Instrument for anterior approach operation of thoracolumbar

Abstract

The invention provides a set of instruments for anterior thoracic and lumbar vertebra surgery, comprising a long-handle drag hook I, a long-handle periosteum detacher II, a long-handle osteotome III, a long-handle curet IV and a long-handle endplate curet V; the long-handle drag hook I comprises a drag hook point 1, a head section 2, a body section 3, a back end circular hole 4; the long-handle periosteum detacher II comprises an obtuse head section 5, a body section 6 and a handle 7; the long-handle osteotome comprises a flat osteotome head 8, a body section 9 and a back end 10; the long-handle curet IV comprises an obtuse curet head 11 with hook, a body 12 and a conical handle 13; the long-handle endplate curet V comprises a hollow curet head 14 with elliptic structure, a body section 15 and a handle 16. The invention has advantages of reasonable design, easy manufacture process, and low cost. By using the instruments of the invention, smaller surgical incision, improved surgery range of vision, optimized operative procedure, reduced surgery difficulty, reduced hemorrhage in surgery and shortened surgery time can be obtained.

Description

technical field [0001] The invention belongs to surgical instruments, and relates to surgical instruments for spine surgery, and mainly relates to a set of instruments for thoracolumbar anterior surgery. Background technique [0002] Accidents such as traffic, work injury, and falling from heights are likely to cause spinal fractures, 90% of which are thoracolumbar fractures. For such fractures, especially severe blowout fractures, conservative treatment is ineffective and surgical treatment is often required. [0003] Currently, surgical treatment includes anterior surgery and posterior surgery. Due to the advantages of simple approach, few complications, and significant short-term curative effect, the posterior approach has become the most commonly used surgical method for the treatment of thoracolumbar fractures. It achieves reduction and decompression of vertebral fractures by opening the intervertebral space and tightening the anterior and posterior ligament complexes...

AI Technical Summary

Problems solved by technology

[0005] Although the anterior approach has the above advantages, the traditional anterior approach also has some obvious defects, such as: large surgical trauma, difficulty in exposing the diseased vertebra, excessive bleeding during the operation, long operation time, and difficult revision, etc. These technical bottlenecks are serious It restricts its wide clinical application, especially in some grass-roots hospitals, often regards posterior surgery as the final treatment plan for all thoracolumbar fractures
