Spinal-orthopaedic-rod connecting device flexibly adjusting installing position

Abstract

The invention discloses a spinal-orthopaedic-rod connecting device flexibly adjusting an installing position. The spinal-orthopaedic-rod connecting device comprises an inner locking sleeve, an outer connecting sleeve and a locking nut, wherein a guiding hole is axially formed in the inner locking sleeve, a clamping conical head is arranged at one end of the inner locking sleeve, elastic notches are formed in the clamping conical head in the axial direction, and the outer conical surface of the clamping conical head is in adaptive fit with the inner conical surface of the outer connecting sleeve; a connecting hole is formed in the outer collecting sleeve, the free moving end of the outer collecting sleeve is in locking fit with one end face of the locking nut, the locking nut is in thread fit with the outer surface of the inner locking sleeve, and clamping openings are formed in the outer surface of the inner locking sleeve. According to the spinal-orthopaedic-rod connecting device, theguiding hole in the inner locking sleeve can slide up and down along orthopaedic rods, the installing position and a connecting position can be freely adjusted, connection between the connecting holes can be carried out through a connecting rope and the like so that flexible connection of the orthopaedic rods can be achieved, connection between the orthopaedic rods has stretchable space, and thegrowth potential of a spinal base body is protected.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to a spinal orthopedic bar connection device with a simple structure and convenient use, which can flexibly adjust the installation position. Background technique [0002] During the growth process of the human spine, when there are defects in the development of the vertebral bodies, deformities such as scoliosis, hunchback, lordosis, and kyphosis may appear. If it is small, it may also limit the growth of height and have a great adverse effect on the human body. Therefore, in the medical field, how to effectively correct the scoliosis of young children and adolescents has always been a concern of those skilled in the art. At present, the main process of the treatment plan adopted in spinal orthopedics is as follows: According to the development of the patient's spine, the preparation before the operation is carried out; the rod-shaped correction strip is implanted into the...

Problems solved by technology

[0003] At present, spinal orthopedics use hard metal rods to connect two orthopedic rods, so that a frame structure can be formed between the orthopedic rods and the fixation nails, which limits the flexibility and growth potential of the spine. At the same time, the existing spinal orthopedic The connecting parts of the device are often not free to adjust the connection position, which is highly restrictive during the operation, which affects the surgical effect, causes harm to the human body, and affects the normal growth of the spine. Therefore, it is important to develop a spinal orthopedic rod connection device that can flexibly adjust the installation position. It means that the orthopedic rods can be connected with the flexible connecting rope, so that the connection between the orthopedic rods has a flexible space and protects the growth potential of the spinal matrix
