Description

Lower limb traction device

The technical field is as follows:

the utility model belongs to the technical field of medical instrument and specifically relates to a low limbs draw gear.

Background art:

in recent years, with the aging and the increasing of population, the prevalence rate of osteoporosis is increased year by year, the incidence rate of hip brittle fracture is increased, especially, old intertrochanteric fracture and femoral neck fracture are more, shortening and varus and valgus deformity are easy to occur on affected side limbs after hip fracture, especially intertrochanteric fracture, because the fracture belongs to the joint capsule external fracture, shortening and valgus are easy to occur, fracture nonunion, shortening deformity union and femoral head necrosis are easy to occur on femoral neck fracture, for most patients with good physical conditions, surgical treatment is mostly adopted, the life autonomy of the patients can be quickly recovered, and the occurrence of related complications is reduced. However, some patients with serious basic diseases, such as serious cardiovascular and cerebrovascular diseases, uncontrollable hypertension, diabetes and the like, cannot tolerate anesthesia and surgical treatment when the affected limb and hip are affected by ulcer and other infections, and only can adopt conservative treatment. The fracture of a patient with the fracture end which is not obviously displaced can be naturally healed by adopting the conventional skin traction treatment, and the complications are less, but if the fracture end is obviously displaced, especially for the patient with the limb which is shortened and the external rotation is heavier, the fracture end is often accompanied with the abnormal healing or even non-healing by adopting the conventional skin traction treatment or the external fixation treatment of the hip brace of the lower limb, and the complications are more, such as: shortening deformity of affected limb, outward rotation deformity, etc. While the defects of infection, pain, iatrogenic fracture, nursing difficulty and the like easily occur at the traction nail path by adopting traction treatment on the femoral condyle or tibial tuberosity, and conventional conservative treatment is not performed at present.

The T-shaped shoes are designed by students, a traditional T-shaped shoe bottom support is made of a wood material, the anti-rotation strength is weak, patients wear the T-shaped shoes and lie in bed to perform conservative treatment, and serious complications such as heel skin pressure sore of affected limbs, deep vein thrombosis and the like easily occur when the traditional T-shaped shoes and the bed brake are worn for a long time. Even if the traditional T-shaped shoe device can improve the outward rotation deformity to a certain degree, the limb shortening cannot be corrected well, and the affected limb is easy to have shortening deformity complications and leave serious sequelae. In addition, the common lower limb skin traction device is designed simply, the contact force between the soft material and the skin is too concentrated, the outer sleeve traction device is directly contacted with the bed surface, the friction force is larger, the traction force is limited, the limb short-shrinkage correcting function is realized to a certain degree, no limb anti-rotation function is provided, and the lower limb on the affected side is easy to turn over and deform, and the fracture broken end is easy to heal.

The utility model has the following contents:

the utility model provides a lower limb traction device for overcoming the defects in the prior art.

The application provides the following technical scheme:

a lower limb traction device comprises an underframe, and is characterized in that a foot sleeve and a shank sleeve are connected to the underframe, the shank sleeve is further arranged on one side of the underframe, a traction belt is connected between the shank sleeve and the shank sleeve, a ring body is arranged on the foot sleeve, and a heavy hammer is connected to the ring body through a pull rope.

On the basis of the technical scheme, the following further technical scheme can be provided:

the foot cover comprises a foot placing groove, an opening is formed in one end of the foot placing groove, a toe cap cover wrapping toes is connected to the opening, a first nylon hasp is arranged on the foot placing groove, and the toe cap cover is made of a flexible breathable material.

The shank sleeve is of a through groove type structure, one end of the shank sleeve is fixedly connected with the foot sleeve, a flexible liner layer is arranged on the inner side of the shank sleeve, a group of air holes are further formed in the shank sleeve, and a group of second nylon buckles are arranged on the shank sleeve.

The underframe comprises three fixing strips which are distributed in parallel, and the fixing strips are connected with connecting plates, so that the underframe is of a structure shaped like a Chinese character 'wang'.

The thigh sleeve comprises an outer layer, a flexible inner layer is connected to the outer layer, and the end parts of the two ends of the outer layer are connected through a pair of third nylon buckles to form a ring.

A traction column is connected between the ring body and the foot sleeve.

Utility model advantage:

the utility model discloses simple structure, convenient to use close the needs of different sizes and different limbs hip fracture, have ensured the travelling comfort of patient when wearing, can make the affected limb further correct the limbs shortness deformity on the basis of correcting the external rotation deformity, and can prevent to press complications such as sore formation to patient's limbs function is resumeed to the at utmost.

Particularly, the near-end thigh traction device is designed to be connected with the detachable cotton leg sleeve, so that traction force of the traction part is transferred to the thigh far end of the affected limb, and the risk of continuous traction injury of the skin of the crus is prevented; the underframe is fixedly connected with the lower leg sleeve and the foot sleeve into a structure shaped like a Chinese character 'wang' by a stainless steel cylinder, so that the friction between the underframe and the bed surface is reduced to the maximum extent under the condition of effectively preventing the limb from rotating inside and outside, and the maximum traction effect is generated;

the skin at the traction part can be relaxed and rested at any time by adopting the nylon hasp fixing design, so that the skin is prevented from being dragged and necrotized, and in addition, the tightness can be adjusted and the device is suitable for the application of limbs with different sizes; the design of the flexible liner layer prevents the possibility of pressure sores, deep vein thrombosis, skin necrosis and the like of limbs, and the shoe toe cap made of the flexible breathable material effectively ensures the comfort of a patient.
