Spine traction wheelchair with cranial ring

Technical Field

The utility model relates to a sitting posture backbone pulls auxiliary assembly technical field, concretely relates to backbone pulls wheelchair with cranium ring.

Background

Preoperative distraction orthopedic techniques for severe scoliosis (particularly the cervico-thoracic region) typically employ a cranio-pelvic ring distraction instrument. The purpose of scoliosis treatment is to obtain firm fusion under the condition of restoring spinal balance, prevent the progress of deformity, correct deformity and improve the appearance and the quality of life. The heart and lung function of patients with severe scoliosis is seriously affected due to the serious deformity of the spine and the thorax, and the body is thin and weak. If the posterior operation is directly carried out to correct the scoliosis, not only the operation is difficult to carry out, but also the patients cannot bear the operation treatment due to poor respiratory function and thin and weak bodies. The scoliosis of a patient can be corrected to a certain extent before an operation through traction, so that the respiratory function and the physique are improved, and the spinal orthopedic operation can be smoothly implemented.

The cranium-pelvic ring traction is realized by a pelvic needle which acts on a skull screw and a pelvis, the good and bad traction effect is related to the creep growth capacity of the traction tissue, so the bearing capacity of the skull and the pelvis and the growth potential of the body of a patient are considered when the cranium-pelvic ring traction is treated. It has the following disadvantages: firstly, the traction time is long, so that the treatment period of a patient is prolonged, and the maximum time can reach half a year. Along with the extension of traction time, the infection chance at the eye of the pelvic needle is increased, and the pelvic needle is easy to loosen and sink. Because the iliac bone can not be taken as bone grafting material due to the existence of the basin needle, artificial bone is required to be added during fusion, and foreign body reaction and infection are possible to be caused; secondly, discomfort such as neck pain, dysphagia and the like easily occurs in the later stage of traction, so that the tolerance of patients is influenced, and particularly, patients with smaller ages are possibly unwilling to cooperate with treatment in the later stage; and secondly, the nursing difficulty is increased, the patient has certain difficulty in sleeping in bed during traction, in order to prevent the frame from directly abutting on the bed, the patient must be padded up by a thick cushion and needs to be frequently helped to turn over, and the patient needs to pay attention to protection when walking off the bed to prevent falling.

The skull ring is an oval and semi-closed ring body 1 which can be fixedly arranged on a skull, skull nails 4 used for fixing the whole ring body 1 on the skull are uniformly distributed around the ring body 1, fixed base bodies 5 used for connecting traction ropes 15 are uniformly distributed around the ring body 1, a connecting body 2 is arranged between two open ports of the ring body 1, and connecting screws 3 which play a role in stabilizing and balancing the fixation of the skull ring are also arranged between the two ports. The number of the cranial nails 4 is 4, and the number of the fixed seat bodies 5 is 2-4. The skull ring is oval, is divided into a large, a medium and a small, can be shaped according to the head shape of a patient, keeps a distance of 5-10 mm with the head circumference, is easy to generate compression when being too close, and is unstable when being too far. The wall thickness of the ring is 2-3 mm, the width of the ring wall is 16-18 mm, the ring wall is too narrow, too thin and not firm enough, and cannot bear the supporting force, and the ring wall is too wide and thick and increases the weight. When a patient lies on the patient with the craniocerebral ring, the occiput can not directly contact with the pillow, and the neck of the patient needs to be pressed against the pillow, so that the occiput of the craniocerebral ring is upward. The skull ring is provided with 4 fixed seat bodies 5,4 skull nails 4, the length of the skull nail 4 is 60mm, the diameter of the external thread is 6mm, the length of the skull nail tip is 5mm, and the diameter of the base part of the skull nail tip is 2mm. When fixed to the skull, only the tip of the cranium nail penetrates into the cortical bone to prevent slipping on the cortical bone. The skull ring is fixed on the skull by 4 skull nails 4 which are mutually pressed to keep stable.

The number of the fixed hoisting rings 13, the pulley frame bodies 14 and the pulleys 12 is four.

When the skull ring is installed in use: the operation can be carried out under local anesthesia, the first 2 cranium nails 4 of the cranium ring are preferably nailed at the position 1.5-2.0 cm above the outer side of the brow tip, the second 2 cranium nails 4 are preferably nailed at the position 1.5-2.0 cm above the back of the auricle, the cranium nails 4 are alternately screwed down at the front and back opposite angles, and the periphery of the cranium ring is adjusted to keep consistent distance with the skin. The elastic extrusion force of the skull ring and the outward supporting force of the four skull nails 4 ensure that the skull nails 4 are arranged on the outer plate of the skull. Because the head nail 4 is fixed below the maximum diameter of the skull, the head nail tip penetrates into the skull outer plate, and the phenomena of craniocerebral ring moving upwards or skin traction can not occur in traction. The cranial nail 4 is screwed down and then retreated backwards for a half circle, so that the skin around the cranial nail 4 is restored to the original position. The puncture site was sterilized with alcohol several times a day.
