biguan acupoints through the first fixing part 113, and then the current generating part 111 is fixed through the second fixing part 114. After the fixing is completed, the current generating part 111 is started, and the magnitude of the current generated by the current generating part 111 can be adjusted by adjusting the position of the first gear component relative to the second gear component to ensure the stimulation effect, thereby solving the problem of poor effect in improving the condition of the gluteus medius muscle and promoting the rehabilitation of the gluteus medius muscle after hip replacement surgery in the prior art. In addition, when adjusting the position of the first gear component relative to the second gear component, the technicians in this field can manually switch the gear, or connect the first gear component to the electrode sheet 112 in the first embodiment, and adjust the position of the first gear component relative to the second gear component according to the contraction / relaxation state of the patient's hip abductor muscle. These methods can all adjust the magnitude of the current generated by the current generating part 111, and are also within the protection scope of the present invention.

[0072] In a possible implementation, the electrical stimulation module 11 further includes an angle sensor, which is arranged at the hip joint and is used to obtain the opening angle of the hip joint. The current generating unit 111 further includes a driving device, which is electrically connected to the angle sensor and is used to drive the first gear component to move relative to the second gear component. The driving device and the angle sensor are both connected to the controller of the electrical stimulation module for communication. Fig.13 As shown, step S3 also includes:

[0073] S32, controlling the angle sensor to obtain the opening angle of the hip joint;

[0074] S33, comparing the opening angle of the hip joint with a preset opening angle;

[0075] S34 , adjusting the position of the first shift component relative to the second shift component based on the comparison result to adjust the magnitude of the current generated by the current generating unit 111 .

[0076] In the case of adopting the above embodiment, after the electrode sheet 112 is fixed, the angle sensor is controlled to obtain the opening angle of the hip joint, and then the opening angle of the hip joint is compared with the preset opening angle. When the opening angle of the hip joint reaches the preset angle of the first gear, the driving device is controlled to drive the first gear component to move to the first gear. When the patient moves the hip joint so that the opening angle of the hip joint reaches the preset angle of the second gear, the driving device is controlled to drive the first gear component to move to the second gear, thereby adjusting the size of the stimulation current so that the size of the stimulation current can change with the contraction / relaxation state of the patient's hip abductor muscles to ensure the stimulation effect.

[0077] Embodiment 5

[0078] The rehabilitation device 1 of the present invention may further include a fumigation module 12, the fumigation module 12 includes a steam generator 121 and a steam belt 122, the steam generator 121 is used to generate fumigation steam, the steam belt 122 is arranged at the place to be fumigated, the steam generator 121 is connected to the steam belt 122, and the steam generated by the steam generator 121 can be transported to the fumigation place through the steam belt 122 for fumigation, such as Figure 8-Figure 10 As shown, rehabilitation methods also include:

[0079] S4, preparing fumigation Chinese medicine solution;

[0080] S5, injecting the fumigation Chinese medicine liquid into the steam generator 121;

[0081] S6, placing the steam belt 122 at the place to be fumigated;

[0082] S7, start the steam generator 121 to fumigate the area to be fumigated.

[0083] In the above steps, step S4 further comprises:

[0084] S41, take 30 grams of Astragalus and Millettia reticulata Chinese medicine slices, wash them, add water in a ratio of 1:5 to submerge the herbs and soak them for one hour;

[0085] S42, pour into a medicine decoction machine, boil for 45 minutes, and then filter to obtain the fumigated Chinese medicine liquid.

[0086] Step S6 further comprises:

[0087] S61. Place the steam belt 122 on the abductor muscles of the hip joint.

[0088] In the case of adopting the above-mentioned embodiment, the postoperative rehabilitation method for hip dislocation of the present invention can also fumigate the patient's abductor muscles. Specifically, first take 30 grams of each of the Chinese medicinal slices of Astragalus and Millettia Spatholobi, wash them, add water to immerse the medicinal materials in a ratio of 1:5 to water and soak them for one hour to ensure that the medicinal materials are completely immersed, and then introduce them into the decoction machine for decoction for 45 minutes, and obtain the fumigated Chinese medicinal liquid after filtering. Subsequently, the steam belt 122 is arranged at the abductor muscles of the hip joint, and the steam generator 121 is started to fumigate the affected part of the patient. According to traditional Chinese medicine theory, the spleen governs the muscles of the limbs, Astragalus invigorates the spleen and replenishes qi, and Millettia Spatholobi nourishes blood and activates blood circulation. The two medicines have the effect of improving postoperative muscle weakness. Modern pharmacological studies have shown that the main effective active ingredients of Astragalus can not only reduce muscle protein decomposition by inhibiting the ubiquitin-proteasome pathway, but also activate the mTOR signaling pathway to promote protein synthesis.

