Description

An easy-to-operate cranial-pelvic ring

technical field

The invention relates to the technical field of correction and nursing, in particular to a cranial and pelvic ring that is easy to operate.

Background technique

Adolescent idiopathic scoliosis is a common spinal deformity. The greater the degree of scoliosis, the more obvious the characteristics of trunk imbalance, head deviation from the central axis, unequal shoulders, razor back, and thoracic collapse. Scoliosis is often not a simple problem of spinal curvature, and the thoracic cage will also be deformed. Squeezing the thoracic cage will reduce lung function and lung capacity, seriously affecting the development of important organs, often accompanied by cardiopulmonary dysfunction and spinal nerve damage.

After searching, for example, the patent number CN209122558U discloses a new type of skull and pelvis ring. The novel cranial pelvic ring comprises a cranial ring device for fixing the skull, a connecting device and a pelvic ring device for fixing the pelvis, the skull ring device and the pelvic ring device are connected by the connecting device; the connecting device includes a connection The connecting rod includes an upper rod body and a lower rod body, and a pressure sensor is connected between the upper rod body and the lower rod body. Therefore, the treatment of scoliosis can be better achieved, and the recovery of the spine can be monitored.

Another example is the patent No. CN208756124U, which discloses a hinged cranial pelvic ring, including a connecting rod assembly, the upper end of the connecting rod assembly is connected with a skull ring assembly, the lower end of the connecting rod assembly is connected with a pelvic ring assembly, and the connecting rod assembly includes a positive Reverse threaded rod, both ends of the positive and negative threaded rods are connected with a locking frame body threadedly, the locking frame body ball is hinged with one end of the ball head rod, and the other end of the ball head rod is rotatably connected to one end of the adjusting sleeve. The other end is rotatably connected with a curved rod, the skull ring assembly includes a skull ring, the pelvic ring assembly includes a size-adjustable pelvis ring, the pelvis ring includes two semicircular rings that cooperate with each other, and the skull ring and the pelvis ring are connected by a hook assembly The bent rod and the hook assembly include a hook, and the hook is hinged with the bent rod ball. It can be adjusted at any position in space, can be well adapted to the shape of various patients' back deformities, avoid the problems of irregular artificial shaping and easy rebound, can effectively shorten the operation time, reduce the difficulty of the operation, and be easier to popularize.

However, the currently used basin ring is mainly a fixed structure, does not have the rebound self-locking function to adjust the limit according to the different body structure, does not have the auxiliary function to quickly adjust and adapt to the height according to different heights, and does not have strong anti-slip stability. The structure does not have the girth adjustment function that can be self-locked and quickly adjusted, which is not conducive to restoration of use. Therefore, it does not meet the existing needs. For this, we propose a cranial pelvic ring that is easy to operate.
