Problems solved by technology

The free distraction device is prone to displacement during operation
During the surgical operation, the position of the patient may change slightly relative to the operating bed, and the traditional spreader fixed on the operating bed will also shift on the patient, affecting the stability of the surgical field of view
During the operation, the distraction system is unstable and easily deviates from the surgical target, which affects the operation and safety of the operation

Abstract

The invention discloses an exposure and distraction device for lumbar posterior surgery. The exposure and distraction device comprises a first end fixing piece, a universal connecting mechanism, a main drag hook and a second end fixing piece, wherein one end of the first end fixing piece is connected with one end of the universal connecting mechanism, the universal connecting mechanism is provided with two connecting ends, the head of each end can rotate in multiple planes and multiple angles, the main drag hook is directly or indirectly connected with the other end of the universal connecting mechanism side, the second end fixing piece is arranged at the tail end of the head of the main drag hook, the head end of the main drag hook is connected with the second end fixing piece, and the tail end of the main drag hook is connected with the first end fixing piece through a series of connectors, so that the main drag hook is stable and plays a distraction role.

Description

technical field [0001] The invention relates to the technical field of lumbar posterior surgery, in particular to a distraction device for lumbar posterior surgery exposure. Background technique [0002] In recent years, patients with lumbago and leg pain have increased year by year, and its prevalence has been as high as 60%-80%, which seriously affects people's health. Lumbar degenerative diseases such as lumbar disc herniation, lumbar spinal stenosis, and spondylolisthesis are common causes of low back pain. Although most low back and leg pain can be relieved by conservative treatment such as drugs, physical therapy, and rest in the early stage. However, if the patient's condition progresses during follow-up, if there is a decline in lower limb muscle strength, cauda equina syndrome, or symptoms that seriously affect work and life, surgical treatment is often required. Posterior lumbar interbody fusion is a commonly used surgical treatment for lumbar degenerative diseas...
