Description

Sliding Scoliosis Traction Table

【Technical field】

The utility model relates to a plastic nursing appliance for non-surgical treatment of bones or joints, in particular to a sliding traction bed used for traction of the spine.

【Background technique】

IS (idiopathic scoliosis) is a pathological change in which the spine bends sideways and the thorax and ribs deform. It often occurs in adolescence, and its etiology is still unclear. Studies have shown that soft tissue contracture on the concave side is an important clinicopathological manifestation of scoliosis. This pathological manifestation may be secondary to the appearance of scoliosis, or it may be the primary pathological change that causes IS. At present, for patients with scoliosis degree less than 40°, orthopedic braces can be worn, or traction and supplemented by physical therapy can be used to control the continued development of scoliosis; for patients with scoliosis degree greater than 40°, surgical treatment is often required clinically. During scoliosis surgery, in order to prevent neurological complications during and after surgery, preoperative traction has become an effective and routinely used adjuvant treatment.

Traction therapy for scoliosis patients can loosen the paravertebral soft tissue, loosen the ligaments and small joints between the vertebrae, which is conducive to surgical correction and avoid the occurrence of paraplegia. Therefore, effective preoperative traction can successfully correct adolescent scoliosis. very important. Of course, the monitoring of traction process, effect observation and method improvement also belong to the scope of perioperative nursing research. In addition, preoperative traction can estimate the flexibility of the spine and predict the effect of surgical correction. It is generally believed that the cobb angle of the preoperative suspension image or convex lateral flexion (bending position) X image minus 10 degrees can be calculated as the COBB after surgical correction. The predicted degree of the angle.

There are many traction methods for scoliosis, such as head-pelvic ring traction, femoral supracondylar traction of the skull and lower limbs, femoral traction with occiput-mandibular belt, scoliosis anti-suspension traction, self-suspension traction, traction in supine position with pillow, etc. Although the traction method has a certain effect, there are still some problems in practical application. Someone has developed a new type of spinal extender for instrumental traction on scoliosis patients, which improves the patient's comfort and tolerance during the traction process while achieving effective traction, and achieves better expected results. It is believed that the application of this The comprehensive effect of traction by the extender is better than suspension traction. However, due to some problems in the structural design and material selection of the extender, deformation may occur during use, and the repair rate is high.

【Content of invention】

The technical problem to be solved by the utility model is to overcome the above-mentioned defects in the prior art and provide a sliding scoliosis traction bed with reasonable structure, comfortable and effective while achieving the expected traction effect.

The utility model solves its technical problems by adopting the following technical solutions: a sliding scoliosis traction bed, comprising a bed frame and a traction drive device fixed on the bed frame, characterized in that: a part of the bed surface of the traction bed is set In order to fix the bed surface, the other part is set as a movable bed surface that can slide longitudinally along the traction bed. A pulley adjustment rod is fixed and erected at one end of the bed frame, and the traction wire rope in the traction driving device passes through the fixed pulley fixed at one end of the bed frame and The fixed pulley fixed on the pulley adjusting rod is connected with the rigging belt, and there are side pushing rods on both sides of the bed frame that can be adjusted vertically and horizontally.

Because the utility model sets the bed surface carrying the weight of the patient's body as a sliding follow-up structure, the traction force acts on the patient's body without hindrance, which can reduce the work intensity of the operator while ensuring the therapeutic effect.

The height of the equipped pulley adjustment lever can be adjusted freely, and the force angle of the traction wire rope on the traction part can be adjusted through the change of the height of the pulley to adapt to the different heights of patients or different traction treatment requirements.

According to the position of the key vertebrae of the patient, the side ejector rod can be installed in different positions arbitrarily through the sliding rods on both sides of the bed body, and the side ejector rod can be progressively pushed out by rotating the handle, and the strength can be tolerated by the patient Therefore, it can be adapted gradually according to the patient's own endurance to prevent injury. At the same time, after pushing the top from the side, the expected traction effect can be achieved with a small longitudinal traction force, which improves the patient's comfort.

While the utility model is effective in traction, it also has the characteristics of convenient and effective use, low repair rate and more comfort.
