Long bone locking steel plate traction external fixator and using method thereof

Abstract

The invention discloses a long bone locking steel plate traction external fixator and a using method thereof. The external fixator comprises an inner ring groove steel plate, an outer traction support, a clamping needle traction base, a traction rod and a bone needle, the inner ring groove steel plate is fixedly connected to a long bone and located in a body, the outer traction support is connected to the inner ring groove steel plate through a connecting rod and located outside the body, the clamping needle traction base is arranged on the outer traction support and slides in the length direction of the outer traction support, the traction rod is parallel to the outer traction support, both ends of the traction rod are connected to the outer traction support and the clamping needle traction base respectively, and the bone needle is arranged on the clamping needle traction base. The clamping needle traction base can be connected to the outer traction support in a bidirectional mode torealize bidirectional sliding movement and has a wide range of applications. An adjusting bolt is adjusted to enable the traction rod to drive the clamping needle traction base to move outwards, thenthe bone block is drawn at a fixed speed to slide to the far end, which is easy and stable to control, and the operation success efficiency is high.

Description

technical field [0001] The invention relates to the technical field of medical tools, in particular to a long diaphysis locking plate stretching external fixator and a use method thereof. Background technique [0002] The use of external fixation brackets to treat bone defects and osteomyelitis began in the 1960s. After half a century of continuous development, it has become an ideal and effective treatment plan for various orthopedic diseases. The clinical excellent rate of more than 10 years has reached More than 90%, known as an important milestone in the history of orthopedic development in the 20th century, for patients with osteonecrosis, comminuted fracture and dislocation that cannot be reset, osteoarthritis with pain and movement disorders, rheumatoid arthritis with stiffness or difficulty in movement, etc. Symptoms can be significantly relieved or eliminated, the range of motion of joints can be improved to a certain extent, and the appearance of deformed limbs can...

AI Technical Summary

Problems solved by technology

External fixation brackets also have good effects on diseases such as osteomyelitis, bone defect, limb shortening, orthopedic reduction, but have higher requirements in application

The traditional treatment for osteomyelitis is still to achieve the therapeutic purpose through the sliding of bone fragments with external fixation brackets. The shortcomings of being difficult to control, unable to achieve two-way sliding and difficult for doctors to learn
