[0003] In the use of lumbar minimally invasive surgery channels on the market, the most common channel is a cylindrical channel, but because the junction of the lumbar spinous process and the lamina is curved, it may not be possible to completely conform to the cylindrical-shaped flat channel, and When the openings of regularly combined channels reach a certain level, professional channel expansion devices need to be assisted to enter, and then professionals need to jointly remove the regularly combined channels to start treatment operations, and during the removal process, there may be interference with the surrounding areas or The position of the spinous process of the lumbar spine conflicts, which will bring a certain degree of psychological pressure and injury to the doctor and the patient, and affect the follow-up treatment. Therefore, we propose a slope-type lumbar minimally invasive surgery channel

The slope type lumbar vertebra minimally invasive surgery channel comprises a main body, a combined dual-purpose mechanism, a hidden adjusting mechanism, a buckling type protection mechanism and an auxiliary precision mechanism, the combined dual-purpose mechanism is arranged in the middle of the main body, the hidden adjusting mechanism is arranged on the side edge of the combined dual-purpose mechanism, and the buckling type protection mechanism is arranged on the side edge of the combined dual-purpose mechanism. A buckling type protection mechanism is arranged on the periphery of one side of the main body, auxiliary precise mechanisms are distributed on the periphery of the main body, and the hidden type adjusting mechanism comprises an upper mounting piece. According to the slope-type lumbar vertebra minimally invasive surgery channel, when the slope-type connecting arc head is gradually retracted into the main body, the contact range of the slope-type connecting arc head and the joint of the lumbar vertebra spinous process and the vertebral plate is also reduced, and at the moment, the angle between the slope-type connecting arc head and the main body is gradually changed to a plain end channel; therefore, the fitness of various radians can be guaranteed as much as possible, and a user can obtain a wide to-be-treated position after subsequent distraction.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a slope-type minimally invasive surgical channel for lumbar vertebrae. Background technique [0002] Nowadays, medical lumbar fusion has also become an important solution for the treatment of lumbar spine diseases that require stabilization. It is widely used in the treatment of lumbar spine trauma, intervertebral disc degeneration, lumbar spondylolisthesis, lumbar intervertebral space infection and other diseases. , lumbar spine and other surgeons take minimally invasive surgery as the preferred treatment plan, and a minimally invasive surgical channel system is required during the treatment process, and this plan mainly focuses on the last group of channels in the combination of regular channels. [0003] In the use of minimally invasive lumbar spine surgery channels on the market, the most common channel is a cylindrical channel, but due to the curvature of the connect...