[0089] In addition, in order to further ensure the rehabilitation effect of the hip abductor muscles of the patient after surgery, technicians in this field can also combine the electrical stimulation module 11 in Example 4 for treatment. These changes are all within the protection scope of the present invention.

[0090] Embodiment 6

[0091] Studies have shown that 29% of cases of subtrochanteric osteotomy nonunion occurred during 9-year follow-up after hip replacement surgery. However, existing medical methods cannot effectively promote the healing of the osteotomy growth area. In order to avoid slow growth or nonunion of the osteotomy area, it is necessary to stimulate local femoral growth and reduce the incidence of nonunion. For this reason, this embodiment is proposed. In this embodiment, if Fig.11 As shown, step S4 also includes:

[0092] S43, take 30g each of Chuanxiong, Panax notoginseng, Radix Angelicae Pubescentis, Myrrha, Dipsacus asper, and Rhizoma Drynariae, wash them, add water in a ratio of 1:5 to cover the herbs, and soak for one hour;

[0093] S44, pour into a medicine decoction machine, boil for 45 minutes, and then filter to obtain the fumigated Chinese medicine liquid.

[0094] The preparation of fumigation Chinese medicine liquid and the fumigation process are similar to those in the above-mentioned embodiment 5, and will not be repeated here. Modern pharmacological studies have shown that Chuanxiong can improve local blood stasis after surgery by reducing platelet aggregation, inhibiting angiogenesis in plaques, and promoting fibrinolysis. Chuanxiong can also increase the mitochondrial membrane potential of oxygen-glucose deprivation / reoxygenation primary cerebral cortical neurons, activate cyclic adenosine monophosphate effector element binding protein, reduce the level of reactive oxygen, inhibit the activation of astrocytes, and reduce neuroinflammation through anti-inflammatory and antioxidant pathways, thereby alleviating the pain response caused by neuroinflammation. The blood circulation effect of Panax notoginseng is manifested in promoting the fibrinolytic system, inhibiting platelet aggregation and vasodilation. The two medicines have the effects of improving local blood stasis after surgery and promoting blood circulation and relieving pain. Thus, the scheme of this embodiment can stimulate local growth of the femur and reduce the incidence of non-union. Herba scutellariae inhibits the production of IL-1β in inflammatory tissues and reduces inflammatory reactions, so it has a certain anti-inflammatory effect to reduce edema. The main chemical components of myrrh are terpenoid compounds, which have anti-inflammatory, analgesic and other biological activities. The two drugs are matched to eliminate postoperative swelling. Dipsacus root has the effect of promoting the formation and proliferation of osteoblasts and accelerating fracture healing and repair. The main active ingredients of Drynaria are Drynaria total flavonoids and naringin, which can regulate bone metabolism, inhibit osteoblast apoptosis, promote osteoblast proliferation and differentiation, thereby increasing new bone formation, and inhibit osteoclast maturation and proliferation to reduce bone absorption. Both drugs can nourish the liver and kidney, strengthen tendons and bones, and heal fractures, playing a role in promoting postoperative bone healing.

[0095] In addition, regarding the weight of medicinal materials and decoction time in the process of preparing the fumigated Chinese medicine solution, technicians in this field can make appropriate adjustments according to actual conditions. These changes do not exceed the technical principles of the present invention and are therefore included in the protection scope of the present invention.

[0096] In addition, refer to Figure 1 , Figure 2 and Figure 6 Before the operation, the patient's two lower limbs were of unequal length. After the hip replacement surgery, the longer lower limb was osteotomized and the length of the femoral stem was reasonably designed to ensure that the patient's two lower limbs were of equal length. The patient's walking returned to normal and limping was avoided.

[0097] It should be noted that the above-mentioned implementation mode is only used to illustrate the principle of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.

[0098] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
