Description

Hemiplegic lower limb orthosis

technical field

The utility model relates to an orthopedic device, in particular to a hemiplegic lower limb orthosis.

Background technique

Hemiplegia, also known as hemiplegia, refers to motor center damage caused by cerebrovascular accident, traumatic brain injury, and brain tumor surgery, resulting in movement disorders of the upper and lower limbs on the opposite side. The traditional treatment methods for hemiplegia are mainly through drugs, acupuncture, massage and rehabilitation training. The patient recovered some physiological functions, but during the rehabilitation training, due to the lack of strength of the patient's side limbs and poor coordination and control ability, uneven weight bearing will appear when standing and walking, the pelvic swing is limited, mopping the floor, drawing circles, and knees passing through when walking. Long-term abnormal gait will lead to aggravated muscle spasms, joint ligament damage, and secondary risks such as easy falls.

Utility model content

In order to solve the above technical problems, the utility model provides a hemiplegic lower limb orthosis that can help hemiplegic patients stand, walk, and correct abnormal movement patterns.

The technical solution is as follows: a hemiplegic lower limb orthosis, comprising a thigh support cover, a calf support cover, a foot support, the foot support includes a foot support plate and an ankle guard plate arranged around the heel of the foot support plate, the thigh A first support rod, a second support rod and a third support rod are respectively fixedly installed on the same side of the support sleeve, the calf support sleeve and the ankle guard, and the upper end of the second support rod is connected to the load-bearing self-locking knee joint The lower end of the first support rod is fixedly connected, and the lower end of the second support rod is hinged to the upper end of the third support rod. The beneficial effect of adopting this scheme is that the support device automatically locks under the action of human body gravity to maintain the stability of the knee joint during the support period and static state of the patient's gait cycle, avoiding falls due to knee joint softening, and during the swing period of walking. When the center of gravity is leaning forward, it will be automatically unlocked, and the swing of the human trunk and thigh will drive the knee joint to flex and swing to complete the walking action. It can effectively correct foot drop, foot inversion, and foot eversion, and keep the ankle joint in a functional position. The whole supporting device assists the patient to complete the walking function without affecting the patient's sitting function.

As a preference: the first support rod, the second support rod and the third support rod are respectively one, and are fixedly installed on the outer side walls of the thigh support sleeve, the calf support sleeve and the ankle guard; such The structure can not only provide stable support but also allow patients to walk more flexibly.

The above-mentioned thigh support sleeve is a cylindrical structure with a first "n"-shaped opening on the front, a first "u"-shaped opening on the upper end of the back, and a second "n"-shaped opening on the lower end. The first "n" The centerlines of the second "n"-shaped opening and the first "u"-shaped opening are parallel to and in the same plane as the centerline of the thigh support sleeve, and the two sides of the first "n"-shaped opening The first fixing belt is provided, and the hollow-out design is conducive to reducing the weight of the thigh support sleeve and reducing the energy consumption of the patient when walking. The first fixing belt can make the fit between the patient's thigh and the thigh support sleeve more stable and reliable.

The calf support sleeve is a cylindrical structure with a half opening on the front, a second "u"-shaped opening on the upper end of the back, and a third "n"-shaped opening on the lower end. The second "u"-shaped opening, the third "n"-shaped opening The centerline of the "shaped opening is parallel to and in the same plane as the centerline of the calf support sleeve. The upper end of the front of the calf support sleeve is provided with a second fixing belt. This hollowed out opening design can reduce the weight of the orthosis on the one hand. , to reduce the physical energy consumption of the patient during walking, on the other hand, it has good air permeability, which can increase the wearing comfort of the patient, and the second fixing belt can make the fit between the patient's calf and the calf support sleeve more stable and reliable.

The above-mentioned foot-ankle shield is provided with a third fixing belt, and this design can make the cooperation between the patient's foot and the foot support more stable and reliable, and allow the patient to walk more flexibly.

The above-mentioned first fixing belt, the second fixing belt and the third fixing belt are all nylon adhesive belts, which are durable and easy to wear.

Pressure pads are provided on the inner walls of the lower ends of both sides of the thigh support sleeve, which can provide better protection for the knee joint and stabilize the knee joint.

The above-mentioned thigh support sleeve, calf support sleeve and foot support are all made of high-temperature thermoplastic board. This material has good air permeability, light weight, high strength, good toughness and is not easy to be damaged or broken.

Beneficial effect: the beneficial effect of adopting the utility model is to prevent and correct the deformed lower limbs of the patient, to compensate the paralyzed muscles by means of mechanical external force, to maintain the normal line of force of the affected limb, to stabilize the knee joint to support the body weight, and to avoid knee joint softening If it causes falls, it can also improve walking, assist patients in standing and walking training, and correct abnormal movement patterns. In addition, the device has a light structure and is easy to wear, which can effectively reduce the energy consumption of patients when walking.
