Description

A lower extremity positioning device suitable for radiographing after knee arthroplasty

technical field

The utility model relates to the field of medical appliances, in particular to a lower limb positioning device suitable for radiographing after knee joint replacement.

Background technique

At present, with the development of population aging, senile degenerative diseases are gradually increasing, such as the incidence of knee arthritis is getting higher and higher, seriously affecting the quality of life of patients, and seriously affecting work and life. The main manifestation of knee arthritis is pain at rest, which can be relieved after walking for a while, and then the pain begins again. In severe cases, the knee joint is swollen and effused, making it difficult to walk. Patients often need to use crutches and wheelchairs. Clinical treatment, conservative treatment with drugs, massage, physical therapy, etc. can achieve certain effects, but cannot solve the fundamental problem. In recent years, thanks to the advancement of surgical techniques and the improvement of medical equipment, more and more patients with knee arthritis have undergone knee replacement surgery. Therefore, in order to optimize the surgical effect, research on knee replacement surgery has been continuously carried out . For postoperative reexamination of the knee joint anteroposterior and lateral radiographs, it is often encountered that the radiology department cannot obtain satisfactory reexamination films in clinical practice, so it is impossible to effectively understand the placement position of the joint prosthesis during the operation, which often delays the disease.

The standard for taking radiographs is that the lower limbs should maintain a neutral position. The so-called neutral position radiograph requires that the central axis and the horizontal plane of the lower limbs should be kept vertical (the indirect display is that the toes of the patient’s lower limbs are vertically facing the sky). The key to this problem is that when the radiology department reexamines the film, due to the influence of gravity on the lower limbs, it is difficult for the patient to maintain the muscle strength of the lower limbs after the operation, because the patient's lower limbs always keep external rotation during the filming, and the normal position cannot be obtained. standard bit slices.

Utility model content

The technical problem mainly solved by the utility model is to provide a lower limb positioning device suitable for radiographing after knee joint replacement, which can keep the lower limbs of the injured in a neutral position during the photographing process to achieve the best photographing Effect, and reduce the pain of the injured, shorten the time of filming.

In order to solve the above-mentioned technical problems, a technical solution adopted by the utility model is: to provide a lower limb positioning device suitable for radiographing after knee joint replacement, which is used on the platform for radiographing, and can be used for radiographing after knee joint replacement. The lower limbs of the injured person are positioned when taking pictures, including: a base, a fixed side plate, a sliding side plate, a sliding buckle and a sole fixation plate, the base is fixed on the platform, and the sole fixation plate is vertically installed on the On the base, the fixed side plate is vertically installed on the base, and is vertically installed with the sole fixation plate, and the slide button is installed at the joint between the sole fixation plate and the base, the The sliding side plate is slidably arranged vertically on the base through the slide buckle, and is vertically arranged with the sole fixing plate, and the fixed side plate and the sliding side plate are arranged symmetrically.

In a preferred embodiment of the present utility model, the said foot fixation plate has a triangular structure.

In a preferred embodiment of the utility model, the height of the fixed side plate and the sliding side plate is 15-20 cm.

In a preferred embodiment of the present utility model, the lengths of the fixed side panels and the sliding side panels are 30-35 cm.

The beneficial effect of the utility model is that the foot of the injured person is fixed by using the sole fixing plate vertically installed with the base, and the calf of the injured person is fixed by the fixed side plate and the sliding side plate, and the sliding side plate is fixed by using the sliding buckle. It can be adjusted according to the thickness of the injured calf, so that the lower limbs of the injured always maintain a neutral position during the filming process, so as to achieve the best filming effect, reduce the pain of the injured, and shorten the filming time.
