Embodiment
[0029] Such as figure 1 and figure 2 The operating channel device for minimally invasive spine endoscopy shown includes a main working channel 1 and a secondary working channel 2 arranged side by side, a connecting plate 8 arranged between the main working channel 1 and the secondary working channel 2, and a device The water inlet 5 and the water outlet 6 on both sides of the connecting plate 8 and connected with the auxiliary working channel 2 respectively.
[0030] The main working channel 1 is used to pass the spine minimally invasive operation instrument 3, and the auxiliary working channel 2 is used to pass the intervertebral foraminal mirror 4. Compared with the previous method of setting in the same channel, this device can avoid the operation of surgical instruments and the intervertebral foraminal The mutual influence of intervertebral foramen can make the surgical field of the foramen mirror wider, improve the efficiency of foramen shaping, and reduce the operation time...

The invention relates to an operation channel device for a spinal minimally invasive endoscope, wherein the operation channel device includes a main working channel, an auxiliary working channel, a connecting plate which is arranged between the main working channel and the auxiliary working channel, an water inlet and a water outlet; the main working channel and the auxiliary working channel are arranged in parallel; the water inlet and the water outlet are arranged on both sides of the connecting plate respectively and communicate with the auxiliary working channel. Compared with the prior art, through combination of the main working channel and the auxiliary working channel, the operating visual field of a transforaminal endoscopic spine system is extended, the forming efficiency of theintervertebral foramen is improved, and the operation time is shortened; through the design that the auxiliary working channel is longer than the main working channel, the visual field of a surgical site is more fully exposed, the flexible removal of diseased tissues is facilitated and surgical injury is avoided; with single arrangement of the channel water inlet and the water outlet, the volume of the endoscopy is not occupied, operation devices of various spinal endoscopes can be combinedly contained in the main channel, the bone and soft tissue obstacles can be treated at the same time, andthe operation of the spinal minimally invasive endoscope is more flexible and efficient.
Description
Technical field [0001] The invention belongs to the technical field of medical devices, and relates to an operating channel device for a spinal minimally invasive endoscope. Background technique [0002] Minimally invasive surgery for spine intervertebral foramen enlarges the surgical field of vision through the intervertebral lens, which can clearly display the anatomical structure of each tissue in the operation area, significantly reduce the damage to the tissue structure of the operation, and make the operation of the intervertebral disc a minimally invasive operation. Due to minimally invasive requirements, the operating channel needs to accommodate spine minimally invasive operating instruments, intervertebral foraminal mirrors and other surgical instruments at the same time, resulting in inconvenient operation of the various instruments in the channel and mutual influence, resulting in a small field of view of the foraminous mirror, which is not conducive to surgery Operat...
