Lighting and shooting retractor applied to lumbar surgery intermuscular approach

Abstract

The invention discloses a lighting and shooting retractor applied to lumbar surgery intermuscular approach in the technical field of surgical instruments. The retractor comprises a sleeve, a movable retractor is clamped in the inner cavity of the sleeve, a movable retractor fastening screw is in threaded connection with the outer wall of the sleeve, a round bar is welded on the top wall of the sleeve, a threaded part is arranged on the outer wall of the round bar, the outer wall of the round bar is sleeved with a rotary drum, a thread meshing part is arranged at the left side of the inner wallof the inner cavity of the rotary drum, a baffle ring is fixedly mounted on the right side of the inner wall of the inner cavity of the rotary drum, a limit ring is in threaded connection with the left wall of the rotary drum, a support rod is clamped in the inner cavity of the support rod, a fixed retractor is welded on the bottom wall of the support rod, a slide rail is arranged on the top wallof the support rod, a sliding groove is formed in the top wall of the support rod, a knuckle bearing block is clamped on the top wall of the slide rail, and a lighting and shooting assembly is clamped in the inner cavity of the knuckle bearing block. The device is simple to operate and convenient to use, the labor intensity of a user can be effectively reduced, and effective surgery field lighting and shooting of minimally invasive incisions are realized.

Description

technical field [0001] The invention discloses an illumination and camera suction hook applied to transmuscular space approach in lumbar spine surgery, and specifically belongs to the technical field of surgical instruments. Background technique [0002] In today's era of rapid development of surgical science, surgical operations tend to be minimally invasive, and the incisions are getting smaller and smaller. Traditional surgical instruments can no longer meet the surgical field exposure requirements of today's minimally invasive small incisions. This product integrates effective exposure of the surgical field. Combined with the operating field lighting and camera system, it can effectively improve the quality of minimally invasive incision infusion, speed up the operation process, and shorten the operation time, thereby reducing unnecessary complications caused by long-term operations. [0003] Column disease is a frequent human disease, especially with the change of envir...

Problems solved by technology

However, the insufficient exposure of the posterior column structure of the thoracolumbar spine, unreliable fixation, excessive stripping of soft tissues, inappropriate application of distractors, and long-term and large-scale stretching of the paraspinal muscles not only affected the operation. Operation, increase medical risk and operation time, may also cause extensive and serious damage to the paraspinal muscles, resulting in thoracolumbar surgery failure syndrome, which seriously affects the therapeutic effect of thoracolumbar surgery and the quality of life of patients

At present, in the minimally invasive surgery of the posterior thoracolumbar spine, the existing products cannot meet the needs of minimally invasive small incision surgical field exposure, and cannot effectively illuminate and photograph the minimally invasive incision
