Problems solved by technology
[0002] At present, when the lumbar herniation disc opening deviates from the intervertebral space, or the lumbar cartilage plate ruptures, it is necessary to use the fenestration correction chisel for surgery. Currently, in order to facilitate the use of the fenestration correction chisel, the chisel is connected by a threaded rod for easy replacement , but the chisel will rotate during use, causing the chisel to be unstable, and the direction of the LED light for lighting on the handle is single, which is easy to form shadows and affect the operation

The invention discloses a windowing correction chisel for a lumbar disc herniation operation, and relates to the technical field of medical instruments, a metal clamping piece is of a V-shaped structure, and the bottom of the metal clamping piece is fixed on a chisel; clamping holes are formed in the middle parts of the left and right side walls of the metal clamping pieces; through holes are formed in the upper parts of the left and right side walls of the metal clamping pieces; the fixing block is arranged in the metal clamping piece, and the left side wall and the right side wall of the fixing block are attached to the left inner side wall and the right inner side wall of the metal clamping piece respectively. The two clamping blocks are movably clamped in the left clamping hole and the right clamping hole respectively; the clamping block and the fixing block are integrally formed, and the outer side wall of the clamping block is obliquely arranged from outside to inside from top to bottom; the connecting shaft is fixed at the upper end of the fixed block; the chisel is convenient to replace, the connection is stable, the chisel is prevented from falling off due to instability, and the safety is improved; lampshades of the illuminating lamps are obliquely arranged from outside to inside from high to low, light rays of the illuminating lamps are emitted to the bottom of the chisel, so that the operation portion of the chisel is illuminated, the illuminating lamps jointly illuminate, and a shadowless operation environment is formed.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a fenestration correction chisel for lumbar disc herniation surgery. Background technique [0002] At present, when the lumbar herniated intervertebral disc is opened to deviate from the intervertebral space, or the cartilage plate of the lumbar spine is ruptured, it is necessary to use the fenestration correction chisel for surgery. Currently, in order to facilitate the use of the fenestration correction chisel, the chisel is connected by a threaded rod for easy replacement , but the chisel will rotate during use, causing the chisel to be unstable, and the LED light on the handle has a single direction, which is easy to form shadows and affect the operation. Contents of the invention [0003] The purpose of the present invention is to address the defects and deficiencies of the prior art, and propose a fenestration correction chisel for lumbar disc herniation surgery, ...
